Altemeier's Procedure (Rectosigmoidectomy)
General remarks
- Rectal prolapse is associated with feacal incontinence in about 50-70%
- Mucosal prolapse should be distinguished from a rectal prolapse. A careful examination during straining should be performed
- The aim of the treatment is to control the prolapse and to restore continence
- Rectopexy is the treatment of choice for rectal prolapse. Those abdominal repairs involve fixing the rectum to the sacrum by using either mesh or sutures, and tend to have the lowest recurrence rates (<10%)
- Perineal surgical repairs are well tolerated, but are generally associated with higher recurrence rates
- The Altemeier procedure can be considered for elderly patients who are most likely unfit for a major abdominal procedure (e.g. rectopexy)
- The perineal approach for an Altemeier's procedure also creates the possibility to repair the pelvic floor muscles when necessary
- Recurrence rates for the Altemeier's procedure vary from 3 to 43%
Step by step
- Place patient in lithotomy position (or in prone jack-knife position)
- Prolapse should be delivered on to the perineum
- The mucosa is divided transversely at the dentate line
- While dividing the muscle layer, the submucosal vessels should be carefully cauterized
- The rectum is then withdrawn to expose the rectovaginal peritoneal pouch
- The peritoneum should be opened anteriorly and lateraly and the sigmoid colon can now be exposed
- Posterior transection of the rectum can be completed
- Mesorectum is divided and ligated
- Sigmoid colon is pulled down and the transection site can be determined
- Sigmoid mesentery is divided and ligated
- The anterior aspect of the sigmoid colon is opened
- Now the first (i.e. anterior) anastomotic suture can be placed
- The lateral aspect of the sigmoid colon is opened and the lateral anastomotic sutures can be placed
- Transection of the sigmoid colon can then be completed
- The coloanal anastomosis can now be completed with a total of about eight sutures
