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(More)
Klippel-Trenaunay syndrome (KTS) is a rare congenital syndrome of vascular malformations and soft tissue and bone hypertrophy. Vascular malformations can affect multiple organ systems. Involvement of the gastrointestinal (GI) tract is uncommon in KTS, but it can be a source of life-threatening bleeding. We report a case of a 32-year-old male with a known(More)
True metastatic involvement of the colon is rare. Colonic metastases occur most commonly secondary to peritoneal metastases from intra-abdominal malignancies. Breast cancer is the most common malignancy that metastasizes hematogenously to the colon. Colonic metastatic disease mimics primary colonic tumors in its presentation. Colonic metastatic involvement(More)
BACKGROUND/AIMS Recurrence of ischemic colitis (IC) has not been studied extensively. The aim of this study was to investigate the characteristics of recurrent IC in the community setting and to identify any risk factors. METHODS We conducted a retrospective study in two community hospitals. Medical records of patients with IC from January 2007 to January(More)
Ischemic colitis is the consequence of a sudden reduction in colonic blood supply, which in turn results in an ischemic injury. The incidence of ischemic colitis ranges from 4.5 to 44 cases/100 000 person-year. It occurs more frequently in the elderly, in those with a mean age of early seventies, and is more common in women. Its prevalence increases with(More)
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(More)
