- Purpose
Laparoscopic ventral mesh rectopexy (LVMR) is effective for the treatment of rectal prolapse. However, descending perineal syndrome may impair the outcomes of LVMR. The aim of this study was to assess the safety and functional outcomes of LVMR performed with and without transverse perineal support (TPS).
Methods
This was a retrospective study of 143 consecutive female patients treated with LVMR with or without TPS between 2018 and 2022. Patients with rectal prolapse and perineal descent who underwent surgery were included. Obstructed defecation syndrome and fecal incontinence were evaluated using the Cleveland Constipation Score (Wexner score) and St. Mark’s Incontinence Score, respectively. Perineal descent was defined using defecography. Biological meshes were utilized in all cases.
Results
No significant differences were recorded between with- and without-TPS groups at baseline. TPS was performed in 110 patients (76.9%). Surgical morbidity was higher in the with-TPS group (12.7% vs. 0%, P=0.047), primarily due to seroma formation. Almost all complications were mild (Clavien-Dindo grades I–II). In both groups, digital aid for defecation (P<0.001), prolonged straining (P=0.004), and hematochezia (P<0.001) nearly disappeared postoperatively, though constipation and laxative/enema use persisted in 22.4%. Fecal incontinence significantly decreased from 43.4% to 11.2% (P<0.001). TPS appears to have a potentially favorable effect in reducing the constipation score. Both constipation and incontinence scores remained low up to 24 months after surgery. Operative time was significantly longer in the LVMR with-TPS group (P<0.001).
Conclusion
LVMR with TPS appears safe and feasible. TPS may provide better surgical outcomes compared to LVMR alone for patients with symptomatic rectoceles and descending perineum syndrome.
