Background The purpose of this study was to review the current management of gastro-oesophageal reflux disease (GORD), including treatment costs, safety profile and effectiveness. Methods A literature review was performed of randomized-controlled trials, systematic reviews, Cochrane reports and National/Societal guidelines of the medical, endoscopic and surgical management of GORD. Proton pump inhibitor (PPI) prescribing patterns and expenditure were reviewed in different countries, including Australia, Canada, New Zealand, UK and USA. Results Proton pump inhibitors (PPIs) are primarily indicated for control of GORD, Helicobacter pylori eradication (combined with antibiotics), preventing NSAID-induced gastrointestinal bleeding and treating peptic ulcer disease. There is widespread overprescribing of PPIs in Western and Eastern nations in terms of indication and duration, with substantial expense for national health providers. Despite a favourable short-term safety profile, there are observational associations of adverse effects with long-term PPIs. These include nutrient malabsorption, enteric infections and cardiovascular events. The prevalence of PPI use makes their long-term safety profile clinically relevant. Cost-benefit, symptom control and quality-of-life outcomes favour laparoscopic fundoplication rather than chronic PPI treatment. Laparoscopic fundoplication in long-term management of PPI-responsive GORD is supported by SAGES, NICE and ACG, and PPI-refractory GORD by AGA and SAGES guidelines. The importance of establishing a definitive diagnosis prior to invasive management is emphasized, especially in PPI-refractory heartburn. Conclusions We examined evidence-based guidelines for PPI prescribing and deprescribing in primary care and hospital settings and the need for PPI stewardship and education of health professionals. This narrative review presents the advantages and disadvantages of surgical, endoscopic and medical management of GORD, which may assist in shared decision making and treatment choice in individual patients. This paper was presented (GS020) at the 88th RACS Annual Scientific Conference, 6-10 May, 2019.

Background Perfusion mapping with indocyanine green angiography (ICGA) in breast reconstruction can change intraoperative plans and reduce the risk of flap necrosis. We evaluated the utility of ICGA in the decision to delay reconstruction postmastectomy and its predictive power for necrosis. Methods Single-institution retrospective study of implant-based breast reconstructions following mastectomy using ICGA from 2015 to 2021. A decision was made to proceed with immediate reconstruction or delay reconstruction based on clinical assessment and perfusion analysis. Incidence of complications in the immediate and delayed cohorts were assessed. Intraoperative ICGA perfusion values were correlated with postoperative outcomes to calculate diagnostic accuracy. Results Three hundred twenty breast reconstructions were performed. Two hundred fifty-nine of these underwent immediate reconstruction, while 61 underwent delayed reconstruction due to poor perfusion. Median time between mastectomy and delayed reconstruction was 7.3 days (range, 4–21 days). All 8 cases (3.1%) of necrosis were in the immediate cohort. Cases of necrosis had significantly lower intraoperative ICGA perfusion values compared to cases without necrosis (absolute values 13.1 versus 27.1 units, p = 0.017). Increasing our ICGA cut-off score for necrosis from 14 to 22 units would have increased sensitivity from 63 to 100% but reduced specificity from 70 to 48%. Conclusions Delayed breast reconstruction due to poor perfusion on ICGA resulted in no cases of necrosis. A higher ICGA cut-off score for predicting necrosis is more sensitive but less specific. ICGA is useful as a supplement rather than a substitute for clinical assessment in flap perfusion evaluation. Level of Evidence Level III, Risk / Diagnostic Study.

Case reportCholecystocutaneous fistula is a rare complication of untreated cholecystitis. We present a unique case of a cholecystocutaneous fistula draining via a parastomal hernia.

Cutaneous metastases of oesophageal adenocarcinoma are uncommon. Several different sites of metastases including skin and lip has been reported.  However, metastases to the scalp is an extremely rare event. We present a unique case of oesophageal adenocarcinoma metastasis to the scalp. Further, a discussion is offered on the mechanism of route of spread from the oesophagus to the scalp.

Subcutaneous emphysema is a frequent post-operative complication. Although many cardiorespiratory complications associated with subcutaneous emphysema has been described, skin rashes have not been described as a complication. We present a case of asymmetrical erythematous skin rash secondary to subcutaneous emphysema. To the best of our knowledge this association has not been reported before. It is important to recognise cutaneous changes such as skin rash as a potential complication of subcutaneous emphysema and avoid inappropriate management and prolonged hospital stay. complication.

Background: Indocyanine green angiography (ICGA) aims to reduce ischaemic complications by supplementing intraoperative perfusion assessment of mastectomy flaps. Learning curves for this technology have not been analysed. We evaluated changes in patient outcomes with increasing case volume after ICGA adoption in postmastectomy reconstruction. Methods: Single-institution retrospective analysis of 320 implant-based reconstructions following mastectomy using ICGA from 2015, when it was introduced, to 2021. Cases chronologically divided into tertiles and complications amongst groups evaluated. Trends in ischaemic complications plotted using weighted moving average. CUSUM analysis determined after how many cases plateau was reached. Number of ischaemic complications prior to plateau calculated with AUC analysis. Results: Ischaemic complications decreased over time (Group 1, 15.1%; Group 2, 11.2%; Group 3, 4.7%, P = 0.034). Cases of delayed reconstruction increased over time (Group 1, 6.6%; Group 2, 28%; Group 3, 22.4%; P < 0.001). Our institution reached plateau of 10% ischaemic complications after 160 cases. Mean incidence of ischaemic complications decreased from 16.9% during the first 160 cases to 3.8% after plateau was reached (P < 0.001). Eleven extra breasts (6.9%) experienced ischaemic complications, that may have been avoided if operated by surgeons after the first 160 cases. Conclusions: There was increased tendency towards a conservative approach of delaying reconstruction and decreased rates of ischaemic complications with increasing case volume after ICGA implementation. A significant number of cases were needed to reach plateau of minimal ischaemic complications. This data could encourage development of standardized protocols for this technology to shorten learning curves for improved patient outcomes.

Background Angioembolization is a useful therapeutic tool for lower gastrointestinal bleeding (LGIB) however is only available at centres with specialist interventional radiology departments. Delay in angioembolization of greater than 120–150 minutes is associated with higher rates of non‐therapeutic angioembolization. Methods This retrospective review analysed the impact of interhospital transfer on timing and success of angioembolization in adults with LGIB. Results Of the 121 patients who underwent CTMA at a peripheral hospital for LGIB, only 20.7% had positive CTMA (n = 25). Of the 24 patients who were transferred for the purpose of angioembolization, only five ultimately had successful embolisation (20.1%). Patients who had unsuccessful angioembolization had a significantly longer mean time from arrival at the tertiary hospital to angioembolization compared to patients who had successful angioembolization (mean 375 versus 175 min, P = 0.001). There was no association of patient haemodynamics, use of anticoagulant or antiplatelet therapy, and transfusion requirement with success of angioembolization. Conclusion Interhospital transfer is associated with delay in angioembolization. Delay after arrival at the receiving hospital is associated with unsuccessful angioembolization.
