Transanal Small Bowel Eviceration due to Traumatic Rectal Perforation

ABSTRACT

Transanal small bowel evisceration by rectal perforation is a very rare presentation. It occurs spontaneously or in association with trauma. We experienced a 20-year-old female patient who had transanal evisceration of the small bowel due to blunt trauma. Operative findings showed traumatic rectal perforation and gangrenous change of the eviscerated small bowel due to tearing of the small bowel mesentery. Segmental resection of gangrenous small bowel with immediate anastomosis and Hartmann's procedure of rectal perforation were performed. After 9 months, reduction of sigmoid colostomy and colorectal anastomosis were performed. We report this rare case with a review of the literature.
