多发性大肠癌已有较多报道。我们遇到一例异时多发性大肠癌合并结肠梗阻,因缺乏认识导致术中误诊,教训深刻,现报道如下: 患者男性,46岁,曾因便血和大便习惯改变,于1972年在中山医学院肿瘤医院诊断为直肠上段癌,经腹行保留肛门乙状结肠直肠切除术。三个月后因绞窄性粘连性肠梗阻,在我院行小肠部分切除术治愈。1983年3月起有上腹部隐痛,11月起先后4次发生腹部阵发性绞痛和腹胀,11月24日腹痛加剧,诊断为粘连性肠梗 Multiple colorectal cancer has been reported. We encountered a case of multiple colorectal cancer complicated with colonic obstruction. The lack of knowledge led to misdiagnosis during surgery. The lesson is as follows: The patient was a 46-year-old male patient who had suffered from changes in bloody stool and bowel habits at Zhongshan Medical College in 1972. The tumor hospital diagnosed with upper rectal cancer and reserved anal sigmoid colorectal resection. Three months later, due to strangulated adhesion obstruction, a partial small bowel resection was performed in our hospital. Since March 1983, there has been pain in the upper abdomen. From November onwards, there have been 4 consecutive episodes of abdominal paroxysmal cramps and bloating. On November 24th, abdominal pain has intensified. The diagnosis of adhesive intestinal stalks has been made.
