Efficacy of non adjustable gastric band in excess weight loss outcomes and diabetes resolution in bariatric surgery

Background: Bariatric surgery is the most effective treatment for resolution of co-morbidities of obesity as well as weight loss. The concept of banding the neo-stomach in sleeve gastrectomy (LSG) and roux-en-y gastric bypass (LRYGB) was proposed to combat insufficient weight loss or weight regain due to pouch dilation. The aim of the study is to know the efficacy of non adjustable gastric band in weight loss outcomes of banded sleeve gastrectomy (BLSG) and banded roux-en-y gastric bypass (BLRYGB) and comparing them to the outcomes of LSG and LRYGB respectively. Materials and methods: This is retrospective analysis of all the patients who underwent bariatric surgery from January 2013 to December 2014 with 1 year follow-up. Data included age, height, weight, body mass index(BMI), gender, presence of type 2 diabetes mellitus(DM), fasting blood sugar (FBS), glycosylated hemoglobin(HbA1c), lipid profile, percentage excess body weight loss (%EBWL) and resolution of DM. Results: A total 230 patients (117females, 53males) were retrospectively analyzed. At one year follow up of LSG, BLSG, LRYGB and BLRYGB groups, %EBWL were 73.43±19.66, 82.41±26.33, 82.72±25.09 and 86.30±19.06 respectively. The BLSG group attained statistical significance (p=0.026) in bariatric success and %EBWL (p=0.021) on comparison to LSG group, but not BLRYGB to LRYGB. There was no statistical significance in DM resolution between banded and non banded procedures. Conclusions: Placement of non adjustable gastric band has significant weight loss outcomes after LSG, but not after LRYGB at 1 year follow up. In DM resolution there is no significance after band placement.
