The safety, reliability, and technique of laparoscopic liver biopsy we
re evaluated in 22 consecutive patients with coagulation abnormalities
who were considered high risk for standard percutaneous liver biopsy.
Fifty-eight biopsies were performed in 15 men and seven women. All pa
tients had a prolonged prothrombin time (>13.5 seconds), bleeding time
(>9 minutes), or thrombocytopenia (<100,000 TH/UL). Ten patients (45%
) had more pronounced coagulation abnormalities defined as a prolonged
PT >2.5 seconds or less than or equal to 30% control, platelet count
<50,000 TH/UL, or bleeding time twice normal. Thirteen patients (59%)
had both thrombocytopenia and a prolonged PT. Ascites was present in 1
9 patients (86%) and portal hypertension in 16 (73%). Laparoscopic liv
er biopsy was performed under general anesthesia, most commonly using
two trocar sites and an open laparoscopic technique. Hemostasis was mo
st effectively obtained by application of direct pressure and topical
gelfoam and thrombin. A postoperative drop in hemoglobin of greater th
an or equal to 1 gm per cent occurred in four patients. One patient re
quired laparotomy for postoperative bleeding and was the only patient
requiring transfusion of red blood cells. Other complications included
two minor ascitic leaks, one small subcapsular hematoma, and one woun
d infection. In conclusion, laparoscopic liver biopsy can be performed
safely and reliably in patients with conditions contraindicating perc
utaneous biopsy.
