Related to endoscopist: endoscopically


any instrument used to look inside the body. Usually consisting of a fiber-optic tube attached to a viewing device, endoscopes are used to explore and biopsy such areas as the colon and the bronchi of the lungs. Endoscopes employing miniature television cameras and tiny surgical implements now allow exploration and endoscopic surgery through small incisions; such surgery is much less traumatic to the patient than traditional open surgery. Laparoscopic surgery, in which the endoscope is inserted through a small incision in the abdomen or chest, is used to correct abnormalities of the ovaries and as an alternative to traditional gall bladder and chest surgery. Arthroscopic surgery is endoscopic surgery performed on joints such as the knee or shoulder.

The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.



a medical instrument for the examination of hollow organs (for example, the esophagus, stomach, and bronchi) and the abdominal and other body cavities. Endoscopes have optical and illumination systems. There are two basic types: rigid endoscopes (for example, proctoscopes), which use optical systems of lenses, and flexible fiberscopes (for example, esophago-gastroscopes), which use fiber optics. Fiberscopes make possible the examination of organs that cannot be seen with rigid endoscopes (for example, the duodenum). The optical systems of flexible endoscopes consist of numerous glass fibers (light guides), which measure 0.01–0.02 mm in diameter.

The use of endoscopes not only has made possible the examination of various organs but also has aided greatly in the visual guiding of biopsy procedures and in surgery (removal of foreign bodies and polyps, coagulation of bleeding vessels). Modern endoscopes permit complication-free examination.

Stent migration is an uncommon situation encountered by endoscopists. Every effort should be made to retrieve migrated stent safely endoscopically by employing various techniques, thus avoiding potential complications and obviating the need of a radiological procedure or surgery.
There were no differences in the endoscopist's experience between the PQL and SD scope groups.
However, obese cases that are frequently encountered in everyday practice may pose a problem during colonoscopies for the endoscopists due to inadequate intestinal cleansing as well as phenotypic characteristics.
This study demonstrated that the propofol/fentanyl combination did produce better quality of anesthesia for the procedure than with propofol alone as judged by the blinded endoscopists. The blinded endoscopists' numerical scoring of the quality of anesthesia was subjective, still, it did provide a consistent means of comparison between the two groups.

Whereas existing classification systems only include patients with "flat" BE, high-definition endoscopy now allows the endoscopist to appreciate that many of these areas have subtle nodularity or ulceration [4, 37, 38].
In our cases, the endoscopist did not succeed in removing the object because of the size (too big to be grasped with the diathermic snare) and the material (too smooth and slipping for the clamp).
All colonoscopies were performed by five expert colonoscopists (gastroenterologists >1000 colonoscopies) certified by the Korean Society of Gastrointestinal Endoscopy and other endoscopists (<300 colonoscopies) by using a CF-Q260AI/AL or CF-H260AI/AL system (Olympus, Tokyo, Japan).
Provision was made in the NMS for findings in categories, namely demographics, the specific organs of the upper GIT (namely oesophagus, stomach and duodenum) and miscellaneous including diagnosis, name and signature of endoscopist as well as date and legibility.
(2,5,8-13) There is a paucity of data evaluating a single endoscopist's performance at different institutions.
