本病为一原因不明的难治性疾病,多数先于内科治疗,仅少数适于外科治疗。其手术适应症为保守疗法无效的急症型、病变明显而症状不见缓解的全结肠型者为主要对象。日本一度曾扩大了手术范围,但随着经验的积累,又将适应症进而严格化,虽然病例在增加,但施行手术的比率在下降,同时对局部性病变及全身损害明显者则主要转向手术,因而在外科治疗上发现了一些问题。 The disease is a refractory disease of unknown cause, most precede medical treatment, only a few suitable for surgical treatment. The surgical indications for the conservative treatment ineffective emergency type, the lesion was obvious and the symptoms did not ease the whole colon type as the main target. Japan once expanded the scope of the operation, but with the accumulation of experience, and then the indications and then strict, although the cases are increasing, but the rate of operation is declining, while the local lesions and systemic injury were mainly turned to surgery , And therefore found some problems in surgical treatment.
