To analyze the effect of IOUS on surgical decision making, we performed a
retrospective study of 45 patients who had exploratory laparotomy and IOUS
for liver neoplasms. Preoperative lesion detection was compared with
intraoperative findings. The effect of IOUS on the choice of surgical
procedure was analyzed. Preoperative imaging detected 67% of lesions, 78%
when combined with surgical inspection and palpation, and 97% were
recognized by IOUS. Surgery was modified in 23 of 45 cases (51%); 19 of
those 23 cases (83%) were based on IOUS findings alone. IOUS demonstrated
superior lesion detection over noninvasive preoperative liver imaging, and
IOUS significantly affected surgical decision making.
