Perineal Resection of Rectum — Cost, Top Hospitals & Success Rates | MyMedicPlus

Perineal resection of the rectum is a surgical procedure in which all or part of the rectum is removed through an incision made in the perineum — the area between the anus and the genitalia — rather than through the abdomen. This approach avoids entering the abdominal cavity, making it particularly suitable for patients who are elderly, frail, or at high medical risk for abdominal surgery.

The most widely performed perineal rectal resection is the Altemeier perineal proctosigmoidectomy (also called perineal rectosigmoidectomy), which is the standard surgical treatment for full-thickness rectal prolapse in high-risk patients. In this operation, the prolapsed rectum is excised through the perineum and a coloanal anastomosis is fashioned to restore bowel continuity.

Perineal approaches to the rectum are also used in abdominoperineal resection (APR), where the rectum is removed as part of a combined abdominal and perineal procedure for low rectal cancers. The perineal component of APR involves excision of the anus, distal rectum, and surrounding tissue, resulting in a permanent colostomy.

The perineal approach has the major advantage of avoiding abdominal wall incision, reducing the risk of wound complications, ileus, and the physiological stress of laparotomy — making it particularly valuable in geriatric and high-risk populations.

Perineal resection of the rectum is indicated for several anorectal and colorectal conditions:

• Full-thickness rectal prolapse (complete rectal prolapse) — the most common indication for the Altemeier procedure; the entire rectal wall protrudes through the anus, causing incontinence, mucus discharge, bleeding, and significant quality-of-life impairment
• Low rectal cancer requiring abdominoperineal resection (APR) — tumours of the distal rectum, anal canal, or levator musculature that cannot be resected with sphincter preservation; the perineal phase of APR removes the anus and surrounding tissue en bloc
• Recurrent rectal prolapse — when abdominal rectopexy (primary surgery) has failed, a perineal approach may be chosen for its lower morbidity in re-operative cases
• Refractory faecal incontinence with structural defects — selected cases of incontinence associated with rectal pathology may benefit from resection
• Solitary rectal ulcer syndrome — chronic straining and internal prolapse associated with rectal wall ulceration may require resection in refractory cases
• Perineal descent syndrome with obstructed defaecation — selected patients with severe perineal descent causing obstructed defaecation unresponsive to conservative measures

Patient selection for perineal versus abdominal rectal resection is primarily driven by operative risk and clinical indication:

• Elderly or frail patients with rectal prolapse — the perineal approach is preferred because it avoids laparotomy and is associated with lower 30-day morbidity and mortality in high-risk patients. Age alone is not a contraindication; the Altemeier procedure has been safely performed in patients over 90
• High cardiopulmonary risk — patients with severe cardiac, pulmonary, or metabolic comorbidities who could not safely tolerate general anaesthesia and abdominal surgery; perineal procedures can often be performed under spinal or regional anaesthesia
• Low rectal cancer requiring APR — patients with tumours at or below the levator musculature where sphincter preservation (low anterior resection) is not oncologically feasible
• Previous pelvic surgery with extensive adhesions — abdominal adhesions from prior surgery increase the risk of laparotomy; a perineal approach avoids this
• Patients with confirmed full-thickness prolapse on clinical examination and/or defaecography — internal intussusception alone (incomplete prolapse) is generally not treated with resection

Absolute contraindications include inability to position for the lithotomy or prone jackknife position, and active anorectal sepsis requiring primary drainage before definitive surgery.

Several perineal surgical approaches to the rectum are used depending on indication:

1. Altemeier Perineal Proctosigmoidectomy

The standard perineal operation for full-thickness rectal prolapse. Performed with the patient in the lithotomy or prone jackknife position under spinal or general anaesthesia. The prolapsed segment is grasped with Babcock forceps. A full-thickness circumferential incision is made in the outer layer of the prolapse 1–2 cm above the dentate line. The peritoneal pouch (pouch of Douglas) is entered anteriorly, allowing the surgeon to assess bowel length and divide the mesorectum. The redundant sigmoid colon is delivered through the perineum and resected. A hand-sewn or circular stapled coloanal anastomosis is performed at the anal verge. A concurrent levatorplasty (repair of the pelvic floor muscles) reduces recurrence rates and improves continence.

2. Delorme Procedure

An alternative perineal approach for prolapse where only the mucosa and submucosa are stripped from the prolapsed segment (mucosal sleeve resection), and the denuded muscular tube is plicated (folded and sutured) to reduce the prolapse. Less resective than the Altemeier operation; associated with higher recurrence rates but extremely low morbidity. Preferred for frail patients with limited prolapse or as an initial procedure in very high-risk individuals.

3. Perineal Phase of Abdominoperineal Resection (APR)

In APR for low rectal or anal cancer, the abdominal phase (sigmoid colostomy formation, mobilisation of the rectosigmoid) is followed by the perineal phase. The patient is repositioned prone or remains in lithotomy. An elliptical incision encircles the anus; the levator muscles, ischioanal fat, and distal rectum are excised en bloc with the specimen. The perineal wound may be closed primarily or left open to heal by secondary intention or be reconstructed with a myocutaneous flap (for extended resections or post-radiation cases).

4. Robotic or Laparoscopic-Assisted Perineal Resection

Minimally invasive abdominal mobilisation combined with a perineal extraction/resection reduces abdominal incision size while maintaining the benefits of the perineal approach. Used in selected centres with advanced laparoscopic or robotic colorectal surgery capability.

The perineal approach to rectal resection offers distinct clinical advantages, particularly in older and high-risk patients:

• Avoids laparotomy — no abdominal incision means reduced risk of ileus, wound dehiscence, incisional hernia, and abdominal wall complications
• Suitable for high-risk patients — can be performed under spinal or regional anaesthesia, reducing cardiopulmonary risk for patients who cannot safely undergo general anaesthesia
• Shorter operative time — Altemeier and Delorme procedures are typically completed in 1–2 hours; faster than equivalent abdominal procedures
• Earlier return to function — without abdominal surgery, bowel function returns more quickly and recovery time is shorter
• Effective for rectal prolapse — the Altemeier procedure eliminates the prolapse in the majority of patients, restoring quality of life by resolving mucus discharge, bleeding, and incontinence
• Concurrent pelvic floor repair — levatorplasty or anterior repair can be performed at the same time, addressing co-existing pelvic floor weakness
• Oncological adequacy — the perineal component of APR achieves en bloc resection of the anus, rectum, and surrounding tissue with clear margins in appropriately selected rectal cancer patients

As with all rectal surgery, perineal resection carries specific risks:

Early Complications

• Anastomotic leak — breakdown of the coloanal anastomosis following proctosigmoidectomy occurs in 3–8% of cases; may present as pelvic sepsis, peritonitis, or anastomotic fistula; may require temporary diverting stoma
• Bleeding — intraoperative or postoperative haemorrhage from mesenteric vessels or anastomotic bleeding; transfusion or re-operation may be required
• Wound infection — perineal wound infection or dehiscence, particularly in APR where the perineal wound is large and the perineal space is prone to haematoma formation
• Urinary retention — common in the immediate postoperative period due to proximity of pelvic nerves; a urinary catheter is routinely placed intraoperatively
• Injury to pelvic nerves — risk of damage to parasympathetic and sympathetic nerves controlling bladder and sexual function; more relevant in APR than in perineal prolapse repair

Late Complications

• Recurrence of rectal prolapse — the main limitation of perineal resection vs. abdominal rectopexy; prolapse recurrence rates of 10–30% over 5 years vs. 2–8% for abdominal rectopexy are consistently reported
• Faecal incontinence — may persist or worsen despite prolapse repair due to pre-existing sphincter weakness or pudendal nerve damage; biofeedback therapy may help
• Anastomotic stricture — narrowing of the coloanal anastomosis causing obstructed defaecation; usually amenable to endoscopic dilation
• Phantom rectum and perineal pain — following APR, some patients experience phantom rectal sensations or chronic perineal pain; managed with physiotherapy and neuromodulatory agents
• Sexual dysfunction — pelvic nerve injury in APR can cause erectile dysfunction in men and dyspareunia in women

Recovery after perineal rectal resection is guided by the specific procedure performed:

Immediate Postoperative Period (Days 1–3)

Patients are maintained on IV fluids and clear liquids initially. The urinary catheter is typically removed within 24–48 hours once adequate voiding is confirmed. A nasogastric tube is rarely needed as ileus is less common without abdominal surgery. Patients are mobilised early — usually the day after surgery.

Hospital Discharge (Days 3–7)

Bowel function typically returns within 2–4 days following proctosigmoidectomy. Patients are discharged once they are tolerating a soft diet, pain is controlled orally, and the wound is clean. Those with APR receive stoma nursing education before discharge.

Wound Care

Perineal wounds are dressed regularly. APR perineal wounds may be left open to granulate or closed with flaps; complex wounds require specialist wound care nursing for 4–8 weeks. Sitz baths (warm water soaks) can provide comfort and promote healing for anal wounds.

Functional Recovery (Weeks 2–8)

Bowel habits normalise gradually over 6–8 weeks. Patients with coloanal anastomosis may experience increased stool frequency initially (anastomotic syndrome), which typically improves over 3–6 months. Pelvic floor physiotherapy is recommended to improve continence and resolve any functional deficits.

Cancer Surveillance (APR patients)

Following APR for rectal cancer, surveillance includes 3–6 monthly CEA levels, annual CT scans of chest/abdomen/pelvis for 3–5 years, and colonoscopy at 1 and 3 years to detect anastomotic or metachronous disease.

Prolapse Follow-Up

Patients are reviewed at 6 weeks and 6 months for clinical assessment of continence and prolapse recurrence. Biofeedback therapy for faecal incontinence and dietary fibre optimisation are initiated as needed.

The cost of perineal rectal resection varies based on several determinants:

• Procedure type — Delorme mucosectomy is less resource-intensive than Altemeier proctosigmoidectomy; APR is the most extensive and costly
• Anaesthesia approach — spinal anaesthesia is less expensive than general anaesthesia; regional anaesthesia teams add cost compared to standard anaesthetic management
• Hospital stay duration — 3–7 days for uncomplicated cases; complications such as anastomotic leak requiring ICU care and re-operation substantially increase total cost
• Stoma supplies (APR) — patients with permanent colostomy after APR incur lifelong stoma supply costs (bags, appliances, skin barriers); typically USD 100–300 per month
• Country and centre — colorectal resection in the USA costs USD 20,000–60,000; comparable surgery in India costs USD 3,000–10,000 and in Thailand USD 5,000–12,000 at accredited centres
• Oncology adjuncts — patients undergoing APR for rectal cancer typically require neoadjuvant chemoradiotherapy, adding several thousand dollars to total treatment cost
• Post-operative rehabilitation — pelvic floor physiotherapy, biofeedback, and stoma nurse specialist input add further costs in the recovery phase

Alternative surgical and non-surgical options exist depending on the underlying indication:

For Rectal Prolapse

• Abdominal rectopexy (laparoscopic or robotic) — the gold standard for fit patients; the rectum is mobilised and fixed to the sacral promontory with mesh or suture, with or without sigmoid resection; lower recurrence rates (2–8%) than perineal approaches but requires abdominal surgery
• Laparoscopic ventral mesh rectopexy (VMR) — a posterior mesh-free technique popularised by D'Hoore; particularly effective for combined rectal prolapse and posterior compartment defects in women; very low recurrence rates
• Delorme procedure — conservative mucosal plication suitable for very elderly or frail patients with limited prolapse extent
• Pelvic floor physiotherapy and biofeedback — for patients with early or reducible prolapse who are not surgical candidates; manages symptoms rather than correcting anatomical defect

For Low Rectal Cancer

• Intersphincteric resection (ISR) — in selected very-low rectal cancers, ultra-low anterior resection with intersphincteric dissection can preserve the external sphincter and avoid permanent colostomy
• Transanal total mesorectal excision (TaTME) — a hybrid approach where the mesorectum is dissected from below (transanally) and above (laparoscopically); allows sphincter preservation in select low rectal cancers previously requiring APR
• Neoadjuvant chemoradiotherapy with organ preservation — selected patients with complete clinical response after chemoradiotherapy may be managed with a watch-and-wait strategy, avoiding surgery altogether
