UNLABELLED: The aim of this prospective study was to study the impact of biopsies of liver metastases guided by laparoscopic ultrasound (LUS) and to evaluate various biopsy techniques.

MATERIAL AND METHODS: Laparoscopy with LUS was performed on 18 consecutive patients with liver metastases considered to be surgically curable. Any new liver lesion which could lead to a therapeutic modification was biopsied, with a forceps or guided by LUS using four different techniques.

RESULTS: Of 17 patients successfully examined, a biopsy was indicated in 12 cases (71%), extension of the surgical procedure was decided in four cases (24%), and laparotomy was avoided in six cases (35%). The preoperative staging was correct in 15 stages (88%) and incorrect in two cases (12%). The positioning of the puncture needle in the axis of the scanning plane by "free hand" or in association with an abdominal transducer was effective, without complications.

CONCLUSION: Any liver lesion discovered by LUS which could lead to a modification or abstention of surgery should be biopsied, with LUS-guidance in the case of deep lesions. However, an optimal and universal guiding system for LUS-probes, has not yet been developed.
