Comparison of the plasma and hernia sac tissue copper levels in direct and indirect inguinal hernia patients.
Although the inguinal hernia is among the most commonly encountered and well-described health problems all over the world, the etiology is still controversial. The aim of this study was to compare the plasma and hernia sac tissue copper levels in direct and indirect inguinal hernia patients. Plasma and hernia sac tissue copper levels obtained from patients operated under spinal anesthesia with primary direct (group I, n = 55, 45 male, mean age = 45.68 yr) and indirect (group II, n = 55, 40 male, mean age = 38.57 yr) hernias were detected by atomic absorption spectrophotometer. Significantly lower plasma and hernia sac tissue copper levels were detected in group I in comparison to group II (p < 0.001). Both plasma and hernia sac tissue copper levels were significantly lower in males when we compare the patients according to their sex characteristics, including both direct and indirect hernia groups (p < 0.05 and p < 0.01, respectively). Age was not a significant factor. The plasma and hernia sac tissue copper levels were significantly lower in direct hernia patients in comparison to indirect hernia patients. Copper is a cofactor of lysyl oxidase, an important enzyme in collagen tissue metabolism, so there might be a defect in the collagen synthesis of direct hernia patients because of the decreased activity of the lysyl oxidase. Further investigations are necessary to clarify this concept.
