Long-Term (7 Years) Follow-Up of Roux-en-Y Gastric Bypass on Obese Adolescent Patients (<18 Years).

Background: Few data are available about obesity surgery in adolescent patients. Objective: To assess long-term outcomes after laparoscopic Roux-en-Y gastric bypass (LRYGB) in patients Setting: University Hospital, Europe. Methods: A retrospective study of prospectively collected data of patients Results: 19 (12 females) of the 28 patients (67.9%) were available for follow-up. Preoperatively, 3 had type 2 diabetes mellitus (T2DM), 1 arterial hypertension, 5 dyslipidemia and 1 sleep apnea. In the ChG, average BMI after 7 years dropped from 38.9 kg/m2 preoperatively to 27.5 kg/m2. In the AdG, average BMI decreased from 39.4 to 27.1 kg/m2 in the same time period (nonsignificant between groups). One patient in the ChG needed a reoperation (internal hernia) versus 3 patients in the AdG (1 leak, 2 obstructions). All patients resolved their initial comorbidities. Two of 12 female patients in the ChG became pregnant 6 and 8 years after surgery, respectively, despite seemingly adequate oral contraception. Compliance with postoperative guidelines was good in 16/19 patients in ChG and in 14/18 patients in the AdG. Overall degree of satisfaction was high: 8.2/10 (SD 1.2, range 6-10) in the ChG and 8.9/10 (SD 1.7, range 5-10) in the AdG. Conclusion: LRYGB seems to be safe, provide good weight loss, and cure comorbidities in an adolescent population. Satisfaction degree is high. Inadvertent pregnancy despite conventional contraception is a possible issue.
