From: Early postoperative imaging after non-bariatric gastric resection: a primer for radiologists
A 63-year-old male underwent partial gastrectomy with Billroth II reconstruction to relieve a large, non-malignant pyloric ulcer refractory to medical therapy. Early postsurgical CF (A) showed mildly delayed transit of iodinated contrast through the GJS (arrowhead), with fluid level in the gastric remnant. Corresponding CT (B-D) appearances before discharge included dilated remnant stomach (+) with ingested material, surgical staples at the gastric resection site (arrow in B), expected imaging appearance of the duodenal stump (DS, thin arrows in C, D) indicated by a single metallic staple, without surrounding fluid or collections
