Unlabelled:
Two patients developed seromas overlying Marlex mesh repairs of ventral hernias. After repeated unsuccessful attempts at aspiration of the fluid, each patient underwent formal exploration and excision of the cystic mass to the level of the mesh. Histology showed thick, fibrous, trabeculated cysts. Postoperatively, one patient had prolonged closed suction drainage. In the other, suction drains had scant output, but she developed a recurrence of serous fluid, which resolved with two aspirations.
Conclusions:
1) Mature fibrous cyst is a rare complication of Marlex mesh herniorrhaphy; 2) Chronic seroma collections may be etiologic; 3) Surgical excision and closed suction drainage, rather than simple aspiration, are required for treatment; 4) Prolonged postoperative drainage may be needed to prevent recurrence.
