Background The coronavirus disease 2019 (COVID-19) pandemic led to a worldwide suspension of bariatric and metabolic surgery (BMS) services. The current study analyses data on patterns of service delivery, recovery of practices, and protective measures taken during the COVID-19 pandemic by bariatric teams. Materials and Methods The current study is a subset analysis of the GENEVA study which was an international cohort study between 01/05/2020 and 31/10/2020. Data were specifically analysed regarding the timing of BMS suspension, patterns of service recovery, and precautionary measures deployed. Results A total of 527 surgeons from 439 hospitals in 64 countries submitted data regarding their practices and handling of the pandemic. Smaller hospitals (with less than 200 beds) were able to restart BMS programmes more rapidly (time to BMS restart 60.8 ± 38.9 days) than larger institutions (over 2000 beds) (81.3 ± 30.5 days) (p = 0.032). There was a significant difference in the time interval between cessation/reduction and restart of bariatric services between government-funded practices (97.1 ± 76.2 days), combination practices (84.4 ± 47.9 days), and private practices (58.5 ± 38.3 days) (p < 0.001). Precautionary measures adopted included patient segregation, utilisation of personal protective equipment, and preoperative testing. Following service recovery, 40% of the surgeons operated with a reduced capacity. Twenty-two percent gave priority to long waiters, 15.4% gave priority to uncontrolled diabetics, and 7.6% prioritised patients requiring organ transplantation. Conclusion This study provides global, real-world data regarding the recovery of BMS services following the COVID-19 pandemic. Graphical abstract

-Background -The increased prevalence of diverticular disease has made its most appropriate management a matter of constant debate. Especially for the cases of diverticulitis, considerable progress has been made in terms of diagnosis and management.The surgical resection of the involved colon is the only means of definitely eradicate this condition and so, the elective laparoscopic colectomy has emerged as a safe and interesting choice among the options of treatment. Aim -To analyze the outcomes of the laparoscopic left colectomy for diverticular disease performed over a 17-year period at a single institution. Methods -Between April 1990 and May 2007, a total of 205 consecutive left laparoscopic colectomies were retrospectively reviewed. Data obtained included the pre-operative workup, indications for surgery, operative results, complications and follow-up. Univariate and multivariate statistical analyzes were performed in an effort to identity risk factors for adverse outcomes in the series. Results -Indications were for non-complicated acute diverticulitis (80%), acute or chronic complicated diverticulitis (18.05%) and bleeding diverticular disease (1.95%). The conversion rate was 5.85% (12 cases). The median operative time was 180 (100-420) min with a hospital stay of 7 (5-44) days. The mean length of the resected specimen was 29.12 (+8.2) cm. Most cases (88.3%) had an unremarkable postoperative course but complications occurred in 24 (11.7%) patients. In order of frequency, these were: paralytic ileus (n=6), pelvic collections (n=4), bowel obstructions (n=4) and fistulas (n=2), among others. A re-operation was necessary in eight cases and there was one death (0.48%). Median follow-up was 26.5 (1-156) months with a satisfying result seen in 179 (87.32%) of the patients. In 18 (8.78%) cases, persistent symptoms of functional colonic disorders were noted. There were 7 (3.41%) anastomotic stenosis in witch two needed a re-operation. The recurrence rate was 1.95% (4 cases). Age and intraoperative complications were identified as risk factors for conversion. The presence of associated lesions was significantly correlated with the persistence of functional colonic symptoms during the follow-up. ConclusionsThe laparoscopic left colectomy is safe and effective in comparison to all other modalities of management for diverticular disease. Precise diagnosis and respect of the current indications are essential to achieve such results.RESUMO -Racional -O aumento da prevalência de doença diverticular tornou o seu manuseio mais adequado uma questão de debate constante.
