Background And Aims:
The aim of this retrospective study was to establish whether Fong's risk score can predict rate of resectability and whether laparoscopic exploration with ultrasonography can reduce the number of useless laparotomies to any extent.
Material And Methods:
Fong's score was calculated for each of the 43 potential resectable patients. We analysed: the relation between score and resectability; the probability of unnecessary laparotomy with respect to each level of score; and which of the five Fong parameters was the most indicative of non-resectability. None of our patients was submitted to preoperative laparoscopic staging.
Results:
All patients with Fong's score 0 were submitted to liver resection, whereas only 76.9% with score 1, 58.3% with score 2, and 66.6% with score 3. No patients had score 4 and 5. "CEA level" is the parameter that best predicts the "non-resectability" of metastases. In the subgroup with score 0-1, laparoscopy would have spared 12% of unnecessary laparotomies, whereas in subgroup 2-3 this percentage would have risen to 38.9.
Conclusions:
The above data allowed us to quantify statistically the risk associated with non-resectability of liver metastases in a directly proportional manner as the score progresses.
