Anoscopy

Anoscopy is a quick bedside procedure in which a lighted tube called an anoscope examines the anal canal and distal rectum for hemorrhoids, fissures, and masses.

B-CLEAN trial

The B-CLEAN trial, a Canadian program of endoscopist-blinded randomized trials at 10 hospitals, found low-volume split-dose polyethylene glycol bowel preparation noninferior to high-volume for colonoscopy cleansing.

Balloon endoscopy

Balloon endoscopy, also called balloon-assisted or device-assisted enteroscopy, uses inflatable balloons on an enteroscope and overtube to advance deep into the small intestine, supporting biopsies and hemostasis.

Balloon enteroscopy

Balloon enteroscopy is an endoscopic technique that uses a balloon-tipped overtube to advance a long enteroscope deep into the small intestine, diagnosing and treating small-bowel disease without surgery.

Bowel cleansing

Bowel cleansing, also called bowel preparation, clears the intestines of fecal matter with laxative solutions, dietary restriction, and fluids, most often before colonoscopy, since inadequate cleansing causes most incomplete examinations.

Bowel preparation

Bowel preparation is the clinical process of clearing fecal material from the colon with laxatives, diet, and fluids before a colonoscopy, so the lining can be inspected reliably.

Capsule Endoscopes

Capsule endoscopes are swallowable wireless pill cameras imaging the GI mucosa, invented by Gavriel Iddan and Paul Swain, FDA-approved in 2001 as Given Imaging's M2A/PillCam, now first-line for small-bowel bleeding and Crohn's evaluation.

Capsule endoscopy

Capsule endoscopy is a diagnostic procedure in which the patient swallows a miniature wireless camera that images the small bowel, first used in humans in 1999.

Colon capsule endoscopy

Colon capsule endoscopy is a diagnostic test in which the patient swallows a camera capsule that photographs the colon to detect polyps, colorectal cancer, and inflammation without sedation.

Colonoscopes

Colonoscopes are flexible endoscopes inserted through the anus to visualize the entire colon for diagnosis and polyp removal. Developed from Niwa and Yamagata's fiberoptic design, first used modernly by Wolff and Shinya in June 1969.

Colonoscopy screening

Colonoscopy screening examines the entire colon in asymptomatic adults to detect colorectal cancer and remove precancerous polyps during the same procedure, recommended every 10 years.

Diagnostic colonoscopy

Diagnostic colonoscopy is an endoscopic procedure in which a flexible, camera-equipped instrument examines the entire colon; it is the reference test for colorectal cancer screening, reducing CRC incidence by 31% to 91%.

Double-balloon endoscopy

Double-balloon endoscopy is an endoscopic technique in which two inflatable balloons grip the intestinal wall, allowing deep small-bowel examination and treatment without surgery, first reported in 2001.

Double-Balloon Enteroscopy

Double-balloon enteroscopy (DBE), invented by Hironori Yamamoto and first reported in 2001, is a balloon-assisted deep enteroscopy technique using an endoscope and overtube with two balloons; distinct from single-balloon and spiral enteroscopy.

Duodenoscopy

Duodenoscopy is the endoscopic examination of the duodenum using a flexible scope passed through the mouth; the side-viewing duodenoscope visualizes the major papilla and serves as the platform for ERCP.

Endoscopic retrograde appendicitis therapy

Endoscopic retrograde appendicitis therapy (ERAT) is a colonoscopic procedure treating uncomplicated appendicitis by removing fecaliths and draining pus to preserve the appendix, first reported in 2012.

Enteroscopy

Enteroscopy is an endoscopic examination of the small intestine for obscure bleeding, tumors, and Crohn's disease; device-assisted techniques use balloons or a spiral overtube to reach deep bowel.

Esophagoscopes

Esophagoscopes are thin, lighted tube instruments, rigid or flexible, for examining the esophagus. Includes Chevalier Jackson's 1890 rigid design, LoPresti's 1964 fiberscope, and 4.5–5.1 mm transnasal office scopes.

Esophagoscopy

Esophagoscopy is an endoscopic examination in which a flexible or rigid scope is passed through the mouth to inspect the esophagus lining, detecting strictures, tumors, varices, and foreign bodies.

Functional luminal imaging

Functional luminal imaging (FLIP) is an endoscopic technique that measures the size and compliance of a distended gastrointestinal lumen by impedance planimetry, used mainly to assess the esophagogastric junction in motility and reflux disease.

Gastrointestinal Endoscopes

Gastrointestinal endoscopes are instruments for visual examination of the GI tract, spanning gastroscopes, colonoscopes, duodenoscopes, and capsule endoscopes; evolved from Kussmaul's 1868 rigid gastroscope through fiberoptic (1957) and video (1983) designs, with reprocessing and AI now central.

Gastrointestinal Endoscopy (procedure)

Gastrointestinal endoscopy: endoscope-based visualization, biopsy, and treatment of the digestive tract. From Kussmaul's 1868 rigid gastroscope to fiberoptic, CCD video, and capsule endoscopes; over 7.4 million EGDs yearly in the US.

Gastrointestinal stenting

Gastrointestinal stenting is an endoscopic or radiologic procedure in which a self-expanding metal tube holds open a narrowed digestive tract, used mainly to relieve malignant obstruction and, in selected colon cancer, as a bridge to surgery.

Gastroscopes

Gastroscopes, also called upper endoscopes or EGD scopes, are flexible camera tubes for examining the esophagus, stomach, and duodenum; diameters 4.9–12.8 mm, with single-use and reusable variants compared in recent evidence.

Gastroscopy

Gastroscopy, also called esophagogastroduodenoscopy or EGD, is an endoscopic procedure in which a flexible camera passed through the mouth examines the esophagus, stomach, and upper duodenum.

High-resolution anoscopy

High-resolution anoscopy (HRA) is a colposcopic examination of the anal canal that detects precancerous lesions, the preferred method for anal cancer screening in high-risk groups.

Magnet-controlled capsule endoscopy

Magnet-controlled capsule endoscopy, also called magnetically guided capsule endoscopy, is a diagnostic technique in which a swallowed video capsule is steered through the stomach by an external magnetic field, without sedation.

Pouchoscopy

Pouchoscopy is the endoscopic examination of the ileal pouch after ileal pouch–anal anastomosis (IPAA) surgery, the primary diagnostic test for pouch disorders, above all pouchitis, with biopsy when needed.

Proctoscopes

Proctoscopes (also rectoscopes) are rigid endoscopes for visual examination of the rectum and anus, about 25 cm long with a light and lens; used in proctoscopy, biopsy, hemorrhoid treatment, and rectal cancer localization.

Proctoscopy

Proctoscopy is an endoscopic examination in which a lighted rigid tube, the proctoscope, is inserted through the anus to inspect the rectum, taking 5 to 15 minutes.
