AimThis study examines the behavior of the adhesive Parietene Progrip® mesh by Covidien in open posterior preperitoneal inguinal hernia repair using a personally modified Nyhus technique. Material and methodIn a prospective, single center, descriptive and observational analytical study, we consecutively examined all patients undergoing elective or emergency surgery for a primary or recurrent inguinal hernia over the period between February 2009 and December 2012. Postoperative pain was assessed using the visual (color) and analogical (millimeters) scale. Complications and pain were determined upon hospital discharge and at weeks 1 and 2; one, 3 and 6 months and one year after surgery. Pain was also assessed daily during the first postoperative week. ResultsThree hundred fifty-five inguinal hernia repair surgeries were performed in 331 patients of mean age 44 years (14-87 years). Surgeries were of primary repair, scheduled repair, recurrent and emergency kind (89, 93.5, 11 and 6.5%, respectively). BMIs were 27kg/m2 in 28% of the patients, and>35kg/m2 in 7%. Mean surgery length was: 13.7±3.3min (4–93min) and mean hospital stay was 15±3h (12-20h). Complications were: seroma (6%), urinary retention (2%), hematoma (2.4%), and surgical wound infection (0.3%). No patient reported persistent groin pain. As of late morbidities, one patient suffered mild testicular pain following bilateral surgery during the first postoperative month and there was one hernia recurrence (0.3%). The mean pain score for the first 3 postoperative days was 19.7±4.4mm. Follow-up (median: 28 months) was complete in 315 patients (95.4%). There were no reports of chronic inguinal pain. ConclusionsSurgical access and mesh placement has, based upon our experience, proved easy, rapid and effective. Patients suffered no chronic pain and there was only one hernia recurrence.
