Background: Haemorrhoidal disease is likely one of the earliest illnesses known to man, maybe dating back to the time when he first stood upright1. It causes considerable pain, suffering, and a decline in quality of life. Haemorrhoids are common vascular cushions within the canal. [1.2] The term haemorrhoids is derived from the Greek word haimorrhoos, which means bleeding, and the word pile is derived from the Latin word Pila, which means a pill or a ball, thus showing two cardinal symptoms: bleeding and prolapse of mass per rectum. Aim’s & Objectives: To evaluate the effectiveness of Metronidazole in giving relief from pain in all patients undergoing closed haemorrhoidectomy and to evaluate the requirement of analgesic use in relieving the pain, post closed haemorrhoidectomy . Methods & Materials: The proposed study will be conducted on patients attending General Surgery OPD with chief complaint of Haemorrhoids from May 2012 to March 2014. There were 60 patients undergoing closed haemorrhoidectomy Results: The mean VAS-Score of the pain in the group-A on the day 0 was 9.5 and in the group-B was 9.7 . On the day 7 the mean VAS-Score of the pain in the group-A on day 0 was 0.53 and in the group-B was 2.07 . The mean VAS-Score of the pain in the group-A on all the seven days was significantly lower than the VAS-Score of the group-B. The p<0.05 means significant; in all the days the p value is significant. Conclusion: In the metronidazole group, there were no problems, whereas in the nonmetronidazole group, three patients experienced fever and two had discharge from the surgical site. We observed that all patients with problems had haemorrhoids of grade . Thus, there is a higher rate of problems in the non-metronidazole group when the size of the wound is considerable. Metronidazole should be administered consistently to hemorrhoidectomy patients, according to the findings of the current study
