Purpose
The purpose of this study is to assess the feasibility, safety and efficacy of High Intensity Focused Ultrasound (HIFU) patients undergoing hepatectomy for colorectal liver metastases. This is a phase I/II study.

| Official Title: | A Phase I-II Study to Evaluate, in Patients Operated for a Hepatic Resection of Colorectal Liver Metastases, a High Intensity Focused Ultrasound (HIFU) Procedure: Feasibility, Safety and Accuracy. |
- First step: Ability to shoot and supplementary duration of intervention, to use the medical device following requested asepsis procedures and no evidence of hurt on peripheral tissues and to keep vital signs stable [ Time Frame: At the end of surgery (realized about 1 week after enrollment) ] [ Designated as safety issue: Yes ]
- Phase IIa - First step: accuracy of shootings on a precise area [ Time Frame: At the end of surgery (realized about 1 week after enrollment) ] [ Designated as safety issue: No ]both the distance between the hurt epicentre generated by hifu and a mark. These sizes will be measured in mm during anatomopathological exam.
- Phase IIb: possibility of ≤ 15 shootings, safety margin ≥ 5 mm in healthy liver. [ Time Frame: At the end of surgery (realized about 1 week after enrollment) ] [ Designated as safety issue: No ]
- Phase IIa - Second step: accuracy of shootings on a zone to be spared [ Time Frame: At the end of surgery (realized about 1 week after enrollment) ] [ Designated as safety issue: No ]between the hurt limit and a vessel border previously marked. These sizes will be measured in mm during anatomopathological exam.
- Phase I: adjust the probe position to different liver segments and patient physical structure. [ Time Frame: At the end of surgery (realized about 1 week after enrollment) ] [ Designated as safety issue: No ]The aim is to be free to generate a HIFU hurt in at least 80 % of the total liver volume
- Phase I: Possibility to set a stationary mark, at given depth, echographically detectable [ Time Frame: At the end of surgery (realized about 1 week after enrollment) ] [ Designated as safety issue: No ]
- Phase I: Possibility to spot echographically a previously Patent Blue or Methylene blue marked vessel [ Time Frame: At the end of surgery (realized about 1 week after enrollment) ] [ Designated as safety issue: No ]
- Phase I: Mean duration to achieve each step expressed in minutes(initialization, conditioning, targeting, shooting) [ Time Frame: At the end of surgery (realized about 1 week after enrollment) ] [ Designated as safety issue: No ]
- Phase I: description of outline during perioperative echography [ Time Frame: At the end of surgery (realized about 1 week after enrollment) ] [ Designated as safety issue: No ]diameters, depth, volume
- Phase I: description of limits during anatomopathological analysis [ Time Frame: At the end of surgery (realized about 1 week after enrollment) ] [ Designated as safety issue: No ]diameters, depth, volume
- Phase I: distance between the mark / marked vessel and the hurt limits during anatomopathological analysis [ Time Frame: At the end of surgery (realized about 1 week after enrollment) ] [ Designated as safety issue: No ]Precise measure given in mm by the anatomopathologist
- Phase II: safety of the device [ Time Frame: At the end of surgery (realized about 1 week after enrollment) ] [ Designated as safety issue: Yes ]no evidence of hurt on peripheral tissues (Glisson capsule on the opposite side of the HIFU shootings entrance area, retro-peritoneal, retro-hepatic tissues and diaphragm
- Phase II: assessment of vital signs during shooting phase [ Time Frame: At the end of surgery (realized about 1 week after enrollment) ] [ Designated as safety issue: Yes ]hemodynamic, respiratory, body temperature
- Phase IIa: correlation between hurt perioperative echographic and postoperative macroscopic, measures [ Time Frame: At the end of surgery (realized about 1 week after enrollment) ] [ Designated as safety issue: No ]hurt dimensions comparison (diameters, depth, volume, etc. - in mm), blind-measured, with echography in a first time and in a second time, right after the resection, in anatomopathology

| Arms | Assigned Interventions |
|---|---|
| Experimental: Phase I : HIFU |
Procedure: HIFU
The shootings will concern the healthy liver to remove, distant to the important vascular structures and metastases. Two HIFU shootings will be made on each patient:
|
| Experimental: Phase IIa : HIFU |
Procedure: HIFU
The shootings will concern healthy liver to be resected, distant (step 1) then close (step 2) to the important vascular structures of the liver. Several shootings HIFU will be made on each patient (ideally 4 hurts, minimum 2 hurts)
|
| Experimental: Phase IIb : HIFU |
Procedure: HIFU
Shootings will concern small metastases (≤ 20 mm) and peri lesional healthy liver. They will be juxtaposed on multiple plans in order to generate a large hurt containing the metastasis targeted and guaranteeing a sufficient safety margin in healthy liver. Several metastases can be treated in the same patient |
