The middle-term result of laparoscopic sleeve gastrectomy in Chinese obesity patients in a single hospital, with the review of literatures and strategy for gastric stenosis

Abstract

The aim of this study was to evaluate the medium-term metabolic results of laparoscopic sleeve gastrectomy (LSG) in Chinese patients. We performed a retrospective study of our LSG results between February 2011 and February 2015, and conducted a literature review of stenosis after LSG during a recent 10-year period. Of 142 patients in our study, the mean initial body mass index (BMI) was 38.34 kg/m2, the mean age of the patients (44 males and 98 females) was 29.36 years. All patients were followed up for at least 36 months. There was a significant reduction in BMI and blood lipid levels. For one case with gastric stenosis (0.7%), resolution was achieved by conversion to gastric bypass, with a satisfied result in weight loss and diabetes remission. The incidence of stenosis after LSG in previous studies was 0.1-3.5%. Among the cases of stenosis, 83.0% resolved with dilation, and the remainder resolved with a surgical procedure. LSG is a relatively safe surgical option for weight loss as a primary procedure in our study. Stenosis after LSG requires diagnosis and treatment promptly. Surgery can be a feasible treatment option, but care must be taken to avoid complications.
