Background and Aim: Several risk factors affecting post-operative recurrence in Crohn's disease patients have been studied, and of these, the role of the anastomosis remains contentious. We aimed to compare the risk of developing early post-operative endoscopic recurrence (EPER), in resections that had an end-to-end anastomosis (ETEA) to a side-to-side anastomosis (STSA). Methods: All Crohn's disease patients that underwent an ileocolic or small bowel resection between January 2012 and June 2017 at two tertiary IBD centres were reviewed retrospectively. Included patients had a minimum of 12-month clinical follow-up and a colonoscopy within 12 months of the resection or stoma reversal. Univariate and multivariate binary logistic regression analyses determined the independent risk factors for early post-operative endoscopic recurrence, defined as a Rutgeerts score of ≥ i2b. Results: Ninety-two resections associated with an ETEA or a STSA were included for analysis. The ETEA was the most common anastomosis, constructed in 55 patients (59.8%). Forty-nine operations (53.3%) resulted in a ≥ i2b recurrence at the first surveillance colonoscopy. The multivariate analysis showed that there was no difference between the ETEA and STSA in determining the odds ratio (OR) for developing EPER (OR = 2.41 (0.95–6.05), P = 0.06). In those that underwent a resection emergently however, the significant determinants of EPER were as follows: having an ETEA (OR = 38.12 (2.44–595.87), P = 0.01), failing to commence a biologic and/or an immunosuppressant early (OR = 24.21 (1.69, 347.81), P = 0.02), and active smoking (OR = 7.19 (1.12–46.21), P = 0.04). Conclusion: The ETEA is best avoided in those undergoing an emergency resection. The early commencement of a biologic and/or an immunosuppressant and smoking cessation is imperative this high-risk group of patients. [ABSTRACT FROM AUTHOR]

Background: No consensus has been achieved on optimal perioperative strategies for patients undergoing endoscopic submucosal dissection (ESD). The aim of this study was to investigate the effects of an intravenous (IV) proton pump inhibitor (PPI) given during the fasting period after ESD on delayed bleeding following ESD.Methods: This study was designed as a prospective, randomized, double-blind, placebo-controlled trial in a single center. A total of 235 patients who underwent ESD for adenoma and early gastric cancer between March 2016 and September 2018 were randomized into a PPI group and placebo group. Patients were administrated intravenous pantoprazole 40 mg daily (PPI group) or placebo (placebo group) during the fasting period 48 h after ESD (from the day of ESD to the following day, 48 h). After oral feeding (48 h after ESD), oral PPI was given to both groups for 8 weeks.Results: Among 235 patients in the intention-to-treat (ITT) and 195 in the per-protocol (PP) analysis, there was no significant difference between the PPI and control groups in major bleeding (PPI vs. placebo; 3.3% vs. 1.7%, p = 0.27) or minor bleeding (PPI vs. placebo; 7.6% vs. 4.3%, p = 0.41) after ESD. There was no significant difference in age (p = 0.28), histology (p = 0.75), tumor size (p = 0.48), or procedure time (p = 0.49) between the two groups. The only independent risk factor for major delayed bleeding was the combined use of aspirin and antiplatelet agent (OR; 12.25, 95% CI; 1.06-141.19, p = 0.04).Conclusions: Administration of routine IV PPI during the fasting period 48 h after ESD does not reduce delayed post-ESD bleeding.

Background: Pancreatoduodenectomy is considered to be a very invasive treatment for early superficial duodenal tumors (SDTs), which have a lower risk of lymph node metastasis. Partial resection of the duodenum with endoscopic submucosal dissection for SDT resection is an attractive technique but it is associated with a high risk of complications. We describe our technique for SDT resection.Method: It includes the following elements: freeing the transverse mesocolon, exposing and mobilizing the second part of the duodenum and the head of the pancreas (Kocher maneuver), confirming the location of the ulcer bed for endoscopic submucosal dissection, and laparoscopic suturing by hand in the seromuscular layer of the duodenum. We performed this technique in 10 patients between March 2015 and March 2017.Results: The median tumor diameter and resected tissue diameter were 36 (20-54) and 41 (25-60) mm, respectively. Curative resection (R0) with negative margins was achieved for all patients. There were no conversions to open surgery in this series. No postoperative complications were above grade 2 in the Clavien-Dindo classification system. No recurrences were observed during the medium-term follow-up period.Conclusion: This technique is safe and feasible and can be an option for surgical SDT resection. [ABSTRACT FROM AUTHOR]

Purpose: Over the last 3 decades, laparoscopic procedures have emerged as the standard treatment for many elective and emergency surgical conditions. Despite the increased use of laparoscopic surgery, the role of laparoscopic repair for perforated peptic ulcer remains controversial among general surgeons. The aim of this study was to compare the outcomes of laparoscopic versus open repair for perforated peptic ulcer.Methods: A systemic literature review was conducted using Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. A search was conducted using MEDLINE, EMBASE, PubMed and Cochrane Database of all randomised controlled trials (RCT) that compared laparoscopic (LR) with open repair (OR) for perforated peptic ulcer (PPU). Data was extracted using a standardised form and subsequently analysed.Results: The meta-analysis using data from 7 RCT showed that LR for PPU has decreased overall post-operative morbidity (LR = 8.9% vs. OR = 17.0%) (OR = 0.54, 95% CI 0.37 to 0.79, p < 0.01), wound infections, (LR = 2.2% vs. OR = 6.3%) (OR = 0.3, 95% CI 0.16 to 0.5, p < 0.01) and shorter duration of hospital stay (6.6 days vs. 8.2 days, p = 0.01). There were no significant differences in length of operation, leakage rate, incidence of intra-abdominal abscess, post-operative sepsis, respiratory complications, re-operation rate or mortality. There was no publication bias and the quality of the studies ranged from poor to good.Conclusion: These results demonstrate that laparoscopic repair for perforated peptic ulcer has a reduced morbidity and total hospital stay compared with open approach. There are no significant differences in mortality, post-operative sepsis, abscess and re-operation rates. LR should be the preferred treatment option for patients with perforated peptic ulcer disease. [ABSTRACT FROM AUTHOR]

Background: The over-the-scope clip (OTSC) is a novel endoscopic tool that enables non-surgical management of gastrointestinal (GI) defects. The aim of this study was to report our experience with OTSC for patients with GI defects.Methods: A prospectively maintained IRB-approved institutional database was queried for all patients treated with OTSC from 2012 to 2015. Primary outcome was the clinical success of the OTSC for the individual indication. Secondary outcome was the number of additional procedures needed following OTSC.Results: Fifty-one patients were treated with OTSC: upper GI (UGI) 30 and lower GI (LGI) 21. GI leak (n = 24; UGI = 12, LGI = 12) and fistulae (n = 17; UGI = 8, LGI = 9) were the most common indications. Overall success rate for the treatment of leaks was 59 % [UGI 66 % vs. LGI 33 % (p = 0.1)]. A lower success rate (35 %) was noted for fistulae [UGI 62 % vs. LGI 0 % (p = 0.001)]. Success rates for UGI perforation, bleeding, and stent anchoring indications were 75, 75, and 50 %, respectively. Additional endoscopic or surgical interventions following OTSC were indicated in 68.6 % of the patients.Conclusions: OTSC appears to have additional value in treating UGI defects. However, lower success rates for LGI defects were noted, specifically for fistulae. Most patients require an additional endoscopic or surgical procedure after one OTSC application.

Aim: The clinical features of postoperative bleeding from the ileal pouch-anal anastomosis(IPAA) vary and its management can be difficult. There is no published literature regarding pouch bleeding and its treatment.Materials and Methods: Pouch bleeding was defined as the passage of blood or clots transanally or into the ileostomy bag with or without hypotension or a drop in hemoglobin within 30 days after surgery. Patients were identified from a prospectively maintained pouch database.Results: Pouch bleeding developed in 47 (1.5%) patients out of 3,194 patients undergoing IPAA since 1983. Forty-two patients had inflammatory bowel disease, four had familial adenomatous polyposis, and one had colonic inertia. Sixty-six percent of bleeding occurred within 7 days postoperatively and 59.6% required transfusion; 72.3% patients developed transanal bleeding, nine from ileostomy and two from both. After initial fluid resuscitation, five patients were observed while 28 patients had pouch endoscopy and clot evacuation followed by cauterization or epinephrine(1:100,000) enemas, 27 of these had cessation within 24 h. Epinephrine enema was used as initial treatment in the remaining 12 patients. Overall success rate of epinephrine enema was 96%.Conclusion: Postoperative pouch bleeding after IPAA is uncommon, and it usually requires nonsurgical intervention. Epinephrine enema appears to be successful in managing this complication. [ABSTRACT FROM AUTHOR]
