Survival after peptic ulcer perforation: a time trend analysis

Area of Science:

• Gastroenterology
• Surgical Outcomes
• Epidemiology

Background:

• Peptic ulcer perforation is a serious condition with significant mortality.
• Understanding long-term survival trends is crucial for improving patient outcomes.

Purpose of the Study:

• To analyze survival rates of patients with ulcer perforation.
• To identify factors influencing excess mortality in these patients.
• To examine trends in survival over a 38-year period.

Main Methods:

• Comparative survival analysis of 1098 patients with ulcer perforation against expected population survival.
• Cox regression models were employed to assess the impact of sex, age, birth year, and calendar year on excess mortality.
• Data spanned the period 1952-1990 in Norway.

Main Results:

• Patients with ulcer perforation exhibited lower survival than the general population over 38 years.
• Women experienced lower relative survival than men due to delayed treatment.
• Praepyloric perforations were associated with poorer long-term survival.
• While early treatment periods (1952-1970) showed better relative survival, adjustment for birth year revealed improved short-term mortality over time.
• Younger birth cohorts faced higher relative mortality, suggesting more severe underlying etiologies.

Conclusions:

• Despite advancements in management leading to reduced short-term mortality, long-term survival for ulcer perforation remains a concern.
• Delayed treatment in women and specific perforation types contribute to poorer outcomes.
• An increasing trend in severe etiologies among younger birth cohorts warrants further investigation.
