PRUE trial
PRUE (NCT01653171), a Chilean randomized double-blind trial by Monrroy et al, tested simethicone with or without N-acetylcysteine before upper GI endoscopy; simethicone plus NAC improved gastric visibility (65-67% vs 41-44%), simethicone alone did not.
Sigmoidoscopes
Sigmoidoscopes, rigid or flexible endoscopes with a light and camera, examine the rectum and sigmoid colon. Flexible versions, introduced by Overholt in 1962, screen for distal colorectal cancer with low complication rates.
Single-balloon enteroscopy
Single-balloon enteroscopy is an endoscopic technique using an overtube with a single balloon to reach the small intestine for biopsy and therapy, mainly for obscure gastrointestinal bleeding.
Small intestinal biopsy
A small intestinal biopsy is a diagnostic procedure that takes mucosal tissue samples from the duodenum during upper endoscopy and examines them under the microscope, principally to diagnose celiac disease.
Spiral enteroscopy
Spiral enteroscopy is a device-assisted deep enteroscopy technique in which a rotating spiral-tipped overtube pleats the small intestine over the enteroscope, allowing diagnosis and treatment of small-bowel disease.
Surveillance colonoscopy
Surveillance colonoscopy is the repeated colonoscopic examination at set intervals of people at increased risk of colorectal cancer, including those after polyp removal, with IBD, or with hereditary syndromes.
Transnasal endoscopy
Transnasal endoscopy (TNE) is an office-based upper GI endoscopy in which an ultra-slim gastroscope is passed through the nose without sedation, used for dysphagia, reflux, varices screening, and Barrett's surveillance.
