Does lining polypropylene with polyglactin mesh reduce intraperitoneal adhesions?
Dasika UK; Widmann WD Morristown Memorial Hospital Department of Surgery, New Jersey, USA. A method that appears to reduce the rate of adhesion formation between intraperitoneal viscera and prosthetic mesh is the placement of absorbable mesh between nonabsorbable mesh and intraperitoneal viscera. In this study, polyglactin mesh was compared with nonabsorbable polypropylene mesh (Marlex). Forty-seven Sprague-Dawley rats were divided into four groups: 1) control, 2) polyglactin (Vicryl), 3) polypropylene mesh, and 4) polyglactin-lined polypropylene mesh. All rats that underwent mesh placement had midline laparotomy with anastamosis of mesh to fascial borders. Controls underwent midline laparotomy and closure only. Groups were then studied at 1, 2, and 3 months, respectively, to determine the degree of adhesion formation. Gross inspection was performed by a blinded researcher with numerical rank given based on the number of adhesions observed: 0, none; 1, mild; 2, moderate; and 3, severe.
