This study is based on the statistical analysis of 110 patients with liver abscess, treated surgically and medically at the Department of Surgery and Internal Medicine, Jeonbug National University Hospital from January, 1976 to December, 1982.
The results were as follows:
1) Of the 110 cases of liver abscess, 56 cases(50.9%) were pyogenic, 38 cases(34.5%) were amebic and 16 cases(14.6%) were mixed.
2) In sex incidence, the male to female ratio was 2.6 : 1 and peak age incidence was the 5th decade.
3) The liver abscess was commonly located in the right lobe(80.0%) than in the left(8.2%) and both or multiple were involved in 11.8% of cases.
4) The commonset clinical manifestation in order of frequency were R.U.Q. pain(65.4%),fever and chillness (56. 3%), chest pain and dyspnea(26.4%) and hepatomegaly(26.4%).
5) The most common past history and associated disease were enterocolitis(9 cases/15 cases) in amebic liver abscess and gallstone(7 cases/9 cases) in pyogenic liver abscess.
6) The duration of symptom was commonly involved from 1 week to 3 weeks(68.2%).
7) The anemia below 10.0 gm% of hemoglobin was seen in 17.2% of cases and the leuko-cytosis over 10, 000/㎣ in 88. 1%.
8) An increased alkaline phosphatase was the most reliable laboratory aid(55.4%).
9) The abnormal chest X-ray findings were seen in 79.1% of cases and the most frequent abnormal finding was elevation of right hemidiaphragm(28.2%).
10) Pus culture was performed in all cases, of which 40.9% was positive, and E. coli was the most frequently found organism (14. 5%).
11) Liver scans showed space occupying lesion in 80.8% of cases.
12) The incidence of complication was 30% in liver abscess.
13) The overall mortality rate was 12.7% and the chief causes of death were sepsis, respiratory failure, hepatic failure, hemorrhagic shock and heart failure.
14) The approach methods of surgical treatment were open drainage via transcostal or transabdominal and open thoracotomy.
