title: Sleeve gastrectomy leads to easy management of hormone replacement therapy and good weight loss in patients treated for craniopharyngioma.
abstract: The aim of this study is to investigate the effects of sleeve gastrectomy on hormone replacement therapy and on hypothalamic obesity in patients affected by craniopharyngioma with post-surgical pan-hypopituitarism. A retrospective review of three patients, treated for hypothalamic obesity with laparoscopic sleeve gastrectomy, who have previously undergone surgery for craniopharyngioma in their childhood, was done. Patients' mean age and BMI were 22.3 years (range 21-24) and 49.2 kg/m2(range 41.6-58.1), respectively. The mean time of delay between neurosurgery and bariatric surgery was 12.3 years (range 6-16). There were no major complications or deaths. At 24 months follow-up, the mean BMI was 35.3 kg/m2(range 31.2-40.6). No hydrocortisone and sex steroids dose changes were observed, while levothyroxine was decreased in two patients. Growth hormone replacement therapy was increased in two patients, whereas it was started in one patient. Desmopressin was significantly decreased in all of them. Patients with surgically induced pan-hypopituitarism after craniopharyngioma who become obese, can expect good results from sleeve gastrectomy: this procedure does not have significant negative effects on hormone substitution and leads to a good stabilization of body weight in a mid-term follow-up.
