Low side-to-side sigmorectal anastomosis with intestinal staplers

The radiologic appearance of a side-to-side stapled sigmoid to rectal anastomosis is described. Barium which collects in the stump of the sigmoid may give the false appearance of a anastomotic leak and unnecessarily delay colostomy closure. Oblique views and observation in the radiologic suite for emptying of the distal stump will confirm this condition.
