Brief summary: The implementation of Echo-endoscopy (or EUS for: Endoscopic UltraSound) is limited by the difficulty of obtaining quality EUS procedures, since the accuracy of the method relies on the endoscopist's abilities. Indeed, both cognitive and technical skills are required for endoscopic manipulation and image interpretation, as well as a thorough knowledge of intra-abdominal anatomy. The "EUS-GPS" system aims to assist the operator in understanding the orientation and location of the probe tip within the patient. For that, a Global Positioning System (GPS) for EUS procedures is intraoperatively provided, using a 3D-based model based on recorded preoperative data.

In this clinical investigation, the EUS GPS system is intended to help EUS operators to correctly navigate towards the pancreatic gland, perform a comprehensive assessment of the area of interest, and aid in the detection and identification of lesions.

Detailed description: Since its emergence in the 1980s, endoscopic ultrasound (EUS) is considered as one of the most accurate tools for the evaluation of the pancreatic gland and other gastrointestinal (GI) disorders. Despite its utility, the practice of EUS is still far from being part of every endoscopy suite due to its high set-up cost and the relative scarcity of credentialed experts. EUS implementation worldwide has been limited by the difficulty of achieving quality EUS procedures, since the accuracy of the method relies on the endoscopist's abilities. Both cognitive and technical competencies are required for endoscopic manipulation and image interpretation, as well as extensive knowledge of intraabdominal anatomy.

The aim of the APEUS (Augmented Pancreatic Endoscopic UltraSound) project is to overcome these two main difficulties by providing a Global Positioning System (GPS)-like intraoperative navigation for EUS procedures, using a 3D-based model on registered preoperative data. The hypothesis is that, thanks to this tool, the procedures time would be shortened, and the pancreas and its lesions would be completely imaged. This would reduce the demand for experts guiding trainees and shorten the EUS learning curve.

This first-in-human clinical study will enable the assessment of safety and qualitative performance of the EUS-GPS solution. The primary objective is to evaluate the EUS navigation system's procedure duration compared to standard procedure times (patient group with the EUS-GPS system vs control group without).

Eligibility criteria: Inclusion Criteria:

* Patient affiliated to the French social security system

Exclusion Criteria:

* Patient unable to give informed consent
* Patient with altered anatomy of the upper digestive tract due to previous surgery
* Patient with known abnormal anatomy of the upper digestive tract
* Patient wearing a metal implantable device (pacemaker, etc.)

* Patient with an ASA (American Society of Anesthesiologists) score \>2
* Patient with multiple pancreatic lesions.
* Patient unable to tolerate general anaesthesia
* Patient with a body mass index (BMI) \< 23 and \> 40
