The mobile cecum syndrome includes a spectrum of conditions. The cecal volvulus represents the acute form, with typical feature of a bowel obstruction that needs immediate operative treatment. On the other hand, a chronic form of mobile cecum syndrome which is the most common form reported a history of intermittent crampy abdominal pain, distension, and constipation. In this study, five patients came to our attention during the last ten years, presenting different symptoms due to a mobile cecum. All patients were investigated by several diagnostic techniques according to the specific clinical setting...

INTRODUCTION: Electronic virtual chromoendoscopy (EVC) can demonstrate ongoing disease activity in ulcerative colitis (UC), even when Mayo subscores suggest healing. However, applicability of EVC technology outside the expert setting has yet to be determined. METHODS: 15 participants across 5 centers reviewed a computerized training module outlining high-definition (HD) and EVC (i-Scan) colonoscopy modes. Interobserver agreement was then tested (Mayo score, UCEIS and the Paddington International virtual ChromoendoScopy ScOre [PICaSSO] for UC), using a colonoscopy video library (n=30 cases reviewed pre- and n=30 post-training)...

BACKGROUND: Colonoscopy plays an important role in the clinical screening and management of colorectal cancer. The traditional 'see one, do one, teach one' training style for such invasive procedure is resource intensive and ineffective. Given that colonoscopy is difficult, and time-consuming to master, the use of virtual reality simulators to train gastroenterologists in colonoscopy operations offers a promising alternative. METHODS: In this paper, a realistic and real-time interactive simulator for training colonoscopy procedure is presented, which can even include polypectomy simulation...

The present paper describes a case of ileocecal intussusception detected by ultrasound and confirmed by CT, including the imaging characteristics allowing its diagnosis. The patient was referred for colonoscopy, which could not be completed, to assess the cause of intussusception. Then it was decided to resort to Virtual colonoscopy, which allowed to identify and characterize a cecal neoplasm serving as a lead point for the intussusception.

OBJECTIVES: Dye spraying chromoendoscopy (DCE) is recommended for the detection of colonic neoplastic lesions in inflammatory bowel disease (IBD). The majority of neoplastic lesions are visible endoscopically and therefore targeted biopsies are appropriate for surveillance colonoscopy. To compare three different techniques for surveillance colonoscopy to detect colonic neoplastic lesions in IBD patients: high definition (HD), (DCE), or virtual chromoendoscopy (VCE) using iSCAN image enhanced colonoscopy...

PURPOSE: Virtual colonoscopy is the most recently developed tool for detecting colorectal cancers and polyps, but its effectiveness is limited. In our study, we compared the result of preoperative virtual colonoscopy to result of preoperative and postoperative colonoscopy. We evaluated also the accuracy of preoperative virtual colonoscopy in patients who had obstructive colorectal cancer that did not allow passage of a colonoscope. METHODS: A total of 164 patients who had undergone preoperative virtual colonoscopy and curative surgery after the diagnosis of a colorectal adenocarcinoma between November 2008 and August 2013 were pooled...

BACKGROUND: The effectiveness of colonoscopy for diagnosing and preventing colon cancer is largely dependent on the ability of endoscopists to fully inspect the colonic mucosa, which they achieve primarily through skilled manipulation of the colonoscope during withdrawal. Performance assessment during live procedures is problematic. However, a virtual withdrawal simulation can help identify and parameterise actions linked to successful inspection, and offer standardised assessments for trainees...

CT colonography is a CT examination focused on the detection of colonic polyps and masses. Its most common indications include incomplete optical colonoscopy and generally personal preference in symptomatic or frail patients. CT colonography has a diagnostic yield similar to optical colonoscopy. It is less demanding for the patient, has shorter examination times, lower rates of adverse effects (including bowel perforation) and allows limited evaluation of extracolonic structures. In 10-15 % of asymptomatic patients, optical colonoscopy is needed if either a colonic polyp or mass is detected...
