Laparoscopic cholecystectomy in acute cholecystitis. A prospective comparative study in patients with acute vs.
Background:
The aim of this prospective study was to compare the outcome of laparoscopic cholecystectomy (LC) in patients with acute cholecystitis versus those with chronic cholecystitis and to determine the optimal timing for LC in patients with acute cholecystitis.
Methods:
From January 1991 to July 1998, 796 patients (542 women and 254 men) underwent LC. In 132 patients (67 women and 65 men), acute cholecystitis was confirmed via histopathological examination. These patients were divided into two groups. Group 1 (n = 85) had an LC prior to 3 days after the onset of the symptoms of acute cholecystitis, and group 2 (n = 47) had an LC after 3 days.
Results:
There were no mortalities. The conversion rates were 38.6% in acute cholecystitis and 9.6% in chronic cholecystitis (p<10(-8)). Length of surgery (150.3 min vs. 107.8 min; p<10(-9)), postoperative morbidity (15% vs. 6.6%; p = 0.001), and postoperative length of stay (7.9 days vs. 5 days; p< 10(-9)) were significantly different between LC for acute cholecystitis and elective LC. For acute cholecystitis, we found a statistical difference between the successful group and the conversion group in terms of length of surgery and postoperative stay. The conversion rates in patients operated on before and after 3 days following the onset of symptoms were 27% and 59.5%, respectively (p = 0.0002). There was no statistical difference between early and delayed surgery in terms of operative time and postoperative complications. However, total hospital stay was significantly shorter for group 1.
Conclusions:
LC for acute cholecystitis is a safe procedure with a shorter postoperative stay, lower morbidity, and less mortality than open surgery. LC should be carried out as soon as the diagnosis of acute cholecystitis is established and preferably before 3 days following the onset of symptoms. Early laparoscopic cholecystectomy can reduce both the conversion rate and the total hospital stay as medical and economic benefits.
