肠缺血(bowel ischemia,BI)病变是指由于多种原因引起的肠壁血流减少或丧失导致病变段肠管血液供应不足或回流受阻,引起肠道管壁的损伤,造成肠道营养吸收障碍的一种综合症。绝大部分是一种急腹症,急性期死亡率高达 60%～80% 。早期临床表现轻或缺乏特异性,易误、漏诊而错过治疗的最佳时机。至中晚期出现局部肠坏死,...
Acute bowel ischemia represents one of the most dramatic abdominal emergencies and, despite the fact it is more and more frequently observed in clinical practice, its mortality rate remains very high. In recent years Computed Tomography (CT) has proved to be a valid diagnostic tool in the ...
Mimics of acute appendicitis—Alternative diagnoses at sonography, CT, and MRI; specific imaging findings that can help in differential diagnosis Huseyin Toprak, ... Serpil Kurtcan, in Clinical Imaging, 2018 3.11 Mesenteric ischemia In older patients, bowel ischemia is the one of the most common ...
To retrospectively evaluate the diagnostic performance of computed tomography (CT) for detection of small-bowel ischemia in emergency department patients with abdominal pain and to compare the prospective interpretation with a retrospective interpretation by using surgical or pathologic findings as the referen...
We present a case of small bowel ischemia in a 5-year-old with a history of VP shunt for hydrocephalus who presented with symptoms of bowel obstruction. A head computed tomography (CT) was found to have no evidence of hydrocephalus, however, abdomen and pelvis CT was concerning for ischemic...
Generally inferior to a CT scan in acute settings but helpful in partial SBO Cannot be used in bowel ischemia , pregnancy Used as a diagnostic test: Helps decide if surgery is still needed Radiograph by 24 hours after administration: If the contrast agent reaches the colon , SBO is likely...
An overtight- ened ligation is prone to cause local ischemia and necrosis of the intestine and leads to stran- gulated obstruction. Besides, the different methods of clip or clamp are difficult to operate and hard to control the external pressure on the bowel wall. Therefore, a ring ...
Contemporary clinical and diagnostic tools, while advanced, sometimes fall short of conclusively differentiating or detecting severe complications, such as ischemia which may results in gangrenous bowel necrosis.2 Several studies have highlighted adhesions as a predominant cause of SBO. In certain reports...
Computed tomography (CT) is the first-line examination for patients suspected of small bowel obstruction (SBO), but the diagnosis of strangulation or ischemia remains difficult55,56,57,58. Low b-value MRI obtainable in a short acquisition time (less than 60 s) might provide a feasible modal...
(Fig. 2) and 1∗1sigmoidcolon perforationwere found for which jejunal resectionanastomosisand descending endcolostomywere done. There was neither charring of the gutvisceranor signs ofintestinal ischemia. Furtherpostoperative recoverywas uneventful. Patient underwent regular dressings of the laparostomy...
