Objective To summarize the clinical features,diagnosis and treatment principles of abdomen postsurgical gastroparesis syndrome(PGS).Methods The clinical data of 28 patients with abdomen postsurgical gastroparesis syndrome,collected from our hospital in the past ten years,were analyzed retrospectively.Results All 28 patients were cured by conservation therapy.The average gastric dynamics response time was 20.2 days(12.0～34.0 days),which included 2 cases recovered within 1-2 weeks,17 cases recovered within 2-3 weeks,7 cases recovered within 3-4 weeks,2 cases recovered over 4 weeks.Conclusion PGS is a functional reaction rather than mechanical obstruction disease.The diagnosis mainly depends on the symptoms and sighs combined with gastrointestinal angiography or endoscopy.Most of the patients can be cured by conservative treatment.
