Abstract

Background and objectives: Although several large studies regarding patients undergoing minimally invasive repair of incisional hernia are currently available, the results are not particularly reliable as they are based on heterogeneous groups, different surgical techniques, different mesh types, or with a too short follow period.

Methods: We conducted a retrospective observational trial, collecting data from patients who underwent laparoscopic repair of a primary abdominal wall or an incisional hernia using the laparoscopic Intraperitoneal Onlay Mesh technique and a single mesh type, i.e., a composite polyester mesh with a hydrophilic film (Parietex CompositeTM mesh - Medtronic, Minneapolis, MN - USA). All patients signed an informed consent.

Results: One thousand seven hundred seventy-seven patients were enrolled. The median surgery time was 50 minutes and the median length of hospital stay was 2 days. Intraoperative complications occurred in 12 patients (0.7%), while early postoperative surgical complications occurred in 115 (6.5%); during follow-up, bulging mesh was diagnosed in 4.5% of cases and hernia recurred in 4.3% of patients. An overlap equal or greater than 4 cm resulted as a significant protective factor, while the use of absorbable fixing devices was a risk factor for recurrence (odds ration: 9.06, p < 0.001, 95% confidence interval: 4.19 - 19.57).

Conclusions: Minimally invasive treatment of primary and postincisional abdominal wall hernias is a safe, effective, and reproducible procedure. An overlap equal or greater than 4 cm, the use of nonabsorbable fixing devices and a postoperative care and follow-up regime are crucial in order to obtain good results and low recurrence rates.
