Abstract
For the purpose of evaluating the tissue blood flow reducing effect on loweresophagus and cardiac portion of the stomach after transabdominal mucosal transection operation for esophageal varices, 28 adult mongrel dogs were used and devided into (A) 18 as the control (B) 10 caused to have portal hypertention for present study.Closed-couple thermoelectrode flow meter was used to measure the tissue blood flow at lower esophagus and carciac portion of the stomach following this procedures (1) ligating short gastric vessels, (2) ligating left gastric vessels, (3) transecting only the mucosal tube of the esophagus, (4) completely transecting of the esophagus.The following results were obtained.1. Effect on lower esophagus: transecting only the mucosal tube of the esophagus reduced 36.0±11.0% of the tissue blood flow and ligating short gastric vessels or left gastric vessels also reviewed a rather large effect.2. Effect on cardiac portion of the stomach: ligating the short gastric vessels reduced 2.5±3.0% of the tissue blood flow, while ligating of the left gastric vessels reduced more effectively 13.6±6.5%.
