Cat scratch esophagus.

The cat scratch esophagus is an uncommon entity. The first case described in the literature of this type of lesions was published in 2007 and was located in the colon. There are two cases described in the esophagus, this has been the first detected by endoscopic capsule.

Eosinophilic esophagitis after an episode of herpetic esophagitis.

We want to present a case of eosinophilic esophagitis (EoE) after a herpetic esophagitis (HE) to increase the available evidence on the association suggested between both entities recently published by Iriarte Rodríguez et al.

Impact of the endoscopist's experience on the negative predictive value of capsule endoscopy.

Introduction: The impact of the accumulated experience of the capsule endoscopy (CE) reader on the accuracy of this test is discussed.

Aim: To determine whether the negative predictive value of CE findings changes along the learning curve.

Methods: We reviewed the first 900 CE read by 3 gastroenterologists experienced in endoscopy over 8 years.

Diffuse intestinal ganglioneuromatosis an uncommon manifestation of Cowden syndrome.

Diffuse intestinal ganglioneuromatosis is a hamartomatous polyposis characterized by a disseminated, intramural or transmural proliferation of neural elements involving the enteric plexuses. It has been associated with MEN II, neurofibromatosis type 1 and hamartomatous polyposis associated with phosphatase and tensin homolog mutation. We report the case of a female patient with a history of a breast and endometrial tumor who presented in a colonoscopy performed for rectal bleeding diffuse ganglioneuromatosis, which oriented the search for other characteristic findings of Cowden syndrome given the personal history of the patient.

[Comparison between insufflation with air or carbon dioxide during the colonoscopy in sedated patients with propofol].

Objectives: compare the intensity of pain experienced after colonoscopy with air or with CO₂ and evaluate the safety of CO₂ in colonoscopies performed with moderate/deep sedation.

Materials And Methods: individuals undergoing ambulatory colonoscopy without exclusion criteria (severe respiratory disease, morbid obesity) were randomized in air or CO₂ group. We recorded different variables prior to, during and upon completion of the colonoscopy, performing monitoring using pulse oximetry and capnography.
