Key result
Acute cholecystitis surgery in 1980-1987 linked to ~3 days shorter stay vs 1970-1977 with unchanged mortality.
Why the study?
Surgery for acute cholecystitis is the most frequent abdominal surgery, but aspects of its management remain controversial.
How do patient characteristics and outcomes of surgery for acute cholecystitis compare between the 1970-1977 and 1980-1987 periods?
Comparison
Operations from 1980-1987 (group N) vs 1970-1977 (group O)

Observational cohort study comparing two 10-year intervals

Supports earlier surgery despite sicker patients with stable mortality; leaves open whether timing or selection explains benefits in modern cohorts.

How do patient characteristics and outcomes of surgery for acute cholecystitis compare between the 1970-1977 and 1980-1987 periods?
Absolute Event Rate: 3% vs 2.7%
p-value: p=NS
Over a 10-year interval, surgery for acute cholecystitis evolved to include older, sicker patients operated on earlier, resulting in shorter hospital stays and fewer wound infections without increased mortality.
Reiss et al. (1990) conducted an observational in Acute cholecystitis (n=516). Surgery during 1980-1987 vs. Surgery during 1970-1977 was evaluated on Mortality (p=NS). Surgery for acute cholecystitis in 1980-1987 was associated with no significant difference in mortality (3.0% vs 2.7%) and a 3.2-day shorter hospital stay compared to 1970-1977.
