Intraluminal pressure measurements were made during enema examination of 10 patients undergoing full column studies and 10 patients receiving air-contrast studies. There was no significant difference between the pressure in the distal colon of the two groups. All pressures were less than those produced by Valsalva maneuver or straight leg raising, and were generally less than those previously found to be necessary to rupture the colon. The authors believe that the findings should dispel any fear that an air-contrast examination is more hazardous than a full column study. Perforations occurring during these procedures are more likely related to disease of the colon wall or local trauma.
在对10例接受全柱检查的患者和10例接受气钡双重造影检查的患者进行灌肠检查时，进行了腔内压力测量。两组患者远端结肠的压力无显著差异。所有压力均低于瓦尔萨尔瓦动作或直腿抬高所产生的压力，且通常低于先前发现的导致结肠破裂所需的压力。作者认为，这些发现应消除人们对气钡双重造影检查比全柱检查更具危险性的担忧。这些检查过程中发生的穿孔更可能与结肠壁疾病或局部创伤有关。
