Surgical Classification of Hemorrhoids
Hemorrhoids (piles) arise from congestion of internal and/or external venous plexuses around the anal canal. They are classified, depending on severity, into four degrees. First degree hemorrhoids bleed but do not prolapse outside of the anal canal; second degree prolapse outside of the anal canal, usually upon defecation, but retract spontaneously. Third degree hemorrhoids require manual placement back inside of the anal canal after prolapsing, and fourth degree hemorrhoids consist of prolapsed tissue that cannot be manually replaced and is usually strangulated or thrombosed. Symptoms associated with hemorrhoids include pain, bleeding, puritus ani (itching) and mucus discharge. In IV degree prolapse, the area where the rectal mucous membrane meets the anal skin (the dentate line) is positioned almost outside the anal canal, and the rectal mucous membrane permanently occupies the muscular anal canal.

For more detailed about information, about the concepts of hemorrhoidal anatomy as applied to rectal surgery, view our video on Overview: Anatomy of Prolapse and Hemorrhoids > get Real Player , an alternative approach to the surgical treatment of hemorrhoids. In order to explain the rational of the surgical procedure for prolapse and hemorrhoids it is helpful to take a moment to review some concepts of anatomy.

Traditional Surgery
In many cases hemorrhoidal disease can be treated by dietary modifications, topical medications and soaking in warm water, which temporarily reduce symptoms of pain and swelling. Additionally, painless non-surgical methods of treatment are available to most of our patients as a viable alternative to a permanent hemorrhoid cure.

In a certain percentage of cases, however, surgical procedures are necessary to provide satisfactory, long?term relief. In cases involving a greater degree of prolapse, a variety of operative techniques are employed to address the problem.

Milligan-Morgan Technique
Developed in the United Kingdom by Drs. Milligan and Morgan, in 1937. The three major hemorrhoidal vessels are excised. In order to avoid stenosis, three pear-shaped incisions are left open, separated by bridges of skin and mucosa. This technique is the most popular method, and is considered the gold standard by which most other surgical hemorrhoidectomy techniques are compared.

Ferguson Technique
Developed in the United States by Dr. Ferguson, in 1952. This is a modification of the Milligan-Morgan technique (above), whereby the incisions are totally or partially closed with absorbable running suture.

Furgeson Technique

A retractor is used to expose the hemorrhoidal tissue, which is then removed surgically. The remaining tissue is either sutured or is sealed through the coagulation effects of a surgical device.

Due to the high rate of suture breakage at bowel movement, the Ferguson technique brings no advantages in terms of wound healing (5-6 weeks), pain, or postoperative morbidity.

Conventional haemorrhoidectomy can be performed as a day-case procedure. But due to poor post-operative care in the community and high level of pain experienced after the procedure, an in-patient stay is often required (average of 3 days).

Stapled Hemorrhoidopexy (PPH Procedure)
Also known as Procedure for Prolapse & Hemorrhoids (PPH), Stapled Hemorrhoidectomy, and Circumferential Mucosectomy.

PPH is a technique developed in the early 90's that reduces the prolapse of hemorrhoidal tissue by excising a band of the prolapsed anal mucosa membrane with the use of a circular stapling device. In PPH, the prolapsed tissue is pulled into a device that allows the excess tissue to be removed while the remaining hemorrhoidal tissue is stapled. This restores the hemorrhoidal tissue back to its original anatomical position.

The introduction of the Circular Anal Dilator causes the reduction of the prolapse of the anal skin and parts of the anal mucous membrane. After removing the obturator, the prolapsed mucous membrane falls into the lumen of the dilator.

The Purse-String Suture Anoscope is then introduced through the dilator.

This anoscope will push the mucous prolapse back against the rectal wall along a 270° circumference, while the mucous membrane that protrudes through the anoscope window can be easily contained in a suture that includes only the mucous membrane. By rotating the anoscope, it will be possible to complete a purse-string suture around the entire anal circumference.

The Hemorrhoidal Circular Stapler is opened to its maximum position. Its head is introduced and positioned proximal to the purse-string, which is
then tied with a closing knot.


The ends of the suture are knotted externally. Then the entire casing of the stapling device is introduced into the anal canal. During the introduction, it is advisable to partially tighten the stapler.

With moderate traction on the purse-string, a simple maneuver draws the prolapsed mucous membrane into the casing of the circular stapling device. The instrument is then tightened and fired to staple the prolapse. Keeping the stapling device in the closed position for approximately 30 seconds before firing and approximately 20 seconds after firing acts as a tamponade, which may help promote hemostasis.

Firing the stapler releases a double staggered row of titanium staples through the tissue. A circular knife excises the redundant tissue. A circumferential column of mucosa is removed from the upper anal canal. Finally, the staple line is examined using the anoscope. If bleeding from the staple line occurs, additional absorbable sutures may be placed.

What are the Benefits of PPH over other Surgical Procedures?
1) Patients experience less pain as compared to conventional techniques.
2) Patients experience a quicker return to normal activities compared to those treated with conventional techniques.
3) 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:
4) If too much muscle tissue is drawn into the device, it can result in damage to the rectal wall.
5) The internal muscles of the sphincter may stretch, resulting in short-term or long-term dysfunction.
6) As with other surgical treatments for haemorrhoids, cases of pelvic sepsis have been reported following stapled haemorrhoidectomy.
7) 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.
8) Persistent pain and fecal urgency after stapled hemorrhoidectomy, although rare, has been reported.
9)
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.

The Harmonic Scaplel uses ultrasonic technology, the unique energy form that allows both cutting and coagulation of hemorrhoidal tissue at the precise point of application, resulting in minimal lateral thermal tissue damage. Because the Harmonic Scaplel uses ultrasound, there is less smoke than is generated by both lasers and electrosurgical instruments. The Harmonic Scaplel cuts and coagulates by using lower temperatures than those used by electrosurgery or lasers. Harmonic Scaplel technology controls bleeding by coaptive coagulation at low temperatures ranging from 50ēC to 100ēC: vessels are coapted (tamponaded) and sealed by a protein coagulum. Coagulation occurs by means of protein denaturation when the blade, vibrating at 55,500 Hz, couples with protein, denaturing it to form a coagulum that seals small coapted vessels. When the effect is prolonged, secondary heat is produced that seals larger vessels. Because ultrasound is the basis for Harmonic Scaplel technology, no electrical energy is conducted to the patient.

By contrast, electrosurgery coagulates by burning (obliterative coagulation) at temperatures higher than 150ēC. Blood and tissue are desiccated and oxidized (charred), forming eschar that covers and seals the bleeding area. The reduced postoperative pain after Harmonic Scalpel hemorrhoidectomy compared with electrocautery controls, likely results from the avoidance of lateral thermal injury.


Harmonic Scalpel Applied to Tissue
Harmonic Scalpel Hemorrhoidectomy

The protein coagulum caused by the application of the Harmonic Scaplel is superior at sealing off large bleeding vessels during surgery. It has been my experience that this method is useful on large hemorrhoids that may bleed during surgery, thus minimizing blood loss and reducing the time needed for surgery.

Laser Surgery for Hemorrhoids
Skilled surgeons use laser light with pinpoint accuracy. The unwanted hemorrhoid is simply vaporized or excised. The infinitely small laser beam allows for unequaled precision and accuracy, and usually rapid, unimpaired healing.

The result is less discomfort, less medication, and faster healing. A hospital stay is generally not required. The laser is inherently therapeutic, sealing off nerves and tiny blood vessels with an invisible light. By sealing superficial nerve endings patients have a minimum of postoperative discomfort. With the closing of tiny blood vessels, your proctologist is able to operate in a controlled and bloodless environment.

Procedures can often be completed more quickly and with less difficulty for both patient and physician. Laser can be use alone or in combination with other modalities.

A study of 750 patients undergoing laser treatment for hemorrhoids reported successful results of 98%. The patient satisfaction was 99%.

Atomizing Hemorrhoids
A new technique to remove hemorrhoids is called atomizing. The Atomizer™ is a medical device that was developed specifically to atomize tissue. The term "atomizing hemorrhoids" was coined because the hemorrhoids are actually reduced to minute particles into a fine mist or spray, which is immediately vacuumed away. An innovative waveform of electrical current and a specialized electrical probe, the Atomizer Wand™, was created for this purpose (patent pending).

With a wave of the Atomizer Wand, the hemorrhoids are simply excised or vaporized one or more cell layers at a time. The hemorrhoids are essentially disintegrated into an aerosol of carbon and water molecules. Using the Atomizer, the tissue is sculpted into a desired shape and smoothness. As a
result, the surgeon operates with minimal bleeding, and gets better homeostasis than with traditional electrosurgical techniques. With the Atomizer, the patient gets better postoperative results, and fewer anal tags than with traditional operative techniques.

In the United States, the Ferguson hemorrhoidectomy is considered the gold standard by which most other surgical hemorrhoidectomy techniques are compared. A clinical study at the Hemorrhoid Care Medical Clinic, of thirty patients, compared the traditional Ferguson hemorrhoidectomy with the CO2 laser hemorrhoidectomy, and the Atomizer hemorrhoidectomy, and revealed the following:

Atomizer Graph

Figure 1: Hemorrhoidectomy: Atomizing vs. the CO2 laser.

The results of atomizing hemorrhoids are similar to that of lasering hemorrhoids, except that there is less bleeding using the Atomizer, and the Atomizer cost less. In both procedures, it is noted that there is less discomfort, less medication, less constipation, less urinary retention, and a hospital stay is generally not required. Complications using the Atomizer are rare, and excellent results are typical.

Atomizing hemorrhoids is offered exclusively in Arizona.

Complications of Hemorrhoid Surgery

Early Complications Include:
1) Severe postoperative pain, lasting 2-3 weeks. This is mainly due to incisions of the anus, and ligation of the vascular pedicles.
2) Wound infections are uncommon after hemorrhoid surgery. Abscess occurs in less than 1% of cases. Severe necrotizing infections are rare.
3) Postoperative bleeding.
4) Swelling of the skin bridges.
5) Major short-term incontinence.
6) Difficult urination. Possibly secondary to occult urinary retention, urinary tract infection develops in approximately 5% of patients after anorectal surgery. Limiting postoperative fluids may reduce the need for catheterization (from 15 to less than 4 percent in one study).

Late Complications Include:
1) Anal stenosis.
2) Formation of skin tags.
3) Recurrence.
4) Anal fissure.
5) Minor incontinence.
6) Fecal impaction after a hemorrhoidectomy is associated with postoperative pain and narcotic use. Most surgeons recommend stimulant laxatives, or stool softeners to prevent this problem. Removal of the impaction under anesthesia may be required.
7) Delayed hemorrhage, probably due to sloughing of the vascular pedicle, develops in 1 to 2 percent of patients. It usually occurs 7 to 16 days postoperatively. No specific treatment is effective for preventing this complication, which usually requires a return to the operating room for one or more stitches.

Knowing What to Ask Your Surgeon
Before choosing the procedure you wish to have performed, there are questions you should ask the surgeon:
1. What types of procedures have they performed?
2. How many of each procedure have they performed?
3. Why are they recommending one particular procedure over another?
4. How long will the procedure take?
5. Will this procedure require a hospital stay and how long do they anticipate your hospital stay will last?
6. How long do they expect the recovery process to take?
7. How soon will you be able to return to "normal" activity?
8. Will having the procedure mean having to change how I live, work or eat?
