Summary

Autoamputation of gastric polyps is rare. This case suggests diabetes mellitus or its medications may cause gastric injury leading to polyp autoamputation.

Area of Science:

  • Gastroenterology
  • Endocrinology

Background:

  • Autoamputation of gastric polyps is an uncommon event with an unclear underlying mechanism.
  • Understanding the process requires direct observation of the polyp before and after spontaneous disappearance.

Observation:

  • A case study documented a 61-year-old woman presenting with hematemesis due to a gastric antrum polyp.
  • Endoscopic examination revealed a bleeding point near the polyp, which had vanished by the following day.

Findings:

  • The study observed the spontaneous disappearance of a gastric polyp via endoscopy.
  • The polyp's autoamputation was documented immediately before and after the event.

Implications:

  • This case suggests a potential link between gastric injury and autoamputation of gastric polyps.

  • Diabetes mellitus and oral antidiabetic drugs are proposed as potential contributing factors to this gastric injury.
