摘　　要：目的探讨小肠最小化切除策略对预防慢性放射性肠损伤(CRE)术后吻合口漏和短肠综合征等并发症的效果。方法采用回顾性队列研究方法。合并肠狭窄和肠梗阻的小肠CRE可分为以下两种分型:(1)Ⅰ型:回肠末端病变,但在回肠病变与回盲部之间始终存在2~20 cm的正常回肠段;(2)Ⅱ型:病灶位于距离回盲部较远的小肠,病灶外的肠段通常广泛受损。最小化肠切除术适应证:Ⅰ型小肠CRE、直肠乙状结肠无放射性损伤、无结肠梗阻。禁忌证包括各种原因导致的盲肠远端狭窄性或穿透性病变、急诊手术、恶性肿瘤复发或复发性恶性肿瘤的放疗史、放疗与手术时间间隔<6个月、术前小肠切除史或腹腔化疗史。根据上述指征,回顾性分析2017年4月至2019年12月期间,接受最小化肠切除术策略治疗的40例Ⅰ型CRE患者病例资料(最小化肠切除组,其中东部战区总医院13例,上海交通大学医学院附属第九人民医院16例,徐州医科大学附属医院11例);同时纳入2015年10月至2017年3月期间,40例接受切除肠狭窄病变及回盲部的Ⅰ型CRE患者作为历史对照(传统肠切除组,均来自东部战区总医院)。最小化肠切除组采用小肠最小化切除策略,即一期回肠部分切除+回肠-回肠吻合术+保护性小肠造口术。传统肠切除组采用回盲部切除+回肠升结肠吻合术。观察两组手术情况、术后并发症的发生情况、术后恢复情况和手术前后生活质量变化。术后并发症严重程度采用Clavien-Dindo和综合并发症指数(CCI)评估。采用卡氏评分(KPS)对两组患者术前和术后的生活质量进行评价,得分越高,表示生活质量越好。结果两组基线资料比较,差异无统计学意义(均P>0.05)。与传统肠切除组相比,最小化肠切除组的小肠切除长度[51(20~200)cm比91(60~200)cm,Z=5.653,P<0.001]、术后全肠内营养时间[9(3~18)d比12(4~50)d,Z=2.172,P=0.030]和术后住院时间[17(9~24)Objective To investigate the efficacy of strategies for minimizing small bowel resection during surgery for pelvic radiation-induced terminal small intestinal stenosis in preventing postoperative complications such as anastomotic leakage and short bowel syndrome.Methods This was a retrospective cohort study.There are two subtypes of chronic radiation enteritis(CRE)with combined intestinal stenosis and intestinal obstruction:(1)Type I:terminal ileal lesions with a normal ileal segment of 2–20 cm between the ileal lesion and ileocecal junction;and(2)Type II:the lesion is located in the small bowel at a distance from the ileocecal region,usually accompanied by extensive damage to the bowel segments outside the lesion.The indications for minimal bowel resection are as follows:(1)diagnosis of Type I small bowel CRE;(2)absence of radiological evidence of rectosigmoid damage;and(3)absence of colonic obstruction.The contraindications are:(1)stenotic,penetrating lesions of the distal cecum;(2)emergency surgery;(3)recurrence of malignant tumor or history of radiotherapy for recurrent malignant tumor;(4)interval between radiotherapy and surgery<6 months;and(5)history of preoperative small bowel resection or abdominal chemotherapy.Case data of 40 patients with Type I CRE who met the above criteria and had undergone minimal bowel resection between April 2017 and December 2019 were retrospectively analyzed(minimal bowel resection group;including 13 patients from Jinling Hospital,16 from the Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine,and 11 from the Affiliated Hospital of Xuzhou Medical University).Forty patients with Type I CRE who had undergone resection of intestinal stenosis lesions and the ileocecal region between October 2015 and March 2017 were included as historical controls(conventional resection group;all from Jinling Hospital).The specific strategy for minimal bowel resection was one-stage partial ileal resection+ileo anastomosis+protective small bowel stoma.In contrast,c
