title: Acalculous gallbladder disease: the outcomes of treatment by laparoscopic cholecystectomy.
abstract: BACKGROUND
  The treatment of symptomatic patients with the presence of gallstones is well established, with laparoscopic cholecystectomy being the treatment of choice for symptomatic cholelithiasis. The results of surgery in symptomatic patients without gallstones are highly variable. These patients are often referred to as having acalculous gallbladder disease and represent between 5% and 30% of laparoscopic cholecystectomies performed annually. We retrospectively reviewed the outcomes of patients who underwent laparoscopic cholecystectomy for acalculous gallbladder disease in our institution.
  
  
  METHODS
  We retrospectively analysed the period from February 2005 to January 2006 where 20 laparoscopic cholecystectomies had been performed specifically for a preoperative diagnosis of acalculous gallbladder disease. The histology of all laparoscopic cholecystectomies performed during this year was analysed and it was found that a further 46 patients had histological specimens that demonstrated the absence of gallstones in the presence of an intact gallbladder specimen. These patients were therefore included in the study group for acalculous gallbladder disease. All patients were sent a questionnaire comparing their state of health before and after surgery.
  
  
  RESULTS
  After laparoscopic cholecystectomy, 66% of patients were completely pain free. The remainder, however, experienced infrequent, moderate pain with occasional pain on eating. Following surgery, all patients were able to conduct their activities of daily living without any limitation.
  
  
  CONCLUSIONS
  We therefore conclude that laparoscopic surgery for patients with acalculous gallbladder disease is effective in symptom control and allowing patients to return to their normal lifestyle.
