The history of the intraperitoneal onlay mesh (IPOM) procedure was first discussed in the early 1990s. While this procedure was highly controversial in the medical community because of increased risks to patients, it was utilized by some physicians. The Atrium C-Qur was intended to be a “tissue separating mesh” for laparoscopic inguinal herniorrhaphy (LIHR). This product was tended for the IPOM implantation technique for LIHR. IPOM involves the placement of mesh directly onto the peritoneum overlapping the hernia defect using laparoscopic cannulas. When implanted with the IPOM technique, the mesh has direct contact with the intestines, which can lead to serious patient complications. These products were promoted to limit or prevent complications known to be associated with implantation adjacent to the intestines. In reality, these products were never proven to limit or prevent complications.

The diagram shows the IPOM implantation position (a), compared to other mesh insertion options. IPOM is the only one where the mesh is in contact with the bowel. IPOM is highly controversial and involved direct contact with the bowel. It requires mesh that in theory prevents adhesion, yet achieves abdominal wall ingrowth. The photo on the right shows the placement in surgery. The mesh is in direct contact with the bowel, which causes potential problems for patients.
