Summary

Gastric remnant cancer risk increases 15-20 years post-surgery for benign ulcers. Routine endoscopic surveillance with biopsy can detect early dysplasia and adenocarcinoma, enabling timely treatment and cure.

Area of Science:

  • Gastroenterology
  • Oncology
  • Surgical Pathology

Background:

  • Partial gastric resection for benign ulcers increases risk of gastric remnant cancer.
  • Remnant carcinomas are often aggressive and diagnosed late, limiting treatment options.

Purpose of the Study:

  • To evaluate routine endoscopic surveillance for early detection of dysplasia and adenocarcinoma in gastric remnants.
  • To identify patients eligible for curative resection through timely diagnosis.

Main Methods:

  • Yearly flexible gastroscopy and random biopsies were performed on 163 patients >= 10 years post-gastrectomy.
  • Biopsies were analyzed for dysplasia and early gastric adenocarcinoma.

Main Results:

  • Nine patients showed dysplasia; four developed adenocarcinoma.
  • Eight asymptomatic patients with gastric remnant adenocarcinoma (15-29 years post-gastrectomy) were diagnosed.
  • Early detection allowed for curative total gastrectomy in affected patients.

Conclusions:

  • Neoplastic changes in the gastric remnant are time-dependent after gastric resection.
  • Dysplasia on biopsy indicates a higher risk of gastric remnant carcinoma.
  • Aggressive endoscopic surveillance is crucial for high-risk patients.
