RESUMEN
PURPOSE: Despite the benefits of palliative care (PC) in pancreatic cancer, little is known about patients who access PC. This observational study examines the characteristics of patients with pancreatic cancer at their first episode of PC. METHODS: First-time, specialist PC episodes captured through the Palliative Care Outcomes Collaboration (PCOC), in Victoria, Australia between 2014 and 2020, for pancreatic cancer, were identified. Multivariable logistic regression analyses examined the impact of patient- and service-level characteristics on symptom burden (measured through patient-reported outcome measures and clinician-rated scores) at first PC episode. RESULTS: Of 2890 eligible episodes, 45% began when the patient was deteriorating and 32% ended in death. High fatigue and appetite-related distress were most common. Generally, increasing age, higher performance status and more recent year of diagnosis predicted lower symptom burden. No significant differences were noted between symptom burden of regional/remote versus major city dwellers; however, only 11% of episodes recorded the patient as a regional/remote resident. A greater proportion of first episodes for non-English-speaking patients began when the patient was unstable, deteriorating or terminal, ended in death and were more likely to be associated with high family/carer problems. Community PC setting predicted high symptom burden, with the exception of pain. CONCLUSION: A large proportion of first-time specialist PC episodes in pancreatic cancer begin at a deteriorating phase and end in death, suggesting late access to PC. Timely referrals to community-based specialist PC, access in regional/remote areas, as well as development of culturally diverse support systems require further investigation.

BACKGROUND: Pancreatic and oesophagogastric (OG) cancers have a dismal prognosis and high symptom burden, with supportive care forming an integral component of the care provided to patients. This study aimed to explore the supportive care experiences of patients and caregivers living with pancreatic and OG cancers in order to identify perceived opportunities for improvement. METHODS: Semi-structured individual interviews were conducted with people living with pancreatic and OG cancers, and their caregivers, across Victoria, Australia during 2020. Interviews were thematically analysed to identify common themes. RESULTS: Forty-one participants were interviewed, including 30 patients and 11 caregivers. Three overarching themes, each with multiple sub-themes, were identified: (i) inadequate support for symptoms and issues across the cancer journey (ii) caregiver's desire for greater support, and (iii) a multidisciplinary care team is the hallmark of a positive supportive care experience. Generally, those who had access to a cancer care coordinator and/or a palliative care team recounted more positive supportive care experiences. CONCLUSION: Unmet needs are prevalent across the pancreatic and OG cancer journey, with supportive care provided to varying levels of satisfaction. Greater awareness of and access to high-quality multidisciplinary support services is greatly desired by both patients with pancreatic and OG cancer and their caregivers.

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) has poor survival. Current treatments offer little likelihood of cure or long-term survival. This systematic review evaluates prognostic models predicting overall survival in patients diagnosed with PDAC. METHODS: We conducted a comprehensive search of eight electronic databases from their date of inception through to December 2019. Studies that published models predicting survival in patients with PDAC were identified. RESULTS: 3297 studies were identified; 187 full-text articles were retrieved and 54 studies of 49 unique prognostic models were included. Of these, 28 (57.1%) were conducted in patients with advanced disease, 17 (34.7%) with resectable disease, and four (8.2%) in all patients. 34 (69.4%) models were validated, and 35 (71.4%) reported model discrimination, with only five models reporting values >0.70 in both derivation and validation cohorts. Many (n = 27) had a moderate to high risk of bias and most (n = 33) were developed using retrospective data. No variables were unanimously found to be predictive of survival when included in more than one study. CONCLUSION: Most prognostic models were developed using retrospective data and performed poorly. Future research should validate instruments performing well locally in international cohorts and investigate other potential predictors of survival.

BACKGROUND: This study: (i) assessed compliance with a consensus set of quality indicators (QIs) in pancreatic cancer (PC); and (ii) evaluated the association between compliance with these QIs and survival. METHODS: Four years of data were collected for patients diagnosed with PC. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). A multivariable analysis tested the relationship between significant patient and hospital characteristics, patient cluster effects within hospitals and survival. RESULTS: 1061 patients were eligible for this study. Significant association with improved survival were: (i) in the potentially resectable group having adjuvant chemotherapy administered following surgery or a reason documented (HR, 0.29; 95 CI, 0.19-0.46); (ii) in the locally advanced group included having chemotherapy ± chemoradiation, or a reason documented for not undergoing treatment (HR, 0.38; 95 CI, 0.25-0.58); and (iii) in the metastatic disease group included having documented performance status at presentation (HR, 0.65; 95 CI, 0.47-0.89), being seen by an oncologist in the absence of treatment (HR, 0.48; 95 CI, 0.31-0.77), and disease management discussed at a multidisciplinary team meeting (HR, 0.79; 95 CI, 0.64-0.96). CONCLUSION: Capture of a concise data set has enabled quality of care to be assessed.

BACKGROUND: The aim of this systematic review is to examine patient-reported outcome measures (PROMs), their attributes and application in patients with pancreatic cancer (PC). METHOD: A systematic literature search was undertaken of articles published to June 2018 to identify PROMs applied in primary studies in PC. Characteristics of the included studies and PROMs were described with identified scales grouped into five domains. The psychometric properties of the identified PROMs were further assessed for reliability and validity among patients with PC. RESULTS: From 1688 studies screened, 170 were included. Almost half (48%) were conducted in patients with unresectable PC; the majority of these (68%) were evaluated in randomized controlled trials. Median questionnaire completion rates fell below 10% of the original cohort within 12 months in patients with unresectable PC compared to 75% in patients with resectable PC. Seventy PROMs were identified, 32 measuring unidimensional parameters (e.g. pain) and 35 measuring multidimensional (e.g. quality of life) constructs. Only five (7%) PROMs were disease-specific and 13 (19%) were validated in patients with PC. Fifty scales were grouped into 19 physical, 9 psychological, 6 psychiatric, 9 social and 7 other domains. CONCLUSION: Three multidimensional PROMs, the: (i) FACT-HEP in unresectable PC; (ii) QLQ-PAN26 (in conjunction with its core QLQ-C30 PROM) in resectable PC; and (iii) MDASI-GI are recommended as instruments to capture quality of life in patients with PC. Summarised scales and psychometric evaluation provide a framework to choose PROMs for scales not captured by the recommended PROMs.

BACKGROUND: Best practise care optimises survival and quality of life in patients with pancreatic cancer (PC), but there is evidence of variability in management and suboptimal care for some patients. Monitoring practise is necessary to underpin improvement initiatives. We aimed to develop a core set of quality indicators that measure quality of care across the disease trajectory. METHODS: A modified, three-round Delphi survey was performed among experts with wide experience in PC care across three states in Australia. A total of 107 potential quality indicators were identified from the literature and divided into five areas: diagnosis and staging, surgery, other treatment, patient management and outcomes. A further six indicators were added by the panel, increasing potential quality indicators to 113. Rated on a scale of 1-9, indicators with high median importance and feasibility (score 7-9) and low disagreement (<1) were considered in the candidate set. RESULTS: From 113 potential quality indicators, 34 indicators met the inclusion criteria and 27 (7 diagnosis and staging, 5 surgical, 4 other treatment, 5 patient management, 6 outcome) were included in the final set. CONCLUSIONS: The developed indicator set can be applied as a tool for internal quality improvement, comparative quality reporting, public reporting and research in PC care.

OBJECTIVE: This study hypothesized that tumor size, number of tumors, surgical approach, and tumor histology significantly affected microwave ablation (MWA) success and recurrence-free survival. BACKGROUND: Although many hepatobiliary centers have adopted MWA, the factors that influence local control are not well described. METHODS: Consecutive patients with hepatic malignancy treated by MWA were included from 4 high-volume institutions (2003-2011) and grouped by histology: hepatocellular carcinoma (HCC), colorectal liver metastases, neuroendocrine liver metastases, and other cancers. Independent significance of outcome variables was established with logistic regression and Cox proportional hazards models. RESULTS: Four hundred fifty patients were treated with 473 procedures (139 HCC, 198 colorectal liver metastases, 61 neuroendocrine liver metastases, and 75 other) for a total of 875 tumors. Median follow-up was 18 months. Concurrent hepatectomy was performed in 178 patients (38%), and when performed was associated with greater morbidity. Complete ablation was confirmed for 839 of 865 tumors (97.0%) on follow-up cross-sectional imaging (10 were unevaluable). A surgical approach (open, laparoscopic, or percutaneous) had no significant impact on complication rates, recurrence, or survival. The local recurrence rate was 6.0% overall and was highest for HCC (10.1%, P = 0.045) and percutaneously treated lesions (14.1%, P = 0.014). In adjusted models, tumor size 3 cm or more predicted poorer recurrence-free survival (hazard ratio: 1.60, 95% CI: 1.02-2.50, P = 0.039). CONCLUSIONS: In this large data set, patients with 3 cm or more tumors showed a propensity for early recurrence, regardless of histology. Higher rates of local recurrence were noted in HCC patients, which may reflect underlying liver disease. There were no significant differences in morbidity or survival based on the surgical approach; however, local recurrence rates were highest for percutaneously ablated tumors.

BACKGROUND AND OBJECTIVES: Neutrophil-to-lymphocyte ratio (NLR) is simple, inexpensive, and has been proposed to be predictive in hepatocellular carcinoma (HCC) in Europe and Asia. We aimed to evaluate whether NLR at presentation in a Western center provides any prognostic value compared to other common prognostic scores. METHODS: NLR was calculated for 75 consecutive patients at presentation with HCC and regression models were used to analyze its value for predicting treatment strategy and short-term survival with Child-Pugh and Model for End Stage Liver Disease (MELD). RESULTS: NLR was not predictive of future treatment regimens with hepatectomy, liver transplant, or transarterial chemoembolization (TACE; odds ratio [OR]: 0.85, 95% confidence interval [CI]: 0.71-1.02, P = 0.079) as compared the predictive value of MELD (OR: 0.81, CI: 0.72-0.93, P = 0.002) or Child-Pugh (OR: 0.48, CI: 0.34-0.69, P < 0.001). Adding additional adjustment for treatment, NLR did not correlate with short-term overall survival (hazard ratio [HR]: 1.09, CI: 0.95-1.24, P = 0.227). MELD also did not correlate with overall survival (HR: 1.04, CI: 0.96-1.13, P = 0.357) whereas Child-Pugh (HR: 1.56, CI: 1.10-2.19, P = 0.011) was predictive. CONCLUSIONS: This study does not support the prognostic value of NLR to guide therapy for HCC in a Western center, whereas MELD and Child-Pugh score were more predictive.

The implementation of a laparoscope-holding robot in minimally invasive surgery enhances the efficiency and safety of the operation. However, the extra robot control task can increase the cognitive load on surgeons. A suitable interface may simplify the control task and reduce the surgeon load. Foot interfaces are commonly used for commanding laparoscope-holding robots, with two control strategies available: decoupled control permits only one Cartesian axis actuation, known as decoupled commands; hybrid control allows for both decoupled commands and multiple axes actuation, known as coupled commands. This paper aims to determine the optimal control strategy for foot interfaces by investigating two common assumptions in the literature: (1) Decoupled control is believed to result in better predictability of the final laparoscopic view orientation, and (2) Hybrid control has the efficiency advantage in laparoscope control. Our user study with 11 experienced and trainee surgeons shows that decoupled control has better predictability than hybrid control, while both approaches are equally efficient. In addition, using two surgery-like tasks in a simulator, users' choice of decoupled and coupled commands is analysed based on their level of surgical experience and the nature of the movement. Results show that trainee surgeons tend to issue more commands than the more experienced participants. Single decoupled commands were frequently used in small view adjustments, while a mixture of coupled and decoupled commands was preferred in larger view adjustments. A guideline for foot interface control strategy selection is provided.

BACKGROUND: Complete surgical removal of pancreatic ductal adenocarcinoma (PDAC) is central to all curative treatment approaches for this aggressive disease, yet this is only possible in patients technically amenable to resection. Hence, an accurate assessment of whether patients are suitable for surgery is of paramount importance. The SCANPatient trial aims to test whether implementing a structured synoptic radiological report results in increased institutional accuracy in defining surgical resectability of non-metastatic PDAC. METHODS: SCANPatient is a batched, stepped wedge, comparative effectiveness, cluster randomised clinical trial. The trial will be conducted at 33 Australian hospitals all of which hold regular multi-disciplinary team meetings (MDMs) to discuss newly diagnosed patients with PDAC. Each site is required to manage a minimum of 20 patients per year (across all stages). Hospitals will be randomised to begin synoptic reporting within a batched, stepped wedge design. Initially all hospitals will continue to use their current reporting method; within each batch, after each 6-month period, a randomly selected group of hospitals will commence using the synoptic reports, until all hospitals are using synoptic reporting. Each hospital will provide data from patients who (i) are aged 18 or older; (ii) have suspected PDAC and have an abdominal CT scan, and (iii) are presented at a participating MDM. Non-metastatic patients will be documented as one of the following categories: (1) locally advanced and surgically unresectable; (2) borderline resectable; or (3) anatomically clearly resectable (Note: Metastatic disease is treated as a separate category). Data collection will last for 36 months in each batch, and a total of 2400 patients will be included. DISCUSSION: Better classifying patients with non-metastatic PDAC as having tumours that are either clearly resectable, borderline or locally advanced and unresectable may improve patient outcomes by optimising care and treatment planning. The borderline resectable group are a small but important cohort in whom surgery with curative intent may be considered; however, inconsistencies with definitions and an understanding of resectability status means these patients are often incorrectly classified and hence overlooked for curative options. TRIAL REGISTRATION: The SCANPatient trial was registered on 17th May 2023 in the Australian New Zealand Clinical Trials Registry (ANZCTR) (ACTRN12623000508673).

INTRODUCTION: Stage of pancreatic carcinoma at diagnosis is a strong prognostic indicator of morbidity and mortality, yet is poorly notified to population-based cancer registries ("cancer registries"). Registry-derived stage (RD-Stage) provides a method for cancer registries to use available data sources to compile and record stage in a consistent way. This project describes the development and validation of rules to capture RD-Stage (pancreatic carcinoma) and applies the rules to data currently captured in each Australian cancer registry. MATERIALS AND METHODS: Rules for deriving RD-stage (pancreatic carcinoma) were developed using the American Joint Commission on Cancer (AJCC) Staging Manual 8th edition and endorsed by an Expert Working Group comprising specialists responsible for delivering care to patients diagnosed with pancreatic carcinoma, cancer registry epidemiologists and medical coders. Completeness of data fields required to calculate RD-Stage (pancreatic carcinoma) and an overall proportion of cases for whom RD stage could be assigned was assessed using data collected by each Australian cancer registry, for period 2018-2019. A validation study compared RD-Stage (pancreatic carcinoma) calculated by the Victorian Cancer Registry with clinical stage captured by the Upper Gastro-intestinal Cancer Registry (UGICR). RESULTS: RD-Stage (pancreatic carcinoma) could not be calculated in 4/8 (50%) of cancer registries; one did not collect the required data elements while three used a staging system not compatible with RD-Stage requirements. Of the four cancer registries able to calculate RD-Stage, baseline completeness ranged from 9% to 76%. Validation of RD-Stage (pancreatic carcinoma) with UGICR data indicated that there was insufficient data available in VCR to stage 174/457 (38%) cases and that stage was unknown in 189/457 (41%) cases in the UGICR. Yet, where it could be derived, there was very good concordance at stage level (I, II, III, IV) between the two datasets. (95.2% concordance], Kendall's coefficient = 0.92). CONCLUSION: There is a lack of standardisation of data elements and data sources available to cancer registries at a national level, resulting in poor capacity to currently capture RD-Stage (pancreatic carcinoma). RD-Stage provides an excellent tool to cancer registries to capture stage when data elements required to calculate it are available to cancer registries.

INTRODUCTION: The 5-year survival of patients with gallbladder cancer remains low. However, patients can be stratified into prognostic categories based on established factors such as T, N, and R status. New concepts regarding prognostic significance of lymph node disease, the importance of residual gallbladder fossa disease, and the gravity of presentation with jaundice are reviewed. In addition, a number of new prognostic factors proposed in recent years are considered. METHODS: PubMed was searched for "gallbladder cancer" with builder "date-completion" 2008 to present. A total of 1,490 articles were screened from which 168 were retrieved. From this, 40 articles specifically related to prognosis form the basis for this review. DISCUSSION: Key factors of prognostic significance remain T and N stage and R0 resection. Residual disease either in the gallbladder fossa, lymph nodes, or cystic duct margin dictates hepatectomy, lymphadenectomy and bile duct resection, respectively. Adequate lymphadenectomy requires removal of six nodes, and hepatectomy must be sufficient to achieve R0. Subtleties regarding lymph node ratio, significance of pathological features such as dedifferentiation, and budding may hold value for stratifying patients with early stage disease, but require further investigation.

BACKGROUND: Gallbladder cancer (GBC) is a rare malignancy, yet certain groups are at higher risk. Knowledge of predisposing factors may facilitate earlier diagnosis by enabling targeted investigations into otherwise non-specific presenting signs and symptoms. Detecting GBC in its initial stages offers patients their best chance of cure. METHODS: PubMed was searched for recent articles (2008-2012) on the topic of risk factors for GBC. Of 1490 initial entries, 32 manuscripts reporting on risk factors for GBC were included in this review. RESULTS: New molecular perspectives on cholesterol cycling, hormonal factors and bacterial infection provide fresh insights into the established risk factors of gallstones, female gender and geographic locality. The significance of polyps in predisposing to GBC is probably overstated given the known dysplasia-carcinoma and adenoma-carcinoma sequences active in this disease. Bacteria such as Salmonella species may contribute to regional variations in disease prevalence and might represent powerful targets of therapy to reduce incidences in high-risk areas. Traditional risk factors such as porcelain gallbladder, Mirizzi's syndrome and bile reflux remain important as predisposing factors. CONCLUSIONS: Subcentimetre gallbladder polyps rarely become cancerous. Because gallbladder wall thickening is often the first sign of malignancy, all gallbladder imaging should be scrutinized carefully for this feature.

OBJECTIVES: The impact of pre-transplant hepatitis B virus (HBV) and/or hepatitis C virus (HCV) infection in patients with hepatocellular carcinoma (HCC) is not well described. This study was conducted to test the hypothesis that viral status is an independent predictor of retransplantation rates, graft survival (GS) and overall survival (OS) in patients undergoing liver transplantation for HCC. METHODS: Patients with HCC were identified from the Organ Procurement and Transplantation Network database (2005-2012), and categorized by viral status according to these categories: HBV-/HCV-; HBV+/HCV-; HBV-/HCV+, and HBV+/HCV+. RESULTS: Of 7742 patients transplanted for HCC, 7060 had known HBV and HCV status. Five-year GS and OS were highest in recipients who were HBV+/HCV-, at 75% and 78%, respectively, compared with patients who were HBV-/HCV- (GS = 63%, OS = 66%), HBV-/HCV+ (GS = 64%, OS = 60%) or HBV+/HCV+ (GS = 60%, OS = 62%). In multivariable analyses, HBV-/HCV+ patients were more likely than HBV+/HCV- patients to undergo repeat transplantation. Patients who were HBV-/HCV+ also had poorer GS and OS than both HBV-/HCV- and HBV+/HCV- patients. Other independent predictors of poorer OS included older age, higher Model for End-stage Liver Disease score, African-American race, and diabetes. The few HBV+/HCV+ patients (n = 138) showed trends toward fewer retransplantations, prolonged GS and prolonged OS compared with HBV-/HCV+ patients. In adjusted models, antiviral medications did not impact GS or OS. CONCLUSIONS: In the era of modern selection criteria, viral status is an independent predictor of outcome following liver transplantation for HCC. Both HBV-/HCV- and HBV+/HCV- patients have superior GS and OS compared with HBV-/HCV+ patients.

INTRODUCTION: A comprehensive review of the surgical management of injuries sustained by deployed members of the Australian Defence Force (ADF) during Operation SLIPPER and HIGHROAD in Afghanistan has not previously been undertaken. Understanding the mechanism of injury, injury types sustained and surgical intervention undertaken should provide valuable information for future health planning and surgical capability determination. METHODS: Retrospective chart review of scanned medical records of injured personnel identified through casualty register examination was undertaken. RESULTS: There were 259 ADF personnel injured in Afghanistan between January 2002 and December 2021, of which 53 were seriously (SI), or very seriously injured (VSI). Case notes for 90 of 101 casualties including those sustaining VSI, SI and those classified as being in satisfactory condition, but likely requiring surgery and/or returned to Australia following trauma, were available for review. Most patients with VSI/SI required surgery (93%) and most were returned to Australia following injury (91%). Almost two-thirds (64.4%) of initial surgery was undertaken at a Role 2 E medical treatment facility (MTF). Gun-shot wound (GSW) was the commonest injuring mechanism (47%) followed by blast injury (39.6%). Orthopaedic (32.2%) and soft tissue initial wound surgery (47.1%) were the commonest surgical procedures. DISCUSSION: Surgical management of military trauma was undertaken at multiple sites by multiple surgical teams from different nationalities delivering exceptional results and conforming to modern principles of damage control surgery. The military trauma system is distinctly different from its civilian counterpart with dispersion of assets requiring multiple episodes of casualty movement between echelons of care rather than centralization at level 1 trauma centres. Despite this, excellent results are achievable. Strengthening lines of communication and documentation would reinforce the ability of the military trauma system to continue to provide such results, and regular oversight and review of surgical caseload would align military trauma surgery with civilian standards. The benchmark set by the United States Department of Defense Trauma Registry should be replicated for Australian led combat operations and modified to facilitate interoperability to support future coalition combat operations.

This is the first case report of 43-year-old lady with a myxoid hepatic adenoma which demonstrated significant contrast uptake during hepatobiliary phase imaging. This highlights the potential for a missed diagnosis and likely subsequent malignant transformation in a young patient in whom it was initially presumed to be focal nodular hyperplasia with no further surveillance.
RESUMEN
BACKGROUND: The Victorian Government convened the second Pancreas Cancer Summit in 2021 to identify unwarranted variation in care 2016-2019, and to assess trends compared with the first Summit 2017 (reporting 2011-2015). State-wide administrative data were assessed at population level in alignment with optimal care pathways across all stages of the cancer care continuum. METHODS: Data linkage performed by Centre for Victorian Data Linkage combined data from Victorian Cancer Registry with other administrative data sets including Victorian Admitted Episodes Dataset, Victorian Radiotherapy Minimum Data Set, Victorian Emergency Minimum Dataset and Victorian Death Index. A Cancer Service Performance Indicator audit was carried out providing an in-depth analysis of identified areas of interest. RESULTS: Of 3138 Victorians diagnosed with pancreas ductal adenocarcinoma 2016-2019, 63% were metastatic at diagnosis. One-year survival increased between time periods, from 29.7% overall 2011-2015 (59.1% for non-metastatic, and 15.1% metastatic) to 32.5% overall 2016-2019 (P < 0.001), 61.2% non-metastatic (P = 0.008), 15.7% metastatic (P = NS). A higher proportion of non-metastatic patients progressed to surgery (35% vs. 31%, P = 0.020), and more received neoadjuvant therapy (16% vs. 4%, P < 0.001). Postoperative mortality following pancreatectomy at 30 and 90 days remained low at 2%. Utilization of 5FU-based chemotherapy regimens increased between 2016 and 2020. Multidisciplinary Meeting (MDM) presentation was still below the 85% target (74%) as was supportive care screening (39%, target 80%). CONCLUSIONS: Surgical outcomes remain world-class and there has been an appropriate shift in chemotherapy administration towards neoadjuvant timing with increasing use of 5FU-based regimens. MDM presentation rates, supportive care and overall care coordination remain areas of deficiency.

BACKGROUND: Chemotherapy has in some series been linked with increased morbidity after a hepatectomy. Hepatic injuries may result from the treatment with chemotherapy, but can also be secondary to co-morbid diseases. The aim of the present study was to draw correlations between clinical features, treatment with chemotherapy and injury phenotypes and assess the impact of each upon perioperative morbidity. PATIENTS AND METHODS: Retrospective samples (n= 232) were scored grading steatosis, steatohepatitis and sinusoidal injury (SI). Clinical data were retrieved from medical records. Correlations were drawn between injury, clinical features and perioperative morbidity. RESULTS: Injury rates were 18%, 4% and 19% for steatosis, steatohepatitis and SI, respectively. High-grade steatosis was more common in patients with diabetes [odds ratio (OR) = 3.33, P= 0.01] and patients with a higher weight (OR/kg = 1.04, P= 0.02). Steatohepatitis was increased with metabolic syndrome (OR = 5.88, P= 0.02). Chemotherapy overall demonstrated a trend towards an approximately doubled risk of high-grade steatosis and steatohepatitis although not affecting SI. However, pre-operative chemotherapy was associated with an increased SI (OR = 2.18, P= 0.05). Operative morbidity was not increased with chemotherapy, but was increased with steatosis (OR = 2.38, P= 0.02). CONCLUSIONS: Diabetes and higher weight significantly increased the risk of steatosis, whereas metabolic syndrome significantly increased risk of steatohepatitis. The presence of high-grade steatosis increases perioperative morbidity, not administration of chemotherapy per se.

BACKGROUNDS: The impact of the SARS-CoV-2 virus (COVID-19) upon the delivery of surgical services in Australia has not been well characterized, other than restrictions to elective surgery due to government directive-related cancellations. Using emergency cholecystectomy as a representative operation, this study aimed to investigate the impact of COVID-19 on emergency general surgery in Australia in relation to in-hours versus after-hours operating. METHODS: A retrospective analysis was conducted of medical records for patients admitted with cholecystitis or biliary colic between 1 March 2019 and 28 February 2021 at Frankston Hospital, Australia. Patient demographics, admission data, imaging findings, operative and post-operative data were compared between pre-COVID-19 and COVID-19 periods. Variables were compared using the Wilcoxon-Mann-Whitney, Chi Squared or Fishers exact test. RESULTS: During the COVID-19 period, emergency cholecystectomy was performed for a greater proportion of patients presenting with cholecystitis or biliary colic (93.5% versus 77.7%, p < 0.01). Despite this, there was concomitant reduction in after-hours cholecystectomy from 14.4% to 7.5% (p = 0.04). Patients requiring after-hours surgery during the COVID-19 period had more features of sepsis (23% more tachypnoeic, 18% more hypotensive), and were more likely to have certain features of cholecystitis on imaging (45% more likely to have pericholecystic fluid). CONCLUSION: Following elective surgery cancellations during the COVID-19 period, an increase was seen in the proportion of patients presenting with gallstone disease who were managed with emergency cholecystectomy due to improved theatre access. Concurrently, there was a decrease in the requirement for surgery to be performed after-hours.
