Cold snare polypectomy of colorectal polyps sometimes leaves a cord of white tissue consisting of submucosa and, sometimes, muscularis mucosa. These defects are called “cold

In a prospective study from Singapore, the computer-aided diagnosis (CADx) program CAD EYE (Fujifilm, Tokyo, Japan) was assessed in 661 consecutive polyps of all sizes

Polyp size measurements by endoscopists during colonoscopy are notoriously inaccurate, with both over-measurements and under-measurements. Computerized assessments of polyp size are promising for more accurate

Follow-up intervals after polypectomy Colonoscopy is the most reliable procedure for detecting colorectal carcinomas and polyps. The aim of colonoscopy must be to achieve a

Since 2017, ESGE guidelines require that a standard snare should no longer be used for the removal of small polyps, and especially diminutive polyps. The

Recently sessile serrated lesions (SSLs) have been recognized as another important precursor lesion to CRC. SSLs are thought be responsible for 15–30% of colorectal cancer.

Cold snare resection has been established in diminutive polyps (up to 5 mm) as being at least as safe and partially more effective than biopsy

In the following, examples for superficial/early Barrett lesions of the esophagus are shown. Here, flat and sessilelesions are predominant, pedunculated tumors are rare. Sessile tumor

The Paris classification for superficial / early tumors should be part of a standard terminology for endoscopic assessment. This classification applies to the entire gastrointestinal

Examples of superficial/early squamous cell lesions in the esophagus are presented below. In the esophagus, flat lesions are predominant in the early tumors, and polypoid
