Colonoscopy Surveillance After Colorectal Cancer Resection: Recommendations of the US Multi-Society Task Force on Colorectal Cancer.Kahi CJ, Boland CR, Dominitz JA, Giardiello FM, Johnson DA, Kaltenbach T, Lieberman D, Levin TR, Robertson DJ, Rex DK. Gastroenterology. 2016 Mar;150(3):758-768.

The US Multi-Society Task Force has developed updated recommendations to guide health care providers with the surveillance of patients after colorectal cancer (CRC) resection with curative intent. This document is based on a critical review of the literature regarding the role of colonoscopy, flexible sigmoidoscopy, endoscopic ultrasound, fecal testing and CT colonography in this setting.

British Society of Gastroenterology/Association of Coloproctologists of Great Britain and Ireland guidelines for the management of large non-pedunculated colorectal polyps . Matthew D Rutter,  Amit Chattree, Jamie A Barbour,  Siwan Thomas-Gibson,  Pradeep Bhandari,  Brian P Saunders,  Andrew M Veitch,  John Anderson,  Bjorn J Rembacken,  Maurice B Loughrey,  Rupert Pullan,  William V Garrett,  Gethin Lewis,  Sunil Dolwani.

These guidelines provide an evidence-based framework for the management of patients with large non-pedunculated colorectal polyps (LNPCPs), in addition to identifying key performance indicators (KPIs) that permit the audit of quality outcomes. These are areas not previously covered by British Society of Gastroenterology (BSG) Guidelines.

Endoscopy in patients on antiplatelet or anticoagulant therapy, including direct oral anticoagulants: British Society of Gastroenterology (BSG) and European Society of Gastrointestinal Endoscopy (ESGE) guidelines.    Andrew M Veitch, Geoffroy Vanbiervliet, Anthony H Gershlick, Christian Boustiere, Trevor P Baglin, Lesley-Ann Smith, Franco Radaelli, Evelyn Knight, Ian M Gralnek, Cesare Hassan, Jean-Marc Dumonceau.

The risk of endoscopy in patients on antithrombotics depends on the risks of procedural haemorrhage versus thrombosis due to discontinuation of therapy.P2Y12 receptor antagonists (clopidogrel, prasugrel, ticagrelor) For low-risk endoscopic procedures we recommend continuing P2Y12 receptor antagonists as single or dual antiplatelet therapy (low quality evidence, strong recommendation); For high-risk endoscopic procedures in patients at low thrombotic risk, we recommend discontinuing P2Y12 receptor antagonists five days before the procedure (moderate quality evidence, strong recommendation). In patients on dual antiplatelet therapy, we suggest continuing aspirin (low quality evidence, weak recommendation).

American Gastroenterological Association Institute Technical Review on the Management of Acute Diverticulitis. Lisa L. Strate, Anne F. Peery,  Ignacio Neumann.  Gastroenterology  Published Online: October 07, 2015

Diverticulosis is a condition in which sac-like protrusions develop in the wall of the colon. The prevalence of diverticulosis increases with age; less than 20% of people younger than 40 years of age are noted to have diverticulosis on colonoscopy, compared with more than 60% of people older than 70 years of age.

Background.Microscopic colitis (MC) is an underdiagnosed inflammatory bowel disease.Aim.To develop an evidence-based clinical practice guide on MC current concepts.Methods.Literature search was done on the Cochrane Library, EMBASE and MEDLINE electronic databases, which were consulted covering the period up until March 2015. Work groups were selected for each of the reviewed topics, with the purpose of drafting the initial statements and recommendations.
