Abstract
OBJECTIVES In this study, we aimed at investigating the relationship between diverticula and in vivo colonic features such as total colon length (TCL), using CTC. We also evaluated polyps, neoplastic lesions and the correlation among them. METHODS This retrospective study considered a series of patients who underwent CTC in our Hospital from 2010 to 2018. We evaluated TCL, the length of each colon segments and sigmoid colon diameter using dedicated software. We verified the presence of diverticula, polyps and neoplasm and measured the number of diverticula using a five-point class scale, evaluating the colonic segments involved by the disease and the number of diverticula for each segment. A logistic regression model was used to analyse the relationship between diverticula and the patients' age, sigmoid colonic diameter and the length of each colonic segments. RESULTS The population finally included 467 patients, 177 males and 290 females (average age of 67 ± 12; range 45-96). The mean TCL was 169 ± 25 cm (range 115-241 cm). Out of the 467, 323 patients (69%) had at least one analyse. The patients with diverticula had a mean TCL significantly shorter than patients without diverticula (164 ± 22 vs 181 ± 27 cm; p = 0.001). Among the different variables, sigmoid colon length, sigmoid colon diameter and patient's age were correlated with diverticula (p < 0.01). Otherwise there is no association among diverticula, polyps and neoplasm. CONCLUSIONS The presence of colonic diverticula was significantly inversely correlated with TCL.The TCL was not significantly correlated with polyps and cancers. ADVANCES IN KNOWLEDGE The presence of colonic diverticula was significantly inversely correlated with total colon length, and in particular they significantly decreased with increasing colon length; our observation could contribute to the comprehension of diverticula pathogenesis.

Abstract
OBJECTIVES This study aimed to evaluate the prevalence of colonic diverticula according to age, gender, distribution, disease extension and symptoms with CT colonography (CTC). METHODS The study population included 1091 consecutive patients who underwent CTC. Patients with diverticula were retrospectively stratified according to age, gender, clinical symptoms and colonic segment involvement. Extension of colonic diverticula was evaluated using a three-point quantitative scale. Using this data, a multivariate regression analysis was applied to investigate the existence of any correlation among variables. RESULTS Colonic diverticula were observed in 561 patients (240 men, mean age 68 ± 12 years). Symptomatic uncomplicated diverticular disease (SUDD) was present in 47.4% of cases. In 25.6% of patients ≤40 years, at least one diverticulum in the colon was observed. Prevalence of right-sided diverticula in patients >60 years was 14.2% in caecum and 18.5% in ascending colon. No significant difference was found between symptomatic and asymptomatic patients regarding diverticula prevalence and extension. No correlation was present between diverticula extension and symptoms. CONCLUSION The incidence of colonic diverticula appears to be greater than expected. Right colon diverticula do not appear to be an uncommon finding, with their prevalence increasing with patient age. SUDD does not seem to be related to diverticula distribution and extension. KEY POINTS Incidence of colonic diverticula appears to be greater than expected. Right colon diverticula do not appear to be an uncommon finding. SUDD does not seem to be related to diverticula distribution and extension.

Abstract
Strictures of the colon can lead to significant morbidity requiring surgical management. The etiology of strictures is broad and generally categorized as benign, malignant, or pseudostrictures. Computed tomography (CT) is a crucial imaging modality in the assessment and characterization of colonic pathologies but colonoscopy remains the diagnostic gold standard. However, in the setting of incomplete colonoscopy due to strictures, the imaging features of CT will be relied on. This review will focus on the CT features of different colon pathologies leading to strictures and will be illustrated with images from 10 years of experience with CT colonography at our institutions from 2002-2012 (Hotel Dieu Hospital, Queen's University and Mount Sinai Hospital, University of Toronto).

Abstract
The statements produced by the Consensus Conference on Diverticular Disease promoted by GRIMAD (Gruppo Italiano Malattia Diverticolare, Italian Group on Diverticular Diseases) are reported. Topics such as epidemiology, risk factors, diagnosis, medical and surgical treatment of diverticular disease (DD) in patients with uncomplicated and complicated DD were reviewed by a scientific board of experts who proposed 55 statements graded according to level of evidence and strength of recommendation, and approved by an independent jury. Each topic was explored focusing on the more relevant clinical questions. Comparison and discussion of expert opinions, pertinent statements and replies to specific questions, were presented and approved based on a systematic literature search of the available evidence. Comments were added explaining the basis for grading the evidence, particularly for controversial areas.

Abstract
PURPOSE The purpose of this update article is to evaluate findings on CT colonography in patients with chronic diverticulitis and to compare the findings in patients with colorectal carcinoma. MATERIALS AND METHODS Different morphological criteria retrieved from a literature review were retrospectively analyzed in a series of 13 patients with proven chronic diverticulitis. The findings were compared with a series of 10 patients with colorectal carcinoma. RESULTS Overall, the findings in chronic diverticulitis resemble the findings in acute diverticulitis. The advantage of virtual CT colonography in differentiating both entities relies in the combination of morphological features previously described on axial computed tomography and double contrast barium enema. The single strongest morphological feature pointing towards the diagnosis of chronic diverticulitis is the presence of diverticula in the affected segment. In the presence of diverticula in the affected segment, a long segment (≥10 cm), thick fascia sign without adenopathies, mild bowel wall thickening, tapered margins, and distorted but preserved mucosal folds are likely to further improve accuracy of diagnosing chronic diverticulitis. CONCLUSION The single strongest morphological sign to differentiate chronic diverticulitis from colorectal cancer is the presence of diverticula in the affected segment.

Abstract
BACKGROUND Difficult and unstable endoscopic access to large sessile/flat colon polyps in the sigmoid colon may prevent successful and complete EMR. OBJECTIVE We report our experience with the use of an endoscopic cuff, a new endoscopic accessory, to improve endoscopic access during endoscopic therapy and scar assessment. DESIGN Single-center, retrospective, feasibility case series. SETTING Tertiary referral academic endoscopy unit. PATIENTS Nonconsecutive patients referred for endoscopic resection of large flat/sessile sigmoid colon polyps or surveillance of postpolypectomy scars in the sigmoid colon. INTERVENTIONS When conventional methods to achieve stable access and visualization were unsuccessful, the endoscopic cuff was used to retract sigmoid colon folds. MAIN OUTCOME MEASUREMENTS Safety, procedural success, and complications. RESULTS Five patients (mean age 62 years, 3 male/2 female) underwent endoscopic cuff-assisted EMR polypectomy, and 7 patients (mean age 62 years, 2 male/5 female) underwent post-EMR scar surveillance with an endoscopic cuff-assisted flexible sigmoidoscopy. All sessile/flat polyps (mean size 29 mm) or post-EMR scar sites (mean size 15 mm) were located at acute bends in the sigmoid colon. With the endoscopic cuff placed around the tip of the colonoscope, endoscopic access improved significantly by flattening/depressing colon folds close to the lesion/scar. The entire polyp/scar surface was revealed, facilitating a complete polyp excision and a meticulous scar assessment. No immediate or delayed adverse events were seen. LIMITATIONS Single-center, nonrandomized case series. CONCLUSIONS An endoscopic cuff appears to be a safe and easily used accessory to facilitate colonoscopic access for complex polypectomy and scar assessment in the sigmoid colon.

Abstract
OBJECTIVE Compare colonic distension and perceived burden of CT-colonography between participants receiving hyoscine butylbromide (buscopan) and glucagon hydrochloride as bowel relaxant. MATERIALS AND METHODS Data were collected within a screening trial. Participants received 20mg buscopan intravenously or 1mg of glucagon intravenously (if buscopan contra-indicated). Colon distension per segment was assessed using a 4-point scale (prone and supine). Data on perceived burden of CT-colonography were collected using a questionnaire two weeks after the examination. Outcome measures between groups were compared using propensity score matching. We used a stratified Wilcoxon-Mann-Whitney test statistic for quantitative and Cochran-Mantel-Haenszel statistics for categorical variables. RESULTS 541 participants were included: 336 (62%) received buscopan and 205 received glucagon. All buscopan recipients had an adequately distended colon, compared to 96% in the glucagon group (RR 7.31, 95% CI: 1.61-33.28). More glucagon recipients scored the insufflation as rather or extremely burdensome (25% vs. 16%; overall mean score 2.7 vs. 2.4; p<0.001) and more found the entire CT-colonography rather or extremely burdensome (14% vs. 7%; 2.2 vs. 1.9; p=0.001). Most frequently reported side effects were a dry mouth in the buscopan group (15%) and nausea in the glucagon group (13%). CONCLUSION Compared to glucagon, premedication with buscopan results in significantly more adequately distended colons and a less burdensome procedure. When buscopan can be used, it is the preferred bowel relaxant.

Abstract
The association of anisakiasis of the colon with colon cancer is rare and difficult to diagnose. Only one case of this type has been reported to date. In this study, we report a case of synchronous colon cancer and colonic anisakiasis. A 50-year-old woman was admitted for abdominal pain, and a volume-rendered surface-shaded image of CT colonography (CTC) revealed a concentric narrowing in the sigmoid colon and a segmental fold thickening in the ascending colon. A total colectomy was performed and the diagnosis of synchronous sigmoid colon cancer and anisakiasis of the ascending colon was confirmed. This case is the first reported visualization of synchronous colon cancer and colonic anisakiasis on a CTC.

Abstract
AIM To assess whether computed tomography colonography (CTC) is a viable alternative to colonoscopy or double contrast barium enema in the follow-up of patients after diverticulitis. MATERIAL AND METHODS Fifty patients underwent CTC followed immediately by colonoscopy. Results were blinded to the examiners. Findings of diverticular disease and patient acceptance were evaluated. RESULTS Bowel preparation and distension were good in the majority of CTC and colonoscopy examinations. Diverticular disease was found in 96% of patients at CTC and in 90% at colonoscopy. The rate of agreement between CTC and colonoscopy for diverticular findings in the sigmoid colon was good (kappa=0.64). No complications were seen. Patients found colonoscopy more uncomfortable (p<0.03), more painful (p<0.001), and more difficult (p<0.01) than CTC. Of the patients favouring one examination, 74% preferred CTC. CONCLUSION CTC appears to have a better diagnostic potential for imaging of diverticular disease-specific findings, when compared with colonoscopy. Also, CTC was less uncomfortable and was preferred by a majority of patients. CTC seems to be a reasonable alternative in follow-up of patients with symptomatic diverticular disease.
