    Abstract:
    BACKGROUND: Laparoscopic ventral mesh rectopexy (LVMR) has become a well-established treatment for symptomatic high-grade internal rectal prolapse. The aim of this study was to identify proctographic criteria predictive of a successful outcome. METHODS: One hundred and twenty consecutive patients were evaluated from a prospectively maintained pelvic floor database. Pre- and post-operative functional results were assessed with the Wexner constipation score (WCS) and Fecal Incontinence Severity Index (FISI). Proctogram criteria were analyzed against functional results. These included grade of intussusception, presence of enterocele, rectocele, excessive perineal descent and the orientation of the rectal axis at rest (vertical vs. horizontal). RESULTS: Ninety-one patients completed both pre- and post-operative follow-up questionnaires. Median pre-operative WCS was 14 (range 10-17), and median FISI was 20 (range 0-61), with 28 patients (31%) having a FISI above 30. The presence of an enterocele was associated with more frequent complete resolution of obstructed defecation (70 vs. 52%, p = 0.02) and fecal incontinence symptoms (71 vs. 38%, p = 0.01) after LVMR. Patients with a more horizontal rectum at rest pre-operatively had significantly less resolution of symptoms post-operatively (p = 0.03). CONCLUSIONS: These data show that proctographic findings can help predict functional outcomes after LVMR. Presence of an enterocele and a vertical axis of the rectum at rest may be associated with a better resolution of symptoms.
