Diagnostic significance of dynamic and static esophagoscintigraphy in esophageal cancer before and after operative treatment

A total of 381 esophagoscintigraphies were performed in 93 subjects: 34 - control group, 46 - patients with esophageal cancer before treatment and 47 - at different terms after operation. Examination of the motor-evacuative function of the esophagus was carried out on scintillation gamma-camera PHO/GAMMA-HP NUCLEAR CHICAGO, with CLINCOM-computer. The procedure consists in consecutive determination of esophageal transit labelled liquid and solid food. A physiological nutritive solid bolus, labelled with 99mTc-phyton or 113mIn-coinol, which leaves no trace activity on the esophageal mucosa, is proposed. Qualitative and quantitative characteristics of esophageal function and Down Esophageal Sphincter (DES) in norm and in esophageal cancer before and after treatment was demonstrated. Esophageal disfunction, with or without DES damage, is observed at the following conditions: for liquid food - Esophageal Transit Time (ETT) > 5 s, clearance < 87,2% and passage rate < 21,6%/s; for solid food - ETT < 9 s, clearance < 86,6% and passege rate < 11,39%/s. In esophageal cancer before treatment the organ function suffers to a different degree, directly proportional to the degree of tumor growth and out of proportion to the clinical manifestations of dysphagia. In 83,7% of the patients reflux at the site of the anastomosis was observed; this may be a reason for development of postoperative esophagitis. Esophagoscontigraphy allows to detect early motor disturbances, degree of dissemination of the pathologic process and degree of reestablishment of esophageal function after treatment
