摘要:

目的    评估腹腔镜全胃切除术中应用圆形吻合器与直线吻合器实施消化道重建的安全性和有效性。方法    回顾性分析自2012年3月至2016年4月期间北京大学肿瘤医院胃肠肿瘤中心一病区接受腹腔镜辅助或全腹腔镜全胃切除术的胃癌病人资料,比较采用不同吻合器类型病人临床病理特点、手术特点和术后恢复情况,采用Logistic回归分析判断术后并发症的危险因素。结果    共纳入72例病人,采用圆形吻合器行腹腔镜辅助重建47例,采用直线吻合器行全腹腔镜重建25例。两组病人年龄、性别、体重指数(BMI)、肿瘤大小、Lauren分型、分化程度及分期方面差异无统计学意义(P>0.05)。直线吻合器组病人接受术前治疗比例更低(4.0% vs. 27.7%,P=0.026)。圆形吻合器组和直线吻合器组中位手术时间分别为247 min和258 min,中位术中出血量分别为100 mL和50 mL,差异均无统计学意义(P>0.05)。手术根治程度、淋巴结清扫数目及近端切缘距离方面同样差异无统计学意义。直线吻合器组病人术后首次进全流食时间更短(3.5 d vs. 5.0 d,P=0.030),术后住院时间、术后首次排气时间、首次进半流食时间及术后首次拔除腹腔引流管时间差异无统计学意义。两组病人术后并发症发生率分别为25.5%和32.0%,差异无统计学意义(P=0.560)。病人临床病理特点及手术相关因素进行单因素分析均未提示和术后并发症相关。结论    应用机械吻合方法行腹腔镜全胃切除手术安全可行,直线吻合器进行全腹腔镜下和圆形吻合器腹腔镜辅助切口下进行消化道重建在手术时间、出血量、术后风险等方面相当,且直线吻合器组全腹腔镜下重建术后胃肠道功能恢复可能更快。

Abstract    Objective    To evaluate the safety and effectiveness of mechanical staplers in laparoscopic total gastrectomy. Methods    The clinical data of gastric adenocarcinoma patients who received laparoscopic-assisted or totally laparoscopic total gastrectomy in Gastrointestinal Cancer Center Ward I of Peking University Cancer Hospital from March 2012 to April 2016 was collected retrospectively. The clinical pathologic characteristics,operative features and postoperative recovery features were compared between patients with linear stapler (LS) and the ones with circular stapler (CS). Logistic regression was used to identify the risk factors of postoperative complications. Results    A total of 72 patients were enrolled in the study with 47 patients in the CS group and 25 patients in the LS group. The difference of age,gender,BMI,tumor size,Lauren classification,differentiation grade,and pathologic stage between the two groups were not significant statistically(P>0.05). The proportion of patients who received preoperative therapy were lower in the LS group (4.0% vs.27.7%,P=0.026). The difference of surgical time and intraoperative blood loss of OS group and LS group were not significant statistically (median surgical time:247min vs. 258min,median intraoperative blood loss:100mL vs. 50mL). There was no statistical difference in the extent of curative,retrieved lymph node number,and proximal margin distance between the two groups. On postoperative recovery,the first liquid diet time was shorter in the LS group (3.5d vs. 5.0d,P=0.030),but the postoperative hospital stay,first flatus time,first semi-liquid diet time and first abdominal drainage tube removing time were same statistically between the two groups. The rates of postoperative complications were 25.5% and 32.0% in CS group and LS group (P =0.560),and no risk factor was identified in regression model. Conclusion    For laparoscopic total gastrectomy,mechanical staplers are safe. The surgical time,intraoperative blood loss and postoperative risk of linear stapler are comparable to those of circular stapler,and gastrointestinal function recovery may be faster in linear stapler group.
