Abstract
Up to 50% of patients with colorectal carcinoma (CRC) present with liver metastases (CLM) throughout their course. Complete resection of both sites provides the only chance for cure. Either a staged or simultaneous resection is feasible. The latter avoids delays in adjuvant systemic chemotherapy but may increase technical complexity and perioperative complications. We aim to evaluate our initial outcomes of simultaneous CRC and CLM resections with a focus on the robotic technique. With institutional review board approval, we followed 26 consecutive patients who underwent simultaneous/concomitant liver and colorectal resection. Major liver resection is defined as resection of ≥3 contiguous Couinaud segments. Data are presented as median (mean ± SD). Patients were 64 (63 ± 14.0) years old. Body mass index was 29 (29 ± 5.7) kg/m2. 54% of patients had prior abdominal operation(s). A majority of patients were >ASA class III (73%), underwent major liver resection (62%) with robotic approach (77%). In the robotic cohort, there were no unplanned conversions to open. Estimated blood loss was 150 (210 ± 181.8) ml. Total operative duration was 446 (463 ± 93.6) minutes. Negative margins (R0) were obtained in all patients. Postoperative complication of Clavien-Dindo≥3 occurred in three patients, including one requiring reoperation with end ileostomy for anastomotic leak. Length of stay was 5 (6 ± 3.5) days. Three patients were readmitted within 30days after discharge, none for reoperation. There was no 90-day mortality. Our cohort of concomitant CRC and CLM resection demonstrates safety and efficacy via both the open and robotic approach.
