The purpose of this poster is to present the normal postoperative anatomy of the abdomen following a classic pancreaticoduodenectomy, as well as the pathological findings that can be identified on the CT scan in the event of complications.

Pancreaticoduodenectomy is a procedure performed most commonly as the treatment of choice in pancreatic adenocarcinoma, which represents the only curative option for this condition, despite all the advances in medical and radiation oncology [1] . However, with the recent developments of both surgical techniques and chemoradiation regimens, patients with limited vascular involvement, which would have previously been rendered inoperable, are now eligible for surgery[2]. Other indications include various periampullary cancers (affecting the papilla of Vater, distal bile duct or duodenum), chronic pancreatitis, neuroendocrine tumors, intraductal...

The classic pancreaticoduodenectomy consists of the resection of the pancreatic head, neck and uncinate process, along with the duodenum, gallbladder, distal bile duct and proximal jejunum, while also removing the gastric antrum and the regional lymph nodes. The resection is followed by the creation of three anastomoses: pancreaticojejunostomy, hepaticojejunostomy, and gastrojejunostomy (Fig. 1)[2]. In some cases, instead of the pancreaticojejunostomy, a pancreaticogastrostomy (Fig. 5)is preferred; however, studies have failed to show advantage of a particular technique, therefore the method of choice is still debatable [4]....

Knowledge of the surgical procedure and anastomoses is of utmost importance to the radiologic interpretation of imaging results. Furthermore, radiologists must be familiarized with the normal postoperative aspects of thepancreaticoduodenectomy and be able to easily recognize the complications that might occur, leading to correct and efficient management of the patient.
