Objective: Postoperative small bowel obstruction is one of the adverse effects of appendectomy but its frequency varies from center to other. This study was conducted to determine the incidence of this complication among our patients who had appendectomy and identify the factors which may increase the risk. Methods: Patients readmitted for adhesive small bowel obstruction were traced and their clinical data were analyzed. Results: Six hundred and seven patients were el for the study. Six patients (1%) developed in the obstruction. Frequency of readmission of patients features of intestinal obstruction ranged from 1-6 (of 2 times). Conclusion: The incidence of small bowel after appendectomy is low. The main risk factors reviewed and measures to avoid them were suggested.
