AI Article Synopsis
- l-Menthol (LM) is a safe antispasmodic agent used during esophagogastroduodenoscopy (EGD), but it may alter endoscopic findings of gastric lesions.
- A study involving 98 patients assessed the effects of LM versus a placebo, finding significant mucosal changes in the LM group compared to the placebo group.
- Results indicated that LM caused more pronounced changes in atrophic gastric mucosa and helped to better define gastric lesions, though it did not significantly affect the overall incidence of these lesions.
Article Abstract
Background And Study Aims: l-Menthol (LM), sprayed on the distal gastric mucosa, is a safe antispasmodic agent used during esophagogastroduodenoscopy (EGD). However, it seems to affect gastric mucosal endoscopic findings. Therefore, we evaluated whether LM causes specific changes and impacts the endoscopic morphology of gastric lesions.
Patients And Methods: A total of 98 patients scheduled to undergo EGD were randomly assigned to receive LM solution (160 mg of 0.8 % LM added to 2.5 mL of indigo carmine [IC]; n = 49; LM group) or decuple-diluted IC solution without LM (n = 49; placebo group). We compared the incidence of specific mucosal changes and the difference in the endoscopic findings of several gastric lesions between these groups.
Results: Annular-reticular - like mucosal changes appeared immediately after the administration of LM solution. This change was observed in 71.4 % of the LM group compared with 12.2 % of the placebo group (P < 0.01). In the placebo group, this change was observed in 14.7 % of subjects with atrophic gastritis compared with 6.7 % of those without atrophic gastritis (P = 0.39), whereas in the LM group, this change was observed in 84.8 % of subjects with atrophic gastritis compared with 43.8 % of those without atrophic gastritis (P < 0.01). Most early gastric cancers, erosions, and ulcers observed in this study became well demarcated after LM administration, although the incidence of gastric lesions did not differ significantly between the two groups.
Conclusion: LM changes the gastric mucosa into edematous mucosa, and this occurs more frequently in atrophic gastric mucosa than in pathologic lesions. LM may facilitate the demarcation of pathologic gastric lesions without intestinal metaplasia.

Gastric cancer (GC) represents one of the most lethal forms of cancer. When identified at an early stage, conventional treatment can be curative. The key to identifying GC at an early stage is high-quality esophagogastroduodenoscopy (EGD).

Article Synopsis
- L-Menthol was tested for its effectiveness in enhancing the visibility of early gastric cancer (EGC) during endoscopic procedures using linked color imaging (LCI).
- The study found that while 100% of lesions showed a color difference before and after spraying L-menthol, the expected improvement in visibility under LCI was not achieved.
- Despite this, there was a significant increase in color difference measurements after application, with LCI displaying the highest percentage of lesions showing increased color difference compared to white light and blue laser imaging.

L-menthol-containing food products generally show the flavor loss during storage due to their high volatility. The hydrophobicity of L-menthol also causes the inadequate flavor release during rehydration. In this study, the stability of L-menthol was enhanced by microencapsulation and the effect of different powder drying techniques was also investigated.
