Exocrine pancreatic function following pancreatectomy.

Pancreatic exocrine insufficiency can follow major pancreatic resection and result in the malabsorption of fat, causing symptoms of steatorrhea, abdominal pain and weight loss. The extent of malabsorption will depend on the original disease process and the type and extent of surgical resection. The steatorrhea can be severe and difficult to control, and patients may require high doses of pancreatic enzyme supplements. There have been few studies that have looked at the treatment of steatorrhea postpancreatectomy, and very few randomized studies. Results of the latter have demonstrated that after treatment with oral pancreatic supplements over a third of postpancreatectomy patients still have significant levels of steatorrhea. These results show that even using the best available agents the complete elimination of steatorrhea following major pancreatic resection is not possible at the present time. This indicates a need for further effective therapies.
