目的评价乙状结肠成形在超低位直肠吻合术中的临床应用价值。方法对比乙状结肠成形超低位直肠吻合术(观察组,35例)和乙状结肠-直肠超低位吻合术(对照组,33例)两组患者术后并发症发生率及肛门功能恢复情况。结果观察组手术并发症发生率17.1%,对照组21.2%;两组差异无统计学意义(P>0.05)。术后12个月,观察组患者每日大便1～5.5次(平均2次/d),对照组1～9次(平均3.5次/d),两组差异有统计学意义(P<0.01);在大便控制方面观察组明显优于对照组(P<0.01);患者的自我满意程度观察组高于对照组,P<0.01;术后肛门功能得分观察组2.57分,对照组7.21分,两组比较,P<0.01。结论乙状结肠成形应用在超低位直肠吻合术中,不增加手术并发症,术后肛门功能恢复明显优于结肠直肠直接吻合术。
Objective To evaluate the clinical value of sigmoid colon formation in ultra-low rectal anastomosis. Methods The incidence of postoperative complications and the recovery of anus were compared between two groups of patients undergoing sigmoid colon ultra-low rectal anastomosis (observation group, 35 cases) and sigmoid-rectal ultra-low anastomosis (control group, 33 cases). Results The incidence of complications was 17.1% in the observation group and 21.2% in the control group. There was no significant difference between the two groups (P> 0.05). At 12 months after operation, the patients in the observation group had a daily stool of 1 ~ 5.5 times (average 2 times / d) and control group of 1 ~ 9 times (average 3.5 times / d), the difference between the two groups was statistically significant (P0.01) (P <0.01). The degree of self-satisfaction in the observation group was higher than that in the control group (P <0.01), the anal function score was 2.57 in the observation group and 7.21 in the control group Group comparison, P <0.01. Conclusions The application of sigmoid colon in ultra-low rectal anastomosis does not increase the complication of operation. The postoperative anal function recovery is obviously better than that of colorectal direct anastomosis.
