String capsule endoscopy for screening and surveillance of esophageal varices in patients with cirrhosis.

Background: EGD is the gold standard for the screening and surveillance of esophageal varices. A less invasive, safer and sedationless alternative procedure is needed.

Objective: To assess the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) as well as the beyond the chance agreement (kappa index), of string capsule endoscopy (SCE) in the diagnosis of esophageal varices.

Screening of Barrett's esophagus with string-capsule endoscopy: a prospective blinded study of 100 consecutive patients using histology as the criterion standard.

Background: The yield of wireless capsule endoscopy for Barrett's esophagus (BE) has not been compared with its true criterion standard, histology.

Objective: To determine the sensitivity, specificity, positive predictive value, and negative predictive value of string capsule endoscopy (SCE) for the screening of BE by using specialized intestinal metaplasia as the criterion standard.

Design: Prospective, blinded, comparative study.

The yield and safety of string capsule endoscopy in patients with dysphagia.

Background: Dysphagia is a contraindication for the use of conventional capsule endoscopy (CE). Because string CE (SCE) allows for the immediate retrieval of the device, it eliminates the risk of capsule retention.

Objective: To assess the yield and safety of SCE in patients with dysphagia.

Feasibility and safety of string, wireless capsule endoscopy in the diagnosis of Barrett's esophagus.

Background: Capsule endoscopy is a major technological advancement in the visualization of the small bowell. Its utility in the evaluation of the esophagus is mainly limited by its rapid and unpredictable transmission, thus limiting the number of pictures of the esophagus, in particular, the distal esophagus.

Methods: Strings were attached to the wireless capsule endoscopy device to allow its controlled movement up and down the esophagus.

Feasibility and safety of string wireless capsule endoscopy in the diagnosis of esophageal varices.

Objective: To assess the feasibility, safety, accuracy, and acceptability of "string-capsule endoscopy" in the evaluation of esophageal varices.

Material And Methods: Strings were attached to the wireless capsule endoscopy device to allow its controlled movement up and down the esophagus. Time of recording and discomfort associated with the procedure was documented.

Outcomes of endoscopic treatment of gastroduodenal Dieulafoy's lesion with rubber band ligation and thermal/injection therapy.

Background: Dieulafoy's lesion is a rare but important cause of upper gastrointestinal bleeding. Current endoscopic methods used to treat Dieulafoy's lesion include injection, with or without thermal methods, and mechanical methods. The latter include variceal ligation and hemoclips.
