Colorectal laceration after manual-anal intercourse.

Injuries and illnesses related to changing sexual behaviors are being reported with increasing frequency. A practice found predominantly in the homosexual community, "handballing," may result in occult but serious colorectal trauma. Described is the case of a 31-year-old man who presented with an acute abdomen due to colorectal laceration secondary to handballing. After emergency surgical repair, he had an uneventful recovery, and returned once for elective colostomy closure.
