[Umbilical hernia in adults: laparoscopic approach with prolene mesh--is it a safe procedure?]

The laparoscopic approach for umbilical hernia is more and more used, but few results are reported. The aim is to evaluate the efficacy and safety of using the Prolene mesh placed laparoscopically in umbilical hernia treatment.

Between 2004-2006, 21 patients with umbilical hernia, aged of 34 to 77 years, were submitted to intraperitoneal application of a Prolene mesh to cover the umbilical ring. The mesh was sewed by Protack staples or transfascial stitches. Before deflating the patients, the greater omentum was interposed between the mesh and the bowel. It is notice that 8 patients were obese, 6 patients had omental or bowel adhesions to the peritoneal sac and 5 patients had ascites due to liver cirrhosis. The patients were discharged 24 to 48 hours after the operation and followed up for 6 to 12 months.

All patients were alive at the end of follow-up, without hernia recurrence or complications due to the Prolene mesh in the abdominal cavity. In 3 patients we registered subcutaneous seromas for 1 to 3 weeks (imposing evacuation by punction) and 5 patients kept a mildly deformed umbilical scar after the cure of large hernias.

In the literature are mentioned the techniques using composite or two-layers meshes. Prolene meshes are not agreed by some authors, for the supposed risk of bowel lesions. In our trial were no such complications.

Laparoscopic repair using Prolene intraperitoneal mesh in umbilical hernia is a safe, efficient and rapid method, avoiding infections complications in obese or cirrhotic patients.
