Title: Engineering Functional Preservation in Hemorrhoid Surgery: A Retrospective Evaluation of the 5PF Technique and Its Global Health Relevance

Abstract

Background: Hemorrhoids are a leading cause of surgical outpatient visits globally, yet they remain a neglected aspect of health systems planning. In this retrospective study, we present the 5PF (Precise, Purposeful, Predictable, Personalized, and Function-Preserving Fibrosis) technique, which redefines hemorrhoid surgery around the principles of functional preservation and anatomical integrity, particularly suited to resource-limited environments.

Methods: We evaluated 187 consecutive patients with grade III/IV hemorrhoids treated using 5PF at a 15-bed surgical center in India, with follow-up ranging from 1 to 13 years. The technique avoids resection and dressing, instead using controlled submucosal fibrosis to stabilize prolapse. Outcomes were categorized using clinical recurrence, complication severity, and recovery metrics.

Findings: No recurrence of prolapse, bleeding, stricture, or incontinence was observed. 100% of patients experienced bleeding/prolapse; constipation (78%), itching (31%), and pain (20%) were also common. Most patients (86%) were discharged within 24 hours. No reoperations, abscesses, or fistulas were reported. Postoperative complications were limited to manageable urinary retention (15%), prolonged reddish discharge (21%), pruritus, and minor skin tags. Pain resolved within 10 days in nearly all patients.

Interpretation: 5PF represents a shift from excision-based to architecture-preserving

approaches in benign anorectal disease. Its safety, reproducibility, and cost-effectiveness make it

relevant to the goals outlined in The Lancet Commission on Global Surgery. Prospective validation with standardized patient-reported outcomes and comparative trials is the next imperative.

Funding: No external funding was received.

Introduction

Hemorrhoidal disease contributes substantially to global surgical demand, yet treatment remains inconsistent and, in low-resource settings, largely unmet. Excisional hemorrhoidectomy, though effective, is associated with pain, delayed recovery, and functional risks such as incontinence or stricture. In LMICs, surgical access is limited and often delayed due to fear, stigma, or logistical barriers.

The Lancet Commission on Global Surgery emphasized the need for high-value, scalable solutions for common surgical problems. The 5PF technique was developed in response to these challenges: to provide a safe, teachable, and function-preserving alternative for high-volume benign anorectal disease.

Methods

This retrospective longitudinal study was conducted at a single surgical center with a dedicated practice in colorectal and oncologic surgery. Consecutive patients with grade III/IV internal and external hemorrhoids—including circumferential prolapse—were included. Patients were followed for a minimum of 12 months, with some tracked up to 13 years.

Surgical Technique: The 5PF method uses controlled fibrosis to reinforce prolapsed hemorrhoidal tissue. Key principles include:

  • Submucosal and subdermal suture techniques sparing epithelium
  • No external excision or cutting
  • No dressing; minimal postoperative care
  • Short learning curve and reproducibility

Data Collection: Outcomes were assessed across three domains:

  1. Recurrence: Bleeding, prolapse, stricture, or incontinence
  2. Complication severity: Categorized as critical, important, or minor
  3. Recovery: Pain, urinary retention, discharge, hospital stay

Results

Out of 187 patients (123 males, 64 females), all presented with prolapse and/or bleeding. Constipation (146), itching (57), and pain (38) were common. Key outcomes:

  • Recurrence: None observed clinically or via patient follow-up
  • Pain: Moderate-to-severe in all patients; controlled with analgesics, local anesthesia, and fentanyl patches. Resolved in <10 days (1 case: 22 days)
  • Complications: No reoperation, bleeding, fistula, or dressing-related issues
  • Urinary Retention: Occurred in 28 cases; associated with age/obesity; resolved with catheterization

  • Reddish Discharge: Lasted 10–40 days in some; not mistaken for bleeding due to preoperative education
  • Hospital Stay: 161 discharged day after surgery, 17 stayed 1 extra day, 9 for 2 days

Discussion

The 5PF technique offers an architecture-preserving paradigm for hemorrhoid management. By avoiding excision and focusing on functional outcomes, it challenges the historical reliance on resective models. With no major complications and high patient satisfaction in a 13-year follow- up range, 5PF suggests recurrence is not inevitable but modifiable.

Its suitability for low-resource contexts stems from:

  • Minimal infrastructure and training requirements
  • Absence of consumables or dressing needs
  • Faster return to routine activities

5PF aligns with priorities in global surgery, particularly for LMICs, where backlog of benign conditions demands locally relevant, cost-conscious, and high-safety interventions.

Limitations

  • Retrospective design without control group
  • No imaging or endoscopy-based recurrence validation
  • Lack of standardized PROMs (to be integrated prospectively)
  • Cost-effectiveness not yet quantified in DALY/QALY terms

Conclusion

The 5PF technique demonstrates encouraging outcomes and aligns with principles of equity, access, and anatomical function preservation. Its simplicity and reproducibility warrant global attention. Further validation is essential through multicenter studies, comparative trials, and integration into surgical training programs.
