Duodenal lesions following severe acute pancreatitis: review of 10 years' clinical experience.
OBJECTIVE
Acute pancreatitis may result in many local and contiguous organ complications; though the pancreas is in close proximity to the duodenum anatomically, acute pancreatitis causing duodenal lesions is rarely encountered. Our aim is to retrospectively evaluate the clinical features of the duodenal lesions in patients with severe acute pancreatitis.


METHODS
During the past 10 years, 1,637 consecutive patients with acute pancreatitis were admitted to Taipei Veterans General Hospital. Total parenteral nutrition was employed in 251 patients with acute pancreatitis, defined as 'severe acute pancreatitis'. They had all received computed tomography during the hospitalization period, and the computed tomography reports were reviewed to find patients with duodenal involvement induced from pancreatitis. We defined those patients having duodenal wall thickening, extrinsic compression of the duodenum, or other obstructive lesions seen on the computed tomography scan as evident duodenal lesion or duodenal involvement.


RESULTS
Nine cases of evident duodenal lesions following severe acute pancreatitis have been documented over a 10-year period in 1 teaching medical center. The lesions were found by image study or during operation. The most frequently involved site was the second portion of the duodenum. Clinically, 1 unique case developed severe duodenal obstruction requiring surgical correction, and 7 cases recovered after supportive therapy. Of the 9, only 1 case died of multiple organ failure.


CONCLUSIONS
In contrast to the colonic lesions caused by acute pancreatitis with a high morbidity and mortality, total parenteral nutrition yields a good prognosis in patients with evident duodenal lesions following severe acute pancreatitis.
