Objective To explore the diagnosis and treatment of gastroparasis syndrome after abdominal operation. Methods Clinical data of 25 cases with gastroparasis syndrome after abdominal operation from Jan 1995 to June 2006 were analysed retrospectively. Results Gastrectomy and nongastrectomy amounted to 16 and 9 cases( portal-azygous vein disconnection in 4 cases, panceaticoduodenectomy in 1 case, partial small intestinectomy and adhesions lysis in 1 case, radical excision of colon carcinoma in 2 cases, choledocholithotomy in 1 case). Gastroparasis syndrome characterized by upper abdominal distension, nausea, vomiting after clipping the pipe or large quantity of gastric drainage after operations. Gastrointestinal series and gastroscopy confirmed functional delayed gastric emptying. All cases recoverd through non-operative therapy including fasting, continuous gastrointestinal decompression, total parenteral nutrition or enteral nutrition, adn administration of gastro-intestinal dynamic medicine. Conclusions Gastroparasis syndrome is the common complication after abdomianl operation, gastrointestinal series, gastroscopy are main diagnostic methods, conservative medication obtains good effect.
