直肠癌是我区常见的恶性肿瘤之一。以往直肠癌根治术,皆采用定型的 Miles氏手术方法。近几年来,我们在临床工作中,由于部份患者拒绝行人工肛门术,对有适应症者改行保留部份肛门括约肌及部份直肠粘膜、直肠乙状结肠拉出术,类似改良Bacon氏法,经观察报导于下: 一、手术方法简介:腹部手术:腹内操作与Miles氏相似。当打开腹腔后,检查腹腔各脏器及直肠癌情况,当确定可以行切除术时,应充分游离左结肠并超过脾曲甚至部分横结肠,在靠近乙状结肠动脉主干处结扎切断乙状结肠动脉下端二分支,使有足够长度的肠段供手术切除;依照肿瘤原则,游离直肠至最低 Rectal cancer is one of the common malignant tumors in our area. In the past, the radical Miles’ surgical method was used for radical rectal cancer surgery. In recent years, in our clinical work, because some patients refused to undergo artificial anal surgery, those with indications were diverted to retain some of the anal sphincter and part of the rectal mucosa, and the rectosigmoid pull-out procedure was similar to the modified Bacon method. Observations are reported below: First, Introduction to the surgical method: Abdominal surgery: The intra-abdominal operation is similar to that of the Miles. When the abdominal cavity is opened, check the peritoneal organs and rectal cancer. When it is determined that resection can be performed, the left colon should be fully freed from the splenic flexure and even part of the transverse colon. The sigmoid artery should be ligated at the main artery to cut off the lower branches of the sigmoid artery. Make a sufficient length of the bowel for surgical resection; according to the principle of tumor, free the rectum to the lowest
