由于涉及相关技术难题,腹腔镜手术在直肠癌治疗中的安全性和治疗效果一直受到争议,背离肠系膜切除这一肿瘤治疗原则可能增加局部复发率,缩短生存时间。为比较开腹与腹腔镜手术在直肠癌中的治疗效果,Lujan J等人在西班牙进行了一项前瞻性非随机多中心研究,非随机纳入4 970例直肠癌患者,比较分析其术前和术后的解剖病理及生存变量。排除565例患者后,剩余4 405例患者中,开腹组3 018例(68.51%),腹腔镜手术组1 387例(31.49%),后者的前切除比例更高。结果发现,
Due to the related technical problems, the safety and efficacy of laparoscopic surgery in the treatment of rectal cancer has been controversial. Deviation from the principle of mesenteric removal of the tumor may increase the local recurrence rate and shorten the survival time. To compare the therapeutic efficacy of laparotomy and laparoscopic surgery in rectal cancer, Lujan J et al. Conducted a prospective, nonrandomized multicenter study in Spain that randomized 4970 patients with rectal cancer and compared their preoperative and postoperative outcomes Postoperative anatomical pathology and survival variables. After excluding 565 patients, among the remaining 4 405 patients, 3 018 cases (68.51%) in the open group and 1 387 cases (31.49%) in the laparoscopic group, the latter had a higher proportion of resections. turn out,
