case_images: Computed tomography scan with oral and injected contrast mediums, axial (a), coronal oblique (b), and sagittal (c) images showing the oral contrast medium unimpeded passage through the grafted retrosternal colon (yellow arrows) until reaching the colon-jejunal anastomosis (orange arrows). At this juncture, a distinctive "bowel within a bowel" configuration was observed, characterized by concentric rings of high- and low-density layers in axial image (white arrow) and a sausage-like appearance in coronal and sagittal images at the juncture (orange arrows).

case_images: At this juncture, a distinctive "bowel within a bowel" configuration was observed, characterized by concentric rings of high- and low-density layers in axial images and a sausage-like appearance in longitudinal images (Figure 1).
case_images: Computed tomography (CT) scan with oral and injected contrast mediums after 12 h of the first CT scan, axial image at the level of the anastomosis (a), axial image at the level of the caecum (b) and sagittal (c) image showing the oral contrast medium unimpeded passage through the grafted retrosternal colon (yellow arrows), the colon-jejunal anastomosis (orange arrow), and reaching the caecum (red arrow). And the disappearance of "bowel within a bowel" configuration that was initially observed in the jejunal colonic anastomosis.

case_images: The previously observed "bowel within a bowel" configuration had disappeared, indicative of a resolution of the obstruction (Figure 2). Additionally, there was a clear progression of the oral contrast medium through the gastrointestinal (GI) tract (Figure 2), signifying restoration of normal bowel function and passage.
