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 uncut Roux-en-Y and Roux-en-Y reconstruction after distal gastrectomy for gastric cancer: A meta-analysis

AIM To compare uncut Roux-en-Y(U-RY) gastrojejunostomy with Roux-en-Y(RY) gastrojejunostomy after distal gastrectomy(DG) for gastric cancer.METHODS A literature search was conducted in Pubmed, Embase, Web of Science, Cochrane Library, Science Direct, Chinese National Knowledge Infrastructure, Wanfang, and China Science and Technology Journal Database to identify studies comparing U-RY with RY after DG for gastric cancer until the end of December 2017. Pooled odds ratio or weighted mean difference with 95% confidence interval was calculated using either fixed-or random-effects models. Perioperative outcomes such as operative time, intraoperative blood loss, and hospital stay; postoperative complications such as anastomotic bleeding, stricture and ulcer, reflux gastritis/esophagitis, delayed gastric emptying, and Roux stasis syndrome; and postoperative nutritional status(serum hemoglobin, total protein, and albumin levels) were the main outcomes assessed. Metaanalyses were performed using RevM an 5.3 software.RESULTS Two randomized controlled trials and four nonrandomized observational clinical studies involving 403 and 488 patients, respectively, were included. The results of the meta-analysis showed that operative time [weighted mean difference(WMD):-12.95; 95%CI:-22.29 to-3.61; P = 0.007] and incidence of reflux gastritis/esophagitis(OR: 0.40; 95%CI: 0.20-0.80; P = 0.009), delayed gastric emptying(OR: 0.29; 95%CI: 0.14-0.61; P = 0.001), and Roux stasis syndrome(OR: 0.14; 95%CI: 0.04-0.50; P = 0.002) were reduced; and the level of serum albumin(WMD: 0.71; 95%CI: 0.24-1.19; P = 0.003) was increased in patients undergoing U-RY reconstruction compared with those undergoing RY reconstruction. No differences were found with respect to intraoperative blood loss, hospital stay, anastomotic bleeding, anastomotic stricture, anastomotic ulcer, the levels of serum hemoglobin, and serum total protein. CONCLUSION U-RY reconstruction has some clinical advantages over RY reconstruction after DG.

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.

Roux-en-Y augmented gastric advancement: An alternative technique for concurrent esophageal and pyloric stenosis secondary to corrosive intake

Select group of patients with concurrent esophagealand gastric stricturing secondary to corrosive intake requires colonic or free jejunal transfer. These technically demanding reconstructions are associated with significant complications and have up to 18% ischemic conduit necrosis. Following corrosive intake, up to 30% of such patients have stricturing at the pyloro-duodenal canal area only and rest of the stomach is available for rather less complex and better perfused gastrointestinal reconstruction. Here we describe an alternative technique where we utilize stomach following distal gastric resection along with Roux-en-Y reconstruction instead of colonic or jejunal interposition. This neo-conduit is potentially superior in terms of perfusion, lower risk of gastro-esophageal anastomotic leakage and technical ease as opposed to colonic and jejunal counterparts. We have utilized the said technique in three patients with acceptable postoperative outcome. In addition this technique offers a feasible reconstruction plan in patients where colon is not available for reconstruction due to concomitant pathology. Utility of this technique may also merit consideration for gastroesophageal junction tumors.

Sleeve Gastrectomy Associated with Antral Lesion Resection and Roux-en-Y Antrojejunal Reconstruction

Obesity has been growing worldwide, reaching epidemic proportions. Bariatric surgery is the most effective and durable treatment for severe obesity and related diseases. Roux-en-Y Gastric Bypass (RYGB) and Sleeve Gastrectomy (SG) are the most frequently performed bariatric operations, with long-term good results, in terms of weight loss and comorbidities control. Gastroesophageal Reflux Disease (GERD) is commonly associated with obesity. In general, it precludes the indication of sleeve gastrectomy, since this technique has a refluxogenic potential, as shown in many studies. In such cases, RYGB is considered the best surgery, reaching good weight loss and gastroesophageal reflux disease control. The drawback of this technique is that it leaves the remnant stomach, the duodenum, and the proximal part of the jejunum inaccessible. Besides, RYGB makes transoral endoscopic access to the biliary tree impossible. For all these reasons, this bariatric technique is not indicated in cases of gastric polyposis, gastric dysplasia, or strong family history of cancer, among others. We report a case of a morbidly obese patient with intense GERD, for whom a RYGB was precluded due to her strong family history of cancer, even knowing that it would be the best choice for reflux disease control. Instead, SG was chosen, even knowing it could worsen the gastroesophageal reflux disease. The patient signed an informed consent, after being fully enlightened about the risks. During the surgery, a small subserosal whitish lesion was detected, near the pylorus, on the anterior wall of the antrum. Thinking in a Gastrointestinal Stromal Tumor (GIST), it was resected, with a 2 cm safety margin, leaving a 4 to 5 cm hole on the gastric wall. The decision to maintain the proposed sleeve gastrectomy was made, to avoid leaving a remnant stomach, in a patient with such a strong family history of cancer. In the area of the resected lesion, an intraoperative decision was made not to just close the big gastric hole, being afraid of causing some anatomic or functional disturbance in gastric emptying. Instead, we decided to use the gastric opening to construct a Roux-en-Y antrotrojejunal anastomosis, with a 50 cm alimentary limb and a 200 cm biliopancreatic limb. Accordingly, it was performed a sleeve gastrectomy, associated with an antrojejunostomy in a Roux-en-Y fashion. The patient had an uneventful postoperative course. In the second year, she achieved normal weight and good nutritional status, without gastroesophageal reflux symptoms complaints. Seriography study shows that most of the contrast material passes through the antrojejunal anastomosis, instead of the pylorus, while the duodenum is endoscopically patent. This case report shows an unexpected surgical finding that led to a tactic of adding a Roux-en-Y gastric bypass in the antrum, associated with a sleeve gastrectomy, a strategy that may be adopted in cases of morbidly obese patients with important GERD, for whom gastrointestinal exclusions are contraindicated. To confirm this hypothesis, controlled studies are needed.

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.

Proximal small intestinal bypass outperforms Roux-en-Y and jejunoileal bypass in glucose regulation in streptozotocin induced diabetic rats

BACKGROUND The efficacy of various bariatric surgeries varies in reducing blood glucose levels.Given the distinct mechanisms and anatomical alterations associated with each procedure,it is crucial to compare their glycemic control outcomes.We hypothesize that proximal small intestinal bypass(PSIB)is superior in blood glucose reduction over Roux-en-Y gastric bypass(RYGB)and jejunoileal bypass(JIB).AIM To compare the effectiveness of PSIB,RYGB,and JIB in lowering blood glucose.METHODS Rats with streptozotocin-induced diabetes were randomly divided into PSIB,RYGB,JIB,and sham-operated groups.Body weight,food intake,fasting blood glucose level,oral glucose tolerance test,insulin tolerance test,liver enzymes,and blood lipids were measured.RESULTS Postoperatively,only the JIB group had a lower body weight compared to the sham group.The food intake of the rats in all three surgical groups was significantly less than that in the sham group.Fasting blood glucose was reduced in all surgical groups and was lower in the PSIB group than in the RYGB and JIB groups.Glucose tolerance and insulin sensitivity improved in all three surgical groups compared to the sham group,but the improvement appeared earliest in the PSIB group.At six weeks postsurgery,the PSIB group showed a reduction in alanine transaminase levels and maintained a normal lipid profile.CONCLUSION PSIB demonstrated excellent hypoglycemic effects in the early postoperative period,and had better efficacy than RYGB and JIB.

目的:探讨腹腔镜Roux-en-Y胃旁路术对超重或肥胖合并食管裂孔疝患者的治疗效果。方法:回顾分析2012年11月至2019年12月为4例肥胖或超重合并食管裂孔疝患者行减重及代谢手术的临床资料及随访资料。结果:4例患者中2例超重合并2型糖尿病,2例肥胖合并糖尿病或糖耐量异常,均合并高血压及血脂异常。3例术前胃镜提示食管裂孔疝,其中2例合并反流性食管炎(洛杉矶分级B级),诊断为胃食管反流病。4例术中均探查明确食管裂孔疝。4例患者均行单纯Roux-en-Y胃旁路术,未对食管裂孔疝进行修补。术后随访2~11.5年。肥胖患者术后1年内体重下降明显,多余体重减少百分比分别为63.64%与70.59%。2例超重合并糖尿病患者分别于术后第6个月、5年时血糖升高,另1例肥胖伴糖尿病患者完全缓解。4例患者术后均未出现胃食管反流症状;1例轻度贫血;高血压均缓解,肝功、血脂未见异常。结论:单纯Roux-en-Y胃旁路术治疗肥胖合并食管裂孔疝患者可有效减轻体重,对于超重或肥胖伴随疾病有明显改善,是安全、有效的。

不同小肠旷置长度应用于Roux-en-Y胃旁路术的研究进展

小肠旷置是Roux-en-Y胃旁路术(Roux-en-Y gastric bypass,RYGB)的关键环节,然而小肠旷置的长度,依然没有统一意见。在实行精准医疗的当下,通过对病人的小肠长度进行精确测量,个体化的制定合适的小肠旷置长度,可以在达到更佳的手术效果的同时减少术后并发症的发生。此文将结合文献介绍RYGB中不同的小肠旷置长度对手术效果的影响,期望为未来的临床实践和研究设计提供新的思路。
