Survival until 6 years after cholecystectomy: female population of Denmark, 1977-1983.

It has been a prevailing assumption that cholecystectomy patients by and large follow a pattern of survival similar to that of the normal population. This paper presents a population-based study of the long-term survival after cholecystectomy in order to reassess this assumption. Based on data available in the Danish National Hospital Register the records of all Danish women who were operated between 1977 and 1981 were examined and studied up to 6 years subsequent to surgery. Cholecystectomy patients who were free of diagnosed cancer and who had no major co-surgery (n = 11,123) were compared to both hysterectomy patients and a sample of the female population. Adjusting for age and other covariates, patients with psychiatric hospital admissions prior to surgery experienced a threefold risk of dying within 6 years after surgery. Patients with prior somatic admissions and patient with acute admissions had a relative risk (RR) of about 1.5. Cholecystectomy patients had a significantly increased mortality when compared to hysterectomy patients, RR = 1.3 (1.1-1.6), and to the population sample. Heart diseases and cancer occurred significantly more often as causes of death among cholecystectomy patients when compared to hysterectomy patients, but our data suggest that the occurrence of many other causes of death may be increased among cholecystectomy patients as well. The authors concluded that cholecystectomy patients are subject to relatively higher levels of mortality than previously assumed in parts of the literature. Furthermore, the increase seems to be attributable to a multitude of causes of death. The most likely explanation of the excess mortality among cholecystectomy patients is that gallbladder patients are relatively fragile.(ABSTRACT TRUNCATED AT 250 WORDS)

Early postoperative mortality following cholecystectomy in the entire female population of Denmark, 1977-1981.

This paper assesses the risk of dying within 30 days of admission among 13,854 women who had a cholecystectomy performed as the principal operation from 1977 to 1981. The overall crude mortality rate was 1.2%. Women who had a simple elective cholecystectomy performed had a mortality rate similar to women who had a simple hysterectomy. The mortality was significantly higher than in the general female population (p less than 0.05). Increased age, acute admission, admissions to hospital within 3 months prior to the index admission, the number of discharge diagnoses, and the geographical region were significantly associated with increased mortality. Exploration of the common bile duct was associated with higher mortality in the bivariate analysis, but the association disappeared when the number of discharge diagnoses was taken into account. Type of hospital and the population based cholecystectomy rate of the patient's residential area was not associated with mortality. As regards early mortality, it is concluded that simple elective cholecystectomy is a safe procedure before the age of 50 to 60 years. Acute admissions and more than one diagnosis at discharge were associated with an increased mortality, whereas exploration of the common bile duct may not be as important an independent factor as previously assumed.
