Background/purpose: One-stage resection of primary colon cancer and synchronous liver metastases is considered an effective strategy of cure. A laparoscopic approach may represent a safe and advantageous choice for selected patients with the aim of improving the early outcome.
Methods: Between January 2008 and October 2008, 7 patients underwent one-stage laparoscopic resection for primary colorectal cancer combined with laparoscopic or robot-assisted liver resection.
Results: A total of five laparoscopic left-colon, one right-colon, and one rectal resections were performed. Three patients underwent preoperative left-colon stenting and two received neoadjuvant chemotherapy. The patient with rectal cancer underwent neoadjuvant radiotherapy. Liver procedures included one bisegmentectomy (segments 2, 3), 3 segmentectomies, 6 metastasectomies, and four laparoscopic ultrasound-guided radiofrequency ablations (LUG-RFAs). One patient with multiple liver metastases was managed by a two-stage hepatectomy partially conducted by a totally laparoscopic approach. The overall postoperative morbidity was null. The median hospital stay was 10 days (range 7-10 days).
Conclusions: This pilot study suggests that laparoscopic one-stage colon and liver resection is feasible and safe. Robot assistance may facilitate liver resection, increasing the number of patients who may benefit from a minimally invasive operation.
