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]. / Cancers de l'oesophage thoracique chez les gastrectomisés. Incidences techniques

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.
