Mesenteric vascular occlusion is a lethal condition resulting from critically reduced perfusion to the GIT. It accounts for 1-2% of admissions for abdominal pain. Though rare, this disease has been found to be quite fatal with the average mortality rate of this disease being around 70%. This study was hence done to find out the incidence of this disease among people who have been admitted with complaints of abdominal pain. To study the incidence of mesenteric vascular occlusion in patients presenting to the hospital. To study the case files of patients admitted with abdominal pain and check the incidence of mesenteric vascular occlusion among them. Research was conducted in a private medical college in South India for over a period of 5 months, from March 2020 to August 2020. The sampling frame comprised of patients who have been admitted to the Department of General Surgery with complaints of abdominal pain. The sample size taken was 500. Details of the patients such as name, age, gender and their chief complaints were obtained through analysis of case sheets and in-patient case files. Ethical clearance was obtained from the Institutional Ethics Committee of Saveetha Medical College and Hospital, Chennai, India. The collected data was entered in Microsoft Ex- cel 2013 and statistical analysis was carried out. The cause of abdominal pain due to the incidence of mesenteric vascular occlu- sion was found to be prevalent among 16 of the total number of patient files assessed. The incidence of mesenteric vascular occlusion in our hospital was found to be 3.2% of the total patients admitted due to abdominal pain between the above mentioned periods.
