Abstract

Aim: To determine the pathological features of colonic ischaemia (CI) and their relationship to symptom duration, disease distribution and clinical outcome in a real-world, clinical setting. Method: A retrospective, multicentre chart review was performed in patients diagnosed with CI at Montefiore Medical Center (January 2005 to July 2015), and Yale-New Haven Hospital (January 2005 to June 2010). Patients were included if clinical presentation, colonoscopic findings and colonic pathology were all consistent with CI. Results: Six hundred and sixteen patients with pathologically proven CI were included. Common pathological findings included inflammation (51.1%), ulceration (38.2%), fibrosis (26.0%) and necrosis (20.4%). Infarction and ghost cells were seen in 1.6% and 0.2% of cases, respectively. There was a significant relationship between symptom duration and hyalinization of the lamina propria (P = 0.05) and cryptitis/crypt abscesses (P = 0.01). Patients with isolated right CI (IRCI) were more likely than patients with isolated left CI (ILCI) to exhibit necrosis (P < 0.01), cryptitis/crypt abscess (P < 0.01) and inflammation (P = 0.03). Patients with poor outcomes were more likely to exhibit necrosis (P < 0.01) and capillary fibrin thrombi (P < 0.01) and less likely to exhibit fibrosis (P < 0.01) and epithelial changes (P < 0.01). Conclusion: CI is accompanied by a broad spectrum of pathological findings. The traditional pathognomonic findings of CI are rare and cannot be relied upon to exclude the diagnosis. Patients with IRCI and/or poor outcomes were more likely to have pathological findings of necrosis than patients who had ILCI and/or nonpoor outcomes.
