Metabolic changes following gastroplasty in Prader-Willi syndrome--a case report.
A vertical banded gastroplasty was performed in an adult female patient with Prader-Willi syndrome in an attempt to prevent the metabolic deterioration caused by polyphagia. After her operation, the patient felt satiated with the scheduled amount of food and one month later, her fasting blood sugar concentration (FBS) decreased from 521 to 125 mg/dl, and her urinary sugar excretion (US) from 257 to 9 g/day. Both glucose tolerance and insulin secretion were also improved. However, these parameters subsequently became worse after dietary control was lost since the surgical procedure alone was unable to continue to suppress the insatiable desire to eat food. Both her glucose tolerance and insulin secretion by the 31st postoperative month were better than before the surgery, but worse than at one month after the surgery. At the end of the surgery, but worse than at one month after the surgery. At the end of the 34th postoperative month, even under the temporary administration of 0.625 mg/day of glibenclamide, her FBS was 158 mg/dl and US, 38.1 g/day. Her body weight had also increased to over her preoperative value. Based on these results, we conclude that the effect of gastroplasty to prevent metabolic deterioration in our patient with Prader-Willi syndrome gradually diminishes.
