Incisional hernioplasty with Mersilene

Area of Science:

• Surgical Innovation
• Biomaterials in Medicine
• Abdominal Wall Reconstruction

Background:

• Large incisional abdominal hernias (myoaponeurotic defects >10 cm) pose significant surgical challenges.
• Recurrence after hernia repair remains a common complication, necessitating robust techniques.
• Existing methods may not adequately address the mechanical forces and tissue integration required for large defect repair.

Purpose of the Study:

• To evaluate the efficacy of a novel incisional hernioplasty technique for large incisional abdominal hernias.
• To assess the role of Mersilene (polyester fiber) prosthesis in preventing hernia recurrence.
• To elucidate the mechanisms by which the prosthesis achieves stable fixation and abdominal wall reinforcement.

Main Methods:

• Thirty patients with large incisional abdominal hernias underwent repair using a Mersilene prosthesis.
• The prosthesis was implanted between the abdominal muscles and peritoneum, extending beyond the defect margins.
• Fixation relied on intra-abdominal pressure and subsequent fibroblastic ingrowth.

Main Results:

• All thirty cases of large incisional hernias were successfully repaired.
• The Mersilene prosthesis demonstrated effective adherence to the visceral sac, preventing eventration.
• Solid fixation was achieved through intra-abdominal pressure and fibrous tissue integration.

Conclusions:

• Incisional hernioplasty with Mersilene prosthesis is a highly effective treatment for large incisional abdominal hernias.
• The technique leverages intra-abdominal pressure and tissue ingrowth for durable repair.
• Mersilene's properties (suppleness, texture, reactivity) are crucial for successful prosthesis integration and hernia prevention.
