How does it work?
Using a hemorrhoidal circular stapler device, the procedure for prolapse and hemorrhoids procedure essentially "lifts up," or repositions the mucosa, or anal canal tissue, and reduces blood flow to the internal hemorrhoids. These internal hemorrhoids then typically shrink within four to six weeks after the procedure. The PPH procedure results in less pain than traditional hemorrhoidectomy procedures because it is performed above the area where a person would feel pain, or dentate line inside the anal canal. The advantage is that this hemorrhoid treatment method affects few nerve endings, while traditional hemorrhoidectomy procedures are performed below the dentate line, affecting many sensitive nerve endings.
What are the Benefits of PPH over other Surgical Procedures?
Patients experience less pain as compared to conventional techniques.
Patients experience a quicker return to normal activities compared to those treated with conventional techniques.
Mean inpatient stay was lower compared to patients treated with conventional techniques.
What are the Risks of PPH?
Although rare, there are risks that accompany PPH:
If too much muscle tissue is drawn into the device, it can result in damage to the rectal wall.
The internal muscles of the sphincter may stretch, resulting in short-term or long-term dysfunction.
As with other surgical treatments for haemorrhoids, cases of pelvic sepsis have been reported following stapled haemorrhoidectomy.
PPH may be unsuccessful in patients with large confluent hemorrhoids. Gaining access to the anal canal can be difficult and the tissue may by too bulky to be incorporated into the housing of the stapling device.
Persistent pain and fecal urgency after stapled hemorrhoidectomy, although rare, has been reported.
Stapling of hemorrhoids is associated with a higher risk of recurrence and prolapse than conventional hemorrhoid removal surgery; according to a Canadian study of 537 participants.
