Open surgery:Still a great option to treat patients with posttraumatic arteriovenous fistulas:A case report

BACKGROUND In the modern era of endovascular surgery percutaneous interventions are being widely used to treat a number of vascular disorders including arteriovenous fistulas(AVF).Still,patients with hostile anatomy or complicated cases such as large post-traumatic AVFs may be successfully treated using conventional vascular surgery.CASE SUMMARY This paper presents state-of-the-art treatment options in subjects with posttraumatic AVFs and a case-report of a successful open surgical approach in a patient with a 25 year old history of a post-traumatic AVF between the common femoral artery and common femoral vein.CONCLUSION Open surgery is still a great option to treat patients with post-traumatic arteriovenous fistulas with hostile anatomy or in complicated cases.Concomitant conditions and complications should be addressed promptly.

Evolving thoracic surgery: from open surgery to single port thoracoscopic surgery and future robotic

Thoracic Surgery is a continuous evolving specialty. In the past, thoracic surgeons had to make large incisions in order to operate any pathology inside the chest. This often meant big, painful and ugly scars and long recovery times after surgery. But he history of thoracic surgery changed since the begining of video-assisted thoracoscoDic surgery （VATg3

Laparoscopic vs.open surgery for gastrointestinal stromal tumors of esophagogastric junction:A multicenter,retrospective cohort analysis with propensity score weighting

Objective:Laparoscopic resection is increasingly performed for gastrointestinal stromal tumors(GISTs).However,the laparoscopic approach for GISTs located in the esophagogastric junction(EGJ-GIST)is surgically challenging.This study compares the efficacy of laparoscopic surgery and the open procedure for EGJ-GIST through the propensity score weighting(PSW)method.Methods:Between April 2006 and April 2018,1,824 surgical patients were diagnosed with primary gastric GIST at four medical centers in South China.Of these patients,228 were identified as EGJ-GISTs and retrospectively reviewed clinicopathological characteristics,operative information,and long-term outcomes.PSW was used to create the balanced cohorts.Results:PSW was carried out in laparoscopic and open-surgery cohorts according to year of surgery,sex,age,body mass index(BMI),tumor size,mitotic rates and recurrence risk.After PSW,438 patients consisting of 213 laparoscopic(L group)and 225 open surgery(O group)patients were enrolled.After PSW,the following measures in the L group were superior to those in the O group:median operative time[interquartile range(IQR)]:100.0(64.5-141.5)vs.149.0(104.0-197.5)min,P<0.001;median blood loss(IQR):30.0(10.0-50.0)vs.50.0(20.0-100.0)mL,P=0.002;median time to liquid intake(IQR):3.0(2.0-4.0)vs.4.0(3.0-5.0)d,P<0.001;median hospital stay(IQR):6.0(4.0-8.0)vs.7.0(5.0-12.0)d,P<0.001;and postoperative complications(10.3%vs.22.7%,P=0.001).The median follow-up was 55(range,2-153)months in the entire cohort.No significant differences were detected in either relapse-free survival(RFS)[hazard ratio(HR):0.372,95%confidence interval(95%CI):0.072-1.910,P=0.236]or overall survival(OS)(HR:0.400,95%CI:0.119-1.343,P=0.138)between the two groups.Conclusions:Laparoscopic surgery for EGJ-GIST is associated with the advantages of shorter operative time,reduced blood loss,shorter time to liquid intake,and shorter length of stay,all without compromising postoperative outcomes and long-term survival.

Open surgery in the era of minimally invasive surgery

The benefits and popularity of minimally invasive surgery are undeniable around the globe.However,open surgery is necessary and learning open surgery skills is still a necessity.Open surgery allows for better exposure to the surgical field and provides tactile sensation to facilitate the stereo visual assessment to precisely remove the lesion.Open surgery is still the key to surgical training,and the skills learned from open surgeries remain crucial for unforeseen circumstances and certain conditions like emergencies,challenge cases,or patients with compromised status.

Clinical effect of laparoscopic radical resection of colorectal cancer based on propensity score matching

BACKGROUND The incidence of colorectal cancer(CRC)is increasing annually.Laparoscopic radical resection of CRC is a minimally invasive procedure preferred in clinical practice.AIM To investigate the clinical effect of laparoscopic radical resection of CRC on the basis of propensity score matching(PSM).METHODS The clinical data of 100 patients who received inpatient treatment for CRC at Changde Hospital,Xiangya School of Medicine,Central South University(The First People’s Hospital of Changde City)were analyzed retrospectively.The control group included patients who underwent open surgery(n=43),and those who underwent laparoscopic surgery formed the observation group(n=57).The baseline information of both groups was equipoised using 1×1 PSM.Differences in the perioperative parameters,inflammatory response,immune function,degree of pain,and physical status between the groups were analyzed.RESULTS Thirty patients from both groups were successfully matched.After PSM,baseline data showed no statistically significant differences between the groups:(1)Periop-erative parameters:The observation group had a longer surgery time,less intra-operative blood loss,earlier first ambulation and first anal exhaust times,and shorter gastric tube indwelling time than the control group;(2)Inflammatory response:24 h after surgery,the levels of interleukin-6(IL-6),C-reactive protein(CRP),and tumor necrosis factor-α(TNF-α)between groups were higher than preoperatively.IL-6,CRP,and TNF-αlevels in the observation group were lower than in the control group;(3)Immune function:At 24 h after surgery,counts of CD4-positive T-lymphocytes(CD4+)and CD4+/CD8-positive T-lymphocytes(CD8+)in both groups were lower than those before surgery,whereas CD8+was higher than that before surgery.At 24 h after surgery,both CD4+counts and CD4+/CD8+in the observation group were higher than those in the control group,whereas CD8+counts were lower;(4)Degree of pain:The visual analog scale scores in the observation group were lower than those in the control group at 24 and 72 h after surgery;and(5)Physical status:One month after surgery,the Karnofsky performance score in the observation group was higher than that in the control group.CONCLUSION Laparoscopic radical resection of CRC has significant benefits,such as reducing postoperative pain and postoperative inflammatory response,avoiding excessive immune inhibition,and contributing to postoperative recovery.

Postoperative ileus in colorectal surgery:is there any difference between laparoscopic and open surgery?

Background:Postoperative ileus is a major complication of patients undergoing abdominal surgery.The purpose of this study was to determine the effects of operative time and the method of surgery on postoperative ileus.Methods:After institutional review board approval,121 patients were studied in two groups.Group 1 consisted of 86 patients with colorectal cancers and Group 2 included 35 patients with diverticulitis.Various surgical procedures were performed in both groups.In all patients,the nasogastric(NG)tube was removed after termination of surgery.Clear liquids were offered commencing on the first postoperative day,followed by a regular diet as tolerated.GI-1 was the postoperative time to toleration of clear liquids,whereas GI-2 was the postoperative time to first bowel movement or flatus and toleration of a regular diet.Statistical analysis was performed using a linear regression model by disease with the first bowel movement or flatus as the dependent variable and operative time and category as explanatory variables.Results:Vomiting after oral feeding occurred in 18(20.9%)patients with cancer and in 7(20.0%)patients with diverticular disease.An NG tube was reinserted in 13(15.1%)patients in the cancer group and in 3(8.6%)patients in the diverticular disease group.In patients with cancer,the duration of operation was associated with GI-2(P=0.011),whereas in patients with diverticulitis,the duration of operation was associated with GI-1(P=0.001)and GI-2(P=0.044).In the diverticulitis group,a significant relationship was found between GI-2 and operative category(P=0.03).Conclusion:Longer operations led to more prolonged postoperative ileus after both laparoscopy and laparotomy,regardless of malignant or benign pathology.In anticipation of and/or following longer operations,surgeons should consider measures to shorten postoperative ileus.

Application of laparoscopic surgery in gallbladder carcinoma

Gallbladder carcinoma(GC)is a rare type of cancer of the digestive system,with an incidence that varies by region.Surgery plays a primary role in the comprehensive treatment of GC and is the only known cure.Compared with traditional open surgery,laparoscopic surgery has the advantages of convenient operation and magnified field of view.Laparoscopic surgery has been successful in many fields,including gastrointestinal medicine and gynecology.The gallbladder was one of the first organs to be treated by laparoscopic surgery,and laparoscopic cholecystectomy has become the gold standard surgical treatment for benign gallbladder diseases.However,the safety and feasibility of laparoscopic surgery for patients with GC remain controversial.Over the past several decades,research has focused on laparoscopic surgery for GC.The disadvantages of laparoscopic surgery include a high incidence of gallbladder perforation,possible port site metastasis,and potential tumor seeding.The advantages of laparoscopic surgery include less intraoperative blood loss,shorter postoperative hospital stay,and fewer complications.Nevertheless,studies have provided contrasting conclusions over time.In general,recent research has tended to support laparoscopic surgery.However,the application of laparoscopic surgery in GC is still in the exploratory stage.Here,we provide an overview of previous studies,with the aim of introducing the application of laparoscopy in GC.

Medium-term surgical outcomes and health-related quality of life after laparoscopic vs open colorectal cancer resection: SF-36 health survey questionnaire

BACKGROUND Previous studies that compared the postoperative health-related quality of life(HRQoL)outcomes after receiving laparoscopic resection(LR)or open resection(OR)in patients with colorectal cancer(CRC)have different conclusions.AIM To explore the medium-term effect of postoperative HRQoL in such patients.METHODS This study randomized 567 patients undergoing non-metastatic CRC surgery managed by one surgeon to the LR or OR groups.HRQoL was assessed during the preoperative period and 3,6,and 12 mo postoperative using a modified version of the 36-Item Short Form(SF-36)Health Survey questionnaire,emphasizing eight specific items.RESULTS This cohort randomly assigned 541 patients to receive LR(n=296)or OR(n=245)surgical procedures.More episodes of postoperative urinary tract infection(P<0.001),wound infection(P<0.001),and pneumonia(P=0.048)were encountered in the OR group.The results demonstrated that the LR group subjectively gained mildly better general health(P=0.045),moderately better physical activity(P=0.006),and significantly better social function recovery(P=0.0001)3 mo postoperatively.Only the aspect of social function recovery was claimed at 6 mo,with a significant advantage in the LR group(P=0.001).No clinical difference was found in HRQoL during the 12 mo.CONCLUSION Our results demonstrated that LR resulted in better outcomes,including intra-operative blood loss,surgery-related complications,course of recovery,and especially some health domains of HRQoL at least within 6 mo postoperatively.Patients should undergo LR if there is no contraindication.

Progression of Minimally Invasive Urological Surgery at Hôpital Général Idrissa Pouye in Dakar in 20 Years of Practice

Introduction: Open surgery is gradually being supplanted by minimally invasive surgical techniques worldwide. Our study aimed to describe the place of minimally invasive surgery at the Hôpital Général Idrissa Pouye (HOGIP) in Dakar. Materials and Methods: This is a descriptive cross-sectional study over a 20-years period from 1st June 2000 to 31st December 2021 in the urology department of HOGIP in Dakar. The list of all surgical procedures performed was computed. We evaluated the distribution of minimally invasive procedures (endoscopy, PCNL, laparoscopy) overall and over the years. We made calculations of proportions and statistical significance was considered for alpha = 0.05. Results: In 20 years, 14,855 surgical procedures were performed, of which 5344 (36%) were minimally invasive surgeries. The average age of men was 53.19 years (standard deviation: 21.77) vs 47.32 years (standard deviation: 18.43) for women. Minimally invasive procedures in the lower urinary tract accounted for 71.93% and involved 1033 cystoscopies (26.87%), 1020 Trans Urethral Resection of Prostate (TURP) (26.53%), 931 Direct Vision Internal Urethrotomy (DVIU) (24.21%, and 612 Trans Urethral Resection of the Bladder (TURB) (15.92%). In the upper urinary tract, 1461 (28.07%) minimally invasive procedures were performed, including PCNL in 193 cases (3.61%), laser endopyelotomy in 104 cases (1.95%), ureteroscopy in 486 cases (1.7%) and laparoscopy in 39 cases (0.46%). The proportion of minimally invasive surgery has gradually increased. Among the 5344 minimally invasive procedures, 333 (5.23%) were performed in 2000-2004 and 2332 (43.63%) in 2015-2019. Conclusion: Minimally invasive surgery represents an important part of the activity of the HOGIP urology department. Its development has improved over the years offering its advantages to the patients.

Psychosocial Factors Associated with Transfer Anxiety among Open Heart Surgery Patients Transferred from the Intensive Care Unit to the General Ward

Introduction: Patient’s transfer from the intensive care unit (ICU) to the general ward indicates their improving health status. However, the transfer produces anxiety when patients enter an unfamiliar environment with different care protocols and circumstances. Objectives: This study aimed to examine the level of ICU transfer anxiety among open heart surgery patients and determine the psychosocial factors associated with ICU transfer anxiety among open heart surgery patients. Methods: Data were collected in a cardiac center in Kathmandu City, Nepal among 95 open heart surgery patients within 24 hours of their transfer from an ICU to a general ward. The study used four self-reported questionnaires, namely the modified Mishel Uncertainty in Illness Scale for Adults, modified Brief COPE Inventory, Nurses’ Support Questionnaire, and State Anxiety Inventory. Results: Fifty-two patients (54.7%) had a high level of transfer anxiety. Spearman’s rank correlation showed that uncertainty in illness, coping, and nurses’ support were significantly related to transfer anxiety (p < 0.001). Conclusion: The results of this study suggest nurses to address uncertainty in illness of the patients, improve their coping abilities, and provide need-based nursing support to them during the transitional phase. Besides, clinicians and governmental agencies should contribute to implication of transitional guidelines, which can reduce transfer anxiety and promote health and recovery of the patients.

Role of laparoscopic and robotic liver resection compared to open surgery in elderly hepatocellular carcinoma patients: a systematic review and meta-analysis

Aim:This study aimed to compare mini-invasive liver resection(MILR)(laparoscopic/robotic approach)and open liver resection(OLR)for hepatocellular carcinoma(HCC)in elderly patients with regard to clinical and oncological outcomes through a comprehensive systematic review.Methods:The MEDLINE and Cochrane Library electronic databases were systematically searched from 2009 to December 2019 to identify relevant English written studies comparing MILR and OLR.The main endpoints were Child-Pugh score,serum total bilirubin level,comorbidity,presence/absence of cirrhosis,minor/major resection,challenge segment approach,operative time,estimated intraoperative blood loss,liver failure rate,morbidity according to the Clavien-Dindo classification,length of hospital stay(LOS),postoperative mortality,number of lesions,tumor size,readmission rate,recurrence rate and survival at 1,3 and 5 years after operation.Meta-analyses provided pooled relative risks and mean differences for these outcomes.Cut-off for"elderly age"was set at 65 years old.Results:Eight studies that evaluated 3051 patients who underwent liver resection for HCC,with 950 undergoing MILR and 2101 OLR,were included after the screening process.Blood loss,morbidity,and LOS showed statistical significance in favor of MILR.In particular,with respect to OLR,MILR decreased on average blood loss by 161.43 mL(95%CI:250.24-72.61),risk of morbidity by 42%(P<0.01),LOS by 4 days(95%CI:7-2),postoperative mortality risk by 47%(although not significantly,P=0.06).Major resections were significantly more common in the OLR group(P<0.0001).Recurrence,although not significant(P=0.06),must also be emphasized.The two surgical approaches were comparable with regard to the other outcomes investigated.Conclusion:Meta-analyses confirmed the advantages of MILR in terms of short perioperative outcomes,where it may promote the extension of liver resection to HCC patients with borderline liver function.MILR may be considered an important treatment option with significant benefits in the elderly and fragile patients.However,large well-designed prospective comparative studies or randomized controlled trials would be necessary to further confirm our conclusions.

Meta-analysis of the efficacy and safety of combined surgery in the management of eyes with coexisting cataract and open angle glaucoma

AIM： To conduct a systematic review and quantitative Meta-analysis of the efficacy and safety of combined surgery for the eyes with coexisting cataract and open angle glaucoma.METHODS： We performed a systematic search of the related literature in the Cochrane Library, PubM ed, EMBASE, Web of Science databases, CNKI, CBM and Wan Fang databases, with no limitations on language or publication date. The primary efficacy estimate was identified by weighted mean difference of the percentage of intraocular pressure reduction（IOPR%） from baseline to end-point, the percentage of number of glaucoma medications reduction from pre-to post-operation, and the secondary efficacy evaluations were performed by odds ratio（OR） and 95% confidence interval（CI） for complete and qualified success rate. Besides, ORs were applied to assess the tolerability of adverse incidents. Meta-analyses of fixed or random effect models were performed using Rev Man software 5.2 to gather the consequences. Heterogeneity was evaluated by Chi^2 test and the I^2 measure.RESULTS： Ten studies enrolling 3108 patients were included. The combined consequences indicated that both glaucoma and combined cataract and glaucoma surgery significantly decreased IOP. For deep sclerectomy vs deep sclerectomy plus phacoemulsification and canaloplasty vs phaco-canaloplasty, the differences in IOPR% were not all statistically significant while trabeculotomy was detected to gain a quantitatively greater IOPR% compared with trabeculotomy plus phacoemulsification. Furthermore, there was no statistical significance in the complete and qualified success rate, and the rates of adverse incidents for trabeculotomy vs trabeculotomy plus phacoemulsification.CONCLUSION： Compared with trabeculotomy plus phacoemulsification, trabeculectomy alone is more effective in lowering IOP and the number of glaucoma medications, while the two surgeries can not demonstrate statistical differences in the complete success rate, qualified success rate, or incidence of adverse incidents.

Effect of screening colonoscopy frequency on colorectal cancer mortality in patients with a family history of colorectal cancer

BACKGROUND Colorectal cancer is a common malignant tumor in China,and its incidence in the elderly is increasing annually.Inflammatory bowel disease is a group of chronic non-specific intestinal inflammatory diseases,including ulcerative colitis and Crohn’s disease.We included the clinicopathological and follow-up data of patients with colorectal cancer who underwent laparoscopic colectomy or open colectomy at our Gastrointestinal Department between January 2019 and December 2022.Surgical indicators,oncological indicators,and survival rates were compared between the groups.The results of 104 patients who met the above criteria were extracted from the database(laparoscopic colectomy group=63,open colectomy group=41),and there were no statistically significant differences in the baseline data or follow-up time between the two groups.RESULTS Intraoperative blood loss,time to first ambulation,and time to first fluid intake were significantly lower in the laparoscopic colectomy group than in the open colectomy group.The differences in overall mortality,tumor-related mortality,and recurrence rates between the two groups were not statistically significant,and survival analysis showed that the differences in the cumulative overall survival,tumor-related survival,and cumulative recurrence-free rates between the two groups were not statistically significant.CONCLUSION In elderly patients with colorectal cancer,laparoscopic colectomy has better short-term outcomes than open colectomy,and laparoscopic colectomy has superior long-term survival outcomes compared with open colectomy.

Surgical Treatment of the Upper Urinary Tract Lithiasis at the Urology Department of the Hopital General Idrissa Pouye

Upper urinary tract lithiasis is a condition characterized by the presence of stones which is a stony concretion of crystallized substances in the kidney and/or ureter. Objective: The objective of this work is to study the epidemiological, clinical and therapeutic aspects of upper urinary tract stones on the one hand, then to compare the different types of surgical treatments and their results. Materials and Methods: This is a retrospective and descriptive study focusing on the surgical management of upper urinary tract stones, between January 2017 and December 2020, at the Urology department of the Hopital General Idrissa Pouye. Results: During the study period, 7.59% of surgical interventions performed were related to the treatment of upper urinary tract stones. Average age was 45.20 ± 16.4 years, the age group [41 - 60] years was more affected with 42.68%. A history of urolithiasis was present in 25.52% of cases. Lower back pain was present in 97.48% of cases. On URO-CT scan, the stone was located more at the level of the ureter (49.57%). The size between 10 to 15 mm was more frequent (30.96%) and the density greater than 1000 HU was more frequent (33.47%). The most used therapeutic procedure was ureteroscopy (52.08%), followed by PCNL (40.83%) and open surgery (7.08%). The success rate (stone free) was 93.68% for the URS, 89.36% for the PCNL. The length of hospital stay for open surgery was 6.76 ± 4.25, for PCNL 2.62 ± 2 days and for URS 1.75 ± 1.62 days. Postoperative complications were present in 23.52% for open surgery, 11.22% for PCNL and 8% for URS. Conclusion: Urolithiasis is constantly growing in our regions. Effective endourological treatment is increasingly replacing open surgery. However, global access to these new techniques in our regions is slow to be effective.

Clinical Application Analysis of Laparoscopic-Assisted Total Gastrectomy in the Surgical Treatment of Gastric Cancer

Objective:To investigate the clinical application effect of laparoscopic-assisted total gastrectomy in the surgical treatment of gastric cancer.Methods:The clinical data of 86 COPD patients included in the study were collected and divided into 43 cases each in Groups A and B using the randomization method,with open total gastrectomy in Group A and laparoscopic-assisted total gastrectomy in Group B.The clinical indexes,pain levels,and complications of patients in the two groups were observed in combination with the indexes.Results:The baseline data of the two groups of patients were not statistically significant(all P>0.05);the operation time,incision length,first flatulence time,and hospitalization time of patients in Group B were shorter than those in Group A(all P=0.000);the NRS scores of patients in Group B on the 1st postoperative day and the 2nd postoperative day were significantly lower than those in Group A(t=23.443,t=28.784,all P=0.000);the total complication rate of patients in Group B(1;2.33%)was significantly lower than that of Group A(9;20.94%)(χ^(2)=7.242,P=0.007).Conclusion:In the surgical treatment of gastric cancer,laparoscopic-assisted total gastrectomy can promote patients’recovery,reduce patients’pain,and lower the probability of complications.

Comparison of short-and long-term outcomes of laparoscopic vs open resection for gastric gastrointestinal stromal tumors

AIM To compare the short-and long-term outcomes of laparoscopic(LR) vs open resection(OR) for gastric gastrointestinal stromal tumors(g GISTs).METHODS In total, 301 consecutive patients undergoing LR or OR for pathologically confirmed g GISTs from 2005 to 2014 were enrolled in this retrospective study. After exclusion of 77 patients, 224 eligible patients were enrolled(122 undergoing LR and 102 undergoing OR). The demographic, clinicopathologic, and survival data of all patients were collected. The intraoperative, postoperative, and long-term oncologic outcomes were compared between the LR and OR groups following the propensity score matching to balance the measured covariates between the two groups.RESULTS After 1:1 propensity score matching for the set of covariates including age, sex, body mass index, American Society of Anesthesiology score, tumor location, tumor size, surgical procedures, mitotic count, and risk stratification, 80 patients in each group were included in the final analysis. The baseline parameters of the two groups were comparable after matching. TheLR group was significantly superior to the OR group with respect to the operative time, intraoperative blood loss, postoperative first flatus, time to oral intake, and postoperative hospital stay(P < 0.05). No differences in perioperative blood transfusion or the incidence of postoperative complications were observed between the two groups(P > 0.05). No significant difference was found in postoperative adjuvant therapy(P = 0.587). The mean follow-up time was 35.30 ± 26.02(range, 4-102) mo in the LR group and 40.99 ± 25.07(range, 4-122) mo in the OR group with no significant difference(P = 0.161). Survival analysis showed no significant difference in the disease-free survival time or overall survival time between the two groups(P > 0.05).CONCLUSION Laparoscopic surgery for g GISTs is superior to open surgery with respect to intraoperative parameters and postoperative outcomes without compromising longterm oncological outcomes.

Comparison of clinical efficacy and postoperative inflammatory response between laparoscopic and open radical resection of colorectal cancer

BACKGROUND In recent years,the incidence of colorectal cancer(CRC)has increased annually,which has seriously threatened the health and quality of life of patients.In the treatment of CRC,both laparoscopic and radical resection are widely used.AIM To explore and discuss clinical efficacy and postoperative inflammatory response of laparoscopic and open radical resection of CRC.METHODS A total of 96 patients with CRC diagnosed in our hospital from March 2016 to April 2021 were selected,and were divided into the study group(n=48)and control group(n=48)using a simple random method.The control group was treated with open radical resection of CRC,and the study group was treated with laparoscopic radical resection of CRC.The perioperative conditions(operation time,intraoperative blood loss,the recovery time of gastrointestinal function,number of lymph node dissections and length of hospital stay),inflammatory response index levels[interleukin(IL)-6,IL-8,IL-10,C-reactive protein(CRP)]before and after operation,pain stress response indices[levels of neuropeptide(NPY),prostaglandin E2(PGE2),5-hydroxytryptamine(5-HT)],and the incidence of the complications between the two groups were counted.RESULTS The operation time in the study group was(186.18±33.54 min),which was longer than that of the control group(129.38±26.83 min),but the intraoperative blood loss(111.34±21.45 mL),recovery time of gastrointestinal function(25.35±4.55 h),and hospital stay(10.09±2.38 d)were better than those in the control group(163.77±32.41 mL,36.06±7.13 h,13.51±3.66 d)(P<0.05).There was no significant difference in the number of lymph node dissections between the study group(15.19±3.04)and the control group(16.20±2.98)(P>0.05).There was no significant difference between the levels of serum IL-6(9.79±4.11 ng/mL),IL-8(3.79±1.71 ng/L),IL-10(48.96±12.51 ng/L)and CRP(7.98±2.33 mg/L)in the study group and the control group(10.56±3.78 ng/mL,4.08±1.45 ng/L,50.13±11.67 ng/L,8.29±2.60 mg/L)before the operation(P>0.05).After the operation,there was no significant difference between the levels of serum IL-6(19.11±6.68 ng/mL).There was no significant difference in serum NPY(109.79±13.46 UG/L),PGE2(269.54±37.34 ng/L),5-HT(151.70±18.86 ng/L)between the study group and the control group(113.29±15.01 UG/L,273.91±40.04 ng/L,148.85±20.45 ng/L)before the operation(P>0.05).The incidence of the complications in the study group(4.17%)was lower than that of the control group(18.75%)(P<0.05).CONCLUSION Laparoscopic radical resection of CRC can reduce surgical trauma,inflammatory response and pain stress caused by surgery,which shortens rehabilitation of patients,with a low incidence of complications.

Contemporary techniques and outcomes of surgery for locally advanced renal cell carcinoma with focus on inferior vena cava thrombectomy:The value of a multidisciplinary team

Objective:To report the outcomes of surgery for a contemporary series of patients with locally advanced non-metastatic renal cell carcinoma(RCC)treated at a referral academic centre,focusing on technical nuances and on the value of a multidisciplinary team.Methods:We queried our prospective institutional database to identify patients undergoing surgical treatment for locally advanced(cT3-T4 N0-1 M0)renal masses suspected of RCC at our centre between January 2017 and December 2020.Results:Overall,32 patients were included in the analytic cohort.Of these,12(37.5%)tumours were staged as cT3a,8(25.0%)as cT3b,5(15.6%)as cT3c,and 7(21.9%)as cT4;6(18.8%)patients had preoperative evidence of lymph node involvement.Nine(28.1%)patients underwent nephron-sparing surgery while 23(71.9%)received radical nephrectomy.A template-based lymphadenectomy was performed in 12 cases,with evidence of disease in 3(25.0%)at definitive histopathological analysis.Four cases of RCC with level IV inferior vena cava thrombosis were successfully treated using liver transplant techniques without the need for extracorporeal circulation.While intraoperative complications were recorded in 3(9.4%)patients,no postoperative major complications(Clavien-Dindo3)were observed.At histopathological analysis,2(6.2%)patients who underwent partial nephrectomy harboured oncocytoma,while the most common malignant histotype was clear cell RCC(62.5%),with a median Leibovich score of 6(interquartile range 5e7).Conclusion:Locally advanced RCC is a complex and heterogenous disease posing several challenges to surgical teams.Our experience confirms that provided careful patient selection,surgery in experienced hands can achieve favourable perioperative,oncological,and functional outcomes.

Giant bile duct dilatation in newborn:A case report

BACKGROUND Giant congenital biliary dilation(CBD)is a rare condition observed in clinical practice.Infants born with this condition often experience a poor overall health status,and the disease progresses rapidly,leading to severe biliary obstruction,infections,pressure exerted by the enlarged CBD on abdominal organs,disturbances in the internal environment,and multiple organ dysfunction.The treatment of giant CBD using laparoscopy is challenging due to the high degree of variation in the shape of the bile duct and other organs,making it difficult to separate the bile duct wall from adjacent tissues or to control bleeding.CASE SUMMARY Herein,we present the details of an 11-d-old male newborn who was diagnosed with giant CBD.The patient was admitted to the neonatal surgery department of our hospital due to a history of common bile duct cyst that was detected more than 3 mo ago,and also because the patient had been experiencing yellowish skin for the past 9 d.The abnormal echo in the fetal abdomen was first noticed by the patient’s mother during a routine ultrasound examination at a local hospital,when the patient was at 24 wk+6 d of pregnancy.This finding raised concerns about the possibility of congenital biliary dilatation(22 mm×21 mm).Subsequent ultrasound examinations at different hospitals consistently confirmed the presence of a congenital biliary dilatation.No specific treatment was administered for biliary dilatation during this period.A computed tomography scan conducted during the hospitalization revealed a large cystic mass in the right upper quadrant and pelvis,measuring approximately 9.2 cm×7.4 cm×11.3 cm.Based on the CONCLUSION The analysis reveals that prenatal imaging techniques,such as ultrasound and magnetic resonance imaging,play a crucial role in the early diagnosis,fetal prognosis,and treatment plan for giant CBD.Laparoscopic surgery for giant CBD presents certain challenges,including difficulties in separating the cyst wall,anastomosis,and hemostasis,as well as severe biliary system infection and ulceration.Consequently,there is a high likelihood of converting to laparotomy.The choice between surgical methods like hepaticojejunostomy(HJ)or hepaticoduodenostomy has not been standardized yet.However,we have achieved favorable outcomes using HJ.Preoperative management of inflammation,biliary drainage,liver function protection,and supportive treatment are particularly vital in improving children’s prognosis.After discharge,it is essential to conduct timely reexamination and close follow-up to identify potential complications.

Transition from open to robotic assisted liver resection:A retrospective comparative study.Is experience of laparoscopic liver resections needed?

Objective:The authors present outcomes of robotic liver resections in comparison with open technique questioning the need to have experience of laparoscopy for such procedures before transition to robotic assisted.Materials and methods:Retrospective review of liver resections done robotically from February 2015 to June 2017 compared to matched control cohort of open cases from January 2012 to December 2016.Results:Twenty-one patients in the study groupwere comparedwithmatched control of 42 open cases(1:2 ratio).The types of procedure were similar in both the groups.There were 4 left lateral hepatectomy,3 left hepatectomy,and 1 left hepatectomy with hepatico-jejunostomy,3 right hepatectomy,3 right posterior sectorectomy,4 bisegmentectomy and 4 mono-segmentectomy.There were 9 patients with primary liver cancer,2 each with livermetastasis and carcinoma gall bladder and 8 patients had benign liver disease.Mean blood losswas 370±311ml in the robotic group compared to 451±330ml in control group(p=0.06).Minor complications developed in 19.0%of robotic cases compared to 40.5%in open surgery,while major complications occurred in 4.7%of robotic cases compared to 7.1%of open cases.Mean hospital staywas 5.3±0.8 days for the robotic group and 7.7±4.2 days for open group(p=0.02).Local tumor recurrence occurred in 1 out of 13 resections done for malignancy in the robotic group and 7 out of 26 in the open group.Conclusion:This study highlights the utility of surgical robots for segmental and complex liver resections with equivalent outcomes and decreased length of hospital stay compared to open surgery without having experience of same with the laparoscopy.
