IntroductionThe concomitant presence of a rectocele with obstructive defecation syndrome (ODS) is highly probable. The purpose of this study was to evaluate the effectiveness of native tissue vaginal rectocele repair (VRR) and laparoscopic ventral mesh rectopexy (LVMR) in terms of functional outcome via the medium to long-term ODS score evaluation. MaterialThis was a retrospective cohort study. We identified 30 patients having undergone LVMR for rectocele with defecatory symptoms between January 2015 and December 2021, matched with the same number of patients treated by VRR for the same indication and in the same period. The hypothesis was that both procedures were susceptible to lead to a favorable functional outcome. The main endpoint was ODS score at follow-up. Multivariate analysis was used to assess relationship between ODS score and type of surgery. ResultsPatients’ demographics were similar in both groups. However, the preoperative ODS score was significantly higher in the LVMR group (P<0.01). Furthermore, the use of preoperative imaging investigations and diagnosis of an associated rectal intussusception were more frequent in the LVMR group. The mean ODS scores at follow-up (median follow-up 5years) were comparable in the two groups (6.2 for LVMR and 4.43 for VRR). These scores were significantly reduced compared to preoperative values in both groups (P<0.0001). ConclusionsThere was a significant reduction in ODS scores on medium/long-term follow-up with both surgical techniques. A larger study utilizing randomized comparison of both procedures is needed to confirm our findings. Level of evidence4.
