Surgical physiology of XXXX --a study of 200 cases.

@entity1 @entity169 @entity547
BACKGROUND: Current @entity169 are generally based on anatomical considerations. Failures of such operations are due to lack of consideration of physiological aspects. Many @entity1 with @entity169 are cured as a result of current techniques of operation, though factors that are said to prevent @entity547 formation are not restored. Therefore, the surgical physiology of inguinal canal needs to be reconsidered. METHODS: A retrospective study is describer of 200 @entity1 operated on for @entity169 under local anaesthesia by the author's technique of @entity169 . RESULTS: The posterior wall of the inguinal canal was weak and without dynamic movement in all @entity1 . Strong aponeurotic extensions were absent in the posterior wall. The muscle arch movement was lost or diminished in all @entity1 . The movement of the muscle arch improved after it was sutured to the upper border of a strip of the external oblique aponeurosis (EOA). The newly formed posterior wall was kept physiologically dynamic by the additional muscle strength provided by external oblique muscle to the weakened muscles of the muscle arch. CONCLUSIONS: A physiologically dynamic and strong posterior inguinal wall, and the shielding and compression action of the muscles and aponeuroses around the inguinal canal are important factors that prevent @entity547 formation or @entity547 recurrence after repair. In addition, the squeezing and plugging action of the cremasteric muscle and binding effect of the strong cremasteric fascia, also play an important role in the prevention of @entity547 .
