特发性大肠破裂是少见的疾病之一。系指排除外伤、癌肿、憩室等引起的大肠破裂。诊断要点是:①肠管穿孔部位没有肉眼可见病变,②肠管内无异物及通过障碍,③腹腔内无粘连无腹内外疝,④无外伤或医源性肠管损伤。最近有人将切除的标本做组织学检查发现肉眼诊断的特发性大肠破裂不少是憩室穿孔。乾秀等强调,为了证实临床诊断,切除标本必须进行组织学检查,其特点是:①粘膜在穿孔边缘中断、未潜入浆膜, Idiopathic large intestine rupture is one of the rare diseases. It refers to the elimination of large intestine rupture caused by trauma, cancer, and diverticulum. The diagnostic points are: 1 There is no visible lesion in the perforation site of the intestine, 2 there is no foreign body in the intestinal canal, and no obstruction occurs, 3 there is no adhesion in the abdominal cavity, no abdominal and external hemorrhoids, 4 no trauma or iatrogenic bowel injury. Recently, a histological examination of a resected specimen revealed that a large number of idiopathic large intestine ruptures diagnosed by the naked eye were perforation of the diverticulum. Gan Xiu, etc. emphasized that in order to confirm clinical diagnosis, resection specimens must undergo histological examination, which is characterized by: (1) The mucosa is interrupted at the edge of the perforation, and no sneak into the serosa.
