Objectives

Narrative objectives1

The enteric nervous system is an autonomous nervous system essential for intestinal peristalsis, mucus secretion, and blood flow regulation, and consists of the intermuscular plexus (Auerbach's plexus) located between the longitudinal and circular muscles and the submucosal plexus ( Meissner's plexus) located in the submucosal tissue. If the detailed distribution of the enteric plexus in the human gastrointestinal tract is known, it may be possible to consider surgical techniques (extent of resected intestinal tract) based on this distribution. It may also be applicable to the diagnosis of diseases of abnormal gastrointestinal tract function caused by congenital absence of nerve plexus in the intestinal wall, such as Hirschsprung's disease.
Recently, Raman spectroscopy, which analyzes molecular structure based on molecular vibration information when a substance is irradiated with light, has been applied to real-time in vivo monitoring, and is attracting attention as a new diagnostic method (optical biopsy) to replace intraoperative rapid pathological diagnosis in malignant tumors.
The purpose of this study is to realize a novel optical diagnostic technique for non-invasive and real-time visualization of the nerve plexus in the intestinal wall by Raman spectroscopy.

Other related information

Raman spectroscopic analysis is performed on resected organs of patients undergoing surgery at the Department. Specifically, organs to be resected for gastrointestinal cancer and inflammatory bowel disease are subjected to Raman spectroscopic analysis immediately prior to resection to identify the nerve plexus in the intestinal wall.
