Efficacy of Endoscopic Ultrasound in Preoperative Assessment of Pancreatic Head Tumors from A Surgical Perspective: A Prospective Study

Abstract

Background: Cancer of the pancreatic ducts, often known as pancreatic ductal carcinoma, is the most common type of pancreatic cancer.

Objectives: This study aimed to assess the accuracy, specificity, and sensitivity of endoscopic ultrasound in diagnosis of pancreatic head  tumors and detection of lymph node metastasis, tumor size, vascular invasion and local infiltration of surrounding organs based on surgical assessment.

Patients and methods: This prospective study of forty consecutive patient who presented to the Gastrointestinal Surgical Center during  the period from 2020 to 2023.

Results: There was statistical significance difference between the Endoscopic Ultrasound (EUS) results and CT vascular results only in the studied patients. There was high statistically significant difference between the EUS results and operational LNs results in the studied  patients. There was high statistical significance difference between the EUS results and operational vascular results in the studied  patients.

Conclusion: The use of EUS to confirm a pancreatic cancer diagnosis is highly encouraging. Lymph node metastases as well as  vascular invasion can be effectively detected using this method. Removing the tumor entirely also improves the chances of a successful  recovery after operation.
