Tension-Free Mesh Repair for Incarcerated Groin Hernia: A Comparative Study

Background. Management of emergent groin hernias remains challenging, due to limited consensus in surgical approach and repair options (eg, mesh vs nonmesh, biological mesh, and polypropylene [PP] mesh). Methods. A 5-year retrospective study was conducted on 118 patients who received emergency incarcerated groin hernia repair in Beijing Chaoyang Hospital. The incidence of surgical site infection (SSI), preoperative mortality, sepsis, and ileus was noted. In the follow-up, postoperative foreign body sensation, chronic pain, seroma/hematoma, and recurrence were recorded. The outcomes of different surgical procedures (with mesh/without mesh, biological mesh/PP mesh, transabdominal preperitoneal (TAPP)/Lichtenstein repair) were compared and analyzed. Results. Out of the 118 patients, 14 cases received suture repair (as group A); 104 cases had TAPP repair (n = 44) or Lichtenstein repair (n = 60) with meshes, including 23 cases of biological mesh (as group B); and 81 cases had repair with PP mesh (group C). There were no significant differences between the 3 groups regarding SSI, mortality, sepsis, and ileus. After 20.5 months of follow-up (range from 6 to 65 months), 21.4% of group A developed recurrence, a rate significantly higher than that of group B (4.3%) and group C (0). The incidence of seroma/hematoma in group B was higher than that in group A (7.1%) and group C (7.4%). The results between TAPP group and Lichtenstein group were comparable. Conclusion. Tension-free mesh repair in the treatment of emergency incarcerated groin hernia is safe and effective, which can reduce hernia recurrence without increasing infection risk. The results of biological mesh and PP mesh were comparable.
