Lysosomal enzymes and severity of saphen varicosis.

The severity of the varicosis estimated clinically and histologically is well correlated with the seric levels of beta-acetylglucosaminidase and beta-glucuronidase. No correlations are observed with the arylsulfatase level in serum nor with the levels in venous tissue for the three enzymes.

[Cancers of the thoracic esophagus in gastrectomized patients. Technical problems].

The authors report three cases of carcinoma of the thoracic part of the esophagus who had previously undergone gastrectomy. They study, in the absence of a stomach, the possibilities of restoration of digestive continuity after esophagectomy and describe three possibilities: -- mobilisation and use of the remaining gastric stump; --esophageal resection and anastomosis restoring continuity; -- colonic interposition. Of the three procedures used, only the first and last are advised by the authors.
