[The use of an underlay polypropylene mesh in complicated incisional hernias: sucessful French surgical technique].
BACKGROUND
Incisional hernia repair with conventional techniques is associated with high recurrence rates of 30-50%. Surgical repair using different prosthetic biomaterials is becoming increasingly popular. On the basis of the favourable results by French surgeons, the results of underlay prosthetic mesh repair using polypropylene mesh in complicated and recurrent incisional hernias have been studied.


METHODS
After preparation and excision of the entire hernia sac, the peritoneum and posterior rectus sheath are closed with a continuous looped polyglyconate suture. The prosthesis used for the midline hernias is positioned on the posterior rectus sheath and extends far beyond the borders of the myoaponeurotic defect. The prosthesis for lumbar and subcostal hernias is placed in a prepared space between the transverse and oblique muscles. Intraperitoneal placement of the mesh must be avoided. Between January 1997 and September 1998 a total of 57 incisional hernia repair (25 primary hernias, 32 recurrent hernias) have been performed using this technique (28 women, 29 men, mean age 56+/-13 years).


RESULTS
Local complications occurred in 6 patients (11%). One patient suddenly died on the 3rd postoperative day from severe pulmonary embolism (mortality 1,7%). Thirthy-seven patients with a minimum follow-up of 6 months were reexamined clinically (follow up time 6-33 months). Till now one recurrent hernia has been observed. There were only minor complaints like  a feeling of tension  in the abdominal wall (n = 3) and slight pain under physical stress (n = 9).


CONCLUSIONS
The aforementioned technique of underlay prosthetic repair allows an anatomical and consolidated reconstruction of the damaged abdominal wall with excellent results and low complication rates especially in high risk patients and complicated hernias.
