  • Effect of Modified Sleeve Gastrectomy on Ghrelin and Glucagon Like Peptide-1 in Rats with Diet Induced Obesity

    ObjectiveTo explore a surgery of effective weight loss concentrating on gut hormone release. MethodsWistar rats were fed with high-fat diet for inducing obesity and which randomly divided into sleeve gastrectomy plus decent jejunoileal bypass (SJB) group (n=12), sleeve gastrectomy (SG) group (n=12), and sham operation (SO) group (n=11), the body weight reduction, food intake, plasma ghrelin level, and glucagon like peptide-1 (GLP-1) level were compared among three groups. ResultsThere were no differences of the body weight and food intake before operation among three groups (Pgt;0.05). Compared with the SO group, the body weight descended and the food intake decreased obviously on 1-8 weeks after operation in the SJB group (Plt;0.05), the body weight of rats on 1-8 weeks after operation in the SJB group significantly descended as compared with the SG group (Plt;0.05), and the food intake of rats on week 3, 6, 7, and 8 in the SJB group signicantly decreased as compared with the SG group (Plt;0.05). There were no differences of the levels of the plasma ghrelin and GLP-1 before operation among three groups (Pgt;0.05). Compared with SO group, the plasma ghrelin level decreased and the GLP-1 level increased in the SJB group and the SG group, meanwhile the SJB group significantly decreased level of plasma ghrelin and elevated level of plasma GLP-1 as compared with the SG group on week 8 after operation(Plt;0.05). ConclusionThe data demonstrate that SJB could represent an effective way of losing weight by interfering with food intake and obesity related hormone levels.

  • Influence of Sleeve Gastrectomy on Blood Glucose, Ghrelin, and Glucagon Like Peptide-1 Levels in GK Rats

    ObjectiveTo investigate the effect and mechanism of sleeve gastrectomy (SG) on reducing blood glucose level. MethodsThirty GK rats were randomly divided into SG group, sham operation (SO) group, pair-fed (PF) group, and blank control (BC) group. The changes of weight, fasting blood glucose, glucose tolerance (oral glucose tolerance test, OGTT), insulin tolerance (insulin tolerance test, ITT), plasma insulin, ghrelin, and glucagon like peptide-1 (GLP-1) were monitored before and 24 weeks after operation respectively. ResultsFrom the 4th week after operation, weight gain in SG group and PF group began to decrease significantly compared with SO group (Plt;0.01). From the 2nd week after operation, fasting blood glucose level in SG group was lower than that in SO, PF, and BC groups (Plt;005), and the glucose tolerance in SG group obviously improved compared with preoperation and the other 3 groups (Plt;0.01). On the 6th week after operation, the insulin sensitivity in SG group obviously improved compared with SO group (Plt;0.05, Plt;0.01). There was no significant difference of insulin level between SG group and SO group (Pgt;0.05), ghrelin level significantly decreased (Plt;0.01) while GLP-1 level significantly increased (Plt;0.01) in SG group compared with SO group during 2-24 weeks after operation. ConclusionsThe effect of SG on reducing blood glucose is definite. SG can directly lower blood glucose independent with weight loss. Postoperative decreased ghrelin level and increased GLP-1 level may be its primary mechanism.

  • Chinese standardized surgical guideline for symmetrical three-port laparoscopic sleeve gastrectomy (2023 edition)

    Laparoscopic sleeve gastrectomy (LSG) is an effective and lasting method for treating obesity, type 2 diabetes and other obesity related metabolic diseases. The symmetrical three-port LSG has been proven to be a simple, safe, and effective surgical procedure. However, China still lacks standardized surgical operation guidelines for this method. This guideline provides a detailed description of the various steps and key details of the symmetrical three-port LSG, aiming to standardize and normalize the symmetrical three-port LSG in the bariatric and metabolic field in China, and to provide standardized surgical procedures for clinical surgeons in this field.
