|Colorectal Cancer Inflammatory Bowel Diseases Gastrointestinal Dysfunction||Device: orthogonal polarization spectral (OPS) imaging|
AIM OF THE STUDY This observational study will assess whether perioperative microcirculatory changes can be correlated with symptoms associated with primary POI.
PRIMARY RESEARCH QUESTION Is there a correlation between peri-operative microcirculatory flow measurements and the incidence of symptomatic primary POI?
SECONDARY RESEARCH QUESTIONS
- Is there a correlation between peri-operative microcirculatory flow measurements and the duration of symptomatic primary POI?
- If any correlation is observed, which anatomic location (sublingual mucosa vs bowel serosa) yields microcirculatory flow measurements that are more strongly associated with the incidence and/or duration of symptomatic primary POI?
- Can either intraoperative sublingual mucosa or intraoperative bowel serosa microcirculatory flow measurements predict symptoms of primary POI? Are these two anatomic locations equivalent in their ability to predict this complication?
|Study Type :||Observational|

Elective colorectal surgeries
Patients undergoing elective colorectal procedures with an Enhanced Recovery Program. Orthogonal polarization spectral (OPS) imaging will be used to measure sublingual microcirculation
Device: orthogonal polarization spectral (OPS) imaging
orthogonal polarization spectral (OPS) imaging allows noninvasive observation of human microcirculation in all accessible tissue surfaces
- Postoperative ileus symptoms; microvascular flow index (MFI) [ Time Frame: Participants will be followed for the duration of hospital stay, an expected average of 3 days ]
Patients will be considered having POI symptoms if at least one symptom, for each of the following criteria, will be reported:
i. Vomiting (+/- nausea) OR abdominal distension AND ii. Absence of passing gas/stool OR not tolerating oral diet.
Microvascular flow index (MFI) score: this score is based on determination of the predominant type of flow observed. Flow is characterized as absent (0), intermittent (1), sluggish (2), or normal (3).
