Appendicectomy has been performed. Oral contrast has not passed beyond the stomach and there is distension of small bowel loops with fluid consistent with ileus. In the right iliac fossa, medial to the ileocecal junction and directly anterior to the appendicectomy clips, there is a rounded fluid collection containing some antedependent gas with maximal dimensions of 4.5 x 5.7 x 4.5 cm (ML by AP by SI). There is the impression of collapsed bowel surrounding the anterior aspect of the fluid collection. A small volume of free fluid is seen within the pelvis.
