tell me the cost of the dilation of intestine?It is not neccessary to use all the tables.
 d_icd_diagnoses:  row_id [ number]  icd9_code [ text]  short_title [ text]  long_title [ text] 
SELECT DISTINCT cost.cost FROM cost WHERE cost.event_type = 'procedures_icd' AND cost.event_id IN (SELECT procedures_icd.row_id FROM procedures_icd WHERE procedures_icd.icd9_code = (SELECT d_icd_procedures.icd9_code FROM d_icd_procedures WHERE d_icd_procedures.short_title = 'dilation of intestine'))
