By studying the morbidity of surgery conducted by surgery physicians’ surgery ward at Rasool Akram hospital, we wanted to reduce morbidity cause and take a little step in improving the patient's health. Method: Medical records of patients operated in rasool akram hospital was investigated and information such as surgery, intraoperative and postoperative complication associated v variables were recorded in the check list. Result: Re-laparotomy possibility in Men was 3.5 times more than women Metastatic pathology likely increases the necessity of re-laparotomy to 1.2. The possibility of re-laparotomy in a patient who has a history of positive chemotherapy increase up to 2.9. The possibility of re-laparotomy in case of prolapse increases to 2.4 (1.8-3). Conclusion: The possibility of re-laparotomy increases with factors such as male gender, metastatic pathology, positive history of chemotherapy, the incidence of prolapse and incidence of adhesion. Although having Gl anastomosis increases the risks of post op complications and being problem with the colostomy leading to its closure are such important issues in predicting relaparotomy chances.
