[Total intradermal suture techniques].

Two kind of total intradermal suture techniques are described in the present report. These procedures allow an effective reduction of post-operative pain of surgical wound, prevent infections, cut down tissutal trauma, achieve better aesthetic results, making easier postoperative patient's management. From January 2001 to December 2007, 1,427 patients underwent surgical treatment and the wounds have been sewn with self-locking knots or intradermal skin closure with introflecting knots.

Histological findings of the internal inguinal ring in patients having indirect inguinal hernia.

Background: Aiming to deepen the understanding of the factors involved in the genesis of groin hernia, this study is focused on identifying the histological changes within the muscle fibers of the internal inguinal ring in patients having indirect inguinal hernia.

Methods: In eight patients with primary or recurrent bilateral indirect inguinal hernia who underwent a Stoppa open posterior inguinal hernia repair, a tissue specimen from the edge of the internal inguinal ring was biopsied and histologically examined.

Results: In all of the tissue samples, remarkable degenerative changes such as fibrohyaline degeneration of the muscle fibers, vascular congestion, and phlogistic infiltration through lymphohistiocytary elements was constantly detected.

Sphincter-like motion following mechanical dilation of the internal inguinal ring during indirect inguinal hernia procedure.

Introduction: Even today, there is still great speculation as to the underlying pathogenesis of inguinal hernia. As a result, it could be extrapolated that the vast majority of repairs are based upon conjecture. Most current repairs are founded upon the principle of "closing the defect" in the anatomy, either by suturing closed under tension, covering with a mesh or obliterating the defect with a plug.
