Retrocolic Fascia-An Anatomical and Multidetector Computed Tomographic Angiography (MDCTA) Morphometric Analysis in...

Area of Science:

• Anatomical studies
• Surgical oncology
• Radiology

Background:

• Gerota's fascia is a critical posterior landmark for surgical dissection in right-sided colon cancer.
• Understanding its anatomy is crucial for complete mesocolic excision (CME).

Purpose of the Study:

• To delineate anatomical landmarks, specifically Gerota's fascia, for CME in right colon cancer.
• To investigate fascial anatomy and variations under pathological conditions.

Main Methods:

• Pilot cadaveric dissection for anatomical visualization.
• Mimics segmentation for fascial relationship analysis.
• Retrospective analysis of 196 MDCTA scans with systematic thickness measurements.

Main Results:

• Gerota's fascia identified as a distinct retrocolic connective tissue layer.
• MDCTA provided clearer visualization, particularly on the left side.
• Fascial thickness correlated positively with BMI, with no significant effect from age or sex.

Conclusions:

• Gerota's fascia is an indispensable anatomical landmark for CME in right colon cancer.
• The fascia's structural integrity, unaffected by tumors, is vital for surgical navigation.
