Abstract:
Objective To investigate the curative effects of partial internal sphincterotomy in the posterior midline and lateral position in treatment of chronic anal fissure. Methods One hundred and fifty cases chronic anal fissure patients with stageⅡ or Ⅲ were randomly divided into observation group(80 cases)and control group(70 cases),who were hospitalized in the Shunyi District Hospital of Beijing from Dec. 2009 to Oct. 2012. The patients of two group were treatment by internal sphincterotomy either in the posterior midline or lateral position respectively. The efficacy,healing time,complications and recurrence of the two groups were recorded and compared. Results There were 76 cases with cure,6 cases with improvement and 2 with ineffective effect in the observer group. There were 49 cases with cure,12 cased with improvement and 9 cases with ineffective effect in control group. The difference of the efficacy was statistically significant( P =0. 025). Wound healing time of observation group and control group were(9. 9 ± 0. 8)d and(17. 1 ± 0. 9)d,and the difference was significant( P =0. 048 ). The incidence of anal exudates in observer group was lower than the control group(2. 5%(2/80)vs. 24. 3%(17/70);P=0. 032). The incidence of recurrence in observer group was 5. 0%(4/80),lower than the control group(24. 3%(17/70),P=0. 046). The degree of the postoperative pain,voiding dysfunction and wound edema in observer group were lower than the other group( P =0. 025, 0. 025,0. 049). Conclusion The effect of internal sphincterotomy in the lateral position in treatment of chronic anal fissure is better with quickly repair,fewer complications.
