Diagnostic Use Of A Cap-Assisted-EGD To Evaluate The Oesophagus And Cardia (K III-STUDY)
Aims Our aim was to evaluate the impact of a cap-assisted approach for diagnostic evaluation of the oesophagus compared to a standard esophagogastroduodenoscopy (EGD).
Methods This was a prospective multi-centric randomised controlled study. Subjects scheduled for elective EGD were randomized to undergo either standard EGD or cap-assisted-EGD. All lesions, number of biopsies, duration of examination, sedation doses and histology results were documented.
Our primary outcome was to compare the number of all detected lesions in the oesophagus between standard and cap-assisted-EGD. Secondary outcome measures were subclassification of lesions in the oesophagus, number of lesions in the upper gastrointestinal tract, sedation, number of oesophageal biopsies and their histology, and overall complications.
Results We included 1000 patients, 500 of whom received a cap-assisted-EGD. In the cap-assisted group, one or more lesions could be detected in 280 patients (1 lesion: n= 188, 2 lesions: n = 75, 3 lesions: n= 16, 4 lesions n = 1) in comparison to 264 patients in the standard group (1 lesion: n = 160, 2 lesions: n = 82, 3 lesions: n = 18, 4 lesions: n = 4) (p = 0,84).
Among the secondary outcomes, only endoscopic suspicion of Barrett’s oesophagus (BE) was significantly more frequent within the cap-assisted group (n = 81) vs the standard EGD group (n = 58), (p = 0,039). However, the histologic correlation rate between these lesions was not statistically significant (p = 0,177).
Conclusions For routine examination of the oesophagus a cap-assisted-EGD does not seem to be superior to standard EGD regarding the detection rate of oesophageal lesions.
Although the rate of endoscopic suspicion for BE was higher using a cap-assisted approach, this could not be confirmed histologically.
