Correct Answer » D
Explanation
|
|
When a mesh is placed intraperitoneally, it comes into direct contact with the bowel and other viscera. Ordinary polypropylene meshes may cause:
- Dense adhesions
- Bowel erosion
- Enterocutaneous fistula formation
- Intestinal obstruction
Therefore, tissue-separating (composite) meshes are recommended for intraperitoneal placement.
Characteristics of Tissue-Separating Meshes
- One surface promotes incorporation into the abdominal wall.
- The visceral surface has an anti-adhesive barrier that prevents bowel adhesions.
- Designed specifically for Intraperitoneal Onlay Mesh (IPOM) repair.
Why Other Options Are Incorrect
- A. Light-weight porous meshes – suitable for many hernia repairs but not ideal for direct bowel contact.
- B. Heavy-weight porous meshes – associated with more fibrosis and discomfort; not preferred intraperitoneally.
- C. Absorbable meshes – provide temporary support and are not routinely used for definitive hernia repair.
