Knitted polypropylene (Marlex) mesh in the repair of incisional hernias
Abstract:
In 50 consecutive patients, large incisional hernias or those difficult to manage were repaired by suture imbrication of the hernial sac and extrafascial onlay fixation of Marlex mesh. Seromas developed in three and wound infection in two. The use of closed suction drains for all patients and antibiotic prophylaxis before and after operation for patients with antecedent wound infections may prevent these complications. In the follow-up period (mean of 2.6 years), lateral recurrence of the hernias occurred in three patients, but there has been no recurrence in the last 2 years. The method of repair is simple and effective.
Insights
This study shows that repairing large incisional hernias with Marlex mesh is effective. While some complications like seromas and infections occurred, they can be prevented with drains and antibiotics, leading to good long-term results.
Area of Science:
- General Surgery
- Hernia Repair Techniques
Background:
- Large incisional hernias pose significant management challenges.
- Surgical repair is often complex and associated with recurrence.
Purpose of the Study:
- To evaluate the efficacy and safety of a specific surgical technique for large or complex incisional hernias.
- To assess complication rates and long-term recurrence following this repair method.
Main Methods:
- Suture imbrication of the hernial sac combined with extrafascial onlay Marlex mesh fixation.
- Involved 50 consecutive patients undergoing hernia repair.
- Utilized closed suction drains and antibiotic prophylaxis in select cases.
Main Results:
- Low complication rates: 3 seromas and 2 wound infections observed.
- Effective hernia repair with a mean follow-up of 2.6 years.
- Three lateral recurrences occurred initially, with no recurrences in the final 2 years of follow-up.
Conclusions:
- The described surgical method is simple and effective for large incisional hernias.
- Prophylactic measures like drains and antibiotics can mitigate postoperative complications.
- The technique demonstrates durable results with minimal long-term recurrence.
