[The medical therapy of chronic pancreatitis. Problems, progress and outlook].
The aims of medical therapy in chronic pancreatitis are mainly to relieve the recurrent pain and to correct any malabsorption secondary to digestive insufficiency resulting from deficient exocrine pancreatic function. The treatment of the pain initially involves the use of dietary measures and analgesic drugs. The results of the use of pancreatic extracts and somatostatin reported in the literature are controversial, as are those of coeliac plexus block. Of unquestionable efficacy, at least in the short to medium term, are surgical decompression interventions in patients, with pain refractory to these measures and who present significant dilation of Wirsung's duct at ERCP. Endoscopic decompression constitutes an alternative to surgical decompression. In view of the transitory results of endoscopic decompression, which, in any event, should be implemented only by endoscopists possessing the necessary experience and expertise, the use of this technique may perhaps be targeted at carefully selected patients to be submitted to surgical decompression. As far as maldigestion is concerned, which occurs only when the pancreatic functional deficit reaches 90% or more, replacement therapy with pancreatic extracts must be resorted to. Multi-Unit Dose preparations are to be preferred, consisting in gastro-protected microspheres measuring not more than 2 mm in diameter and containing high doses of lipase, since at least 30,000 I.U. of lipase are required in the post-prandial phase for reasonably satisfactory correction of the steatorrhoea. Should this fail to prove effective, it is good policy to add antisecretory drugs (H2-antagonists, proton-pump inhibitors).
