作者随访了250例直肠癌经腹会阴切除术患者,64例(25.6%)在术中穿破直肠。通过与未穿破直肠的病例相比较,分析这一医源性直肠穿破与其预防的关系。分析表明穿破本身并不影响 Dukes A 或 D 级肿瘤患者的长期结果,但增加 Dukes B 和 C 级肿瘤患者的复发率(57%∶34%),也降低了患者的5年存 The authors followed 250 cases of rectal cancer with transabdominal perineal resection, and 64 cases (25.6%) broke through the rectum during operation. The relationship between this iatrogenic perforation and its prevention was analyzed by comparison with the case of unbroken rectum. Analysis showed that wearout did not affect the long-term outcome of patients with Dukes A or D tumors, but increased the recurrence rate of Dukes B and C tumor patients (57%: 34%), also reduced the patient’s 5-year survival
