目的：探讨改良Swellson手术治疗先天性巨结肠的有效性、安全性。方法：分析我院自1998年4月～2006年5月采用改良Swenson术治疗的36例(男性26例、女性10例,28例为常见型,4例为短型,4例为全结肠型)先天性巨肠患儿进行回顾性分析,所有患儿均经病理明确诊断,术后随访行肛门指检,6月时行钡灌肠复查。随访20例,时间6月—8年,对顽固性便秘,营养状况,吻合口狭窄,污裤及失禁等情况进行评价。结果：36例患儿顽固性便秘消失34例。2例仍存在不同程度便秘。近期均无吻合口漏。无腹腔及切口感染。远期随访的20例患儿有2例再发便秘,2例有污粪现象,小肠结肠炎2例。结论：改良Swenson术适用于短段型、常见型、长段型、先天性巨结肠,疗效满意,但对全结肠型治疗尚待进一步研究。 Objective: To investigate the effectiveness and safety of modified Swellson surgery for Hirschsprung’s disease. Methods: Thirty-six patients (26 males, 10 females, 28 were common type, 4 were short type and 4 were type of colon type) were treated in our hospital from April 1998 to May 2006 A retrospective analysis of children with congenital giant intestine, all children were diagnosed by pathology, postoperative follow-up anus finger examination, barium enema in June to review. Follow-up of 20 cases, time from June to 8 years, refractory constipation, nutritional status, anastomotic stenosis, pant and incontinence, etc. were evaluated. Results: 36 cases of refractory constipation disappeared in 34 cases. 2 cases still exist in varying degrees of constipation. No recent anastomotic leakage. No abdominal and incision infection. Long-term follow-up of 20 cases of children with recurrent constipation, 2 cases of sewage manure, 2 cases of enterocolitis. Conclusion: The modified Swenson technique is suitable for short segment type, common type, long segment type and Hirschsprung ’s disease. The curative effect is satisfactory. However, further studies on the treatment of colon type are needed.
