OBJECTIVES: This study aimed to evaluate factors that contribute to the recurrence of external rectal prolapse (ERP) following laparoscopic ventral rectopexy (LVR).
METHODS: All patients who underwent LVR using synthetic meshes between 2011 and 2018 were prospectively included. A standard questionnaire including the Fecal Incontinence Severity Index (FISI) and Constipation Scoring System (CSS) was administered preoperatively and postoperatively. Defecography was performed 6 months postoperatively. Univariate and backward stepwise multivariate Cox analysis was performed to determine the prognostic factors of recurrence.
RESULTS: In total, 132 patients with a median follow-up of 46 months were included. The overall recurrence rate was 6.8% (n = 9), as confirmed by defecography at 6 months in six of the patients. None of the patients developed mesh erosion. FISI and CSS scores were significantly reduced at 3 months and remained significantly reduced for 3 years. Multivariate analyses revealed that the predictors of recurrence included male sex (hazards ratio, 11.3; 95% confidence interval, 3.0-43.0) and age >80 years (hazards ratio, 10.7; 95% confidence interval, 1.3-86.3). Eight patients with recurrence underwent surgery via Delorme's procedure (n = 7) and posterior rectopexy (n = 1). Two patients with new-onset rectoanal intussusception and one with uncorrected sigmoidocoele underwent repeat LVR.
CONCLUSIONS: LVR is effective in treating ERP with low morbidity and low recurrence. Male patients and patients older than 80 years are at increased risk of recurrence. Hence, the LVR technique should be modified or coupled with other perineal procedures when treating ERP, especially in male patients.
