Abstract
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.
