[Acute hemorrhagic pancreatitis--extended abdominal drainage and perirenal drainage links].

Acute haemorrhagic pancreatitis, when mainly situated in the body and tail of the pancreas, may be associated with abscess formation in the left perirenal region through the radix mesosoli transversi. Next to the extensive drainage of the abdomen and pancreas, we advise supplementary primary left perirenal-retroperitoneal drainage, considering how difficult it can be to loalize a secondary postoperative pancreatic abscess, especially when a computer-assisted tomography (CAT) is unavailable. In those cases in which the transverse colon had suffered circulatory damage from the acute pancreatitis, good results have been obtained with temporary coecostomy.
