Examples of effective or ineffective cases. The green, yellow, orange and magenta lines indicate the small intestine, bladder, sigmoid colon and rectum, respectively. The tandem applicator inserted in the endometrial cavity is displayed as high density. (A) An effective case of oral gastrografin. (B) An ineffective case of oral gastrografin because the uterus/adnexa was not in contact with any part of the small intestine. (C) An ineffective case of oral gastrografin because gastrografin was absent in the small intestine at the area in contact with the uterus/adnexa, although gastrografin was observed in the small intestine at the area where it was not in contact with the uterus or adnexa.
