We report a case of spontaneous rupture of the rectosigmoid junction demonstrated by surgical and histological examination. This rare complication of chronic constipation is difficult to confirm except in the case of the typical clinical presentation with lower abdominal pain after defaecation and evisceration of small intestine loops through the anus. No radiological procedure is usually performed except for plain abdominal radiograph, to demonstrate inconstant (retro)peritoneal emphysema. CT scan could detect free air outside of the rectosigmoid lumen, suggesting parietal rupture and allowing appropriate surgical treatment on the lower digestive tract.
我们报告一例经手术和组织学检查证实的直肠乙状结肠交界处自发性破裂病例。这种慢性便秘的罕见并发症很难确诊，除非出现典型的临床表现，即排便后下腹痛以及小肠袢经肛门脱出。除了腹部平片外，通常不进行其他放射学检查，以显示不恒定的（腹膜后）皮下气肿。CT扫描可以检测到直肠乙状结肠腔外的游离气体，提示肠壁破裂，从而能够对下消化道进行适当的手术治疗。
