Abstract
BACKGROUND

Pancreatic ductal leaks complicated by endoscopic ultrasonography-guided tissue sampling (EUS-TS) can manifest as acute pancreatitis.

CASE SUMMARY

A 63-year-old man presented with persistent abdominal pain and weight loss. Diagnosis: Laboratory findings revealed elevated carbohydrate antigen 19-9 (5920 U/mL) and carcinoembryonic antigen (23.7 ng/mL) levels. Magnetic resonance imaging of the pancreas revealed an approximately 3 cm ill-defined space-occupying lesion in the inferior aspect of the head, with severe encasement of the superior mesenteric artery. Pancreatic ductal adenocarcinoma was confirmed after pathological examination of specimens obtained by EUS-TS using the fanning method. Interventions and outcomes: The following day, the patient experienced severe abdominal pain with high amylase (265 U/L) and lipase (1173 U/L) levels. Computed tomography of the abdomen revealed edematous wall thickening of the second portion of the duodenum with adjacent fluid collections and a suspicious leak from either the distal common bile duct or the main pancreatic duct in the head. Endoscopic retrograde cholangiopancreatography revealed dye leakage in the head of the main pancreatic duct. Therefore, a 5F 7 cm linear plastic stent was deployed into the pancreatic duct to divert the pancreatic juice. The patient’s abdominal pain improved immediately after pancreatic stent insertion, and amylase and lipase levels normalized within a week. Neoadjuvant chemotherapy was then initiated.

CONCLUSION

Using the fanning method in EUS-TS can inadvertently cause damage to the pancreatic duct and may lead to clinically significant pancreatitis. Placing a pancreatic stent may immediately resolve acute pancreatitis and shorten the waiting time for curative therapy. When using the fanning method during EUS-TS, ductal structures should be excluded to prevent pancreatic ductal leakage.

Core Tip: Endoscopic ultrasound guided tissue sampling is a crucial procedure for histological diagnosis of pancreatic lesions, but it may occasionally be accompanied by unforeseen complications. The Fanning method is a technique that can enhance diagnostic accuracy, but it also carries the risk of unintended ductal injury. Here, we report a case where the use of the Fanning method during endoscopic ultrasound guided tissue sampling resulted in leakage of the pancreatic duct. We successfully managed this complication by performing pancreatic duct stent via endoscopic retrograde cholangiopancreatography.
