Rectosigmoid screwdriver perforation presenting as a strangulated inguinal hernia.

We present a case of a young male patient with no previously known medical, surgical or psychiatric history, who was referred to our institution as an irreducible left inguinal hernia with signs of strangulation. Intraoperative findings, however, revealed a retained foreign body at the rectosigmoid junction, which had previously perforated through the floor of the inguinal canal, essentially sealing off the contamination into the inguinal canal and contributing to the clinical presentation of a left inguinal hernia. This is, to our knowledge, the first published case report locally and internationally concerning rectosigmoid-inguinal canal perforation with the working end of a screwdriver.
