Answer:
Abnormalities of enteric nerves, interstitial cells of Cajal (ICC) and smooth muscle are often associated with severe gastrointestinal motility disorders. In this context, full-thickness biopsy of the gut may provide important diagnostic and prognostic clues as well as some possible therapeutic implications. Nonetheless, the unavoidable risk to further worsen prognosis evoked by laparotomy, and the unclear yield of histopathological analysis has hampered full-thickness gut sampling in patients with severe dysmotility. However, recent advances in minimally invasive surgery have refuelled enthusiasm in gastrointestinal neuromuscular pathology. In this issue of Neurogastroenterology and Motility, Miller et al. provide novel and exciting evidence that the appendix might be used as a surrogate tissue to analyse changes to enteric nerves, ICC and smooth muscle cells in patients with diabetic gastroenteropathy. The objective of this short review was to place this very important work in the context of current understanding of enteric neuromuscular dysfunction.
