Abstract
Background and Aim: Sleeve gastrectomy (SG) is a rapid and comparatively simple bariatric operation, which thus far shows good resolution of co-morbidities and good weight loss. It is presently considered as effective as the current gold standard operation, the Laparoscopic Roux-en-Y gastric bypass (LRYGB). Most bariatric surgeons agree that standardization of sleeve gastrectomy diameter and hence volume with a bougie or orogastric tube is important. There is, however, no universal agreement regarding the ideal size of the bougie. We aim to evaluate the first-year outcome of LSG using two different bougie sizes.
Patient and Methods: The study was prospective comparative study on 60 cases of morbidly obese patients with different of BMI. The patients were from Ain Shams University bariatric clinic. The patients were randomly arranged in two groups, group 1 using bougie 36 Fr and group 2 using bougie 40 Fr. Follow up to patients was done up to one year as regard excess weight loos, complications mainly (leakage and stricture).
Result: Results: A total of 60 patients underwent LSG between March 2015 and March 2016. Patients had a mean age of 35 years. The mean preoperative weight was 133 ± 12.5 kg. The mean BMI was 46.66 ± 4.30 kg/m2. The mean BMI of group 1 and 2 at 6 months was 34.21 ± 3.85 kg/m² and 29.30 ± 3.48 respectively. The mean %EWL of group 1 and 2 at 12 months was 71.65 ± 11.06 kg/m2 and 67.76 ± 11.78 %, respectively. When stratifying the %EWL by bougie size (36F versus 40F), we did not find a significant difference at 6 months. We did find a significant statistical difference between the 2 groups is term of postoperative persistent vomiting.
Conclusion: Our data suggest that using 36 Fr or 40 Fr does not influence LSG first year weight loss. It indicates, however, that smaller bougie size resulted in significant persistent postoperative vomiting.
