    This study found increased cancer mortality, particularly liver, lung, and colorectal cancers, in patients after partial gastrectomy. Cirrhosis also elevated mortality risks, suggesting potential links to postoperative complications.

    Area of Science:

    • Gastroenterology
    • Oncology
    • Surgical Outcomes

    Background:

    • Partial gastrectomy is a common procedure for benign gastroduodenal diseases.
    • Previous analyses showed no increased risk of gastric stump cancer post-surgery.
    • Long-term mortality patterns following gastrectomy require further investigation.

    Purpose of the Study:

    • To examine cancer-specific mortality rates in a large cohort of Japanese patients after partial gastrectomy.
    • To identify specific cancer types with altered mortality risks post-surgery.
    • To explore potential contributing factors to observed mortality trends.

    Main Methods:

    • Retrospective analysis of mortality data from 3,827 Japanese patients.
    • Inclusion criteria: partial gastrectomy for benign gastroduodenal diseases.

  • Exclusion criteria: gastric stump cancer.

    • Main Results:

    • No increase in gastric stump cancer mortality was observed.
    • Significantly higher mortality rates were found for liver, lung, and colorectal cancers.
    • Increased mortality was also noted in patients with pre-existing liver cirrhosis.

    Conclusions:

    • Partial gastrectomy for benign conditions may be associated with increased mortality from specific non-gastric cancers.
    • Postoperative complications like hepatitis, intestinal stasis, or bacterial overgrowth (especially after Billroth II) may contribute to elevated cancer risks.
    • Further research is warranted to elucidate the mechanisms linking gastrectomy and non-gastric cancer mortality.
