Delorme’s Procedure

This is an operation that is performed on the back passage to repair an external rectal prolapse.

The operation performed in the Birmingham Bowel Clinic involves operating through the back passage (anus) itself.

There are other methods to repair an external rectal prolapse and the surgeon will discuss these with you.


What does the operation involve?

An enema is usually given an hour or so before the operation to clear the lower part of the bowel. The operation is performed under a general anaesthetic but can be carried out under a spinal anaesthetic. During the operation itself the lining (mucosa) is stripped off the prolapse to expose the muscle of the bowel wall. When all the lining has been stripped, the muscle is bunched up with stitches to get rid of the prolapse.

The excess lining (mucosa) is then trimmed and stitched back to cover the repair. The operation takes around 60 minutes to complete.


What are the risks?

There are small risks associated with any operation. Pre-operative assessments are made of any heart or lung conditions, as well as any co-existing medical condition. During the hospital admission patients wear stockings and are given a regular tiny injections to prevent thrombosis (blood clots).

Bleeding is very rare in this type of surgery, most patients will notice small amounts of blood on the stools when they open their bowels soon after the operation. This usually settles in the first week.

Occasionally the lining of the bowel may separate at the stitch line. This rarely causes a problem but patients may notice that they continue to pass a little blood for longer than normal after the procedure.

If the patient has problems with bowel control and often this will improve after the surgery but if it doesn’t further tests, such as anorectal physiology and endo anal ultrasound or treatment may be required.


What happens after the operation?

A Delorme’s procedure doesn’t usually cause much pain afterwards. Most patients will need only simple oral painkillers after the first 24 hours.

A drip is normally in place for 24 hours after the operation.

Patients are allowed to eat and drink as soon as they feel able after the operation (usually the same day).

A catheter (tube passed into the bladder) if required during the procedure is usually removed the day after surgery.

Hospital stay is usually 3-5 days. After the operation patients are given as regular stool softener to take for 4-6 weeks and are advised to avoid straining.

Patients are encouraged to keep mobile after the procedure. They should avoid heavy lifting or increased physical activities for about 6 weeks. Patients can normally resume driving after about 2 weeks but this may vary.
