Bedside Monitoring of Microenvironmental Changes in Infected Pancreatic Collections

This pilot clinical study aims to assess the feasibility and clinical relevance of bedside monitoring of microenvironmental conditions within infected walled-off pancreatic necrosis (WOPN).

WOPN is a serious complication of acute pancreatitis, often associated with infection, organ failure, and the need for drainage or surgical intervention. Although infection is a key factor in prognosis, little is known about the local chemical environment inside the infected collections.

In this study, a sterile, miniaturized probe will be temporarily introduced into the necrotic cavity during standard percutaneous drainage. The goal is to record local microenvironmental parameters (such as acidity or related values) and monitor their changes over time.

By comparing these values with clinical data (e.g., inflammatory markers, microbiology, need for surgery), the study aims to determine whether such measurements can provide additional information about infection severity and treatment response.

The study does not involve any experimental treatment. All patients will receive standard medical care, including antibiotics, imaging, and drainage according to international guidelines.

Participation is voluntary. Only patients who provide informed consent will be enrolled.
