Illustration of Stapled hemorrhoidopexy
Stapled hemorrhoidectomy, also known as stapled hemorrhoidopexy, is a surgical procedure that involves the removal of abnormally enlarged hemorrhoidal tissue, followed by the repositioning of the remaining hemorrhoidal tissue back to its normal anatomic position. Severe cases of hemorrhoidal prolapse will normally require surgery. Newer surgical procedures include stapled transanal rectal resection (STARR) and procedure for prolapse and hemorrhoids (PPH). Both STARR and PPH are contraindicated in persons with either enterocele or anismus.
Hemorrhoids are amongst the most common anal disorders. Patients may complain of bleeding, prolapse, personal discomfort and minor anal leakage. Where traditional non-surgical measures such as rest, suppositories and dietary advice fail to improve the condition, there is then a choice of further treatments. Opinion on the best management for patients varies considerably. While many treatments for hemorrhoids may be performed without anesthetics, the lasting effect of these conservative therapies has been questioned. Many patients treated with rubber band ligation or injection sclerotherapy require multiple treatments and there is high recurrence rate following these procedures.
Conventional hemorrhoidectomy provides permanent symptomatic relief for most patients, and effectively treats any external component of the hemorrhoids. However, the wounds created by the surgery are usually associated with considerable post-operative pain which necessitates a prolonged recovery period. This can put a stress on a general practitioner’s resources, may alienate the patient and delays the patient’s return to a full, normal lifestyle and the workplace. Because of this, surgeons will generally reserve formal excision for the most severe cases of prolapse, or for patients who have failed to respond to conventional treatments.[medical citation needed]
Stapled transanal rectal resection (STARR)
Obstructed defecation syndrome (ODS) can be caused by structural deformities in the rectum resulting in chronic constipation. A new surgical procedure, Stapled Transanal Rectal Resection (STARR), can treat ODS using minimally invasive methods. STARR is a surgical procedure that is performed through the anus, requires no external incisions, and leaves no visible scars. Using a surgical stapler, the procedure removes the excess tissue in the rectum, reducing the anatomical defects that can cause ODS.
In a study of 90 patients undergoing the STARR procedure, patients were hospitalized one to three days, experienced minimal postoperative pain after the procedure, and resumed employment or normal activity in 6 to 15 days. In this study, most ODS patients experienced a significant improvement in their ODS symptoms following STARR.
Procedure for Prolapse and Hemorrhoids (PPH)
PPH uses a circular stapler to reduce the degree of prolapse. The procedure avoids the need for wounds in the sensitive perianal area thus reducing post-operative pain considerably, and facilitates a speedier return to normal activities.
This procedure was first described by an Italian surgeon – Dr. Antonio Longo, Department of Surgery, University of Palermo – in 1993 and since then has been widely adopted through Europe. This procedure avoids the need for wounds in the sensitive perianal area and, as a result, has the advantage of significantly reducing the patient’s post operative pain. Follow-up on relief of symptoms indicate a similar success rate to that achieved by conventional haemorrhoidectomy. Since PPH was first introduced it has been the subject of numerous clinical trials and in 2003 the National Institute of Clinical Evidence (NICE) in the UK issued full guidance on the procedure stating it was safe and efficacious.
PPH is generally indicated for the more severe cases of internal hemorrhoidal prolapse (3rd and 4th degree) where surgery would normally be indicated. It may also be indicated for patients with minor degree haemorrhoids who have failed to respond to conservative treatments. The procedure may be contra-indicated when only one cushion is prolapsed or in severe cases of fibrotic piles which cannot be physically repositioned.
In addition to correcting the symptoms associated with the prolapse, problems with bleeding from the piles are also resolved by this excision. Although the cushions may be totally or partially preserved, the blood supply is interrupted or venous drainage is improved by the repositioning. Any external component which remains will usually regress over a period of 3–6 months. Prominent skin tags may, on occasion, be removed during the operation but this may increase the postoperative pain so is not routinely performed.
PPH employs a unique circular stapler which reduces the degree of prolapse by excising a circumferential strip of mucosa from the proximal anal canal. This has the effect of pulling the hemorrhoidal cushions back up into their normal anatomical position. Usually the patient will be under general anesthetic, but only for 20–30 minutes. Many cases have been successfully performed under local or regional anesthesia and the procedure is suited to day case treatment.
Post operative course
Due to the low level of post-operative pain and reduced analgesic use, patients will usually be discharged either the same day or on the day following surgery. Most patients can resume normal activities after a few days when they should be fit for work. The first bowel motion is usually on day two and should not cause any great discomfort. Staples may be passed from time to time during defecation. This is normal and should not be a cause for concern.[medical citation needed]
Since 2002 more than 100 articles have been published reporting complications during and after stapled hemorroidectomy.
Short term complications
Bleeding is the most common postoperative complication. Severe postoperative pain could be caused by dehiscence of the anastomosis or due to the fact that the anastomosis is too near to the linea dentata. A rare complication stemming from PPH is intra-abdominal bleeding.
Long term complications
A lot of long term complications have been described. Most of them are related to either an incorrect indication for surgery or technical errors. Several authors stated that although it seems to be an easy operation to perform, it should only be done by experienced surgeons. Severe complications leading to death have been described but are rare. Irreversible urge incontinence due to lesions of the sphincter muscle or a diminished rectal capacity due to resection of too much mucosa, are quite common complications if the procedure is not performed properly. Rectovaginal fistulas and anastomotic diverticula are very rare but possible.
