Laparoscopic Sleeve Gastrectomy Vs. One Anastomosis Gastric Bypass in Adolescents with Obesity.

OBJECTIVE: Large studies comparing outcomes between laparoscopic sleeve gastrectomy (LSG) and one anastomosis gastric bypass (OAGB) are scarce and involve adult populations. The aim of the study was to compare perioperative, early postoperative, and one-year postoperative outcomes of adolescents with obesity who underwent LSG or OAGB surgery.

METHODS: The medical records of adolescents with obesity who underwent LSG or OAGB at the Tel Aviv Sourasky Medical Center from January 2017 to January 2021 were retrospectively reviewed. Data on their gastrointestinal (GI) symptoms and postoperative quality of life were obtained by a telephone interview.

RESULTS: Included were 75 adolescents (median [interquartile range, IQR] age 17.3 [16-18] years) of whom 22 underwent OAGB and 53 underwent LSG. There were no significant preoperative group differences in age, sex, and body mass index score. A low rate of perioperative (5.7 % vs. 0) and postoperative complication (15.1% vs. 10 %) with no statistical differences between LSG and OAGB group, respectively, was noted. At 12 months, the precent excessive weight loss + IQR was 42.40% [30.00, 45.00] and 38.00% [33.550, 44.20] in the LSG and OAGB. group, respectively (P = NS). The results of the PedsQL Gastrointestinal Symptoms scale revealed significantly less food limitation and heartburn after OAGB compared to LSG (food limitation 71.63 vs. 53.85 and heartburn 83.654 vs. 61.6, P = 0.03 and P = 0.029, respectively).

CONCLUSIONS: Both surgeries are effective and safe for weight loss in the adolescent population. OAGB was associated with significantly fewer GI symptoms compared to LSG.
