ABSTRACT
Objective To study the etiology,diagnosis and treatment of functional delayed gastric emptying(FDGE) resulting from pancreatoduodenectomy.Methods From June,1990~June,2003,136 patients received pancreatoduodenectomy,whose clinical data were retrospectively analyzed.Upper gastrointestinal(radiography) and endoscopy were the main methods of examination.Results Twenty-eight cases were(complicated) with FDGE in the 136 patients(20.6%) after operation.The occurrence of FDGE was(correlated) with hyperbilirubinemia,diabetes,duodenal obstruction,pancreatic fistula and abdominal infection.All patients were cured with conservative treatment.The recovery time of gastric motility was 14-42 days,average time was 28 days.Conclusions Hyperbilirubinemia,diabetes,duodenal obstruction,pancreatic(fistula) and abdominal infection were the main causes of FDGE.
