A choledochal cyst is a cystic dilatation that affects both the intrahepatic and extrahepatic biliary tree. The most commonly used classification to describe this pathology is that of Todani et al. (1997), which includes five categories. It is usually asymptomatic, but may present with symptoms such as abdominal pain, jaundice and fever. The gold standard for diagnosis is magnetic resonance cholangiopancreatography (MRCP). Patients with choledochal cysts have an increased risk of carcinogenesis. The neoplasms most commonly associated with choledochal cysts are cholangiocarcinoma and gallbladder cancer. Type I and V cysts are the most likely to undergo malignant transformation, while it is rarer in types II and III. Treatment consists of the surgical excision of the cyst with Roux-en-Y biliodigestive reconstruction. The laparoscopic approach is currently the most commonly used. Biliary dr...

Objectives: The worldwide heart failure (HF) prevalence is 8.52 per 1000 inhabitants, with a global economic burden of 346.17 billion dollars. With the COVID-19 pandemic, the focus of medical care has changed to treating the morbidity and mortality of patients with COVID-19 and reducing medical procedures or visits to patients with HF, with the impact being greater in low- and middle-income countries. Methods: We performed an interrupted time series analysis of HF to determine the changes in the trend of hospitalizations and in-hospital mortality of HF patients before and after the mandatory lockdown in Peru. Results: A total of 18,514 adults were included in the analysis. Monthly hospital admissions immediately decreased by 599 (95% confidence interval [CI]: 113 to 1085) and the difference in slope before and after the lockdown was 6.4 hospital admissions (95% CI: −4 to 18). In-hospit...
