Female patients presenting with obstructed defecation syndrome due to anterior rectocele will be screened according to inclusion and exclusion criteria. Eligible patients will undergo clinical assessment and appropriate investigations including defecography. After informed consent, patients will be randomized into two groups: Stapled Transanal rectal resection or Stapled Transvaginal rectal resection. Improvement in obstructed defecation symptoms and postoperative complications will be compared between the two groups.
This is a randomized controlled trial aims to compare the clinical outcomes of Stapled Transanal versus Stapled Transvaginal rectal resection in female patients with obstructed defecation syndrome (ODS) caused by anterior rectocele.
Female patients presenting to the outpatient colorectal clinic with symptoms of obstructed defecation syndrome will be screened for eligibility according to predefined inclusion and exclusion criteria. All eligible patients will receive a detailed explanation of the study objectives, procedures, potential benefits, and risks. Written informed consent will be obtained prior to enrollment.
A comprehensive preoperative evaluation will be performed for all participants, including detailed medical history, physical and anorectal examination, and appropriate investigations including defecography to confirm the diagnosis and assess the severity of rectocele.
Enrolled patients will be randomly assigned in a 1:1 ratio into one of two intervention groups. Group A will undergo stapled Transanal rectal resection, while Group B will undergo stapled transvaginal rectal resection. All surgical procedures will be performed by experienced colorectal surgeons.
Primary outcome measures will include improvement in obstructed defecation symptoms as assessed by Cleveland Clinic Constipation (CCC) score. Secondary outcomes will include length of hospital stay, operative time, postoperative pain score, postoperative continence state, Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) and postoperative complications.

| Stapled Transanal Rectal Resection | Procedure | Patients were placed in the lithotomy position. Using the trans-anal approach, rectocele was done using PPH circular staplers. A circular anal dilator (CAD) was inserted into the anus and sutured into position. Three full-thickness prolene 2/0 sutures were positioned at the anterior, left anterior lateral, and right anterior lateral locations, approximately 4 cm above the dentate line. At the posterior aspect, a tongue depressor was placed into the CAD groove to protect the posterior rectal wall. After insertion of the Procedure for Prolapse and Hemorrhoids stapler (PPH stapler) into the rectum with its head open past the proximal suture, PPH stapler was progressively closed. Per vaginal examination was done To make sure the stapler did not include the vagina. The stapler was then fired to complete the anterior rectal resection. |

| Improvement in obstructed defecation symptoms in both groups using Cleveland Clinic Constipation (CCC) score | Compare Improvement in obstructed defecation symptoms in both groups using Cleveland Clinic Constipation (CCC) score. CCC score ranges from 0 to 30. Higher scores indicate a worse outcome (more severe obstructed defecation symptoms ) | Up to 6 months postoperatively |

| Stapled Transvaginal Rectal Resection | Procedure | The patient in the lithotomy position. Anal dilatation was performed. A transverse incision was made in the mucocutaneous border of the vaginal introitus; the posterior vaginal wall was dissected and separated from the anterior rectal wall up to the posterior fornix. Dissection was extended laterally to the maximum length of the rectocele. Two Babcock clamps were applied longitudinally to the rectocele, and the stapler was fired to divide the rectocele. Partial thickness stitches were applied over the staple line using vicryl 2/0 suture to reinforce the staple line. |
