Mesh repair under the anterior lamina of the rectus sheath (MUAR) for abdominal incisional hernia.

PURPOSE

Abdominal incisional hernia is a frequent complication of major abdominal operations. Our method of performing mesh repair under the anterior lamina of the rectus sheath (MUAR) involves placing mesh between the dorsal surface of the anterior rectus sheath and the rectus abdominis muscle. We evaluated the short-term and long-term outcomes of our MUAR method.

METHODS

The subjects of this retrospective study were 80 patients with abdominal incisional hernia, who underwent MUAR at our hospital between August, 2009 and September, 2018. We investigated the rate of recurrence and postoperative complications in these patients, who were followed-up postoperatively for at least 18 months. Patients who completed all visits were then followed-up further with questionnaires.

RESULTS

The recurrence rate after MUAR was 0%. Postoperative complications consisted of subcutaneous wound infections in two patients (2.5%), successfully treated with wound cleansing and antibiotics; and subcutaneous hematoma in three patients (3.8%), which was spontaneously absorbed in two patients, and removed in one. There were no other complications, such as seroma, intestinal obstruction, mesh infection and bulging, or prolonged postoperative pain.

CONCLUSION

Mesh repair under the anterior lamina of the rectus sheath is simple and safe with positive short-term and long-term outcomes, suggesting that it is a good option for incisional hernia repair.
