ERCP-guided percutaneous fine-needle pancreatic biopsy

Area of Science:

• Gastroenterology
• Oncology
• Radiology

Background:

• Unresectable pancreatic carcinoma diagnosis historically required invasive exploratory laparotomy for tissue confirmation.
• Minimally invasive diagnostic techniques are crucial for improving patient outcomes and reducing healthcare burdens.

Purpose of the Study:

• To evaluate the safety and accuracy of percutaneous fine-needle aspiration biopsy for diagnosing unresectable pancreatic carcinoma.
• To determine the efficacy of endoscopic retrograde cholangiopancreatography (ERCP) in guiding percutaneous biopsies for pancreatic cancer.

Main Methods:

• Retrospective analysis of patients with radiologic diagnosis of unresectable pancreatic carcinoma.
• Percutaneous fine-needle aspiration biopsy performed under ERCP guidance.
• Cytologic examination of biopsy specimens for adenocarcinoma.

Main Results:

• Percutaneous fine-needle aspiration biopsy provided safe and accurate histologic confirmation in the majority of cases.
• ERCP precisely localized the biopsy site in 13 out of 14 patients (93%) with pancreatic carcinoma.
• The procedure successfully diagnosed adenocarcinoma, obviating the need for exploratory laparotomy.

Conclusions:

• Percutaneous fine-needle aspiration biopsy is a reliable alternative to exploratory laparotomy for diagnosing unresectable pancreatic cancer.
• ERCP-guided biopsy is an effective method for obtaining tissue diagnosis of pancreatic adenocarcinoma.
• This minimally invasive approach enhances diagnostic safety and accuracy in pancreatic cancer management.
