Post-Cholecystectomy Pancreatitis When Zero Means Lethal: Fulminant Post-Cholecystectomy Pancreatitis Following a Benign Initial Ranson Score-A Case Report.

Post-cholecystectomy pancreatitis (PCP) represents a rare yet potentially lethal iatrogenic complication whose clinical management is frequently undermined by an insidious progression and the fallibility of traditional prognostic models. We present a compelling case of fulminant PCP in a 46-year-old female whose fatal trajectory powerfully illustrates these limitations. Presenting on the fourth postoperative day following an open cholecystectomy, her diagnosis was confirmed by elevated pancreatic enzymes and common bile duct dilation; however, her initial Ranson score was 0, prognosticating minimal risk. After a deceptive 48-h period of apparent stabilization, her course was marked by a precipitous decline into multi-organ failure, including acute renal failure, severe hepatocellular injury, and a delayed onset of Systemic Inflammatory Response Syndrome (SIRS) on day seven, culminating in fatal cardiopulmonary arrest. This case demonstrates that a benign initial Ranson score can be a dangerously misleading prognosticator in PCP, establishing the critical need for heightened clinical vigilance to supersede reliance on initial scoring and advocating for a lower threshold for intensive care monitoring irrespective of a seemingly low-risk presentation.
