case_images: Examination of the abdomen revealed a prolapsed stoma that was 20 cm in length (Fig. 1a), swollen with edematous change, and somewhat firm. When we reattempted manual reduction, the prolapsed stoma developed a rupture about 5 cm in length (Fig. 1b).
case_images: Intraoperative findings. a The small intestine incarcerated in the aperture made when the colostomy was formed (arrowheads). b Schema. (i) Normal end colostomy. (ii) Stoma prolapse in end colostomy. (iii) Intrastomal hernia in this case. The incarcerated small bowel herniated into the stoma mimicking stoma prolapse.
