LECTURE: Diseases of pancreas. Acute and chronic pancreatitis, its complications. Etiology, pathogenesis, clinic and treatment. • Author – reader R.Ya. Kushnir
The basis of disease of pancreas is degenerative-inflammatory processes which are considered to be acute pancreatitis, the so called autolysis tissue by its own enzymes.
“Starting” factors of origin of cholelithiasis disease • an alcohol and food overloads (fat and irritating products); • traumas of pancreas; • separate infectious diseases (parotitis, mononucleosis) • infection of bilious ways; • in 10–20 % of patients the reason of acute pancreatitis remains unknown (cryptogenic form).
Classification(V All-russian convention of surgeons, 1978) • I. Clinico-anatomy forms: • 1. Arching form. • 2. Fatty pancreatonecrosis. • 3. Hemorrhagic pancreatonecrosis. • II. Prevalence of necrosis: • 1. Local (focus) damage of gland. • 2. Subtotal damage of gland. • 3. Total damage of gland.
Classification • III. Ran across: abortive, progressive. • IV. Periods of disease: • 1. Period of hemodynamic violations and pancreatogenic shock. • 2. Period of functional insufficiency of parenchymatous organs. • 3. Period of degenerative and festering complications.
Clinical passing • Pain, vomiting and phenomena of dynamic intestinal obstruction are considered the most characteristic signs of acute pancreatitis.
Symptoms • The Mondor’s symptom is violet spots on face and trunk. • The Lagermph's symptom is acute cyanosys of person. • The Halsted's symptom is cyanosys of abdominal skin. • The Gray's symptom is cyanosys of lateral walls of abdomen. • The Kullen's symptom is the yellow colouring of skin near a belly-button.
Symptoms • The Korte's symptom is painful resistance as a lumbar bar in a epigastric area on 6–7 cm higher belly-button. • The Voskresynskyy's symptom is absence of pulsation of abdominal aorta in an epigastric area. • The Mayo-Robson's symptom is feeling of pain at pressure by fingers in the left costal-vertebral corner. • The Rozdolskyy's symptom — painfulness at percussion above pancreas. • The Blumberg's symptom — in patients with acute pancreatitis more frequently is low-grade.
Clinical passing of pancreatonecrosis • The I period (hemodynamic violations and pancreatogenic shock) • The II period (insufficiency of parenchymatous organs) • The III period (postnecrosis dystrophic and festering complications)
Variants of clinical passing and complications • Clinical passing of disease can be: • Abortive; • Slowly; • Quickly progressive
Diagnosis program • 1. Anamnesis and physical methods of inspection. • 2. General analysis of blood and urine. • 3. Biochemical blood test (amylase, bilirubin, sugar). • 4. Analysis of urine on diastase. • 5. Sonography.
Diagnosis program • 6. Computer tomography. • 7. Cholecystocholangiography. • 8. Endoscopic retrograde cholangiopancreatography. • 9. Laparoscopy. • 10. Laparocentesis.
Surgical treatment • Cholecystectomy • Transduodenal sphincteroplasty • Omentopancreatopexy. • Abdominisation of pancreas. • Sequestrectomy • Necrectomy • The resection of pancreas • Pancreatectomy
Chronic pancreatitis • Chronic pancreatitis is a progressive inflammation of pancreas with the periodic acutening and remission.
Classification(by O.O. Shalimov) • 1. Chronic fibrous pancreatitis without violation of patency of main pancreatic duct. • 2. Chronic fibrous pancreatitis with violation of patency of main pancreatic duct, dilatated ducts of pancreas and hypertension of pancreatic juice. • 3. Chronic fibrous-degenerative pancreatitis.
Classification • Taking into account clinical passing of chronic pancreatitis, classification of O.O. Shelagurov (1970) can have some changes. Such forms are selected: • 1. Chronic recurrent pancreatitis. • 2. Chronic pain pancreatitis. • 3. Chronic painless (latent) pancreatitis. • 4. Chronic pseudo tumor-like pancreatitis. • 5. Chronic cholecystocholangiopancreatitis (cholangiogenic pancreatitis). • 6. Chronic indurative pancreatitis
Variants of clinical passing • Chronic recurrent pancreatitis. • Chronic pain pancreatitis. • Chronic painless (latent) pancreatitis. • Chronic pseudo tumor-like pancreatitis. • Chronic cholangiogenic pancreatitis. • Chronic indurative pancreatitis
Diagnosis program • 1. Anamnesis and physical methods of inspection. • 2. General analysis of blood. • 3. Biochemical blood test (amylase, bilirubin, sugar). • 4. Analysis of urine on diastase. • 5. Coprograma.
Diagnosis program • 6. Sonography. • 7. Relaxation duodenogram. • 8. Cholecystocholangiography. • 9. Retrograde cholangiopancreatography. • 10. Computer tomography.
Surgical methods of treatment • Operative treatment is done in case of: • 1) calcinosis pancreas with the expressed pain syndrome; • 2) violation of patency of duct of pancreas; • 3) presence of cyst or fistula of resistance to conservative therapy during 2–4 months; • 4) mechanical icterus on soil of tubular stenosis of distal part of general bilious duct;
Surgical methods of treatment • 5) compression and thrombosis of portal vein; • 6) gallstone disease complicated by chronic pancreatitis; • 7) ulcerous disease of stomach and duodenum complicated by secondary pancreatitis; • 8) duodenostasis, complicated by chronic pancreatitis; • 9) impossibility of exception to operation tumors or violations of arterial circulation of blood of pancreas
Cysts of pancreas • Cyst of pancreas is a cavity, filled by liquid (pancreatic juice, exudation, pus), intimately soldered with head, body or tail of organ, is limited by capsule, which has epithelium on internal surface. • Pseudocyst (unreal cyst) is a cavity in pancreas which appears as a result of its destruction, limited by capsule, that does not have epithelium on internal surface.
Classification(by A.N. Bakulev and V.V. Vinogradov, 1952) • I. Innate cysts of pancreas: • 1. Dermoid cysts. • 2. Teratoid cysts. • 3. Innate adenomas. • 4. Fibrocystic degeneration. • 5. Polycystic degeneration.
Classification • II. Inflammatory cysts: • 1. Pseudocysts. • 2. Retention cysts. • III. Traumatic cysts: • 1. As a result of direct damage of gland. • 2. As a result of indirect damage of gland.
Classification • IV. Parasite cysts: • 1. Echinococcosis glands. • 2. Cysticercosis glands. • V. Neoplasty cysts: • 1. Cyst-adenoma. • 2. Cyst-adenocarcinoma. • 3. Cavernous hemangioma. • 4. Cystic epithelioma.
Stages of forming of pseudocyst • I stage (1–1,5 months last) — in the center of inflammatory process the cavity of disintegration, which takes surrounding tissue, appears in an omentum bag. • The II stage (2–3 months) is characterized by the beginning of forming of capsule of pseudocyst. Cyst is magnificent, unformed, acute inflammatory phenomena calms down.
Stages of forming of pseudocyst • The III stage (3–12 months) is completion of forming of capsule of pseudocyst. Last accretes with surrounding organs. • The IV stage (begins an in year from the origin of cyst) is a separated cyst. The cyst is mobile, easily selected from connections with surrounding organs.
Diagnosis program • 1. Anamnesis. • 2. Biochemical blood test (amylase, sugar, bilirubin). • 3. Analysis of urine on diastase. • 4. Coprograma.
Diagnosis program • 5. Sonography. • 6. Contrasting sciagraphy of stomach and duodenum (relaxation duodenography). • 7. Retrograde pancreatocholangiography. • 8. Computer tomography.
Choice of treatment method • On the I stage operation is not used; • On the II stage it is used at suppuration of pseudocyst (external draining of cyst); • On the III — internal draining of cyst is used. • Marsupialization (opening and sewing down of cyst to the parietal peritoneum and skin) is used infrequently;
Choice of treatment method • On the IV stage external and internal draining of cyst and radical operations are applied: • a) enucleation of cysts (executed very rarely); • b) distal resection of pancreas with a cyst.
