[Intraoperative instrumental examination in stomach cancer].

Ultrasound examination and laser autofluorescent spectroscopy were used intraoperatively for evaluation of gastric cancer dissemination. These methods were efficient in differentiation of cancer and benign tumors, estimation of cancer dissemination, revealing of metastases in the liver and lymph nodes. The use of these methods made it possible to increase sensitivity and specificity of estimation of cancer infiltration to 100% and of revealing lymph nodes metastases to 90% and 76%, respectively.
