Ascites and secondary bacterial peritonitis associated with small bowel obstruction.

Abstract

Wide albumin gradient (transudative) ascites is usually due to liver disease but may also result from many other disorders, including heart failure, hepatic infiltration by tumor, hepatic vein thrombosis, and veno-occlusive disease. It has not been linked with small bowel obstruction. Narrow albumin gradient (exudative) ascites, usually due to peritoneal carcinoma or inflammation, has been noted in cases of necrotic or perforated bowel, but simple small bowel obstruction has not previously been appreciated as a possible cause for ascites. We report a patient who developed wide albumin gradient ascites and secondary bacterial peritonitis in association with small bowel obstruction. The small bowel obstruction, ascites, and peritonitis resolved with lysis of a single abdominal adhesion.
