The value of gastropneumography in the diagnosis of acute gastroduodenal perforation

From 1982, The Abdominal Surgery Department of the Hospital 103 had applied gastropneumography to diagnose suspected gastroduodenal perforation in patients without subphrenic sickle-air. Air was pumped through nasogastric tube with a volume of 700 ml to 1000 ml. By this technique, definite diagnosis of perforation was made and the surgery was indicated early. Sensitivity of the technique was 82.6%. This technique should be recommended in medical units, where emergency abdominal operation can be performed early to restrict potential complications.
