Short and long-term outcomes of underwater EMR compared to the traditional procedure in the real clinical practice.

Background And Aims: underwater endoscopic mucosal resection (U-EMR) has been recently described as an alternative to endoscopic mucosal resection (EMR) for flat colorectal polyps. However, the real applications remain unclear due to the lack of comparative studies.

Methods: a multi-centric prospective study was performed from November 2016 to December 2017.

Multiband mucosectomy for the treatment of challenging non-pedunculated colorectal polyps.

Background And Study Aims: Endoscopic mucosal resection is the gold standard treatment for non-pedunculated colorectal polyps; however, some specific situations (location behind folds, scarred or flat morphology) can make this technique challenging. We aimed to assess the efficacy and safety of multiband mucosectomy (MBM) for resection of non-pedunculated colorectal polyps.

Patients And Methods: This was a retrospective study of patients in whom MBM was performed to resect large non-pedunculated colorectal polyps.

Underwater hybrid endoscopic submucosal dissection in a rectal polyp: a case report of a new application of "underwater endoscopy".

Background: Hybrid endoscopic submucosal dissection (ESD) has been described as an alternative to traditional ESD. This technique is less time consuming, but the en bloc resection rate is lower than in ESD. Similar to endoscopic mucosal resection, the underwater technique could improve preliminary disadvantages of hybrid ESD.

Actinomyces infection as a complication of a post-radiotherapy rectal ulcer.

Introduction: Pelvic radiotherapy is associated with early and late local complication. Actinomyces bacterium is part of the saprophyte flora, although some infection underlying factors are known , the pathophysiology of the disease is still unexplained. Frequently it is involved in oral, gastrointestinal and respiratory infections.

Accuracy of liquid cytology in the diagnosis and monitoring of eosinophilic oesophagitis.

Background: Oesophagoscopy with biopsy is considered the gold standard for diagnosing and monitoring eosinophilic oesophagitis (EoE). Therefore is important to discover less-invasive diagnostic methods.

Methods: Cytology specimens were obtained in patients with active EoE (AEoE) (≥15 eos/hpf) and EoE in remission (EoER) (<15 eos/hpf).

[Adult celiac disease and intraepithelial lymphocytes. New options for diagnosis?].

Background: Permanent changes have been found in intraepithelial lymphocyte (IEL) subsets in patients with celiac disease.

Objective: The main aim of this study was to demonstrate the utility of determining CD3()/CD7(+) and T cell receptor (TCR) gamma-delta IEL subsets by flow cytometry as a diagnostic marker of adult celiac disease.

Patients And Methods: We performed a prospective study in a sample of 128 adult patients (70 with celiac disease and 58 controls).
