TissueDB/Tissues/Hernia Sac
The hernia sac is the pouch of peritoneum that protrudes through a fascial defect and may hold herniated abdominal contents. In an indirect inguinal hernia it is the patent processus vaginalis. Hernia repair frees the sac from the cord structures, then reduces, ligates, or excises it. Simulators reproduce it as a thin membranous pouch that tears if handled carelessly. Kept as its own tissue class per Dr Catherine Mohr (24 June 2026).
Materials
| Material | Visual | Tactile | Simulator | Notes |
|---|---|---|---|---|
| Plastic wrap (Press'n Seal), spray glue and Fun-Tak putty | – | – | Laparoscopic Inguinal Hernia Repair Simulator (Kurashima) | Press'n Seal plastic wrap at the base of the hernia defect, held with spray glue and Fun-Tak adherent putty to reproduce the sac's preperitoneal adhesions; careless dissection tears the thin film just as it would tear real peritoneum.[1] |
| Condom | – | – | Laparoscopic Inguinal Hernia Repair Simulator (Hanssen) | A condom glued to the pork chop, its distal portion passing through the punched deep-orifice hole, represents the indirect hernia sac and allows sac dissection, inversion, intra-corporeal ligation and sectioning.[2] |
| Latex glove | – | – | Laparoscopic Inguinal Hernioplasty TAPP 3D Simulator (Pires de Melo Filho) | A latex glove inserted into the spheroidal hernial defect and adhered to the peritoneal overlay represents the hernial sac, enabling hernia identification and reduction (Stage 3).[3] |
