[Connection of immune status, nutritional status and postoperative complications in patients after surgery for organic esophageal stricture].

The postoperative complications were analysed in 64 patients after operation for stricture of the esophagus. The underfeeding in consequence of the esophagus stricture reduced the cellular immune functions and increased the operative risk. The comparison of the feeding and immune parameters of patients with benign and malign strictures of the esophagus showed that the poor immune reactivity is caused by the underfeeding first of all and not by the immune depression due the tumor.
