Project description:Here, we describe the modified delta-shaped anastomosis (DSA) via the overlap method and how it was a beneficial intracorporeal anastomotic technique for four patients who underwent laparoscopic colectomy. After resecting the colon on both sides of the lesion, proximal and distal colon were laid in an overlap fashion and fixed using sutures. The entry hole was created using an ultrasound scalpel at a point 3 cm proximal to right colic stump and 7 cm distal to left colic stump on the anti-mesenteric side. Then, two arms of the linear stapler were inserted inside each lumen and fired. Finally, using the linear stapler, the common entry hole was closed in a delta-shaped manner. The mean duration of surgery was determined to be 218.4 (196-369) minutes, and amount of blood loss was measured to be 11 (5-25) mL. No intraoperative and postoperative complications were observed. Median postoperative hospital stay was 12 days. Thus, modified DSA via overlap method can be considered as a safe and simple IA technique.

Project description:BackgroundUlcerative colitis is an idiopathic inflammatory condition of the colon that may require surgical intervention including proctocolectomy and either ileal pouch-anal anastomosis or in the pediatric population, low ileorectal anastomosis (IRA). Often, subsequent physiologic alteration (or colonic metaplasia) occurs in the anastomosed small bowel that includes changes in mucin content, villous blunting, and increased expression of WNT5A, a marker of colonic crypt regeneration. We developed a rat low IRA model to assess and study the development of colonic metaplasia.Materials and methodsWe subjected male Sprague-Dawley rats (n = 17) to total colectomy and low IRA surgery and evaluated healing periodically by endoscopic evaluation. The ileum upstream of the anastomosis was assessed by hematoxylin and eosin staining, and the mucin content was measured by high iron diamine-Alcian blue staining. Wnt5a transcripts were quantified by reverse transcription and quantitative polymerase chain reaction at the 8-wk study end point.ResultsAlthough no gross endoscopic evidence of inflammation was seen throughout the course of the study, colonic metaplasia in the small bowel was detected in 7 out of 10 (70%) rats at the study end point. In rats with colonic metaplasia, enhanced expression of Wnt5a was evident at the study end point compared to levels in the terminal ileum at the time of surgery.ConclusionsWithin 4-8 wk, the majority of rats subjected to IRA developed colonic metaplasia defined by villous blunting, changes in mucin content, and increased expression of Wnt5a. This model provides a method to study small bowel colonic metaplasia.

Project description:BackgroundDelta-shaped anastomosis is a common method of intracorporeal gastroduodenostomy in totally laparoscopic distal gastrectomy. One common postoperative complication of this procedure is anastomotic stenosis, and endoscopic balloon dilatation is a major remedy for such complications. Other treatment strategies are necessary to manage unsuccessful endoscopic balloon dilatation.Case presentationWe present a case where systemic steroid treatment was applied in sustained anastomotic stenosis after endoscopic balloon dilatation. We performed delta-shaped anastomosis in laparoscopic distal gastrectomy to treat early-stage gastric cancer in a patient. The patient experienced abdominal pain post-surgery; subsequent investigation revealed edematous anastomotic stenosis. The stenosis sustained even after endoscopic balloon dilatation and local steroid injection. Consequently, we applied systemic steroid treatment.ConclusionSystemic steroid treatment improved the stenosis and no recurrence was observed. These results suggest that systemic steroid application could be useful to treat anastomotic stenosis.

Project description:BackgroundSelection of intracorporeal anastomosis (IA) or extracorporeal anastomosis (EA) in laparoscopic right colectomy (LRC) remains controversial. This meta-analysis aimed to evaluate the effectiveness and safety of IA compared with EA in LRC patients.MethodsLiterature was searched systematically for randomized controlled trials (RCTs) that compared IA with EA in LRC patients until May 2021. The eligible studies for risk of bias were assessed using the Cochrane Risk of Bias Tool. Data were extracted and analysed for the following outcomes of interest: operative time, length of incision, nodal harvest, bowel function recovery, postoperative pain, postoperative complications (wound infection, anastomotic leak, ileus, obstruction, reoperation), death at 30 days, duration of hospital stay and 30-day readmission.ResultsFive RCTs, including a total of 559 patients, were eligible for meta-analysis. All of the trials reported adequate random sequence generation and allocation concealment. There were significantly better outcomes in the IA group than in the EA group in time to first flatus (mean difference (MD) -0.71 (95 per cent c.i. -1.12 to -0.31), P = 0.0005), time to first passage of stool (MD -0.53 (95 per cent c.i. -0.69 to -0.37), P < 0.00001), visual analogue scale of pain on postoperative day (POD) 3 (MD -0.76 (95 per cent c.i. -1.23 to -0.28), P = 0.002), POD 4 (MD -0.83 (95 per cent c.i. -1.46 to -0.20), P = 0.01), POD 5 (MD -0.60 (95 per cent c.i. -0.95 to -0.25), P = 0.0007), length of incision (MD -1.52 (95 per cent c.i. -2.30 to -0.74), P = 0.0001) and wound infection (relative risk 0.46 (95 per cent c.i. 0.23 to 0.91), P = 0.02). However, there were no statistically significant differences between the two groups in duration of hospital stay (P = 0.47), operative time (P = 0.07), number of lymph nodes harvested (P = 0.70), anastomotic leak (P = 0.88), postoperative ileus (P = 0.48), bleeding (P = 0.15), bowel obstruction (P = 0.24), reoperation (P = 0.34), readmission within 30 days (P = 0.26), and death (P = 0.70).ConclusionCompared with EA, IA shows a faster recovery of bowel function with fewer wound infections.

Project description:BackgroundThere is still no consensus on the management of intraperitoneal anastomotic leakage after colonic surgery. Among of various treatment strategies, laparoscopic redo anastomosis for intraperitoneal leakage has rarely been reported in the literature and is condemned by some. The aim of this study is to demonstrate the feasibility and safety of laparoscopic redo anastomosis for intraperitoneal anastomotic leakage.MethodsRetrospective chart review of laparoscopic redo anastomosis for intraperitoneal anastomotic leakage after colonic surgery from January 2013 to May 2020. An accompanying video demonstrates the technique.ResultsFifteen consecutive patients underwent laparoscopic redo anastomosis for management of leakage after colonic surgery; two patients required conversion to open repair. A protective stoma was created in three patients during the second operation. There was no re-leakage nor mortality in this series.ConclusionsLaparoscopic redo anastomosis was feasible and safe for the management of intraperitoneal anastomotic leakage after colonic surgery. Considering the advantages of re-do laparoscopy, this procedure should be part of every surgeon's armamentarium to deal with anastomotic leakage and represents a logical alternative to the "Diversion and Drainage" technique.

Project description:BackgroundLaparoscopic colectomy is widely practiced for colon cancer, but many variations exist for anastomosis after laparoscopic colon cancer radical resection.MethodWe retrospectively analyzed 226 patients who underwent laparoscopic-assisted radical resection for left colon cancer with knotless hand-sewn end-to-end anastomosis (KHEA) technique with barbed V-loc™ suture material and compared perioperative outcomes, safety, and efficacy to those undergoing stapled anastomosis from 2010 to 2021.ResultsAfter the 1:2 propensity score matching, 123 participants with similar preoperative characteristics (age, body mass index, TNM stage, and tumor location) were enrolled in the study: 41 in the KHEA and 82 in the stapler group. Statistically significant differences were found in time to accomplish the anastomosis (mean 7.9 vs. 11.9 min, p < 0.001) and hospital costs (mean 46,569.71 vs. 50,915.35 CNY, p < 0.05) that differed between the KHEA and stapler group, respectively. No statistically significant difference was found in the mean delay to bowel function recovery (2.6 vs. 2.7 days, p = 0.466), duration of hospital stay (8.6 vs. 7.9 days, p = 0.407), or rate of postoperative complications (14.6% vs. 11.0%, p = 0.563). Anastomotic leakage occurred in 11 patients: 5 (12.2%) vs. 6 (7.3%) (p > 0.05) in the KHEA and stapler group, respectively.ConclusionKHEA is feasible and safe for anastomosis after laparoscopic left hemicolectomy. The KHEA technique could reduce operation time and hospital costs with complication rates comparable to stapling.

Project description:Introduction:Single-incision laparoscopic surgery (SILS) has benefits, including less postoperative pain, a shorter incision, and improved cosmesis. However, SILS is technically difficult because of the limited movement. An organ retractor is an instrument that has the potential to overcome these limitations. Presentation of case:An 85-year-old woman with hematochezia was referred to our hospital. Emergency endoscopy showed diverticulosis of the entire colon and active bleeding from the ascending colon. Despite endoscopic clipping, the bleeding continued. SILS total colectomy using an organ retractor was performed due to uncontrollable diverticular bleeding. A 3-cm incision was placed in the umbilicus, and three conventional ports were inserted into the single umbilical incision. An organ retractor was used for hepatocolic ligament transection, transection of the ileocolic vessels, and transection of the mesentery of the sigmoid colon. For each transection, the tension was adjusted to provide a good operative view. The patient's postoperative course was uneventful. Conclusion:An organ retractor was effective for SILS total colectomy to maintain an adequate operative view, which enabled safe dissection.

Project description:To investigate the safety and efficiency of using robotic staplers for intracorporeal gastroduodenostomy in reduced-port robotic gastrectomy for gastric adenocarcinoma. We retrospectively reviewed patients who underwent totally robotic and laparoscopic gastrectomy with intracorporeal gastroduodenostomy. Gastroduodenostomy using the ENDOWRIST robotic stapler (RR) was compared to that using an endolinear stapler during robotic gastrectomy (RE) and to that using an endolinear stapler during laparoscopic gastrectomy (LE). A total of 296 patients underwent gastroduodenostomy: 58, 28, and 210 patients with RR, RE, and LE, respectively. There were no conversions to other methods, and all robotic stapling procedures were performed on the console without receiving additional assistance from a bedside surgeon during RR. Comparing the operative outcomes of RR with those of RE and LE, respectively, we noted similar postoperative short-term outcomes. There were no major complications, including anastomosis-related complications, during the postoperative period after RR. The median reconstruction time during RR was 8 min and 45 s, which was similar to that during RE (8 min, 5 s [P > 0.9999]), but longer than that during LE (6 min, 30 s [P < 0.0001]). Intracorporeal gastroduodenostomy using the robotic stapler during robotic gastrectomy could be safely and feasibly performed on the console without the assistance of assistant, bedside surgeons.

Project description:Good short-term outcomes of intracorporeal ileocolic anastomosis (IIA) in totally laparoscopic colectomy for right-sided colon cancer (TLRC) have been shown in many reports, but no standardized technique for enterotomy closure after stapled side-to-side ileocolic anastomosis has so far been established. We retrospectively compared the short-term outcomes between 13 consecutive patients receiving either TLRC with IIA by conventional enterotomy closure (n = 6) or closure of the enterotomy using two barbed sutures (CEBAS) (n = 7) from July 2019 to April 2020. No anastomotic bleeding or leakage was observed in either group. Time to enterotomy closure was significantly shorter with the CEBAS method (16.5 ± 3.7 min) than with the conventional method (24.5 ± 4.7 min, p = 0.0059). The CEBAS method in TLRC with IIA was thus found to be technically feasible and it might reduce the stress associated with intracorporeal enterotomy closure.

Project description:BackgroundBillroth I (B-I) gastroduodenostomy is an anastomotic procedure that is widely performed after gastric resection for distal gastric cancer. A circular stapler often is used for B-I gastroduodenostomy in open and laparoscopic-assisted distal gastrectomy. Recently, totally laparoscopic distal gastrectomy (TLDG) has been considered less invasive than laparoscopic-assisted gastrectomy, and many institutions performing laparoscopic-assisted distal gastrectomy are trying to progress to TLDG without markedly changing the anastomosis method. The purpose of this report is to introduce the technical details of new methods of intracorporeal gastroduodenostomy using either a circular or linear stapler and to evaluate their technical feasibility and safety.MethodsSeventeen patients who underwent TLDG with the intracorporeal double-stapling technique using a circular stapler (n = 7) or the book-binding technique (BBT) using a linear stapler (n = 10) between February 2010 and April 2011 were enrolled in the study. Clinicopathological data, surgical data, and postoperative outcomes were analyzed.ResultsThere were no intraoperative complications or conversions to open surgery in any of the 17 patients. The usual postoperative complications following gastroduodenostomy, such as anastomotic leakage and stenosis, were not observed. Anastomosis took significantly longer to complete with DST (64 ± 24 min) than with BBT (34 ± 7 min), but more stapler cartridges were needed with BBT than with DST.ConclusionsTLDG using a circular or linear stapler is feasible and safe to perform. DST will enable institutions performing laparoscopic-assisted distal gastrectomy with circular staplers to progress to TLDG without problems, and this progression may be more economical because fewer stapler cartridges are used during surgery. However, if an institution has already been performing δ anastomosis in TLDG but has been experiencing certain issues with δ anastomosis, converting from δ anastomosis to BBT should be beneficial.
