BackgroundLaparoscopic adjustable gastric banding (LAGB) is used as a bariatric procedure for more than 30 years, but there is still insuf ficient data regarding postoperative weightloss predicting factors.
ObjectiveWe carried out a prospective randomized study to compare two different bands (SAGB and Minimizer Extra) and aimed to find weightloss predicting factors. Methods A total of 103 morbidly obese patients underwent LAGB from January 2009 to January 2010. The SAGB was used in 49 and MiniMizer Extra in 54 patients. Weight loss was evaluated after 1 and 5 years. Factors which significantly correlated with per centage excess weight loss (%EWL) were used to build predicting regression models.
ResultsThe mean patient age was 45.9 ± 11.7 years, and mean preoperative body mass index (BMI) was 47.5 ± 7.3 kg/m 2 . A total of 90 (87.3%) patients completed the 5year followup. The mean overall excess weight loss after 5 years was 47.3 ± 29.7%, and there was no difference between SAGB and MiniMizer bands (47.3% vs 50.3%; p = 0.14). After 1 year, BMI ≤ 47 MiniMizer, pa tients demonstrated better weight loss results. %EWL was also significantly greater in >40yearold MiniMizer group patients (p =0.012) and remained significantly higher after 5 years (p = 0.035).
ConclusionsIn > 40yearold patient group better %EWL can be achieved by using MiniMizer Extra bands compared to SAGB. The con structed prognostic models could be used to predict %EWL after application of SAGB and MiniMizer bands.
