CHRONIC PANCREATITIS COURSE OF DISEASE Prospective study over 20 years N= 254; chronic pancreatitis (163 alcoholic CP, with calcifications in 145) Follow-up 10,4 ys. (median) In 85% of pts. with calcifications continued improvement after 4,5 ys. (median) In 47% of 163 pts. with alcoholic CP surgery necessary 50-60% of pts. with CP develop complications which require endoscopic or surgical intervention Ammann, Gastroenterology 1984 Ammann, Intern Med 2001
CHRONIC PANCREATITIS PAIN Local inflammation of pancreatic tissue with expression of neuropeptides (e.g. substance P) Elevation of pressure in pancreatic duct by stricture Pancreatic compartment syndrome Local compression by pseudocysts Extrapancreatic reasons: Metereorism (steatorrhea) Peptic ulcer Di Sebastiano et al., Gut 2003
CHRONIC PANCREATITIS COMPLICATIONS Pancreatic duct strictures Pancreatic stones Choledochal duct strictures Pseudocysts Inflammatory swelling of pancreatic head Duodenal or colonic stenoses Elevated pressure of portal vein GI- bleeding Exo- und endocrineous insufficiency Cancer + Symptoms = Endoscopic therapy
CHRONIC PANCREATITIS THERAPY - GOALS - 1. Analgesia 2. Therapy of exocrine insufficiency 3. Therapy of endocrine insufficiency Lankisch, Internist 2005
CHRONIC PANCREATITIS MANAGEMENT COMPLICATIONS PAIN MALDIGESTION DIABETES Interventional endoscopy Surgery Alcohol abstinence Enzymes / Diet Spasmolytics Analgetics (NSAID etc.) Surgery Enzymes Diet Insulin
CHRONIC PANCREATITIS PAIN MANAGEMENT Conservative Interventional endoscopy Surgery
CHRONIC PANCREATITIS PAIN CONSERVATIVE TREATMENT - First: exclusion of treatable complications Strict abstinence from alcohol Analgetics (NSAID, non opioid) Celiac block (CT- or EUS- guided) Drug addiction must be avoided
CHRONIC PANCREATITIS ENDOSCOPIC THERAPY - GUIDELINES Concerning the endoscopic therapy of chronic pancreatitis only few randomized controlled prospective trials are available in international literature No long-term results exist regarding the outcome of endotherapy Recommendations concerning therapy of strictures of the pancreatic or choledochal duct and pseudocysts are based on expert opinions and uncontrolled trials DGVS-Leitlinien, Z Gastroenterol 1998

CHRONIC PANCREATITIS SURGERY Severe chronic pancreatitis of head With duodenal stricture With extensive calcifications Multiple strictures of pancreatic duct / multiple stones Failure of conservative and interventional endoscopic therapy (regarding pain,, large pseudocysts,, inner fistulas, bleeding pseudoaneurysm) Suspected cancer Pankreas-Ca DGVS-Leitlinien, Z Gastroenterol 1998 Lankisch, Internist 2005
CONCLUSION More than half of all patients with CP require interventional endoscopic therapy or surgery because of complications Conservative treatment is fundamental but must not lead to drug addiction Endoscopic therapy reduces pain caused by strictures and pseudocysts Surgery is indicated if conventional and endoscopic therapy fails
