作者报告1993年10月至今10例经腹腔镜途径的腹腔镜直乙结肠切除术.男7例,女3例,年龄39～63岁.直肠腺瘤伴乙结肠憩室1例,直己结肠多发性腺瘤1例,高位直肠癌4例,乙结肠癌4例.Duke’s分期为A期1例石期4例C期3例,其中2例C期病人因肥胖及肿瘤太大而中转剖腹手术.手术方法为:气管插管全麻,膀胱截石位,建立气腹后用宽头电凝剪打开侧后腹膜,显露输尿管注意勿损伤,分离直肠后间隙骶前至尾骨尖前面打开腹膜返折,如需要切开两侧侧韧带,于肿瘤远端5cm处置腹腔镜切割缝合器离断结肠,接着解剖肠系膜下血管根部,同样用缝合器切断血管.将近端结肠连同肿瘤一起从左下腹3cm小切口处拉出切断,近端结肠置人吻合器抵钉座后重新放人腹腔,建立气腹,从肛门内伸人端端吻合器与抵钉座对合后击发完成吻合. The authors report 10 cases of laparoscopic straight sigmoid resection of the laparoscopic approach since October 1993. 7 males and 3 females, aged 39-63 years old. Rectal adenoma with bicolate diverticulum 1 case, multiple colon glands There were 1 case of tumor, 4 cases of high rectal cancer and 4 cases of B colon cancer. Duke’s stage was A stage 1 case of stone and 4 cases of C stage 3 cases, 2 cases of C stage were converted to laparotomy due to obesity and tumor was too large. Methods: Intubation general anesthesia, bladder lithotomy position, after the establishment of pneumoperitoneum with a wide open coagulation scissors to open the lateral posterior peritoneum, exposed ureter do not pay attention to injury, the separation of rectal space after the fistula to the front of the coccyx tip to open the peritoneal fold, If you need to cut the ligaments on both sides, treat the laparoscopic scissors at the distal 5cm of the tumor and then dissect the root of the inferior mesenteric vessel. Also use a suturer to cut off the blood vessels. Place the proximal colon together with the tumor from the left lower abdomen by 3cm. At the incision, the incision was made and the proximal colon was placed into the staple holder and the celiac cavity was reinserted. The pneumoperitoneum was established, and the anastomosis was performed after the anastomosis between the mandibular end stapler and the anvil stapler.
