Comparison of Laparoscopic Sleeve Gastrectomy (LSG) with Laparoscopic Gastric Bypass (LRYGB) in Bariatric Surgery.

Introduction The objective of our study was to compare the 30-day post-operative outcomes of laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB). Materials and Methods This randomized controlled study contained patients who underwent bariatric surgery from June 13, 2018 to October 12, 2019. A total of 116 patients having body mass index (BMI) > 35 kg/m (morbidly obese), age 18 to 65 years and with failure of conservative treatment were included. Group I patients underwent bariatric surgery using LRYGB technique while group II patients underwent bariatric surgery using the LSG technique. All patients were followed 30 days after surgery to determine early post-operative outcomes. Results The demographic profile, such as age and BMI, was similar between the groups. The mean operating time was 72 ±12 minutes in the LSG group and 156 ± 18 min in the LRYGB group (p-value 0.0001). Major complications were seen in five (8.62%) patients in LSG patients and in four (6.89%) patients in LRYGB group (p-value 0.12). Minor complications were seen in 21 (36.2%) patients in LSG group and in 19 (32.75%) patients in LRYGB group (p-value 0.15). The length of stay in the hospital in LSG group was 6.2±4.2 versus 9.4± 4.6 (p-value 0.0002). Conclusion Both LRYGB and LSG are effective and safe bariatric procedures with a similar incidence of major complications. However, LSG is associated with shorter operative time and hospital stay. Long-term follow-up studies are required to compare the effectiveness of these procedures.
