Laparoscopic Sleeve Gastrectomy versus Laparoscopic Roux-en-Y Gastric Bypass in Management of Morbid Obesity: Midterm Results in a Single Center

Objective: Laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) are widely used surgical procedures for morbid obesity. The objective of the study was to present the mid-term results of our first LSG and LRYGB cases. Material and Method: We retrospectively reviewed LSG and LRYGB patients treated at Samsun Training and Research Hospital, Turkey, within the period from January 2016 to December 2020. The demographic data of patients, comprising age, gender, body mass index (BMI), obesity-related diseases, and medications, were registered. The percentage total weight loss (%TWL), percentage excess weight loss (%EWL), and postoperative BMI were evaluated, and the results of both groups were compared. Results: The LSG and LRYGB groups comprised 19 and 43 patients, respectively. Of these, 50 were female and 12 were male. The average age in the LSG group was 30.89 ± 7.56 years, whereas in the LRYGB group it was 42.56 ± 12.18 years (p < 0.05). The mean %EWL was 72.35 ± 35.24 and 76.08 ± 22.84, and the mean %TWL was 30.46 ± 13.37 and 34.70 ± 11.31, respectively (p  0.05). BMI was 31.84 ± 8.76 in the LSG group and 30.14 ± 5.05 in the LRYGB group (p  0.05). B12 and Fe deficiency were observed in LRYGB cases, with a significant difference found between the groups. The mean follow-up was 50.47 ± 10.93 months in the LSG group and 52.21 ± 11.58 months in the LRYGB group (p  0.05). Conclusion: LSG and LRYGB are two bariatric surgical procedures that are safe and effective with adequate weight loss in the medium term. Monitoring for B12 and Fe deficiency is important in patients undergoing LRYGB.
