Infection at the surgical site, which leads to the development of excessive tension causing inadequate healing is the most common cause of incisional hernia. Objective: To find out risk factors associated with incisional hernia and its prevalence. Method: A general proforma was prepared for studying each case in detail and underwent routine blood, radiology investigations. A detailed enquiry was made regarding the demographic profile, history of previous operations, its nature and postoperative period. Onset and progress of the hernia were noted. Result: During the study period total operated cases were 921. From that 50 cases of incisional were reported during the follow-up. Out of fifty cases 12 (24%) were male, and 38 (76%) were female. Ratio of male to female is 1:3.2. The difference was found to be significant (p<0.05). Maximum cases were distributed between the age group of 41-50 (32%). Overall highest prevalence of incisional hernia was noted with perforation peritonitis operation, and female it was noted with LSCS operation commonest incision was midline (76 %) which lead to incisional hernia. Conclusion: The prevalence rate of incisional hernia was 5.42%. Overall highest prevalence of incisional hernia was noted with perforation peritonitis operation, and female it was noted with LSCS operation. 76 % cases of incisional hernia associated with midline incision.
