The association between sonographic common bile duct dilatation and outcomes in emergency department patients with cholangitis.

BACKGROUND: The presentation of the patient with acute cholangitis (AC) ranges from mild illness to life-threatening shock. Therefore, prompt diagnosis and treatment are critical. Abdominal ultrasound (US) is the imaging of choice to locate bile duct dilatation. Other modalities include abdominal computed tomography (CT) or endoscopic retrograde cholangiopancreatography (ERCP). OBJECTIVES: To determine whether sonographic common bile duct dilatation in emergency department (ED) patients with AC predicts outcomes including sepsis, hospital length of stay (LOS), admission to the intensive care unit (ICU), time to ERCP, and mortality. METHODS: Electronic medical records of all patients hospitalized in a tertiary care medical center between July 2012-February 2021 with a discharge diagnosis of cholangitis were assessed. Patients were dichotomously classified as CBD dilated or CBD non-dilated based on ultrasound. Dilation was defined as CBD larger than 6 mm in patients younger than 60 or larger than 6 mm + 1 mm per decade in patients over 60. RESULTS: The study included 271 patients- 172 with CBD dilation versus 99 without. Mean LOS was 9.92 days for those with a dilated CBD versus 13.4 days without. The mean time to ERCP was 4.26 days for those with a dilated CBD versus 6.56 days without. Sepsis, mortality, and ICU admission were scarce and there was no statistically significant difference between the cohorts. CONCLUSION: Patients with a dilated CBD per the abdominal US performed during the patient's ED stay, underwent ERCP earlier, and were hospitalized fewer days than patients without CBD dilation.

Decompressive Laparotomy for Veno-Venous Extracorporeal Membrane Oxygenation Failure due to Intra-Abdominal Hypertension in Critically Ill COVID-19 Patient.

The use of extracorporeal membrane oxygenation (ECMO) has increased over the course of the SARS-CoV-2 pandemic. Intra-abdominal hypertension resulting in abdominal compartment syndrome (ACS) during ECMO support is a rare but life-threatening complication, with previous case series describing mortality rates of 44%-100%. Bleeding complications, linked to both patient-related and device-related factors, also characterize prolonged ECMO support and have been reported in up to 60% of ECMO patients. We hereby describe a critically ill COVID-19 patient who underwent emergent bed-side decompressive laparotomy for acute ECMO failure related to the development of ACS. The discussion is focused on surgical considerations including the delicate balance between anticoagulation and thrombosis, as anticoagulation-free ECMO support may be required due to hemorrhagic complications.
