Objective To discuss the injury spectrum and traumatic condition spectrum of trauma of abdominal organs in recent years. Methods Data of 247 cases with trauma on abdominal organ admitted in our hospital from 1999 to 2001 were analyzed in respects of injury spectrum, sex, age, vocation and injury causes of the cases with trauma of abdominal organs. Traumatic condition was evaluated by abridged injury score-injury severity score (AIS-ISS). Results There were 54 cases with trauma of abdominal organs in 1999, 72 in 2000 and 121 in 2001. Of all, 241 cases were cured but 6 died, with a fatality rate of 2.5%. The occurrence frequency of trauma of abdominal organs could be ranked in turn as follows: the spleen (43.2%), the kidney (18.8%), the liver (13.7%), the small intestine (6.5%),the bladder (4.8%), the pancreas (3.8%), the colon (3.8%), the stomach, the duodenum and the rectum. A total of 192 cases at age under 40 years accounted for 77.7% . Three injury causes ranked the first three places were traffic accident in 95 cases (38.5%), fall in 54 (21.9%), kick and boxing in 36 (14.6%), respectively. Of all, 168 cases had only intraabdominal injuries, of which 80 (47.6%) were with AIS=3, 32 (19.0%) with AIS=4 and 10 (6.0%) with AIS=5; and the other 79 cases (32.0%) were complicated by multiple trauma, with ISS ≥16 in 27 cases (34.2%) and ISS ≥25 in 8 (10.1%). Conclusions With the increase of vehicles and current personnel, the trauma of abdominal organs caused by traffic accident, accidental wound and conflict increases accordingly. People most apt to organ injuries are farmers, students and workers. Three organs ranked first three places are the spleen, the kidney and the liver. More than half cases are injured severely in accordance with AIS. To decrease trauma of abdominal organs, we must strengthen the education on traffic safety to raise their bewareness of injuries.
