Table 3. Factors Increasing the Incidence of Acute Pancreatitis in Inflammatory Bowel Disease
 
Cholelithiasis
Medications
  Thiopurines (azathioprine/6-mercaptopourine)
  Analogues of 5-ASA (mesalamine, sulfasalazine, olsalazine)
  Metronidazole
  Corticosteroids
  Cyclosporine
Duodenal involvement of Crohn’s disease
  Ampullary inflammation
  Duodenopancreatic fistula
Primary sclerosing cholangitis
  Cholelithiasis
  Strictures of common bile duct and of pancreatic ducts
Hypercoagulation

 

Table 4. Management of Acute Pancreatitis in Patients With Inflammatory Bowel Disease
 
Withdrawal of azathioprine/6-mercaptourine and 5-ASA analogues, if there is suspicion for drug-induced AP and the common causes have been excluded
Aggressive intravenous fluid resuscitation
  250 - 500 mL per hour during the first 12 - 24 h
  Lactated Ringer’s should be the preferred isotonic crystalloid fluid; it is contraindicated in hypercalcemia
  Fluid administration should be titrated according to urine output and comorbidities of patient
  Electrolyte replacement
Analgesia
Bowel rest
  In mild AP, oral feeding can be started immediately, if there is not nausea, vomiting and abdominal pain has resolved
  In several AP, enteral nutritional is recommended to prevent infectious complications
Management of complications of AP
  If co-existing active IBD, infliximab and corticosteroids may be used
