Scoring systems & imaging alone do not accurately determine which patients develop severe pancreatitis. This case highlights clinical deterioration in a patient with an indolent presentation of alcoholic pancreatitis.
Case Description/
Methods: A 23-year-old woman with a history of alcohol use presented to the ED with worsening abdominal pain, nausea & retching over two weeks. She had prior visits for nausea & diarrhea; initially attributed to IBS. Patient was hemodynamically stable on admission & labs were notable for WBC 41.1 K/µL, Hb 15.1 g/dL Na 117 mEq/L, BUN 23 mg/dL, Ca 12.4 mg/dL, lactate 4.2 mmol/L, lipase 48 U/L. CECT of the abdomen & pelvis demonstrated severe pancreatitis with swelling, necrosis, & peripancreatic/free abdominal fluid. She received intravenous hydration and pain control. By day 4, hemoglobin dropped to 5.9 g/dL, with increased fluid collection & hemorrhagic features on CT. She was intubated for respiratory failure and required vasopressor support & blood transfusions in the ICU. Due to persistent abdominal pain, she underwent ERCP & cystogastrostomy and prophylactic IR embolization of the gastroduodenal artery & a dorsal pancreatic artery pseudoaneurysm. She later suffered a PEA arrest with ROSC achieved after six rounds of CPR. Due to a Hb of 5.3 & active hemorrhage on CTA massive transfusion protocol was initiated. She continued to decompensate with abdominal compartment syndrome and was not a candidate for ECMO. She was transitioned to comfort measures. Discussion: Early (< 24 hours) prognostication of SAP remains challenging, despite the existence of scoring criteria. Only 20% of patients develop SAP, & sequelae such as pseudoaneurysms occur in 1.3-10% of patients, with 3% developing active bleeding independent of size. Management is guided by the size, anatomy, and hemodynamic status of the patient. Transcatheter arterial embolization is first line therapy however has a rebleeding rate of 10-20%. Other approaches include endovascular techniques such as coil embolization, EUS-guided procedures, percutaneous embolization, and surgical options in severe cases. Combined approaches with EUS-guided drainage are often used in patients with pancreatic fluid collections. Despite embolization, & transient improvement, our patient suffered fatal rupture, highlighting its unpredictable course.
