In the treatment phase, patients will be randomized in a 2:1 ratio (Viokase® 16 or Placebo). In treatment phase, stool collection period will be performed to allow determination of the CFA% that will serve to assess the efficacy of Viokase® 16 for the correction of steatorrhea. Follow-up procedures will be scheduled 7 to 10 days after discharge. Patients who do not show abnormal findings, adverse events or concomitant medications during the treatment phase will be assessed via follow-up telephone call. Patients who show abnormal findings (physical examination, vital signs, clinical laboratory tests, adverse events, concomitant medications) during the treatment phase will complete a follow-up visit.
