The heart of the matter: secretory pheochromocytoma presenting as recurrent biventricular heart failure (Takotsubo cardiomyopathy).

Takotsubo's syndrome (TS) is an acute, transient cardiomyopathy occurring secondary to physical or emotional stressors through catecholamine excess. Secretory pheochromocytomas have been previously implicated in cases of TS (PTS), however, often present atypically, are associated with reoccurrence, and have higher rates of complications. We describe the case of a 70-year-old female who presented central chest pain, hypotension and electrocardiogram changes on a background of a 6-month prior episode of resolved Takotsubo's with unknown cause. After progressing to cardiogenic shock with biventricular failure, computerized tomography coronary aortogram revealed an incidental adrenal mass, later proven to be a secretory pheochromocytoma on biochemistry and subsequent histology. PTS has been associated with recurrence and rarely presents as cardiogenic shock. This case highlights the complexity of TS presentations and complications and the diagnostic delays that may occur in PTS.

A pancreatic mass and extreme elevation of CA 19-9: a benign masquerade of cholangiocarcinoma.

Carbohydrate antigen 19-9 (CA 19-9) is a specific tumour marker for pancreato-biliary malignancy. Immunoglobulin G4-related disease (IgG4-RD) is an immune-mediated condition in which IgG4 deposits infiltrate various organs, including the biliary tract manifesting IgG4 sclerosing cholangitis and pseudotumours. An 83-year-old woman presented with severe obstructive jaundice, weight loss and an extreme elevation of CA 19-9 level of 3295 kU/L. Magnetic resonance cholangiopancreatography (MRCP) revealed a pancreatic mass amputating the biliary tree. Liver function tests revealed a cholestatic pattern and severe hyperbilirubinaemia (289umol/L). IgG4 level was found to be high at 7.97 g/L. After treatment with high-dose corticosteroids, repeat MRCP 2 months later revealed disappearance of the pancreatic mass. There was also normalization of the bilirubin and a dramatic decrease of CA 19-9. This case reports the highest published benign elevation of Ca19.9 level in the setting of IgG4 disease. Differentiation between cholangiocarcinoma and IgG4-RD is important, as the treatment is vastly different.

The Abdominal Re-Approximation Anchor device (ABRA®) has the potential to be useful in both emergency and elective dynamic temporary fascial closure.

BACKGROUND: The management of an open abdomen (OA) remains an evolving field because of its relative rarity. Many techniques to achieve temporary abdominal closure exist, but often require multiple returns to the operating theatre and usually do not address the issue of lateral fascial retraction and do not achieve primary fascial closure (PFC). The ensuing incisional hernias result in a significant surgical challenge affecting both the physical and mental health of the patient. We describe our experience with the Abdominal Re-approximation Anchor (ABRA) device, which addresses some of these issues. METHODS: The records of patients with an OA managed by a single surgeon using the ABRA device at Princess Alexandra Hospital, Queensland, Australia, between December 2014 and April 2020 were analysed retrospectively. RESULTS: Six patients with OA were managed with the ABRA. All patients required an OA for the ramification of intraabdominal sepsis. Three patients were managed with the ABRA device electively and three in the acute setting. 100% of patients achieved PFC. Average follow-up was 40 months with three developing incisional hernias that were subsequently repaired. CONCLUSION: The OA in critically ill surgical patients remains one of the most challenging problems in general surgery. The ABRA device is simple to use and has shown positive outcomes in both the acute and elective setting. Our use has resulted in 100% PFC, which demonstrates that the ABRA device is an important tool for the general surgeon in managing these complex cases.
