Using Spyglass for Diagnosis, ERCP, and Radical Surgery: A Case of Precision Treatment for Cholangio
Using Spyglass for Diagnosis, ERCP, and Radical Surgery: A Case of Precision Treatment for Cholangiocarcinoma
Cholangiocarcinoma is a relatively rare malignant tumor, accounting for less than 1% of all systemic tumors and about 3% of digestive system tumors. In recent years, its incidence has shown an increasing trend. It mostly affects people aged 50–70, with a male-to-female ratio of 1.4:1. It is classified into hilar cholangiocarcinoma and distal cholangiocarcinoma. Common causes include abnormal pancreatobiliary junction, biliary cysts/residual biliary cysts, recurrent pyogenic cholangitis, hepatolithiasis, postoperative biliary inflammation, primary sclerosing cholangitis, and viral hepatitis.
Early-stage cholangiocarcinoma often presents no obvious clinical symptoms. As the lesion progresses and enlarges, obstructive jaundice may occur due to biliary obstruction. With further progression, symptoms such as right upper quadrant pain, nausea, abdominal mass, vomiting, pale stools, dark urine, and itchy skin may appear. Cholangiocarcinoma is highly malignant, and early detection and diagnosis are challenging. Often, the disease is already advanced at diagnosis, leading to a poor prognosis.
Diagnosis requires a combination of clinical presentation, abdominal imaging, and pathological examination. Our hospital now employs endoscopic ultrasound and Spyglass (choledochoscopy) to enable earlier detection and more precise pathological examination, thereby improving diagnostic accuracy.
Case Study
A patient, Mr. Ma, sought medical attention in October 2022 due to "sudden upper abdominal distension and pain for 5 days." Abdominal MRI upon admission indicated: pancreatic thickening with heterogeneous enhancement, reduced enhancement signal in the pancreatic head, enlarged lymph nodes in the portal–caval venous space, suggesting possible tumor. Peripancreatic effusion and pancreatic duct dilation were observed, consistent with acute pancreatitis. Mild intra- and extrahepatic biliary dilation and stenosis of the pancreatic segment of the common bile duct were noted, along with multiple gallstones.


After admission, symptomatic treatments such as anti-infection therapy, enzyme inhibition, and fluid replacement were administered. Endoscopic retrograde cholangiopancreatography (ERCP) with nasobiliary drainage was performed. Endoscopic ultrasound revealed an irregular hypoechoic lesion in the pancreatic head, dilation of the main pancreatic duct, invasion of the pancreatic segment of the common bile duct, and a solid irregular lesion within the duct wall. An enlarged hypoechoic lymph node was observed near the portal vein. Pathological examination of the endoscopic ultrasound-guided pancreatic biopsy showed: (Pancreatic head puncture tissue) blood clot-like material with a small amount of pancreatic tissue, consistent with acute pancreatitis and necrotic changes.


Although the initial biopsy did not support a tumor diagnosis, abdominal MRI and endoscopic ultrasound suggested possible invasion of the common bile duct and enlarged lymph nodes near the portal vein. To avoid misdiagnosis, Spyglass examination was performed. Spyglass choledochoscopy revealed destruction, hyperplasia, and diffuse stenosis in the middle and lower segments of the bile duct, with fragile tissue prone to bleeding. Pathological examination confirmed adenocarcinoma of the distal common bile duct.

The patient subsequently underwent preoperative chemotherapy followed by radical surgery for cholangiocarcinoma at our hospital.
This case highlights the significant diagnostic value of endoscopic ultrasound and Spyglass in identifying cholangiocarcinoma. The patient, initially presenting with abdominal pain and MRI findings suggestive of acute pancreatitis and enlarged portal vein lymph nodes, was ultimately diagnosed with cholangiocarcinoma through advanced endoscopic techniques.
