Plain-English summary
A recent study looked at a new type of mesh called SWING-Mesh used in a minimally invasive surgery for inguinal hernias, which are bulges in the groin area. The study involved 294 surgeries in 283 adults, mostly men, with an average age of about 52 years. After three months, none of the patients experienced a recurrence of their hernia, and pain levels significantly decreased over time, with most patients reporting little to no pain. Complications were rare and mostly minor, with only a small percentage needing additional visits or treatments. Overall, the use of SWING-Mesh showed promising early results, but further follow-up will be needed to assess long-term outcomes.
Abstract
<h4>Introduction</h4>Independent postmarket clinical evidence for newly introduced inguinal meshes remains limited. We conducted a multicenter prospective observational study to assess early safety and effectiveness of fixation-free SWING-Mesh in transabdominal preperitoneal (TAPP) / totally extraperitoneal (TEP) repair.<h4>Aim</h4>We aimed to assess early (3-month) safety and effectiveness of fixation-free SWING-Mesh use in TAPP/TEP repair.<h4>Materials and methods</h4>A prospective cohort study was conducted in 20 Polish centers, of which 1 was excluded after central monitoring. Consecutive adults underwent elective TAPP or TEP repair with the unfixed polypropylene SWING-Mesh. Exclusion criteria comprised emergency surgery, bowel resection, contraindications to laparoendoscopic repair, and large direct M3 hernias. Recurrence, complications, unplanned visits / interventions and pain (as per the Visual Analog Scale [VAS]) at discharge, 7-10 days, 30 days, and 3 months postoperatively were recorded. The unit of analysis was the operated groin (case).<h4>Results</h4>We analyzed 294 cases in a total of 283 patients at a mean (SD) age of 51.9 (15.9) years, 84.4% of which were men. TAPP repair was performed in 86.4%, and TEP procedure in 13.6% of the patients. There were no instances of hernia recurrence by 3 months postsurgery. Pain decreased over time (<i>P</i> <0.001): mean (SD) VAS score of 1.8 (1.4) at discharge, 1 (1.2) at 7-10 days, 0.5 (1.1) at 30 days, and 0.5 (1) at 3 months postoperatively. At 3 months after the procedure, 78.5% of the individuals reported a VAS score of 0, and 3.1%, a score equal to or greater than 4. Complication rates were below 10% at each time point and were mostly minor; 6.9% or fewer patients required an unplanned visit or intervention by 3 months postoperatively.<h4>Conclusions</h4>Fixation-free SWING-Mesh use in TAPP/TEP repair was associated with favorable early outcomes. Twelve-month follow-up will report long-term recurrence and chronic pain.
