An Unusual Cause of Adult Ileoileal Intussusception.

Intestinal intussusception in adults is not considered to be common. Clinical presentations may range from an acute presentation to a chronic one and such wide variations make it challenging to establish the diagnosis on time. Adult intussusceptions usually have an identifiable pathological lead point: commonly a polyp, submucosal lipoma, or other tumors.

Noniatrogenic Colorectal Barotrauma with Extraperitoneal Rectal Injury.

We present the case of a 22-year-old male who presented to us with abdomen discomfort with subcutaneous emphysema in the abdomen and lower chest, following a prank played by his friend who had inserted a nozzle through his anal orifice and pumped high-pressure condensed air through it. Computed tomography showed evidence of air pockets in the ischiorectal fossa and pelvis. Intraoperatively, we found large-bowel and small-bowel distension with large-bowel serosal tears and rectal tears.
