title: [Comparative study of direct cost between open and laparoscopic cholecystectomy].
abstract: OBJECTIVE
  to compare the direct cost of open cholecystectomy (OCL) with laparoscopic cholecystectomy (LCL), using a microcosting approach.
  
  
  METHODS
  in patients who underwent cholecystectomy (C) in the Hospital General de Mexico, we collected patient age and sex, time in the operative room (OR), anesthesia and surgical procedure; health personal (HP) involved; materials (M) and medications consumed; medical instruments (MI) and medical equipment (ME) used.
  
  
  RESULTS
  there were 355 patients operated by C, were 248 included, 94 with CAB and 74 with CLP. CAB surgical time was longer than CLP (102 versus 82, p<0.00.1); CLP had a higher use of materials intraoperative ($5 329 versus $1 403, p<0.001). There are no differences in: cost for HP, MI and ME. The total direct cost was $7238 (US$615) for CAB and $12 507 (US$1 063) for CLP (p <0.001) at 11.76 Mexican pesos per dollar.
  
  
  CONCLUSIONS
  the difference in costs between OCL and LCL is primarily explained by the cost of lab exams which represent 79% of the M cost for CLP.
