腹腔镜辅助与开腹胃癌根治术的配对设计队列研究

目的:评价腹腔镜辅助全胃切除术(laparoscopic-assisted total gastrectomy,LATG)及D2淋巴结清扫术的可行性、安全性、肿瘤根治性及术后早期疗效。方法:回顾分析为32例胃癌患者行腹腔镜辅助全胃根治术的临床资料,以性别、年龄、体重指数、ASA评分、术前总蛋白、白蛋白、血红蛋白、术前是否接受新辅助化疗、UICC(1997)分期、肿瘤部位、病理组织学类型及Bormann分型为指标,用逐一配对法选择同期32例传统开腹手术作为对照,比较两组的手术安全性、术后恢复及肿瘤的根治性。结果:32例均成功完成腹腔镜手术,无中转开腹。27例施行LATG(D2),1例行腹腔镜辅助全胃联合胰体尾切除术(D2),5例行腹腔镜辅助姑息全胃切除术。腹腔镜组平均手术时间(220.78±44.34)min,开腹组(178.44±29.06)min(P<0.05)。腹腔镜组平均切口长度、术后肛门排气时间及进食时间分别为(5.50±0.57)cm,(3.63±1.04)d,(3.94±0.84)d,显著低于开腹组。腹腔镜组术后第1天白细胞及中性粒细胞计数分别增加(6.61±2.92)×109/L,(7.32±3.01)×109/L,第3天白细胞及中性粒细胞分别增加(3.99±3.83)×109/L,(4.48±3.94)×109/L,显著低于开腹组。腹腔镜组淋巴结清扫总数、第1及第2站淋巴结数分别为(26.41±13.71)、(17.13±9.13)及(9.22±8.16)枚,与开腹组差异无统计学意义。腹腔镜组切口感染率低于开腹组,肺部感染率高于开腹组,但差异无统计学意义;两组其他并发症及总的并发症发生率差异亦无统计学意义。术后近期随访效果良好。结论:LATG比传统开腹手术时间长,但能达到与开腹根治性全胃切除术(D2)相同的淋巴结清扫范围,且具有患者创伤小、术后急性期反应轻、术后康复快等优势,LATG安全、可行、微创。

A matched cohort analysis of laparoscopic-assisted total gastrectomy versus conventional open total gastrectomy for gastric cancer

Objective:To evaluate the feasibility,safety and short-term outcomes of laparoscopic-assisted total gastrectomy(LATG)with D2 lymphadenectomy for gastric cancer.Methods:The clinical data of 32 patients with gastric cancer who were treated by LATG was retrospectively analyzed.These patients were then compared with a cohort of 32 patients with gastric cancer treated by conventional open total gastrectomy(OTG).They were matched in respect of sex,age,Body Mass Index,the American Society of Anesthesiologists phys...
