Objective: Single anastomosis duodeno-ileostomy with sleeve gastrectomy (SADI-S) is a powerful form of bariatric surgery; however, it has a high risk of malnutrition. Single anastomosis sleeve ileal (SASI) bypass with sleeve gastrectomy may be used as an alternative procedure to avoid malnutrition associated with SADI-S; however, no comparison between the two procedures has been performed.

Methods: Sprague-Dawley rats with diabetes (n = 32) were divided into four groups: SADI-S (n = 8), SASI (n = 8), SG (n = 8), and SHAM (n = 8). Body weight, food intake, and fasting blood glucose were measured, and the oral glucose tolerance test (OGTT) and insulin tolerance test (ITT) were performed before and after surgery. Blood samples were collected before and after the surgery to assess the levels of glucagon-like peptide-1 (GLP-1), hemoglobin, albumin, vitamin B12, calcium, and iron.

Results: The SADI-S and SASI groups showed significantly greater weight loss and better glucose control than the SG group postoperatively. The SADI-S and SASI groups showed similar improvements in glucose control throughout the study. The SADI-S and SASI groups had significantly higher GLP-1 levels than the SG group at 6 months. The SADI-S and SASI groups presented with various degrees of deficiencies, with the SADI-S group showing a higher risk for hypoalbuminemia and iron deficiency than the SASI group.

Conclusions: The SASI procedure may be a better alternative as it has excellent bariatric and metabolic results with lower risk for hypoalbuminemia and can be easily converted into either SADI-S or SG procedures. Nevertheless, further clinical results are needed.

Development and Validation of an Artificial Intelligence-Based Model to Predict Gastroesophageal Reflux Disease After Sleeve Gastrectomy.

Authors:
Sameh Hany Emile Waleed Ghareeb Hossam Elfeki Mohamed El Sorogy Amgad Fouad Mohamed Elrefai

Obes Surg 2022 May 21. Epub 2022 May 21.

Gastrointestinal Surgery Centre, Mansoura University, Mansoura, Egypt.

Purpose: Prediction of the onset of de novo gastroesophageal reflux disease (GERD) after sleeve gastrectomy (SG) would be helpful in decision-making and selection of the optimal bariatric procedure for every patient. The present study aimed to develop an artificial intelligence (AI)-based model to predict the onset of GERD after SG to help clinicians and surgeons in decision-making.

Materials And Methods: A prospectively maintained database of patients with severe obesity who underwent SG was used for the development of the AI model using all the available data points. Read More

Nonsteroid anti-inflammatory drugs and the risk of peptic ulcers after gastric bypass and sleeve gastrectomy.

Authors:
Martin L Skogar Magnus Sundbom

Surg Obes Relat Dis 2022 Apr 11. Epub 2022 Apr 11.

Department of Surgical Sciences, Uppsala University, Uppsala, Sweden.

Background: Pharmacologic pain treatment is common among bariatric patients. Nonsteroid anti-inflammatory drugs (NSAID) are not recommended after Roux-en-Y gastric bypass (RYGB) because of the increased risk of marginal ulceration, but the connection with NSAID is not unambiguous.

Objectives: Examine the association between NSAID exposure and peptic ulcers after primary laparoscopic RYGB and sleeve gastrectomy (SG) respectively. Read More

Vertical Sleeve Gastrectomy Lowers SGLT2/Slc5a2 Expression in the Mouse Kidney.

Section of Cell Biology and Functional Genomics and Imperial Diabetes Network, Division of Diabetes, Endocrinology and Metabolism, Imperial Centre for Translational and Experimental Medicine, Department of Medicine, Imperial College London, London W12 0NN, United Kingdom.

Bariatric surgery improves glucose homeostasis but the underlying mechanisms are not fully elucidated. Here, we show that the expression of sodium glucose cotransporter-2 (SGLT2/Slc5a2) is reduced in the kidney of lean and obese mice following vertical sleeve gastrectomy (VSG). Indicating an important contribution of altered cotransporter expression to the impact of surgery, inactivation of the SGLT2/Slc5a2 gene by CRISPR/Cas9 attenuated the effects of VSG, with glucose excursions following intraperitoneal injection lowered by ∼30% in wild-type mice but by ∼20% in SGLT2 null animals.

Background: revisional bariatric surgery is gaining increasing interest as long term follow-up studies demonstrate an elevated failure rate of primary surgery due to insufficient weight loss, weight regain or complications. This particularly concerns restrictive bariatric surgery which has been widely adopted from the '80s till present through different procedures, notably vertical banded gastroplasty, laparoscopic adjusted gastric banding and sleeve gastrectomy. The aim of this study is to define which revisional bariatric procedure performs the best after failure of primary restrictive surgery. Read More
