Abstract
Gastrointestinal disease is prevalent and broad, manifesting itself in a variety of ways, including inflammation, fibrosis, infection, and cancer. However, historically, diagnostic technologies have exhibited limitations, especially with regard to diagnostic uncertainty. Despite development of newly emerging technologies such as optoacoustic imaging, many recent advancements have focused on improving upon pre-existing modalities such as ultrasound, computed tomography, magnetic resonance imaging, and endoscopy. These advancements include utilization of machine learning models, biomarkers, new technological applications such as diffusion weighted imaging, and new techniques such as transrectal ultrasound. This review discusses assessment of disease processes using imaging strategies for the detection and monitoring of inflammation, fibrosis, and cancer in the context of gastrointestinal disease. Specifically, we include ulcerative colitis, Crohn's disease, diverticulitis, celiac disease, graft vs. host disease, intestinal fibrosis, colorectal stricture, gastric cancer, and colorectal cancer. We address some of the most recent and promising advancements for improvement of gastrointestinal imaging, including unique discussions of such advancements with regard to imaging of fibrosis and differentiation between similar disease processes.

Abstract
Left-sided colonic diverticulitis is a common condition with significant morbidity and health care costs in Western countries. Acute uncomplicated diverticulitis which is characterized by the absence of organ dysfunction, abscesses, fistula, or perforations accounts for around 80% of the cases. In the last decades, several traditional paradigms in the management of acute uncomplicated diverticulitis have been replaced by evidence-based routines. This review provides a comprehensive evidence-based and clinical-oriented overview of up-to-date diagnostics with computer tomography, non-antibiotic treatment, outpatient treatment, and surgical strategies as well as follow-up of patients with acute uncomplicated diverticulitis.

Abstract
BACKGROUND There are currently no guidelines on the management of right colon diverticulitis. Treatment options have been extrapolated from the management of left-sided diverticulitis. Gaining knowledge of the risk and morbidity of diverticulitis recurrence is integral to weighing the benefit of elective surgery for right-sided diverticulitis. OBJECTIVE The purpose of this study was to summarize the recurrence rate and the morbidity of recurrence of Hinchey classification I/II, right-sided diverticulitis following nonoperative management. DATA SOURCES PubMed, EMBASE, and Cochrane Database of Collected Reviews were searched up to June 2019. STUDY SELECTION Observational cohort studies evaluating outcomes following nonoperative management were reviewed. No randomized controlled trials were available. INTERVENTIONS Intravenous antibiotics with or without percutaneous drainage of associated abscess were administered. MAIN OUTCOME MEASURES The primary outcomes measured were the recurrence rate and morbidity associated with recurrence. Two independent investigators extracted data. The rates of recurrence were pooled by using a random-effects model. RESULTS There were 1584 adult participants from a total of 11 studies (9 retrospective cohort and 2 prospective cohort studies) included in the analysis. Over a median follow-up period of 34.2 months, the pooled recurrence rate was 12% (95% CI, 10%-15%). Twenty of 202 patients (9.9%) required urgent surgery at the time of first recurrence. There was no mortality. Subset analysis excluding 3 studies that included percutaneous drainage as a nonoperative treatment option did not change the recurrence rate (12% (95% CI, 9%-15%)) or heterogeneity. Funnel plot assessment revealed no publication bias. LIMITATIONS There were no randomized controlled trials available. The statistical heterogeneity was moderate (I = 46%). CONCLUSIONS Nonoperative management of Hinchey I/II right-sided diverticulitis is safe and feasible. The recurrence rate is relatively low, and complications that require urgent operation are uncommon. PROSPERO CRD42019131673.

Abstract
Left lower quadrant pain is a frequent indication for imaging in the emergency department. Most causes of pain originate from the colon, including diverticulitis, colitis, fecal impaction, and epiploic appendagitis. Left-sided urolithiasis and spontaneous hemorrhage in the retroperitoneum or rectus sheath are additional causes of pain. Computed tomography is the preferred imaging modality in the emergent setting for all of these pathologic conditions. Gynecologic, testicular, and neoplastic pathology may also cause left lower quadrant pain but are not discussed in this article.

Abstract
PURPOSE Most patients with acute right colonic uncomplicated diverticulitis can be managed conservatively. The aim of this study was to assess the clinical and radiologic risk factors for recurrence in patients with right colonic uncomplicated diverticulitis. METHODS The present survey included 469 patients who were successfully managed conservatively for the first episode of right colonic uncomplicated diverticulitis between 2002 and 2012 in a referral center, and records were reviewed from collected data. Patients were divided into two groups: a nonrecurrent and a recurrent group. The clinical and radiologic features of all patients were analyzed to identify possible risk factors for recurrence. The Kaplan-Meier method and Cox regression were used. RESULTS Seventy-four (15.8 %) patients had recurrence, and 15 (3.2 %) received surgery at recurrence within a median follow-up of 59 months. The mean recurrence interval after the first attack was 29 months. In univariate and multivariate analyses, risk factors for recurrence were confirmed multiple diverticula (relative risk [RR], 2.62; 95 % confidence interval [CI], 1.56-4.40) and intraperitoneally located diverticulitis (RR, 3.73; 95 % CI, 2.13-6.52). Of 66 patients with two risk factors, 36 (54.5 %) had recurrence and 10 (15.2 %) received surgery at recurrence. CONCLUSIONS In patients with right colonic uncomplicated diverticulitis who have multiple diverticula and intraperitoneally located diverticulitis, the possibility of recurrence and surgical rate are high. Poor outcome may be cautioned in these patients.

Is early colonoscopy beneficial in patients with CT-diagnosed diverticulitis? AJR Am J Roentgenol 2013; 200:1269-74. [PMID: 23701063 DOI: 10.2214/ajr.12.9539] [Citation(s) in RCA: 41] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/15/2022]
Abstract
OBJECTIVE The purpose of this study was to establish CT criteria as an indication for colonoscopy in patients with acute diverticulitis. MATERIALS AND METHODS The study was composed of patients diagnosed with acute diverticulitis on contrast-enhanced CT (CECT) from January 2000 to December 2004. Patients without subsequent colonoscopy were excluded. Findings on CT were correlated with patient outcomes over follow-up. Sensitivity, specificity, and predictive values of the imaging parameters for prediction of colon cancer were calculated. Outcomes were also compared between men and women. RESULTS Of 1034 patients with a CT diagnosis of diverticulitis, 402 (235 women and 167 men; mean age, 63.3 years) had available endoscopic colonic evaluation after CECT. The mean follow-up was 5.3 years. Seventy-eight patients had polyps (71% adenomatous) and nine patients (2.2%) were diagnosed with colon cancer (seven women, two men). The odds ratio for diagnosis of colon cancer was 23.35 in patients with mesenteric or retroperitoneal lymphnodes, 4.67 for abscess, and 24.43 in patients with obstruction and localized mass reported on CT. A significant correlation was found between the location of diverticulitis and cancer (p < 0.001). The diagnosis of cancer was made within 6 months from the date of CECT in eight patients. The odds of cancer were 2.5 times higher in women. CONCLUSION On the basis of the significant correlation of complicated diverticulitis or presence of lymph nodes with new diagnoses of colon cancer, we recommend early colonoscopy in patients with wall thickness more than 6 mm, abscess, obstruction, or lymph nodes seen on CECT.

Abstract
This prospective study aims to evaluate the efficacy of multislice computed tomography combined with colon distension by water enteroclysis (MSCTe) in determining the presence and depth of bowel endometriotic lesions. Ninety-eight women with symptoms suggestive of colorectal endometriosis underwent MSCTe; locations, number of nodule/s, size of the nodule/s and depth of bowel wall infiltration were determined. Independently from the findings of MSCTe, all women underwent laparoscopy. MSCTe findings were compared with surgical and histological results. Abnormal findings suggestive of bowel endometriotic nodules were detected by MSCTe in 75 of the 76 patients with bowel endometriosis. MSCTe identified 110 (94.8%) of the 116 bowel endometriotic nodules removed at surgery; 6 nodules missed at MSCTe were located on the rectum. MSCTe correctly determined the degree of infiltration of the bowel wall in all of the 34 serosal bowel nodules identified at MSCTe. In six nodules reaching the submucosa, the depth of infiltration was underestimated by MSCTe. MSCTe had a sensitivity of 98.7%, a specificity of 100%, a positive predictive value of 100% and a negative predictive value of 95.7% in identifying women with bowel endometriosis. MSCTe is effective in determining the presence and depth of bowel endometriotic lesions.

Abstract
Magnetic resonance imaging (MRI) is rapidly emerging as a useful imaging modality for the evaluation of the gastrointestinal tract. Increasingly rapid sequences and improving hardware have significantly improved the visualisation of diseases of the colon. MRI has a major advantage over CT in that there is no ionising radiation. In our institution, MRI has increasingly been used as a complimentary imaging modality to CT in the diagnosis and evaluation of diverticulitis and its complications. In this review article, we illustrate the emerging role of MRI in the diagnosis and evaluation of colonic diverticulitis.

Abstract
PURPOSE This review shows the diagnostic potential of computed tomography (CT) in the diagnosis and differential diagnosis of acute left-sided colonic diverticulitis. METHODS Using a single detector spiral CT, standard examination of the entire abdomen is performed after oral and rectal administration of diluted iodinated contrast medium with collimation of 8 mm, pitch of 1.5, and reconstruction increment of 8 mm before and after intravenous contrast injection. Intravenous administration of spasmolytic agents, various patient positions, and the thin-section technique with 3-5 mm slices are beneficial in difficult cases. RESULTS The differential diagnosis of acute left-sided colonic diverticulitis includes tumorous, inflammatory, and ischemic diseases of the colon as well as infarctions of epiploic appendages and the omentum majus. The knowledge of the various CT criteria of acute colonic diverticulitis and their differential diagnoses helps to establish a correct diagnosis in a wide majority of cases. CONCLUSION At present, CT is the diagnostic procedure of choice for assessing acute diverticulitis. Distinct knowledge of the CT features helps to differentiate the various entities accurately.
