“According to our results, a CT scan triggered by clinical suspicion must be considered the first-line procedure to detect a postoperative leak following primary sleeve gastrectomy or Roux-en-Y gastric bypass.”Continue reading
“Acute bowel ischemia (ABI) can be life threatening with high mortality rate. The radiologist plays a central role in the initial diagnosis and preventing progression to irreversible intestinal ischemic injury or bowel necrosis. The most single imaging findings described in the literature are either non-specific or only present in the late stages of ABI, urging the use of a constellation of features to reach a more confident diagnosis”Continue reading

Conclusion: “Our systematic review found that individual physical examination signs (fever, hemorrhagic bullae, and hypotension) were poorly sensitive for diagnosis of NSTI. CT had superior sensitivity and specificity to plain radiography in diagnosing NSTI, but may not be readily available in all centers, and may not be suitable for unstable patients. Finally, the LRINEC score was poorly sensitive for diagnosis of NSTI, suggesting that a low score is not sufficient to rule out the diagnosis.”
