Background: The coronavirus disease 2019 (COVID-19) crisis caused by the severe respiratory distress syndrome coronavirus 2 (SARS-CoV-2) rapidly led to a pandemic. While the majority of SARS-CoV-2-infected patients present with fever and respiratory symptoms, gastrointestinal symptoms may also occur. In addition, serious hepatic manifestations like cholangiopathy and liver failure have been described.

Patients and methods: We identified two critically ill patients suffering from SARS-CoV‑2 infection in our intensive care unit (ICU). In both patients, laboratory testing revealed elevated liver chemistries weeks after initial diagnosis with COVID-19.

Results: During repeated endoscopic retrograde cholangiopancreatography (ERCP) with cholangioscopy, a severely destructed biliary mucosa with ischemia and epithelial roughness was seen in both patients. Due to the prolonged course of COVID-19 and chronic liver damage with ongoing sepsis, both patients succumbed to the disease.

Conclusion: In our opinion, a COVID-19 infection can lead to development of cholangiopathy in critically ill patients. Cholangioscopy performed early can confirm the diagnosis of COVID-19-associated cholangioscopy.

Background: Laparoscopic cholecystectomy is one of the most frequently performed operations in the United Kingdom, commonly due to symptomatic gallstones. Delay between diagnosis and definitive surgical intervention often leads to a significant readmission rate, growing financial burden and increased complexity of the ultimate surgical intervention. Resource reallocation and reduced operational capacity during the coronavirus disease 2019 (COVID-19) pandemic has led to an impending waiting list crisis.

Methods: In an attempt to address the backlog of cases, five intensive dedicated operating lists were allocated for laparoscopic cholecystectomies across a weekend in October 2020 at a single Trust. Prospective data were collected to include baseline demographics, operative procedure, 30-day post-operative outcomes and financial implications.

Results: A total of 21 cholecystectomies were performed in total, with a majority ASA 2 (American Society of Anaesthesiologists) for predominantly biliary colic indication. All were completed laparoscopically, with a 90.5% rate for complete resection. There were no reported on-table complications and 81.0% of patients discharged as a day case. Thirty day follow-up revealed a complication rate of 9.5%, with 2 patients requiring oral antibiotics for a superficial wound infection. The 30 day COVID-19 rate was 14.3%. Compared to completion on an average weekday list, the total weekend was estimated to have saved over £70,000 in overall costs.

Conclusion: Our study showed that weekend focused operating, with a caveat of careful patient selection and high-quality multidisciplinary working, can be a feasible solution to long waiting lists due to COVID-19 pandemic. It was safe, with avoidance of increased burden on emergency resources, and significantly increased theatre efficiency.

Background: Breast cancer may present with distinct cutaneous manifestations that may be paraneoplastic or secondary to direct skin infiltration, distant skin metastases, or dermal lymphatic tumor embolization (inflammatory breast carcinoma).

Case report: A 51-year-old Asian woman visited the emergency care department during the outbreak of COVID-19 in Northern Italy. About 6 months before, she had noted the onset of right breast swelling accompanied by skin redness and itching. She never consulted a physician, and, over time, the local skin condition progressed to a large scaly plaque covering the entire breast surface including the nipple. At presentation, abduction of the right upper limb was impaired due to severe shoulder pain. CT scan showed the presence of bilateral breast masses with necrotic and colliquative features, and multiple skeletal, nodal, pulmonary, and brain images suggestive of metastases. An ultrasound-guided core biopsy of the contralateral breast showed grade 2 non-special type infiltrating carcinoma. The patient was referred to the breast oncology unit and is currently being treated with aromatase inhibitors and chemotherapy.

Conclusion: The COVID-19 pandemic has disrupted the entire spectrum of oncological care including breast cancer. Hopefully, telemedicine will contribute to increase patients' confidence and will provide earlier diagnosis and treatment while minimizing the risk of contagion.

Background: The COVID-19 pandemic caused by the SARS-CoV‑2 virus has strongly affected the visceral and thoracic surgery department in southern Vorarlberg in Austria, which comprises two locations: the focus hospital in Feldkirch and the regional hospital in Bludenz.

Methods: The complete lockdown lasted 6 weeks (from March 16 to April 26, 2020), after which the hospital in Bludenz started day surgery again and in Feldkirch the capacity was slowly increased. We compared how oncological and acute operations differed during those 6 weeks to the 6 weeks before lockdown.

Results: Our findings show a clear increase in emergency operations for acute cholecystitis (+133%) and acute appendicitis (+157%). While the acute operations increased, some oncological operations decreased, which was especially apparent for oncological colorectal resections (-66%) and oncological lung resections (-43%).

Conclusion: This survey shows that due to the increased catchment area, more acute operations were performed and also demonstrated that we were confronted with more advanced stages of those diseases. Furthermore, cancer operations which rely on short-term peripheral diagnostics decreased considerably.

Background: The effects of cytotoxic chemotherapy on the expression of programmed death ligand 2 (PD-L2) are unknown and little is known about how the tumor microenvironment changes following neoadjuvant chemotherapy in locally advanced gastroesophageal adenocarcinomas (AEG). Recently, a number of studies reported that cytotoxic chemotherapy affects the expression levels of programmed cell death protein 1 (PD-1) and its ligand 1 (PD-L1). Regarding PD-L2, the second known ligand of PD‑1, no data on potential changes in expression patterns in patients with preoperatively treated AEG are available. The aim of this study was to investigate the impact of cytotoxic chemotherapy on PD-L2 expression in patients with resectable AEG.

Methods: Consecutive patients with locally advanced AEG treated with preoperative cytotoxic chemotherapy were included. PD-L2 expression by cancer cells (CCs) and tumor-infiltrating lymphocytes (TILs) was investigated in samples of paired diagnostic biopsies and resected tumor specimens by immunohistochemistry using two different anti-PD-L2 antibodies.

Results: Included were 40 patients with AEG and available paired tumor tissue samples. PD-L2 expression was observed in one diagnostic biopsy sample by CCs and in one diagnostic biopsy sample by TILs. There was no difference concerning the expression levels measured by the two antibodies.

Conclusion: In contrast to previously published studies reporting PD-L2 expression rates of up to 50% in AEGs, in our cohort, PD-L2 expression seems to play no significant role in AEG.
