Introduction: Using a smaller size of bougie during sleeve gastrectomy is assumed to have an impact on weight loss and complications. However, there is ongoing debate as to what the appropriate bougie size should be. In this study, we aimed to compare sleeve gastrectomies in patients who underwent surgery using a 34 Fr bougie versus a 60 Fr.
Methods: A retrospective analysis of a prospectively maintained database of laparoscopic sleeve gastrectomies (LSG) was performed between January 2006 and March 2015. Data analyzed included bougie size, weight loss, postoperative complications and long-term outcomes.
Results: 281 patients who had LSG were included, of which 200 (71.2%) were female. 179 had their operation with a 60 Fr. Bougie (63.7%). Mean age and body mass index (BMI) were 47.5 years (±11.5) and 44.2 kg/m2 (±3.9), respectively. Mean Follow up time was 22.83 months (±8.44). There was no difference in the 2 groups regarding Follow-up rates at 2 years. Basic demographics were the same, and the long-term results were similar between the groups. When looking at excess weight loss the mean was 59.8% (±26.6) in the 34f group in comparison to 52.5% (±24.6), p=0.03. No intraoperative complications or mortality occurred. 1 patient (0.3%) suffered short term complications (dehiscence), and 6 (2.1%) from long term complications (like gallbladder disease – 4, need for revision – 2 and hernia repair – 1).
Discussion and Conclusions: Controversy exists regarding technical aspects of LSG, including bougie size used to calibrate the sleeve. In our study, a smaller bougie size (34f) had a small improvement in excess weight loss at two years as compared to a larger bougie size (60f). There was no impact on short or long-term results and complications. Longer follow up is needed to determine if this small improvement in excess weight loss remains significant.
