Laparoscopic cholecystectomy in the geriatric population

To assess effectiveness and conversion rates of inpatient laparoscopic cholecystectomy in older people living in the community.

All acute care hospitals providing cholecystectomy in a single state. Medicare patients who underwent inpatient cholecystectomy in fiscal year 1994 in Arkansas.

A random sample comprising 449 of 2182 geriatric patients who underwent inpatient cholecystectomy in fiscal year 1994, stratified by hospital bed size, had charts reviewed for type of cholecystectomy performed, occurrence of conversion from a laparoscopic to an open cholecystectomy, surgical complications, and need for transfusion.

Eighty-two percent of nonincidental cholecystectomies were initially laparoscopic. Total conversion rate for all inpatient laparoscopic cases was 20%. Forty-two percent of this group suffered acute cholecystitis with male patients exhibiting a higher rate of acute cholecystitis than female patients. Conversion rates for elective cholecystectomy for both sexes was between 13 and 14%. Conversion rate to an open procedures was 28% for patients with acute disease, with male patients again having a higher rate than female patients (40% vs 19%, P < .001). Surgical complications and intraoperative transfusions were rare. Conversion rates did not vary between large and small hospitals or among different age groups within the older population.

Inpatient laparoscopic cholecystectomy is common in older people both for acute and chronic gallbladder conditions. Conversion rates ranged from 13% for elective cholecystectomy to 28% for acute disease. These rates are higher than published literature, which focuses on younger populations undergoing elective procedures. Audit committees need to be aware of this higher conversion rate in older people when assessing surgical proficiency.
