Intra-abdominal adhesions are common after abdominal surgery. They occur more frequently after conventional laparotomy, but they can also occur after laparoscopy and can cause mechanical small bowel obstruction. The reported incidence of adhesive small bowel obstruction in children depends on the type of surgery, but it is estimated to be in 1-6% of children following abdominal surgery. This paper presented a case of a 9-year-old boy, who developed an adhesive small bowel obstruction six weeks after abdominal surgery.
