回盲部包括回肠末段、盲肠及阑尾、升结肠始段等部份,均属回结肠动脉供血区。该部淋巴组织丰富,粪便保持稀糊状,因此回盲部疾病有其特征性。回肠末段与盲肠、升结肠始段虽然结构与功能不同,且有回盲瓣相隔,却常罹患相同疾病,也可同时受累。由于盲肠、升结肠肠腔宽阔,稀糊粪便对病灶刺激微弱,故病的初期可无症状或仅有轻微不适,易为病者所忽视。另外,回盲部病变如未侵及浆膜,其腹
Ileocecal, including the distal ileum, cecum and appendix, the beginning of the colon and other parts of the colon, are back to the colonic artery blood supply area. The Department of lymphoid tissue rich, stool to keep thin paste, so the disease of the ileocecal has its own characteristics.

In addition, ileocecal lesions such as invasion of the serosa, the abdomen
