SADI-S 250 vs Roux-en-Y Duodenal Switch (RY-DS): Results of 5-Year Observational Study.

PURPOSE: There are only a small number of studies providing a comparison between SADI-S and Hess-Marceau's BPD/Duodenal Switch (RY-DS) operations. We aimed to compare 5-year results of SADI-S 250 (common limb 250 cm) with RY-DS. MATERIAL AND METHODS: Data of patients who underwent open SADI-S (n 226) and RY-DS (n 528) were retrospectively studied. EWL(%), EBMIL(%), TWL(%), antidiabetic effect, complications, and revision rate were compared between the two groups. RESULTS: After the first 12 months, EWL% (77.0% vs 73.3%) and TWL% (39.4% vs 38.9%) were statistically significantly better after SADI-S (p < 0.01, and p < 0.05 respectively), but not EBMIL% (p > 0.05). At nadir to 24-36 months, EWL, TBWL, and EBMIL after SADI-S was comparable to the RY-DS group. Up to the fourth and fifth year, better weight loss (TBWL, EBMIL, EWL) was observed after RY-DS than after SADI-S. Early complication rate was less (2.65%) in the SADI-S group vs 5.1% in the RY-DS. Protein deficiency and small bowel obstruction rates were also lower after SADI-S. 93.4% of patients achieved total remission of their diabetes. 7.5% of patients in the SADI-S group had symptoms of bile reflux, which was a main indication for revisions. CONCLUSION: SADI-S has many advantages over RY-DS. However, weight loss and antidiabetic effects after the third year were marginally lower after SADI-S compared to RY-DS. SADI-S is less dangerous in terms of malabsorption and looks to be a reasonable alternative to RY-DS as a metabolic operation. RY-DS could be implemented for weight regain and/or bile reflux after SADI-S.

The First Modified Delphi Consensus Statement for Resuming Bariatric and Metabolic Surgery in the COVID-19 Times.

The purpose of this study was to achieve consensus amongst a global panel of expert bariatric surgeons on various aspects of resuming Bariatric and Metabolic Surgery (BMS) during the Coronavirus Disease-2019 (COVID-19) pandemic. A modified Delphi consensus-building protocol was used to build consensus amongst 44 globally recognised bariatric surgeons. The experts were asked to either agree or disagree with 111 statements they collectively proposed over two separate rounds. An agreement amongst ≥ 70.0% of experts was construed as consensus as per the predetermined methodology. We present here 38 of our key recommendations. This first global consensus statement on the resumption of BMS can provide a framework for multidisciplinary BMS teams planning to resume local services as well as guide future research in this area.

Effectiveness of biliopancreatic diversion in the patients with bulimia nervosa.

BACKGROUND: Bulimia nervosa (BN) is an eating disorder, characterized by consumption of huge amounts of food during discrete periods. Unlike patients with binge-eating disorder (BED), patients with BN demonstrate elements of compensatory "purging" behavior to prevent weight gain and obesity: i.e. self-induced vomiting, use of laxatives and enemas. These habits may prevent patients from attaining morbid obesity (MO), but may seriously affect life-style and become an excruciating, sometimes life-threatening condition. METHODS: 6 of 108 patients (5.6%) who underwent BPD in our clinic (laparoscopic Scopinaro BPD - 1, open BPD/DS - 4, Lap. BPD/DS - 1) suffered from BN preoperatively. Their preoperative weight was 68-117 kg and BMI 27.6-41.9 kg/m(2). 4 of 6 patients had BMI <40 kg/m(2) before BPD but were MO in the past. The patient with the lowest weight had repeated gastroesophageal bleeding during self-induced vomiting. 3 of the 6 patients had previously failed intragastric balloon or Lap-Band. RESULTS: All 6 patients were cured or significantly improved of bulimic symptoms soon after BPD. Weight loss was very good and never reached an undesirably low level. Patient satisfaction was high. CONCLUSION: Severe BN may be considered as a latent and potentially malignant MO. BPD (or BPD/DS) may be an effective solution for some patients with severe BN, as a final decision after unsuccessful organized conservative attempts. All candidates for bariatric surgery should be screened for BN, because it may influence choice of procedure in favor to BPD or BPD/DS.
