The role of obstruction of the pathogenesis of acute appendicitis was studied by measuring the pressure in the appendix peroperatively in 33 patients undergoing appendectomy because of suspected acute appendicitis. The technique involved insertion of a fine needle via the apex into the lumen of the appendix and measurement of the hydrostatic pressure required to inject a saline solution. In all six patients with gangrenous appendix and in two patients with phlegmonous appendix there were signs of obstruction of the appendix lumen expressed as raised intraluminal pressure. In 19 patients found at operation to have phlegmonous appendix there were no signs of obstruction. The experimental data suggest that obstruction is not an important factor in the causation of acute appendicitis, but may develop as a result of the inflammatory process.
通过对33例因疑似急性阑尾炎而接受阑尾切除术的患者在手术中测量阑尾内压力，研究了梗阻在急性阑尾炎发病机制中的作用。该技术包括通过阑尾尖端插入一根细针至阑尾腔内，并测量注入盐溶液所需的静水压力。在所有6例坏疽性阑尾炎患者和2例蜂窝织炎性阑尾炎患者中，均有阑尾腔梗阻的迹象，表现为腔内压力升高。在手术中发现的19例蜂窝织炎性阑尾炎患者中，没有梗阻迹象。实验数据表明，梗阻不是急性阑尾炎病因中的重要因素，但可能是炎症过程的结果。
