Abstract
Rural surgery is most commonly provided by general surgeons to the 29% of people (7 million) living in rural Australia. The provision of rural general surgery to enable equitable and safe surgical care for rural Australians is a multifaceted issue concerning recruitment, training, retention, surgical procedures and surgical outcomes. Sustaining the rural general surgical workforce will be dependent upon growing an increased number of resident rural general surgeons, as well as changed models of care, with a need for ongoing review to track the outcomes of these changes. To increase recruitment, rural general surgical training must improve to be less stressful for trainees and to be incorporated alongside a rural-facing generalist curriculum. Rural general surgical outcomes (excluding some oncology conditions) achieve comparable results to metropolitan centres. Access to, and outcomes of, surgical oncology services continues to be inequitable for rural Australians and should be a major focus for improved service delivery.

Abstract
BACKGROUND Autosomal dominant polycystic kidney disease (ADPKD) is a common inherited condition, however its relationship with renal cell carcinoma (RCC) remains unclear. This paper aims to establish the prevalence of RCC and its subtypes amongst ADPKD patients. METHODS A database search was conducted to retrieve studies reporting RCC occurrence within ADPKD patients until July 2023. Key outcomes included number and subtype of RCC cases, and number of RCCs presenting incidentally. A random-effects meta-analysis was performed. RESULTS Our search yielded 569 articles, 16 met the inclusion criteria. Nephrectomy specimens from 1,147 ADPKD patients were identified. Of studies reporting per-kidney results (n = 13), 73 RCCs were detected amongst 1,493 kidneys, equating to a per-kidney prevalence of 4.3% (95% CI, 3.1 to 5.7, I2 = 15.7%). 75 ADPKD patients were found to have RCC (75/1147), resulting in a per-person prevalence of 5.7% (95% CI, 3.7 to 7.9, I2 = 40.3%) (n = 16). As 7 patients had bilateral disease, 82 RCCs were detected in total. Of these, 39 were clear cell RCC, 35 were papillary and 8 were other. As such, papillary RCCs made up 41.1% (95% CI, 25.9 to 56.9, I2 = 18.1%) of detected cancers. The majority of RCCs were detected incidentally (72.5% [95% CI, 43.7 to 95.1, I2 = 66.9%]). CONCLUSION ADPKD appears to be associated with the papillary RCC subtype. The clinical implications of these findings are unclear, however may become apparent as outcomes and life expectancy amongst APDKD patients improve.

Abstract
Current water footprint assessment methods make a meaningful assessment of livestock water consumption difficult as they are mainly static, thus poorly adaptable to understanding future water consumption and requirements. They lack the integration of fundamental ruminant nutrition and growth equations within a dynamic context that accounts for short- and long-term behaviour and time delays associated with economically significant beef-producing areas. The current study utilised the System Dynamics methodology to conceptualise a water footprint for beef cattle within a dynamic and mechanistic modelling framework. The problem of assessing the water footprint of beef cattle was articulated, and a dynamic hypothesis was formed to represent the Texas livestock water use system as the initial step in developing the Dynamic Beef Water Footprint model (DWFB). The dynamic hypothesis development resulted in three causal loop diagrams (CLD): cattle population, growth and nutrition, and the livestock water footprint, that captured the daily water footprint of beef (WFB). Simulations and sensitivity analysis from the hypothesised CLD structures indicated that the framework was able to capture the dynamic behaviour of the WFB system. These behaviours included key reinforcing and balancing feedback processes that drive the WFB. It is extremely difficult to identify policy interventions (i.e., management strategies) for complex systems, like the U.S. beef cattle system, because there are many actors (i.e., cow-calf, stocker, feedlot) and interrelated variables that have delayed effects within and across the supply chain. Identification and understanding of feedback processes driving water use over time will help to overcome policy resistance for more sustainable beef production. Thus, the causal loops identified in the current study provide a system-level insight for the drivers of the WFB within and across each major segment of the beef supply chain to address freshwater concerns more adequately. Further, the nutrient scenarios and sensitivity analysis revealed that the high versus low nutrient composition of pasture, hay, and concentrates resulted in a significant difference in the WFB (2 669 L/kg boneless beef, P < 0.05). The WFB was sensitive to changes in nutrient composition and specific water demand (m3/t) for each production phase, not only phases with high levels of concentrate feed use. As models evolve, there is potential for the DWFB to integrate precision livestock data, further improving quantification of the WFB, precision water-efficient strategies, and selection of water-efficient livestock.

Abstract
OBJECTIVE(S) Life and limb threatening vascular emergencies often present to rural hospitals where only general surgery services are available. It is known that Australian rural general surgical centres encounter 10-20 emergency vascular surgery procedures annually. This study aimed to assess rural general surgeons' confidence managing emergent vascular procedures. SETTING, PARTICIPANTS AND DESIGN A survey was distributed to Australian rural general surgeons to determine their confidence (Yes/No) in performing emergent vascular procedures including limb revascularisation, revising arterio-venous (AV) fistulas, open repair of ruptured abdominal aortic aneurysm (AAA), superior mesenteric artery (SMA)/coeliac embolectomy, limb embolectomy, vascular access catheter insertion and limb amputation (digit, forefoot, below knee and above knee). Confidence level was compared with surgeon demographics and training. Variables were compared using univariate logistic regression. RESULTS Sixteen per cent (67/410) of all Australian rural general surgeons responded to the survey. Increased age, years since fellowship and training prior to 1995 (when separation of Australian vascular and general surgery occurred) were associated with greater confidence in limb revascularisation, revising AV fistulas, open repair of ruptured AAA, SMA/coeliac embolectomy, and limb embolectomy (p < 0.05). Surgeons who completed >6 months of vascular surgery training were more comfortable with SMA/coeliac embolectomy (49% vs. 17%, p = 0.01) and limb embolectomy (59% vs. 28%, p = 0.02). Confidence in performing limb amputation was similar across surgeon demographics and training (p > 0.05). CONCLUSION Recently graduated rural general surgeons do not feel confident in managing vascular emergencies. Additional vascular surgery training should be considered as part of general surgical training and rural general surgical fellowships.

Abstract
INTRODUCTION In the context of shortfalls in rural general surgeon supply, this research aims to explore why rural general surgical Fellows returned and remained after fellowship at a single rural centre in Victoria, Australia. Fellowship positions post achievement of Fellowship of the Australasian College of Surgeons are traditionally not funded by government because they currently fall outside the accredited rural training post funding provided by the federal government. This article aims to explore if fellowship positions can be an important part in sustaining the rural general surgery workforce. METHODS Semi-structured interviews were conducted with nine former general surgery Fellows from a single rural Australian institution. Interviews were recorded, transcribed, coded and themed to undertake analysis according to thematic analysis. RESULTS This research demonstrates that consultant rural general surgeons can be recruited from a fellowship year when emphasis is placed on: (1) creating a positive workplace culture with safe working hours, (2) ensuring diversification of the general surgical case mix, (3) facilitating opportunities for schooling and work for the surgeon's family, and (4) preferentially selecting for those who identify as rural general surgeons. Rural towns can effectively recruit general surgeons when families are supported with career and school opportunities, and the newly qualified surgeon can initially commit to a 12-month position so that opportunities can be assessed by the entire family unit. Fellowship positions (post completion of general surgical training) allow young surgeons to 'try before they buy' prior to moving to a rural area. CONCLUSION Ensuring a sustainable general surgical workforce in a rural community requires employee and surgical leadership to ensure a collaborative and progressive culture, which offers work diversity, supports the family lifestyle and petitions for selecting those who embody the rural general surgeon identity. Post-fellowship positions can enable young general surgeons to have exposure to the realities of a rural lifestyle, which is likely to have a positive effect on recruitment. Due to the return investment of the fellowship program, we propose that the federal government should look at funding post-fellowship positions to improve rural recruitment.

Abstract
Abstract
A home-use, therapeutic ultrasound device was safe and effective for treating vaginal dryness after 12 weeks, and effectiveness was maintained to 1 year. Therapeutic ultrasound could offer a new, nonhormone treatment option for postmenopausal women with vulvovaginal atrophy.
Objective
To evaluate safety and effectiveness of therapeutic ultrasound for treatment of postmenopausal vaginal dryness.
Methods
In a pilot study, postmenopausal women with self-reported vaginal dryness were randomized (1:1) to double-blind ultrasound treatment (n = 21) or sham (n = 21) for 12 weeks. Primary effectiveness endpoint was change from baseline to week 12 in Vaginal Assessment Scale symptoms (dryness, soreness, irritation, dyspareunia). Secondary effectiveness endpoint was scoring of clinician-reported Vaginal Health Index (elasticity, fluid, pH, mucosa, moisture). After 12 weeks, participants received open-label ultrasound treatment to 1 year. Safety endpoint was treatment-emergent adverse events.
Results
In the modified intent-to-treat population, women showed (mean ± standard error) reduction in Vaginal Assessment Scale with ultrasound treatment versus sham (n = 15, −0.5 ± 0.2 vs n = 15, −0.4 ± 0.3; P = 0.9) and improved Vaginal Health Index (n = 9, 2.7 ± 0.9 vs n = 9, 0.6 ± 1.4; P = 0.3). In the per-protocol analysis population, ultrasound treatment (n = 9) versus sham (n = 8) significantly reduced symptoms score (−0.6 ± 0.3 vs −0.0 ± 0.4; P = 0.05) and significantly improved Vaginal Health Index (2.7 ± 0.9 vs −0.4 ± 1.2; P = 0.03). Improvement in effectiveness endpoints were seen at 1 year compared with baseline. There were no differences in treatment-emergent adverse events between ultrasound treatment versus sham and no serious adverse events.
Conclusions
Home-use ultrasound was safe and effective for treating vaginal dryness after 12 weeks. Effectiveness was maintained to 1 year. Therapeutic ultrasound could offer a new, nonhormonal treatment option for postmenopausal women with vulvovaginal atrophy.

Abstract
BACKGROUND To assess the contemporary trends in the types and incidence of pelvic organ prolapse (POP) surgery in Australia after the removal of transvaginal mesh from the Australian market. METHODS This was a retrospective Australian cohort study utilizing three large Governmental databases covering all private and public POP procedures in Australia. All females ≥25 years old undergoing POP procedures between 2005 and 2021 were included. RESULTS From 2005-2006 to 2020-2021 there have been a total of 408 881 POP procedures in Australia. The total number of procedures peaked in 2005-2006 at 537.8 procedures per 100 000 age-standardized female population, decreasing by an average of 3.5% per year to 329.0 procedures per 100 000 in 2018-2019, an overall 38.8% decrease (P < 0.001). A sudden growth in private operative procedures was noted between 2019-2020 and 2020-2021, from 218.2 to 268.6 procedures per 100 000 population, a 23.1% increase (P < 0.001). Laparoscopic and abdominal POP repair has seen a 115.8% increase from 13.7 procedures to 29.6 per 100 000 between 2005-2006 and 2020-2021. Over the last 15 years, the most common age group to undergo a procedure has changed from the 55 to 64 years demographic to a later decade of 65 to 74 years. CONCLUSION Over the last 15 years, the total number of POP procedures performed has significantly decreased. There has however been a recent rise in interventions seen in the private sector and the utilization of laparoscopic or abdominal POP repair has increased, which has implications for procedural credentialing to ensure patient safety.

Abstract
PURPOSE To review the evolution of female continence surgical practice in Australia over the last 20 years and observe whether vaginal mesh controversies impacted these trends. MATERIALS AND METHODS From January 2000 to December 2019, medicare benefit schedule codes for female continence procedures were identified and extracted for: mesh sling, fascial sling, bulking agent, female urethral prosthesis, colposuspension, and removal of sling. Population-adjusted incidences per 100,000 persons were calculated using publicly available demographic data. Three discrete phases were defined over the study time frame for analysis: 2000-2006; 2006-2017, and 2017-2019. Interrupted time-series analyses were conducted to assess for impact on incidence at 2006 and 2017. RESULTS There were 119,832 continence procedures performed in Australia from 2000 to 2019, with the mid-urethral sling (MUS) the most common (72%). The majority of mesh (n = 63,668, 73%) and fascial sling (n = 1864, 70%) procedures were in women aged < 65 years. Rates of mesh-related procedures steeply declined after 2017 (initial change: -21 cases per 100,000; subsequent rate change: -12 per 100,000, p < 0.001). Non-mesh related/bulking agents increased from + 0.34 during 2006-2017 to + 2.1 per 100,000 after 2017 (p < 0.001). No significant change in mesh extraction was observed over 2006-2017 (+ 0.06 per 100,000, p = 0.192). There was a significant increase in mesh extraction procedures after 2017 (0.83 per 100,000, p < 0.001). CONCLUSION Worldwide, controversy surrounding vaginal mesh had a significant impact on Australian continence surgery trends. The most standout trends were observed after the 2017 Australian class-action lawsuit and Senate Inquiry.

Abstract
OBJECTIVE This study aims to appraise and summarize consistent recommendations from clinical practice guidelines (CPGs) for identification and management of frailty to maintain and improve functional independence of elderly population. METHODS A systematic search of Ovid MEDLINE, Embase, PubMed, PsycINFO, and CINAHL electronic databases using database-specific search terms in two broad areas "guidelines" and "frailty", and a manual search of websites with the key phrase "frailty guideline" was performed. The inclusion criteria included CPGs focusing on identifying and managing frailty in population >65 years old, published in English since January 2010. Three reviewers independently assessed guideline quality using the AGREE II instrument. Data extraction was performed, followed by compilation and comparison of all recommendations to identify the key consistent recommendations. RESULTS Six CPGs met the inclusion criteria; however, only three CPGs had high methodological quality in accordance with AGREE II appraisal. The average AGREE II scores of all six CPGs were: 84.5%, 68%, 46.5%, 81.5%, 56.3%, and 60.2% for domains 1-6 (scope and purpose, stakeholder involvement, rigour of development, clarity of presentation, applicability, and editorial independence) respectively. A total of 54 recommendations were identified, with 12 key recommendations suggested frequently by the CPGs. CONCLUSION The AGREE II instrument identified strengths and weaknesses of the CPGs, but failed to assess clinical implications and feasibility of the guidelines. Further research is needed to improve clinical relevance of CPGs in the identification and management of frailty. The feasibility in implementing these guidelines with regards to cost-effectiveness of frailty screening warrants further investigation.

Abstract
OBJECTIVES To examine available data relating to the surgical management of stress urinary incontinence (SUI) in Australia before, during and after a well-publicized Senate Inquiry into transvaginal mesh use and to consider outcomes in the context of global guideline changes. PATIENTS AND METHODS The annual number of surgical procedures for the management of SUI by procedure type and age group for the years 2008/2009-2017/2018 was obtained from the Australian Government Department of Human Services database using Medicare Benefits Schedule item numbers. The data extracted were limited to women aged 25 years and older. These data were used to calculate age-specific and age-standardized rates, so as to accurately analyse trends in the usage of different procedures. Hospital Episode Statistics for mid-urethral sling (MUS) insertions were obtained for England's National Health Service from the Health and Social Care Information Centre for the years 2008/2009-2016/2017. These data were also used to calculate annual age-standardized rates for comparison purposes. RESULTS Rates declined for most SUI procedures over time (MUS, colposuspension, fascial slings) except for urethral bulking agents. The absolute number of MUSs implanted in 2008/2009 was 5729, which decreased to 3127 in the 2017/2018 financial year. Over the decade, the annual rate for MUS implantation per 100 000 population halved from 78 to 36. Over this same period, the rate of usage of bulking agents doubled, although represented a low volume of procedures (overall numbers increased from 304 to 698, representing an increase from four to eight procedures per 100 000 population). The age-specific peak rate for MUS and Burch colposuspension changed over the decade from 55-64 years to 65-74 years, suggesting that women are deferring surgical treatment until later in life. Over the last decade, the total number of surgical procedures performed in Australia to treat SUI has decreased markedly from 6812 to 4279. This represents a decrease in the annual rate per 100 000 population from 93 to 49. CONCLUSIONS There are clear changes evident for SUI management in the past decade in Australia, including an overall decline in operative numbers, which correlate with international advisory notifications and local investigations. The results of the Australian Senate inquiry, including removal of single-incision mini-slings, greater availability of patient resources, and greater regulation of SUI procedures, will probably have ongoing effects. Surgeons need to ensure that sufficient training and patient education continue in order to maintain appropriate access to treatment of SUI in the future.

Abstract
Background Multiparametric magnetic resonance imaging (mpMRI) has shown promise to improve detection of prostate cancer over conventional methods. However, most studies do not describe whether the location of mpMRI lesions match that of cancer found at biopsy, which may lead to an overestimation of accuracy. Objective To quantitate the effect of mapping locations of mpMRI lesions to locations of positive biopsy cores on the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of mpMRI. Design setting and participant We retrospectively identified patients having mpMRI of the prostate preceding prostate biopsy at three centres from 2013 to 2016. Men with targetable lesions on imaging underwent directed biopsy in addition to systematic biopsy. We correlated locations of positive mpMRI lesions with those of positive biopsy cores, defining a match when both were in the same sector of the prostate. We defined positive mpMRI as Prostate Imaging Reporting and Data System (PI-RADS) score ≥4 and significant cancer at biopsy as grade group ≥2. Outcome measurements and statistical analysis Sensitivity, specificity, PPV, and NPV were calculated with and without location matching. Results and limitations Of 446 patients, 247 (55.4%) had positive mpMRI and 232 (52.0%) had significant cancer at biopsy. Sensitivity and NPV for detecting significant cancer with location matching (both 63.4%) were decreased compared with those without location matching (77.6% and 73.9%, respectively). Of the 85 significant cancers not detected by mpMRI, most were of grade group 2 (64.7%, 55/85). Conclusions We report a 10-15% decrease in sensitivity and NPV when location matching was used to detect significant prostate cancer by mpMRI. False negative mpMRI remains an issue, highlighting the continued need for biopsy and for improving the standards around imaging quality and reporting. Patient summary The true accuracy of multiparametric magnetic resonance imaging (mpMRI) must be determined to interpret results and better counsel patients. We mapped the location of positive mpMRI lesions to where cancer was found at biopsy and found, when compared with matching to cancer anywhere in the prostate, that the accuracy of mpMRI decreased by 10-15%.

Abstract
BACKGROUND Patients with recurrent oropharyngeal cancer often require extensive salvage surgery. For patients with clinically N0 necks, the indication for concurrent neck dissection remains unclear. This study aimed to determine predictors, prevalence, and distribution of nodal disease in patients treated with salvage oropharyngectomy. METHODS In a case series with data collection at a single tertiary academic National Cancer Institute (NCI)-designated comprehensive cancer center, this study analyzed patients treated with prior radiation or chemoradiation who had persistent, recurrent, or second primary squamous cell carcinoma of the oropharynx requiring oropharyngeal resection between 1998 and 2017 (n = 95). Clinical and oncologic characteristics and treatment outcomes were collected, and statistical analyses were performed. RESULTS The overall rate of nodal positivity was 21% (24/95), and the rate of occult nodal disease was 6% (4/65). Ipsilateral and contralateral level 2 were the most common areas harboring positive nodes. Bivariate analysis showed female sex (p = 0.01), initial overall stage (p = 0.02), and N status (p = 0.03), as well as recurrent overall and T stage (p = 0.05) to be predictors of nodal disease. In the multivariate analysis, recurrent T stage continued to be significantly predictive of pathologic nodal disease. Both computed tomography (CT) and positron emission tomography-CT were moderately accurate in predicting nodal disease in the salvage setting (area under the curve, 0.79 and 0.80, respectively). CONCLUSION Occult nodal disease is observed in few patients undergoing salvage oropharyngeal resection. This study identified factors predictive of nodal disease in patients undergoing salvage oropharyngectomy and appropriate diagnostic tests in this setting.

Abstract
OBJECTIVE There are variable reports of risk of concordance for progression to islet autoantibodies and type 1 diabetes in identical twins after one twin is diagnosed. We examined development of positive autoantibodies and type 1 diabetes and the effects of genetic factors and common environment on autoantibody positivity in identical twins, nonidentical twins, and full siblings. RESEARCH DESIGN AND METHODS Subjects from the TrialNet Pathway to Prevention Study (N = 48,026) were screened from 2004 to 2015 for islet autoantibodies (GAD antibody [GADA], insulinoma-associated antigen 2 [IA-2A], and autoantibodies against insulin [IAA]). Of these subjects, 17,226 (157 identical twins, 283 nonidentical twins, and 16,786 full siblings) were followed for autoantibody positivity or type 1 diabetes for a median of 2.1 years. RESULTS At screening, identical twins were more likely to have positive GADA, IA-2A, and IAA than nonidentical twins or full siblings (all P < 0.0001). Younger age, male sex, and genetic factors were significant factors for expression of IA-2A, IAA, one or more positive autoantibodies, and two or more positive autoantibodies (all P ≤ 0.03). Initially autoantibody-positive identical twins had a 69% risk of diabetes by 3 years compared with 1.5% for initially autoantibody-negative identical twins. In nonidentical twins, type 1 diabetes risk by 3 years was 72% for initially multiple autoantibody-positive, 13% for single autoantibody-positive, and 0% for initially autoantibody-negative nonidentical twins. Full siblings had a 3-year type 1 diabetes risk of 47% for multiple autoantibody-positive, 12% for single autoantibody-positive, and 0.5% for initially autoantibody-negative subjects. CONCLUSIONS Risk of type 1 diabetes at 3 years is high for initially multiple and single autoantibody-positive identical twins and multiple autoantibody-positive nonidentical twins. Genetic predisposition, age, and male sex are significant risk factors for development of positive autoantibodies in twins.

Abstract
Aims In recent years it has been recognised that person-centred care can lead to better outcomes for patients and a reduced burden on healthcare systems. The aim of this study was to explore what really matters to members of the public when they visit a GP in Ireland. Methods This qualitative study used a structured interview methodology with one question; “What really matters to you when you go to see a GP?” Results were analysed using an integrated approach, involving both inductive and deductive methods. Results Responses from the 10 study participants were subdivided into two overarching themes: the General Practitioner as a person and the General Practice as a service. Personality (open, approachable, personable, trusted, interested) and service (time, cost, convenience, personal relationship) traits matter to patients. Conclusion Patients must be facilitated and encouraged to voice what really matters to them in order to inform truly person-centred healthcare improvement.

Abstract
The U.S. Food and Drug Administration requires food processors to implement and validate processes that will result in significantly minimizing or preventing the occurrence of hazards that are reasonably foreseeable in food production. During production of fresh-cut leafy vegetables, microbial contamination that may be present on the product can spread throughout the production batch when the product is washed, thus increasing the risk of illnesses. The use of antimicrobials in the wash water is a critical step in preventing such water-mediated cross-contamination; however, many factors can affect antimicrobial efficacy in the production of fresh-cut leafy vegetables, and the procedures for validating this key preventive control have not been articulated. Producers may consider three options for validating antimicrobial washing as a preventive control for cross-contamination. Option 1 involves the use of a surrogate for the microbial hazard and the demonstration that cross-contamination is prevented by the antimicrobial wash. Option 2 involves the use of antimicrobial sensors and the demonstration that a critical antimicrobial level is maintained during worst-case operating conditions. Option 3 validates the placement of the sensors in the processing equipment with the demonstration that a critical antimicrobial level is maintained at all locations, regardless of operating conditions. These validation options developed for fresh-cut leafy vegetables may serve as examples for validating processes that prevent cross-contamination during washing of other fresh produce commodities.

Abstract
In the ongoing evolution of a categorization system for endoleak, the authors propose the term endotension to define persistent or recurrent pressurization of the aortic aneurysm sac after endovascular repair. Endotension is evidence that the aneurysm remains at risk of rupture and should, therefore, be considered an indication for secondary intervention. Management strategies and a grading system for endotension are offered.

Abstract
Purpose: To report the incidence of delayed complications following endovascular abdominal aortic aneurysm (AAA) repair and the relationship of these sequelae to morphological changes in the sac and endograft. Methods: Twenty-six AAA patients treated with Vanguard endografts had completed ≥1-year follow-up. Postoperative angiograms and spiral computed tomographic (CT) scans with 3-dimensional reconstruction were compared to the 1-year images to determine morphological changes in the aneurysm sac and the endograft. These changes were then related to complications occurring between 1 and 12 months postoperatively in the study group. Results: Comparison of angiograms uncovered endograft buckling in 18 (69%) patients and acutely angled or kinked endografts in 10 (38%). Measurements from the CT scans found that undistorted endografts had a mean change in sac length of +6.6 mm. Mean sac length change in buckled endografts was −3.1 mm, while kinked endografts displayed a mean change of −6.2 mm (p < 0.002, Student's t-test). Five (19%) patients, all with distorted endografts, demonstrated late (1 to 12 months) complications (4 endoleaks and 1 graft limb thrombosis) owing to component separation, distal stent migration, and acute angulation. No movement in the proximal stent was observed. Elongation of the endograft (flow line measurement) was observed in one tube graft only. Conclusions: In this study, longitudinal shrinkage of the sac following endovascular aortic aneurysm repair led to buckling or kinking of the endograft within 1 year in 69% of patients. This appears to be an important source of delayed complications.

Abstract
OBJECTIVE Lower limb ulcers that are resistant to standard forms of treatment place a significant burden on both patients and health services. There is no widely agreed definition of a recalcitrant ulcer but failure to heal following 6-12 months of focused treatment would identify a small group of patients with highly resistant ulceration. We describe a series of patients with recalcitrant ulceration for which immunosuppressive agents have been used. METHODS This is a case series of 13 patients who underwent immunomodulation therapy for lower limb ulcers at a tertiary referral university hospital. Regimens of immunomodulation used mainly ciclosporin and/or cyclophosphamide, with concurrent antibiotic therapy. Case notes and computer systems were analysed by two reviewers. A patient was deemed to have a success if their ulcer fully healed while on immunomodulation therapy. RESULTS Over a period of eight years, from 2004-2012, 13 patients underwent immunomodulation therapy. Among these patients there were 18 ulcerated limbs. Ulcer healing occurred in 10 limbs out of 18 (55.6%) and full healing occurred in six patients (46.2%). Ulcers were present for a median of five years (range 2-40 years), with a median diameter of 7.5 cm (range 4-18 cm) before treatment. CONCLUSION Treatment of truly recalcitrant ulceration can be very frustrating for both the patient and physician, with poor success from more standard forms of treatment. We report experience with immunomodulation therapy that suggests there may be benefit from using this treatment in a subset of patients with this debilitating disease.

Abstract
OBJECTIVE To determine whether patients from regional areas undergoing surgery for kidney cancer present with more advanced disease as a result of geographic isolation. PATIENTS AND METHODS Retrospective analysis of 221 patients undergoing surgery for renal cell carcinoma (RCC) from January 2004 to June 2012, from both a metropolitan centre and a large inner regional hospital. Data was collected on age, gender, presentation (incidental or symptomatic), clinical stage and pathological features. The Australian Standard Geographical Classification-Remoteness Area (ASGC-RA) is a system developed to allow quantitative comparisons between metropolitan and rural Australia. A score was assigned to each patient based on their location of residence at the time of surgery: metropolitan, RA1; inner regional, RA2; outer regional, RA3. Statistical significance was specified as P < 0.05 on Pearson's chi-square tests. RESULTS Patients in each ASGC-RA group did not differ significantly in age, sex or mode of presentation. Pathological T stage on presentation increased with increasing ASGC-RA and thus distance from tertiary centres (P = 0.004). The proportion of patients with ≥T3 disease rose from 30% of RA1 to 73% of RA3 patients (P = 0.016) treated at our tertiary centre. Similarly, our regional centre had a larger proportion of patients presenting with ≥T3 disease from RA3 (31% vs 5%, P = 0.003). When the 221 patients with RCC were analysed as a group, clinical T stage was significantly associated with ASGC-RA (P < 0.001), symptomatic presentation (P < 0.001), N stage (P < 0.001), M stage (P < 0.001) and Fuhrman grade (P < 0.001). CONCLUSIONS Our data quantifies the detrimental effect of physical distance on the health outcomes of regional Australians with kidney cancer. Australia's unique geography and rural culture may preclude any attempts to centralise cancer care to specialised metropolitan units, as has occurred in other countries.
