Bariatric surgery in morbidly obese adolescents: long-term follow-up

Abstract

Objective: Morbid obesity is an increasingly common disease in the industrialized world and poses a great challenge to the medical community. Many obese adolescents have undergone various conservative treatment methods without adequate success so that a surgical approach became necessary. We report on 18 patients who underwent bariatric surgery as well as a long-term follow-up program.

Methods: Eight patients received a laparoscopic adjustable gastric banding (LAGB). Four of these had to undergo a gastric bypass surgery (GByp) as second procedure due to insufficient weight loss. Nine patients primarily received a gastric bypass.

Results: LAGB: Mean weight loss after 24 months was 20 ± 6.3 kg. Four of the patients showed a regain in weight leading to a mean weight loss of 9 kg compared to initial weight after 53.3 months mean in this group. These patients had to undergo an additional gastric bypass procedure and lost 31 ± 18.3 kg after 18 months. GByp: Mean weight loss in nine patients after gastric bypass (primary procedure) was 31 ± 10.2 kg after 12 months and 36 ± 30.1 kg at the end of the observation time. Sleeve: Initial weight in this patient was 232 kg with a weight loss of 38 kg after 24 months.

Discussion and conclusion: It is remarkable that in four of eight patients who underwent LAGB had to undergo a second surgical procedure (GByp). No previous indicator, neither from a psychological nor from a medical point of view, could be detected. More long-term studies including psychological aspects seem to be necessary.
