Background: Pancreatoduodenectomy (PD) is a highly complex, invasive, and costly surgical procedure. Limited evidence on the PD volume-cost relationship in countries with a low population density exists. This study aimed to investigate this issue in Australia.

Methods: This retrospective cohort study included pancreatic cancer patients who had a PD at any public hospital in New South Wales, Australia between 2016 and 2019. The primary outcome was the total hospital cost during PD admission (not including patient financial burden). Study hospitals were grouped into low-volume hospitals (LVHs; <10 PDs per annum) or high-volume hospitals (HVHs). Multivariable modelling was applied to examine the association between volume and cost.

Results: Of 443 PDs, the median total hospital cost per patient at HVHs was AU$55398; significantly lower than that at LVHs (AU$62859; P = 0.001). After adjusting for available patient and clinical factors, the total cost per patient at LVHs was 22% higher than that of HVHs (adjusted estimate: 1.22, 95% CI: 1.08-1.37; P = 0.002). Similar patterns were found in three main cost components: 24% higher employee cost at LVHs than at HVHs (1.24, 95% CI: 1.10-1.41; P < 0.001), 15% higher operating cost (1.15, 95% CI: 1.00-1.31; P = 0.047), and 31% higher other costs (1.31, 95% CI: 1.12-1.53; P < 0.001).

Conclusion: Performance of PDs at HVHs was associated with substantially lower hospital costs. Our findings demonstrate the likely economic benefit of centralizing PDs in countries with a relatively low population density. Future studies should investigate related patient financial burdens.

Background: Currently pathways to practice in endocrine surgery vary based on location and surgical training programme. International data highlights the impact of surgeon volume on outcomes, and the importance of understanding the learning curve in developing minimum training competencies. This study aims to explore how surgeons obtain competence in endocrine surgery in Australia and New Zealand, and perceptions around competence and scope of practice.

Methods: A web-based survey was distributed to fellows practicing endocrine surgery. Participants were invited to complete a semi-structured interview to explore key themes around competence. Thematic analysis was performed.

Results: Responses from 87 surgeons, with 30% practicing primarily in a regional or rural area, showed 94% emphasized post-fellowship training to be competent in endocrine surgery. Median primary operator procedural volume learning curves were 50 thyroid, 30 parathyroid and 20 laparoscopic adrenalectomy procedures. Semi-structured interviews with 12 participants identified four major themes: (1) learning opportunities during general surgical education and training programmes alone are insufficient for consultant-level competence; (2) the importance of sufficient training to develop clinical decision-making, insight and judgement to appropriately select patients in the management of endocrine disease; (3) expected standards of clinical and technical performance are independent of practice location or context; (4) the importance of multi-disciplinary teams for complex cases including advanced cancers.

Conclusions: Practicing endocrine surgeons acknowledge formal fellowship training is required to achieve competence across technical and non-technical domains. The definition of competence and expectations regarding technical outcomes are independent of practice location or context.

Background: This study determined, implemented, and assessed a nurse-led radical cystectomy follow-up protocol.

Methods: In 2021, an evidence-based risk-stratified protocol (non-urological cancers and benign [N-UC&B], low, or high risk) was developed from current guidelines, local and national expert opinion, and after formal discussion with the Urological Society of Australia and New Zealand (USANZ) Western Australia (WA) and Australia and New Zealand Urogenital and Prostate (ANZUP) Cancer Trials Group. Retrospective and prospective assessment of cystectomy follow-up occurred between 2015 and 2023. Patients received 'surgeon-led' follow-up March 2015 to August 2021, and 'nurse-led' follow-up August 2021 to April 2023. Adherence to follow-up, cost-analysis, and healthcare efficiency calculations were performed.

Results: Of 176 cystectomy patients, 159 (90.3%) were eligible for inclusion. Overall adherence to nurse-led follow-up was 78.6% compared to 43.4% in surgeon-led (P < 0.001). Adherence to nurse-led follow-up was higher in all risk categories (high-risk 79.1% vs. 43%, P < 0.001; low risk 75% vs. 52.3%, P = 0.110; N-UC&B 71% vs. 30%, P = 0.153). Nurse-led consultation saved $59.50 per consultation with overall cost savings of $179.50, $416.50, and $595 for the entire follow-up period for N-UC&B, low, and high-risk groups based on consultation alone. A total of 1072 appointments (536 h, $62 390.40) would have been saved if the surgeon-led cohort of patients were seen in nurse-led clinics.

Conclusion: Protocol driven nurse-led cystectomy follow-up demonstrates excellent adherence and may be more cost-effective than surgeon-led follow-up.

Background: Access to laparoscopic cholecystectomy is more limited for remote communities and Indigenous patients internationally. To date, studies exploring the incidence of gallstone disease and access to laparoscopic cholecystectomy in Australian regional communities are limited. This study examined the rates and outcomes of emergency laparoscopic cholecystectomy (EMLC) in Far North Queensland, specifically in Indigenous and remote populations.

Aims: We retrospectively examined all patients who underwent an EMLC at Cairns Hospital between 2016 and 2021.

Results: Over the study period, 634 EMLCs were undertaken. The average annual rate of 56 cases per 100 000 was considerably lower than national estimates. However, rates of EMLC were significantly higher in remote communities and Indigenous patients compared with the remaining cohort. Patients from remote communities were more likely to have pre-existing gallstone disease but were less likely to have been seen in a surgical outpatient clinic prior to admission. Despite this, surgical outcomes for EMLC were comparable to national and international standards.

Conclusion: This study highlights the challenges in surgical healthcare provision for gallstone disease in a regional centre. The requirement for EMLC disproportionately effects geographically isolated communities and Australian Indigenous people. Addressing the healthcare barriers to management of GD in regional Australia should be a priority.

Backgrounds: There is growing evidence on the benefits of integrated models of care between surgeons and physicians in non-orthopaedic surgery. We implemented a new General Surgery/General Medicine care model, for all emergency General Surgery patients aged 75 years and older. We compared rates of goals of care (GOC) documentation, hospital-acquired complications (HAC), mortality, and hospital length of stay (LOS).

Methods: This is a non-randomized trial, with data collected prospectively in phase 1 (2021-2022), where patients received the traditional standard of care (case-by-case referral to a General Physician), and in phase 2 (2022-2023) where patients received integrated care. Variables were compared between phase 1 and phase 2 using Generalized Linear Models (GLMs).

Results: Five hundred and forty-nine patients, 188 in phase 1 and 361 in phase 2, participated in the study. On univariate analysis, there was a significant increase in patients treated non-surgically in phase 2 (58.5% vs. 69.0%). Patients treated non-surgically had significantly shorter LOS, experienced less HACs (P < 0.001). Other variables did not significantly differ after implementation of the service. The multivariate GLM revealed a significant reduction in admissions with undocumented GOC in phase 2 (P = 0.037).

Conclusion: This study showed that an integrated care model resulted in a greater proportion of patients being treated non-surgically with a comparable rate of HAC and mortality, as well as better documentation of patients' GOC. As the number of older surgical patients will continue to rise, the call for such service to become standard of care in non-orthopaedic surgery is pressing.

Background: The clinical characteristics and management of late-onset chylothorax after lung cancer surgery remained unknown. Here we aimed to provide evidence on the management of late-onset chylothorax by analysis of several cases with the largest sample size.

Methods: We retrospectively collected clinical data of patients who developed late-onset chylothorax after lung cancer surgery and were re-admitted by a single surgeon in our center from 2016 to 2022. The clinical characteristics and management for these patients were analysed. The role of Hem-o-lok clipping after lymphadenectomy in preventing late-onset chylothorax was further explored by comparing the surgical outcomes between treated group and control group.

Result: A total of six patients who were re-admitted for late-onset chylothorax after lung cancer surgery were included for analysis. The mean age of them was 60.7 years old. The symptom of late-onset chylothorax was mainly dyspnea and cough and the diagnosis was all made by Sudan III staining between postoperative day 17 to 42. All patients were firstly treated with thoracocentesis and low-fat diet with intravenous nutrition. Four patients were successfully managed with low-fat diet and thoracocentesis, while the other two patients were further managed with pleurodesis with 50% glucose fluid solution. We found a significantly decreased risk of late-onset chylothorax in the treated group with improved procedure of applying Hem-o-lok clipping after lymphadenectomy than in the control group (0% versus 2.6%, P < 0.01).

Conclusion: Late-onset chylothorax after lung cancer surgery was a rare and negligible complication, which may usually be managed by non-surgical methods. Hem-o-lok clipping during lymphadenectomy seemed to be an effective method to prevent late-onset chylothorax after lung cancer surgery.

Background: The use of nomograms in predicting the prognosis of early-stage non-small cell lung cancer (NSCLC), particularly in elderly patients, is not widespread. A validated prognostic model specifically for NSCLC patients over 80 years old holds promising potential for clinical application in forecasting patient outcomes.

Methods: The prognostic value of various factors for NSCLC patients aged 80 and above was evaluated using data from the Surveillance, Epidemiology, and End Results (SEER) database (2010-2017). Kaplan-Meier (KM) curves, Cox proportional hazards regression models, and nomogram were utilized to evaluate the impact of each factor on cancer-specific survival (CSS).

Results: A cohort comprising 7045 individuals was selected for inclusion in the analysis. Through rigorous statistical analysis, 10 independent prognostic factors were identified and incorporated into the nomogram. The nomogram's receiver operating characteristic (ROC) curve area under the curve (AUC) was higher than that of the AJCC 7th edition TNM staging system's predicted CSS (0.744 versus 0.602), establishing the superior prognostic value of the nomogram.

Conclusions: We have successfully created a highly accurate and discriminative nomogram that enables oncologists to predict the survival outcome of each individual patient with I/II NSCLC who is 80 years or older.

Background: Day-case laparoscopic cholecystectomy (DCLC) is a useful tool for minimizing hospital admissions and prolonged presurgical wait times in suitable patient cohorts. There have been many international studies to support this finding and an increasing interest has grown in implementation in Australia. This review aims to provide clarity how to best implement this tool in gallbladder disease patient demographic.

Observations: This literature review evaluates studies on day-case cholecystectomy procedures, focusing on patient factors, procedural aspects, surgical morbidity, and systemic implications. It explores inclusion and exclusion criteria for day-case suitability, factors influencing same-day discharge, reasons for hospital admission, pain management, patient quality of life, patient satisfaction, and cost implications.

Conclusions: DCLC, when selected judiciously, is a safe alternative to overnight stay procedures for cholecystectomy with comparable surgical outcomes and patient satisfaction, affirming its viability. Strict patient selection criteria can aid in optimizing the successful implementation procedure, reducing unexpected admissions and readmissions and we have demonstrated useful criteria for guidance in establishing day-case laparoscopic cholecystectomy protocol at a hospital.

Background: Conservative parotidectomy for benign tumours reduces facial nerve palsy, without increasing local recurrence. We report a modified technique of partial parotidectomy and using a novel description of tumour position, explore relationships between tumour position and histological margins, facial nerve palsy and local recurrence.

Methods: A prospectively collected single surgeon parotidectomy database was analysed, including tumour location (superficial/deep lobe; central/peripheral) and outcomes. A partial parotidectomy identified the facial nerve and the proximal portion of its branches with a macroscopically clear resection margin. Mean follow up was 5.9 years for pleomorphic adenomas.

Results: Three hundred and three patients underwent parotidectomy; 257 (84.8%) were superficial and 46 (15.2%) deep lobe. Tumour position was recorded in 291: 236 (81.1%) were peripheral tumours and 55 (18.9%) central. Histological margin involvement was similar in central and peripheral tumours, both overall and for superficial and deep lobe tumours, but was commoner in central deep lobe tumours, (P = 0.003). Temporary partial facial nerve palsy occurred in 21 (6.9%), with one permanent partial nerve palsy (0.3%). Deep lobe tumours and total parotidectomy were associated with facial nerve palsy (P = 0.01). Facial nerve monitoring reduced the risk of palsy (P < 0.01). Local recurrence of pleomorphic adenomas was uncommon, occurring in 3 (2.0%) of 151 patients.

Conclusion: This series confirms the safety and adequacy of more conservative partial parotidectomy for benign tumours, highlighting most tumours are peripheral, but not more prone to histological margin involvement or local recurrence, and with routine intraoperative facial nerve monitoring, is achieved with low facial nerve palsy rates.
