“…The diagnostic value of chromoendoscopy and magnified endoscopy has been described in the stomach, colon, and Barrett's esophagus [14,15,18,19]. However, particularly in the stomach, the existence of mucus prevents cell staining with methylene blue, making magnifying chromoendoscopy examination difficult.…”

Background: The conventional endoscopic Congo red test (CRT) permits visualization of acid‐producing mucosa. However, the CRT has not been disseminated into clinical endoscopy, which is partly due to the substantial prolongation of the gastroscopic examination. Methods: Five healthy volunteers and 551 patients were included in a study designed to develop a more rapid approach based on the CRT. In this modified endoscopic Congo red test (MCRT), 0.2 µg/kg of pentagastrin was given intravenously to stimulate gastric acid production. The technical feasibility, tolerability, reproducibility, and inter‐ and intra‐observer reliability of the MCRT were evaluated. Results: The MCRT was as effective as the CRT (i.e. 6 µg/kg of pentagastrin was administered intramuscularly) in visualizing the extent of acid‐producing gastric mucosa. Moreover, the MCRT significantly reduced the duration of examination by 63% (almost 8 min), compared to the CRT. Conclusions: This MCRT is a simple, inexpensive, well‐tolerated and reproducible method with low inter‐ and intra‐observer variability and is well suited for endoscopy units with high workloads.

“…Classes 1 and 2 of the Kudo classification are attributed to hyperplasia, whereas classes 3-6 represent the gradual transition from adenoma to intraepithelial neoplasia and carcinoma. Repeatedly, a close correlation between pit pattern and histology has been confirmed [25,[56][57][58][59][60]. Nevertheless, there remains some controversy as to whether this innovative approach is essential in clinical practice and whether it justifies the additional expense of a magnification video endoscope [53].…”

Chromoendoscopy, the intravital staining of gastrointestinal epithelia, provides additional diagnostic information with respect to the epithelial morphology and pathophysiology. Based on experience gathered mainly in Japan, chromoendoscopy is now in more widespread use, in particular to identify preneoplastic and neoplastic lesions. The most promising techniques are the depiction of squamous epithelium neoplasia of the esophagus with Lugol’s solution, staining of Barrett’s mucosa by methylene blue, including the potential to identify neoplasia, and the demarcation of neoplasia with indigo carmine in stomach and colon for local endoscopic resection. However, the optimal methodology is still to be defined as well as diverging results of diagnostic accuracy to be clarified. High-resolution and magnifying endoscopy have breathed new life into chromoendoscopy. Innovative applications and refinement of the existing ones are soon to be expected.
