Esophageal mucosal tissue blood flow was measured using endoscopic laser doppler flowmetry in 12 cases of normal esophagus (control group), 6 cases of reflux esophagitis, 10 cases of advanced thoracic esophageal cancer and 5 cases of anastomotic benign stricture of cervical esophagus. Normal esophagus (control group) revealed good mucosal tissue blood flow more than 25 ml/min/100g, though the blood flow of upper part of esophagus was relatively lower than that of lower part of esophagus. Reflux esophagitis group showed the same blood flow as that of control group, and both advanced thoracic esophageal cancer group and anastomotic benign stricture of cervical esophagus group revealed significantly lower blood flow compared with the control group. The blood flow of advanced thoracic esophageal cancer seemed to change depending on the location, type of endscopic findings and depth of invasion of each cancer.
