Hernia mesh adhesions are scar tissue resulting from hernia mesh operations and the healing process. Following hernia repair surgeries, adhesions may form in the abdomen or peritoneum. The mesh repairs usually heal quickly but when adhesions form, organs connected by the scar tissue may not function properly.
The popularity of hernia mesh operations has led to increasing concern regarding mesh-related adhesions. Adhesions result from the fibrin exudates that follow any kind of trauma.
These exudates form temporary adhesions until the fibrinolytic system absorbs the fibrin. Absorption is delayed in the presence of inflammation or foreign bodies such as mesh devices. In these situations, they develop into tissue adhesions.
All mesh implants produce adhesions, though their extent varies. Abdominal adhesions are a common complication, occurring in a majority of people who undergo abdominal or pelvic surgery. Adhesions cause the majority of small bowel obstructions in adults, and are believed to contribute to the development of chronic pelvic pain.
X-rays do not reveal potential mesh issues or diagnose the presence of adhesions. An additional surgery is usually needed to diagnose or treat hernia mesh adhesions. However, revision surgeries carry risks and can lead to further health problems, including infection, bowel blockage, bowel perforation and chronic pain.
Adhesions may begin forming long before they are noticed by patients or doctors. Depending on the location, adhesions from defective hernia mesh devices may cause pain and affect the bowel in different ways. Even removing a defective hernia mesh product may not completely solve all health issues.
Symptoms of adhesion and hernia mesh injury may include:
• Severe abdominal pain or cramping
• Vomiting
• Bloating
• Loud bowel sounds
• Swelling of the abdomen
• Constipation
