title: Laparoscopic cholecystectomy for gallstones: a comparison of outcome between acute and chronic cholecystitis.
abstract: BACKGROUND
  Laparoscopic cholecystectomy (LC) is now a common method of treating symptomatic gallstones, and it is increasingly being requested by the informed general public. Our aim was to evaluate the role of LC for cholelithiasis and to establish its outcome and the effect of gender on the results.
  
  
  METHODS
  Between September 1994 and June 1999, all patients who underwent LC for cholelithiasis were retrospectively reviewed. They were classified as having acute or chronic cholecystitis (AC or CC).
  
  
  RESULTS
  There were 791 patients with CC (633 females, 158 males) and 204 patients with AC (124 females, 80 males). Conversion to open cholecystectomy was needed in 0.76% and 11.8% of the patients with CC and AC, respectively (P<0.00). Four percent of the female patients with AC needed conversion as compared to 23.8% in the males (P<0.00). The low conversion rate in CC limited gender comparison. Median operation time in the patients with CC was 53+/-16 minutes as compared to 74.5+/-35.7 minutes in those with AC (P<0.00). Operation time in the male patients with CC and AC was significantly higher than in the female patients, even after excluding the converted cases (P<0.00). Median postoperative stay for patients with CC was 1.33+/-0.9 days as compared to 1.9+/-1.34 days in patients with AC (P<0.00). No statistical significance in the hospital stay was found between males and females (in CC and AC). There was no mortality in the series. There were three bile duct injuries in the patients with CC. In patients with successful LC, gallbladder perforation occurred in 18% and 31% of CC and AC patients, respectively (P<0.003). Missed stones occurred in 1.4% and 3.3% of the patients with successful LC for CC and AC, respectively. Bile collection, which was treated with open drainage, occurred in four patients with CC and one patient with AC.
  
  
  CONCLUSIONS
  LC for symptomatic cholelithiasis is safe and feasible; it should be the first choice before resorting to open surgery. In patients with AC as compared to CC, there is an increased conversion rate, longer operation time, longer hospital stay, and higher incidence of gallbladder perforation without an increase in the incidence of bile duct injuries (BDI). Male patients have a longer operation time and higher conversion rate than female patients.
