Case Description

9 month old male anorectal malformation with rectovesical fistula and complete colonic duplication. Underwent colon merging and sagittal posterior anorectoplasty #surgery #pediatricsurgery #Anorectum #colon

Images

19yr old female, found to have #intestinal-TB with #Fistula btw ilium and colon, #Fistula was resected, #Colon was sutured up, 1m of ilium was removed and #end-iliostomy was made so that #Colon and #Peritoneum can heal properly. (Sorry I was not able to take the picture of tuberculous lesion)

Lateral image from a high-pressure distal colostogram in a neonate with an anorectal malformation shows contrast filling the sigmoid colon and rectum (red arrow), a rectourethral fistula (yellow arrow), and contrast in the urinary bladder (red arrowhead). A BB marks the expected location of the anus (yellow arrowhead). Rectourethral fistula is an expected findings in the setting of an imperforate anus. The high-pressure distal colostogram is used to identify the location and extent of the fistula to plan for corrective surgery. If high pressure is not used, the rectourethral fistula may not open. In some patients with Down syndrome, a fistula may not be present.

Image description Coronal postcontrast T1-weighted (image 1) and T2-weighted (image 2) MRI show colonic inflammation (arrow) with a fistulous tract (arrowhead) extending to the dome of the urinary bladder. The bladder wall is focally thickened at the site of fistula insertion.

Teaching point Colovesicular fistulas are an uncommon complication of Crohn disease and result from chronic transmural inflammation. MRI is well suited for delineating fistula anatomy and bladder involvement and can explain urinary symptoms such as recurrent infections or pneumaturia.

85y/o f with cholecysto-colonic fistula. 3 cm gallstone stuck proximal to sigmoid colon. Thickening to surrounding colon.
