Background: Surgical resection, where appropriate, remains one of the best treatment options for hepatocellular carcinoma (HCC), however outcomes can be compromised by the development of liver failure. We reviewed our experience of liver resection for HCC patients to identify factors that may predict the development of post-hepatectomy liver failure (PHLF) and survival., Methods: A single centre retrospective cohort study. Data was collected between 1999 and 2017 from all patients undergoing HCC resection in a tertiary university hospital from electronic medical records. PHLF was defined as per the International Study Group for Liver Surgery criteria. Variables with p < 0.15 on univariate analysis were included in a multivariate binary logistic regression model. Kaplan-Meier analyses were used to determine correlations with overall survival (OS) and disease-free survival (DFS), and variables with p < 0.15 on univariate analysis selected for a step-down Cox proportional hazard regression model., Results: Overall, 120 patients underwent liver resection within the study period, of which 22 (18%) developed PHLF. Patients with normal INR ≤1.20 at day 2 did not develop PHLF whereas patients with INR >1.60 were at significant risk. Resection of multiple tumours (odds ratio 21.63, p = 0.002) and deranged postoperative day 2 INR>1.6 (odds ratio 21.05, p < 0.0001) were identified as independent prognostic markers of PHLF., Conclusion: The use of INR measurement at day 2 predicts PHLF and may enable us to objectively identify and stratify patients who may be eligible for enhanced recovery programs from those who will merit close monitoring in high dependency areas., Competing Interests: Declaration of competing interest Silva ANS reports no conflict of interest.

Aim: A large, prospectively collected, clinical database was analysed to determine the various pre- and intra-operative factors affecting anastomotic leakage (AL) in colorectal surgery., Method: Data on 17 518 patients having a colorectal resection with anastomosis, taken from the 2013 American College of Surgeons National Surgical Quality Improvement Program database, were included in the study. Multivariable logistic regression analysis was carried out to identify risk-adjusted predictive factors for AL. Statistical significance was set at P < 0.05 and confidence intervals were reported at the 95% level., Results: The AL rate was 3.9% (687/17 518). Younger patients, male gender and an American Society of Anesthesiology (ASA) score of ≥ 3 (P < 0.001), smoking (P = 0.001), diabetes (P = 0.035), a preoperative serum albumin level of < 4 g/dl (P = 0.030), elective rectal cancer surgery (P = 0.024), emergency colectomy for bleeding (P = 0.013) and splenic flexure mobilization (P = 0.043) were associated with an increased risk of AL. Preoperative oral antibiotics (P < 0.001), right hemicolectomy (open or laparoscopic) and laparoscopic partial colectomy were associated with a reduced risk of AL compared with the entire group. Body mass index, preoperative chemotherapy, emergency surgery and mechanical bowel preparation were not related to AL., Conclusion: In contrast to most studies, younger age was found to be an independent risk factor for AL. The risk for AL was lower with laparoscopic partial colectomy and open or laparoscopic right hemicolectomy. Preoperative oral antibiotic preparation significantly reduces the risk of AL and should be incorporated as a standard protocol., (Colorectal Disease © 2016 The Association of Coloproctology of Great Britain and Ireland.)
