Usefulness of laparoscopic surgery for colorectal cancer compared with open surgery

目的：腹腔镜手术在技术上对良性肿瘤和早期癌症都是可行的，但对于进展期结肠癌和早、晚期直肠癌还没有被广泛接受。本研究的目的是评价腹腔镜结直肠癌手术的近期和远期疗效。材料和方法：III期研究包括32例接受腹腔镜或传统开腹结肠癌手术的患者。II期研究包括16名接受腹腔镜直肠癌手术的患者。结果：III期研究显示，与开腹手术相比，腹腔镜术后出血少，排气快，术后住院时间短。术中、术后并发症发生率无明显差异。2例复发，无死亡病例。II期研究显示，无一例中转开腹手术，1例出现吻合口出血，2例出现伤口感染。结论：腹腔镜手术治疗结直肠癌安全可行，侵袭性小。需要进一步检查晚期结肠癌的长期预后。

Objectives : Laparoscopic surgery technically is feasible for both benign and early staged cancer, it has not been widely accepted for advanced colon cancer and early and advanced rectal cancer. The aim of this study was to evaluate the short and long-term results of laparoscopic surgery for colorectal cancer.Materials and Methods : A phase III study included 32 patients undergoing laparoscopic or conventional open surgery for colon cancer. A phase II study included 16 patients undergoing laparoscopic surgery for rectal cancer. A short and long-term results were evaluated.Results: A phase III study demonstrated that blood loss was less, flatus returned more quickly, postoperative hospital stay was shorter in patients with laparoscopic than those with open surgery. There were no differences of intraoperative and postoperative complications. There were two patients with recurrence and no patients died. A phase II study demonstrated that there were no patients with conversion to open surgery, one with anastomatic bleeding, two with wound infection.Conclusions : Laparoscopic surgery for colorectal cancer was feasible in terms of safety and less invasiveness. Further examination of long-term outcome for advanced colon cancer should be needed.
