Mucosal tissue blood flow (TBF) of the cervical anastomotic portion after esophageal reconstruction was studied in humans to determine the relationship between mucosal TBF and benign anastomotic stricture. Two groups participated in the study. One was 24 healthy controls. The other was 14 patients who previously received both esophageal resection for esophageal cancer and reconstruction with a stomach roll, including both anastomotic stricture and non-stricture group. Mucosal TBF was measured by endoscopic laser-Doppler flowmetry. The control group had a TBF of more than 26 ml/min/100 g in all portions, and the TBF of the patient group was significantly lower. Furthermore, the anastomotic stricture group had a significantly lower TBF in the anastomotic portion than the anastomotic non-stricture group. These results indicate that low mucosal TBF is strongly related to the occurrence of cervical anastomotic stricture in patients after esophageal reconstruction.
