目的：探讨腹腔镜技术在结肠癌根治性手术中的作用。方法：对腹腔镜下结肠癌手术19例与开腹结肠癌手术20例患者手术时间、术中失血量、切缘肿瘤细胞阳性情况、术中淋巴结清扫数，及术后的需要止痛的时间、禁食时间、术后住院时间、术后排气时间、术后下床时间、导尿管留置时间进行比较。结果：实验组手术时间、术中失血量、需要止痛的时间、禁食时间、术后住院时间分别为172.5±15.4min、100.5±10.2ml、1.3±0.4d、3.3±0.8d、8.9±1.8d，3.2±1.1d，3.8±1.4d，3.3±0.5d对照组分别为155.4±16.5m i n、187.5±50.2m l、2.5±0.6d、5.0±1.2d、12.9±1.4d ,4.16±0.9d ,5.9±2.4d ,6.7±0.4d两组比较，存在统计学差异（P＜0.05）。在淋巴结清扫数、切缘阳性率、两组间比较无统计学差异（P＞0.05）。结论：腹腔镜技术在结肠癌根治术中起到减少术中出血，缩短禁食时间，缩短住院时间的作用。“,”Objective: To explore the effect of Laparoscopic technology radical operation in colorectal cancer. Methods: 19 cases were chosen to be studied who underwent radical resection by laparoscopic and 20 by open surgery in our department. To compare operation times, intraoperative blood losses, the positive situation of tumor cells on the cut edge, the number of intraoperative lymph node dissection, and postoperative need analgesic time, abrosia time. hospitalization time. Results: The results of the experiment group of The operative time, intraoperative blood loss, need analgesic time, abrosia time ,post-operative hospitalization time, first flatus time, time of postoperative out-of-bed activity, time of urinary catheterization were 172.4±15.4 min, 100.±10.2 ml, 1.3±0.4 day, 2.3±0.5 day, 8.9±1.8,3.2±1.1 d,3.8±1.4 d ,3.3±0.5 d day respectively. By contrast, those in control group were 155.4±16.5 min, 187.5 ±10.2 ml, 2.5±0.6 day, 5.0±1.2 day, 12.9±1.4, 4.16±0.9d, 5.9±2.4d, 6.7±0.4d day. There was statistical y significant between the two group (P0.05). Conclusion: the laparoscopic technique in colon carcinoma radical operation may reveal the effects of reduction of intraoperative bleeding in surgery, shorten the fasting time and shorten the hospitalization time.
