title: Polyester composite versus PTFE in laparoscopic ventral hernia repair.
abstract: BACKGROUND
  Both polyester composite (POC) and polytetrafluoroethylene (PTFE) mesh are commonly used for laparoscopic ventral hernia repair. However, sparse information exists comparing perioperative and long-term outcome by mesh repair.
  
  
  METHODS
  A prospective database  was utilized to identify 116 consecutive patients who underwent laparoscopic ventral hernia repair at The Mount Sinai Hospital from 2004-2009. Patients were grouped by type of mesh used, PTFE versus POC, and retrospectively compared. Follow-up at a mean of 12 months was achieved by telephone  interview and office visit.
  
  
  RESULTS
  Of the 116 patients, 66 underwent ventral hernia repair with PTFE and 50 with POC mesh. Patients were well matched by patient demographics. No difference in mean body mass index (BMI) was demonstrated between the PTFE and POC group (31.8 vs.  32.5, respectively; P=NS). Operative time was significantly longer in the PTFE group (136 vs.106 minutes, P<.002). Two perioperative wound infections occurred in the PTFE group and none in the POC group (P NS). No other major complications occurred in the immediate postoperative period  (30 days). At a mean follow-up of 12 months, no significant difference was demonstrated between the PTFE and POC groups in hernia recurrence (3% vs. 2%), wound complications (1% vs. 0%), mesh infection, requiring removal (3% vs. 0%), bowel obstruction (3% vs. 2%), or persistent pain or discomfort  (28% vs. 32%), respectively (P=NS).
  
  
  CONCLUSIONS
  Our study demonstrated no significant association between types of mesh used and postoperative complications. In the 12-month follow-up, no differences were noted in hernia recurrence.
