Magnetic Resonance Imaging for the diagnosis and management of acute colonic diverticulitis: a review of current and future use. J Med Radiat Sci 2021; 68:310-319. [PMID: 33607699 PMCID: PMC8424307 DOI: 10.1002/jmrs.458] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2020] [Revised: 12/29/2020] [Accepted: 12/31/2020] [Indexed: 12/14/2022] Open
Abstract
Diverticular disease is one of the most common causes of outpatient visits and hospitalisations across Australia, North America and Europe. According to the Gastroenterological Society of Australia (GESA, 2010), approximately 33% of Australians over 45 years of age and 66% over 85 years of age have some form of colonic diverticulosis. Patients with colonic diverticulosis are known to develop subsequent complications such as acute colonic diverticulitis (ACD), and when more than one attack of diverticulitis occurs, there is a 70-90% chance that the individual will experience ongoing problems and recurring infections throughout their lifetime. Medical imaging is fundamental in the diagnosis, treatment and ongoing management of ACD and its complications, with Computed Tomography (CT) identified as the prevailing gold standard in the last few decades. Cross-database searching highlighted a large gap in the literature regarding the effectiveness of Magnetic Resonance Imaging (MRI) as a non-ionising radiation alternative imaging tool for ACD imaging after the mid-2000s, despite ongoing technological advancements in this modality. This narrative review identified 13 key publications (11 primary prospective cohort studies, 1 systematic review and 1 meta-analysis) that evaluate MRI for ACD imaging, of which five were published within the last decade. Several existing MRI protocols are deemed suitable for ACD imaging, and it is recommended they be re-evaluated in larger cohorts. Future studies should consider the rapidly growing technological improvements of MRI, its cost efficiency and its applicability in modern day healthcare settings when addressing ACD management. This is especially important considering the gradual rise in radiation dose among the Australian population attributable to increased CT referrals, alongside increased reporting of ACD cases in younger individuals.

Ultrasound can differentiate complicated and noncomplicated acute colonic diverticulitis: a prospective comparative study with computed tomography. Abdom Radiol (NY) 2021; 46:3826-3834. [PMID: 33765176 DOI: 10.1007/s00261-021-03060-5] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2021] [Revised: 03/06/2021] [Accepted: 03/10/2021] [Indexed: 01/02/2023]
Abstract
OBJECTIVE To prospectively assess the diagnostic value of intestinal ultrasound (US) compared to computerized tomography (CT) in differentiating uncomplicated and complicated acute colonic diverticulitis (ACD). MATERIALS AND METHODS During a period of 14 months patients referred to the department of Radiology with clinical suspicion of ACD underwent an US examination. All confirmed US ACD diagnosis were included and subsequently underwent an emergency abdominal CT, used as gold standard. The WSES (World Society for Emergent Surgery) classification of diverticulitis was used. Diverticulitis was prospectively classified as either uncomplicated or complicated. Sensitivity, specificity, positive predictive value, and negative predictive values of US were evaluated. Before CT scan, the radiologist indicated whether they would have required or not a complementary CT scan, based on US findings. RESULTS Of the 240 patients included in our study, 71 (29.6%) were Stage 0, 127 (53%) Stage 1A, and 42 (17.5%) were moderate-severe ACD (stages 1B, 2A, 2B, 3 and 4). The sensitivity of US for diagnosing complicated ACD was 84% and specificity of 95.8%. Most patients (24 of 27) misclassified by US as uncomplicated diverticulitis were classified on CT as stage 1A. From the 148 cases in which the radiologist considered CT unnecessary, only 3 of these revealed signs of complicated ACD on CT; none of them required emergency surgery. CONCLUSION US is an effective technique to differentiate complicated from uncomplicated ACD. Our results suggest that US, may be a valuable alternative to CT for the initial radiologic evaluation in patients with clinical suspicion of ACD.

ACTA ACUST UNITED AC 2021; 57:medicina57070682. [PMID: 34356963 PMCID: PMC8305485 DOI: 10.3390/medicina57070682] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Revised: 06/30/2021] [Accepted: 07/01/2021] [Indexed: 11/30/2022]
Abstract
Background and Objectives: Colonoscopy following an episode of acute diverticulitis is currently recommended to rule out underlying colon cancer. However, a number of studies have debated this recommendation. We aimed to explore whether patients with colonic diverticulosis who experienced an episode of acute diverticulitis had higher prevalence colonic pathologies, essentially colonic adenomas and colorectal carcinoma (CRC) on a follow-up colonoscopy. Materials and Methods: We performed a multicenter retrospective study that included patients with a diagnosis diverticulosis as the control group and allocated patients after diverticulitis according to computed tomography (CT) scan and clinical presentation that had performed colonoscopy within 6 months from the acute diverticulitis episode. We compared the detection rate of colonic pathologic findings in both groups. Results: Overall, 367 patients were included. Of them, 134 patients experienced an episode of diverticulitis vs. 233 patients who did not have diverticulitis. On univariate analysis, there was no difference between all pathological findings (CRC, colonic adenomas; OR (odds ratio) 1.51, p = 0.085), and even for each pathological findings alone, there was no difference (for colonic adenomas, p = 0.07; for CRC, p = 0.87). Further sub-analysis revealed that only male gender (OR 4.03, p = 0.004) and smoking (OR 8.67, p < 0.0001) correlated with colonic adenomas and CRC, while moderate to severe disease was not correlated with colonic pathological findings (OR 0.86, 95% CI (confidence interval) 0.4–1.82, p = 0.68). Conclusions: Post-diverticulitis screening colonoscopy has not found a higher rate of colonic pathological findings, especially colonic neoplasia. Decision to perform colonoscopy after acute diverticulitis should be individualized based on risk stratification of colonic neoplasia.

Radiologic predictors for failure of non-operative management of complicated diverticulitis: a single-centre cohort study. Langenbecks Arch Surg 2021; 406:2409-2418. [PMID: 34189654 PMCID: PMC8578075 DOI: 10.1007/s00423-021-02244-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Accepted: 06/11/2021] [Indexed: 02/05/2023]
Abstract
Purpose Modern non-operative management of diverticulitis consists of a complex therapeutic regimen and is successful in most cases even of complicated diverticulitis. Still, a certain proportion of patients requires urgent surgery due to failure of the conservative approach. This study aims to identify predictors for failure of conservative treatment of complicated diverticulitis with the need for subsequent urgent resection during the acute episode. Methods A single-centre retrospective cohort study was performed at our tertiary centre including cases of acute complicated diverticulitis (characterized by localized abscess formation and/or pericolic air) between 2007 and 2019 that were treated guideline-conform by multimodal conservative treatment. Radiologic characteristics of disease in CT scans upon admission were analysed by uni- and multivariable logistic regression to determine predictors for resection within 30 days after onset of the conservative therapy approach. Results A total of 669 cases of acute diverticulitis were identified, of which 141 patients met the inclusion criteria. Overall, 13% (n = 19) of patients were operated within 30 days despite initial conservative management. Multivariable logistic regression identified length of inflamed bowel greater than 7 cm (p < 0.011) and abscess formations >1 cm (p < 0.001) as significant risk factors for failure of conservative treatment. Conclusion Patients with length of inflamed bowel >7 cm or abscess formation >1 cm have increased risk for failure of conservative treatment of acute episodes of diverticulitis with contained perforations with subsequent need for urgent surgery. Therefore, conservative treatment of those patients should be monitored with special caution.

Accuracy of preoperative CT staging of acute colonic diverticulitis using the classification of diverticular disease (CDD) - Is there a beneficial impact of water enema and visceral obesity? Eur J Radiol 2021; 141:109813. [PMID: 34116453 DOI: 10.1016/j.ejrad.2021.109813] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Revised: 05/13/2021] [Accepted: 06/02/2021] [Indexed: 11/18/2022]
Abstract
PURPOSE We evaluated the accuracy of preoperative CT in staging colonic diverticulitis (ACD) by using the classification of diverticular disease (CDD) and investigated the diagnostic impact of water enema (WE) and visceral obesity. METHODS In this retrospective study, the radiological and hospital information system was searched for patients who underwent CT for clinically suspected ACD prior to surgery between 2009 and 2019. From the initial population (n = 164), we included 155 patients (94.5 %) (85 women; mean age: 58 ± 13 years) matching the following inclusion criteria: i.) clinically suspected ACD, ii.) i.v. contrast-enhanced CT, iii.) surgery for ACD within 1 week after CT, iv.) histopathological report that proved ACD. The remaining 9 patients (5.5 %) were excluded because histopathological reports were lacking (n = 3) or CT was performed without intravenous contrast agent (n = 6). WE (+ butylscopolamine i.v.) was performed in 93 patients (group A, 60 %). 62 patients (group B, 40 %) had no WE. Visceral-to-subcutaneous fat ratio (V/S) was determined for each patient. Two radiologists blinded for final diagnosis independently staged ACD according to CDD and assessed prevalence and confidence ratings of ACD-related CT-findings: pericolonic fat stranding, covered- and free-perforation, local and generalized peritonitis, abscess. Interobserver-agreement of CT-findings were assessed and effects of WE and V/S ratio on the diagnostic accuracy of CT with surgical and histopathological findings as reference were determined by calculating a logistic regression model. RESULTS CT-staging showed high accuracy (94 %) and excellent interrater-correlation (ICC 0.96) for staging ACD. WE had no positive impact neither on diagnostic accuracy of staging, nor on confidence ratings of ACD-related CT-findings (all p > 0.5). Confidence ratings were significantly higher in examinations without WE for perforation, peritonitis as well as abscesses (all p < 0.5). Confidence ratings for the assessment of local peritonitis improved significantly with higher V/S (p = 0.049). The increase of V/S significantly correlated with the probability for correct CDD staging of ACD in CT (p = 0.023). CONCLUSION Increase of visceral obesity significantly improves accuracy of CT in preoperative staging acute colonic diverticulitis. However, independently of the degree of visceral obesity, water enema has no diagnostic benefit and may therefore be omitted. Overall, CT proves high accuracy in preoperative staging ACD using the classification of diverticular disease. LEVEL OF EVIDENCE Retrospective study, observational study.

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
PURPOSE To evaluate the frequency with which patients with an urgent health concern, specifically diverticulitis, avoided appropriate medical care during the early weeks of the coronavirus pandemic of 2020 and to study the consequences of the resultant delay in care, the incidence of an associated abscess. METHODS This study was institutional review board approved. Reports for CT studies with findings of newly diagnosed diverticulitis within Henry Ford Health System during the early weeks of the coronavirus pandemic of 2020 were reviewed and compared with the same time period in 2019. Total cases of diverticulitis on CT were compared, as well as the prevalence of an associated abscess. A chi-squared analysis was performed to determine the statistical significance of the percentage of patients presenting with an abscess in each year. RESULTS During the early weeks of the coronavirus pandemic, 120 patients were identified with CT findings of newly diagnosed diverticulitis with 11.7% of those patients (14 patients) presenting with an associated abscess. During the same time period in 2019, many more CT studies with newly diagnosed diverticulitis were obtained (339), and, compared to 2020, less than half the percentage of those patients had an associated abscess (4.4% or 15 patients). CONCLUSION Patients with urgent health concerns avoided appropriate and necessary care during the early weeks of the coronavirus pandemic. While non-COVID-19 emergency visits were diminished, patients who did present with diverticulitis were more likely to present with greater disease severity as manifested by an associated abscess. Patients must be encouraged to seek care when appropriate and need reassurance that hospitals and their emergency departments are safe to visit. Furthermore, emergency physicians and radiologists in particular should be vigilant during times when emergency volumes are low, such as a future surge in coronavirus patients, other pandemics, snow storms, and holidays as the patients who do present for care are more likely to present at later stages and with serious complications.

Abstract
Diverticular disease and diverticulitis are the most common non-cancerous pathology of the colon. It has traditionally been considered a disease of the elderly and associated with cultural and dietary habits. There has been a growing evolution in our understanding and the treatment guidelines for this disease. To provide an updated review of the epidemiology, pathogenesis, classification and highlight changes in the medical and surgical management of diverticulitis. Diverticulitis is increasingly being seen in young patients (< 50 years). Genetic contributions to diverticulitis may be larger than previously thought. Potential similarities and overlap with inflammatory bowel disease and irritable bowel syndrome exist. Computed tomography imaging represents the standard to classify the severity of diverticulitis. Modifications to the traditional Hinchey classification might serve to better delineate mild and intermediate forms as well as better classify chronic presentations of diverticulitis. Non-operative management is primarily based on antibiotics and supportive measures, but antibiotics may be omitted in mild cases. Interval colonoscopy remains advisable after an acute attack, particularly after a complicated form. Acute surgery is needed for the most severe as well as refractory cases, whereas elective resections are individualized and should be considered for chronic, smoldering, or recurrent forms and respective complications (stricture, fistula, etc.) and for patients with factors highly predictive of recurrent attacks. Diverticulitis is no longer a disease of the elderly. Our evolving understanding of diverticulitis as a clinical entity has led into a more nuanced approach in both the medical and surgical management of this common disease. Non-surgical management remains the appropriate treatment for greater than 70% of patients. In individuals with non-relenting, persistent, or recurrent symptoms and those with complicated disease and sequelae, a segmental colectomy remains the most effective surgical treatment in the acute, chronic, or elective-prophylactic setting.

Abstract
Diverticular disease of the colon and small bowel is an important cause of pathology leading to emergency department visits and urgent gastrointestinal surgery. CT is a highly sensitive and specific modality for the diagnosis of acute diverticulitis and its complications as well as for the exclusion of alternate causes of pathology. Ultrasound, MRI and virtual CT colonoscopy have important adjunct roles for screening and workup of complications in specific patient populations. While diverticular disease most commonly involves the descending and sigmoid colon, it can also affect the proximal colon and small bowel. Acute diverticulitis may be categorized as uncomplicated or complicated according to the degree of inflammatory changes and related complications it induces, although some degree of overlap exists in clinical practice. Uncomplicated diverticulitis is classically characterized by localized inflammation surrounding a diverticulum ranging from wall thickening and phlegmonous change to the development of small, localized pericolic abscesses. Complicated forms of disease manifest with larger pericolic and distant abscesses, fistulae to adjacent organs, perforation, and peritonitis. Recurrent episodes of diverticulitis may lead to muscular hypertrophy of the bowel wall and luminal narrowing, potentially leading to bowel obstruction. Several imaging features may help to differentiate diverticulitis from colonic malignancy, however this remains a diagnostic imaging challenge that often requires further evaluation with colonoscopy. In this review, we discuss the pathophysiology and key imaging features of acute diverticulitis and its complications. We explore both common and uncommon presentations of the disease involving the colon and small bowel, acute and chronic manifestations of disease, and pitfalls to recognize when imaging alone may be insufficient to distinguish benign from malignant.

Abstract
BACKGROUND Some patients with uncomplicated diverticulitis have extraluminal air. Our objective was to determine if patients with Hinchey 1a diverticulitis and isolated extraluminal air present more severe episode than patients without extraluminal air. METHODS The present study is a monocentric observational retrospective cohort study. Computed tomographies of patients with diagnosed uncomplicated diverticulitis were retrospectively reviewed from the 01 January 2005 to the 31 December 2009. The presence of extraluminal air was determined. Leukocyte count, CRP value, and length of hospitalization were extracted from the patients' files. The follow-up period was from the time of diagnosis to the 15th of March 2019, the latest. Follow-up was censored for death and sigmoidectomy. Recurrence and emergency sigmoidectomy were documented during the follow-up period. The study was performed according to the STROBE guideline. RESULTS Three hundred and one patients with an episode of Hinchey 1a diverticulitis were included. Extraluminal air was present in 56 patients (18.60%). Leukocyte count (12.4 ± 4.1(G/l) versus 10.7 ± 3.5(G/l), p = 0.05), CRP value (156.9 ± 95.1(mg/l) versus 89.9 ± 74.8(mg/l), p < 0.001), and length of hospital stay (10.9 ± 5.5(days) versus 8.4 ± 3.6(days), p < 0.001) were significantly higher in patients with extraluminal air than in patients without extraluminal air. Seventy-two patients (23.92%) presented a recurrence during the follow-up period. Survival estimates did not differ between patients with or without extraluminal air (p = 0.717). Eleven patients (3.65%) required emergency surgery during the follow-up period. Patients with extraluminal air had shorter emergency surgery-free survival than patients without extraluminal air (p < 0.05). CONCLUSION The presence of extraluminal air in Hinchey 1a diverticulitis indicates a more severe episode, with higher inflammation parameters at admission, longer length of stay, and an increased risk for emergency sigmoidectomy.

Abstract
INTRODUCTION Bowel wall thickening is not an uncommon finding among patient undergoing abdomen CT scan. It may be caused by neoplastic, inflammatory, infectious or ischaemic conditions but also be a normal variant. Although specific radiologic patterns may direct to a precise diagnosis, occasionally misidentification may occur. Thus, in the absence of guidelines, further and not always needed diagnostic procedures (colonoscopy, esophagogastroduodenoscopy or capsule endoscopy) are performed. PATIENTS AND METHODS We conducted a retrospective study on data collected from May 2016 to June 2017. We selected 40 adult patients, admitted in Emergency Department with "abdominal pain" and undergone an abdomen CT scan, in which bowel wall abnormalities were founded. RESULTS 75% patients were found to have a benign condition vs 25% a malignant condition. In the stomach group, 50% were found to have a neoplasm, whilst 33.3% presented an aspecific pattern and 16.7% had an inflammatory disease. In the small bowel cluster, 33.3% patients had an ischaemic disease, 33.3% an aspecific pattern, 22.2% an inflammatory disease and 11.1% was diagnosed with cancer. In the colon group, 36% had an inflammatory disease, 24% a colon cancer, 24% an aspecific pattern and 16% an ischaemic condition. CONCLUSIONS We recommend to perform a further endoscopic procedure to all patients with gastric or colonic wall abnormalities on CT scan, on the basis of growing rate of cancer and IBD. Capsule endoscopy should be taken into account in patients with severe symptoms and after a previous negative endoscopic examination.

Abstract
BACKGROUND/OBJECTIVE A preoperative reliable classification system between clinical and computed tomography (CT) findings to better plan surgery in acute complicated diverticulitis (ACD) is lacking. We studied the inter-observer agreement of CT scan data and their concordance with the preoperative clinical findings and the adherence with the intraoperative status using a new classification of diverticular disease (CDD). METHODS 152 patients operated on for acute complicated diverticulitis (ACD) were retrospectively enrolled. All patients were studied with CT scan within 24 h before surgery and CT images were blinded reanalyzed by 2 couples of radiologists (A/B). Kappa value evaluated the inter-observer agreement between radiologists and the concordance between CDD, preoperative clinical findings and findings at operation. Univariate and multivariate analysis were used to evaluate the predicting values of CT classification and CDD stage at surgery on postoperative outcomes. RESULTS Overall inter-observer agreement for the CDD was high, with a kappa value of 0.905 (95% CI = 0.850-0.960) for observers A and B, while the concordance between radiological and surgical findings was weak (kappa values = 0.213 and 0,248, respectively and 95% CI = 0.106 to 0.319 and 95% CI = 0.142 to 0.355, respectively). When overall morbidity, mortality and the need of a terminal colostomy were considered as main endpoints no concordance was observed between surgical and radiological findings and the CDD (P=NS). CONCLUSIONS The need for a more accurate classification of ACD, able to better stage this emergency, and to provide surgeons with reliable information for the best treatment is advocated.

Abstract
The management of perforated diverticulitis is a challenging aspect of general surgery. The prevalence of colonic diverticular disease has increased over the last decade and will continue to increase as the baby boomers add to the elderly population. Improvements in diagnostic imaging modalities, efforts to maintain intestinal continuity, and percutaneous drainage procedures now result in several alternatives when selecting a management strategy for complicated presentations. Specifically, laparoscopic lavage and resection with primary anastomosis have emerged as options for treatment of Hinchey III and IV diverticulitis in place of diversion in the appropriately selected patient. Percutaneous drainage of Hinchey II diverticulitis in centers equipped with interventional radiology provides another minimally invasive adjunct. The objective of this paper is to provide an update on the current management of perforated diverticulitis, with a focus on the advantages and disadvantages of the surgical options for the treatment of Hinchey III and IV diverticulitis.

[PMID: 29021428 PMCID: PMC5725849 DOI: 10.2169/internalmedicine.7710-16] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2016] [Accepted: 01/20/2017] [Indexed: 01/12/2023] Open
Abstract
Objective The purpose of this study was to investigate whether changes occurred in the clinical features of acute colonic diverticulitis (ACD) over a period of 10 years, to estimate the long-term probability of disease recurrence and to investigate whether it could be treated in an outpatient setting. Methods Between January 1998 and January 2009, 488 ACD patients were diagnosed and treated in Saiseikai Central Hospital, Tokyo. The diagnoses were made by ultrasonography (US) and/or CT. We investigated the time-dependent changes in the characteristics of patients with ACD, and we used the Kaplan-Meier method to estimate the cumulative probability of recurrence, based on information from a questionnaire. Results The percentage of patients who were diagnosed with left-sided ACD significantly increased over time in comparison to those with right-side disease (4% in 1998, 36% in 2009). Patients with left-sided ACD were significantly older and were diagnosed at a more advanced disease stage than those with right-sided ACD. Among the 212 ACD patients who responded to the questionnaire, the cumulative probability of recurrence in 125 patients with no history of ACD at 2.9, 5.9 and 10.1 years was 16.0%, 20.1% and 26.2%, respectively. The probability of recurrence in patients with right-sided and left-sided ACD did not differ to a statistically significant extent. In addition, outpatient treatability in patients with left-sided to right-sided ACD did not differ to a statistically significant extent (66.6% vs. 70.1%). Conclusion The ratio of left-sided to right-sided ACD was found to have increased over the past decade. Left-sided ACD patients were older and their incidence of complications was higher in comparison to right-sided patients; however, the rate of recurrence and outpatient treatability in patients with left-sided and right-sided ACD did not differ to a statistically significant extent.

Abstract
BACKGROUND Inpatient treatment of patients with colon diverticulitis represents a significant financial and clinical burden to the health care system and patients. The aim of this study was to compare patients with diverticulitis in the emergency department (ED), who were discharged to home vs admitted to the hospital. STUDY DESIGN We reviewed all patients evaluated in the ED of a metropolitan health system, with the primary diagnosis of diverticulitis (ICD-9 562.11), from 2010 through 2012. Only patients diagnosed with CT and those with follow-up were included. RESULTS We identified 240 patients; 132 (55%) were women and mean age was 59.1 years (SD 16.1 years). Imaging findings included extraluminal air (21%), pericolic or pelvic abscess (12%), free fluid (16%), and pneumoperitoneum (6%). One hundred forty-four (60%) were admitted to the hospital and 96 (40%) were discharged to home on oral antibiotics. Patients admitted to the hospital were more likely to be older than 65 years (p = 0.0007), have a Charlson comorbidity score ≥ 2 (p = 0.0025), to be on steroids or immunosuppression (p = 0.0019), and have extraluminal air (p < 0.0001) or diverticular abscess (p < 0.0001) on imaging. Median follow-up for all patients was 36.5 months (interquartile range 25.2 to 43 months). Among patients discharged from the ED, 12.5% returned to the ED or were readmitted within 30 days, with only 1 patient (1%) requiring emergency surgery, but not until 20 months later. Patients admitted to the hospital had similar rates of readmission (15%; p = 0.65). CONCLUSIONS Patients diagnosed with uncomplicated diverticulitis in the emergency room can be safely discharged home on oral antibiotics, as long as CT findings are included in the decision-making process. Patients with complicated diverticulitis on CT scan should be admitted to the hospital with surgical consultation.

Abstract
OBJECTIVE Routine CT for patients with acute flank pain has not been shown to improve patient outcomes, and it may unnecessarily expose patients to radiation and increased costs. As preliminary steps toward the development of a guideline for selective CT, we sought to determine the prevalence of clinically important outcomes in patients with acute flank pain and derive preliminary decision rules. METHODS We analyzed data from a randomized trial of CT vs. ultrasonography for patients with acute flank pain from 15 EDs between October 2011 and February 2013. Clinically important outcomes were defined as inpatient admission for ureteral stones and alternative diagnoses. Clinically important stones were defined as stones requiring urologic intervention. We sought to derive highly sensitive decision rules for both outcomes. RESULTS Of 2759 participants, 236 (8.6%) had a clinically important outcome and 143 (5.2%) had a clinically important stone. A CDR including anemia (hemoglobin <13.2g/dl), WBC count >11000/μl, age>42years, and the absence of CVAT had a sensitivity of 97.9% (95% CI 94.8-99.2%) and specificity of 18.7% (95% 17.2-20.2%) for clinically important outcome. A CDR including hydronephrosis, prior history of stone, and WBC count <8300/μl had a sensitivity of 98.6% (95% CI 94.5-99.7%) and specificity of 26.0% (95% 24.2-27.7%) for clinically important stone. CONCLUSIONS We determined the prevalence of clinically important outcomes in patients with acute flank pain, and derived preliminary high sensitivity CDRs that predict them. Validation of CDRs with similar test characteristics would require prospective enrollment of 2100 patients.

Abstract
Data regarding management of colonic diverticulitis in renal transplant recipients (RTRs) are limited. This study aims to identify prevalence, risk factors, and outcomes in RTRs with colonic diverticulosis and diverticulitis. Between January 2004 and December 2013, all patients who underwent kidney transplantation were analyzed. Among all RTSs, patients who had a pretransplant colonoscopic diagnosis of diverticulosis and patients with a proven attack of diverticulitis were included in our analysis. There were 1578 RTRs with a mean age of 50 ± 14 years at the time of transplantation. Of these, 409 patients had colonoscopic evaluation and 174 (43%) were diagnosed with diverticular disease. Fifteen (0.9%) out of 1578 developed a primary attack of diverticulitis. Two patients underwent a Hartmann's procedure due to perforation. Among 13 patients who were initially treated nonoperatively, 4 required surgery due to refractory diverticulitis (n = 2) and recurrence (n = 2). Tobacco use (59% vs 48%, P = 0.02), increased age (58 vs 51 years, P < 0.0001), diabetes (33% vs 35%, P = 0.03), coronary artery disease (38% vs 22%, P = 0.001), and autosomal dominant polycystic kidney disease etiology (P = 0.04) were more common in RTRs with diverticulosis. Majority of RTRs with diverticulitis can be managed nonoperatively. Surgical treatment is warranted in patients with perforated, persistent, and recurrent diverticulitis. A special care and follow-up may be needed in RTRs with autosomal dominant polycystic kidney disease etiology, smoking history, and coronary artery disease due to higher risk of diverticulosis and subsequent potential diverticulitis.

Abstract
The development of colonic diverticula is common in developed countries and complications of colonic diverticulosis are responsible for a remarkable burden of the disease. The natural history and management of complicated and recurrent diverticulitis in young patients are still a matter of debate. Coloenteric fistula is a rare complication of diverticulitis in young adults. In this report, and utilising a case study, we will review the natural history, outcome and management of acute diverticulitis in the young.

Abstract
A 62-year-old female was admitted to the hospital with pain in the lower abdomen and fever since 1 week. A CT scan showed retroperitoneal air around the inferior mesenteric vein and diverticulitis of the sigmoid. We made the diagnosis of intramesocolic diverticular perforation of the sigmoid, a rare phenomenon, and performed an emergency sigmoidectomy.
