PURPOSE: To evaluate the safety and long-term efficacy of stapled transanal rectal resection (STARR) combined with the transverse perineal support (TPS) procedure in the surgical treatment of obstructed defecation syndrome (ODS) associated with internal rectal prolapse and excessive perineal descent (PD).
METHODS: This multicenter observational case-control study involved 7 European centers. During the initial study period, patients underwent STARR alone (group 1), while in the subsequent period, patients received STARR combined with TPS (group 2). All patients were followed clinically at 6, 12, 36, and 60 months, and were offered radiological evaluation between 3 and 5 years postoperatively.
RESULTS: The median postoperative ODS score was similar between groups at 6 months (6 [range, 2-15] vs. 5 [range, 2-13]; P=0.16, Mann-Whitney U-test), but at 36 months, it was significantly lower in group 2 compared to group 1 (11 [range, 5-16] vs. 5 [range, 2-15]; P<0.001, Mann-Whitney U-test), with stable results maintained through 5 years. The success rate followed a similar trend. Postoperative maximum PD during straining remained unchanged in group 1, whereas it significantly decreased compared to preoperative values in group 2.
CONCLUSIONS: The addition of TPS to STARR in the surgical treatment of ODS associated with internal rectal prolapse and excessive PD appears to significantly improve long-term success rates and correct descending perineum.
