Abstract
IntroductionThe aim of the study was to evaluate preoperative factors associated with remission of diabetes and weight loss after laparoscopic gastric band surgery. Materials and methodsA retrospective cohort of 95 patients who had an adjustable gastric band placed were included. A preliminary descriptive study of prognostic factors was performed using the logistic regression model with SPSS 17.0. The independent variables were age, sex, body mass index (BMI), diabetes status, and degree of obesity; dependent variables were the proportion of weight loss, change in diabetes status score, and percent changes in fasting sugar and glycosylated haemoglobin. ResultsThe variables that were significantly associated with the percentage of changes in fasting blood sugar and glycated haemoglobin were: the degree of obesity in the first year; preoperative and diabetes status respectively. The analysis of the need for antidiabetic treatment using the modified diabetes status score showed preoperative BMI, age, and gender as significant predictors. ConclusionsIn patients undergoing gastric band surgery, weight loss is the fundamental mechanism by which insulin sensitivity increases. This improvement in glucose metabolism is influenced by factors such as sex, age, insulin treatment, duration of diabetes, and degree of preoperative obesity.
