[Risk factors associated with prolonged postoperative length of stay of patients with gastric cancer].

Objective: To investigate the risk factors of prolonged postoperative length of stay (LOS) in patients with gastric cancer. Methods: A retrospective study was performed on 2033 patients who underwent curative surgery in Department of Pancreatic-gastric, Cancer Hospital, Chinese Academy of Medical Sciences. Eightieth percentile of postoperative hospital stay for all patients was taken as the cutoff, the patients were divided into the normal group (1 532 patients) and the extended group (501 patients). Logistic regression model was used to determine the risk factors related to prolonged postoperative LOS in gastric cancer. Results: A total of 417 cases with postoperative complications were recruited in extended group. The five highest complications accounting for prolonged LOS were: abdominal infection in 69 cases (13.77%), pleural effusion in 60 cases (11.98%), anastomotic leakage in 43 cases (8.58%), poor wound healing in 34 cases (6.79%), and bleeding in 25 cases (4.99%). Logistic regression analysis showed that age (OR=1.348, P=0.013), surgical procedure (OR=2.712, P<0.001), extent of resection (OR=2.035, P<0.001), degree of incision healing(OR=4.867, P<0.001), and perioperative blood transfusion (OR=1.711, P<0.001) were independent risk factors for prolonged postoperative LOS. Conclusions: The most common complication associated with prolonged postoperative LOS for gastric cancer patients is abdominal infection. Age, surgical procedure, extent of resection, degree of incision healing, and perioperative blood transfusion are the independent risk factors for prolonged postoperative LOS.目的： 探讨胃癌患者术后住院时间延长的影响因素。 方法： 对中国医学科学院肿瘤医院胰胃外科行手术治疗的2 033例住院胃癌患者的临床资料进行回顾性研究，以全部患者术后住院时间的第80百分位数为界值，将患者分为术后住院时间正常组(1 532例)和延长组(501例)。采用多因素Logistic回归模型分析胃癌患者术后住院时间延长的影响因素。 结果： 术后住院时间延长组中，有417例出现术后并发症，术后并发症发生率居前5位的依次为腹腔感染69例(13.77%)，胸腔积液60例(11.98%)，吻合口漏43例(8.58%)，切口愈合不良34例(6.79%)，出血25例(4.99%)。Logistic回归分析显示，患者年龄(OR＝1.348，P＝0.013)、手术方式(OR＝2.712，P<0.001)、切除范围(OR＝2.035，P<0.001)、切口愈合等级(OR＝4.867，P<0.001)和围术期输血(OR＝1.711，P<0.001)是胃癌患者术后住院时间延长的独立影响因素。 结论： 胃癌患者术后住院时间延长的最常见并发症是腹腔感染。年龄、手术方式、切除范围、切口愈合等级和围术期输血是术后住院时间延长的独立影响因素。.
