“…The commonly used preoperative examinations of the liver include ultrasound, computed tomography (CT), and Magnetic resonance imaging (MRI), which provide important guidance for surgical preparation. In particular, contrast-enhanced CT and MRI can clearly show the vascular structure in the liver, including biliary strictures, biliary dilatation, and abnormal space-occupying lesions in the biliary tract[ 13 - 15 ]. However, in some cases, complex nonneoplastic liver lesions may interfere with the accurate interpretation of imaging results, which requires a review of the patient's detailed symptoms, signs, and the details of surgery history.…”

Time series analysis is a valuable tool in epidemiology that complements the classical epidemiological models in two different ways: Prediction and forecast. Prediction is related to explaining past and current data based on various internal and external influences that may or may not have a causative role. Forecasting is an exploration of the possible future values based on the predictive ability of the model and hypothesized future values of the external and/or internal influences. The time series analysis approach has the advantage of being easier to use (in the cases of more straightforward and linear models such as Auto-Regressive Integrated Moving Average). Still, it is limited in forecasting time, unlike the classical models such as Susceptible-Exposed-Infectious-Removed. Its applicability in forecasting comes from its better accuracy for short-term prediction. In its basic form, it does not assume much theoretical knowledge of the mechanisms of spreading and mutating pathogens or the reaction of people and regulatory structures (governments, companies, etc. ). Instead, it estimates from the data directly. Its predictive ability allows testing hypotheses for different factors that positively or negatively contribute to the pandemic spread; be it school closures, emerging variants, etc. It can be used in mortality or hospital risk estimation from new cases, seroprevalence studies, assessing properties of emerging variants, and estimating excess mortality and its relationship with a pandemic.

“…Many of the scoring systems used to predict and measureseverity are complex, cumber-some and inaccurate [3]. Some of them are: a) the Acute Physiology, Age and Chronic Health Evaluation (Apache II) [4,7,9,14]; b) Structured Interview of Reported Symptoms (SIRS) [4,9]; c) the Ranson score [4,7,9]; d) Bedside index for severity in AP (BISAP) (blood urea nitrogen >25mg/dl, impaired mental status, Systemic inflammatory response syndrome, age >60 years and pleural effusions) [2,3,15]; e) The Harmless Acute Pancreatitis Score (HAPS) (no rebound tenderness and/ or guarding, normal hematocrit and normal serum creatinine level) allows rapid identification of patients who present mild AP in 98% of cases; f) CT severity index (CTSI) based on local complications and percentage of pancreatic necrosis seen on a CT scan [2,4,5,17,18]. Various laboratory tests and biomarkers for predicting AP outcome have been described: a) elevated C-reactive protein (CRP) [1,4,13,14,19,20]; b) elevated hematocrit (Ht) [5,7,14,21,22]; and c) high serum creatinine, as a doubtful predictor of pancreatic necrosis [23,24].…”

“…El uso de distintos métodos de imagen permite evaluar la presencia de cálculos en la vía biliar, con sensibilidad y especificidad variable. El estudio de elección en primera instancia es la ecografía abdominal que tiene una sensibilidad en torno al 60%, dada principalmente por limitaciones relacionadas a la experiencia del operador y la dificultad de evaluar el colédoco intrapancreático (4) . Actualmente la colangiografía por resonancia magnética (CRM) es el examen no invasivo de elección, con sensibilidad global entre 81 a 100%, cercana al 100% en cálculos mayores a 5 mm (4) .…”

The term Choledocholithiasis refers to the presence of biliary stones in the extrahepatic bile ducts, which are found in 5 to 10% of patients undergoing cholecystectomy for gallstones. Nowadays, with the adoption of the laparoscopic cholecystectomy(LC) as a standard, multiple minimally invasive treatment options for bile duct stones are feasible, with no consensus to date on the procedure of choice. The two stage endoscopic techniques involve the use of Endoscopic Retrograde Cholangiopancreatography(ERCP) before or after performing a LC, which has the main advantage of separating the bile duct procedure from the LC. However, the need for two separate anesthesia times, the possibility of blank or failed ERCP, and the chance for calculi migration between procedures increase the length of hospital stay and associated costs. The single stage procedures include the Laparoscopic Bile Duct Exploration (LBDE), and more recently, the performance of a laparoscopy guided intraoperative ERCP(Rendez Vous). The LBDE, when performed by an experienced surgical team, is an effective and safe technique. Nonetheless, it is considered a technically demanding procedure, whose results cannot be extrapolated to the general surgical community. Recently, the Rendez Vous has become a treatment alternative that simplifies both the surgical and the endoscopic procedures, decreases morbidity, and requires a single anesthesia time. On the downside, Rendez Vous technique involves complex operating room (OR) logistics, requiring both a trained surgical and endoscopic team at the same time.
