Incisional herniorrhaphy with intraperitoneal composite mesh: a report of 95 cases

Incisional herniorrhaphy remains a formidable challenge to the general surgeon. Recurrence rates after primary repair are reported between 31-54 per cent while tension-free repairs with prosthetic mesh have lowered this rate to 10 per cent. Repairs with composite mesh (polypropylene/ePTFE) have been gaining in popularity due to the ease of mesh placement in the intraperitoneal location. This paper reviews our experience with composite repairs at a teaching community hospital. A retrospective chart review was performed which evaluated all patients undergoing abdominal incisional hernia repairs over a 4(1/2)-year period. The data were analyzed for mortality, recurrence, infection, subsequent bowel obstruction, and fistula formation. Two hundred twenty-one incisional herniorrhaphies were identified in the resident database of which 95 were repaired with Composix mesh (Bard Surgical, Cranston, RI) in the intraperitoneal position. There were two (2%) recurrences and eight (8%) infections. Fistulization to the small bowel from exposed polypropylene occurred in one patient. There were no bowel obstructions. One postoperative death occurred secondary to pulmonary embolus. Mesh removal was required in all infected cases, and there was a high incidence (63%) of methicillin-resistant Staphylococcus aureus (MRSA). Our findings parallel the low recurrence rate following prosthetic repair. We have reported a higher than expected infection rate particularly with MRSA. Although repairs with Composix mesh are highly successful in regard to recurrence, the high infection rate and resulting morbidity needs to be further evaluated.
