RESUMO
The purpose of this study was to compare ERCP and MRCP in terms of invasiveness and cost. A questionnaire regarding patient satisfaction was distributed to 23 ERCP patients and 63 MRCP patients. The practical cost of each examination and total yearly cost for 2002, including medication costs for post-ERCP pancreatitis, were calculated. On a trial basis, the total yearly cost for 2002 was also calculated as a percentage of the cost in 1996. Results of the questionnaire showed that patients tended to favor MRCP over ERCP. In our hospital, the practical costs of MRCP and ERCP were 2063 points and 3964 points, respectively. Medication costs for pancreatitis corresponded to about 3% of the total yearly cost for ERCP. The total yearly costs for both examinations and the medication costs for pancreatitis were about 1,360,000 points. The result of trial calculation with the examination percentage of 1996 was about 1,950,000 points. The results of our study demonstrated that MRCP is a noninvasive examination for patients and that its popularization contributed to a reduction in medical costs. For further popularization of equipment and advanced imaging methods, careful assessment of examination costs is important.
