Abstract: | OBJECTIVE: To evaluate the feasibility of laparoscopic cryoablation for the management of hepatic metastases. DESIGN: Retrospective review. SETTING: Tertiary referral center. PATIENTS: Nine patients were evaluated by laparoscopy for planned laparoscopic cryoablation of hepatic metastases at The Cleveland Clinic Foundation, Cleveland, Ohio, from April 1996 to May 1997. RESULTS: Laparoscopic exploration revealed diffuse extrahepatic disease not identified by preoperative studies in 2 patients. The remaining 7 patients underwent 9 cryotherapy sessions. During 4 of the cryotherapy sessions, ultrasonography demonstrated unrecognized additional treatable hepatic lesions. An average of 3 lesions (range, 2-5) were treated. Operative time averaged 3.5 hours with a mean intraoperative blood loss of 235 mL. One patient had significant intraoperative hemorrhage requiring conversion to open hepatic resection for bleeding control. Eight of the 9 patients tolerated normal diets and ambulated independently on the first postoperative day. Following cryotherapy, 4 of the patients developed fever without an infectious source. One patient developed a postoperative bile leak requiring percutaneous biliary stenting. Postoperative hospital stay averaged 4.5 days (median, 4 days; range, 2-14 days). At a mean follow-up of 9 months, 4 of the 7 patients treated are alive without evidence of disease, 2 are alive with disease, and 1 patient with a pancreatic primary tumor has died of disease. CONCLUSIONS: Laparoscopy with laparoscopic ultrasonography is a useful tool in evaluating patients with hepatic metastases. Laparoscopic cryoablation is feasible and may result in lower postoperative morbidity in patients receiving aggressive treatment for inoperable hepatic metastases. |
