Right hemicolectomy combined with duodenum-jejunum Roux-en-Y anastomosis for hepatic colon carcinoma invading the duodenum:A single-center case series

BACKGROUND Hepatic colon carcinoma invading the duodenum is not common in clinical practice.Surgical treatment of colonic hepatic cancer that invades the duodenum is difficult,and the surgical risk is high.AIM To discuss the efficacy and safety of duodenum-jejunum Roux-en-Y anastomosis for the treatment of hepatic colon carcinoma invading the duodenum.METHODS From 2016 to 2020,11 patients from Panzhihua Central Hospital diagnosed with hepatic colon carcinoma were enrolled in this study.Clinical and therapeutic effects and prognostic indicators were retrospectively analyzed to determine the efficacy and safety of our surgical procedures.All patients underwent radical resection of right colon cancer combined with duodenum-jejunum Roux-en-Y anastomosis.RESULTS The median tumor size was 65 mm(r50-90).Major complications(ClavienDindoI-II)occurred in 3 patients(27.3%);the average length of hospital stay was 18.09±4.21 d;and only 1 patient(9.1%)was readmitted during the 1st mo after the surgery.The 30-d mortality rate was 0%.After a median follow-up of 41 m(r7-58),the disease-free survival at 1,2,and 3 years was 90.9%,90.9%and 75.8%,respectively;the overall survival at 1,2,and 3 years was 90.9%.CONCLUSION In selected patients,radical resection of right colon cancer combined with duodenum-jejunum Roux-en-Y anastomosis is clinically effective,and the complications are manageable.The surgical procedure also has an acceptable morbidity rate and mid-term survival.

Comparison between laparoscopic uncut Roux-en-Y and Billroth Ⅱ with Braun anastomosis after distal gastrectomy:A meta-analysis

BACKGROUND Conventional Billroth Ⅱ(BⅡ) anastomosis after laparoscopic distal gastrectomy(LDG) for gastric cancer(GC) is associated with bile reflux gastritis, and Roux-enY anastomosis is associated with Roux-Y stasis syndrome(RSS). The uncut Rouxen-Y(URY) gastrojejunostomy reduces these complications by blocking the entry of bile and pancreatic juice into the residual stomach and preserving the impulse originating from the duodenum, while BⅡ with Braun(BB) anastomosis reduces the postoperative biliary reflux without RSS. Therefore, the purpose of this study was to compare the efficacy and safety of laparoscopic URY with BB anastomosis in patients with GC who underwent radical distal gastrectomy.AIM To evaluate the value of URY in patients with GC.METHODS PubMed, Embase, Web of Science, Cochrane Library, Chinese National Knowledge Infrastructure, Wanfang, Chinese Biomedical Database, and VIP Database for Chinese Technical Periodicals(VIP) were used to search relevant studies published from January 1994 to August 18, 2021. The following databases were also used in our search: Clinicaltrials.gov, Data Archiving and Networked Services, the World Health Organization International Clinical Trials Registry Platform Search Portal(https://www.who.int/clinical-trials-registry-platform/the-ictrp-search-portal), the reference lists of articles and relevant conference proceedings in August 2021. In addition, we conducted a relevant search by Reference Citation Analysis(RCA)(https://www.referencecitationanalysis.com). We cited highquality references using its results analysis functionality. The methodological quality of the eligible randomized clinical trials(RCTs) was evaluated using the Cochrane Risk of Bias Tool, and the non-RCTs were evaluated using the Newcastle-Ottawa scale. Statistical analyses were performed using Review Manager(Version 5.4).RESULTS Eight studies involving 704 patients were included in this meta-analysis. The incidence of reflux gastritis [odds ratio = 0.07, 95% confidence interval(CI): 0.03-0.19, P < 0.00001] was significantly lower in the URY group than in the BB group. The pH of the postoperative gastric fluid was lower in the URY group than in the BB group at 1 d [mean difference(MD) =-2.03, 95%CI:(-2.73)-(-1.32),P < 0.00001] and 3 d [MD =-2.03, 95%CI:(-2.57)-(-2.03), P < 0.00001] after the operation. However,no significant difference in all the intraoperative outcomes was found between the two groups.CONCLUSION This work suggests that URY is superior to BB in gastrointestinal reconstruction after LDG when considering postoperative outcomes.

Passive-bending,short-type single-balloon enteroscope for endoscopic retrograde cholangiopancreatography in Roux-en-Y anastomosis patients

AIM:To evaluate short-type-single-balloon enteroscope(SBE) with passive-bending,high-force transmission functions for endoscopic retrograde cholangiopancreatography(ERCP) in patients with Roux-en-Y anastomosis.METHODS:Short-type SBE with this technology(SIF-Y0004-V01; working length,1520 mm; channel diameter,3.2 mm) was used to perform 50 ERCP procedures in 37 patients with Roux-en-Y anastomosis.The rate of reaching the blind end,time required to reach the blind end,diagnostic and therapeutic success rates,and procedure time and complications were studied retrospectively and compared with the results of 34 sessions of ERCP performed using a short-type SBE without this technology(SIF-Y0004; working length,1520 mm; channel diameter,3.2 mm) in 25 patients.RESULTS:The rate of reaching the blind end was 90% with SIF-Y0004-V01 and 91% with SIF-Y0004(P = 0.59).The median time required to reach the papilla was significantly shorter with SIF-Y0004-V01 than with SIF-Y0004(16 min vs 24 min,P = 0.04).The diagnostic success rate was 93% with SIFY0004-V01 and 84% with SIF-Y0004(P = 0.17).The therapeutic success rate was 95% with SIF-Y0004-V01 and 96% with SIF-Y0004(P = 0.68).The median procedure time was 40 min with SIF-Y0004-V01 and 36 min with SIF-Y0004(P = 0.50).The incidence of hyperamylasemia was 6.0% in the SIF-Y0004-V01 group and 14.7% in the SIF-Y0004 group(P = 0.723).The incidence of pancreatitis was 0% in the SIFY0004-V01 group and 5.9% in the SIF-Y0004 group(P > 0.999).The incidence of gastrointestinal perforation was 2.0%(1/50) in the SIF-Y0004-V01 group and 2.9%(1/34) in the SIF-Y0004 group(P > 0.999).CONCLUSION:SIF-Y0004-V01 is useful for ERCP inpatients with Roux-en-Y anastomosis and may reduce the time required to reach the blind end.

Application of single balloon enteroscopy-assisted therapeutic endoscopic retrograde cholangiopancreatography in patients after bilioenteric Roux-en-Y anastomosis: Experience of multi-disciplinary collaboration

BACKGROUND Bilioenteric Roux-en-Y anastomosis is one of the most complicated approaches for reconstructing the gastrointestinal tract, and endoscopic retrograde cholangiopancreatography (ERCP) is technically challenging in patients after bilioenteric Roux-en-Y anastomosis. The optimal endoscopic strategies for such cases remain unknown. AIM To explore the feasibility and effectiveness of single balloon enteroscopy-assisted (SBE-assisted) therapeutic ERCP in patients after bilioenteric Roux-en-Y anastomosis based on multi-disciplinary collaboration between endoscopists and surgeons as well as report the experience from China. METHODS This is a single center retrospective study. All of the SBE-assisted therapeutic ERCP procedures were performed by the collaboration between endoscopists and surgeons. The operation time, success rate, and complication rate were calculated. RESULTS Forty-six patients received a total of 64 SBE-assisted therapeutic ERCP procedures, with successful scope intubation in 60 (93.8%) cases and successful diagnosis in 59 (92.2%). All successfully diagnosed cases received successful therapy. None of the cases had perforation or bleeding during or after operation, and no post-ERCP pancreatitis occurred. CONCLUSION Based on multi-disciplinary collaboration, SBE-assisted therapeutic ERCP in patients after bilioenteric Roux-en-Y anastomosis is relatively safe and effective and has a high success rate.

Influence of different magnetic forces on the effect of colonic anastomosis in rats

BACKGROUND Despite much work having been conducted on magnetic compression anastomo-sis(MCA)in the digestive tract,there are no reports on the influence of magnetic force on the anastomosis.AIM To investigate the effect of different magnetic force magnets on the MCA of the digestive tract.METHODS Two groups of magnets of the same sizes but different magnetic forces were designed and produced.A total of 24 Sprague-Dawley rats were randomly assigned into two groups(powerful magnet group and common magnet group),with 12 rats in each group.Two types of magnets were used to complete the colonic side-to-side anastomosis of the rats.The operation time and magnet discharge time were recorded.The anastomotic specimens were obtained 4 wk after the operation and then the burst pressure and diameter of the anastomosis were measured,and the anastomosis was observed via the naked eye and subjected to histological examination.RESULTS The magnetic forces of the powerful and common magnet groups at zero distance were 8.26 N and 4.10 N,respectively.The colonic side-to-side anastomosis was completed in all 24 rats,and the operation success rate and postoperative survival rate were 100%.No significant difference was noted in the operation time between the two groups.The magnet discharge time of the powerful magnet group was slightly longer than that of the common magnet group,but the difference was not statistically significant(P=0.513).Furthermore,there was no statistical difference in the burst pressure(P=0.266)or diameter of magnetic anastomosis(P=0.095)between the two groups.The gross specimens of the two groups showed good anastomotic healing,and histological observation indicated good mucosal continuity without differences on healing.CONCLUSION In the rat colonic side-to-side MCA model,both the powerful magnet with 8.26 N and the common magnet with 4.10 N showed no significant impact on the anastomosis establishment process or its effect.

Comparison between double-balloon and single-balloon enteroscopy in therapeutic ERC after Roux-en-Y entero-enteric anastomosis

AIM:To compare the efficacy of double-balloon enteroscopy (DBE) and single-balloon enteroscopy (SBE) in therapeutic endoscopic retrograde cholangiography (ERC) in patients with Roux-en-Y entero-enteric anastomosis.METHODS:Retrospective analysis of our patient cohort revealed 4 patients with enterobiliary anastomosis and Roux-en-Y entero-enteric anastomosis who underwent repeated ERC with DBE and SBE because of recurrent cholangitis.RESULTS:A total of 38 endoscopic retrograde cholangiopancreatography procedures were performed in 25 patients with Roux-en-Y entero-enteric anastomosis.DBE was used in 29 procedures and SBE in 9.The 4 patients who underwent repeated ERC with DBE and SBE suffered from recurrent cholangitis due to stenosis of the enterobiliary anastomosis.ERC was performed repeatedly to achieve balloon dilation with/without biliary stone extraction and multiple stent placement at the level of the enterobiliary anastomosis.In all 4 patients DBE and SBE were equally successful.Compared to DBE,SBE was equally effective in passing the Roux-en-Y entero-enteric anastomosis,reaching the enterobiliary anastomosis and performing therapeutic ERC.CONCLUSION:This retrospective comparison shows that DBE and SBE are equally successful in the performance of therapeutic ERC at the level of the enterobiliary anastomosis after Roux-en-Y entero-enteric anastomosis.

Evaluation of bacterial contamination and medium-term oncological outcomes of intracorporeal anastomosis for colon cancer:A propensity score matching analysis

BACKGROUND Although intracorporeal anastomosis(IA)for colon cancer requires longer operative time than extracorporeal anastomosis(EA),its short-term postoperative results,such as early recovery of bowel movement,have been reported to be equal or better.As IA requires opening the intestinal tract in the abdominal cavity under pneumoperitoneum,there are concerns about intraperitoneal bacterial infection and recurrence of peritoneal dissemination due to the spread of bacteria and tumor cells.However,intraperitoneal bacterial contamination and medium-term oncological outcomes have not been clarified.abdominal cavity in IA.METHODS Of 127 patients who underwent laparoscopic colon resection for colon cancer from April 2015 to December 2020,75 underwent EA(EA group),and 52 underwent IA(IA group).After propensity score matching,the primary endpoint was 3-year disease-free survival rates,and secondary endpoints were 3-year overall survival rates,type of recurrence,surgical site infection(SSI)incidence,number of days on antibiotics,and postoperative biological responses.RESULTS Three-year disease-free survival rates did not significantly differ between the IA and EA groups(87.2%and 82.7%,respectively,P=0.4473).The 3-year overall survival rates also did not significantly differ between the IA and EA groups(94.7%and 94.7%,respectively;P=0.9891).There was no difference in the type of recurrence between the two groups.In addition,there were no significant differences in SSI incidence or the number of days on antibiotics;however,postoperative biological responses,such as the white blood cell count(10200 vs 8650/mm^(3),P=0.0068),C-reactive protein(6.8 vs 4.5 mg/dL,P=0.0011),and body temperature(37.7 vs 37.5℃,P=0.0079),were significantly higher in the IA group.CONCLUSION IA is an anastomotic technique that should be widely performed because its risk of intraperitoneal bacterial contamination and medium-term oncological outcomes are comparable to those of EA.

Benign stricture of bilioenteric anastomosis after Whipple withsynthetic polypropylene suture

To the Editor:Biliary stricture formation at the bilioenteric anastomosis is an infrequent complication(2%-3%)after pancreaticoduodenectomy;the average presentation is within 13-14 months(range from 1 month to 9 years)after surgery[1,2].While the etiology is unknown,development of biliary stricture has shown to be more likely if a bile leak occurs in the postoperative period[3,4]and with younger patients[5].

T-tube bridging fistula jejunal anastomosis for treatment of pancreatic lumbar dorsal fistula after necrotizing pancreatitis

Infectious pancreatic necrosis causes external pancreatic fistula in some patients.Generally,external pancreatic fistula requires fistula-gastric and/or intestinal anastomosis,and digestive endoscopic interventional treatment[1–3].It is especially difficult to treat external pancreatic fistulas with small fistulas where the external fistula is located in the lower back.The common treatment is to remove the body and tail of the pancreas and the spleen.This operation is very traumatic.A new pancreatic fistula may still occur at the pancreatic stump.The above operations may lead to unnecessary resection of the spleen,colon injury and other complications.In order to solve this problem,we innovatively used T-tube bridging fistula jejunal anastomosis plus continuous negative pressure suction to treat three cases of external pancreatic fistulas in the lower back,and all of them achieved good results.

New anti-mesenteric delta-shaped stapled anastomosis: Technical report with short-term postoperative outcomes in patients with Crohn’s disease

BACKGROUND Medical treatment for Crohn’s disease(CD)has continuously improved,which has led to a decrease in surgical recurrence rates.Despite these advancements,25%of patients will undergo repeat intestinal surgery.Recurrence of CD com-monly occurs on the mesentery side of the anastomosis site.AIM To compare the new anti-mesenteric side-to-side delta-shaped stapled anasto-mosis(DSA)with the conventional stapled functional end-to-end anastomosis(CSA).METHODS This retrospective study included CD patients who underwent ileo-ileal or ileo-colic anastomosis between January 2020 and December 2023.The DSA technique employed a stapler to maintain the concept of anti-mesentery side-to-side ana-stomosis by performing a 90°vertical closure of the open window compared with the CSA technique.At the corner where the open window is closed,the DSA avoids forming a pouch and creates an anastomosis resembling a delta shape within the intestinal lumen.We compared demographics,preoperative condition,operative findings,and operative outcomes for the two techniques.RESULTS The study included 175 patients,including 92 in the DSA group and 83 in the CSA group.The two groups were similar in baseline characteristics,preoperative medical treatment,and operative findings except for the Montreal classification location.The 30-days postoperative complication rate was signi-ficantly lower in the DSA group compared with the CSA group(16.3%vs 32.5%,P=0.009).Ileus incidence was significantly lower in the DSA group than in the CSA group(4.3%vs 14.5%,P=0.033),and the hospital stay was shorter in the DSA group than in the CSA group(5.67±1.53 days vs 7.39±3.68 days,P=0.001).CONCLUSION The DSA technique was feasible and showed comparable postoperative outcomes with lower short-term complic-ations compared with the CSA technique.Further studies on CD recurrence and long-term complications are warranted.

Clinical efficacy of modified Kamikawa anastomosis in patients with laparoscopic proximal gastrectomy

BACKGROUND With the increasing incidence of proximal gastric cancer,laparoscopic proximal gastrectomy has been applied.However,reflux esophagitis often occurs after traditional esophagogastric anastomosis.In order to solve this problem,several methods of digestive tract reconstruction have emerged,but the most satisfying method remains to be discussed.Therefore,we modified traditional Kamikawa anastomosis to investigate the appropriate digestive tract reconstruction in laparo-scopic proximal gastrectomy.All the patients were successfully operated on without conversion to laparotomy.The duration of operation and digestive tract reconstruction were 203.500(150-224)min and 87.500(73-111)min,respectively.The intraoperative amount of bleeding was 20.500 mL±0.696 mL.The time of postoperative first flatus,the first postoperative fluid intake,and the postoperative length of stay were 2(1-3)d,4(3-5)d,and 9(8-10)d,respectively.All the patients were followed up for 12-23 months.The body mass index at 6 and 12 months after surgery were 22.577 kg/m2±3.098 kg/m2 and 22.594 kg/m2±3.207 kg/m2,respectively.The nutrition risk screening 2002 score,the patient-generated subjective global assessment score,and the gastroesophageal reflux disease scale score were good at 6 and 12 months after surgery.Reflux esophagitis and anastomotic stenosis were not observed in any of the patients during their 12-month postoperative gastroscopy or upper gastrointestinal tract visits.All the patients exhibited no tumor recurrence or metastasis.CONCLUSION The modified Kamikawa anastomosis is safe and feasible for laparoscopic proximal gastrectomy and has good antireflux effects and nutritional status.

Primary repair of esophageal atresia Gross type C via thoracoscopic magnetic compression anastomosis:Is it the best option?

Magnetic compression anastomosis is a promising treatment option for patients with complex esophageal atresia;but,at the present time,should not be the first therapeutic option in those cases where the surgeon can perform a primary anastomosis of the two ends of the esophagus with acceptable tension.

Effect of growth hormone on colonic anastomosis after intraperitoneal administration of 5-fluorouracil, bleomycin and cisplatin: An experimental study

BACKGROUND Growth hormone(GH)plays a crucial role in wound healing and tissue repair in postoperative patients.In particular,colonic anastomosis healing following colorectal surgery is impaired by numerous chemotherapy agents.AIM To investigate whether GH can improve the healing of a colonic anastomosis following the adverse effects of intraperitoneal administration of 5-fluorouracil(5-FU),bleomycin and cisplatin.METHODS Eighty Wistar rats underwent laparotomy and a 1 cm-resection of the transverse colon,followed by an end-to-end anastomosis under general anesthesia.The rats were blindly allocated into four equal groups and administered a different daily intraperitoneal therapeutic regimen for 6 days.The control group(A)received normal saline.Group B received chemotherapy with 5-FU(20 mg/kg),bleomycin(4 mg/kg)and cisplatin(0.7 mg/kg).Group C received GH(2 mg/kg),and group D received the aforementioned combination chemotherapy and GH,as described.The rats were sacrificed on the 7th postoperative day and the anastomoses were macroscopically and microscop-ically examined.Body weight,bursting pressure,hydroxyproline levels and inflammation markers were measured.RESULTS All rats survived until the day of sacrifice,with no infections or other complications.A decrease in the body weight of group D rats was observed,not statistically significant compared to group A(P=1),but significantly different to groups C(P=0.001)and B(P<0.01).Anastomotic dehiscence rate was not statistically different between the groups.Bursting pressure was not significantly different between groups A and D(P=1.0),whereas group B had a significantly lower bursting pressure compared to group D(P<0.001).All groups had significantly more adhesions than group A.Hydroxyproline,as a measurement of collagen deposition,was significantly higher in group D compared to group B(P<0.05),and higher,but not statistically significant,compared to group A.Significant changes in group D were recorded,compared to group A regarding inflammation(3.450 vs 2.900,P=0.016)and fibroblast activity(2.75 vs 3.25,P=0.021).Neoangiogenesis and collagen deposition were not signifi-cantly different between groups A and D.Collagen deposition was significantly increased in group D compared to group B(P<0.001).CONCLUSION Intraperitoneal administration of chemotherapy has an adverse effect on the healing process of colonic anastomosis.However,GH can inhibit the deleterious effect of administered chemotherapy agents and induce colonic healing in rats.

Impact of different anastomosis methods on post-recurrence after intestinal resection for Crohn's disease:A meta-analysis

BACKGROUND Crohn's disease(CD)is a chronic inflammatory disease of the gastrointestinal tract,often requiring intestinal resection as a common treatment.However,recurrence after surgery is common.The anastomotic configuration after bowel resection appears to be associated with the recurrence of CD.Previous studies have suggested that the Kono-S anastomosis may help to reduce the recurrence rate.However,the results remain controversial.Therefore,evidence-based evidence is needed to prove the advantages of Kono-S anastomosis.AIM To measure the influence of anastomosis techniques on the long-term relapse rate of CD by conducting a meta-analysis.METHODS PubMed,Scopus,and Cochrane Library were searched until October 8,2023.Patients who underwent intestinal resection due to CD were included.The intervention measures included Kono-S anastomosis,whereas the control group received traditional anastomosis such as end-to-end,end-to-side,and side-to-side anastomosis.Only randomized clinical trials and observational studies were included.The primary outcome measures were hospital stay post-surgery,overall postoperative complication incidence,the proportion of Clavien-Dindo grade IIIa or higher,overall postoperative recurrence rate,and Rutgeerts score.RESULTS From 2011 to 2023,six articles met the inclusion and exclusion criteria.The results indicated that Kono-S anastomosis can reduce the hospital stay post-surgery of patients with CD[MD=-0.26,95%CI:-0.42 to-0.10,P=0.002]than other traditional anastomosis methods.Compared to other traditional anastomosis methods,Kono-S anastomosis can significantly reduce the total recurrence rate[MD=0.40,95%CI:0.17 to 0.98,P=0.05]and postoperative Rutgeerts score[MD=-0.81,95%CI:-0.96 to-0.66,P<0.001]in patients with CD.However,there is no significant disparity in the overall occurrence of postoperative complications and the proportion of Clavien-Dindo≥IIIa.CONCLUSION Kono-S anastomosis has the potential to expedite the recuperation of CD and diminish relapse hazards;however,additional larger trials are necessary to authenticate its effectiveness.

Magnetic compression anastomosis to restore biliary tract continuity after obstruction following major abdominal trauma:A case report

BACKGROUND The combination of magnetic compression anastomosis(MCA)and endoscopy has been used to treat biliary stricture after liver transplantation.However,its use for the treatment of complex biliary obstruction after major abdominal trauma has not been reported.This case report describes the successful use of MCA for the treatment of biliary obstruction resulting from major abdominal trauma.A 23-year-old man underwent major abdominal surgery(repair of liver rupture,right half colon resection,and ileostomy)following a car accident one year ago.The abdominal drainage tube,positioned at the Winslow foramen,was draining approximately 600-800 mL of bile per day.During the two endoscopic retrograde cholangiopancreatography procedures,the guide wire was unable to enter the common bile duct,which prevented placement of a biliary stent.MCA combined with endoscopy was used to successfully achieve magnetic anastomosis of the peritoneal sinus tract and duodenum,and then a choledochoduodenal stent was placed.Finally,the external biliary drainage tube was removed.The patient achieved internal biliary drainage leading to the removal of the external biliary drainage tube,which improved the quality of life.CONCLUSION Magnetic compression technique can be used for the treatment of complex biliary obstruction with minimal operative trauma.

Evaluating bacterial contamination and surgical site infection risks in intracorporeal anastomosis: Role of bowel preparation

We recently read the study by Kayano et al on intracorporeal anastomosis(IA)for colon cancer,which assessed bacterial contamination and medium-term onco-logical outcomes and affirmed that IA is analogous to extracorporeal anastomosis in reducing intraperitoneal bacterial risk and achieving similar oncological results.Our commentary addresses gaps,particularly concerning bowel preparation and surgical site infections(SSIs),and highlights the need for comprehensive details on the bowel preparation methods that are currently employed,including mecha-nical bowel preparation,oral antibiotics(OA),their combination,and specific OA types.We emphasize the necessity for further analyses that investigate these me-thods and their correlation with SSI rates,to enhance clinical protocol guidance and optimize surgical outcomes.Such meticulous analyses are essential for refi-ning strategies to effectively mitigate SSI risk in colorectal surgeries.

Lymphovenous anastomosis and complex decongestive therapy for severe deformed lymphedema with recurrent infection:A case report

BACKGROUND Lower extremity lymphedema is a common complication following treatment for gynecological malignancies.Its incidence rate can reach up to 70%,affecting~20 million people worldwide.However,specialized treatment centers are scarce,and there is a lack of consensus on treatment approaches.Furthermore,there are even fewer reports on the systematic and effective treatment of severe lymphedema with malformations.Effective management of this condition remains a significant challenge for clinicians.CASE SUMMARY A 40-year-old woman developed bilateral leg swelling 6 years after receiving treatment for endometrial cancer.Since August 2018,she experienced>30 episodes of lymphangitis.Upon presentation,she exhibited bilateral leg swelling and deformation,with four large swellings in the posterior thigh that impeded movement,and pain in the limbs.Skin manifestations included lichenoid lesions and features of deep sclerosis.Radionuclide lymphoscintigraphy confirmed the diagnosis of lower limb lymphedema.After 6 mo of complex decongestive therapy(CDT)and three lymphaticovenous anastomosis(LVA)treatments,the patient lost 49 kg in weight.She also experienced a maximum circumference reduction of 35.2 cm in the left lower limb and 37.5 cm in the right lower limb.The leg pain disappeared,her swelling significantly decreased,and she regained the ability to walk,cycle,and run normally.CONCLUSION The combined application of CDT and LVA therapy demonstrates significant positive effects in the treatment of severe,deformed stage III lymphedema.

Radical Prostatectomy by Laparotomy: Retrospective Study Comparing Separate and Continuous Stitches in the Performance of Vesicourethral Anastomosis at a Single Center in the Public Health Network

Background: Prostate cancer ranks as the second most prevalent malignancy in men, with treatment strategies ranging from observation to various interventions. Radical prostatectomy is a common approach, aiming for a cure, and the technique for vesico-urethral anastomosis varies, employing separate or continuous stitches. However, a consensus on the optimal technique is lacking. This study aims to compare vesico-urethral anastomosis techniques (separate vs. continuous stitches) in laparotomy-based radical prostatectomies, evaluating peri and postoperative outcomes. Materials and Method: A retrospective analysis of 140 patients’ medical records yielded 86 eligible cases, divided into two groups based on anastomosis technique. Both groups underwent surgery at the same urology center between 2016 and 2019, with a follow-up period exceeding 12 months. Pre-operative characteristics were statistically similar between groups. Results: Perioperative complication rates did not significantly differ between the two techniques (p > 0.99). However, the continuous stitch group experienced a 20-minute longer procedure time (p 0.05), patients with continuous stitches had 2.5 times higher diaper usage at twelve months (p Conclusion: This research suggests that vesico-urethral anastomosis with separate stitches yields superior results in laparotomy-based radical prostatectomies compared to continuous stitches, demonstrating benefits in surgical time, hospital stay, sentinel drain duration, stenosis rates, and long-term urinary incontinence outcomes.

Experimental models of high-risk bowel anastomosis in rats:A systematic review

BACKGROUND Anastomotic leaks remain one of the most dreaded complications in gastrointestinal surgery causing significant morbidity,that negatively affect the patients’quality of life.Experimental studies play an important role in understanding the pathophysiological background of anastomotic healing and there are still many fields that require further investigation.Knowledge drawn from these studies can lead to interventions or techniques that can reduce the risk of anastomotic leak in patients with high-risk features.Despite the advances in experimental protocols and techniques,designing a high-quality study is still challenging for the investigators as there is a plethora of different models used.AIM To review current state of the art for experimental protocols in high-risk anastomosis in rats.METHODS This systematic review was performed according to The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.To identify eligible studies,a comprehensive literature search was performed in the electronic databases PubMed(MEDLINE)and Scopus,covering the period from conception until 18 October 2023.RESULTS From our search strategy 102 studies were included and were categorized based on the mechanism used to create a high-risk anastomosis.Methods of assessing anastomotic healing were extracted and were individually appraised.CONCLUSION Anastomotic healing studies have evolved over the last decades,but the findings are yet to be translated into human studies.There is a need for high-quality,well-designed studies that will help to the better understanding of the pathophysiology of anastomotic healing and the effects of various interventions.

Isoperistaltic vs antiperistaltic anastomosis after right hemicolectomy:A comprehensive review

To optimize the efficiency of ileocolic anastomosis following right hemicolectomy,several variations of the surgical technique have been tested.These include performing the anastomosis intra-or extracorporeally or performing a stapled or hand-sewn anastomosis.Among the least studied is the configuration of the two stumps(i.e.,isoperistaltic or antiperistaltic)in the case of a side-to-side anastomosis.The purpose of the present study is to compare the isoperistaltic and antiperistaltic side-to-side anastomotic configuration after right hemicolectomy by reviewing the relevant literature.High-quality literature is scarce,with only three studies directly comparing the two alternatives,and no study has revealed any significant differences in the incidence of anastomosis-related complications such as leakage,stenosis,or bleeding.However,there may be a trend towards an earlier recovery of intestinal function following antiperistaltic anastomosis.Finally,existing data do not identify a certain anastomotic configuration(i.e.,isoperistaltic or antiperistaltic)as superior over the other.Thus,the most appropriate approach is to master both anastomotic techniques and select between the two configurations based on each individual case scenario.
