[PMID: 29103470 DOI: 10.1016/j.ejrad.2017.09.003] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2017] [Revised: 09/04/2017] [Accepted: 09/08/2017] [Indexed: 12/13/2022]
Abstract
PURPOSE The main objective was to evaluate the usefulness of early ultrasonography for determining prognosis of patients with ischemic colitis. MATERIALS AND METHODS We reviewed the histories of patients with diagnosis of ischemic colitis over a period of 11 years. Two hundred twenty nine patients with ischemic colitis were included. Demographic, clinical, laboratory and sonographic findings were retrospectively analyzed. Patients were divided into two groups according to the outcome: mild (those who improved with conservative treatment) or severe (those who died or required surgery), and the findings of each group were compared. In addition, we developed a predictive model of multivariate logistic regression analysis, and then it was validated in a different population of 58 consecutive patients with ischemic colitis. RESULTS The mild ischemic colitis group consisted of 184 patients (age 74,7±8,8years), and the severe group of 45 patients (age 78,6±7,7years). More pancolitis (p=0.005), altered pericolic fat (p=0.032) and free fluid (p=0.013) was observed in the severe ischemic colitis group compared with the mild group. Severe ischemic group had lower wall thickness (p=0.020) and higher resistive index than mild group (p=0.025). Multivariate analysis identified as protective factors to severe ischemic colitis: pain (p=0.026), diarrhea (p=0.034), rectal bleeding (p=0.000), and hypertension (p=0.001). Altered pericolic fat (p=0.008) and pancolitis (p=0.017) were sonographic findings significantly related to severe ischemic colitis. Our model correctly classified 88.4% of the study patients and 89.6% of the population of 58 patients used in validation. CONCLUSIONS Sonographic features with clinical findings can predict the outcome of ischemic colitis. Our predictive model could differentiate properly between patients with mild or severe ischemic colitis.

Abstract
BACKGROUND Ischemic colitis (IC) is a common type of ischemic insult, resulting from decreased arterial blood flow to the colon. This disease can be caused from either atherosclerotic occlusive vascular disease or non-occlusive disease. The aim of this study is to present the diagnostic methodology and management of this severe disease based on current literature. METHODS A literature search has been done including articles referring to modern diagnosis and management of IC. RESULTS IC is usually a transient disease, but it can also cause gangrene of the colon, requiring emergency surgical exploration. Diagnosis is troublesome and is based on imaging examinations, mainly computerized tomography, which in association with colonoscopy can delineate the distribution pattern and severity of disease. CONCLUSION The majority of patients with mild disease have usually complete clinical recovery within a short period. The severe forms of the disease carry high morbidity and mortality rates and prompt surgical intervention is the only way to improve the associated severe prognosis.

Colon ischemia: Right-sided colon involvement has a different presentation, etiology and worse outcome. A large retrospective cohort study in histology proven patients. Best Pract Res Clin Gastroenterol 2017; 31:111-117. [PMID: 28395782 DOI: 10.1016/j.bpg.2016.12.004] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2016] [Revised: 12/04/2016] [Accepted: 12/17/2016] [Indexed: 01/31/2023]
Abstract
BACKGROUND Colon ischemia (CI), is generally considered a non-occlusive mesenteric ischemia disorder that usually runs a benign course, but right-sided involvement (RCI) has been associated with worse outcome. The poor outcome of RCI has been associated with comorbidity, but more recently also with occlusions of the mesenteric arteries. We performed a retrospective analysis of a large cohort of CI-patients to assess differences in presentation, etiology, and comorbidity between right-sided colon ischemia (RCI) and non-right-sided colon ischemia (NRCI), and their relation to outcome. METHODS We performed a retrospective cohort study in two centers from 2000 to 2011 for CI and analyzed clinical presentation, etiology, treatment and outcome. Diagnosis was based on full colonoscopy and/or surgical findings and confirmed by histopathology. RESULTS 239 patients were included (mean age 69, 52% female). RCI was found in 48% and NRCI in 52%. Patients with NRCI presented more often with rectal bleeding (87% vs. 45%; p<0.001). In RCI more nausea (58% vs. 39%; p=0.013), weight loss (56% vs. 19%; p<0.001), paralytic ileus (32% vs. 18%; p=0.018) and peritoneal signs (27% vs. 7%; p<0.001) was observed compared to NRCI. The cause of CI was more often idiopathic in NRCI (46% vs. 26%; p=0.002); an occlusive cause was seen more often in RCI (26.3 vs 2.4%, p<0.0001). RCI patients had longer hospital stay (15 vs. 8 days, p<0.001), need for surgery (61% vs. 34%, p<0.001), and trend toward higher 30-day in-hospital mortality (20% vs. 12%, p=0.084). CONCLUSIONS RCI ischemia has different etiology, presentation, and outcome. The series shows a high proportion of - treatable - vessel occlusion. It reinforces the advice to perform CT angiography in RCI as means to improve its poor outcome.

Abstract
Objectives We aimed to identify the clinical characteristics of ischemic colitis (IC) and to investigate the occurrence of seasonal variation. Methods From January 2008 to December 2014, 368 had IC as the reason for their admission. A total of 364 patients were enrolled in this study. We investigated patient characteristics and seasonal variations in incidence. Results The mean age (±standard deviation) of patients with IC at diagnosis was 66.8 (±16.9) years. Most patients had abdominal pain (341 cases), hematochezia (337 cases), and diarrhea (199 cases) as their chief complaints. The clinical courses of the disease were classified as transient (294 cases), stricture (17 cases), gangrenous (2 cases), and indeterminate types (51 cases). Although IC tended to occur less frequently in winter, the seasonal difference was not significant. Conclusion There is currently no evidence for seasonal variation in hospital admissions for IC.

Abstract
PURPOSE OF REVIEW To provide an update on the epidemiology, pathophysiology, clinical presentation, and management of colonic ischemia. RECENT FINDINGS Formerly regarded as a rare cause of lower gastrointestinal hemorrhage, colonic ischemia is now recognized to be the most common manifestation of intestinal vascular compromise. In contrast to ischemic events in the small intestine wherein thrombotic and embolic events predominate, colonic ischemia typically results from a global reduction in blood flow to the colon and no occlusive lesion(s) are evident. Several risk factors for colonic ischemia have been identified and, together with an appropriate clinical presentation and patient demographics, create a context in which the clinician should have a high level of suspicion for its presence. Imaging with computerized tomography, in particular, may be highly supportive of the diagnosis, which where appropriate can be confirmed by colonoscopy and colonic biopsy. For most patients, management is supportive and noninterventional, and the prognosis for recurrence and survival are excellent. SUMMARY Colonic ischemia is a common cause of lower abdominal pain and hemorrhage among the elderly typically occurring in the aftermath of an event which led to hypoperfusion of the colon. For most affected individuals the ischemia is reversible and clinical course benign.

Abstract
Endoscopy is a keystone in the management of patients with inflammatory bowel disease (IBD). It is the fundamental diagnostic tool for IBD, and can help discern between ulcerative colitis and Crohn’s disease. Endoscopic assessment provides an objective end point in clinical trials, and identifies patients in clinical practice who may benefit from treatment escalation and may assist risk stratification in patients seeking to discontinue therapy. Recent advances in endoscopic assessment of patients with IBD include video capsule endoscopy, and chromoendoscopy. Technological advances enable improved visualization and focused biopsy sampling. Endoscopic resection and close surveillance of dysplastic lesions where feasible is recommended instead of prophylactic colectomy.

Abstract
AIM The study reviews the literature related to ischaemic colitis (IC) as the evidence base to identify factors predicting severity. METHOD A systematic review of the literature was conducted on the predictors of the severity of IC. Severe IC or adverse outcome of IC was defined as a patient requiring surgery or who died. MEDLINE, Embase and Cochrane Library databases were searched from inception to 15 January 2015. Manual searches of reference lists from potentially relevant papers and meetings were also performed. RESULTS In all, 22 studies involving 2823 patients were identified; 19 were case series, two were case-control studies and one was a cohort study. The overall adverse outcome rate was 22.0% (620/2823). The prognostic predictors for surgery or mortality which were most frequently reported included right sided IC, peritonitis, shock or arterial hypotension (< 90 mmHg), male gender, tachycardia and lack of rectal bleeding. Thirteen studies relating to the right colon from which data could be extracted were further analysed. The right colon was involved in 277 cases, with an incidence of adverse outcomes of 48.4% (134/277), while in the non-right colonic involvement group the incidence was significantly lower at 12.1% (142/1175) (P = 0.000). CONCLUSION The incidence of adverse outcome in patients with IC remains high. Male gender, tachycardia, lack of rectal bleeding, peritonitis, shock or arterial hypotension (< 90 mmHg) and right sided IC are predictors of poor prognosis. Right-sided IC, shock or arterial hypotension (< 90 mmHg) and signs of peritonitis may be the most significant predictors of severity.

Abstract
Ischemic colitis (IC) is a common reason of acute lower gastrointestinal bleeding, and it is frequently seen in elderly people. In recent years, both the incidence and prevalence of IC have been rising. Most episodes of IC are transient and self-limited and only a minority of cases are severe. IC often has missed and delayed diagnosis. This review mainly focuses on the progress in the understanding of the diagnosis and therapy of IC.

Abstract
Background/Aims Ischemic colitis includes a wide clinical spectrum ranging from mild to severe forms. This study aimed to determine the factors that are related to the occurrence of severe ischemic colitis. Methods This multicenter study was conducted retrospectively in Korea. The patients were divided into mild and severe groups. This study surveyed clinical characteristics, blood tests, endoscopic findings, and imaging studies. Results In the comparison of comorbidities, the severe group had a higher ratio of chronic kidney disease than the mild group (p=0.001). In the blood test, the severe group had a reduced number of platelets (p=0.018) and a higher C-reactive protein value (p=0.001). The severe group had a higher ratio of involvement of the right colon (p=0.026). The Eastern Cooperative Oncology Group (ECOG) performance status score of the patients showed that the severe group had higher scores than the mild group (p=0.003). A multivariate analysis showed that chronic kidney disease and high ECOG performance status scores were significant risk factors. Conclusions If patients diagnosed with ischemic colitis are also treated for chronic kidney disease or have poor performance status, more attention and early intervention are necessary.

Abstract
Inflammatory bowel disease (IBD) is a chronic inflammatory disease of the gastrointestinal tract and includes both Crohn's disease and ulcerative colitis. Patients with IBD often present with abdominal pain, diarrhea, and rectal bleeding but may also have a wide variety of other symptoms such as weight loss, fever, nausea, vomiting, and possibly obstruction. Given that the presentation of IBD is not specific, the differential diagnosis is broad and encompasses a wide spectrum of diseases, many of which can mimic and/or even coexist with IBD. It is important for physicians to differentiate symptoms due to refractory IBD from symptoms due to IBD mimics when a patient is not responding to standard IBD treatment. Many of the various IBD mimics include infectious etiologies (viral, bacterial, mycobacterial, fungal, protozoal, and helminthic infections), vascular causes, other immune causes including autoimmune etiologies, drug-induced processes, radiation-induced, and other etiologies such as small intestinal bacterial overgrowth, diverticulitis, and bile acid malabsorption. Thoughtful consideration and evaluation of these potential etiologies through patient history and physical examination, as well as appropriate tests, endoscopic evaluation, and cross-sectional imaging is required to evaluate any patient presenting with symptoms consistent with IBD.

Abstract
Ischemic colitis (IC) is the most common vascular disorder of the gastrointestinal tract with a reported incidence of 6.1-44 cases/100,000 person years with confirmatory histopathology. However, the true incidence of IC poses some difficulty, and even vigilant clinicians with patients at high risk often miss the diagnosis, since clinical presentation is non-specific or could have a mild transient nature. Detection of IC results is crucial to plan the correct therapeutic approach and reduce the reported mortality rate (4-12%). Diagnosis of IC is based on a combination of clinical suspicion, radiological, endoscopic and histological findings. Some consider colonoscopy as a diagnostic test of choice; however, preparation is required and it is not without risk, above all in patients who are severely ill. There are two manifestations of vascular colonic insult: ischaemic and reperfusive. The first one occurs above all during ischaemic/non-occlusive mesenteric ischaemia; in this case, the colonic wall appears thinned with dilated lumen and fluid appears in the paracolic space. When reperfusion occurs, the large bowel wall appears thickened and stratified, because of subepithelial oedema and/or haemorrhage, with consequent lumen calibre reduction. Shaggy contour of the involved intestine and misty mesentery are associated with the pericolic fluid. The pericolic fluid results are a crucial finding for IC diagnosis since its evidence suggests the presence of an ongoing damage thus focusing the attention on other pathological aspects which could be otherwise misdiagnosed, such as thinned or thickened colonic wall. Moreover, the pericolic fluid may increase or decrease, depending on the evolution of the ischaemic damage, suggesting the decision of medical or surgical treatment. Radiologists should not forget the hypothesis of IC, being aware that multidetector CT could be sufficient to suggest the diagnosis of IC, allowing for early identification and grading definition, and in a short-term follow-up, discriminating patients who need urgent surgery from patients in whom medical treatment and follow-up can be proposed.

Abstract
Intestinal ischemia is a frequently observed phenomenon. Morbidity and mortality rates are extraordinarily high and did not improve over the past decades. This is in part attributable to limited knowledge on the pathophysiology of intestinal ischemia-reperfusion (IR) in man, the paucity in preventive and/or therapeutic options and the lack of early diagnostic markers for intestinal ischemia. To improve our knowledge and solve clinically important questions regarding intestinal IR, we developed a human experimental intestinal IR model. With this model, we were able to gain insight into the mechanisms that allow the human gut to withstand short periods of IR without the development of severe inflammatory responses. The purpose of this review is to overview the most relevant recent advances in our understanding of the pathophysiology of human intestinal IR, as well as the (potential) future clinical implications.

Abstract
Lower gastrointestinal bleeding (LGIB) is a frequent reason for hospitalization especially in the elderly. Patients with LGIB are frequently admitted to the intensive care unit and may require transfusion of packed red blood cells and other blood products especially in the setting of coagulopathy. Colonoscopy is often performed to localize the source of bleeding and to provide therapeutic measures. LGIB may present as an acute life-threatening event or as a chronic insidious condition manifesting as iron deficiency anemia and positivity for fecal occult blood. This article discusses the presentation, diagnosis, and management of LGIB with a focus on conditions that present with acute blood loss.

Abstract
Colon ischemia (CI) is the most common manifestation of ischemic injury to the gastrointestinal (GI) tract. This usually self-limited disease is being diagnosed more frequently, and the list of known causes is increasing. Local hypoperfusion and reperfusion injury are both thought to contribute to the disease process, which manifests with a wide spectrum of injury including reversible colopathy (subepithelial hemorrhage and edema), transient colitis, chronic colitis, stricture, gangrene, and fulminant universal colitis. The distribution is usually segmental with left-sided disease (e.g., inferior mesenteric artery distribution) being more frequently observed than right-sided involvement (e.g., superior mesenteric artery distribution). Any portion of the colon can be affected, but the anatomic distribution of CI recently has been shown to be associated with outcome. Patients with isolated-right colon ischemia (IRCI) have a different presentation and worse outcomes than other distributions of disease. Although somewhat variable depending on disease location, CI presents with cramping abdominal pains over the segment of colon involved followed by a short course of bloody diarrhea. Diagnosis is usually made clinically and is supported with serologic, radiologic, and colonoscopic findings. Colonoscopy is the most accurate diagnostic study. Most patients respond to conservative supportive therapy although some with more severe disease require antimicrobials and/or surgical intervention.

Abstract
AIM The aim was to prospectively evaluate the positive predictive value of ultrasound in the diagnosis of ischemic colitis, with colonoscopy as the reference standard. METHODS During a 2-year period we included consecutive patients over 50 years of age with sudden abdominal pain and/or rectal bleeding who underwent abdominal sonography in an emergency setting with a thickened segment of colon with a length of more than 10 cm. This clinical-sonographic triad was considered diagnostic for ischemic colitis. A thickened bowel location or color Doppler flow findings on ultrasound examination were evaluated but were not considered to make the diagnosis of ischemic colitis. Basic descriptive statistics were used to characterize the study patients. The positive predictive value was calculated as: number of patients with the definitive diagnosis of ischemic colitis (colonoscopic or follow-up)/number of patients with a sonographic diagnosis of ischemic colitis. RESULTS A total of 48 patients had the clinical-sonographic triad; mean age: 74.3 years (range 54-90 years). The most frequent clinical manifestation was rectal bleeding (83% of the cases) followed by abdominal pain (81%) and diarrhea (45%). A total of 42 cases of ischemic colitis were confirmed by endoscopy (n=35) and biopsy (n=34) or clinical evaluation (n=7). The positive predictive value of the clinical-sonographic diagnosis of ischemic colitis was 87.5%. Thickening of the colon wall was detected on the left side in 35 patients with ischemic colitis, on the right side in 3 and pancolitis was identified in 5 patients. CONCLUSION In an appropriate clinical setting, ultrasound has a high positive predictive value for the diagnosis of ischemic colitis.

Abstract
BACKGROUND & AIMS Patients with ischemia isolated to the right side of the colon (IRCI) frequently have poor outcomes. IRCI and acute mesenteric ischemia (AMI) are caused by reductions in blood supply from the superior mesenteric artery and its branches. We investigated a group of patients with IRCI associated with AMI that developed initially or shortly thereafter, and compared outcomes of patients with IRCI and AMI vs those with only IRCI. METHODS We performed a retrospective study of data collected from 313 consecutive patients with colonic ischemia who were hospitalized at Montefiore Medical Center in New York from 1998 through 2009. Based on colonoscopy, biopsy analyses, and surgery reports, we identified patients with IRCI with concurrent or proximately developing AMI (IRCI+AMI) and those with only IRCI. Demographics, evaluation, disease distribution, and outcome data were compared between groups. RESULTS Of 313 patients with colonic ischemia, 20.8% had IRCI; of these, 84.6% had only IRCI and 15.4% had IRCI+AMI. Chronic obstructive pulmonary disease was found more frequently in patients with IRCI+AMI (40.0%) than in patients with IRCI alone (12.7%; P < .05). At the time of IRCI diagnosis, mean levels of blood urea nitrogen were significantly higher in patients with IRCI+AMI than with IRCI alone (37.9 ± 14.4 mEq/L vs 26.4 ± 18.8 mEq/L; P < .05), as were mean white blood cell counts (20.3 ± 12.1 vs 12.7 ± 6.8 × 10(3)/μL; P < .01). A higher proportion of patients with IRCI+AMI underwent surgery than patients with only IRCI (100.0% vs 43.1%; P = .001), and 30-day mortality was higher among patients with IRCI+AMI (70.0% vs 14.5% for patients with only IRCI; P < .001). CONCLUSIONS Based on an analysis of 313 patients with colonic ischemia, patients with IRCI+AMI have even more severe disease than those with IRCI alone. Chronic obstructive pulmonary disease was observed more frequently in patients with IRCI+AMI. Patients with IRCI+AMI had increased levels of blood urea nitrogen and/or white blood cell counts. Patients with IRCI should undergo vascular imaging analyses immediately to detect AMI; patients without AMI should be monitored closely for its subsequent development.

Abstract
BACKGROUND Acute vascular occlusion within the mesenteric circulation leads to ischemic damage of the corresponding bowel segment, which starts on the mucosal level and progresses transmurally. OBJECTIVES Report on pathogenesis, clinical picture and treatment of various forms of intestinal ischemia. MATERIALS AND METHODS Analysis of the available literature taking into consideration our own experience. RESULTS Frequently, predisposing diseases and risk factors are present (e.g., cardiac diseases, hypercoagulability, status post cardiac surgery, circulatory failure, or administration of vasoconstrictive drugs). Acute small bowel ischemia-caused by either mesenteric embolism, mesenteric artery thrombosis, nonocclusive mesenteric ischemia (NOMI) or mesenteric venous thrombosis-represents an acute emergency. If this condition is suspected clinically, the diagnosis must be established immediately by computed tomography of the abdomen with intravenous administration of contrast medium in order to prevent irreversible damage to the small bowel. Medical treatment is supportive. If possible, occluded vessels may be re-opened either by radiologic intervention or surgically. Irreversibly damaged bowel segments must be surgically removed. Ischemic colitis has a benign course in most cases if limited to reversible mucosal damage. The diagnosis is based mainly on colonoscopy and computed tomography findings, and treatment is symptom oriented. Rarely, severe manifestations with a worse prognosis due to considerable comorbidities occur. In such cases, surgical removal of the ischemic bowel is frequently required. CONCLUSION Even today, acute mesenteric ischemia is associated with a poor prognosis. To improve survival and to reduce long-term morbidity, a rapid and systematic diagnostic workup is mandatory.

Abstract
CONTEXT Large visceral artery occlusion (LVAO) could underlie right-side colon ischemia (RSCI) but is little known. OBJECTIVE To assess patients with RSCI through long-term follow-up, including features and management of LVAO. MAIN OUTCOME MEASURES Mesenteric ischemia and mortality. DESIGN Retrospective observational study in an integrated health care system. RESULTS Of 49 patients (30 women [61.2%]; mean [standard deviation] age, 69.4 [11.9] years), 19 (38.8%) underwent surgery—that is, 5 (83.3%) of 6 who developed RSCI in hospital following surgical procedures and 14 (32.6%) of 43 who had RSCI before hospitalization (p value = 0.03); overall, 5 (10.2%) died. Among 44 survivors with a median (range) follow-up of 5.19 (0.03-14.26) years, 5 (11.4%), including 3 (20.0%) of 15 operated cases, had symptomatic LVAO and underwent angioplasty and stent placement: 2 for abdominal angina that preceded RSCI, 1 for acute mesenteric ischemia 1 week after resection of RSCI, 1 for RSCI 6 weeks after resection of left-side ischemia, and 1 for abdominal angina that began 3 years after spontaneous recovery from RSCI. None had further mesenteric ischemia until death from nonintestinal disease or the end of follow-up (1.6 to 10.2 years later). Kaplan-Meier survival estimates for all 44 survivors at 1, 3, 5, and 10 years were 88.6%, 72.3%, 57.6%, and 25.9%, respectively. Thirty-one patients (70.4%) died during follow-up, 19 (61.3%) of a known cause; the 39 patients not treated for LVAO lacked mesenteric ischemia. CONCLUSION Patients with RSCI may have symptomatic LVAO; therefore, we advise they undergo careful query for symptoms of abdominal angina and routine visceral artery imaging.

Abstract
A 57-year-old female with intrahepatic cholangiocarcinoma underwent hepatic trisegmentectomy and chemoradiation. Her course was complicated by recurrent episodes of radiation-induced gastric outlet obstruction requiring balloon dilations. She presented with right lower quadrant pain after routine upper endoscopy with pyloric dilation. A computed tomography (CT) showed isolated right-sided ischemic colitis with vascular contrast in the mesentery. Repeat CT after conservative management revealed near resolution of the ischemic changes. Perforation at the level of the pylorus is a complication of endoscopic pyloric dilation but vascular injury has never been described.

Abstract
BACKGROUND & AIMS Little is known about progression of ischemic colitis (IC) among unselected patients. We aimed to estimate the incidence, risk factors, and natural history of IC in a population-based cohort in Olmsted County, Minnesota. METHODS We performed a retrospective population-based cohort and nested case-control study of IC. Each IC case was matched to 2 controls from the same population on the basis of sex, age, and closest registration number. Conditional logistic regression, the Kaplan-Meier method, and proportional hazards regression were used to assess comorbidities, estimate survival, and identify characteristics associated with survival, respectively. RESULTS Four hundred forty-five county residents (median age, 71.6 years; 67% female) were diagnosed with IC from 1976 through 2009 and were matched with 890 controls. The age-adjusted and sex-adjusted incidence rates of IC nearly quadrupled from 6.1 cases/100,000 person-years in 1976-1980 to 22.9/100,000 in 2005-2009. The odds for IC were significantly higher among subjects with atherosclerotic diseases; odds ratios ranged from 2.6 for individuals with coronary disease to 7.9 for individuals with peripheral vascular disease. Of IC cases, 59% survived for 5 years (95% confidence interval, 54%-64%), compared with 90% of controls (95% confidence interval, 88%-92%). Age >40 years, male sex, right-sided colon involvement, concomitant small bowel involvement, and chronic obstructive pulmonary disease were all independently associated with mortality (P < .05). CONCLUSIONS The incidence of IC increased during the past 3 decades in a population-based cohort in Minnesota. IC typically presents in older patients with multiple comorbidities and is associated with high in-hospital mortality (11.5%) and rates of surgery (17%).

Abstract
To summarize the frequency of findings on IV contrast, enhanced computer tomography (CT) in 335 patients with pathologically proven ischemic colitis (IC) determine the most frequent locations and patterns of involvement and establish the correlation of these findings with the severity of IC. 231 patients were excluded for not having a concomitant CT or for having underlying comorbidities. 104 cases were analyzed. Scans were evaluated for abnormal wall enhancement (AE), bowel wall thickening (BWT), bowel dilatation (DIL), mesenteric fat stranding (FS), venous engorgement (VE), pericolonic free fluid (FF), and pneumatosis (PN) and portomesenteric venous gas. Segmental versus pancolonic involvement was noted. Severity was determined by histopathology criteria. Data obtained are as follows: female to male incidence, 69 % (70) vs. 31 % (34); average age, 64.5; and positive CT, 102/104 (98.1 %). The most frequent findings include FS (88 %), BWT (88 %), and AE (82 %) regardless of severity of involvement. Statistically significant increased risk ratio and likelihood of severe ischemia for PN, DIL, and FF individually. BWT, DIL, FS, FF, VE, and PN together have a probability for severe IC of 91.8 %. A correlation between fewer findings and milder IC was found (R (2) = 0.6771). The most frequently involved segments: descending (64 %) and sigmoid colon (54 %). Splenic flexure (SF) was infrequently involved (n = 8, 7.84 %). Females had two times higher incidence of IC. The most frequent CT findings in IC are FS, BWT, and AE regardless of the severity. PN is suggestive of severe IC. Segmental involvement is the predominant pattern. The distal colon is more frequently involved. SF contrary to the conventional literature is not disproportionately involved in IC.

Abstract
PURPOSES The long-term clinical course of outpatient-onset ischemic colitis remains unknown. Our aims are to elucidate the in- and out-of-hospital clinical outcomes of ischemic colitis and compare them with those of lower gastrointestinal bleeding (LGIB). METHOD A cohort of 370 outpatients was hospitalized for ischemic colitis (n = 57) or other LGIB (n = 313). All patients had undergone colonoscopy. During hospitalization, the need for transfusion or interventions, further bleeding, mortality, and length of hospital stay were measured. After discharge, long-term recurrence and mortality were analyzed by the Kaplan-Meier method. RESULTS Colonoscopy revealed that 88% of ischemic colitis cases were left sided. Compared with other LGIB, ischemic colitis cases had significantly lower transfusion requirements (p < 0.01), further bleeding (p = 0.02), endoscopic intervention (p < 0.01), and shorter hospital stay (p = 0.03). No significant differences between the groups were noted in the need for surgery, angiographic procedures, or mortality during hospitalization. During a mean follow-up of 22 months, rebleeding was significantly lower (log-rank test; p < 0.01) in ischemic colitis cases (5.3%) than in other LGIB cases (19.4%) after discharge. During the mean follow-up period of 29 months, 1 patient (1.8%) with ischemic colitis and 18 patients (5.8%) with other LGIB died (log-rank test; p = 0.41). CONCLUSIONS Outpatient-onset ischemic colitis patients usually had left-sided colitis, recovered with conservative short-term treatment and had lower transfusion requirements and further bleeding compared with other LGIB patients. After discharge, patients with outpatient-onset ischemic colitis had lower recurrence over the long term than other LGIB patients.

Abstract
OBJECTIVE The aim of our study was to document our 6-year experiences in identifying the clinical characteristics, laboratory findings, risk factors and the outcomes of patients with ischemic colitis (IC) in a community hospital setting. METHODS The medical records of patients who were diagnosed with IC from 2007 to 2013 in two community hospitals were retrospectively reviewed. Their clinical characteristics, laboratory results, radiological, endoscopic and histological evidence, anatomic location of the lesion, comorbidities, concomitant use of drugs, and so on, were collected. RESULTS A total of 118 patients with IC was identified, most were elderly individuals with a female predominance. The most common symptoms were abdominal pain, rectal bleeding and diarrhea. Hypertension, hyperlipidemia, coronary artery disease and diabetes mellitus were the most common comorbidities. Erythema, edema and erosions/ulcerations were the most common endoscopic findings. Left colon was the most affected location of lesion (84.8%), and there was one case of pancolitis. The descending colon was the most common affected segment, while rectum was the least affected segment. Severe IC occurred in 12.7% of the patients. Death within 30 days from the diagnosis of the disease occurred in 4.2%. CONCLUSIONS IC is majorly occurred in elderly with a female predominance. Cardiovascular disease and its associated risk factors are the most common comorbidities. Left colon is the most affected location of the disease and the overall mortality rate was 4.2%. Physicians should make every effort to identify these patients, especially those with high risks.

Abstract
Purpose. This paper aims at evaluating CT findings of occlusive and nonocclusive ischemic colitis (IC), in correlation with the etiology and the different phases of the disease. Materials and Methods. CT examination and clinical history of 32 patients with proven IC were retrospectively reviewed. The CT findings were analyzed according to the different phases of the disease (acute, subacute, and chronic). Results. Among the 32 CT examinations performed in the acute phase, 62.5% did not present signs of occlusion of the superior mesenteric artery (SMA) or inferior mesenteric artery (IMA), whereas IMA occlusion was detected in 37.5% of CT examinations. In the acute phase, the presence of pericolic fluid was found in 100% of patients undergoing progressive resorption from acute to subacute phase if an effective reperfusion occurred; the bowel wall thickening was observed in 28.1% patients in acute phase and in 86.4% patients evaluated in subacute phase. The unthickened colonic wall was found in all conditions where ischemia was not followed by effective reperfusion (71.9% of cases), and it was never found in chronic phase, when the colon appeared irregularly thickened. Conclusion. CT allows determining the morphofunctional alterations associated with the IC discriminating the occlusive forms from the nonocclusive forms. CT, furthermore, allows estimating the timing of ischemic damage.

Abstract
BACKGROUND Acute ischaemic colitis can occur postoperatively, mainly after aortic surgery, or spontaneously. Surgical treatment is debated. Study aim was to describe factors related to ischaemic colitis severity, determine if postoperative and spontaneous ischaemic colitis share similar outcomes, and evaluate results of standardized management. METHODS 191 consecutive cases of ischaemic colitis observed from 1997 to 2012 were retrospectively analyzed: 119 (62%) after surgery and 72 (38%) spontaneous. Colon resection was performed for endoscopic type 2 colitis with multiple organ failure, and for every type 3. Types 1 and 2 without multiple organ failure were managed nonoperatively. RESULTS Seventeen patients (9%) were managed nonoperatively, without mortality. Mortality rate after resection was 48% (84/174), within 9 days (range, 0-152). Multivariate analysis found 2 independent factors associated with postoperative death: age≥75 years and multiple organ failure. The context in which ischaemic colitis occurred was not a risk factor for mortality. Mortality rates were 51% for final type 3 (66% with multiple organ failure, 17% without), 53% for final type 2 with multiple organ failure, and 0% for type 1 or type 2 without multiple organ failure. CONCLUSION An aggressive surgical approach in patients with ischaemic colitis seems justified in patients with multiple organ failure and findings of severe form of ischaemia at endoscopy.

Abstract
PURPOSE Surgery for ischemic colitis is associated with high perioperative morbidity and mortality, but the risk factors for mortality and major surgical complications are unclear. METHODS In this retrospective single institution cohort study of all patients undergoing colorectal surgery for histologically proven ischemic colitis between 2004 and 2010, we evaluated surgical outcomes and risk factors for in-hospital mortality and major surgical complications. RESULTS For the 100 patients included in the study, in-hospital mortality was 54 %; major surgical complications, defined as anastomotic leakage or rectal stump and stoma complications, occurred in 16 %. In the multivariable analysis, hospital death was more likely in patients with right-sided (odds ratio [OR] 3.8; 95 % confidence interval [CI] 1.2, 12; P = 0.022) or pan-colonic ischemia (OR 11; 95 % CI 2.8, 39; P < 0.001), both relative to left-sided ischemia. Decreased preoperative pH level (OR 2.5 per 0.1 decrease; 95 % CI 1.5, 4.1; P < 0.001) and prior cardiac or aortic surgery (OR 2.4; 95 % CI 0.82, 6.8; P = 0.109) were further important risk factors for in-hospital mortality. Major postoperative surgical complications were more likely in patients with ischemic alterations at the resection margin of the histological specimen (OR 3.7; 95 % CI 1.2, 11; P = 0.022). CONCLUSIONS Colonic resection for ischemic colitis is associated with high in-hospital mortality, especially in patients with right-sided or pan-colonic ischemia. In patients developing acidosis, early laparotomy is essential. Since resection margins' affection seems to be underestimated upon surgery, resections should be performed wide enough within healthy tissue.

Abstract
Ischemia is a common type of gastrointestinal injury that can be clinically misdiagnosed due to its often mild and transient clinical presentation as well as a tendency to masquerade as other disorders. A wide range of etiologies can contribute to the development of ischemia. These include hypovolemic states, systemic diseases such as vasculitis and hypercoagulable states, mechanical obstruction, therapeutic drug effects, infection, and a host of other diseases. An accurate diagnosis of ischemia relies on a strong clinical suspicion in combination with endoscopic and pathologic findings. Most cases show histologic features that are diagnostic of ischemia, but do not point to a specific differential diagnosis, whereas the cause of ischemia can be recognized or suspected based on careful review of vascular changes in others. This review is focused on providing an overview of ischemic enterocolitis and its differential diagnosis.

Abstract
Background. CT angiogram is frequently obtained after diagnosis of ischemic colitis (IC). Aims. To investigate the vascular findings of CT angiogram as compared to contrast-enhanced CT scan and whether this modality changes the management or prognosis of IC. Methods. We conducted a retrospective analysis of patients with IC from 2007 to 2013. Results. CT angiogram was performed in 34 patients (28.81%), whereas contrast-enhanced CT scan was performed in 54 patients (45.76%). In CT angiogram group, 8 patients (23.5%) had atherosclerotic changes. Stenosis was found in 12 patients (35.3%) (9: celiac trunk, 3: SMA). Among this group, one patient underwent colectomy and another underwent angioplasty of the celiac trunk who died within 30 days. Among contrast-enhanced CT scan group, 5 patients (9.3%) had atherosclerotic changes. Stenosis was found in 5 patients (9.3%) (3: celiac trunk, 1: SMA, and 1: IMA). Among this group, 3 patients had colectomy and one died within 30 days. There was no statistical difference between both groups in all vascular findings except the stenosis which was higher in CT angiogram group (P = 0.0025). Neither the need for surgery nor all-cause mortality was different between both groups. Conclusion. CT angiogram did not provide any useful findings that altered the management or the prognosis of IC.

Abstract
Ischemic colitis (IC) is the most common type of intestinal ischemia, with a vast clinical spectrum of injury ranging from mild and transient ischemia to acute fulminant colitis. The pattern of injury is usually segmental, but it is mainly dictated by individual anatomy, duration of ischemia, and degree of re-perfusion injury. Analysis of clinical presentation, early endoscopic evaluation, and biopsy are all essential for prevention of misdiagnosis. We present a unique case of IC with mass-like features on regular imaging, emphasizing the importance of endoscopy and biopsy for accurate diagnosis.

Abstract
ObjectivesCompared with all other patterns, isolated right colon ischemia has been found to be more associated with coronary artery disease and a poor prognosis. However, there has been no research on comparing isolated left side ischemic colitis (ILIC) and non-ILIC with vascular assessment. The aim of the present study was to evaluate the clinical and laboratory findings between these two different forms of ischemic colitis (IC). MethodsWe retrospectively investigated differences in clinical features, course, and mesenteric vascular (superior mesenteric artery, SMA; inferior mesenteric artery, IMA) findings between ILIC and non-ILIC patients who were hospitalized at Kosin University Gospel Hospital from 2004 to 2010. ResultsOur study population comprised 221 patients, all of whom met our entry criteria of biopsy-proven or -compatible IC. Of the 221 patients, 46 (20.8%) had non-ILIC. Congestive heart failure and hypercholesterolemia were more frequently observed in the non-ILIC group (P = 0.003 and P = 0.020, respectively). SMA atherosclerosis and SMA stenosis were more frequently observed in the non-ILIC group (P = 0.006 and P = 0.001, respectively). Recovery periods were longer in the non-ILIC group (P = 0.039), and mortality was lower in the ILIC group (6.9% vs. 17.3%, P = 0.026). ConclusionsILIC has favorable outcomes compared with non-ILIC. Furthermore, non-ILIC showed a close relationship with SMA atherosclerosis and SMA stenosis, which should be investigated carefully in the clinical field.

Abstract
AIM: To study the prognosis (recurrence and mortality) of patients with ischemic colitis (IC).
METHODS: This study was conducted in four Spanish hospitals, participants in the Ischemic Colitis in Spain study We analyzed prospectively 135 consecutive patients who met criteria for definitive or probable IC according to Brandt criteria, and follow up these patients during the next five years, retrospectively. Long-term results (recurrence and mortality) were evaluated retrospectively after a median interval of 62 mo (range 54-75 mo).
RESULTS: Estimated IC recurrence rates were 2.9%, 5.1%, 8.1% and 9.7% at years 1, 2, 3 and 5 years, respectively. Five-year survival was 69% (93 of 135) and 24% (10 of 42 patients) died for causes related to the IC. Among these 10 patients, 8 died in their first episode at hospital (4 had gangrenous colitis and 4 fulminant colitis) and 2 due to recurrence.
CONCLUSION: The five-year recurrence rate of IC was low. On the other hand, mortality during follow-up was high and was not associated with ischemic colitis.

Abstract
Gastro-Intestinal Vascular Emergencies include all digestive ischaemic injuries related to acute or chronic vascular and/or haemodynamic diseases. Gastro-intestinal ischaemic injuries can be occlusive or non-occlusive, arterial or venous, localized or generalized, superficial or transmural and share the risks of infarction, organ failure and death. The diagnosis must be suspected, at the initial presentation of any sudden, continuous and unusual abdominal pain, contrasting with normal physical examination. Risk factors are often unknown at presentation and no biomarker is currently available. The diagnosis is confirmed by abdominal computed tomography angiography identifying intestinal ischaemic injury, either with vascular occlusion or in a context of low flow. Recent knowledge in the pathophysiology of acute mesenteric ischaemia, clinical experience and existing recommendations have generated a multimodal and multidisciplinary management strategy. Based on the gastro-intestinal viability around a simple algorithm, and coordinated by gastroenterologists, the dual aim is to avoid large intestinal resections and death.

Abstract
Ischemic colitis is a common cause of hospital admissions; however it is frequently confused intellectually with mesenteric ischemia and often misdiagnosed as infectious diarrhea or Clostridium difficile colitis. Ischemic colitis is caused by non-occlusive insult to the small vessels supplying the colon without a clear precipitating factor. It is more common in females and in patients above 60 years of age. The classic presentation includes sudden onset of lower abdominal pain followed by the urge to defecate and bloody diarrhea. Focal right-sided ischemic colitis has more pain and a worse prognosis. Choosing the correct diagnostic studies is challenging and requires proficient knowledge of the disease. Management is usually conservative, however around 10-20% of the patients will require surgery. Acute ischemic colitis usually resolves; nevertheless some patients may develop chronic segmental colitis or a stricture. One ischemic colitis caveat is that it may be the first sign of undiagnosed cardiac disease. A firm grasp on this common yet little discussed condition is valuable to a gastrointestinal consultant and hospitalist alike.

Abstract
Mucins--large, highly glycosylated proteins--are important for the luminal protection of the gastrointestinal tract. Enterocytes have their apical surface covered by transmembrane mucins and goblet cells produce the secreted gel-forming mucins that form mucus. The small intestine has a single unattached mucus layer, which in cystic fibrosis becomes attached, accounting for the intestinal manifestations of this disease. The stomach and colon have two layers of mucus; the inner layer is attached and the outer layer is less dense and unattached. In the colon, the outer mucus layer is the habitat for commensal bacteria. The inner mucus layer is impervious to bacteria and is renewed every hour by surface goblet cells. The crypt goblet cells have the ability to restitute the mucus layer by secretion, for example after an ischaemic challenge. Proteases of certain parasites and some bacteria can cleave mucins and dissolve the mucus as part of their pathogenicity. The inner mucus layer can, however, also become penetrable to bacteria by several other mechanisms, including aberrations in the immune system. When bacteria reach the epithelial surface, the immune system is activated and inflammation is triggered. This mechanism might occur in some types of ulcerative colitis.

Abstract
In recent years, the importance of the mucus layer in the colon has become increasingly clear. Disturbance of the mucus layer has been implicated in a variety of intestinal diseases. We have recently investigated the importance of the mucus layer in colon ischemia-reperfusion (IR). Using a newly developed human and rat colon IR model, we showed that colon ischemia leads to mucus barrier breakdown. This allowed intraluminal bacteria to interact with the colonic epithelium, which was associated with an inflammatory response. Intriguingly, we found goblet cells to respond immediately by expelling their mucin granules into the gut lumen, which flushed bacteria from the colonic crypts and resulted in rapid restoration of the mucus layer during reperfusion. Our study might explain why ischemic colitis tends to have favorable outcomes and can often be treated conservatively.

Abstract
INTRODUCTION Our objective was to review our 10-year experience of surgical resection for acute ischemic colitis (IC) and to assess the predictive value of previously reported risk-stratification methods. METHODS We retrospectively reviewed all adult patients at our institution undergoing colectomy for acute IC between 2000 and 2009. Descriptive statistics were calculated. Long-term survival was assessed using Kaplan-Meier methods and in-hospital mortality using multivariate logistic regression. Patients were risk-stratified based on previously reported methods, and discriminatory accuracy of predicting in-hospital mortality was evaluated by the area under the curve (AUC) of the receiver operating characteristic (ROC) curve. RESULTS A total of 115 patients were included for analysis, of which 37 % (n = 43) died in-hospital. The median survival was 4.9 months for all patients and 43.6 months for patients surviving to discharge. Seventeen patients subsequently underwent end-ostomy reversal at our institution, with in-hospital mortality of 18 % (n = 3) and ICU admission for 35 % (n = 6). The discriminatory accuracy of risk stratification in predicting in-hospital mortality based on ROC AUC was 0.75. CONCLUSION Acute IC continues to remain a very deadly disease. Patients who survive the initial acute IC insult can achieve long-term survival; however, we experienced high rates of death and complications following elective end-ostomy reversal. Risk stratification provides reasonable accuracy in predicting postoperative mortality.

Abstract
Ischemic colitis (IC) is a rare condition. As ischemia is often transient and clinical symptoms are reversible, its exact incidence is unknown. In current clinical practice, two types of IC are described according to the severity: severe IC, with transmural colonic ischemia and/or multi-organ failure (MOF), and mild IC, without MOF and spontaneous favourable evolution in most cases. Two clinical contexts are encountered: spontaneous IC (SIC) and postoperative IC (POIC), mainly after aortic surgery. As there is no specific clinico-biologic symptom of IC, emergent CT-scan and rectosigmoidoscopy are required for diagnosis confirmation, surgical decision and prognosis analysis. IC surgical treatment is not consensual but can be standardized according to organ function and the degree of ischemia: surgical treatment in case of colonic necrosis with deep ischemia and/or MOF; observation for superficial ischemia without organ dysfunction; systematic medical care. Surgery is required in 20% of cases, and consists in extended colectomy without continuity restoration and prophylactic cholecystectomy. Continuity restoration is feasible in one third of survivors, who are exposed to a high risk of severe cardiovascular events.

Abstract
AIM The study reviews the literature related to ischaemic colitis (IC) to establish an evidence base for its management and to identify factors predicting severity and mortality. METHOD A systematic review of the English language literature was conducted according to recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. MEDLINE, Embase and Cochrane Library databases were searched using the keyword search 'ischaemic colitis OR colon ischaemia OR colonic ischaemia OR management ischaemic colitis'. IC is often misdiagnosed so only studies where the diagnosis was supported by histopathology in every case were included. Critical appraisal was performed of included studies using predefined quality assessment checklists and narrative data synthesis. RESULTS In all, 2610 publications were identified. Of these, eight retrospective case series and three case controlled studies describing 1049 patients were included. Medical management was used in 80.3% patients of whom 6.2% died. Surgery was required in 19.6% of whom 39.3% died. The overall mortality of IC was 12.7%. Lack of rectal bleeding, peritonism and renal dysfunction were commonly quoted predictors of severity; however, right sided IC appeared to be the most significant predictor of outcome. CONCLUSION Most patients with IC can be managed conservatively. Right sided IC may be the most significant predictor of severity.
