Non-occlusive mesenteric ischemia (NOMI) refers to all types of mesenteric ischemia without any organic blockage of blood vessels. It is usually seen in elderly age group with risk factors of previous myocardial infarction, congestive cardiac failure, aortic insufficiency, renal or liver impairment and post-cardiac surgery. Amongst all the cases of acute mesenteric ischemia, NOMI constitutes 20...

BACKGROUND Computed tomography (CT) as a fast and reliable diagnostic technique is the imaging modality of choice for acute bowel ischemia. However, diagnostic is often difficult mainly due to low attenuation differences between ischemic and perfused segments. PURPOSE To compare the diagnostic efficacy of a new post-processing tool based on frequency selective non-linear blending with that of...

INTRODUCTION Ischemic bowel disease comprises both mesenteric ischemia and colonic ischemia. Mesenteric ischemia can be divided into acute and chronic ischemia. These are two separate entities, each with their specific clinical presentation and diagnostic and therapeutic modalities. However, diagnosis may be difficult due to the vague symptomatology and subtle signs. CASE PRESENTATION We repo...

BACKGROUND Isolated case reports describe bowel ischemia in cocaine users, and the optimal management of these patients remains uncertain. DESIGN Case-control study. SETTING Teaching hospitals. PATIENTS Patients hospitalized for colonic ischemia related to cocaine compared with noncocaine-related ischemic colitis. Cases were identified by using ICD-9 codes and laboratory urine toxicology ...

Early diagnosis of acute mesenteric ischemia (AMI) remains very difficult, partly due to the fact that useful markers of early small bowel ischemia have not yet been identified. Thus, in this study, we aimed to evaluate the levels of serum intracellular enzymes in the tissues and organs in a controlled animal model of mesenteric intestinal ischemia. Forty-eight New Zealand rabbits were divided ...

Purpose. Early recognition of acute mesenteric ischemia (AMI) can be challenging. Extensive bowel necrosis secondary to AMI is associated with high rates of mortality. The aim of this study was to investigate the association between preoperative serum lactate level and the extent of bowel ischemia in patients with AMI. Methods. Data of patients with abdominal pain and elevated serum lactate und...

Purpose: The aims of this pilot study were to reveal the biological characteristics of serum I-FABP and explore its clinical utility as a biomarker in patients with small bowel obstruction (SBO). Methods: Serum I-FABP levels were measured in 37 consecutive patients with SBO between 2007 and 2008. Serum I-FABP levels were compared between ischemia (n = 10) and non-ischemia (n = 27) groups. Serum...

Small bowel transplantation is acknowledged as auto- and allotransplantation. In both instances, there is up to a 4%-10% risk of postoperative ischemia, and as the small bowel is extremely susceptible to ischemia, the timely diagnosis of ischemia is important. The location of the transplant, whether it is buried in the abdominal cavity or in the neck region, increases the challenge, as monitori...

BACKGROUND Hepatic portal venous gas (HPVG) is a rare but potentially lethal condition, especially when it results from intestinal ischemia. Since the literatures regarding the prognostic factors of HPVG are still scarce, we aimed to investigate the risk factor of perioperative mortality in this study. METHODS We analyzed data for patients with intestinal ischemia induced HPVG by chart review...
