Diagnosis of Lung Abscess and Pancreatic Collection Using Transesophageal and Transgastric Point-of-Care Ultrasound in a Critically Ill Patient.

Effectively managing critically ill septic patients requires careful utilization of imaging techniques. While point-of-care ultrasound (POCUS) is invaluable in the ICU, it faces challenges with conventional transcutaneous ultrasound, especially in obese patients. A 22-year-old obese female presented with abdominal pain and renal dysfunction. Abdominal CT confirmed acute biliary pancreatitis, progressing to respiratory failure. Transesophageal and transgastric ultrasound revealed a pulmonary abscess and peripancreatic collection. Expectant management of the lung abscess and percutaneous drainage of the pancreatic collection led to successful recovery. This case highlights POCUS's pivotal role in timely diagnosis, particularly in severe pancreatitis, showcasing its versatility in critical care.
