People suffering from hernia may ask themselves if Kugel mesh materials are highly efficient and they can contribute to the definitive cure of this disease. The answer can be positive as long as the surgeon knows the advantages and the disadvantages of their use and if he or she can spot the materialistic offers of companies that are too willing to promote their products in the detriment of their quality. Kugel mesh patches are reliable, but there can also be defective hernia patch side effects in the surgery of inguinal femoral hernias. Some scientists classify defective hernia side effects in obvious, disputable, and possible.

A study has been conducted in order to evaluate the extent of defective hernia patch side effects in the case of patients suffering from complex hernia. From May 1999 to June 2004 in a hospital in the USA 7 patients suffering from severe hernia complications were hospitalized and operated. These defective hernia patch side effects were consequences of the prosthetic or non-prosthetic treatment of complex inguinal hernias or of hernias whose risk of recurrence was high. These patients belong to a group of 272 people suffering from complex hernia, from January 1995 - December 2004. The patients whose defective hernia patch side effects were severe were 2.57% of the total number of hernia sick people.

There were more defective hernia patch side effects developed because of the surgical treatment. Firstly, there was a severe infection of the prosthetic material. Secondly, there was a chronic debilitating inguinal pain. On a visual analogical scale, the patients associated the pain intensity with 4 if they were still and 7 if they made an effort.

The clinical expertise proved that the right inguinal area had a normal aspect, with supple post operatory scar. On palpating, a painful area was spotted in the medial region of the inguinal channel. If the inguinal area of the patient had been palpated while he or she was lying down, the pain might become more intense. Radiography of the spinal column had been taken, without noticing changes of the lumbar column.

A neurological exam had not led to specific lesions in that area. The peripheral obstruction with Xilinx 1% of the iliac hypo gastric nerves and iliac inguinal ones had not improved the clinical symptoms. The patient was offered specific medication for 5 days when he was taken a tomography of the inguinal area. It highlighted the rough contraction of the prosthesis like a cap that caused mechanical pressure on the nerves in the inguinal area.

The conclusion of this study is that defective hernia patch side effects can be the infection of the prosthesis, the transmigration through a hollow viscera (esophagus, thin or thick intestine, urinary bladder). Another side effect is the adherence to vascular structures that can be worn out through external compression, or neuralgias. Furthermore, disputable defective hernia patch side effects are related to the contraction of the prosthesis, to its structural alterations and the immobility of the abdominal wall. Finally, a probable side effect is the carcinogenesis.
