The medical term for the formal procedure of accessing the gastrointestinal tract for examination is endoscopy. Endoscopy is a minimally invasive procedure that enables a healthcare provider to visualize the interior of the gastrointestinal tract using a flexible tube equipped with a camera and light source, known as an endoscope. This technique allows for detailed examination and assessment of the esophagus, stomach, and intestines, and it can be used for both diagnostic and therapeutic purposes, such as biopsy or removal of polyps.

Other options like gastrectomy refer to the surgical removal of part or all of the stomach, which is not simply an examination but an invasive surgical procedure. Laparoscopy is a surgical technique that involves making small incisions in the abdomen to access the abdominal cavity, which may or may not involve examining the gastrointestinal tract directly. Colonoscopy, while also a method of examining the intestines, is specifically focused on the colon and rectum and is considered a subset of endoscopic procedures. Thus, endoscopy encompasses a broader range of gastrointestinal examinations beyond just one specific area.
