[Structure of the venous wall of the pampiniform plexus in idiopathic varicocele].

The Authors discuss about some histologic patterns observed in 100 pampiniform plexus specimens of patients who underwent direct scrotal surgery for idiopathic varicocele. Tunica media was involved in all of 81 specimens in which Authors observed a vascular wall thickening. Out of these, localized hypertrophic phenomena, leading to segmental vascular obliteration, prevailed (74%) on widespread forms (26%). In advanced focal localizations subintimal fibrous pads were demonstrated. In 96% of cases hypertrophy affected the muscular layer too, respectively in focal (41%) and diffuse (59%) way. In 85% of cases fragmentation of lamina elastica interna was associated to media hypertrophy. In 69%, venous lumen was dilated, frequently in association with wall thickening, while only in 12 specimens all vascular layers were reduced. Occlusive endoluminal thrombi were evident in 12%. At last the Authors underline how the wall pathologic modifications do not involve all the veins within the same plexus, and stress on the possible physiopathologic relationships between this fact and different haemodynamic and clinic conditions.

[Gastrointestinal stromal tumors: a case with mixed muscular-neuronal origin].

GIST have still today controversial aspects of their histogenesis that are reflected on the classification and prognosis. It's showed a particular case with mixed muscular-neuronal histogenesis that supposes totipotent cell origin of these neoplasms. Diagnosis, classification and prognosis are very difficult to evaluate; surgery at the moment is the only useful treatment modality.

[Pre- and postoperative external biliary drainage in patients with obstructive jaundice caused by neoplasm of the pancreatic head].

The external biliary drainage in severe jaundice secondary to pancreatic carcinoma acts differently in pre, intra, and postoperative period. In the preoperative period the drainage enables to lower the direct bilirubinemia and the intrahepatic biliary stasis and consequently the complications linked to the impaired hepatic and renal function. During the operation the catheter acts as a guide in performing the biliodigestive anastomosis. In the postoperative period the external drainage of most of daily biliary secretion protects the biliodigestive anastomosis during the postoperative paralytic ileus, and prevents the fistula development along the pancreatic jejunal anastomosis.
