Objective To investigate risk factors for and management of delayed gastric emptying (DGE) after gastrectomy. Method A retrospective analysis was made from 482 patients undergoing gastric resection. Result DGE occurred in 41 of 482 patients (8.5%), risk factors of DGE were diabetes (19%),malnutrition (10%), peritonitis(17%),age(≥60)(14%),gastrointestinal hemorrhage(15%), anastomotic leakage(33%). Subphrenic abscess (39%), pancratobiliary fistula(83%). Conclusion DGE is paticularly common in patients with diabetes、malnutrition with an age≥60. Postoperative risk factors include peritonitis、gastrointestinal hemorrhage、anastomotic leakage、subphrenic abcess, and pancreatobiliary fistula. Gastric motility resumed in 4 weeks in most patients. Need for reoperation for DGE is rare, total gastrectomy in this case is recommended.%目的探讨胃切除术后排空障碍的高危因素及治疗方法。方法对482例胃切除术病例进行回顾性分析。结果本组482例中有41例出现胃排空障碍,发生率为8.5%。胃切除术后排空障碍的高危因素有糖尿病(19%)、营养不良(10%)、腹膜炎(17%)、高龄(≥60岁)(14%)以及术后消化道出血(15%)、吻合口漏(33%)、膈下感染、脓肿形成(39%)、胆胰漏(83%)等。结论术前及术后存在的高危因素可能是胃切除术后排空障碍的原因。胃动力常在4周内恢复。如需再次手术,以全胃切除为宜。
