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/m2), 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/m2) 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.
