Key result
Intraoperative bowel viability assessments show promise but lack standardization for routine clinical use.
Why the study?
Intraoperative bowel viability assessment remains an open challenge, and an accurate, cost-effective technique is needed to reduce postoperative morbidity and mortality in abdominal surgery.
What are the available and promising techniques for intraoperative bowel viability assessment during surgery?
What are the available and promising techniques for intraoperative bowel viability assessment during surgery?
While a standardized method is currently lacking, emerging technologies such as NIR angiography, OCT, and autofluorescence spectroscopy show promise for early detection of nonviable bowel segments during surgery.
The problem of bowel viability assessment during surgery is still opened. High value predictive and economically available technique is thought to decrease postoperative morbidity and mortality during elective and urgent abdominal surgery. To evaluate the available techniques for intraoperative bowel viability assessment, the search of Russian and foreign up-to-date literature was performed. Parameters of techniques are analyzed: intraoperative clinical application, invasiveness, objectivity and quantification of viability parameters, predictive value for necrosis and anastomotic leakage. There is still no standardised and available for every operative theatre method for bowel viability assessment during surgery. Numerous of techniques such as near-infrared fluorescence (NIR) angiography, using indocyanine green (ICG), optical coherence tomography (OCT), laser doppler flowmetry (LDF) are proposed to be more evaluated and perspective. Autofluorescence spectroscopy for NADH and flavoproteins seems to be a promising tool for early detection of nonviable bowel segments.

Zacharenko et al. (2020) conducted a review in Bowel viability assessment during surgery. Intraoperative bowel viability assessment techniques (NIR, ICG, OCT, LDF, Autofluorescence spectroscopy) was evaluated on Predictive value for necrosis and anastomotic leakage. Intraoperative bowel viability assessment techniques such as NIR angiography, OCT, LDF, and autofluorescence spectroscopy are promising but currently lack standardization for routine clinical use.
