Mucosal changes in the gastric stump 20-25 years after partial gastrectomy

Area of Science:

• Gastroenterology
• Oncology
• Surgical Pathology

Background:

• Partial gastrectomy is a common procedure for peptic ulcers.
• Long-term surveillance of gastric remnants is crucial due to potential complications.

Purpose of the Study:

• To assess the incidence of gastric stump carcinoma and precancerous lesions in patients with a history of partial gastrectomy.
• To evaluate the efficacy of endoscopic screening in detecting early-stage gastric cancer in this high-risk group.

Main Methods:

• Endoscopic examination with multiple biopsies was performed on 108 patients 20-25 years after partial gastrectomy for benign ulcer disease.
• Histopathological analysis of biopsy specimens was conducted to identify malignancy and precancerous changes.

Main Results:

• Four patients (3.7%) were diagnosed with gastric stump carcinoma, three with intramucosal carcinoma.
• Three additional patients had severe dysplasia (carcinoma-in-situ).
• The majority of gastric remnants showed varying degrees of dysplasia, metaplasia, or chronic atrophic gastritis.

Conclusions:

• Patients with a history of partial gastrectomy for benign lesions are at significantly increased risk for developing gastric stump carcinoma.
• Endoscopic surveillance with multiple biopsies, particularly around 20 years post-operation, can facilitate early detection of gastric stump cancer.
• Early diagnosis of gastric stump carcinoma may lead to improved patient prognosis.
