The evolution of transanal surgery for obstructed defecation syndrome: Mid-term results from a randomized study comparing double TST 36 HV and Contour TRANSTAR staplers.
A randomized study was carried out to compare the mid-term outcome of transanal rectal resection with the CCS-30 TRANSTAR and two TST36 staplers in patients with obstructed defecation syndrome. After selection, patients were randomly assigned to 2 groups:104 underwent a TRANSTAR operation and 104 a transanal rectal resection with two TST36 staplers. Patients were followed up with clinical examination, and defecography. Cumulative complication rate was significantly higher in TRANSTAR operation (P = 0.019). All symptoms and defecographic parameters significantly improved (P < 0.001), without differences. Costs were significantly lower with double TST (P = 0.035). Recurrence rates were 6.2% in TRANSTAR group and 11.4% with double TST (P = 0.206). Two circular TST 36 staplers consent to obtain the same clinical and functional results than the CCS-30, with significantly lower complication rate and costs.
