Investigating the Shortcomings of the Flow Convergence Method for Quantification of Mitral Regurgitation in a Pulsatile In-Vitro Environment and with Computational Fluid Dynamics.

The flow convergence method includes calculation of the proximal isovelocity surface area (PISA) and is widely used to classify mitral regurgitation (MR) with echocardiography. It constitutes a primary decision factor for determination of treatment and should therefore be a robust quantification method. However, it is known for its tendency to underestimate MR and its dependence on user expertise.

"Surgery First" vs. "Endoscopy First" for Pediatric Choledocholithiasis Presenting at the End of the Week - A CARES Working Group Study.

Background: Choledocholithiasis in children is commonly managed with an "endoscopy-first" (EF) strategy (endoscopic retrograde cholangiopancreatography (ERCP) followed by laparoscopic cholecystectomy (LC)). Because ERCP availability is often limited at the end of the week (EoW), we hypothesized that a "surgery-first" (SF) approach (LC with intraoperative cholangiogram (IOC) ± transcystic laparoscopic common bile exploration (LCBDE)) would decrease length of stay (LOS) and time to definitive intervention (TTDI).

Methods: A multicenter, retrospective cohort study was conducted on pediatric patients from 2018 to 2023 with suspected choledocholithiasis.

Multi-Institutional Analysis of Choledocholithiasis in Pediatric vs Adult Patients.

Background: In adults, upfront intraoperative cholangiogram with laparoscopic common bile duct exploration (LCBDE) is well accepted for management of choledocholithiasis. Despite recent evidence supporting LCBDE utility in children, there has been hesitation to adopt this surgery first (SF) approach over ERCP first (EF) due to perceived technical challenges. We compared rates of successful stone clearance during LCBDE between adult and pediatric patients to evaluate if pediatric surgeons could anticipate similar rates of successful clearance.
