OBJECTIVE: This study was designed to compare short term outcome of post operative pain in
patients operated for haemorrhoidectomy alone and haemorrhoidectomy with internal sphincterotomy.
METHODOLOGY: This comparative observational study conducted at Liaquat University Hospital
Jamshoro during August 2012 to July 2014. One hundred and sixteen patients of 3rd or 4th
degree hemorrhoids were enrolled in the study. Patients were divided into two comparable
groups. Group A underwent open haemorrhoidectomy along with lateral sphincterotomy
whereas group B was operated for open haemorrhoidectomy alone. Postoperative pain was
analyzed by using visual analogue score at 24 hours, 48 hours and on 10th post operative day.
RESULTS: Total 116 patients were included in the study. Fifty eight patients in each group. The
mean age of the patients was 42± 10.2. Male were 77 (66.4%) and 39 (33.6%) were female. Male
to female ration was 2:1. During follow-up periods, patient in group A experienced less postoperative
pain as compared to group B (p value is â‰¤ 0.05) . None of the patient developed flatus or
CONCLUSION: Lateral internal sphincterotomy combined with haemorrhoidectomy significantly
reduces postoperative pain without increasing morbidity.
