慢性放射性肠损伤的外科治疗

目的 探讨慢性放射性肠损伤( CRII)外科治疗的方法及临床效果.方法 回顾性总结2001年1月至2010年12月南京军区南京总医院外科连续治疗的206例CRII患者资料.其中男64例,女142例,年龄(50±11)岁.总结手术原因、手术方式、手术并发症及病死率.结果 206例CRII患者手术治疗229次,其中手术≥2次者31例.手术原因为肠梗阻142例次、肠瘘56例次、直肠炎12例次、出血6例次及其他手术13例次.229例次手术包括:病变肠切除+Ⅰ期肠吻合术142例,病变肠切除+肠造口术57例,病变肠袢旷置术14例,其他手术16例.术后肠道相关并发症53例(25.7％),术后28 d内病死率2.4％( 5/206).结论 合并肠梗阻、瘘、出血、穿孔等并发症的CRII需要外科治疗,选择合适的患者可以成功地实施病变肠切除Ⅰ期吻合,合理地应用肠造口术能够降低并发症及病死率.

Outcomes of chronic radiation intestinal injury treated with surgical interventions

Objective To explore the surgical approaches and clinical outcomes of chronic radiation intestinal injury ( CRII ).Methods From January 1,2001 to December 31,2010,at Department of Surgery,Nanjing General Hospital of Nanjing Command a consecutive series of 206 CRII patients undergoing surgical interventions was reviewed retrospectively.There were 64 males and 142 females with an age range of (50 ± 11 ) years old.The indications,surgical approaches,surgical complications and mortality were analyzed.Results 206 CRII patients received 229 surgical treatment,31 patients underwent two or more operations.The course of surgical interventions included intestinal obstruction ( n =142 ),intestinal fistula (n=56),proctitis (n =12),bleeding (n =6) and others (n =13).They underwent 229 laparotomies including intestinal resection and primary anastomosis (n =142),intestinal resection and enterostomy (n =57),exclusion of radiation-related gastrointestinal diseases ( n =14 ) and other procedures ( n =16).The occurrence rate of postoperative intestinal complications was 25.7％ ( 53/206 ).Five patients ( 2.4％ ) died within the postoperative 28 days.Conclusion Surgery is often required for patients with chronic radiationinduced intestinal obstruction,fistula,hemorrhage and perforation,etc.Resection and primary anastomosis with undamaged segments may be performed safely in selected patients.And a judicious use of stoma can reduce the rates of major surgical mortality and morbidity.
