Transanal evisceration of the small bowel is a rare surgical emergency. Rectal perforation in such cases is usually due to an underlying rectal prolapse. We report a case of a middle aged (45 years) male with spontaneous rectal perforation and transanal evisceration of the small bowel. Approximately 150 cm of small bowel had eviscerated transanally and the patient required emergent abdominal exploration, reposition of the small bowel, and repair of the rectal perforation. Small bowel evisceration through the anal verge is an emergent condition and the aim was to prevent life threatening complications related to sepsis.
