摘　　要：目的 探讨螺旋CT对直肠癌术后复发的诊断价值。方法 采用螺旋CT结合三维重建,对48例直肠癌术后复发的患者进行检查。结果 48例患者中,37例局部复发的CT表现为吻合口区肠壁不规则结节状、新月状软组织密度影,向腔内或肌层生长;其中16例伴侵犯邻近组织器官,(6例侵犯膀胱、前列腺、一侧或两侧精囊腺,3例侵犯子宫、阴道,7例侵犯骶骨及骶骨前软组织、直肠浆膜外脂肪层)。19例为远处转移(伴局部复发8例),多见于肝脏。结论 螺旋CT扫描结合三维重建,对诊断直肠癌术后复发具有重要的临床应用价值。Objective To explore the clinical value of spiral CT scan in diagnosing the postoperative recurrence of rectal carcinoma.Methods Forty-eight patients with the postoperative recurrence of rectal carcinoma were scanned by spiral CT with 3D reconstruction. Results Thirty-seven cases with the anastomotic stoma in 48 cases recurred after surgery and the main CT findings of the recurrence of the rectal carcinoma were as follows: irregular soft tissue or nodule at anastomotic stoma; mass around the anastomotic stoma or in front of the sacral bone; Sixteen cases were shown with the tumor involvement of the adjacent organs in CT scan. Nineteen cases with metastasis were seen and the liver was the common site of metastasis. Conclusion Spiral CT scan combined with 3D reconstruction has the significant value in diagnosing the postoperative recurrence of rectal carcinoma in clinic.
