摘要
目的探讨改良后位内括约肌部分切断术加指法扩肛的优越性。方法本院收治肛裂病例200例，随机分组，治疗组和对照组各100例。治疗组采用改良后切法：于肛裂后正中偏右15°切开部分内括约肌（上下纵高0．5～0．9cm，内外横厚约0．4cm），配以手法扩肛。对照组采用传统后切法：于肛裂后正中切开内括约肌（上至齿线上0．3cm）作整体切断，开放创口。结果治疗组疼痛缓解时间为（1．2±0．4）d，而对照组为（2．4±0．6）d；治疗组复发为0例，而对照组为4例；治疗组溃疡愈合时间为（11．5±1．5）d，而对照组为（16．5±2．5）d；治疗组肛门控制功能障碍为0例，而对照组为6例；治疗组治愈率为100％，而对照组为86％。结论改良后切加扩肛术明显优于传统后切术，具有术中出血少，术后肛门疼痛轻，感染机会少，疗程短，治愈率高，无肛门控制功能障碍，愈后复发率极低等优点。另外，此法操作简便，便于临床应用。
Objective To investigate the modified posterior internal sphincter resection combined with anal sphincter extension for chronic anal fissure. Method Of anal fissure patients were treated in our hospital, 200 cases were randomly assigned to treatment group and control group of 100 cases. Treatment group improved cutting method ： After the center - right and anal fissure cut the part of the sphincter 15 ° （ vertical up and down the high 0.5 -0.9cm, inside and outside the horizontal thickness 0. 4cm）. Together with the fingers extended up to four fingers anal. After cutting the control group using the traditional method ： the posterior midline incision in anal sphincter （ up to the teeth online 0. 5 cm） debridement and drainage as a whole cut. Results Of pain relief time was 1.2 ± 0.4, while the control group was 2. 4 ± 0. 6 ; treatment group the recurrence rate was 0, while the control group 4 ; treatment group ulcer healing time was 11. 5 ± 1.5, while the control group was 16. 5 ± 2. 5 ; anal control dysfunction treatment group to 0, while the control group was 6; treatment group was 100% in cure rate, while the control group was 86%. Conclusion The modified posterior internal sphincter resection combined with anal dilation for chronic anal fissure is better than conventional surgery, with less bleeding, anal pain, less chances of infection, short course, high cure rate, no anal control dysfunction, the low recurrence rate. In addition, this method is simple and easy for clinical application.
