Comparative effectiveness of Roux-en-Y gastric bypass and sleeve gastrectomy in achieving diabetes remission in patients with diabetes-related vascular diseases: A multicentred study.

Metabolic and bariatric surgeries (MBS), including Roux-en-Y Gastric Bypass (RYGB) and Sleeve Gastrectomy (SG), have proven effective in promoting long-term diabetes remission among patients with type-2 diabetes (T2D). In this multicentre retrospective cohort study, we investigated the effectiveness of RYGB and SG in achieving diabetes remission, specifically among patients with T2D and vascular complications, while accounting for similar baseline diabetes severity. Although various scores predict diabetes remission after bariatric surgery, they do not consider diabetes-related vascular complications, which can influence outcomes even in patients with similar baseline T2D severity.

American Society for Metabolic and Bariatric Surgery Review of Body Composition.

Although the body mass index (BMI) has been used as a measure of obesity for decades, it is now possible to measure adiposity more directly with technologies that can quantitate body fat and other tissues. The purpose of this review is to understand body composition, describe the different ways to measure it, review changes in body composition after metabolic and bariatric surgery (MBS), and provide guidance on how providers can introduce measurements of body composition into their everyday practice.

Biliopancreatic diversion with duodenal switch results in superior weight loss and diabetes remission in patients with baseline body mass index ≥50.

Background: Patients with body mass index (BMI) ≥50 have more obesity-associated medical problems and often require more aggressive surgical management. Few single-institution comparative studies have been published examining this specific population.

Objectives: The study aims to compare the weight loss and diabetes remission effects of sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and biliopancreatic diversion with duodenal switch (BPD/DS).

A high adherence level to nutritional recommendations minimizes protein and minerals loss while maximizes visceral fat loss in bariatric surgery patients.

Background: Metabolic bariatric surgeries are considered the finest and most appropriate treatment option for patients with severe obesity. Besides the surgical procedure, many factors appear to be associated with improved postoperative outcomes such as compliance to the postoperative diet and supplementation, regular physical activity, medical and nutritional follow-up, and modifications in dietary habits.

Objectives: The objectives of this study were to investigate the effect of adherence to postoperative recommendations on anthropometric measurements and body composition and assess the percentage of total weight loss (%TWL) and excess weight loss (%EWL) 3 months postoperative.

Background: Obstructive sleep apnea (OSA) is the most common sleep-related breathing disorder associated with multisystem organ involvement. The STOP-BANG questionnaire is a short and valid questionnaire used to screen OSA. This study aimed to investigate the ability of the STOP-BANG questionnaire to predict postoperative OSA- related respiratory complications in patients undergoing bariatric surgery.

Surgical Complications Following Appendectomy in Obese Patients: A Single Tertiary Care Center Study.

Background The escalating global prevalence of obesity raises concerns about its implications for health outcomes. While obesity is acknowledged as a major risk factor for various diseases, its impact on appendicitis and appendectomy outcomes remains less explored. Methods Data on overweight and obese adults aged 18 to 65 treated for appendicitis in King Abdulaziz Medical City in Riyadh, Saudi Arabia were collected retrospectively.

Needlescopic Laparoscope Sleeve Gastrectomy (NLSG): a Potential Surgical Approach.

Background: Laparoscopic sleeve gastrectomy has become the most popular weight loss surgery currently, but it inevitably leaves multiple small scars in the abdomen. Although the appearance of single-incision laparoscopic sleeve gastrectomy achieve better cosmetic results, it may lead to postoperative complications such as umbilical hernia and umbilical infection. The author has developed a new surgical approach that can compensate for these deficiencies, which we called needlescopic laparoscope sleeve gastrectomy (NLSG).
