Standard and volume T2 acquisitions after introduction of 150 ml of sterile ultrasound gel per anally.
Gel is seen to enter a small posterior outpouching at the level of the anastomosis, with linear low signal scar tissue extending from this structure/focus to the presacral fascia. No free fluid in this region. Low signal well-defined wall around periphery of the structure/focus.
Findings suggest no ongoing leak, but rather a small diverticulum.
