Background: Patients with compromised appendix base constitute a subgroup of patients with complicated appendicitis, and there is few available information., Objective: To study the frequency of stump leaks and fistulae in patients with complicated appendicitis with compromised stump., Method: This is an observational, retrospective study of patients that underwent laparoscopic appendectomy with compromised appendix stump., Results: From 2015 to 2019, 158 patients with complicated appendicitis were operated, of them 54 had compromised base or stump. There were 66.7% men, with a mean age of 38.7 years. For stump closure, a simple knot was employed in 57.4%, and in 42.6% an invaginated suture was employed. Regarding complications, 16.7% developed intraabdominal abscess, 7.4% ileus and 7.4% had wound infection. We found one stump leak and one stump fistula. The mean length of stay was 5.4 days (range: 1-20). There were 5 reoperations, 4 for abscess drainage and 1 for stump leak., Conclusions: Patients with acute complicated appendicitis with compromised appendicular base, laparoscopic surgery either with simple knot or with invaginated suture resulted in low frequency of stump leaks and fistula., (Copyright: © 2021 Permanyer.)

Background: Previous observational studies have demonstrated the safety of discharging patients after laparoscopic appendectomy within the same day without hospitalization. The application of Enhanced Recovery After Surgery (ERAS) guidelines has resulted in shorter length of stay, fewer complications, and reduction in medical costs. The aim of this study was to investigate if ERAS protocol implementation in patients with acute uncomplicated appendicitis decreases the length of stay enough to allow for ambulatory laparoscopic appendectomy., Methods: In this prospective, randomized controlled clinical trial, 108 patients were randomized into two groups: laparoscopic appendectomy with ERAS (LA-E) or laparoscopic appendectomy with conventional care (LA-C). The primary endpoint was postoperative length of stay. The secondary end points were time to resume diet, postoperative pain, postoperative complications, re-admission rate, and reoperation rate., Results: From January 2016 through May 2017, 50 patients in the LA-E group and 58 in the LA-C were analyzed. There were no significant differences in preoperative data. Regarding the primary end point of the study, the ERAS protocol significantly reduced the postoperative length of stay with a mean of 9.7 h (SD: 3.1) versus 23.2 h (SD: 6.8) in the conventional group (p < 0.001). The ERAS protocol allowed ambulatory management in 90% of the patients included in this group. There was a significant reduction in time to resume diet (110 vs. 360 min, p < 0.001) and less moderate-severe postoperative pain (28 vs. 62.1%, p < 0.001) in the LA-E versus LA-C group. The rate of complications, readmissions, and reoperations were comparable in both groups (p = 0.772)., Conclusions: ERAS implementation was associated with a significantly shorter length of stay, allowing for the ambulatory management of this group of patients. Ambulatory laparoscopic appendectomy is safe and feasible with similar rates of morbidity and readmissions compared with conventional care.

Background: Postoperative anastomotic leaks, bleeding and stenosis are major causes of morbidity after laparoscopic Roux-en-Y gastric bypass (LRYGB). Retrospective studies suggest that intraoperative endoscopy reduces the incidence of these complications., Methods: We conducted a prospective randomized controlled trial in a single institution between March 2013 and January 2016. Patients were assigned to one of two groups: LRYGB with Intraoperative Endoscopy (IOE) or LRYGB without IOE. Patient selection criteria were morbidly obese patients, 18 years or older who were candidates to LRYGB. The primary outcome was the frequency of technical defect related anastomotic leaks. Secondary outcomes were operative time, length of hospital stay, anastomotic related complications, reoperations and 30-day mortality., Results: 50 patients were randomly assigned in the IOE group and 50 in the control group. The IOE group had statistically significant lower rate of anastomotic leak (0 vs. 8%, p = .0412), and lower need for reoperation (0 vs. 8%, p = .0412). The IOE group had longer operative time (194.10 vs. 159 min, p < .001), and shorter mean length of hospital stay (2.44 vs. 3.46 days, p = .025). No differences were found in the rate of bleeding of the anastomosis, narrow anastomosis and 30-day mortality., Conclusion: This study specifically provides evidence that air leak test performed by intraoperative endoscopy is superior to simple visual inspection in preventing technical defect related leaks after laparoscopic Roux-en-Y gastric bypass., (Copyright © 2017.
