Intestinal malrotation, mesocolic hernia, and Meckel diverticulum - differential diagnosis of abdominal pain in adults: case report and literature review

Intestinal malrotation is a congenital anomaly caused by incomplete rotation or absence of rotation of the primitive intestine along the axis of the upper mesenteric artery during embryonic development. Embryonic development and its anatomical variations were described by Dott in 1923. Intestinal malrotation is a rare condition among adults - prevalent in a mere 0.0001% to 0.19% of the population -, and it may be associated with other anatomical deformities. It can be asymptomatic or manifest with varying intensity, from obstruction to necrosis of intestinal segments. In general, this abnormality is diagnosed in the first year of life; however, symptomsmay appear later in life,making diagnosis in adults difficult on account of non-specific symptoms. In the present study, we report a case of intestinal malrotation associated with chronic non-specific symptoms progressing to mesenteric angina. (AU)

Revascularization of the Superior Mesenteric Artery in an Intestinal Angina / 日本心臓血管外科学会雑誌

A 69-year-old woman suffered from postprandial abdominal pain and hematochezia. Colonoscopy suggested ischemic colitis, and intestinal angina was diagnosed by multirow-detector computed tomography (CT), which showed occlusion of the superior mesenteric artery (SMA). On enhanced CT, there was extensive calcification on the aortic wall and aortic expansion and several mural thrombi in the thoracoabdominal and abdominal aorta, as well as severe stenoses in the bilateral common iliac arteries. A bypass from the right renal artery, which was the only artery without significant stenosis of the major branches of the abdominal artery, to the SMA, was created using a saphenous vein graft. Postoperatively, the postprandial abdominal pain disappeared, and the patient was discharged after a good postoperative course.

A Case Report of Percutaneous Transluminal Angioplasty with Stenting in

Percutaneous transluminal angioplasty(PTA) was first described by Dotter and Jukins in 1964 and subsequently modified by Gruentzig and Hoff in 1974. PTA has proved a safe and effective treatment for focal atherosclerotic disease of the aorta and its major extremity branches. The complications of PTA of the peripheral vessels are less frequent and less serve than those associated with the comparable surgical procedure. Intestinal angina is a clinical syndrome compromising postprandial abdominal pain, nausea, vomiting, diarrhea, weight loss, and eventually fear of eating. The syndrome is thought to be due to visceral ischemia, with stenosis or occlusion of the three visceral arteries being necessary for the syndrome to occur. Although the first report of mesenteric PTA appeared in 1980, the series of PTA with stenting of the visceral arteris reported in the literature have been small or included limited follow-up. We report a case of a intestinal angina due to superior mesenteric arterial stenosis. A 69-year-old male complained of serve postprandial pain, chronic diarrhea for 1 year. PTA with stening in superior mesenteric artery results in recannulation of obstructed artery and relief of symptom.
