Purpose: The choice of surgical procedure for rectal prolapse (RP) is challenging because of the high recurrence and morbidity rates. We aimed to clarify whether laparoscopic suture rectopexy (lap-rectopexy) is suitable for Japanese patients with recurrent RP.
Methods: We retrospectively evaluated 77 recurrent RP patients who had been treated on average 1.5 times between June 2008 and April 2016. Forty-one patients underwent lap-rectopexy and 36 underwent perineal procedures. We compared surgical outcomes and recurrence rate following surgery between the two groups. The multivariable logistic regression analysis was performed to determine risk factors of recurrent RP.
Results: In patients' characteristics, significant differences were observed in the type of anesthesia (p < 0.01) and length of recurrent RP (p = 0.030). The mean operative time was significantly longer in the lap-rectopexy group (p < 0.001). Blood loss, length of hospitalization, and postoperative complications were similar. The recurrence rate was significantly lower in the lap-rectopexy group (17.1% vs. 38.9%, p = 0.032). Multivariate analysis showed that only the laparoscopic approach was significantly associated with a low recurrence following surgery (odds ratio 0.273, 95% CI - 2.568 to - 0.032).
Conclusion: Lap-rectopexy is recommended for recurrent RP because its low recurrence rate and safety profile are similar to those of perineal procedures.
