Hartmann's procedure

Hartmann's procedure, also sometimes called a proctosigmoidectomy, is an operation to remove part of the sigmoid colon and/or the rectum.

This may be done in an emergency if the bowel becomes blocked or perforated, or as a planned treatment for bowel cancer or diverticular disease.

The procedure is carried out under general anaesthetic and can be done as keyhole surgery using a laparoscope through small incisions, or through open surgery.

During the operation, the removal of the diseased or damaged part of the sigmoid colon, and/or the rectum as appropriate, first requires lymph nodes and blood vessels in the area to be taken out.

The remaining rectum is sealed with surgical staples or sutures.

Surgeons may be able to join up the two parts of the bowel afterwards, but if not, a special waste tube will be fitted leading to a colostomy bag.

The operation should take around 3 hours.

Samples of the tissue removed may be sent for laboratory testing.

Risks of the procedure include bleeding, infections, pain and the bowel being slow to begin working again.

Surgical drainage tubes and a catheter will be removed some time after the operation.

Discharge from hospital will be after around 5-7 days for keyhole operations or 7-10 days for open surgery.

Instructions will be given for home care of wounds, and when to resume various activities.

Details will also be given of what to do in the event of problems or concerns.

A follow-up appointment should also be made.
