Pancreatic segmentation on an embryological and anatomical basis

Area of Science:

• Surgical Oncology
• Gastrointestinal Surgery
• Anatomical Studies

Background:

• Limited pancreatic resection is a viable option for low-grade malignancies, particularly mucin-producing tumors.
• Accurate anatomical understanding is crucial for successful limited pancreatic resections.
• Current anatomical divisions may not be optimal for guiding segmental pancreatic surgery.

Purpose of the Study:

• To propose a novel system for segmenting the pancreas to facilitate limited resection procedures.
• To establish an anatomical and embryological basis for this proposed segmentation.
• To improve surgical precision in pancreatic resections for specific tumor types.

Main Methods:

• Development of a four-segment pancreatic division: anterior head, posterior head, body, and tail.
• Integration of conventional anatomical landmarks.
• Consideration of pancreatic developmental origins (ventral and dorsal primordia) and their distribution.

Main Results:

• A proposed segmentation system divides the pancreas into four distinct anatomical segments.
• This system is grounded in both established anatomy and embryological development.
• The segmentation provides a framework for targeted pancreatic tissue removal.

Conclusions:

• The proposed four-segment pancreatic division offers a structured approach for limited resections.
• This anatomical segmentation, based on embryological origins, can enhance surgical planning.
• This system may optimize outcomes for patients undergoing resection of low-grade pancreatic tumors.
