Typical clinical manifestations of colonic ischemia include rapid onset of mild abdominal pain and tenderness over the affected bowel, followed by a mild amount of hematochezia within a day of the onset of pain. Most patients have transient, nongangrenous ischemia, but some have severe ischemia.

Ischemia of the intestine may manifest with different clinical features, each one requiring a specific diag­ nosis and treatment approach. Early identification and treatment of acute mesenteric ischemia is cru­ cial to improve prognosis. For that purpose, early angiography followed by surgery or a direct laparo­ tomy in critically ill patients is warranted. Embolec­ tomy and bowel resection for...

BACKGROUND Hepatic portal venous gas associated with non-occlusive mesenteric ischemia is indicative of a serious pathology that leads to bowel necrosis and it has a high mortality rate. Although non-occlusive mesenteric ischemia is acknowledged as a condition that requires early surgical treatment, it has been reported that bowel necrosis and surgical resection of the gangrenous lesion may be ...

The electrical control activity (ECA) of the bowel is the omnipresent slow electrical wave of the intestinal tract. Characterization of small bowel electrical activity during ischemia may be used as a measure of intestinal viability. With the use of an animal model of mesenteric ischemia, serosal electrodes and a digital recording apparatus utilizing autoregressive spectral analysis were used t...

background in contemporary practice, acute mesenteric ischemia (ami) remains a serious cause of morbidity and mortality in abdominal emergencies. objectives we report the measurement of peritoneal fluid potassium and ph on a small series of rats that developed extensive ami following the surgical ligation of superior mesenteric vessels and compare the results with control groups. materials and ...

Intra-aortic balloon pump counterpulsation (IABP) has been shown to prolong life in critically ill cardiac patients. However, complications including distal emboli, balloon rupture, bleeding, limb loss, and bowel ischemia continue to be associated with them. We present a case of a 56-year-old male who suffered bowel ischemia as a result of a malpositioned IABP. While the benefit of such devices...

Idiopathic myointimal hyperplasia of mesenteric veins is a very rare disease occurring in young male patients, with no more than eight cases reported in the world literature. It causes venous ischemia in the sigmoid colon and rectum that clinically resembles inflammatory bowel disease. Pneumatosis intestinalis is also a rare condition usually associated to a wide range of diseases including bow...

Hernias are routine general surgical problems that may present in any age group, regardless of the patient's socioeconomic status. We present a rare case of a complicated ventral hernia leading to short bowel. This is an unusual case and is very rarely reported in the literature. This current case report describes a 54-year-old gentleman who presented to the hospital with a giant strangulated v...

INTRODUCTION The prevailing notion is that ischemia reperfusion injury of the small bowel induces transient changes that resolve within a few days post-occurrence. However, chronic injury has been described following a single ischemia reperfusion in the kidney. We proceeded to ascertain if a similar outcome is also witnessed in the small bowel. MATERIALS AND METHODS ACI rats (n=32) underwent ...

A case of a 63-year-old man with small bowel ischemia six weeks after transplantation surgery is presented. Plain abdominal radiograph obtained several days after ingestion of barium shows the sign of prolonged barium coating indicating severe mucosal damage. Abdominal CT scan demonstrates small bowel wall thickening as well as pockets of peritoneal fluid collections. Most critically, CT allows...
