Abstract

112 cases of spontaneous penumoperitoenum, the causes of which were confirmed by clinical and surgicalprocedure at Presbyterian Medical Center from Jan. 1977, to July, 1981, were reviewed radiologically. The resultwas as follows; 1. Perforationmof duodenal ulcer (46/112:41.1%), stomach ulcer(22/112:19.6%), and stomach cancer(11/112:9.8%) were the three most common causes of spontaneous penumoperitoneum. These were 70.5% of all causes.2. The most common site of free gas was both subdiaphragmatic areas(46:41.1%). Others were Rt. subdiaphragmaticonly (31:27.7%), both subdiaphragmatic with subhepatic (16:14.3%), Rt. subdiaphragmatic with subhepatic (7:6.2%),Rt.subdiaphragmatic only (5:4.4%), diffuse in abdomen(4:3.6%), and subhepatic only (3:2.7%). So 92.0%(103/112)were located in RUQ. 3. The radiological shape of free gas was classified : crescent (52:46.4%) of small amount;half-moon(21:18.8%) of moderate amount; larger of diffuse (39:34.8%) of large amount. 4. The age between 31 and 60occupied 69.1%(77/122), and male was predominant(5.2 times). 5. The patient's position showing free air mostfrequently was erect.
