我院在近10年的外科临床手术中,对4例因结肠肿瘤所致的腹部梗阻病人,于剖腹探查手术中,同期施行了结肠肿瘤急诊切除、结肠一期吻合术。手术所见:1例右半结肠中下段肿瘤和2例盲肠肿瘤,其肿瘤表面粘膜已糜烂溃破,腹腔有恶臭脓性分泌液。术后病理“粘液腺癌”。1例左半结肠肿瘤所致腹部梗阻患者术后病检为“腺癌”。以上4例因结肠痛所致腹部梗阻．患者,其癌细胞已穿透肠壁。周围结肠系膜淋巴结呈不同程度散在肿大。病理分期为“Dukes C_1”期。术中对3例右半结肠、盲肠癌患者,先将痛肿急诊切除后,再行右半结肠及所属系膜一并切除。残肠行回肠、结肠端侧一期吻合,1例左半结肠癌所致腹部梗阻患者,行癌肿和所属结肠系膜一并急诊切除后,其远段结肠切除断端缝合封闭,旷置腹腔,近段断端行左腹壁外置造瘘,结肠癌是最常见的内脏恶性肿瘤之一,与其它如鼻咽癌、食管癌、乳腺癌、宫颈癌等,具有临床表现的多样性和复杂多变的特性,常在许多治疗环节上防不胜防,结肠癌并腹部梗阻常于急诊剖腹探查手术中偶然发现,而同期同时施行结肠癌急诊一次性切除和结肠一期吻合,首先须注意腹腔、手术野清洁手术环境的建立、避免对肿瘤的一切不必要的盲目挤压、防止癌细胞经血道扩散、转移和腹腔脏、壁层腹膜、手术野粘膜、组织的种植、 In the surgical operation of our hospital for the past 10 years, 4 cases of abdominal obstruction due to colon cancer were undergoing exploratory laparotomy. At the same time, colonic neoplasm resection and colonic anastomosis were performed. Surgical findings: 1 case of the middle and lower segment of the right colon and 2 cases of caecal tumors. The surface of the tumor has become ulcerated and ulcerated, and there is a stinking purulent exudate in the abdominal cavity. Pathological “mucinous adenocarcinoma.” One case of abdominal obstruction caused by left colon cancer was postoperatively diagnosed as “adenocarcinoma.” The above 4 cases of abdominal obstruction due to colon pain. In patients, their cancer cells have penetrated the intestinal wall. Peripheral mesenteric lymph nodes were swollen to varying degrees. The pathological stage is “Dukes C_1” period. During the operation, 3 cases of right hemicolary and colorectal cancer patients were treated with first-ever resection of the pain and then the right colon and associated mesentery were removed. Intestinal ileum and colon end-stage anastomosis were performed in one intestine, and one patient with abdominal obstruction caused by left colon cancer underwent emergency resection of the cancer and its own mesorectum. The distal segment of the colon was closed and sutured and closed. , The proximal segment of the left abdomen wall has external ostium. Colon cancer is one of the most common visceral malignancies, and it has other clinical manifestations such as nasopharyngeal carcinoma, esophageal cancer, breast cancer, and cervical cancer. Variety of characteristics, often difficult to prevent in many aspects of treatment, colon cancer and abdominal obstruction are often accidentally found in the emergency exploratory laparotomy surgery, while the implementation of simultaneous colon cancer emergency one-time removal and colon first-phase anastomosis, first must pay attention to the abdominal cavity, surgery The establishment of a wild clean surgical environment, avoiding unnecessary blind crushing of tumors, preventing the spread of cancer cells through the blood tract, metastasis and abdominal cavity, parietal peritoneum, surgical mucous membrane, tissue cultivation,
