[Transabdominal ultrtasonic investigation of the upper parts of the gastro-intestinal tract in diagnostics of ulcer disease and decision on the strategy before and after surgery].

The authors present an analysis of results of the diagnostics and treatment of 293 patients admitted to the Alexandrovskaya hospital of St. Petersburg in 1995-2005 for gastroduodenal ulcer, including 202 patients after operative treatment. The morpho-functional state of the upper parts of the gastro-intestinal tract was assessed by the method of transabdominal sonography of the stomach and duodenum with a convection transducer 5 MHz in on-line regimen. The informative value of the method corresponds to the reference diagnostics method, sensitivity of the method was 91%, specificity--95%. The ultrasound investigation of the stomach and duodenum is a highly efficient method of diagnostics of the morpho-functional state of the gastro-duodenal system giving a reliable interpretation of the local morphological and functional changes, ulcer disease included, corresponding to the efficiency of the reference diagnostics methods. The sonography allows a dynamic control of the treatment process, assessment of the alterations after surgery on the stomach and duodenum and decision on the exact surgical strategy.
