Majority of the recipients of these treatments are women within the reproductive age group, who according to literature may be at risk of adverse pregnancy outcomes. This pilot study is part of a study investigating adverse pregnancy outcomes among women who received Cryotherapy, Thermal ablation and Loop Electrosurgical Excision Procedure compared to the untreated women in Zambia. Materials and Methods: This descriptive study analyzed records of 886 (n = 443 treated and n = 443 untreated) women aged 15 - 49 years. The women were either screened with Visual Inspection with Acetic Acid or treated for Cervical Intraepithelial neoplasia at the Adult Infectious Disease Centre between January 2010 and December 2020. Women meeting the criteria were identified using the Visual Inspection with Acetic Acid screening records and telephone interviews to obtain the adverse pregnancy outcome experienced. Data were analysed using STATA version 16 to determine the prevalence and obtain frequency distribution of outcomes of interest. Univariate and multivariable binary logistic regression estimated odds of adverse pregnancy outcomes across the three treatments. Results: The respondents were aged 15 to 49 years. Adverse pregnancy outcomes were observed to be more prevalent in the treatment group (18.5%) compared to the untreated group (5.4%). Normal pregnancy outcomes were lower in the treated (46.3%;n = 443) than the untreated (53.7%;n = 443). The treated group accounted for the majority of abortions (85.2%), prolonged labour (85.7%) and low birth weight (80%), whereas, the untreated accounted for the majority of still births (72.7%). Women treated with cryotherapy (aOR = 2.43, 95% CI = 1.32 - 4.49, p = 0.004), thermal ablation (aOR = 6.37, 95% CI = 0.99 - 41.2, p = 0.052) and Loop Electrosurgical Excision Procedure (aOR = 9.67, 95% CI = 2.17 - 43.1, p = 0.003) had two-, six- and ten-times higher odds of adverse pregnancy outcomes respectively, relative to women who required no treatment. Conclusion: Adverse pregnancy outcomes are prevalent among women who have received treatment in Zambia. The findings indicate that treating Cervical Intraepithelial Neoplasia has been linked to higher chances of experiencing abortion, delivering low birth weight babies and enduring prolonged labor that may result in a caesarean section delivery. Cervical neoplasia treatments, particularly Loop Electrosurgical Excision Procedure, are associated with significantly increased odds of adverse pregnancy outcomes. It is essential to include information about prior Cervical Intraepithelial neoplasia treatment outcomes in obstetric care.展开更多

Methods: A comprehensive literature search was performed using the Web of Science, MEDLINE, EMBASE, and Cochrane Library databases to retrieve comparative studies. The main objective was to assess the BCVA, while reattachment rates and ocular adverse events were considered secondary measures. Rev Manager software was used for statistical analysis. Results: The literature search identified 10 articles comprising 1518 eyes, with 682 eyes in the PPV group, 193 eyes in the lens-sparing versus phaco-procedure group, and 643 eyes in the combined PPV and SB surgery group. Quality assessment revealed a low risk of bias in most domains. The meta-analysis results revealed a significant difference in postoperative BCVA between the PPV and PPV combined with SB groups (WMD = −0.17, 95% CI [0.27, 0.07], p = 0.001). The primary reattachment rates were 82.80% for PPV alone and 87.52% for PPV combined with SB (p = 0.34). The final reattachment rates did not differ significantly between PPV and PPV combined with SB (99% vs. 99.8%;RR = 1.00, 95% CI [1.01, 0.99], p = 0.96). PPV alone demonstrated a significantly reduced risk of macular edema compared to PPV combined with scleral buckling (9.9% vs. 23%;p = 0.006). The incidences of macular hole development (p = 0.46), recurrent retinal detachment (p = 0.27), proliferative vitreoretinopathy development (p = 0.48), epiretinal membrane proliferation (p = 0.77), and limited choroidal hemorrhage (p = 0.69) were not significantly different between the two groups. Conclusions: These findings suggest that PPV alone may be a more effective treatment option in terms of visual acuity (VA) improvement, lower risk of macular edema and cataract development. However, there was no significant difference in VA improvement or complication rates between the lens-sparing and phaco-procedure groups. .展开更多

However, it has several technical difficulties, because the wall of the colon is thin and due to the winding nature of the colon. The main complications of ESD comprise postoperative perforation and hemorrhage, similar to endoscopic mucosal resection (EMR). In particular, the rate of perforation in ESD is higher than that in EMR. Perforation of the colon can cause fatal peritonitis. Endoscopic clipping is reported to be an efficient therapy for perforation. Most cases with perforation are treated conservatively without urgent surgical intervention. However, the rate of postoperative hemorrhage in ESD is similar to that in EMR. Endoscopic therapy including endoscopic clipping is performed and most of the cases are treated conservatively without blood transfusion. In blood examination, some degree of inflammation is detected after ESD. For the standardization of ESD, it is most important to decrease the rate of perforation. Adopting a safe strategy for ESD and a suitable choice of knife are both important waysof preventing perforation. Moreover, appropriate training and increasing experience can improve the endoscopic technique and can decrease the rate of perforation. In this review, we describe safe procedures in ESD to prevent complications, the complications of ESD and their management.展开更多

Data on age, gender, body mass index(BMI), American Society of Anesthesiologists score, imaging findings, inflammatory index(white blood cells, interleukin(IL)-6, and C-reaction protein), visual analogue score score during hospitalization and outpatient visit, history of CP, operative time, estimated blood loss, and postoperative data(postoperative mortality and morbidity, postoperative length of hospital stay) were obtained for patients undergoing laparoscopic surgery. The open surgery cases in this study were analyzed for risk factors related to extensive bleeding, which was the major reason for conversion during the laparoscopic procedure. Age, gender, etiology, imaging findings, amylase level, complications due to pancreatitis, functional insufficiency, and history of CP were assessed in these patients.RESULTS: Nine laparoscopic and 37 open Frey procedures were analyzed. Of the 46 patients, 39 were male(85%) and seven were female(16%). The etiology of CP was alcohol in 32 patients(70%) and idiopathic in 14 patients(30%). Stones were found in 38 patients(83%). An inflammatory mass was found in five patients(11%). The time from diagnosis of CP to the Frey procedure was 39 ± 19(9-85) mo. The BMI of patients in the laparoscopic group was 20.4 ± 1.7(17.8-22.4) kg/m2 and was 20.6 ± 2.9(15.4-27.7) kg/m2 in the opengroup. Allpatientsrequired analgesic medication for abdominal pain. Frequent acute pancreatitis or severe abdominal pain due to acute exacerbation occurred in 20 patients(43%). Pre-operative complications due to pancreatitis were observed in 18 patients(39%). Pancreatic functional insufficiency was observed in 14 patients(30%). Two laparoscopic patients(2/9) were converted. In seven successful laparoscopic cases, the mean operative time was 323 ± 29(290-370) min. Estimated intra-operativeblood loss was 57 ± 14(40-80) m L. One patient had a postoperative complication, and no mortality was observed. Postoperative hospital stay was 7 ± 2(5-11) d. Multiple linear regression analysis of 37 open Frey procedures showed that an inflammatory mass(P < 0.001) and acute exacerbation(P < 0.001) were risk factors for intra-operative blood loss. CONCLUSION: The laparoscopic Frey procedure for CP is feasible but only suitable in carefully selected patients.展开更多

Presently, shunt and disconnection are commonlyused for surgical treatment of portal hypertension. The aimof this study was conducted to analyze the results of a modi-fied Sugiura procedure for the management of 160 cirrhoticpatients with portal hypertension.METHODS: The results of a modified Sugiura procedurefor the treatment of 160 cirrhotic patients with portal hyper-tension from January 1991 to July 2002 were retrospectivelyanalyzed.RESULTS: The operative mortality for the procedure waszero. Postoperative intra-abdominal bleeding was noted in2 patients, drowned lung in 1, pneumonia in 1, and splenicvenous thrombosis in 4. Of the 160 patients, 157 (98%)were followed up from 6 months to 11.5 years. Of the 157patients, only one died of hepatic coma 6 years after opera-tion, and 3 of rebleeding. The absolute and relative survivalrates were 97.5% (156/160) and 99% (159/160), respective-ly. The absolute and relative occurrence rates of hepatic co-ma were 2.5% (4/160) and 0.6% (1/157), respectively. Theabsolute and relative occurrence rates of rebleeding were3.8% (6/160) and 1.9% (3/157) , respectively. In 96 of 116Child B patients (82.8%), liver function improved frompreoperative class B to A 3 months after operation. Sixty-five patients were subjected to gastroscopy and 22 patients,esophageal barium photography 6 months after operation.Gastro-esophageal varices disappeared in 56 patients(64.4%, 56/87), obviously improved in 30 (34.5%, 30/87),and unchanged in 1 (1.2%, 1/87). The occurrence rate ofportal hypertensive gastropathy (PHG) was 13.9% (9/65).CONCLUSION: Our results showed that the modifiedSugiura procedure is effective in the treatment of portal hy-pertension, with a low rate of operative complication,bleeding recurrence, and hepatic coma.展开更多

The effective rate of internal drain-age was significantly lower than that of cyst resection(3/10 vs 45/49, X^2=20. 94, P【0.001). The re-op-eration rate and incidence of carcinoma of internaldrainage were higher than those of cyst resection (5/10 vs 3/49, X^2=13. 64, P【0. 001 and 3/10 vs 3/49,X^2=5. 18, P【0. 025). The reoperation rate of e-mergency surgery was higher than that of selectiveoperation (8/10 vs 6/56, X^2=24. 37, P【0.001).Conclusions: External drainage should be the first-aid measure and the therapy of choice on emergencybasis. Internal drainage should never be attempted.Cyst resection with Roux-en-Y hepaticojejunostomy isrecommended as the treatment of choice in selectiveoperation.展开更多

Analysis of post-operative complications, rate and time of recurrence and factors influencing the choice of the procedure for recurrent disease was conducted. Continuous variables were expressed as the median with interquartile range(IQR). Statistical analysis was carried out using the Fisher exact test.RESULTS: Median age at the time of surgery was 76 years(IQR: 71-81.5) and there were 38 females and 2 males. The median duration of symptoms was 6 mo(IQR: 3.5-12) and majority of patients presented electively whereas four patients presented in the emergency department with irreducible rectal prolapse. The median length of prolapse was 5 cm(IQR: 5-7), median operative time was 100 min(IQR: 85-120) and median post-operative stay was 4 d(IQR: 3-6). Approximately16% of the patients suffered minor complications such as- urinary retention, delayed defaecation and infected haematoma. One patient died constituting postoperative mortality of 2.5%. Median follow-up was 6.5 mo(IQR: 2.15-16). Overall recurrence rate was 28%(n = 12). Recurrence rate for patients undergoing an urgent Delorme's procedure who presented as an emergency was higher(75.0%) compared to those treated electively(20.5%), P value 0.034. Median time interval from surgery to the development of recurrence was 16 mo(IQR: 5-30). There were three patients who developed an early recurrence, within two weeks of the initial procedure. The management of the recurrent prolapse was as follows: No further intervention(n = 1), repeat Delorme's procedure(n = 3), Altemeier's procedure(n = 5) and rectopexy with faecal diversion(n = 3). One patient was lost during follow up.CONCLUSION: Delorme's procedure is a suitable treatment for rectal prolapse due to low morbidity and mortality and acceptable rate of recurrence. The management of the recurrent rectal prolapse is often restricted to the pelvic approach by the same patientrelated factors that influenced the choice of the initial operation, i.e., Delorme's procedure. Early recurrence developing within days or weeks often represents a technical failure and may require abdominal rectopexy with faecal diversion.展开更多

文摘Background: Cervical Intraepithelial neoplasia treatments have become essential interventions to manage cervical lesions. Majority of the recipients of these treatments are women within the reproductive age group, who according to literature may be at risk of adverse pregnancy outcomes. This pilot study is part of a study investigating adverse pregnancy outcomes among women who received Cryotherapy, Thermal ablation and Loop Electrosurgical Excision Procedure compared to the untreated women in Zambia. Materials and Methods: This descriptive study analyzed records of 886 (n = 443 treated and n = 443 untreated) women aged 15 - 49 years. The women were either screened with Visual Inspection with Acetic Acid or treated for Cervical Intraepithelial neoplasia at the Adult Infectious Disease Centre between January 2010 and December 2020. Women meeting the criteria were identified using the Visual Inspection with Acetic Acid screening records and telephone interviews to obtain the adverse pregnancy outcome experienced. Data were analysed using STATA version 16 to determine the prevalence and obtain frequency distribution of outcomes of interest. Univariate and multivariable binary logistic regression estimated odds of adverse pregnancy outcomes across the three treatments. Results: The respondents were aged 15 to 49 years. Adverse pregnancy outcomes were observed to be more prevalent in the treatment group (18.5%) compared to the untreated group (5.4%). Normal pregnancy outcomes were lower in the treated (46.3%;n = 443) than the untreated (53.7%;n = 443). The treated group accounted for the majority of abortions (85.2%), prolonged labour (85.7%) and low birth weight (80%), whereas, the untreated accounted for the majority of still births (72.7%). Women treated with cryotherapy (aOR = 2.43, 95% CI = 1.32 - 4.49, p = 0.004), thermal ablation (aOR = 6.37, 95% CI = 0.99 - 41.2, p = 0.052) and Loop Electrosurgical Excision Procedure (aOR = 9.67, 95% CI = 2.17 - 43.1, p = 0.003) had two-, six- and ten-times higher odds of adverse pregnancy outcomes respectively, relative to women who required no treatment. Conclusion: Adverse pregnancy outcomes are prevalent among women who have received treatment in Zambia. The findings indicate that treating Cervical Intraepithelial Neoplasia has been linked to higher chances of experiencing abortion, delivering low birth weight babies and enduring prolonged labor that may result in a caesarean section delivery. Cervical neoplasia treatments, particularly Loop Electrosurgical Excision Procedure, are associated with significantly increased odds of adverse pregnancy outcomes. It is essential to include information about prior Cervical Intraepithelial neoplasia treatment outcomes in obstetric care.

文摘Objective:To compare the efficacy of anal adenectomy with virtual hanging wire and anal fistulotomy in the treatment of low anal fistula in infants and children.Methods:60 children with low anal fistula who were admitted to our hospital from October 2021 to March 2022 and met the inclusion criteria were randomly divided into two groups of 30 cases each;the treatment group was treated with anal adenectomy and virtual hanging wire surgery,and the control group was treated with anal fistula resection.The clinical efficacy after treatment was compared.Results:The total effective rate of both groups was 96.67%and the difference between the two groups was not statistically significant(P>0.05).The postoperative pain score of the treatment group was lower than that of the control group(P<0.05).The length of hospitalization and healing time of the treatment group was lower than that of the control group(P<0.05).The anal function of the patients in both groups was normal,and there was no adverse reaction.Conclusion:Anal gland excision and virtual hanging surgery for the treatment of low anal fistula in infants and children have the advantages of mild pain,reduced length of hospitalization,short healing time,and better patient experience as compared to anal fistula excision.
文摘To ensure the security of resource and intelligence sharing in 6G,blockchain has been widely adopted in wireless communications and applications.Although blockchain can ensure the traceability and non-tamperability of data in the concatenated blocks,it cannot guarantee the honest behaviors of users in the application before the generation of transactions.Thus,additional technologies are required to ensure that the source of blockchain data is reliable.In this paper,the detailed procedure is designed for the application-oriented task validation in the blockchainenhanced computing resource sharing and transactions in ultra dense networks(UDN).The corresponding queuing model is built and analyzed with the consideration of the wireless re-transmission and the probability of malicious deception by users.Based on the analysis results,the UDN deployment is optimized to save network cost while ensuring latency performance.Numerical results verify our analysis,and the optimized system deployment including the number and service capacities of both base stations and mobile edge computing(MEC)servers are also given with various system settings.
文摘BACKGROUND Transmission of severe acute respiratory syndrome coronavirus 2 can occur during aerosol generating procedures.Several steps in spinal fusion may aerosolize blood but little data exists to quantify the risk this may confer upon surgeons.Aerosolized particles containing infectious coronavirus are typically 0.5-8.0μm.AIM To measure the generation of aerosols during spinal fusion using a handheld optical particle sizer(OPS).METHODS We quantified airborne particle counts during five posterior spinal instrumentation and fusions(9/22/2020-10/15/2020)using an OPS near the surgical field.Data were analyzed by 3 particle size groups:0.3-0.5μm/m^(3),1.0-5.0μm/m^(3),and 10.0μm/m^(3).We used hierarchical logistic regression to model the odds of a spike in aerosolized particle counts based on the step in progress.A spike was defined as a>3 standard deviation increase from average baseline levels.RESULTS Upon univariate analysis,bovie(P<0.0001),high speed pneumatic burring(P=0.009),and ultrasonic bone scalpel(P=0.002)were associated with increased 0.3-0.5μm/m^(3)particle counts relative to baseline.Bovie(P<0.0001)and burring(P<0.0001)were also associated with increased 1-5μm/m^(3)and 10μm/m^(3)particle counts.Pedicle drilling was not associated with increased particle counts in any of the size ranges measured.Our logistic regression model demonstrated that bovie(OR=10.2,P<0.001),burring(OR=10.9,P<0.001),and bone scalpel(OR=5.9,P<0.001)had higher odds of a spike in 0.3-0.5μm/m^(3)particle counts.Bovie(OR=2.6,P<0.001),burring(OR=5.8,P<0.001),and bone scalpel(OR=4.3,P=0.005)had higher odds of a spike in 1-5μm/m^(3)particle counts.Bovie(OR=0.3,P<0.001)and drilling(OR=0.2,P=0.011)had significantly lower odds of a spike in 10μm/m^(3)particle counts relative to baseline.CONCLUSION Several steps in spinal fusion are associated with increased airborne particle counts in the aerosol size range.Further research is warranted to determine if such particles have the potential to contain infectious viruses.Previous research has shown that electrocautery smoke may be an inhalation hazard for surgeons but here we show that usage of the bone scalpel and high-speed burr also have the potential to aerosolize blood.

文摘BACKGROUND Rotationplasty is often performed for malignant tumors,but type BIIIb rotationplasty is rarely reported,and there needs to be more evidence of the procedure and treatment.The purpose of this case study was to report a new direction in the use of type BIIIb rotationplasty in treating patients with limb salvage and longterm non-healing infections.CASE SUMMARY Case 1:A 47-year-old man underwent radiotherapy for hemangioendothelioma in his left thigh,resulting in a femoral fracture.Despite the use of plates,intramedullary nailing,and external fixators,the femoral bone failed to unite due to infectious nonunion.Multiple operations were unable to control the infection,leaving the patient immobile.We performed a modified tibia-pelvic-constrained hip rotationplasty,utilizing a constrained prosthetic hip between the tibia and pelvis following a femur resection.Two years post-surgery,the patient was able to walk with the prosthetic device without any signs of recurring infection.The corresponding functional scores were 72 points for the Musculoskeletal Tumor Society(MSTS),53 for the Functional Mobility Assessment(FMA),93 for the Toronto Extremity Salvage Score(TESS),and 56 for the MOS 36-item short form health survey(SF-36).Case 2:A 59-year-old woman presented with liposarcoma in her left thigh.Magnetic resonance imaging revealed tumors in the medial,anterior,and posterior femur muscles,encircling the femoral vessels and nerves.Fortunately,there were no symptoms of sciatic dysfunction,and the tumor had not invaded the sciatic nucleus.After one year of follow-up,the patient expressed satisfaction with limb preservation post-type BIIIb rotationplasty.The corresponding functional scores were 63 points for the MSTS,47 for the FMA,88 for the TESS,and 52 for the SF-36.CONCLUSION Our study suggests that type BIIIb rotationplasty may be an alternative to amputation in patients with incurable infections.For malignant tumors of the lower extremities without invasion of the sciatic nerve,type BIIIb rotationplasty remains an excellent alternative to amputation.This surgical method may prevent amputation,improve functional outcomes,and facilitate biological reconstruction.
文摘Traditional Chinese medicine breast massage,also known as breast Tuina or manual expression of breast milk,is a technique of using certain manipulations to act on specific positions or acupoints of the breast to promote blood and lymphatic circulation of breast and facilitate the discharge of stagnant milk.This technique is widely used in China to treat breastfeeding problems such as breast engorgement,mastitis,and postpartum hypogalactia.In this article,we introduce the definition and standardization process of breast massage,elaborate the operating procedures of breast massage in detail,and summarize and discuss the current situation of its clinical application,so as to provide a reference for its wide application and in‑depth research.

文摘Background:The study aimed to assess the efficacy and safety of dinoprostone vaginal insert in labor induction following optimization of standard operating procedure(SOP)and to discover independent predictors of vaginal delivery.Methods:This study comprised 551 pregnant women who required cervical ripening with dinoprostone before induction of labor.Using univariate and multivariate analyses,independent predictors of vaginal delivery were identified.Results:443 of the 551 women(80.4%)gave birth vaginally.Vaginal delivery was predicted by maternal age(24-30 vs.<24,P<0.001;30-35 vs.<24,P=0.03),gestational age(P=0.005),birth weight(P<0.001),parity(P=0.001),pre-pregnancy BMI(P<0.001),premature rupture of membranes(P=0.001),meconium-stained amniotic fluid(P<0.001),fundal height(P<0.001)and the Bishop score(P<0.001).None of the women exhibited severe postpartum hemorrhage.Conclusions:The maternal age,gestational age,birth weight,parity,body mass index,premature membrane rupture,amniotic fluid contamination,fundal height,and the Bishop score were independent predictors of vaginal delivery.These may guide the clinical use of dinoprostone for induction of labor.
文摘Aim: This study aimed to assess and compare the functional and anatomical results of pars plana vitrectomy (PPV) alone versus PPV combined with scleral buckling (SB), and lens-sparing versus phaco-procedures for treating rhegmatogenous retinal detachment. Methods: A comprehensive literature search was performed using the Web of Science, MEDLINE, EMBASE, and Cochrane Library databases to retrieve comparative studies. The main objective was to assess the BCVA, while reattachment rates and ocular adverse events were considered secondary measures. Rev Manager software was used for statistical analysis. Results: The literature search identified 10 articles comprising 1518 eyes, with 682 eyes in the PPV group, 193 eyes in the lens-sparing versus phaco-procedure group, and 643 eyes in the combined PPV and SB surgery group. Quality assessment revealed a low risk of bias in most domains. The meta-analysis results revealed a significant difference in postoperative BCVA between the PPV and PPV combined with SB groups (WMD = −0.17, 95% CI [0.27, 0.07], p = 0.001). The primary reattachment rates were 82.80% for PPV alone and 87.52% for PPV combined with SB (p = 0.34). The final reattachment rates did not differ significantly between PPV and PPV combined with SB (99% vs. 99.8%;RR = 1.00, 95% CI [1.01, 0.99], p = 0.96). PPV alone demonstrated a significantly reduced risk of macular edema compared to PPV combined with scleral buckling (9.9% vs. 23%;p = 0.006). The incidences of macular hole development (p = 0.46), recurrent retinal detachment (p = 0.27), proliferative vitreoretinopathy development (p = 0.48), epiretinal membrane proliferation (p = 0.77), and limited choroidal hemorrhage (p = 0.69) were not significantly different between the two groups. Conclusions: These findings suggest that PPV alone may be a more effective treatment option in terms of visual acuity (VA) improvement, lower risk of macular edema and cataract development. However, there was no significant difference in VA improvement or complication rates between the lens-sparing and phaco-procedure groups. .
文摘AIM: To compare the clinical efficacies of two surgical procedures for hemorrhoid rectal prolapse with outlet obstruction-induced constipation.METHODS: One hundred eight inpatients who underwent surgery for outlet obstructive constipation caused by internal rectal prolapse and circumferential hemorrhoids at the First Affiliated Hospital of Xinjiang Medical University from June 2012 to June 2013 were prospectively included in the study.The patients with rectal prolapse hemorrhoids with outlet obstructioninduced constipation were randomly divided into two groups to undergo either a procedure for prolapse and hemorrhoids(PPH)(n = 54) or conventional surgery(n = 54; control group).Short-term(operative time,postoperative hospital stay,postoperative urinary retention,postoperative perianal edema,and postoperative pain) and long-term(postoperative anal stenosis,postoperative sensory anal incontinence,postoperative recurrence,and postoperative difficulty in defecation) clinical effects were compared between the two groups.The short- and long-term efficacies of the two procedures were determined.RESULTS: In terms of short-term clinical effects,operative time and postoperative hospital stay were significantly shorter in the PPH group than in the control group(24.36 ± 5.16 min vs 44.27 ± 6.57 min,2.1 ± 1.4 d vs 3.6 ± 2.3 d,both P < 0.01).The incidence of postoperative urinary retention was higher in the PPH group than in the control group,but the difference was not statistically significant(48.15% vs 37.04%).Theincidence of perianal edema was significantly lower in the PPH group(11.11% vs 42.60%,P < 0.05).The visual analogue scale scores at 24 h after surgery,first defecation,and one week after surgery were significantly lower in the PPH group(2.9 ± 0.9 vs 8.3 ± 1.1,2.0 ± 0.5 vs 6.5 ± 0.8,and 1.7 ± 0.5 vs 5.0 ± 0.7,respectively,all P < 0.01).With regard to long-term clinical effects,the incidence of anal stenosis was lower in the PPH group than in the control group,but the difference was not significant(1.85% vs 5.56%).The incidence of sensory anal incontinence was significantly lower in the PPH group(3.70% vs 12.96%,P < 0.05).The incidences of recurrent internal rectal prolapse and difficulty in defecation were lower in the PPH group than in the control group,but the differences were not significant(11.11% vs 16.67% and 12.96% vs 24.07%,respectively).CONCLUSION: PPH is superior to the traditional surgery in the management of outlet obstructive constipation caused by internal rectal prolapse with circumferential hemorrhoids.
文摘Endoscopic submucosal dissection (ESD) is efficient for en bloc resection of large colorectal tumors. However, it has several technical difficulties, because the wall of the colon is thin and due to the winding nature of the colon. The main complications of ESD comprise postoperative perforation and hemorrhage, similar to endoscopic mucosal resection (EMR). In particular, the rate of perforation in ESD is higher than that in EMR. Perforation of the colon can cause fatal peritonitis. Endoscopic clipping is reported to be an efficient therapy for perforation. Most cases with perforation are treated conservatively without urgent surgical intervention. However, the rate of postoperative hemorrhage in ESD is similar to that in EMR. Endoscopic therapy including endoscopic clipping is performed and most of the cases are treated conservatively without blood transfusion. In blood examination, some degree of inflammation is detected after ESD. For the standardization of ESD, it is most important to decrease the rate of perforation. Adopting a safe strategy for ESD and a suitable choice of knife are both important waysof preventing perforation. Moreover, appropriate training and increasing experience can improve the endoscopic technique and can decrease the rate of perforation. In this review, we describe safe procedures in ESD to prevent complications, the complications of ESD and their management.
文摘AIM: To share our experience regarding the laparoscopic Frey procedure for chronic pancreatitis(CP) and patient selection.METHODS: All consecutive patients undergoingduodenum-preserving pancreatic head resection from July 2013 to July 2014 were reviewed and those undergoing the Frey procedure for CP were included in this study. Data on age, gender, body mass index(BMI), American Society of Anesthesiologists score, imaging findings, inflammatory index(white blood cells, interleukin(IL)-6, and C-reaction protein), visual analogue score score during hospitalization and outpatient visit, history of CP, operative time, estimated blood loss, and postoperative data(postoperative mortality and morbidity, postoperative length of hospital stay) were obtained for patients undergoing laparoscopic surgery. The open surgery cases in this study were analyzed for risk factors related to extensive bleeding, which was the major reason for conversion during the laparoscopic procedure. Age, gender, etiology, imaging findings, amylase level, complications due to pancreatitis, functional insufficiency, and history of CP were assessed in these patients.RESULTS: Nine laparoscopic and 37 open Frey procedures were analyzed. Of the 46 patients, 39 were male(85%) and seven were female(16%). The etiology of CP was alcohol in 32 patients(70%) and idiopathic in 14 patients(30%). Stones were found in 38 patients(83%). An inflammatory mass was found in five patients(11%). The time from diagnosis of CP to the Frey procedure was 39 ± 19(9-85) mo. The BMI of patients in the laparoscopic group was 20.4 ± 1.7(17.8-22.4) kg/m2 and was 20.6 ± 2.9(15.4-27.7) kg/m2 in the opengroup. Allpatientsrequired analgesic medication for abdominal pain. Frequent acute pancreatitis or severe abdominal pain due to acute exacerbation occurred in 20 patients(43%). Pre-operative complications due to pancreatitis were observed in 18 patients(39%). Pancreatic functional insufficiency was observed in 14 patients(30%). Two laparoscopic patients(2/9) were converted. In seven successful laparoscopic cases, the mean operative time was 323 ± 29(290-370) min. Estimated intra-operativeblood loss was 57 ± 14(40-80) m L. One patient had a postoperative complication, and no mortality was observed. Postoperative hospital stay was 7 ± 2(5-11) d. Multiple linear regression analysis of 37 open Frey procedures showed that an inflammatory mass(P < 0.001) and acute exacerbation(P < 0.001) were risk factors for intra-operative blood loss. CONCLUSION: The laparoscopic Frey procedure for CP is feasible but only suitable in carefully selected patients.
文摘BACKGROUND: Portal hypertension is a common diseasewith a high mortality and serious effect on the life quality ofpatients. Presently, shunt and disconnection are commonlyused for surgical treatment of portal hypertension. The aimof this study was conducted to analyze the results of a modi-fied Sugiura procedure for the management of 160 cirrhoticpatients with portal hypertension.METHODS: The results of a modified Sugiura procedurefor the treatment of 160 cirrhotic patients with portal hyper-tension from January 1991 to July 2002 were retrospectivelyanalyzed.RESULTS: The operative mortality for the procedure waszero. Postoperative intra-abdominal bleeding was noted in2 patients, drowned lung in 1, pneumonia in 1, and splenicvenous thrombosis in 4. Of the 160 patients, 157 (98%)were followed up from 6 months to 11.5 years. Of the 157patients, only one died of hepatic coma 6 years after opera-tion, and 3 of rebleeding. The absolute and relative survivalrates were 97.5% (156/160) and 99% (159/160), respective-ly. The absolute and relative occurrence rates of hepatic co-ma were 2.5% (4/160) and 0.6% (1/157), respectively. Theabsolute and relative occurrence rates of rebleeding were3.8% (6/160) and 1.9% (3/157) , respectively. In 96 of 116Child B patients (82.8%), liver function improved frompreoperative class B to A 3 months after operation. Sixty-five patients were subjected to gastroscopy and 22 patients,esophageal barium photography 6 months after operation.Gastro-esophageal varices disappeared in 56 patients(64.4%, 56/87), obviously improved in 30 (34.5%, 30/87),and unchanged in 1 (1.2%, 1/87). The occurrence rate ofportal hypertensive gastropathy (PHG) was 13.9% (9/65).CONCLUSION: Our results showed that the modifiedSugiura procedure is effective in the treatment of portal hy-pertension, with a low rate of operative complication,bleeding recurrence, and hepatic coma.
文摘Objective: To evaluate the procedures and timing ofoperation as well as long-term postoperative effect ofcongenital choledochal cysts (CCC) in adults.Methods: The procedures and timing of operation,effective rate, re-operation rate and incidence of car-cinoma after operation for 70 adult patients withCCC from January 1980 to June 1999 were analyzedretrospectively.Results: The re-operation rate of external drainagewas 86% (6/7). The effective rate of internal drain-age was significantly lower than that of cyst resection(3/10 vs 45/49, X^2=20. 94, P【0.001). The re-op-eration rate and incidence of carcinoma of internaldrainage were higher than those of cyst resection (5/10 vs 3/49, X^2=13. 64, P【0. 001 and 3/10 vs 3/49,X^2=5. 18, P【0. 025). The reoperation rate of e-mergency surgery was higher than that of selectiveoperation (8/10 vs 6/56, X^2=24. 37, P【0.001).Conclusions: External drainage should be the first-aid measure and the therapy of choice on emergencybasis. Internal drainage should never be attempted.Cyst resection with Roux-en-Y hepaticojejunostomy isrecommended as the treatment of choice in selectiveoperation.
文摘BACKGROUND:The Frey procedure(FP)is the treatment of choice for symptomatic chronic pancreatitis(CP).In cases of biliary stricture,biliary derivation can be performed by choledochoduodenostomy,Roux-en-Y choledochojejunostomy or,more recently,reinsertion of the common bile duct(CBD)into the resection cavity.The objective of the present study was to evaluate the outcomes associated with each of these three types of biliary derivation.METHODS:We retrospectively analyzed demographic,CPrelated,surgical and follow-up data for patients having undergone FP for CP with biliary derivation between 2004and 2012 in our university medical center.The primary efficacy endpoint was the rate of CBD stricture recurrence.The secondary endpoints were surgical parameters,postoperative complications,postoperative follow-up and the presence of risk factors for secondary CBD stricture.RESULTS:Eighty patients underwent surgery for CP during the study period.Of these,15 patients received biliary derivation with the FP.Eight of the FPs(53.3%)were combined with choledochoduodenostomy,4(26.7%)with choledochojejunostomy and 3(20.0%)with reinsertion of the CBD into the resection cavity.The mean operating time was 390minutes.Eleven complications(73.3%)were recorded,including one major complication(6.7%)that necessitated radiologicallyguided drainage of an abdominal collection.The mean(range)length of stay was 17 days(8-28)and the median(range)follow-up time was 35.2 months(7.2-95.4).Two patients presented stricture after CBD reinsertion into the resection cavity;one was treated with radiologically-guided dilatation and the other underwent revisional Roux-en-Y choledochojejunostomy.Three patients presented alkaline reflux gastritis(37.5%),one(12.5%)cholangitis and one CBD stricture after FP with choledochoduodenostomy.No risk factors for secondary CBD stricture were identified.CONCLUSIONS:As part of a biliary derivation,the FP gave good results.We did not observe any complications specifically related to surgical treatment of the biliary tract.However,CBD reinsertion into the resection cavity appeared to be associated with a higher stricture recurrence rate.In our experience,choledochojejunostomy remains the"gold standard"for the surgical treatment for CBD strictures.
文摘AIM: To report our experience with perineal repair(Delorme's procedure) of rectal prolapse with particular focus on treatment of the recurrence.METHODS: Clinical records of 40 patients who underwent Delorme's procedure between 2003 and 2014 were reviewed to obtain the following data: Gender; duration of symptoms, length of prolapse, operation time, ASA grade, length of post-operative stay, procedure-related complications, development and treatment of recurrent prolapse. Analysis of post-operative complications, rate and time of recurrence and factors influencing the choice of the procedure for recurrent disease was conducted. Continuous variables were expressed as the median with interquartile range(IQR). Statistical analysis was carried out using the Fisher exact test.RESULTS: Median age at the time of surgery was 76 years(IQR: 71-81.5) and there were 38 females and 2 males. The median duration of symptoms was 6 mo(IQR: 3.5-12) and majority of patients presented electively whereas four patients presented in the emergency department with irreducible rectal prolapse. The median length of prolapse was 5 cm(IQR: 5-7), median operative time was 100 min(IQR: 85-120) and median post-operative stay was 4 d(IQR: 3-6). Approximately16% of the patients suffered minor complications such as- urinary retention, delayed defaecation and infected haematoma. One patient died constituting postoperative mortality of 2.5%. Median follow-up was 6.5 mo(IQR: 2.15-16). Overall recurrence rate was 28%(n = 12). Recurrence rate for patients undergoing an urgent Delorme's procedure who presented as an emergency was higher(75.0%) compared to those treated electively(20.5%), P value 0.034. Median time interval from surgery to the development of recurrence was 16 mo(IQR: 5-30). There were three patients who developed an early recurrence, within two weeks of the initial procedure. The management of the recurrent prolapse was as follows: No further intervention(n = 1), repeat Delorme's procedure(n = 3), Altemeier's procedure(n = 5) and rectopexy with faecal diversion(n = 3). One patient was lost during follow up.CONCLUSION: Delorme's procedure is a suitable treatment for rectal prolapse due to low morbidity and mortality and acceptable rate of recurrence. The management of the recurrent rectal prolapse is often restricted to the pelvic approach by the same patientrelated factors that influenced the choice of the initial operation, i.e., Delorme's procedure. Early recurrence developing within days or weeks often represents a technical failure and may require abdominal rectopexy with faecal diversion.
