Minimally invasive techniques
During the exam, an endoscope is passed through a natural opening in the body (such as the mouth or anus) or your doctor may make a small incision, such as in the pelvic or abdominal area for a laparoscopic exam.
Endoscopy can also be used to perform a biopsy or remove tissue, and the endoscope can be fitted with various devices such as lasers, ultrasound devices or tiny surgical instruments. A mild sedative is used during most endoscopic procedures.
