The Difference between Conventional Lateral Internal Sphincterotomy vs One Step Controlled Sphincterotomy as a Treatment for Chronic Anal Fissure

ABSTRACT

Objective: In this study our main goal is to evaluate thedifference between conventional lateral internal sphincterotomyvs one step controlled sphincterotomy as a treatment forchronic anal fissure.Method: This quasi experimental study was carried out atdifferent Private Hospital, in Dhaka City from November 2008to October 2010 where 85 patients were included in this study.Grouping was done non randomly. Informed consent wasobtained from all patients after explanation of the nature of analfissure and possible treatment.Result: During the study, bleeding per rectum was found in 35(77.8%) in Group A (conventional group) and 30 (75.0%) inGroup B (one step controlled group).In Group A (conventionalgroup) pain was relived in mean 5.0(SD 3.8) (range 2-14) daysand in Group B (one step controlled group) pain was relived inmean 1.9(SD 1.2) (range 1-7) days. Which was statisticallysignificant (p<0.05).Conclusion: From our results; we can conclude that, one stepcontrolled lateral internal sphincterotomy is comparativelybetter than conventional technique which serves much moreconvenient treatment for chronic anal fissure. Further study isneeded for better outcome.
