title: Laparoscopic sleeve gastrectomy using 42-French versus 32-French bougie: the first-year outcome.
abstract: BACKGROUND
  The optimal size of bougie in laparoscopic sleeve gastrectomy (LSG) remains controversial. The aim of this study was to evaluate the first-year outcome of LSG using two different sizes of bougies.
  
  
  METHODS
  This study used a single institute retrospective case-control study of two groups of patients. Group A (N = 66) underwent LSG using 42-Fr and group B (N = 54) using 32-Fr bougies. A medication score was applied to assess the change in comorbid conditions.
  
  
  RESULTS
  Groups A and B's age (39.5 ± 12 vs. 43.6 ± 12.3 years), weight (119 ± 17 vs. 120 ± 20), and BMI (42.8 ± 3.8 vs. 43.6 ± 6.9 kg/m(2)), respectively, were comparable (p = NS). Comorbid conditions were type 2 diabetes (T2DM) in 19 (29%) vs. 23 (43%) patients, hypertension in 22 (33%) vs. 18 (33%) patients, and gastroesophageal reflux (GERD) in 28 (42%) vs. 10 (19%) patients, respectively. At 1 year, group A vs. B BMI was (29.4 ± 5 vs. 30 ± 5 kg/m(2)) and excess weight loss was 67 vs. 65%, respectively (p = NS). Postoperatively, T2DM (79 vs. 83%), hypertension (82 vs. 61%), and GERD (82 vs. 60%) (p = NS), respectively, in groups A vs. B did not require previous medications anymore. Complications were comparable.
  
  
  CONCLUSIONS
  Our data suggest that using a 42-Fr or 32-Fr bougie does not influence LSG first-year weight loss or resolution of comorbid conditions. Long-term data is needed to conclude this issue.
