Sustainability in gastroenterology and digestive endoscopy: Position Paper from the Italian Association of Hospital Gastroenterologists and Digestive Endoscopists (AIGO).

Climate crisis is dramatically changing life on earth. Environmental sustainability and waste management are rapidly gaining centrality in quality improvement strategies of healthcare, especially in procedure-dominant fields such as gastroenterology and digestive endoscopy. Therefore, healthcare interventions and endoscopic procedures must be evaluated through the 'triple bottom line' of financial, social, and environmental impact.

Correct use of telemedicine in gastroenterology, hepatology, and endoscopy during and after the COVID-19 pandemic: Recommendations from the Italian association of hospital gastroenterologists and endoscopists (AIGO).

The purpose of the present document is to provide detailed information on the correct and optimal use of digital media to ensure continuity of care for gastroenterological patients in everyday clinical practice, in health emergencies and/or when the patient cannot reach the hospital for other reasons. During the recent COVID-19 pandemic, telemedicine has allowed many patients with chronic diseases to access remote care worldwide, proving to be the ideal solution to overcome restrictions and carry out non-urgent routine follow-ups on chronic patients. The COVID-19 pandemic has therefore made organizational and cultural renewal essential for the reorganization of healthcare in order to ensure greater continuity of care with a minimum risk of spreading the virus to users, practitioners and their families.

Could JC virus be linked to chronic idiopathic intestinal pseudo-obstruction?

JC virus is a member of the Polyomavirus family, infects humans worldwide, and 90% of the population carry antibodies to the virus by adult life. The initial infection is asymptomatic, but it may become persistent. JC virus DNA is frequently present in the upper and lower gastrointestinal tracts of healthy adults.

IBS clinical management in Italy: The AIGO survey.

Background: Irritable bowel syndrome (IBS) is the most frequent functional gastrointestinal disorder, both in primary and secondary care.

Aims: (1) To describe diagnostic tools and treatments suggested to IBS patients by Italian gastroenterologists; (2) To evaluate patients' quality of life and psychological involvement and the relationship of these factors with symptom severity.

Methods: Twenty-six gastroenterologists recorded the demographic and clinical data of 677 IBS patients.

A difficult diagnosis of coeliac disease: Repeat duodenal histology increases diagnostic yield in patients with concomitant causes of villous atrophy.

Villous atrophy in absence of coeliac disease (CD)-specific antibodies represents a diagnostic dilemma. We report a case of a woman with anaemia, weight loss and diarrhoea with an initial diagnosis of seronegative CD and a histological documented villous atrophy who did not improve on gluten-free diet due to the concomitant presence of common variable immunodeficiency (CVID) and Giardia lamblia infection. This case report confirms that CD diagnosis in CVID patients is difficult; the combination of anti-endomysial antibodies (EmA-IgA), anti-tissue transglutaminase antibodies (tTG-IgAb) antibodies and total IgA is obligatory in basic diagnostic of CD but in CVID are negative.

Is Epstein-Barr virus infection associated with the pathogenesis of microscopic colitis?

Background: Epstein-Barr virus (EBV) has been associated with inflammation in the colon, particularly in patients with inflammatory bowel disease (IBD). Even if a relevant plasmocytosis, similar to IBD, is present in microscopic colitis (MC), the frequency of EBV infection in this setting is unknown.

Objectives: We aimed to compare the frequency of colonic EBV infection in patients with MC, ulcerative colitis (UC), and irritable bowel syndrome (IBS).

Single versus two-operator endoscopic biliary cannulation technique: a multicenter matched-case analysis.

Background: The aim of this study was to compare the outcomes of physician-controlled, using both long and short endoscopic-retrograde-cholangiopancreatography wire systems, and assistant-controlled guide-wire biliary cannulation techniques, and to perform a literature review on this topic.

Methods: The endoscopic databases of three Endoscopic Centers were reviewed to identify all consecutive patients with an intact papilla who, between July 2013 and December 2014, underwent an endoscopic-retrograde-cholangiopancreatography. A total of 240 patients (80 for each group) were matched 1:1, by gender, age and indications for procedure and were included in the analysis.

Self-expandable metal stents for malignant colonic obstruction: data from a retrospective regional SIED-AIGO study.

Background: Self-expandable metal stents are a non-surgical option for the treatment of symptomatic malignant colorectal obstruction as palliative treatment or as a bridge to surgery.

Aims: To report data from a regional study on self-expandable metal stent (SEMS) placement for malignant colorectal obstruction.

Methods: Two hundred and four patients (male 54.

Delayed-onset superior mesenteric artery syndrome presenting as oesophageal peptic stricture.

Superior mesenteric artery (SMA) syndrome is an infrequent cause of vomiting and weight loss due to compression of the third part of the duodenum by the SMA. We describe the case of a 17-year-old woman, admitted to our department for progressive dysphagia and severe weight loss due to an oesophageal peptic stricture, caused by chronic acid reflux secondary to duodenal compression by the SMA. Symptoms improved after (par)enteral nutrition and repeated oesophageal dilatation, thus supporting the role of intensive medical and endoscopic intervention as an alternative to surgery, at least in some cases.

Efficacy and safety of endoscopic balloon dilation of symptomatic intestinal Crohn's disease strictures.

Aim: To evaluate prospectively the clinical efficacy and safety of endoscopic hydrostatic balloon dilation in a consecutive cohort of symptomatic intestinal Crohn's disease strictures.

Methods: Between September 2003 and December 2008 we performed endoscopic balloon dilations in 37 Crohn's disease patients with 39 intestinal symptomatic strictures (4 naïve and 35 postoperative). Dilations were performed using a Rigiflex through-the-scope balloon.

Music for colonoscopy: A single-blind randomized controlled trial.

Background: Several methods have been reported to minimize patient discomfort during colonoscopy, none are currently recommended by clinical practice guidelines. We performed a single-blind randomized controlled trial to assess the efficacy of music for colonoscopy.

Methods: 109 patients were randomized to music-delivering or mute headphones before and during colonoscopy.
