Obesity Surgery: Focus on Sleeve Gastrectomy, Mini-Gastric Bypass, and Gastric Bypass Surgeries

Dear Colleagues,

Obesity is classified as one of the most severe global public health problems. Over 2.1 billion adults worldwide are considered overweight or obese; 640 millions of these are classified as obese. Bariatric surgery has proven to be an effective treatment strategy in treating obesity and improving associated comorbidities. At present, the most commonly conducted bariatric surgical procedures are Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG) and mini-gastric bypass (MGB).

Consensual indications for bariatric surgery are BMI ≥ 40 kg/m², BMI ≥ 35 kg/m² with T2D or other comorbidities that could be significantly improved after bariatric surgery.

Bleeding, leakage and gastric fistulae are the most common intraoperative complications and post-operative complications following bariatric procedures.

Literature reports a wide range of post-bariatric surgery complications, with a frequency ranging from 1% to 29%. Most common post-operative complications reported include leakage, haemorrhage, fistula, surgical site infection, abscess, gastric dilatation, stricture, wound complication and nutritional deficiencies.

The aim of this Special Issue is to compare the techniques most used in bariatric surgery, to observe how the complication and morbidity rate for each procedure changes.
