Bariatric surgery for morbid obesity in craniopharyngioma

Objective To retrospectively analyse the effectiveness of bariatric surgery for hypothalamic obesity in patients with craniopharyngioma (CP). Patients Patients who developed morbid obesity after surgery for CP and who underwent laparoscopic gastric banding (LAGB), laparoscopic sleeve gastrectomy or gastric bypass were included (n = 9). Patients with common obesity who underwent bariatric surgery served as controls (LAGB n = 40, sleeve gastrectomy n = 49 and gastric bypass n = 54). Results CP was diagnosed during childhood or adolescence [median (range) 10 (1–21) years] and age at bariatric surgery was 17 [12–30] years. Six patients underwent gastric banding [median follow‐up 5·5 years (range 1–9)], 4 had a sleeve gastrectomy [median follow‐up 2 (0·4–4) years] and two patients had gastric bypass surgery (median follow‐up 3 years). Three patients had more than one type of bariatric surgery. Different from controls, no weight loss was observed after LAGB or sleeve gastrectomy. The two patients who had gastric bypass surgery lost body weight comparable with controls. Conclusion With LAGB and sleeve gastrectomy, no significant loss of body weight was achieved in young adult patients with craniopharyngioma‐associated morbid obesity.
