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.

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.

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.

Novel method for esophagojejunal anastomosis after laparoscopic total gastrectomy:Semi-end-to-end anastomosis

AIM: To test a new safe and simple technique for circular-stapled esophagojejunostomy in laparoscopic total gastrectomy (LATG).

Proximal gastrectomy with jejunal interposition and TGRY anastomosis for proximal gastric cancer

AIM: To compare the short-term outcomes of patients who underwent proximal gastrectomy with jejunal interposition (PGJI) with those undergoing total gastrectomy with Roux-en-Y anastomosis (TGRY).

Surgical management in biliary restricture after Roux-en-Y hepaticojejunostomy for bile duct injury

AIM: To discuss the surgical method and skill of biliary restricture after Roux-en-Y hepaticojejunostomy for bile duct injury. METHODS: From November 2005 to December 2006, eight patients with biliary restricture after Roux-en-Y hepaticojejunostomy for bile duct injury were admitted to our hospital. Their clinical data were analyzed retrospectively. RESULTS: Bile duct injury was caused by cholecys- tectomy in the eight cases, including seven cases with laparoscopic cholecystectomy and one with mini- incision choleystectomy. According to the classification of Strasberg, type E1 injury was found in one patient, type E2 injury in three, type E3 injury in two and type E4 injury in two patients. Both of the type E4 injury patients also had a vascular lesion of the hepatic artery. Six patients received Roux-en-Y hepaticojejunostomy for the second time, and one of them who had type E4 injury with the right hepatic artery disruption received right hepatectomy afterward. One patient who had type E4 injury with the proper hepatic artery lesion underwent liver transplantation, and the remaining one with type E3 injury received external biliary drainage. All the patients recovered fairly well postoperatively. CONCLUSION: Roux-en-Y hepaticojejunostomy is still the main approach for such failed surgical cases with bile duct injury. Special attention should be paid to concomitant vascular injury in these cases. The optimal timing and meticulous and excellent skills are essential to the success in this surgery.

Magnetic compression anastomosis for reconstruction of digestive tract after total gastrectomy in beagle model

BACKGROUND Magnetic compression anastomosis(MCA)is a simple procedure contributing to a reliable anastomosis.However,digestive-tract reconstruction after total gastrectomy using MCA has not yet been reported.AIM To investigate the feasibility of MCA for simultaneous esophagojejunostomy and jejunojejunostomy after total gastrectomy using beagle dogs.METHODS Sixteen beagles were randomly divided into an MCA group(study group,n=8)and a manual-suture anastomosis group(control group,n=8).Two different magnetic anastomosis devices were used in the study group for esophagojejunal and jejunojejunal anastomoses.Both devices included a pair of circular daughter and parent magnets each.The time of esophagojejunostomy and jejunojejunostomy,postoperative complications,and survival rate of the two groups were compared.The dogs were sacrificed one month after the operation and their anastomotic specimens were obtained.Healing was observed by the naked eye and a light microscope.RESULTS Digestive-tract reconstruction after total gastrectomy was successfully completed in both groups(survival rate=100%).In the study group,esophagojejunal and jejunojejunal anastomoses took 6.13±0.58 and 4.06±0.42 min,respectively,significantly lower than those in the control group(15.63±1.53 min,P<0.001 and 10.31±1.07 min,P<0.001,respectively).Complications such as bleeding,anastomotic leakage,and anastomotic stenosis were not observed.In the study group,the magnets did not interfere with each other.Discharge time of the jejunojejunal magnetic anastomosis device was 10.75±1.28 d,while that of the esophagojejunal magnetic anastomosis device was 12.25±1.49 d.Residual silk was found in the control group.The study group showed a greater smoothness of the anastomosis than that of the control group.All layers of anastomosis healed well in both groups.CONCLUSION MCA is a safe and feasible procedure for digestive-tract reconstruction after total gastrectomy in this animal model.

Petersen's hernia with chylous ascites following laparoscopic total gastrectomy and Roux-en-Y anastomosis:A case report and review of literature

BACKGROUND Petersen’s hernia occurring through the epiploic foramen of the greater omentum,is an uncommon type of internal hernia.When it presents with complications such as chylous ascites,which is the lymphatic fluid accumulation in the abdominal cavity,it is particularly rare.Following laparoscopic total gastrectomy and Roux-en-Y anastomosis,the incidence of this condition is exceedingly low.CASE SUMMARY A 62-year-old male patient developed Petersen’s hernia following laparoscopic total gastrectomy(LTG)for gastric cancer,after Roux-en-Y anastomosis.Intestinal torsion and obstruction were experienced by the patient,along with a small amount of chylous ascites.Imaging studies and clinical assessment confirmed the diagnosis.Emergency surgery was performed promptly for the patient in the operating room.The twisted small intestine was reduced and the defect in Petersen’s space was repaired.The procedure was successful in the correction of the intestinal torsion and approximation of the hernia without the need for bowel resection.The patient’s condition significantly improved following the surgery.The ascites evolved from a milky white appearance to a pale yellow,with a substantial decrease in the triglyceride levels in the ascitic fluid,implying a favorable recovery trajectory.The patient was monitored closely and received appropriate care postoperatively,including nutritional support and fluid management.CONCLUSION This report illustrates the significance of recognizing Petersen’s hernia as a potential complication following gastrectomy for gastric cancer.It highlights the fundamental role of early surgical intervention in the effective management of such complications.The favorable outcome in this patient illustrates that prompt and appropriate surgical management can deter the necessity for more extensive procedures such as bowel resection.

Myoelectric activity and motility of the Roux limb after cut or uncut Roux-en-Y gastrojejunostomy

AIM: To explore the mechanisms of uncut Roux-en-Y gastrojejunostomy, which is used to decrease the occurrence of Roux stasis syndrome.METHODS: The changes of myoelectric activity, mechanic motility and interstitial cells of Cajal (ICC) of the Roux limb after cut or uncut Roux-en-Y gastrojejunostomy were observed. RESULTS: When compared with the cut group, the amplitude (1.15 ± 0.15 mV vs 0.48 ± 0.06 mV, P < 0.05) and frequency (14.4 ± 1.9 cpm vs 9.5 ± 1.1 cpm, P < 0.01) of slow waves and the incidence (98.2% ± 10.4% vs 56.6% ± 6.4%, P < 0.05) and amplitude (0.58 ± 0.08 mV vs 0.23 ± 0.06 mV, P < 0.01) of spike potential of the Roux limb in the uncut group were significantly higher. The migrating myoelectric complexes (MMC) phase Ⅲ duration in the uncut group was significantly prolonged (6.5 ± 1.1 min vs 4.4 ± 0.8 min, P < 0.05), while the MMC cycle obviously shortened (42.5 ± 6.8 vs 55.3 ± 8.2 min, P < 0.05). Both gastric emptying rate (65.5% ± 7.9% vs 49.3% ± 6.8%, P < 0.01) and intestinal impelling ratio (53.4% ± 7.4% vs 32.2% ± 5.4%, P < 0.01) in the uncut group were significantly increased. The contractile force index of the isolated jejunal segment in the uncut group was significantly higher (36.8 ± 5.1 vs 15.3 ± 2.2, P < 0.01), and the expression of c-kit mRNA was significantly increased in the uncut group (0.82 ± 0.11 vs 0.35 ± 0.06, P < 0.01). CONCLUSION: Uncut Roux-en-Y gastrojejunostomymay lessen the effects of operation on myoelectric activity such as slow waves, spike potential, and MMC, decrease the impairment of gastrointestinal motility, and remarkably increase the expression of c-kit mRNA.

Roux-en-Y choledochojejunostomy using novel magnetic compressive anastomats in canine model of obstructive jaundice

BACKGROUND:The traditional hand-sewn Roux-en-Y choledochojejunostomy is technically complicated,and the incidence of postoperative complications has remained high.A set of novel magnetic compressive anastomats was introduced to facilitate choledochojejunostomy and improve the prognosis of patients.METHODS:After ligating the common bile duct for 7 days,16 dogs were randomly divided into two groups (n=8 per group).Anastomats were used in the study group,and the traditional hand-sewn method was used in the control group for standard Roux-en-Y choledochojejunostomy.We compared the operation time,incidence of complications,gross appearance,and pathological disparity in stoma between the two groups in 1-month and 3-month follow-up examinations.RESULTS:The time spent on constructing the anastomosis for the study group was significantly shortened.Although no anastomotic stenosis occurred in the two groups,the narrowing rate of biliary-enteric anastomosis was much higher in the control group.There was one case of bile leakage in the control group,whereas no bile leakage occurred in the study group.A smoother surface,an improved layer apposition,and a lower local inflammatory response were identified in the anastomosis of the study group.CONCLUSION:The structures of the novel magnetic compressive anastomats are simple,and they are time-saving,safe and efficient for performing Roux-en-Y choledocho- jejunostomy procedures in a canine model of obstructive jaundice.

Outcomes of side-to-side conversion hepaticojejunostomy for biliary anastomotic stricture after right-liver living donor liver transplantation

BACKGROUND:Conversion hepaticojejunostomy is considered the salvage intervention for biliary anastomotic stricture,a common complication of right-liver living donor liver transplantation with duct-to-duct anastomosis,after failed endoscopic treatment.The aim of this study is to compare the outcomes of side-to-side hepaticojejunostomy with those of endto-side hepaticojejunostomy.METHODS:Prospectively collected data of 402 adult patients who had undergone right-liver living donor liver transplantation with duct-to-duct anastomosis were reviewed.Diagnosis of biliary anastomotic stricture was made based on clinical,biochemical,histological and radiological results.Endoscopic treatment was the first-line treatment of biliary anastomotic stricture.RESULTS:Interventional radiological or endoscopic treatment failed to correct the biliary anastomotic stricture in 13 patients,so they underwent conversion hepaticojejunostomy.Ten of them received end-to-side hepaticojejunostomy and three received side-to-side hepaticojejunostomy.In the end-to-side group,two patients sustained hepatic artery injury requiring repeated microvascular anastomosis,two developed restenosis requiring further percutaneous transhepatic biliary drainage and balloon dilatation,and two required revision hepaticojejunostomy.In the side-to-side group,one patient developed re-stenosis requiring further endoscopic retrograde cholangiography and balloon dilatation.No re-operation was needed in this group.Otherwise,outcomes in the two groups were similar in terms of liver function and graft survival.CONCLUSIONS:Despite the similar outcomes,side-to-side hepaticojejunostomy may be a better option for bile duct reconstruction after failed interventional radiological or endoscopic treatment because it can decrease the chance of hepatic artery injury and allows future endoscopic treatment if re-stricture develops.However,more large-scale studies are warranted to validate the results.

Hepaticojejunostomy with the “Hand-Fan” technique

A standard hepaticojejunostomy technique might be difficult to perform, especially when the bile duct is small and located deep in the liver hilum. Herein we present a new procedure, the Hand-Fan technique, that was used to enhance the exposure and ease the performance of these challenging anastomoses. Thirty-one patients who had had hepaticojejunostomy with this technique for bile duct injury and other benign biliary pathologies from July 2004 to June 2011 were included into the study. Median postoperative hospital stay was 7 days (6-25 days) and median follow-up time was 33 months (2-84 months). Liver function tests revealed that the blood bilirubin levels of the patients were normalized after hepaticojejunostomy. Follow-up showed that there were no signs of clinical recurrence or impaired bile flow. The Hand-Fan technique considerably facilitates challenging hepaticojejunostomies. Surgeon’s comfort is exceptional and the clinical results are satisfactory.

Endoscopic and retrograde cholangiographic appearance of hepaticojejunostomy strictures:A practical classifi cation

AIM:To study the endoscopic and radiological characteristics of patients with hepaticojejunostomy(HJ)and propose a practical HJ stricture classif ication.METHODS:In a retrospective observational study,a balloon-assisted enteroscopy(BAE)-endoscopic retrograde cholangiography was performed 44 times in 32 patients with surgically-altered gastrointestinal(GI)anatomy.BAE-endoscopic retrograde cholangio pancreatography(ERCP)was performed 23 times in 18 patients with HJ.The HJ was carefully studied with the endoscope and using cholangiography.RESULTS:The authors observed that the hepaticojejunostomies have characteristics that may allow these to be classif ied based on endoscopic and cholangiographic appearances:the HJ orif ice aspect may appear as small(type A)or large(type B)and the stricture may be short(type 1),long(type 2)and type 3,intrahepatic biliary strictures not associated with anastomotic stenosis.In total,7 patients had type A1,4 patients A2,one patient had B1,one patient had B(large orif ice without stenosis)and one patient had type B3.CONCLUSION:This practical classification allows for an accurate initial assessment of the HJ,thus potentially allowing for adequate therapeutic planning,as the shape,length and complexity of the HJ and biliary tree choice may mandate the type of diagnostic and thera-peutic accessories to be used.Of additional importance,a standardized classif ication may allow for better com-parison of studies of patients undergoing BAE-ERCP in the setting of altered upper GI anatomy.

Transoral outlet reduction:Outcomes of endoscopic Roux-en-Y gastric bypass revision in 284 patients at a community practice

BACKGROUND Transoral outlet reduction(TORe)is a minimally invasive endoscopic revision of Roux-en-Y gastric bypass(RYGB)for weight recurrence;however,little has been published on its clinical implementation in the community setting.AIM To characterize the safety and efficacy of TORe in the community setting for adults with weight recurrence after RYGB.METHODS This is a retrospective cohort study of argon plasma coagulation and purse-string suturing for gastric outlet reduction in consecutive adults with weight recurrence after RYGB at a single community center from September 2020 to September 2022.Patients were provided longitudinal nutritional support via virtual visits.The primary outcome was total body weight loss(TBWL)at twelve months from TORe.Secondary outcomes included TBWL at three months and six months;excess weight loss(EWL)at three,six,and twelve months;twelve-month TBWL by obesity class;predictors of twelve-month TBWL;rates of post-TORe stenosis;and serious adverse events(SAE).Outcomes were reported with descriptive statistics.RESULTS Two hundred eighty-four adults(91.9%female,age 51.3 years,body mass index 39.3 kg/m^(2))underwent TORe an average of 13.3 years after RYGB.Median pre-and post-TORe outlet diameter was 35 mm and 8 mm,respectively.TBWL was 11.7%±4.6%at three months,14.3%±6.3%at six months,and 17.3%±7.9%at twelve months.EWL was 38.4%±28.2%at three months,46.5%±35.4%at six months,and 53.5%±39.2%at twelve months.The number of follow-up visits attended was the strongest predictor of TBWL at twelve months(R^(2)=0.0139,P=0.0005).Outlet stenosis occurred in 11 patients(3.9%)and was successfully managed with endoscopic dilation.There was one instance of post-procedural nausea requiring overnight observation(SAE rate 0.4%).CONCLUSION When performed by an experienced endoscopist and combined with longitudinal nutritional support,purse-string TORe is safe and effective in the community setting for adults with weight recurrence after RYGB.

全内脏反位肝移植的研究进展

全内脏反位(SIT)是一种非常罕见的先天性疾病,在人群中发病率极低,不患病的SIT人群与普通人没有差别。但是当此类人群患病时,由于缺少对此类人群的认识,导致在对SIT人群进行诊断及治疗非常困难,尤其是SIT人群合并终末期肝病需要进行肝移植手术时,无论是SIT人群作为肝移植的供者或受者,对于外科医师而言都是巨大的挑战。本文通过查阅国内外近些年发表的SIT肝移植相关个案报道,对SIT肝移植在国内外的发展历程,SIT肝移植的关键步骤、预后及术后并发症等进行综述。

Comparison of long-term quality of life between Billroth-I and Roux-en-Y anastomosis after distal gastrectomy for gastric cancer: a randomized controlled trial

Background:The results of studies comparing Billroth-I(B-I)with Roux-en-Y(R-Y)reconstruction on the quality of life(QoL)are still inconsistent.The aim of this trial was to compare the long-term QoL of B-I with R-Y anastomosis after curative distal gastrectomy for gastric cancer.Methods:A total of 140 patients undergoing curative distal gastrectomy with D2 lymphadenectomy in West China Hospital,Sichuan University from May 2011 to May 2014 were randomly assigned to the B-I group(N=70)and R-Y group(N=70).The follow-up time points were 1,3,6,9,12,24,36,48,and 60 months after the operation.The final follow-up time was May 2019.The clinicopathological features,operative safety,postoperative recovery,long-term survival as well as QoL were compared,among which QoL score was the primary outcome.An intention-to-treat analysis was applied.Results:The baseline characteristics were comparable between the two groups.There were no statistically significant differences in terms of postoperative morbidity and mortality rates,and postoperative recovery between the two groups.Less estimated blood loss and shorter surgical duration were found in the B-I group.There were no statistically significant differences in 5-year overall survival(79%[55/70]of the B-I group vs.80%[56/70]of the R-Y group,P=0.966)and recurrence-free survival rates(79%[55/70]of the B-I group vs.78%[55/70]of the R-Y group,P=0.979)between the two groups.The scores of the global health status of the R-Y group were higher than those of the B-I group with statistically significant differences(postoperative 1 year:85.4±13.1 vs.88.8±16.1,P=0.033;postoperative 3 year:87.3±15.2 vs.92.8±11.3,P=0.028;postoperative 5 year:90.9±13.7 vs.96.4±5.6,P=0.010),and the reflux(postoperative 3 year:8.8±12.9 vs.2.8±5.3,P=0.001;postoperative 5 year:5.1±9.8 vs.1.8±4.7,P=0.033)and epigastric pain(postoperative 1 year:11.8±12.7 vs.6.1±8.8,P=0.008;postoperative 3 year:9.4±10.6 vs.4.6±7.9,P=0.006;postoperative 5 year:6.0±8.9 vs.2.7±4.6,P=0.022)were milder in the R-Y group than those of the B-I group at the postoperative 1,3,and 5-year time points.Conclusions:Compared with B-I group,R-Y reconstruction was associated with better long-term QoL by reducing reflux and epigastric pain,without changing survival outcomes.Trial Registration:ChiCTR.org.cn,ChiCTR-TRC-10001434.

Duct-to-duct biliary reconstruction after radical resection of Bismuth Ⅲ a hilar cholangiocarcinoma

At present, radical resection remains the only effective treatment for patients with hilar cholangiocarcinoma. The surgical approach for R0 resection of hilar cholangiocarcinoma is complex and diverse, but for the biliary reconstruction after resection, almost all surgeons use Roux-en-Y hepaticojejunostomy. A viable alternative to Roux-en-Y reconstruction after radical resection of hilar cholangiocarcinoma has not yet been proposed. We report a case of performing duct-to-duct biliary reconstruction after radical resection of Bismuth Ⅲa hilar cholangiocarcinoma. End-to-end anastomosis between the left hepatic duct and the distal common bile duct was used for the biliary reconstruction, and a singlelayer continuous suture was performed along the bile duct using 5-0 prolene. The patient was discharged favorably without biliary fistula 2 wk later. Evidence for tumor recurrence was not found after an 18 mo follow- up. Performing bile duct end-to-end anastomosis in hilar cholangiocarcinoma can simplify the complex digestive tract reconstruction process.
