Abstract
Abstract
Introduction
Hepatic resection is the only potentially curative treatment for patients with colorectal liver metastases (CLM). Patient selection is key, but there is wide variation in practice. Pre-operative chemotherapy can improve oncological outcomes, however chemotherapy-associated liver injury (CALI) may hinder liver regenerative capacity. Standard pre-operative assessments fail to accurately capture factors such as CALI and future liver remnant (FLR) function. The CLiFF and CoNoR studies utilise two novel assessment techniques, aiming to improve patient outcomes.
Method
The CLiFF study prospectively assesses two primary outcomes in 35 patients undergoing pre-operative chemotherapy for CLM: 1) change in liver function (via LiMAx test: direct assessment of hepatic functional capacity), and 2) change in liver fat (via advanced MR imaging (in-house spectroscopy and modified Dixon technique, scaled up via Perspectum LiverMultiScan)). The CoNoR study assesses potential added benefit of these novel tools in CLM resectability decision-making via sequential workstreams: a systematic review and international hepatobiliary expert interviews inform the online survey, assessing added benefit via online MDT scenarios.
Result
Preliminary CLiFF analysis suggests that CALI changes in liver fat and function are unrelated. Liver fat analysis techniques are compared and correlated with digital histological analysis. The CoNoR systematic review identifies key factors influencing CLM resectability decision-making and informs the international expert interviews, scheduled to occur during a February 2020 international hepatobiliary conference.
Conclusion
These studies are the first to assess where these novel tools might be utilised to maximal patient benefit within the Hepatobiliary MDT, and the first systematic review in CLM resectability decision-making.
Take-home message
These two linked studies evaluate the use of two novel assessment tools in the treatment of colorectal liver metastases, with the potential to improve patient selection for curative resection and patient outcomes.

Abstract
INTRODUCTION Recent consensus guidelines suggest that the laparoscopic approach may be a useful, safe and feasible approach in emergency general surgery. Despite this, the UK National Emergency Laparotomy Audit (NELA) suggests the rate of laparoscopy is low (9% fully laparoscopic) and slow to increase over time. A European survey found uptake to be variable. This UK survey was therefore undertaken to establish current UK practice and to determine factors affecting implementation. MATERIALS AND METHODS A questionnaire survey of currently practising UK consultant general surgeons was carried out by the North West Surgical Research Collaborative, using a secure web-based database maintained by the North West Surgical Trials Centre. RESULTS A total of 151 completed questionnaires were returned from 22 UK centres; 18% of respondents were unaware that laparoscopic cases should be reported to NELA. Appendicectomy (97%) and cholecystectomy (87%) were routinely performed laparoscopically. Laparoscopy was infrequently used in perforation, ischaemia or obstructed hernias. There appears to be equipoise regarding laparoscopic compared with open surgery in small-bowel obstruction among all subspecialty emergency general surgeons, in perforated peptic ulcer among upper gastrointestinal surgeons and in Hinchey III diverticulitis among colorectal surgeons. CONCLUSION Uptake of laparoscopy in UK emergency general surgery is influenced by surgeon preference, subspecialty, patient and operative factors. Further research into outcomes may help to identify areas of greatest potential benefit. The rate of laparoscopy reported by NELA may be an underestimate due to the 18% of surgeons unaware that laparoscopic cases should be reported, which may affect the validity of analyses performed from this dataset.

Abstract
Abstract
Background
Older adults undergoing emergency abdominal surgery have significantly poorer outcomes than younger adults. For those who survive, the level of care required on discharge from hospital is unknown and such information could guide decision-making. The ELF (Emergency Laparotomy and Frailty) study aimed to determine whether preoperative frailty in older adults was associated with increased dependence at the time of discharge.
Methods
The ELF study was a UK-wide multicentre prospective cohort study of older patients (65 years or more) undergoing emergency laparotomy during March and June 2017. The objective was to establish whether preoperative frailty was associated with increased care level at discharge compared with preoperative care level. The analysis used a multilevel logistic regression adjusted for preadmission frailty, patient age, sex and care level.
Results
A total of 934 patients were included from 49 hospitals. Mean(s.d.) age was 76·2(6·8) years, with 57·6 per cent women; 20·2 per cent were frail. Some 37·4 per cent of older adults had an increased care level at discharge. Increasing frailty was associated with increased discharge care level, with greater predictive power than age. The adjusted odds ratio for an increase in care level was 4·48 (95 per cent c.i. 2·03 to 9·91) for apparently vulnerable patients (Clinical Frailty Score (CFS) 4), 5·94 (2·54 to 13·90) for those mildly frail (CFS 5) and 7·88 (2·97 to 20·79) for those moderately or severely frail (CFS 6 or 7), compared with patients who were fit.
Conclusion
Over 37 per cent of older adults undergoing emergency laparotomy required increased care at discharge. Frailty scoring was a significant predictor, and should be integrated into all acute surgical units to aid shared decision-making and discharge planning.

Abstract
AIM The study aimed to identify the incidence of early stoma problems after surgery for colorectal cancer to identify predisposing factors and to assess the effect on discharge from hospital and the greater need for community stoma care. METHOD A prospective study of 192 patients was carried out over a six-month period in the 13 units of the Greater Manchester and Cheshire Cancer Network. Stoma problems were categorized into fistula, leakage, pancaking, necrosis, retraction, separation, stenosis, skin problems, parastomal hernia, suboptimal stoma site and need for resiting or refashioning. Differences in incidence between units (anonymized) were analysed, and the effect of stoma complications on length of hospital stay and the need for additional community stoma care was determined. RESULTS One hundred and ninety-two patients with stomas were included, of which 52 (27.1%) were identified as being problematic (range 0-66.7% between units). Significant risk factors included stoma type (colostomy) (P < 0.05), short stoma length (P = 0.006), higher BMI (P = 0.043), emergency surgery (P = 0.002) and lack of preoperative site marking (P < 0.001). Problematic stomas were associated with longer hospital stay (P < 0.001) and increased community care (P < 0.001). CONCLUSION Stoma type, stoma length, body mass index, emergency surgery and lack of preoperative marking were significant risk factors. Overall complication rates compare favourably with other studies.
