Abstract

The role of several imaging techniques in patients submitted to pancreatic surgery with special emphasis to single-slice helical computed tomography (CT) and multidetector-row CT (MDCT) was reviewed. Several surgical options may be performed such as Whipple procedure, distal pancreatectomy, central pancreatectomy, and total pancreatectomy. Ultrasound examination may be used to detect peritoneal fluid in the early post-operative period as well as lesion recurrence in long-term follow-up. Radiological gastrointestinal studies has a major role in evaluation of intestinal functionality. In spite of the advent of other imaging modalities, CT is the most effective after pancreatic surgery. On post-operative CT, the most common findings were small fluid peritoneal or pancreatic collections, stranding of the mesenteric fat with perivascular cuffing, reactive adenopathy and pneumobilia. In addition, CT may demonstrate early (leakage of anastomosis, pancreatico-jejunal fistula, haemorrage, acute pancreatitis of the remnant pancreas, peritonitis), and late (chronic fistula, abscess, aneurysms, anastomotic bilio-digestive stenosis, perianastomotic ulcers, biloma, and intra-abdominal bleeding) surgical complications. In the follow-up evaluation, CT may show tumor recurrence, liver and lymph nodes metastasis. Magnetic resonance may be used as alternative imaging modality to CT, when renal insufficiency or contrast sensitivity prevents the use of iodinated i.v. contrast material or when the biliary tree study is primarily requested. The knowledge of the type of surgical procedures, the proper identification of the anastomoses as well as the normal post-operative imaging appearances are essential for an accurate detection of the complications and recurrent disease.
