Use of Polytetrafluorethylene Films for Closing of Abdominal Cavity under Conditions of Experimental Peritonitis

Abstract

Four variants of polytetrafluorethylene films differing by size of micropores and manufacturing technology were used for closing of the abdominal cavity under conditions of experimental peritonitis in rats. The results of tensiometry and planimetry helped us to select the optimal variant of polytetrafluorethylene film characterized by sufficient strength, minimum size of micropores, and causing minimum complications.

Infection on the meshes implantation area in the abdominal wall of rats with induced bacterial peritonitis

“…Many authors made experimental studies proving the infiltration of the inflammatory and healing cells with collagen incorporation in surgical meshes 24,[27][28] . Another proved tendency is that monothreads meshes, as the polypropylene ones, with smaller surface of contact permit a minor bacterial adhesive and have a better evolution in clinical infections [29][30] . In practice, there are lots of controversies regarding to the use of meshes in operations with potential infection.…”
