The LAR procedure involves which type and location of ostomy?

• A. Permanent colostomy in the LLQ
• B. Two distinct stomas in the RLQ
• C. Temporary ileostomy in RLQ
• D. Loop ileostomy in the LUQ

Answer: (C)

After a low anterior resection, the aim is to remove the diseased rectum while preserving the anal sphincter, and surgeons often protect the healing connection by creating a temporary diverting ostomy. This ostomy is an ileostomy, bringing ileum to the surface to divert stool away from the anastomosis, and it is usually placed in the right lower quadrant. It’s intended to be temporary, allowing reversal once healing is confirmed. Therefore, the best description is a temporary ileostomy in the right lower quadrant. The other scenarios aren’t typical for this procedure: a permanent colostomy would negate sphincter preservation, having two stomas is unnecessary, and a loop ileostomy in the left upper quadrant is unlikely in standard LAR practices.
