Operations that remove mechanical obstacles to the outflow of bile and pancreatic juice help to reduce duodenal hypertension or normalize pressure in the duodenum. In functional duodenal hypertension, papillosphincterotomy and choledochoduodenostomy are not contraindicated.</p>chronic calculous cholecystitiscomplicationsduodenal pressureхронический калькулезный холециститосложнениядуоденальное давление
