目的:研究腹腔镜辅助近端胃切除术(laparoscopic-assisted proximal gastrectomy,LAPG)和开腹全胃切除术(open proximalgastrectomy,OPG)治疗SiewertⅡ型和Ⅲ型食管胃结合部腺癌(adenocarcinoma of the esophagogastric junction,AEG)...目的:研究腹腔镜辅助近端胃切除术(laparoscopic-assisted proximal gastrectomy,LAPG)和开腹全胃切除术(open proximalgastrectomy,OPG)治疗SiewertⅡ型和Ⅲ型食管胃结合部腺癌(adenocarcinoma of the esophagogastric junction,AEG)的临床疗效。方法:回顾性分析蚌埠医学院第一附属医院2015年2月至2017年2月收治的116例行近端胃切除的SiewertⅡ型和Ⅲ型AEG患者的临床资料,其中LAPG组48例、OPG组68例。分析两组患者的临床病理特征、术中情况、根治效果与肿瘤复发情况。结果:两组患者手术均顺利完成,无围手术期死亡。LAPG组患者平均手术时间为(3.46±0.46)h,长于OPG组的(2.68±0.68)h;平均术中出血量为(108±46.8)mL,少于OPG组的(236±86.6)mL;胃肠功能恢复时间为(2.56±0.56)d,短于OPG组的(3.82±0.86)d;术后平均住院时间为(12.24±1.86)d,少于OPG组的(14.68±2.89)d;近端切缘(3.06±0.56)cm长于OPG组的(2.38±0.68)cm(均P<0.05)。两组患者的清扫淋巴结数目、远端切缘、术后并发症发生率,差异均无统计学意义(P>0.05)。结论:LAPG在治疗SiewertⅡ型和Ⅲ型AEG患者的根治效果、术后并发症及肿瘤复发方面与开放手术相当;LAPG具有术中出血少、胃肠功能恢复快、住院时间短的优势,近端切缘更长。展开更多
