Endoscopic Ultrasonography (EUS)

Endoscopic ultrasonography (EUS), or endosonography, combines endoscopy and ultrasonography in a single device. Endosonography is a high-tech research technique that shows the inside of the digestive system, as in standard endoscopy, and additionally allows to examine the outer layers of the digestive system and surrounding tissues (lymph glands and adjacent organs).

What is the difference between endoscopic ultrasonography (endosonography) and standard ultrasonography?

Since endoscopic ultrasonography (endosonography) is performed with endoscopy, the interior of the organs is entered and images are taken much more closely and in detail.
Since the main advantage of endoscopic ultrasonography is the sense of depth, it gives an idea about the deep spread of cancer and its involvement in the surrounding lymph nodes, vessels and organs in cases such as esophageal cancer, stomach cancer, rectum cancer, pancreatic cancer and rectal cancer, and allows biopsy from these regions.
Endoscopic ultrasonography (endosonography) shows the blood flow inside the vessels and is superior to standard ultrasonography.
Endoscopic ultrasonography (EUS) or endosonography is superior to standard ultrasonography in obtaining biopsy samples from lymph nodes.
For which diseases is endoscopic ultrasonography (endosonography) used?

Esophageal cancer, stomach cancer, rectum cancer, rectal cancer, bile duct cancer, pancreatic cancer: diagnosis, biopsy, early detection of cancer, investigation of recurrence in postoperative follow-up, investigation of tumor-wide regression if radiotherapy was given before the surgery, It is reported to be 80-99% effective in examining cancer involvement in neighboring organs around the rectum (prostate, bladder, vagina), lymph nodes and vessels and determining the grade of the tumor (T1, T2, T3, T4).
Soft tissue tumors originating from the digestive system: Connective tissue or soft tissue origin oil gland (lipoma), gastrointestinal stromal tumor (GIST), etc. arising from the walls of organs such as esophagus, stomach, rectum and anus. in the detection of tumors
Prostate cancer: diagnosis, biopsy
Biopsy of intra-abdominal lymph nodes: intestinal lymphoma, intestinal tuberculosis, etc. It is very effective in diagnosing diseases by pathological examination.
