克罗恩病并发肠瘘的诊断与治疗

目的探讨克罗恩病(CD)并发肠瘘的诊断与治疗方法。方法对1978至2004年收治的62例CD并发肠瘘患者的临床资料进行分析。结果本组肠外瘘68例次,其中多发瘘6例次;肠内瘘8例次。肠瘘以末端回肠瘘(27例次)和回结肠吻合口瘘(21例次)为主。手术方式主要为回结肠吻合口拆除重建(26例次)和回盲部切除回结肠吻合(14例次)。首次肠瘘、术后服用免疫药物者复发率15.4%,明显低于未服药患者(34.8%);复发时间为(40±17)个月,明显长于不服药组的(8±3)个月;两组比较,P<0.01。结论CD合并的肠瘘以肠外瘘为主。主要手术方法为瘘口切除与肠吻合术。术后应用免疫抑制药物可降低CD合并肠瘘的复发率。

Diagnosis and management of Crohn disease complicated with gastrointestinal fistulae

OBJECTIVE: To investigate the diagnosis and treatment of patients with Crohn disease (CD) complicated with gastrointestinal fistulae. METHODS: Clinical data of sixty-two cases with CD complicated with gastrointestinal fistula e from 1978 to 2004 were analyzed. RESULTS: These were 68 external fistulae in 6 2 patients including recurrent fistulae in 6 cases, internal fistulae in 8 cases . Twenty- seven fistulae were located in the terminal ileum and 21 fistulae wer e located in ileocolic anastomosis site. The main surgery included 14 ileocecal resections with primary anastomosis and 26 resections of original ileocolic anastomosis with fistula and re-anastomosis. The incidence of recurrence was lower (15.4% ) in patients with postoperative medication including sulfasalazine and immunomodulator than that (34.8% ) in patients without postoperative immunomodulator,but the recurrence time was longer (40+/- 17) months] in patients with postoperative medication than that (8+/- 3)months] in the patients without postoperative specific medication. CONCLUSIONS: Most CD fistulae are external fistulae,most of the external fistulae are treated by resection of the fistula and anostomosis. Specific medication including sulfasalazine,mesalamine and immunomodulators should be used to prevent postoperative complications and CD recurrence.
