Simple abdomen film has played an important role in decision of emergency operations in patients with theabdominal trauma. Nowadays, it still acts as a primary and inevitable processes in emergency condition. At theDept.of Radiology, Hanil Hospital, 70 patients, who were laparotomied due to penetrating or nonpenetratingabdominal trauma, were observed and analyzed with simple abdomen film after comparison with the operativefindings. The reults are as follows; 1. Most frequent age distribution was 10 to 39 years and marked 70%. Male wasin 90% incidence. 2. Penetrating injury largely involved the small bowel and abdominal wall. Non-penetratinginjury usually involved the spleen, small bowel, liver, kidney, pancreas, duodenum. 3. Single organ injuryoccurrred in higher incidence at the spleen, liver, kidney and pancreas. 4. Organ distribution was 26% in spleen,22% in small bowel, 14% in liver, 11% in abdominal wall, 7% in pancreas, 7% in kidney, 5% in duodenum, 4% in GBand CBD, 2% in diaphragm, 2% in colon , and 1% in stomach. 5. The specific roentgen findings and their frequencywhich useful in differential diagnosis at abdominal trauma, were as follows; a) flank fluid; detectablepossibility was 71% in liver laceration, 69% in spleen laceration and 57% in pancreas laceration. b) ipsilateralpsoas shadow obliteration; Detectable possibility was 57% in liver laceration, 69% in spleen laceration. c) freeair; Detectable possibility was 60% in duodenal perforation, and 365 in perforation of upper part of small bowel.d) Reflex ileus; Detectable pssibility was 64% in small bowel, 50% in liver laceration and 35% in spleenlaceration. e) rib fracture; Detectable possibility was 36% in liver laceration and 23% in spleen laceration. f)pleural effusion; Detectable possibility was 29% in liver laceration and 27% in spleen laceration.
