Summary of MedSun Reports Describing Adverse Events With Surgical Mesh Products for Hernia Repair
MedSun: Newsletter #36, May 2009

Surgical mesh is a polymeric, biologic or metallic screen intended for implant to reinforce soft tissue or bone where weakness exists. It is typically used in surgery for the repair, reconstruction, or substitution of tissue, commonly in hernia repair surgical procedures.

Over the past 2 years, MedSun has received 29 adverse event reports associated with 30 hernia mesh products in 30 patients. The reports were submitted by 20 hospitals between February 2007 and April 2009. The most frequently reported device problems were:

• Mesh explanted due to recall (6 reports)
• Ring breakage (4 reports)
• Mesh tear (4 reports)
• Defective mesh (3 reports)
• Mesh perforation (3 reports)
• Adhesion issue (2 reports)
• Mesh erosion (2 reports)

None of the reports involved a patient death. Common patient injuries listed below were reported in 15 of these 30 patients. Note: more than one patient injury can be assigned to each report.

• Additional surgical procedure required (18 reports)
• Infection (5 reports)
• Abscess (4 reports)
• Pain/soreness (3 reports)
• Inflammation/swelling (3 reports)

All reports had a patient age listed as greater than 21 years. Of the reports that listed patient gender, a total of 20 reports involved female patients and a total of 10 reports involved male patients.

MedSun reports contributed to FDA awareness of these device problems. Complications have been reported with a range of hernia mesh manufacturers, a majority of which are associated with the use of Composix Kugel Hernia Patches manufactured by Davol Incorporated, a subsidiary of C.R. Bard. The Bard Composix Kugel Extra Large Oval Patches were first recalled in December 2005. This Class I recall was expanded two times after the original recall notice, first in March 2006 and again on January 24, 2007, which ultimately recalled all product codes and lot numbers belonging to the Bard Composix Kugel Mesh Patches.

In October 2008, the FDA updated its safety information on hernia mesh repair.

Although the vast majority of reports were related to the recalled meshes, MedSun continues to see reports discussing adverse reactions with the recalled mesh, as well as with other mesh products. FDA continues to analyze and evaluate incoming reports about issues with all hernia mesh products.

Ethicon, Inc. Proceed
Lot: ZLG767
Other: PCDG1
This patient had a hernia repair for three ventral and one umbilical hernia (all three ventral hernias and the umbilical hernia were connected into one large hernia). An approximate 5 X 7 piece of PROCEED mesh was used for this repair. The mesh was placed as an underlay and secured circumferentially with transfascial 0 Prolene sutures. A total of eight sutures were used to secure the PROCEED Mesh. Care was taken to identify the bowel throughout the entire procedure. The physician noted that the patient tolerated the procedure well without complication and was taken to the recovery room in satisfactory condition.

The procedure was done as a same-day-surgery procedure. When at home later that day, the patient developed nausea and vomiting. On the third post-op day, the patient was seen in the Emergency Department with a chief complaint of abdominal pain, nausea/vomiting, and abdominal distention. The patient had not passed any gas or had any bowel movement after the surgery. A CT scan demonstrated that a loop of small bowel incarcerated in the incisional ventral hernia repair. The patient was brought back in for surgery. The physician noted that the etiology of the incarceration was due to the fact that three of the eight transfascial sutures had pulled through the mesh. To remedy the situation, the entire mesh was removed and replaced with a new piece of mesh. The patient tolerated the procedure without complication and was discharged to home five days post-operation.
LifeCell Corporation AlloDerm Regenerative Tissue Matrix
Other: 402025
Patient underwent resection of pilocytic astrocytoma in the posterior fossa. The hospital course was uneventful and the patient was discharged a few days later. The patient returned the next day with fever and pain. The patient was admitted and treated with antibiotics. Cerebrospinal fluid culture revealed an enterobacter aerogenes infection. Nine days later, the patient returned to surgery. There was minimal collection of purulent material in the epidural space; however there was significant collection in the subdural space. The graft to the dura was removed and a new graft from the periosteum was sewn into place.

Patient had dehiscence of ventral herniography with surgical mesh. Patient returned to surgery for repair. Operative Note: Patient noted in Recovery Room (RR) to have disruption to the lower part of ventral abdominal hernia repair. Bard composite graft was attached three fourths of the way around his ventral abdominal wall defect. However, distally in the lower part of the incision, the 1-0 Prolene horizontal mattress sutures were disrupted, as were the staples. The Bard composite graft and the staples achieved very poor mesh adherence to the abdominal wall. Surgeon increased the length of the Bard composite graft by sewing another piece of Bard composite graft to the ventral aspect to the largest of the Bard composite graft that was previously implanted.
Davol Inc. A subdivision of C.R. Bard, Inc. None

Lots: 43GPD434 & 43KOD267
Cat: 10202
Two events involving the same brand (two different lots) of the Kugel hernia mesh. Both lots of the mesh were recalled via a Class I recall in January of this year (2007). The first patient was initially treated for a gunshot wound to the abdomen and developed an incisional hernia, which were repaired with a Kugel patch prior to release of the recall. He recently presented with a recurrent incisional hernia at the 9 and 10 o'clock position. The doctor removed the patch and replaced it with another brand of mesh.

The second patient had a laparoscopic nephrectomy done by a hand-port incisional hernia. The defect was initially repaired with a Kugel mesh device. Approximately a year post-operation, the patient gained 30 pounds and had a reoccurrence of the previous hernia.

Bard Access Systems Composix Kugel Hernia Patch
Lot: 43EQD414
Cat: 10205
Patient had a laparoscopic ventral hernia repair last year. The patient progressed postoperatively as expected, without complication. However, four days postoperative, the patient's condition worsened and the patient had to undergo open surgery where two perforations were noted in the small bowel.

According to the physician, the Composix Mesh was removed and it was noted that the patch had not retained its oval shape. The patch appeared crumpled on both sides and had creases running along the center of the mesh, indicating that the ring had broken.

Model: 10206
Lot: 43APD431
The mesh was placed prior to the manufacturing recall. The patient was brought in for a bowel stricture procedure and, during this surgery, the mesh was identified. Because we were aware that this may have been a recalled mesh product, we called Davol, Inc./C.R. Bard and they confirmed that this was, in fact, a piece of mesh that had been recalled. It was decided that we would remove the mesh, just to be safe.
Bard Access Systems Composix Kugel
Lot: 41ELDP27
Other: REF 0010204
Patient had a bowel obstruction from an incarcerated hernia placed late last year. During that repair the midline incision divided the mesh, which was repaired with nylon. Patient developed a draining wound since that repair.
Ethicon, Inc. ProceedA six month extension was given by the company on outdated mesh. As surgeon was sewing the mesh to the abdomen, the mesh separated. This is not what the mesh is designed to do. The sales representative was notified. The mesh was removed from the patient's abdomen and a different type of (current) mesh was used. All other meshes were pulled from our shelves.

Excerpt from September 2006 Customer Letter:
“Dear Customer,
We are pleased to announce that we have successfully completed stability studies designed to extend the shelf life of PROCEED Surgical Mesh. The results of these studies allow us to expand current expiry dating for an additional six (6) months. This additional data allows for a 12-month shelf-life. An additional 6 months should be added to the date printed on the PROCEED Mesh package for any product currently on the market with an expiration date prior to and including March 2007 (2007 - 3). For example: Current Expiry Date New Expiry Date (October 10, 2006) (April 4, 2007) (February 2, 2007) (August 8, 2007) Any product with an expiry date of April 4, 2007 or LATER reflects the new expiry dating and should be used by the date printed on the package. For example: Current Expiry Date New Expiry Date (April 4, 2007) Date printed on package (Sept 9, 2007) Date printed on package If you have any questions regarding the expiry dating of any PROCEED MESH product, please contact your sales representative.”
