Laparoscopic sleeve gastrectomy (LSG) remains the most common bariatric metabolic surgery procedure worldwide, according to the fourth international federation for the surgery of obesity and metabolic disorders global registry report in 2018 [Nevertheless, insufficient weight loss or weight regain (WR) has been reported in up to 30% of patients after LSG [When we look at sleeve dilatation, this may be an essential cause of WR because of the loss of restriction over time, which allows more food intake [What is often considered for revision surgery in WR after LSG is conversion to RYGB, conversion to biliopancreatic diversion with duodenal switch, or conversion to single anastomosis duodenal-ileal bypass. Nevertheless, several studies have found that revisional re-LSG after weight regain following primary LSG is a good option that may achieve effective sufficient weight loss and improve associated medical problems [To stimulate weight loss after bariatric-metabolic surgery, a banded laparoscopic sleeve gastrectomy (BLSG) can be initiated, which involves inserting a band around the upper part of the sleeve pouch to prevent its expansion and maintain better weight loss [For patients with weight regain and a large stomach volume, laparoscopic re-sleeve (re-LSG) can be considered a revisional option with good secondary results regarding weight loss [Some studies reported significantly higher weight loss in the BLSG cohort than in the non-banded LSG (NBLSG) cohort. Others reported that weight loss was comparable after BLSG or after RYGB [Sleeve volume by radiological assessment is a useful tool to report sleeve dilatation. This volumetric assessment can correlate dilatation and weight loss after LSG and BLSG [
