Mucosal regeneration of gastric ulcer confirmed by electronic endoscopy
Abstract
We studied the detailed surface structure and changes in the regenerated mucosa during the course of healing of recurrent gastric ulcers treated with lansoprazole or famotidine, using a magnifying electronic endoscope (videoendoscope) and a dye contrast method. The detailed patterns of regenerated mucosa were classified into five types: membranous, spindle-shaped, palisade-shaped, cobblestone-shaped, and almost normal structure. Initially, the membranous regenerated mucosa appears at the ulcer margin and grows into the spindle- and palisade-shaped regenerated mucosa. These latter types of mucosa change gradually into the cobblestone-shaped type, which finally develops into an almost normal structure. Lansoprazole appeared to bring about more rapid growth and changes of the regenerated mucosa than famotidine, although the difference was not statistically significant. We suggest that it is useful, in the assessment of gastric ulcer therapy, to observe the detailed patterns of the regenerated mucosa during the healing process using a magnifying electronic endoscope.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
