title: Laparoscopic cholecystectomy for the various types of gallbladder inflammation: a prospective trial.
abstract: Laparoscopic cholecystectomy (LC), the procedure of choice for elective cholelithiasis, is now also used in the management of acute cholecystitis. In the various types of gallbladder disease, favorable and unfavorable conditions may influence the conversion and complication rates. Information about these conditions may help elucidate the optimal circumstances for LC or indicate when the procedure is best avoided. We attempted to perform emergency LC on 215 patients with acute cholecystitis. The procedure was successful in 171 patients (79.5%), and conversion to open cholecystectomy (OC) was needed in 44 (20.5%). Complications occurred in 37 patients (17%). Uncomplicated acute cholecystitis was associated with age <50 years, duration of complaint <48 h, temperature <38.5 degrees C, a nonpalpable gallbladder, and an alkaline phosphatase >100 U/L. Acute gangrenous cholecystitis was associated with a negative gallbladder history, other associated diseases, temperature >38.5 degrees C, a palpable gallbladder, and serum bilirubin levels <1 mg/dl. Hydrops was associated with a temperature <38 degrees C and a leukocyte count of >12,000/cc3, and empyema of the gallbladder was associated with duration of complaint >48 h and a palpable gallbladder. The conversion rate of acute gangrenous cholecystitis (40%) was significantly higher than that of uncomplicated acute cholecystitis (8%) (p < 0.00001, odds ratio=7.7), as well as that of empyema of the gallbladder (12.5%) (p=0.005, odds ratio=4.7). The conversion from LC to OC in uncomplicated acute cholecystitis was associated with male sex and with duration of complaint >24 h, and in gangrenous cholecystitis with age >60 years, a nonpalpable gallbladder, and a leukocyte count of >15,000/cc3. The complication rates of acute cholecystitis, hydrops, empyema of the gallbladder, and gangrenous cholecystitis were 16%, 7%, 22%, and 21%, respectively (p = NS). The total complication rate in acute cholecystitis tended to be associated with a duration of complaint >48 h and in gangrenous cholecystitis with male sex, age >60 years, other associated disease, larger bile stones, and elevated serum bilirubin levels. Generally, LC is safe in all forms of cholecystitis, with acceptably low conversion and complication rates, excluding gangrenous cholecystitis. In gangrenous cholecystitis, a conversion rate of approximately 40% is expected. Predictors of conversion and complications may be particularly helpful in planning the laparoscopic approach to acute gangrenous cholecystitis. Patients >60 years of age, with a nonpalpable gallbladder and with a leukocyte count >15,000/cc3, frequently need conversion. In men >60 years old, with other associated disease, with larger bile stones, and with elevated serum bilirubin levels, complications are frequently expected. Under these conditions, laparoscopic approach should be undertaken by especially experienced teams, or OC should be considered.
