“…CT has been established as the most valuable imaging technique for identifying the presence, site and cause of GI tract perforation (1, 3, 5-10). Several researchers have reported on the direct and indirect CT findings of bowel perforation, and free extraluminal air has been regarded as a major imaging finding for making the diagnosis of the GI tract perforation (3, 6, 8, 10). CT is highly sensitive for detecting free extraluminal air.…”

“…Classic indirect CT signs pointing toward an ulcer perforation are the presence of an abundant pneumoperitoneum, air located around the round ligament, outlining of the falciform ligament, infiltration of perigastroduodenal fat, and the finding of a gastroduodenal thickening. In a retrospective study (Ghekiere et al 2007a) including 81 digestive perforations, about half of which related to a gastroduodenal perforation, we demonstrated the lack of specificity of indirect signs. The presence of air around the ligamentum teres or visualization of the falciform ligament outlined by some air could be related to a perforation from any other origin when the pneumoperitoneum is abundant.…”

“…USG'nin pnömoperitonu saptamada radyografi kadar etkin olduğunu söyleyen çalışmalar olduğu gibi karın gazı nedeniyle perforasyonun ortaya konmasında yetersiz olduğunu söyleyen çalışmalar da vardır. [12,13] Sonuç olarak USG'de direkt radyografide olduğu gibi BT ile kıyaslandığında düşük tanısal duyarlılığa sahiptir.…”
