Article: Laparoscopic herniorrhaphy with porcine small intestinal submucosa: a preliminary study

Introduction: Using mesh or a synthetic prosthesis during the laparoscopic repair of inguinal hernias has been demonstrated to be safe and effective. A new material, porcine small intestinal submucosa (SIS mesh), has been successfully used in canine and rodent animal models with excellent results. This mesh is degradable and resorbable with a marked decrease in the possibility of becoming infected. However, the amount of fibroblast ingrowth is equal to that with polypropylene mesh.

Methods: A comparison was made between this new SIS mesh to repair 15 inguinal hernias in 12 patients and polypropylene mesh used in 12 similar patients. A preperitoneal approach with balloon dissection was used in all patients.

Results: Demographics were similar in both groups. The results were excellent and compared equally. Complications (seroma, discomfort) were minimal in both groups and were similar.

Conclusions: Porcine small intestinal submucosa, SIS mesh, can be used for laparoscopic repair of inguinal hernias. Long-term follow-up will be necessary to confirm these preliminary results.
