Spontaneous biliary perforation (SBP) in pediatrics is rare and historically has been treated with laparotomy for attempted repair and cholecystectomy. In recent years, management has evolved into a conservative approach, opting for cholecystostomy and peritoneal drainage over cholecystectomy. In this case, we report the first successful conservative management of SBP using an exclusively laparoscopic approach without cholecystectomy in a pediatric patient.

We tested several molecular and cellular mechanisms of cardiomyocyte contraction-relaxation function that could account for the reduced systolic and enhanced diastolic function observed with exposure to extracellular Zn(2+). Contraction-relaxation function was monitored in isolated rat and mouse cardiomyocytes maintained at 37°C, stimulated at 2 or 6 Hz, and exposed to 32 μM Zn(2+) or vehicle. Intracellular Zn(2+) detected using FluoZin-3 rose to a concentration of ∼13 nM in 3-5 min.
