Study summary

This prospective randomized controlled trial will include adult patients with ODS, anterior rectocele ≥3 cm, and excessive perineal descent following failure of conservative treatment.

Patients will be randomized 1:1 to STARR alone or STARR combined with transverse perineal support procedure using polypropylene mesh. The primary outcome will be Change in Obstructed Defecation Syndrome score (ODS-S; Renzi score) in both groups. Secondary outcomes will include operative time, postoperative pain, surgical complications, surgical site infection, and sexual function assessed using the PISQ-12. Patients will be followed up twice during the first postoperative week, weekly during the first month, and monthly thereafter.

Read the detailed description

This will be a prospective, randomized controlled trial conducted at Kasr Al-Ainy Hospitals, Cairo University, including adult patients of either sex with obstructed defecation syndrome (ODS) associated with rectocele, and excessive perineal descent. Eligible patients must have anterior rectocele ≥3 cm, excessive perineal descent, and failure of conservative treatment. Patients with Slow-transit constipation, anterior rectocele of \< 3 cm, complete external rectal prolapse, evidence of colorectal carcinoma or Inflammatory bowel disease ( IBD), Patients with fecal incontinence, Inability for lifestyle change postoperatively, or previous surgeries for anterior rectocele will be excluded.

Following informed written consent, Eligible participants will be randomized in a 1:1 ratio using computer-generated randomization, with allocation concealment through sequentially numbered, opaque, sealed envelopes.

Patients will be allocated to either Group A (STARR alone) or Group B (STARR combined with transverse perineal support using non-absorbable polypropylene mesh). Postoperative assessment will include operative time, pain using the visual analogue scale, and postoperative complications.

Patients will be followed-up twice weekly in the first postoperative week, weekly during the first month, and monthly thereafter. The primary outcome will be Change in Obstructed Defecation Syndrome score (ODS-S; Renzi score) in both groups. Secondary outcomes will include operative time, postoperative pain, surgical site infection, sexual function assessed by Pelvic Organ Prolapse/Urinary incontinence sexual questionnaire (PISQ-12), and postoperative complications.

    STARR procedure

    STARR will be done using PPH circular stapler to achieve trans-anal full-thickness resection of the rectocele

    Procedure: STARR Procedure

  • Experimental
    STARR combined with transverse perineal support procedure

    Transverse perineal support procedure will be added to the STARR procedure. Transverse perineal support procedure will be done using a non-absorbable polypropylene mesh to reinforce the perineal body and correct excessive perineal descent.

What researchers measure

Primary outcomes

  1. Change in Obstructed Defecation Syndrome score (ODS-S; Renzi score) in both groups.

    Compare Change in Obstructed Defecation Syndrome score (ODS-S; Renzi score) in both groups. Obstructed Defecation Syndrome score (ODS-S; Renzi score) ranges from 0 to 20. Higher scores indicate a worse outcome (more severe obstructed defecation symptoms )

    Time frame: Up to 6 months postoperatively

Secondary outcomes

  1. Operative time

    Compare time of operation between both procedure

    Time frame: During surgery

  2. Number of participants with surgical site infection

    compare surgical site infection in both groups (surgical site infection: infection at or near a surgical incision within 30 days post-surgery, marked by redness, swelling, or pus.)

    Time frame: Up to 6 months postoperatively

  3. Postoperative urine retention

    Compare incidence of postoperative urine retention in both groups. (Postoperative urinary retention: inability to void spontaneously after surgery with a bladder volume ≥500 mL on bladder ultrasound).

    Time frame: Within 48 hours postoperatively

  4. Pain intensity

    Compare Pain intensity measured using Visual Analogue Scale between both groups (Visual Analogue Scale for Pain: ranges from 0 to 10 . Higher scores indicate a worse outcome {greater pain intensity})

    Time frame: Up to 6 months postoperatively

  5. Sexual Function in both groups

    Compare sexual function in both groups using Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ- 12). PISQ-12 score ranges from 0 to 48. Higher scores indicate better sexual function

    Time frame: Up to 6 months postoperatively

  6. Hospitalization period

    Compare how many days patients stay in hospital in both groups

    Time frame: From date of hospital admission until date of hospital discharge, assessed up to 10 days after surgery
