Liver tumors and minimally invasive surgery: a feasibility study.
Laparoscopic liver resection has not yet been established, although recent reports document that liver resection can be performed safely by the laparoscopic approach. Other interventional procedures like cryoablation have also been introduced in treatment of liver metastases. In this report 11 liver resections performed laparoscopically in eight patients are presented. Six patients had colorectal metastases, one a metastases from a malignant melanoma, and one patient had focal nodular hyperplasia. Two patients received synchronous cryoablation of remaining liver metastases. During follow up, two patients received percutaneous cryoablation of liver recurrences monitored by an open configuration magnetic resonance scanner. All except one of the tumors we attempted to remove had free resection margins (re-resection of new metastasis). No complications occurred except an atelectasis of the left lower pulmonary lobe in one patient. Median postoperative hospital stay was 3 days, and median postoperative opioid-dependent days was 1. The report demonstrates that minimally invasive techniques may safely be combined in hepatic intervention, and that the advantages of minimally invasive surgery, such as reduced hospital stay and less patient discomfort, also applies to liver resections.
