Introduction:
The Polysoft patch was conceived to associate the advantages of placement of the patch in the preperitoneal space (PPS) and easiness of the inguinal incision. The aim of this study was to evaluate prospectively the feasibility and postoperative outcome of this method.
Methods:
Two hundred Polysoft repairs were performed in 191 consecutive patients with Nyhus types III and IV hernias. The anesthesia was spinal in 146 patients (76.4%), local in 36 (18.8%) and general in 9 (4.7%). The patch was placed in the PPS through the hernial orifice in the fascia in direct hernias and through the internal orifice in indirect ones. The technical points and postoperative course data were prospectively recorded and postoperative pain was assessed daily by visual analogue scale (VAS) in 25 patients.
Results:
The method was achieved in all the cases. The type of the hernias was as follows: 59 direct, 129 indirect (including 28 pantaloon and 16 sliding), 3 inguino-femoral and 9 recurrent. The size of the patch used was medium in 152 cases (76%) and large in 48 (24%). The large patch was used more in pantaloon, sliding and inguino-femoral hernias. In direct hernias the patch was not split; in indirect hernias the patch was split (so the wings recreate a new internal orifice around the spermatic cord) in 79 cases (61.2%) and not split (with the cord parietalized) in 50 cases (38.8%). The length of operation, postoperative hospital stay, return to daily activity, to work and analgesics consumption were [median +/- SD (extremes)]: 35 min +/- 9.1 (20-60), 1 day +/- 0.4 (0-5), 3 days +/- 1.8 (0-8), 15 days +/- 9.7 (1-30) and 3 days +/- 2.3 (0-10), respectively. The median number of analgesics units was 8 +/- 5.9 (0-32). The values of pain assessed daily by VAS (on 100) varied from 20.4 +/- 19.7 (0-60) at day 0, 25.0 +/- 24.5 (0-80) at day 1 to 7.5 +/- 13.7 (0-50) at day 7; the mean value for the week was 16.7 +/- 16.7 (0-57). There were 14 (7%) benign postoperative complications.
Conclusion:
This study permitted the definition of some technical points and showed that the Polysoft patch can be used for all types of hernias with a weak posterior wall, including complex cases (big scrotal, pantaloon, sliding and recurrent), with a low risk of postoperative complications, a low level of postoperative pain and a short recovery time.
