Resection margin status is a known prognosticator in patients who undergo resection for hilar cholangiocarcinoma. However, the influence of an isolated positive circumferential margin on clinical outcome is unclear.Patients with resected de novo hilar cholangiocarcinoma from two European hepatobiliary centres (Medical University of Vienna and Aintree University Hospital, 2006-2016) were classified according to resection margin status (negative, surgically positive, isolated circumferentially positive) and investigated with respect to overall survival (OS), recurrence-free survival (RFS) and recurrence pattern.Eighty-three (48 male/35 female) patients were enrolled. The median age was 64 years (range 33-80). The median follow-up was 21.7 months (range 0.3-92.4). Forty (48%) patients had negative resection margins, 25 (30%) had an isolated positive circumferential margin and 18 (22%) had a positive surgical margin. The 5-year OS rates in patients with negative, isolated positive circumferential and positive surgical resection margins were 47%, 33% and 0%, respectively. Median OS was 45.6, 32.7 and 14.5 months, respectively (log rank, P = 0.011). Upon multivariable Cox regression analysis, resection margin status and lymph node status remained statistically significant (P 0.05). No difference with respect to RFS and recurrence pattern was found between the groups (P 0.05).Our data show that these three resection margin types were associated with different clinical outcomes. Circumferential margin status may therefore serve as a novel prognostic biomarker.

There is limited evidence for the use of enhanced recovery after surgery (ERAS) in patients undergoing hepatectomy, and the impact of the evolution of ERAS over time has not been examined. This study sought to evaluate the effect of an evolving ERAS program in patients undergoing hepatectomy for colorectal liver metastases (CRLM).A multimodal ERAS program was introduced in 2/2008. Consecutive patients undergoing hepatectomy for CRLM between 2/2008 and 9/2012 were included in the study. Data were collected prospectively. Retrospective analysis compared an early ERAS cohort (2/2008-4/2010) with a later cohort with a matured ERAS program (5/2010-8/2012).Length of stay reduced as experience of ERAS increased (Log-rank χ(2) = 10.43, P = 0.001). Although median length of stay remained unchanged (6 days), the probability of hospitalization beyond 10 days was 25% in the early cohort compared with 7% in the later cohort. Critical care utilization reduced over time (75.5% vs. 54.7%, P 0.0001). Complications occurred in 38.2%, with no difference in between cohorts. One postoperative death occurred in the early cohort (0.3%).This study suggests that as experience of ERAS evolves, there is a progressive reduction in hospitalization and critical care admission. This is without any increase in morbidity and mortality.

To date, there is limited data on the liver-first approach in the management of colorectal liver metastases (CRLM). The aim of the study was to assess the outcomes of the liver-first approach for patients with synchronous CRLM in two tertiary referral centers.Patients with stage IV colorectal cancer selected for the liver-first approach from January 2009 to December 2012 in two tertiary referral centers were included. Data collated included demographics, chemotherapy, operative findings, histo-pathological features, and survival.Thirty-seven patients with synchronous CRLM were considered for the liver-first approach. Twenty-five patients had rectal cancer. All patients underwent induction chemotherapy. Thirty patients underwent hepatic resections with no post-operative deaths. Following liver resection, five patients failed to proceed to colorectal resection and one patient had complete response to chemo-radiotherapy. Of the 25 patients that completed the liver-first approach, 13 patients had recurrent disease, of which 12 patients died. The overall 1- and 3-year survival rates were 65.9% and 30.4%, respectively.The liver-first approach is a feasible strategy for patients with synchronous CRLM and may improve survival in selected patients. The selection of patients should be incorporated in a multidisciplinary approach to achieve the best possible outcomes.
