Hemorrhoids are the cushions of sub mucosal tissue with venules, arterioles and smooth muscle fibers that are located in anal canal. Anal bleeding and mass per-rectum are common presenting symptoms. Hemorrhoidectomy is a frequently performed surgical procedure and associated with post-procedural pain. In the present study attempt has been made to compare the Conventional Open Hemorrhoidectomy with the new modality of Ligasure Hemorrhoidectomy in the treatment of Grade III and IV Hemorrhoids, thereby, trying to highlight the advantages and disadvantages if this new method. A randomized prospective study of 60 patients was conducted, study included patient of all age groups and both sexes. Study showed significant difference (P<0.001) in Ligasure group with respect to intra-operative blood loss, time taken for surgery, duration of hospital stay. Ligasure group patient experienced significantly(P<0.001) less pain than the Conventional group even at two weeks also return to work was earlier in Ligasure group. In the follow up, there was no major complication due to the use of Ligasure for hemorrhoidectomy with excellent patient acceptance and satisfaction. Technically the Ligasure method is much simpler and can be safely and effectively carried out by surgeons.
