Abstract
Background Metabolic surgery induces rapid remission of type 2 diabetes mellitus (T2DM). There is a paucity of high level evidence comparing the efficacy of the laparoscopic Roux-en-Y gastric bypass (RYGB) and the laparoscopic one-anastomosis gastric bypass (OAGB) in glycemic control. Also, the mechanisms that drive the conversion of T2DM in severe obese subjects to euglycemia are poorly understood. Methods The DIABAR-trial is an open, multi-center, randomized controlled clinical trial with 10 years follow-up which will be performed in 220 severely obese patients, diagnosed with T2DM and treated with glucose-lowering agents. Patients will be randomized in a 1:1 ratio to undergo RYGB or OAGB. The primary outcome is glycemic control at 12 months follow-up. Secondary outcome measures are diverse and include weight loss, surgical complications, psychologic status and quality of life, dietary behavior, gastrointestinal symptoms, repetitive bloodwork to identify changes over time, glucose tolerance and insulin sensitivity as measured by mixed meal tests, remission of T2DM, presence of non-alcoholic fatty liver disease/non-alcoholic steatohepatitis in liver biopsy, oral and fecal microbiome, cardiovascular performance, composition of bile acids, and the tendency to develop gallstones. Discussion The DIABAR-trial is one of the few randomized controlled trials primarily aimed to evaluate the glycemic response after the RYGB and OAGB in severe obese patients diagnosed with T2DM. Secondary aims of the trial are to contribute to a deeper understanding of the mechanisms that drive the remission of T2DM in severe obese patients by identification of microbial, immunological, and metabolic markers for metabolic response and to compare complications and side effects of RYGB and OAGB. Trial registration ClinicalTrials.gov NCT03330756; date first registered: October 13, 2017.

Br J Surg 2021; 108:145-151. [PMID: 33711136 DOI: 10.1093/bjs/znaa055] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2020] [Revised: 08/24/2020] [Accepted: 09/28/2020] [Indexed: 11/14/2022]
Abstract
BACKGROUND Internal herniation is a well known and potentially life-threatening complication of laparoscopic Roux-en-Y gastric bypass (LRYGB). The aim of this study was to evaluate the benefit and harm of closing the mesenteric defects with clips during LRYGB to prevent internal herniation. METHODS This was a single-centre, single-blinded RCT. Patients eligible for LRYGB were randomized to surgery with or without closure of mesenteric defects with clips. The primary endpoint was the incidence of (intermittent) internal herniation after LRYGB with a minimum follow-up of 24 months. Secondary outcomes were duration of surgery, number of clips used, trocars and sutures used, postoperative pain measured by a visual analogue scale (VAS), and postoperative complications. RESULTS Between 13 August 2012 and 18 May 2017, 401 patients were randomized to closure (201) or non-closure (200) of mesenteric defects. Median follow-up for both groups was 59 months (range 8-67 and 16-67 months in non-closure and closure groups respectively). The cumulated risk of internal herniation after 2 years was 8.0 per cent in the non-closure group compared with 4.5 per cent in the closure group (hazard ratio (HR) 1.81, 95 per cent c.i. 0.80 to 4.12; P = 0.231). At 5 years, rates were 15.5 and 6.5 per cent respectively (HR 2.52, 1.32 to 4.81; P = 0.005). Closure of mesenteric defects increased operating time by a median of 4 min (95 per cent c.i. 52 to 56 min for the non-closure group and 56 to 60 min for the closure group; P = 0.002). There was no difference in postoperative blood transfusion rates and VAS scores between the groups. CONCLUSION Routine closure of the mesenteric defects in LRYGB with clips is associated with a lower rate of internal herniation. Registration number: NCT01595230 (http://www.clinicaltrials.gov).

Abstract
Studies on morbid obesity have shown remarkable improvement of diabetes in patients who have undergone bariatric operations. It was subsequently shown that these operations induce diabetes remission independent of the resultant weight loss; as a result, surgeons began to investigate whether operations for gastric cancer (GC) could have the same beneficial effect on diabetes as bariatric operations. It was then shown in multiple reports that followed that certain operations for GC were able to improve or even cure type 2 diabetes mellitus (T2DM) in GC patients. This finding gave rise to the concept of “oncometabolic surgery”, in which a patient diagnosed with both GC and T2DM undergo a single operation with the purpose of treating both diseases. With the increasing incidence of T2DM, oncometabolic surgery has the potential to improve the quality of life and even extend survival of many GC patients. However, because the GC patient population and the bariatric patient population are wildly different and because different GC operations have different properties, the effect of oncometabolic surgery must be carefully assessed and engineered in order to maximize benefit and avoid harm. This manuscript aims to summarize the findings made so far in the field of oncometabolic surgery and to provide an outlook regarding the possibility of oncometabolic surgery being incorporated into standard clinical practice.

Abstract
Complications in bariatric surgery are varied; they are severe at times but infrequent. They may be surgical or non-surgical, and may occur early or late. The goal of this systematic review is to inform and help the attending physician, the emergency physician and the non-bariatric surgeon who may be called upon to manage surgical complications that arise after adjustable gastric band (AGB), sleeve gastrectomy (SG), or gastric bypass (GBP). Data from evidence-based medicine were extracted from the literature by a review of the Medline database and also of the most recent recommendations of the learned societies implicated. The main complications were classified for each intervention, and a distinction was made between early and late complications. Early complications after AGB include prosthetic slippage or perforation; SG can be complicated early by staple line leak or fistula, and BPG by fistula, stenosis and postoperative hemorrhage. Delayed complications of AGB include intragastric migration of the prosthesis, late prosthetic slippage and infection, while SG can be complicated by gastro-esophageal reflux, and BPG by anastomotic ulcer and internal hernia. The analysis of available data allowed us to develop decisional algorithms for the management of each of these complications.

Abstract
Background. Controversies on the utility of laparoscopic mini gastric bypass (LMGB) in weight loss and type 2 diabetes mellitus (T2DM) control still exist. Methods. We conducted a comprehensive literature search of PubMed, EMBASE, and Cochrane Library. Review Manager was used to perform the meta-analysis and the weighted mean difference (WMD) and/or odds ratio with 95% confidence interval (95% CI) were used to evaluate the overall size effect. Results. The literature search identified 16 studies for systematic review and 15 articles for meta-analysis. Compared with LAGB, LSG, and LRYGB, LMGB showed significant weight loss [WMD, −6.58 (95% CI, −9.37, −3.79), P < 0.01 (LAGB); 2.86 (95% CI, 1.40, 5.83), P = 0.004 (LSG); 10.33 (95% CI, 4.30, 16.36), P < 0.01 (LRYGB)] and comparable/higher T2DM remission results [86.2% versus 55.6%, P = 0.06 (LAGB); 89.1% versus 76.3%, P = 0.004 (LAGB); 93.4% versus 77.6%, P = 0.006 (LAGB)]; LMGB also had shorter learning curve and less operation time than LRYGB [WMD, −35.2 (95% CI, −46.94, −23.46)]. Conclusions. LMGB appeared to be effective in weight loss and T2DM remission and noninferior to other bariatric surgeries. However, clinical utility of LMGB needs to be further validated by future prospective randomized controlled trials.

Abstract
BACKGROUND A well-known complication of laparoscopic Roux-en-Y gastric bypass surgery (LRYGB) is bowel obstruction due to internal herniation (IH). Evidence suggests that mesenteric defects should be closed during LRYGB to reduce the risk of IH. Therefore, surgeons are now closing mesenteric defects during LRYGB using sutures, clips, or fibrin glue. However, it has been reported that complications may arise due to the closure of mesenteric defects. The aim of this review was to summarize the reported possible complications associated with the closure of mesenteric defects during LRYGB. METHODS A literature search of PubMed and EMBASE was performed to identify studies related to the closure of mesenteric defects during LRYGB. The studies were screened for the listing of possible complications associated with the closure of mesenteric defects. This systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis recommendations. RESULTS Thirty studies complied with the inclusion criteria for our analysis, which included 21,789 patients. Reported complications related to closure of the mesenteric defects were: small bowel obstruction because of IH, kinking, and adhesions. IH occurred because of incomplete closure of the mesenteric defects in 1.4% of all patients, 1.2% by the antecolic approach, and 1.9% by the retrocolic approach, respectively. Kinking of the small bowel occurred in .2% of 1630 patients after closure of the mesenteric defects with clips and adhesion formation was found among 4.6% of 152 patients after closure of the mesenteric defects with nonabsorbable sutures. CONCLUSIONS The reported risk of complications caused by closure of the mesenteric defects during LRYGB seems low.
