Background Mesh reconstruction has been proved to be an effective method in incisional hia repairment. This study was designed to evaluate the effect of reconstructing the pelvic floor with the high-inlay expanded polytetrafluoroethylene (ePTFE) GORE-TEX Dual Mesh (WLGore And Associates, Flagstuff, USA) in abdominoperineal resection.Methods Sixty patients who underwent abdominoperineal resection for rectal cancer were assigned to 2 groups. The pelvic peritoneum was closed by routine sutures in group 1 and reconstructed with ePTFE in group 2. Postoperative complications and related items were evaluated and the patients were followed up.Results Time of confining to bed, bowel function recovery, fasting, and detaining drainage were significantly different between two groups (P <0.05). In group 1, three patients developed bowel obstruction (10%), while no bowel obstruction was observed in group 2.Conclusion Reconstruction of the pelvic floor using ePTFE results in quicker postoperative recovery and could decrease the risk of postoperative intestinal obstruction.
