See loop colostomy.
Most often a temporary colostomy with two openings into the colon: one distal and one proximal. Elimination occurs through the proximal stoma, allowing the distal length of the colon to rest and heal. When healing is complete, the two ends are rejoined and returned to the peritoneal cavity, and normal bowel function resumes. In colitis, resection rather than reanastomosis is performed.
