Delayed primary closure of contaminated abdominal wall defects with non-crosslinked porcine acellular dermal matrix compared with conventional staged repair: a retrospective study.

Introduction: Synthetic mesh has been used traditionally to repair abdominal wall defects, but its use is limited in the case of bacterial contamination. New biological materials are now being used successfully for delayed primary closure of contaminated abdominal wall defects. The costs of biological materials may prevent surgeons from using them.

Chronic pain after laparoscopic transabdominal preperitoneal hernia repair: a randomized comparison of light and extralight titanized polypropylene mesh.

Background: The aim of this prospective, randomized, single-blinded clinical trial was to compare the incidence of chronic pain after laparoscopic transabdominal preperitoneal hernia repair (TAPP) using a 35-g/m2 titanized polypropylene mesh and a 16-g/m2 titanized polypropylene mesh. The reported incidence of chronic pain in patients who underwent laparoscopic hernia repair is a serious problem. The techniques of dissection, mesh fixation, and the mesh material used have all been identified as being part of the problem.

Invisible scar endoscopic thyroidectomy by the dorsal approach: experimental development of a new technique with human cadavers and preliminary clinical results.

Background: A unilateral gasless single-surgeon videoendoscopic thyroidectomy procedure using a dorsal cephalic approach from the scalp with the option for a bilateral approach was developed with human cadavers and a porcine model for access training. The final preclinical trials and the first three clinical cases are described in detail.

Methods: Preclinical evaluation and training for the procedure were conducted with fresh human cadavers.
