Impact of the content of collagens I and III and their ratio in cancer patients for the formation of postoperative ventral hernia.

Comparative morphological analysis of collagens I and III content in the connective tissue in various groups of surgical patients, including tumor patients with ventral hernias, was carried out. The total content of collagen and collagen I/III ratio were the highest in cancer patients in comparison with non-tumor patients with hernias and with patients without hernias or tumors. Hence, factors not associated with collagen synthesis predominate in the pathogenesis of hernia formation in patients operated for malignant tumors.

[The morphology of a main bronchial stump area after diaphragmopexy or omentopexy].

The present paper presents 5 microscopic investigations of the morphology of a major bronchial stump area or tracheobronchial anastomosis after tightly fixing a vascularized diaphragmatic or omental flap. The cadaveric material of female patients who had died in different periods after diaphragmopexy or omentopexy was investigated. The authors' observations support the fact that diaphragmatic or omental flaps tightly sutured to the tracheobronchial wall can provide its revascularization and regeneration of the bronchial stump or tracheobronchial anastomosis.
