ABSTRACT
In order to evaluate age related changes of the elastic fiber system in the interfoveolar ligament, we studied the deep inguinal ring from 33 male cadavers aged from stillborn to 76 years. Selective and alternated staining methods for elastic fibers were performed to differentiate oxytalan, elaunin, and mature elastic fibers. We confirmed quantitative changes of the elastic fiber system with aging. There was a significant and progressive reduction of the oxytalan fibers (responsible for tissue resistance) and a significant increment in the mature elastic and elaunin fibers (responsible for tissue elasticity). Furthermore, there were structural changes in the thickness, shortness and curling of these mature elastic fibers. These changes induced loss of the elastic fiber function and loss of the interfoveolar ligament compliance. These factors predispose individuals to the development of indirect inguinal hernias that frequently emerge in adults and aged individuals, especially above the fifth decade.

In order to relieve complete obstruction of the thoracic esophagus due to spinocellular carcinoma, thirteen patients, all of them in good or at least regular general conditions were submitted to a bypass using a isoperistaltic gastric tube. The disease itself was treated by radiotherapy after surgery. Only one patient died at the hospital due to an error in the radiotherapy schedule. Cervical fistula was observed in six patients seven days after surgery; local treatment was enough for complete healing in five out of six. In one patient surgery was performed in order to repair the anastomotic area. Stenosis was observed in three patients but in all cases it was possible to overcome it by endoscopy. With the progress of the disease other complications were observed such as hemoptysis and respiratory distress. The survival rate was nine months (running between five and sixteen) but it should be noted that swallow capacity was maintained until death. The employed of a bypass of isoperistaltic gastric tube seems to be a desirable alternative in the treatment of esophageal cancer because it allows the reestablishment of deglutition before any treatment such as radiotherapy alone or combined with surgery.

The authors report one case of peritoneal splenosis. The patient submitted to a gastrectomy had a past history of traumatic rupture of the spleen. The morphologic and immunologic aspects of splenosis are discussed. The value of imaging splenic tissue by scynthscanning are pointed out in basis of infection prophylaxis.
