Relationship between gastric pouch and weight loss after laparoscopic sleeve gastrectomy

Abstract

No statistical correlation was found between the volume of the gastric pouch and weight loss (percent EBL) after LSG in symptomatic or with unsatisfactory weight loss patients.

Dilatation of Sleeve Gastrectomy: Myth or Reality?

“…In the same way, Barbiero et al recently reported that the presence and the volume of a saccular dilatation of the cranial portion of the sleeve assessed by upper GI studies more than 1 year after surgery did not affect weight loss [7]. Braghetto et al did not find any association between the increase in residual gastric capacity at 2 years, assessed by barium or CT scan, and weight regain [7]. Karcz et al presented the results of banded LSG with a silicone ring that has been described as an option to counteract sleeve dilatation, but they failed to demonstrate an influence on weight loss in the first year of follow-up [20].…”

“…Data are presented as arithmetic means ± standard error of mean early weight loss failure following LSG. In the same way, Barbiero et al recently reported that the presence and the volume of a saccular dilatation of the cranial portion of the sleeve assessed by upper GI studies more than 1 year after surgery did not affect weight loss [7]. Braghetto et al did not find any association between the increase in residual gastric capacity at 2 years, assessed by barium or CT scan, and weight regain [7].…”

“…Indeed, most candidates for redo surgery after weight loss failure following LSG exhibit gastric dilatation [6]. However, the few available studies analyzing gastric volume evolution following LSG failed to demonstrate a strong relationship between gastric sleeve dilatation and weight loss failure [7][8][9]. Currently, the putative mechanisms involved in gastric dilatation following LSG are mostly patient's eating habits, an upper posterior gastric pouch incompletely dissected, and the natural history of LSG [6], but they remain controversial.…”

Correlation Between Preoperative Gastric Volume and Weight Loss After Laparoscopic Sleeve Gastrectomy

“…Weight loss after LSG appears to be multifactorial, despite volume restriction being the key factor. 19 , 20 The impact of residual sleeve volume after LSG on weight loss has been investigated. A high residual gastric volume (RGV) three years after LSG was a risk factor for failure.…”

Can Gastric Specimen Measurements Defines the Laparoscopic Sleeve Gastrectomy Outcome?

“…We have encountered a number of studies that were evaluating the gastric specimen measurements (2,4,5,13). Most of the studies in the literature have taken into consideration that the gastric specimen volume as an independent factor affecting the EWL% (4-6).…”
