EUS-Endodrill vs. EUS-FNA for Diagnosis of Submucosal Tumors in the Upper GI Tract

January 10, 2022 updated by: Martin Jeremiasen, Region Skane

Endodrill is a new instrument for biopsy sampling in the GI-channel. The purpose of this study is as follows:

- Compare EUS-guided Endodrill biopsies with endoscopic ultrasound guided fine needle aspiration (EUS-FNA) in terms of ability to establish the correct diagnosis of submucosal tumors in the upper GI tract.

Detailed Description

Endodrill is a newly constructed biopsy tool for flexible endoscopic use. It uses a drilling motion within a casing to harvest solid biopsies from tissue through the biopsy channel of a conventional flexible endoscope. It was originally designed for sampling of tissue from submucosal lesions. The investigators first study of the instrument is now finished. Endodrill is safe to use and generates more submucosal tissue compared to biopsies with a conventional biopsy forceps.

In this study the investigators want to compare the Endodrill instrument with FNA (both modalities EUS-guided) in terms of ability to obtain the correct diagnosis of submucosal tumors in the upper GI-tract. Patients diagnosed with suspected submucosal tumors in the upper GI-tract will be enrolled to this study. They will first go through examination with EUS. If the suspicion of a submucosal tumor is confirmed, the investigator will perform both EUS guided FNA and Endodrill biopsies in the same patient.The harvested tissue will be evaluated by senior pathologists to clarify which method that generates most correct diagnosis.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: EUS-FNA
All patients with a confirmed suspicion of a submucosal tumor in the upper GI tract will be included in this study. A senior endoscopist will perform multiple passes of EUS-FNA until she/he has collected enough material for the pathologist to establish a possible diagnosis.
Device: EUS-FNA
Please note the text in section "Arm description"
Active Comparator: EUS-Endodrill biopsy
All patients who are included in the study will also be examined by a senior endoscopist performing multiple EUS guided passes with the Endodrill biopsy. The harvested tissue from the tumor will be examined by a pathologist in order to establish a diagnosis.
Device: EUS-Endodrill biopsy
Please note the text in section "Arm description"
