Enteric neuronal network (ENS) visualization methods
1) proper muscle full thickness biopsy. no-hole dual EMR
2) endocytoscopy
3) endomicroscopy: eCLE (endoscopy-based confocal laser endomicroscopy) pCLE (probe-based), nCLE (needle-based)

Heterogeneity of results
- ethnic difference
- multiple pathophysiologies
- different sample phenotype
- inadequate sample size
- incorrect analysis or statistics
- incorrect methodology
- selection bias of positive results in the journal
- poor quality of reviewers in this field
