RESUMEN
BACKGROUND AND OBJECTIVES: There is limited evidence to guide the management of patients with oligometastatic anal squamous cell carcinoma (SCC). We aimed to address this question by reporting the outcome of SCC patients who were treated with organ-directed therapies at two large cancer centers. METHODS: Patients with advanced anal SCC who were treated with surgery, stereotactic radiotherapy, or radiofrequency ablation (RFA) with a curative intent from 2008 to 2017 were retrospectively identified from the institutional electronic patient records. RESULTS: Eight patients with liver or lung metastases met the study inclusion criteria. Seven were treated with surgery while one received RFA and radiotherapy. Median progression-free survival was 5 months (range, 4-39). Three patients underwent repeat organ-directed treatment upon failure of the initial surgery with no evidence of further recurrent disease at the last follow-up. Median overall survival from the time of the first organ-directed therapy was 31 months (range, 11-96) with two out of eight patients being alive and disease-free at 5 years. CONCLUSIONS: Our study confirms that consideration should be given to the adoption of a multidisciplinary treatment approach in carefully selected, oligometastatic anal SCC patients as organ-directed therapies may offer the chance of achieving a relatively long disease control.

BACKGROUND: The Royal Australasian College of Surgeons awards scholarships to surgeons, surgical trainees and recipients focused on developing their clinical knowledge and improving outcomes for patients. A bibliometric analysis of research scholarship recipients publications and h-index scores was conducted to understand the benefits of receiving these scholarships. METHODS: A bibliometric analysis of Royal Australasian College of Surgeons scholarship recipients in 2015 was performed using Open Researcher and Contributor ID (ORCID), Scopus, Google Scholar, ResearchGate, LinkedIn and PubMed to identify the number of publications, h-index scores, field-weighted citation impact and the relative citation ratio. RESULTS: Nineteen research scholarship recipients authored 842 publications, with 491 (58%) published after completion of their scholarship. Seven recipients published 50% or more of their articles in the 5 years since completion. Five recipients have each published more than 45 articles since 2015. H-index scores varied between Scopus and Google Scholar (overall range: 4-34). Scopus identified the most publications, followed by ResearchGate. Determining publication numbers for recipients was problematic due to self-reporting in some databases (i.e. Google Scholar, ResearchGate), variations in author names (i.e. maiden to married name), duplication of publications and the inclusion of supplementary material (i.e. extra tables) in self-reporting databases. Field-weighted citation impact and relative citation ratio values exceeded 1 on 12 occasions demonstrating recipients are more cited than the global average. CONCLUSION: Continuous tracking of publication rates and h-index scores of scholarship recipients demonstrates recipients' continuing interest in advancing and disseminating medical knowledge to improve patient outcomes. The 2015 scholarship recipients publication numbers continued to increase after their scholarship tenure.

BACKGROUND: Many hospitals across Australia and New Zealand have implemented acute care surgery (ACS) models over the past decade, often with improved outcomes such as reductions in wait time to surgery, complications and length of stay. The aim of this study was to evaluate the outcomes of patients who underwent non-elective appendicectomy and cholecystectomy and compare these with the results observed shortly after the implementation of an ACS model at our institution 10 years earlier. METHODS: A retrospective review of contemporary patients who underwent non-elective appendicectomy and cholecystectomy compared with historical data was performed. Primary outcomes were wait time to surgery, surgical complications and length of stay. RESULTS: In the contemporary cohort, 263 patients underwent non-elective appendicectomy over a 1-year period compared with 226 patients in the historical cohort. The median wait time to surgery had increased (17.7 versus 9.6 h, P < 0.001). There was no significant difference in a composite end-point of complications and readmissions (8.0% versus 9.3%, P = 0.61). The length of stay was unchanged. There was greater use of preoperative imaging and reduced overnight operating. For non-elective cholecystectomies, 132 patients underwent this procedure in the contemporary cohort over a 2-year period compared with 115 patients in the historical cohort. There were no significant differences in wait time to surgery (2 versus 1 day, P = 0.13) or complications (9.8% versus 8.7%, P = 0.75). The length of stay was unchanged. CONCLUSION: The majority of improvements seen shortly following the implementation of an ACS model have been sustained after 10 years.

In the last decade, emergency general surgery (EGS) in Australia and New Zealand has seen a transition from the traditional on-call system to the acute surgical unit (ASU) model. The importance and growing demand for EGS has resulted in the implementation of the General Surgeons Australia's 12-point plan for emergency surgery. Since its release, the 12-point plan has been used as a benchmark of a well-functioning ASU, both locally and abroad. This study aims to provide a descriptive review on the relevance of the 12-point plan to the ASU model and review the current evidence to support this framework. The review concludes that the establishment of the ASU model has met the aims set out by the Royal Australasian College of Surgeons for EGS. The 12-point plan is relevant and has good evidence to support its framework.

Small bowel obstruction is a common and significant surgical presentation. Approximately 30% of presentations will require surgery during admission. The great challenge of adhesive small bowel obstruction (ASBO) management is the early detection of silent intestinal ischaemia in patients initially deemed suitable for conservative therapy. Recent literature emphasizes the effectiveness of computed tomography enterography and water-soluble contrast studies in the management of ASBO. Low-volume undiluted water-soluble contrast has been shown to have both triage and therapeutic value in the management of ASBO. Their use has been demonstrated to reduce the need for surgery to below 20%. There has also been growing interest in clinicoradiological algorithms which aim to predict ischaemia early in the course of presentation. The aim of this review is to summarize the latest evidence and clarify previous uncertainties, specifically regarding the duration of conservative treatment, timing of contrast studies and the reliability of predictive algorithms. Based on this latest evidence, we have formulated a management protocol which aims to integrate these latest developments and formalize a strategy for best management in ASBO.

BACKGROUND: With poor cure rates in gastric cancer using surgery alone, the safety, efficacy and feasibility of preoperative and postoperative chemotherapy was investigated. METHODS: Patients with advanced but operable gastric or cardio-oesophageal adenocarcinoma were staged using endoscopy, computed tomography scan and laparoscopy. If considered potentially resectable, they received chemotherapy (epirubicin, cisplatin and 5-fluorouracil) for 9 weeks before and after surgery. RESULTS: Of 59 participants entered, two were found to have metastatic disease and were excluded from the analysis. Of the participants, 10 were women and 47 men; their median age was 58 years (range 27-83 years) and median performance status 0 (range 0-1). Two of the 57 participants commencing chemotherapy did not undergo surgery (one sudden death, one new liver metastases). Grade 3 and 4 preoperative and postoperative toxicity rates were, respectively, neutropenia 22 and 18%, emesis 12 and 14% and other non-haematological toxicity <10 and <10%. Of the 55 who underwent surgery, 40 had apparently curative resections (clear or positive microscopic margins), 2 died after surgery (anastomotic leak, sepsis) and 16 had postoperative complications. Of these, 27 participants commenced postoperative chemotherapy and 21 completed it. Median progression-free survival and overall survival were 19.6 and 22 months, respectively. CONCLUSION: Epirubicin, cisplatin and protracted venous infusion of 5-fluorouracil chemotherapy was well-tolerated in the preoperative setting and did not appear to increase complication rates of surgery for advanced and operable stomach cancer. These findings demonstrate the feasibility of this strategy in the Australasian clinical setting and are in keeping with the results of a recently reported randomized trial, which demonstrated a significant survival advantage using this chemotherapy regimen.

BACKGROUND: An acute care surgery (ACS) model was introduced to manage emergency surgical presentations efficiently. The aim of this study was to evaluate the impact of patient handover in an ACS model on the outcomes of adhesive small bowel obstruction (SBO). METHODS: A retrospective study was performed on patients who were admitted with adhesive SBO at Prince of Wales Hospital. The cohort consisted of all patients treated by the ACS team from its introduction in September 2005 to February 2011. Patients in the ACS cohort were divided into two groups: those whose care was handed over to another surgeon and those whose care was not. These groups of patients were compared with a random sample of 50 patients in the pre-ACS period. RESULTS: In the ACS period, there was no significant difference in complication rates or length of hospital stay in those who were not handed over and those who were. A significantly higher proportion of operations took place during the day for the group who had been handed over (72.7% versus 36.7%; P = 0.005). There were no significant differences in complication rates or length of hospital stay in the pre-ACS and ACS period. CONCLUSION: Management under an ACS team does not increase adverse outcomes for adhesive SBO. Patients can be safely handed over within an ACS framework. Other members of the ACS team may help facilitate continuity of care.
