Abstract

Background: The repair of ventral hernias by intra-peritoneal patch (IPOM) involves a risk of pain due to stapling as well as intestinal adhesions. Extraperitoneal placement of the patch without fixation can prevent these drawbacks. Techniques of endoscopic preperitoneal repair were previously described by others. The aim of this article is to describe our technique and to evaluate the feasibility and short-term results.

Methods: The totally endoscopic technique consists of dividing the median aponeurotic structures, while preserving the proper linea alba, to create a unique retro-muscular space, in which the patch is deployed without any fixation. Hundred twelve consecutive patients were operated on for ventral hernias (82 umbilical, 20 epigastric, 10 combined). Perioperative data including duration of operation, technical problems, conversions and complications, as well as postoperative pain, time to resume daily activities and time off work were prospectively assessed.

Results: 98 (87.5%) patients were operated in ambulatory surgery, and 14 (12.5%) in overnight stay. The mean sizes of the hernia and the patch were 9 (1-50) cm2 and 225 (50-500) cm2, respectively. The mean operation duration was 75 (30-270) min. The peritoneum was opened in 43 (38.4%) cases and closed by suture in 41 instances. There were 5 (4.5%) conversions to IPOM and 4 (3.6%) complications (1 seroma, 1 urine retention, 1 transitory ileus, and 1 intestinal obstruction) which were reoperated. The mean VAS value of postoperative pain was 2.45 (0-8), pain was scored 0 by 17 (15%) patients. The mean times to resume daily activity and work were 4 (1-15) days and 11.5 (1-30) days, respectively.

Conclusion: Our results suggest that VTEP is safely feasible by surgeons skilled in laparoscopy, and might contribute to minimize pain, though this must be established by comparative studies.
