Acute appendicitis has been proven to be a usual cause of mechanical small bowel obstruction since 1901, but there has been very little specific research on this subject. It usually occurs as an effect of adhesion because of periappendicular inflammation. Although previous studies exist, this presentation of acute appendicitis is not widely identified, which might lead to delays in making the right diagnosis and initiating treatment. We herein report a 17-year-old male patient who presented with the clinical manifestations of intestinal obstruction and fever for 3 days. Preoperative ultrasound and subsequent computed tomography were performed. On laparotomy, an obstructed bowel was seen, and the appendix was recognized to be the cause. We herein report a case of intestinal obstruction due to acute appendicitis and present an overview of the literature.
