Abstract
BACKGROUND The benefits of laparoscopic hemi-hepatectomy compared to open hemi-hepatectomy are not clear. OBJECTIVE This study aims to share our experience with the laparoscopic hemi-hepatectomy compared to an open approach. METHODS A total of 40 consecutive laparoscopically started hemi-hepatectomy (intention-to-treat analysis) cases between August 2012 and October 2015 were matched against open cases using the following criteria: laterality of surgery and pathology (essential criteria); American Society of Anesthesiologists score, body mass index, pre-operative bilirubin, neo-adjuvant chemotherapy, additional procedures, portal vein embolization, and presence of cirrhosis/fibrosis on histology (secondary criteria); age and gender (tertiary criteria). Hand-assisted and extended hemi-hepatectomy cases were excluded from the study. The two groups were compared for blood loss, operative time, hospital stay, morbidity, mortality, and oncological outcomes. All complications were quantified using the Clavien-Dindo classification. RESULTS Two groups were well matched (p = 1.00). In the two groups, 10 patients had left and 30 had right hemi-hepatectomy. Overall conversion rate was 15%. Median length of hospital and high dependency unit stay was less in the intention to treat laparoscopic hemi-hepatectomy group: 6 versus 8 days, p = 0.025 and 1 versus 2 days, p = 0.07. Median operative time was longer in the intention to treat laparoscopic hemi-hepatectomy group: 420 min (range: 389.5-480) versus 305 min (range: 238.8-348.8; p = 0.001). Intra-operative blood loss was equivalent, but the overall blood transfusions were higher in the intention to treat laparoscopic hemi-hepatectomy (50 vs 29 units, p = 0.36). The overall morbidity (18 vs 20 patients, p = 0.65), mortality (2.5%), and the positive resection margin status were similar (18% vs 21%, p = 0.76). The 1- (87.5% vs 92.5%, p = 0.71) and 3-year survival (70% vs 72.5%, p = 1.00) was also similar. CONCLUSIONS We observed lower hospital and high dependency unit stay in the laparoscopic group. However, the laparoscopic approach was associated with longer operating time and a non-significant increase in blood transfusion requirements. There was no difference in morbidity, mortality, re-admission rate, and oncological outcomes.

Abstract
Background Risk prediction techniques commonly used in liver surgery include the American Society of Anesthesiologists (ASA) grading, Charlson Comorbidity Index (CCI) and cardiopulmonary exercise tests (CPET). This study compares the utility of these techniques along with the number of segments resected as predictive tools in liver surgery. Methods A review of a unit database of patients undergoing liver resection between February 2008 and January 2015 was undertaken. Patient demographics, ASA, CCI and CPET variables were recorded along with resection size. Clavien-Dindo grade III–V complications were used as a composite outcome in analyses. Association between predictive variables and outcome was assessed by univariate and multivariate techniques. Results One hundred and seventy-two resections in 168 patients were identified. Grade III–V complications occurred after 42 (24.4%) liver resections. In univariate analysis of CPET variables, ventilatory equivalents for CO2 (VEqCO2) was associated with outcome. CCI score, but not ASA grade, was also associated with outcome. In multivariate analysis, the odds ratio of developing grade III–V complications for incremental increases in VEqCO2, CCI and number of liver segments resected were 1.09, 1.49 and 2.94, respectively. Conclusions Of the techniques evaluated, resection size provides the simplest and most discriminating predictor of significant complications following liver surgery.

Abstract
AIMS To determine the relative significance of radiological signs in determining the resectability of peri-ampullary cancer (PC) and to assess the value of multi-phase imaging in detecting these findings. MATERIALS AND METHODS Blinded, double re-reporting of preoperative imaging from five hospitals was undertaken of 411 patients undergoing surgery for PC over an 8-year period, of whom 119 patients were found to be inoperable at the time of surgery. RESULTS The median tumour size was 26.7 mm and the proportion of patients reported to have regional lymphadenopathy (RL), venous (VI) and arterial involvement (AI) was 24.7%, 11.5%, and 3.9%, respectively and was similar regardless of the number of contrast phases undertaken. Significant associations were, however, noted between individual risk factors: VI was closely associated with tumour size (p=0.002) and AI (p<0.0001). In multivariate analysis AI, VI, and RL were independently associated with resectability (relative risk of resection=0.05, 0.31, and 0.51, respectively). Tumour size, however, was not associated with resectability when VI was included in the multivariate model. CONCLUSIONS The use of multiple vascular contrast phases has no measureable impact on the rate of determination of tumour resectability of PC. In preoperative staging, AI is the most significant adverse finding for resectability. Large tumour diameter is not an adverse finding in isolation from other risk factors.

Abstract
AIMS To assess the potential association between the change in diameter of colorectal liver metastases between pre-operative imaging and liver resection and disease-free survival in patients who do not receive pre-operative liver-directed chemotherapy. MATERIALS AND METHODS Analysis of a prospectively maintained database of patients undergoing liver resection for colorectal liver metastases between 2005 and 2012 was undertaken. Change in tumour size was assessed by comparing the maximum tumour diameter at radiological diagnosis determined by imaging and the maximum tumour diameter measured at examination of the resected specimen in 157 patients. RESULTS The median interval from first scan to surgery was 99 days and the median increase in tumour diameter in this interval was 38%, equivalent to a tumour doubling time (DT) of 47 days. Tumour DT prior to liver resection was longer in patients with T1 primary tumours (119 days) than T2-4 tumours (44 days) and shorter in patients undergoing repeat surgery for intra-hepatic recurrence (33 days) than before primary resection (49 days). The median disease-free survival of the whole cohort was 1.57 years (0.2-7.3) and multivariate analysis revealed no association between tumour DT prior to surgery and disease-free survival. CONCLUSIONS The rate of growth of colorectal liver metastases prior to surgery should not be used as a prognostic factor when considering the role of resection.

Abstract
INTRODUCTION Emergency surgery is performed on patients with appendicitis in the belief that inflammation of the appendix may progress to necrosis and perforation. Many cases of appendicitis, however, resolve with conservative treatment, and necrotic appendicitis may represent a different disease rather than the end result of inflammation of the appendix. We wished to explore the relationship between the interval to surgery after admission to hospital with appendicitis and the proportion of patients developing necrosis. METHODS Appendicectomy operations performed between 2005 and 2010 were reviewed. End points included age, sex, interval from admission to surgery, and final pathological diagnosis. RESULTS A total of 2403 evaluable patients were identified (1266 females). Necrotic appendicitis occurred more commonly in children (17.5%) and the elderly (25.4%) compared with adults (10.5%). The median interval to surgery of patients with normal histology (17.1 h) was longer than the time to removal of inflamed (13 h) or necrotic (13.5 h) appendices (p < 0.001).The ratio of necrotic to inflamed appendicitis in the entire cohort was 0.24. Multivariate analysis reveals that necrosis of the appendix is more common in children and the elderly and that the proportion of patients with necrosis does not change with increasing interval to surgery. DISCUSSION Our observations show that appendicitis is not more likely to lead to perforation if a short delay prior to surgery is allowed. In addition, our findings add weight to the increasing volume of data showing that necrosis of the appendix is a disease different from simple inflammation.

Abstract
INTRODUCTION The results of surgical resection and palliative chemotherapy use in hilar cholangiocarcinoma (HC) have been well publicised but the proportion of patients able to undergo these treatments and the comparative outcomes in a population of patients with HC are less well known. METHODS Patients with HC were identified by review of all patients undergoing percutaneous cholangiography over a nine-year period (2002-2010) in a tertiary facility. The treatment undertaken and outcomes were recorded. RESULTS Overall, 68 patients were identified (37 female) with a median age of 70 years. Forty-five (66%) were treated solely by insertion of a metal stent (median survival 4.73 months) and nine (13%) also received palliative chemotherapy (median survival 13.7 months). Persisting jaundice after stent insertion was noted in 18 of 35 patients (51%) tested within one month of death. Fourteen patients (21%) underwent surgical resection (median survival 20.2 months). CONCLUSIONS Patients undergoing surgical resection had significantly longer survival than those receiving only a palliative stent but not compared with those also receiving palliative chemotherapy, with short-term follow-up. Only a third of patients, however, receive active treatment (surgery or chemotherapy) and improvements in long-term biliary palliation are needed.

Abstract
A total of 103 consecutive patients with gastric adenocarcinoma was assessed for intra-abdominal spread of malignancy using ultrasonography, computed tomography (CT) and laparoscopy under general anaesthesia. Histologically proven metastases were to the liver in 27 patients, lymph nodes in 49 and directly to peritoneum in 13. All modalities showed a high specificity (92-100 per cent) for each type of metastasis. Laparoscopy was more sensitive in detecting hepatic, nodal and peritoneal metastases; the relative performance of laparoscopy was best with regard to hepatic metastases. Ultrasonography and CT were particularly poor at detecting nodal and peritoneal metastases. There was no significant morbidity and no mortality associated with laparoscopy, which was more accurate in preoperative staging of gastric cancer than ultrasonography or CT.
