Results CT scan indicated that cancer relapsed 3 to 84 months after surgery.For patients with colostomy,the CT scan showed nodular or lobulated mass in the areas of perineum and presacralis,as well as loss of presacral fat space.For patients without colostomy.CT finding included thickened rectal wall with unregular proximal tumor,rectal obliteration,rectostenosis and ddisplacement of perirectal fat space.

结果 肿瘤复发的CT表现：造瘘术后CT表现为会阴及骶前区肿块，呈结节状或分叶状，骶前脂肪间隙消失；无造瘘术后CT表现新直肠壁增厚伴不规则偏心性肿块，管腔狭窄及闭塞，直肠周围脂肪间隙狭窄移位。

The causes of failure in the pre-experimental stage were anesthesia accidents, thrombosis of the arterial anastomosis, massive hemorrhage, air embol ism and phlebemphraxis.

结果 共进行大鼠异位肾移植术104 次，其中预实验阶段62 次，成功50 次（80.6%），失败12 次，主要原因为麻醉意外、动脉吻合口血栓和大出血、静脉空气栓塞、静脉闭塞等；正式实验42 次，成功40 次（95.2%），失败2 次，分别为迟发性动脉吻合口出血和吻合口血栓引起。

Cases of superior mesenteric venous thrombosis were found, in one case, the SMV was occlusion completely. MSCTA showed the SMV and portal venous unopacification, in the other case, the filling defect was seen in SMV in portal venous, and the strip low density was seen in MSCTA.. The other signs of AMI included bowel wall edema and thickening、massive fluid in the bowel and ascites in all 5 cases, mesenteric edema and pneumatosis in 2 cases respectively.

肠系膜上静脉梗塞2例，其中1例SMV完全闭塞，管腔内无对比剂充盈，MSCTA示SMV和门静脉均未显影；另1例SMV内见充盈缺损影，MSCTA示SMV内见条状低密度影。。5例均见小肠病变肠管壁明显增厚、肿胀，肠管积液扩张及腹水，2例见肠系膜水肿，2例并肠壁积气。

Lung transplantation is the only effective treatment for final stage pneumonopathy.

肺移植是目前治疗终末期肺病的惟一有效方法，而闭塞性支气管炎是阻止肺移植长期存活的最主要并发症，其中支气管上皮细胞是引起这种迟发性排斥反应的主要靶器官。
