title: Patterns of morbidity and resource consumption associated with laparoscopic cholecystectomy in a VA medical center.
abstract: BACKGROUND
  The generally low incidence of morbidity and reduced rate of health care resource consumption commonly associated with laparoscopic cholecystectomy (LC) have been established from studies of patient populations which are distinct from that served by the Department of Veterans Affairs (VA) health care system. We sought to assess the outcomes of this procedure when performed on VA beneficiaries.
  
  
  METHODS
  Demographic and perioperative data for all patients undergoing attempted LC in our facility were recorded in a prospective database beginning 1 January 1993. The information in this registry was analyzed to determine the demographics of the treated population, the spectrum of biliary tract disease encountered, and patterns of morbidity and resource consumption.
  
  
  RESULTS
  LC was attempted in 141 cases. Median patient age was 62 years. The indication for surgery was either acute cholecystitis or biliary pancreatitis in 63 cases (45%). Thirteen patients (9%) developed major complications. These patients were significantly older (mean age 68 vs 59 years) than patients whose course was uncomplicated. Twenty-seven cases (19%) required conversion to an open procedure, most commonly for acute cholecystitis. Progressive cholecystitis was associated with a conversion rate of 64%. Both conversion and the development of a major complication produced significant increases in length of stay.
  
  
  CONCLUSIONS
  The population undergoing attempted LC in the VA system is characterized by relatively advanced age and high incidences of comorbid illness and complicated biliary tract disease. These attributes increase the frequency of major morbidity and of conversion to open cholecystectomy, which in turn increase resource consumption. Comparisons between the outcomes of attempted LC in VA centers and "benchmark" results obtained in other settings should be controlled for these factors.
