Meckel´s diverticulum bleeding detected by capsule endoscopy.

A 28-year-old man diagnosed with Charge syndrome and no history of NSAIDs ingestion was referred due to the presentation in the previous 24 h of melenic stools with a negative upper endoscopy. Physical examination was unremarkable, although laboratory tests showed anemia. On the second day, significant painless rectal bleeding and the decrease of hematocrit levels responding to blood transfusion were observed, so colonoscopy was recommended but completely rejected by the patient. Therefore, capsule endoscopy was performed, identifying a saccular image in the terminal ileum suggestive of a Meckel's diverticulum.

Practical aspects of high resolution esophageal manometry.

High resolution esophageal manometry (HRM) is currently under development as can be seen in the various Chicago classifications. In order to standardize criteria in certain practical aspects with limited scientific evidence, the First National Meeting for Consensus in High Resolution Manometry of the Spanish Digestive Motility Group took place, bringing together a wide group of experts. The proposals were based on a prior survey composed of 47 questions, an exhaustive review of the available literature and the experience of the participants. Methodological aspects relating to the poorly defined analysis criteria of certain new high resolution parameters were discussed, as well as other issues previously overlooked such as spontaneous activity or secondary waves. Final conclusions were drawn with practical applications.

Endoscopic mucosal resection for proximal superficial lesions: efficacy and safety study in 59 consecutive resections.

INTRODUCTION: endoscopic mucosal resection is an accepted technique for the treatment of proximal gastrointestinal tract superficial lesions. OBJECTIVES: to evaluate the efficacy and safety of this procedure in the proximal gastrointestinal tract. MATERIAL AND METHODS: forty one consecutive patients (23 males and 18 females, mean age of 61 ± 11.5 years) were included in our study. Fifty nine resections were performed in these patients in 69 sessions. Lesions treated consisted of elevated lesions with high grade dysplasia in the context of Barrett's esophagus (group A), high grade dysplasia appearing in random biopsies taken during the follow-up of Barrett's esophagus (group B) and superficial gastroduodenal lesions (group C). Snare resection after submucosal injection, band ligator-assisted or cap-assisted mucosal resection were the chosen techniques. RESULTS: we resected 7 elevated lesions with high grade dysplasia in the context of Barrett's esophagus, 6 complete Barrett's esophagus with high grade dysplasia in 16 sequential sessions and 46 gastroduodenal superficial lesions (10 adenomas, 9 gastric superficial carcinomas, 18 carcinoid tumours and 9 lesions of different histological nature). Resections in the two first groups were complete in 100% of the cases, and in 97.9% of the cases in group C. Complications included 2 cases of limited deferred bleeding (groups A and B) and another two cases of stenosis with little clinical relevance in Group B. CONCLUSIONS: a) endoscopic mucosal resection is an efficient technique for the treatment of proximal gastrointestinal tract superficial lesions; b) it is a safe procedure with a low percentage of complications, which can generally be managed endoscopically; and c) in contrast with other ablative techniques, endoscopic mucosal resection offers the possibility of a pathologic analysis of the samples.
