Introduction

Hemorrhoids, commonly known as piles, are one of the most common anorectal disorders affecting millions of people worldwide. Patients suffering from advanced hemorrhoids often experience symptoms such as bleeding during bowel movements, prolapse of tissue outside the anus, pain, itching, discomfort, mucus discharge, and difficulty maintaining hygiene. Traditional open hemorrhoid surgery has long been considered an effective treatment, but it is often associated with significant postoperative pain and prolonged recovery.

With the advancement of minimally invasive surgical techniques, Stapled Hemorrhoidopexy, also known as Procedure for Prolapse and Hemorrhoids (PPH), has emerged as a modern and patient-friendly alternative for the treatment of advanced prolapsing hemorrhoids. This technique offers reduced postoperative pain, shorter hospital stay, quicker recovery, and improved patient comfort compared to conventional hemorrhoidectomy.

Understanding Advanced Hemorrhoids

Hemorrhoids are swollen vascular cushions located in the anal canal. They become symptomatic when enlarged, inflamed, or prolapsed. Advanced hemorrhoids generally refer to Grade III and Grade IV internal hemorrhoids.

Classification of Hemorrhoids

• Grade I: Bleeding hemorrhoids without prolapse.
• Grade II: Prolapse during straining but reduce spontaneously.
• Grade III: Prolapse requiring manual reduction.
• Grade IV: Permanently prolapsed and irreducible hemorrhoids.

Patients with advanced hemorrhoids frequently complain of:

• Rectal bleeding
• Prolapse of hemorrhoidal tissue
• Pain and discomfort
• Itching and irritation
• Mucus discharge
• Difficulty in cleaning the anal area
• Feeling of incomplete evacuation

What is Stapled Hemorrhoidopexy (PPH)?

Stapled Hemorrhoidopexy is a minimally invasive surgical procedure designed to treat prolapsing internal hemorrhoids. Unlike conventional hemorrhoidectomy, which removes hemorrhoidal tissue directly from the sensitive anal canal, PPH works by repositioning the prolapsed hemorrhoidal tissue back into its normal anatomical position.

The procedure utilizes a specially designed circular stapling device that excises a ring of redundant rectal mucosa above the hemorrhoids. This simultaneously lifts the prolapsed hemorrhoids and interrupts part of their blood supply, leading to shrinkage of the hemorrhoidal cushions.

Since the surgery is performed above the dentate line, an area with fewer pain-sensitive nerves, postoperative pain is significantly reduced.

Principle of the Procedure

The stapled hemorrhoidopexy procedure is based on two important principles:

1. Reduction of Hemorrhoidal Prolapse
   • The prolapsed hemorrhoidal tissue is repositioned upward into the anal canal.
2. Reduction of Blood Supply
   • The blood flow to the hemorrhoidal tissue is partially interrupted, causing shrinkage over time.

This dual mechanism effectively relieves symptoms while preserving normal anal anatomy.

Indications for Stapled Hemorrhoidopexy

PPH is commonly recommended for:

• Grade III hemorrhoids
• Grade IV hemorrhoids
• Circumferential prolapsing hemorrhoids
• Internal hemorrhoids with significant mucosal prolapse
• Patients seeking less postoperative pain and faster recovery

Contraindications

Stapled hemorrhoidopexy may not be suitable in:

• External hemorrhoids alone
• Thrombosed hemorrhoids
• Anal stenosis
• Anal fistula or abscess
• Inflammatory bowel disease
• Rectal prolapse
• Active anorectal infection

Preoperative Evaluation

Before surgery, the patient undergoes a detailed evaluation which may include:

• Medical history and physical examination
• Digital rectal examination
• Proctoscopy or anoscopy
• Colonoscopy in selected patients with rectal bleeding
• Routine blood investigations

Patients are also counseled regarding:

• Expected outcomes
• Benefits and limitations
• Possible complications
• Postoperative care

Surgical Technique of PPH

Anesthesia and Position

The procedure is usually performed under:

• Spinal anesthesia
• General anesthesia

The patient is placed in:

• Lithotomy position
• Prone jackknife position (occasionally)

Step-by-Step Procedure

1. Anal Dilatation and Introduction of Circular Anal Dilator

A circular anal dilator is inserted gently into the anal canal to expose the prolapsed hemorrhoidal tissue.

2. Placement of Purse-String Suture

A circumferential purse-string suture is placed in the rectal mucosa approximately 3–4 cm above the dentate line.

3. Introduction of Circular Stapler

The stapling device is inserted through the anal canal.

4. Tightening of Purse-String

The purse-string suture is tied around the shaft of the stapler, pulling the prolapsed mucosa into the stapler housing.

5. Firing of Stapler

The stapler is fired, excising a circumferential ring of mucosa and submucosa while simultaneously creating a stapled anastomosis.

6. Inspection for Hemostasis

The staple line is inspected carefully for bleeding and additional sutures are placed if necessary.

Advantages of Stapled Hemorrhoidopexy

1. Less Postoperative Pain

One of the biggest advantages is significantly reduced pain because the procedure avoids sensitive anoderm tissue.

2. Faster Recovery

Patients can return to normal daily activities much earlier than with traditional hemorrhoidectomy.

3. Shorter Hospital Stay

Many patients are discharged within 24 hours.

4. Preservation of Anal Anatomy

The normal anatomy and function of the anal canal are better preserved.

5. Reduced Wound Care

Since there is no large external wound, postoperative wound management becomes easier.

6. Improved Patient Satisfaction

Reduced discomfort and rapid recovery contribute to higher patient satisfaction rates.

Comparison with Conventional Hemorrhoidectomy

Postoperative Care

After surgery, patients are advised:

• High-fiber diet
• Adequate hydration
• Stool softeners
• Sitz bath
• Pain medications if required
• Avoidance of straining during defecation

Most patients recover rapidly and resume routine activities within a few days.

Possible Complications

Although generally safe, stapled hemorrhoidopexy can have complications such as:

• Bleeding
• Pain
• Urinary retention
• Staple line bleeding
• Infection
• Recurrence of hemorrhoids
• Anal stenosis
• Rectovaginal fistula (rare)
• Pelvic sepsis (extremely rare but serious)

Proper surgical expertise and patient selection significantly reduce these risks.

Recurrence and Long-Term Outcomes

Studies have shown good long-term outcomes with stapled hemorrhoidopexy, especially for prolapsing hemorrhoids. However, recurrence rates may be slightly higher than conventional excisional hemorrhoidectomy in some patients.

Despite this, the advantages of reduced pain and faster recovery make PPH an attractive option for carefully selected patients.

Recent Advances in Hemorrhoid Surgery

Modern colorectal surgery continues to evolve with techniques such as:

• Doppler-guided hemorrhoidal artery ligation
• Laser hemorrhoidoplasty
• Radiofrequency ablation
• Minimally invasive stapling devices

Stapled hemorrhoidopexy remains an important milestone in minimally invasive anorectal surgery due to its balance between effectiveness and patient comfort.

Conclusion

Stapled Hemorrhoidopexy (PPH) represents a significant advancement in the surgical management of advanced prolapsing hemorrhoids. By repositioning hemorrhoidal tissue and reducing blood supply without extensive excision, this minimally invasive technique provides effective symptom relief with less postoperative pain and faster recovery.

For patients suffering from Grade III and Grade IV hemorrhoids, PPH offers a modern alternative to conventional hemorrhoidectomy, improving overall patient experience and quality of life. Careful patient selection, proper surgical expertise, and appropriate postoperative care are essential for achieving optimal outcomes.
