Lumevis ™: a new medical device to prepare patients for esophagogastroduodenoscopy. Experimental clinical study.

BACKGROUND

Esophagogastroduodenoscopy (EGDS) is the gold standard exam for upper gastrointestinal diseases. EGDS is very important in Early Gastric Cancer diagnosis and treatment but it is an operator-dependent exam and there are lots of factors that reduce its visibility (mucus, bubbles and foam).

AIM: The aim of our study is to evaluate if the use of Lumevis™ improves mucosa visualization during EGDS without increasing the examination time and complications' rate and comparing the differences in patients prepared with water or no intervention.

MATERIALS AND

METHODS

we recruited 50 patients from 01/08/2020 to 31/08/2020 who came to our observation for epigastric pain, dyspepsia and gastroesophageal reflux (GERD). For each patient we evaluate the satisfaction of the procedure, vision quality, EGDS duration and the presence of bubbles following the administration of: nothing (group 1); 50 ml of water alone (W) (group 2); W + simethicone (S) 150 mg+N-acetylcysteine (NAC) 250 mg+10% acetic acid 2.5 ml (group 3); W+S 100 mg + NAC 300 mg + 10% acetic acid 2 ml (group 4); W + S 100 mg + NAC 200 mg + 10% acetic acid 1.5 ml (group 5).

RESULTS

Our results suggest that the lesion detection rate improves with the use of simethicone, acetylcysteine and acetic acid prior to EGDS, although this needs to be studied prospectively.

CONCLUSIONS

Lumevis™ is proposed as a new product in the routine preparation of all patients who have to undergo an EGDS, raising the level in the quality of the exam.
