The benign liver tumors have diverse disease entities. Hemangioma, nonparasitic liver cyst, liver cell adenoma, focal nodular hyperplasia, hepatobiliary cystadenoma, hamartoma etc, are included in spite of their rarity. We reviewed 36 patients
with
benign liver tumor from 1981 January to 1990 December operated at Department of General Surgery, Seoul National University Hospital including organizing liver abscess, and Ecchinococcal cyst because of their frequent misdiagnosis and tumor like
foatures
preoperatively.
Sex ratio was 1.6 : 1 (22 : 14) and mean age was 52.4 years. Preoperative diagnostic tools were ultrasonography, CT, antiography, radioisotope scan and peritoneoscopy, and their preoperative diagnostic accuracy was at most 50%.
Their entities were hemangiomal 11 cases, organizing liver abscess 9 cases, nonparasitic liver cyst 9 cases, Ecchinococcal cyst 2 cases hamartoma 1 case, adenoma 1 case, biliary cystdenoma 1 case and two cases of double primary lesions: livr cyst
and
liver abscess, hemangioma and hamartoma.
The operations were performed as to preoperative diagnosis; right lobectomy 7 cases, left lobectomy 4 cases, left lateral segmentectomy 4 cases, subsegmentectomy 12 cases, mass excision 3 cases and unroofing 5 cases in nonparasitic liver cyst.
The
operative complications were presented in 23 cases (62.2%); pleural effusion 12 cases. intraabdominal abscess 11 cases, and atelectasis 10 cases without mortality.
