结肠次全切除、逆蠕动盲肠直肠吻合术与结肠全切除、回肠直肠吻合术治疗慢传输型便秘的对比研究

目的 比较结肠次全切除、逆蠕动盲肠直肠吻合术和结肠全切除、回肠直肠吻合术治疗重度慢传输型便秘的疗效.方法 回顾性分析1999年1月至2008年6月52例慢传输型便秘患者的临床资料.其中32例行结肠次全切除、逆蠕动盲肠直肠吻合术,20例接受结肠全切除、回肠直肠吻合术.统计分析两组临床疗效并进行平行对比.结果 术后患者随访1～7年(中位时间4年).两组患者一般资料具有可比性.中位随访4年,结肠次全切除组每日大便次数显著低于结肠全切除组(2.5±0.8比3.4±0.8;P=0.000).Wexner肛门失禁评分结肠全切除组高于结肠次全切除组(5.8±1.9比4.4±1.6;P=0.011).胃肠生活质量评分结肠次全切除组显著高于结肠全切除组(120.7±7.5比111.1±12.0;P=0.005).结论 与结肠全切除术相比,对于慢传输便秘患者,行结肠次全切除、逆蠕动盲肠直肠吻合术后可获得更好的疗效和生活质量.

Comparison of subtotal colectomy with antiperistaltic cecoproctostomy and total cotectomy with ileoproctostomy in treating slow transit constipation

Objective To compare clinical outcome and quality of life of subtotal colectomy with antiperistaltic cecoproctostomy and total colectomy with ileorectal anastomosis (TAC-IRA) in patients with severe slow transit constipation (STC). Methods Of the 56 patients enrolled in this study from January 1999 to June 2008, 32 cases underwent subtotal colectomy with antiperistaltic cecoproctostomy, and 20 patients underwent TAC-IRA. The patients' clinical characteristics, operative data, postoperative outcome, functional result and gastrointestinal quality of life index ( CIQLI) survey were compared between the two groups. Results All patients were followed up for 1-7 years ( median, 4 years). The basic clinical characteristics between the two groups was comparable. During the follow-up period, the number of daily bowel movements in the subtotal colectomy group was significantly fewer than that in TAC-IRA group(2. 5 ± 0. 8 vs. 3. 4 ±0. 8; P =0.000). The Wexner continence score was significantly lower in subtotal colectomy group (4.4 ± 1. 6 vs. 5. 8 ±1.9; P = 0.011), and the GIQLI score in subtotal colectomy group was significantly higher than that in the TAC-IRA group (120.7 ±7.5 vs. 111. 1 ±12.0; P = 0.005). Conclusion Subtotal colectomy with antiperistaltic cecoproctostomy appeared to be the superior treatment than the TAC-IRA for selected patients with slow transit constipation for improved functional outcomes and quality of life.
