Roux-en-Y duodenojejunostomy improves gastric emptying in experimental obstruction of the distal duodenum - Fig 5

<p>Sequential imaging with a gamma camera of the gastric emptying of a radiolabelled solid meal during the early postoperative period (4 weeks after surgery): series A (upper panel)–in a dog with a gastrojejunoanastomosis (GA), series B (lower panel)–in a dog with Roux-en-Y duodenojejunoanastomosis (DA), created in either case for an experimental obstruction of the duodenum. It can be inferred that radioactivity is retained within the stomach throughout 3 h in the GA dog, whereas a normal passage of the radiolabelled meal from the stomach to the intestines occurs in the DA dog.
