Minimal versus definitive surgery in managing peptic ulcer bleeding: a population-based cohort study

Area of Science:

• Gastroenterology
• Surgical Oncology
• Clinical Epidemiology

Background:

• Peptic ulcer bleeding is a significant cause of morbidity and mortality.
• Surgical intervention is sometimes required for refractory cases.
• The optimal surgical approach, minimal versus radical, remains debated.

Purpose of the Study:

• To compare the survival rates of patients undergoing minimal surgery versus radical surgery for bleeding peptic ulcers.
• To evaluate the impact of surgical approach on overall survival in a large cohort.

Main Methods:

• A Swedish nationwide population-based cohort study (1987-2008) analyzed 4,163 patients.
• Propensity score matching was used to create comparable groups for minimal and definitive surgery.
• Cox regression models estimated hazard ratios (HRs) and 95% confidence intervals (CIs) for survival outcomes.

Main Results:

• No significant difference in survival was observed between minimal and definitive surgery groups during the full study period.
• HRs for death in the definitive surgery group were consistently close to 1.0 across different time points.
• In the post-2000 subgroup, minimal surgery showed a trend towards better long-term survival, though not statistically significant.

Conclusions:

• Minimal surgery for peptic ulcer bleeding is associated with comparable overall survival to more extensive procedures.
• A minimal surgical approach appears sufficient for most patients with refractory peptic ulcer bleeding.
• Emerging evidence suggests potential long-term survival benefits with minimal surgery in recent years.
