Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

62
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Summary
This summary is machine-generated.

Indocyanine green fluorescence angiography (ICG-FA) helps surgeons change section lines in colorectal surgery. Age over 60 and longer visualization times are key factors influencing this decision.

Area of Science:

  • Surgical Oncology
  • Medical Imaging

Background:

  • Indocyanine green fluorescence angiography (ICG-FA) provides objective vascular supply evaluation in colorectal surgery.
  • ICG-FA enables intraoperative adjustments to the planned section line (CSL).

Purpose of the Study:

  • To report the clinical experience with ICG-FA guided CSL in colorectal surgery.
  • To identify risk factors associated with ICG-FA determined CSL.

Main Methods:

  • Prospective enrollment of 400 patients undergoing colorectal surgery with anastomosis and ICG-FA from 2014-2023.
  • Patients were divided into Group A (no CSL needed) and Group B (CSL determined by ICG-FA).

Main Results:

  • CSL was required in 16.5% of patients (Group B).
  • Group B showed a significantly longer median time from ICG injection to fluorescence visualization (TIFV) (28.5s vs 23s).
Keywords:

  • Anastomotic leakage rates were 1.8% (Group A) and 4.5% (Group B), not statistically significant. Age > 60 and TIFV ≥ 20s were independent risk factors for CSL.

    • Conclusions:

    • Identified factors influencing CSL can guide the mandatory use of ICG-FA.
    • These factors aid surgical decision-making, including the use of protective ileostomy.
