This is a relatively safe procedure with very few complications and helps to clearly identify lesions of the upper gastrointestinal tract.
Currently, people have attached to the end of the endoscope an ultrasound probe that allows to conduct ultrasound examination from within the gastrointestinal tract and this technique is called endoscopic ultrasound. This is a technique combining endoscopy and ultrasound, in which the ultrasound probe is approached closest (no longer the limitations of conventional ultrasound such as air entanglement, image noise, ...) to the lesions. need endoscopic exploration: damage to the wall of the esophagus, stomach, intestines, liver, pancreas and biliary tract.

During a routine gastroscopy, before the procedure, the patient will be sprayed with an anesthetic spray into the throat (if required). The patient is placed on the left side. During an average colonoscopy of about 10 minutes, air will be pumped into the stomach through a flexible endoscope that passes through the pharynx, and the air will be sucked out at the end of the procedure. Patients can choose to use endoscopic ultrasound with anesthesia. This method helps the patient to sleep during the endoscopy, without feeling uncomfortable or scared like a conventional endoscopy.
