Parietex™ composite open skirt (PCO OS) mesh provides a new level of control during open ventral hernia repair. It is made with the clinically proven Parietex™ composite open skirt (PCO OS) mesh, which combines Parietex™ 3 dimensional mesh with a resorbable collagen film to limit attachments from the viscera. The Open Skirted (OS) design has increased rigidity for easier handling during implantation in open incisional and ventral hernia repair.
The skirted flap on the parietal side of the mesh allows for more easily accessible fixation points in the open approach. The skirt provides an area of fixation protected from the viscera on one side and allows fixation to the abdominal wall without disrupting the collagen film.
All of Covidien's Parietex™ products are created from a macroporous polyester material whose properties invite healthy tissue integration and mesh compliance while reducing encapsulation.1
Features and Benefits
| Feature | Benefit |
|---|---|
| Composite mesh with resorbable collagen film | Proven effective, with more than 10 years of documented success |
| Composite mesh with resorbable collagen film | Lower incidences of visceral attachments in comparative and animal studies3,4 |
| Hydrophilic, macroporous polyester material | Benefit: Stronger incorporation into the abdominal wall in prospective and comparative animal studies4,5 |
| Hydrophilic, macroporous polyester material | Incites excellent fibrous ingrowth and a neoperitoneum versus the inflammatory encapsulation of other meshes6 |
| Hydrophilic, macroporous polyester material | Produces superior cellular proliferation when compared to polypropylene mesh in vitro7 |
| Skirt on Parietal Side | Allows for mechanical fixation, which can reduce procedure time |
| Skirt on Parietal Side | Skirt provides accessible, secure fixation points |

(2005). “Intraperitoneal Treatment of Incisional and Umbilical Hernias Using an Innovative Composite Mesh: Four-year Results of a Prospective Multicenter Clinical Trial.” Hernia: The World Journal of Hernia and Abdominal Wall Surgery, 9, 68-74. At four years, 75.7% of patients in the study were clinically evaluated; one (1.8%) direct recurrence was noted, while six (10%) patients experienced new defects outside the mesh, of which only one required surgery. No other long-term complications were observed. No occlusion, fistulae, or mesh sepsis was reported in the long-term follow-up.

PCO Mesh prevented most adhesions and incited excellent fibrous ingrowth. It also allowed a neoperitoneum to form on the visceral surface of the mesh (p. 632, C2, L36-39). Mean area of adhesions was significantly less for PCO than for either Proceed or PP (Table 1, p. 630). The anti-adhesive collagen visceral layer of PCO Mesh is more effective in preventing adhesions than is the polydioxanone polymer of Proceed mesh (p. 632, C2, L17-19).

Parietex™ Composite Mesh (11.2%), Sepramesh (10.4%), and Tutomesh (4.4%) resulted in decreased surface coverage with adhesions (p. 1323, Table 3). Parietex™ Composite Mesh (49.8%), Prolene (34.7%), Ultrapro (34.7%), and Sepramesh (43.3%) resulted in the most mesh incorporation (p.1323, Table 4).
