Abstract
BACKGROUND
Infected acute necrotic collection (ANC) is a fatal complication of acute pancreatitis with substantial morbidity and mortality. Drainage plays an exceedingly important role as the first step in invasive intervention for infected necrosis; however, there is great controversy about the optimal drainage time, and better treatment should be explored.
CASE SUMMARY
We report the case of a 43-year-old man who was admitted to the hospital with severe intake reduction due to early satiety 2 wk after treatment for acute pancreatitis; conservative treatment was ineffective, and a pancreatic pseudocyst was suspected on contrast-enhanced computed tomography (CT). Endoscopic ultrasonography (EUS) suggested hyperechoic necrotic tissue within the cyst cavity. The wall was not completely mature, and the culture of the puncture fluid was positive for A-haemolytic Streptococcus. Thus, the final diagnosis of ANC infection was made. The necrotic collection was not walled off and contained many solid components; therefore, the patient underwent EUS-guided aspiration and lavage. Two weeks after the collection was completely encapsulated, pancreatic duct stent drainage via endoscopic retrograde cholangiopancreatography (ERCP) was performed, and the patient was subsequently successfully discharged. On repeat CT, the pancreatic cysts had almost disappeared during the 6-month follow-up period after surgery.
CONCLUSION
Early EUS-guided aspiration and lavage combined with late ERCP catheter drainage may be effective methods for intervention in infected ANCs.
Core Tip: Infected acute necrotic collection (ANC) is a potentially fatal disease. Endoscopic ultrasound (EUS)-guided fine-needle aspiration is recommended when the diagnosis is unclear. Endoscopic drainage is the optimal treatment for infected necrosis and is generally performed 4 wk after onset. Herein, we present a case in which an infected ANC was misdiagnosed as a pancreatic pseudocyst and was successfully treated by early EUS-guided aspiration and lavage combined with late endoscopic retrograde cholangiopancreatography catheter drainage. EUS-guided aspiration and lavage may be used as a bridge while waiting for the necrotic collection to be fully encapsulated before draining.
