Anterior Presentation of the Surfaces of the Pancreas

Description

Anteriorly oriented anatomy of the pancreas is laid out with the head nestled in the C loop of the duodenum, the neck crossing toward the midline, and the body and tail extending leftward toward the splenic hilum. The anterior surface (facies anterior) faces the lesser sac, while the inferior surface (facies inferior) turns toward the transverse mesocolon and proximal jejunum. A sharp inferior border separates these aspects along the body, and the posterior surface lies away from the viewer against retroperitoneal structures. From right to left, the gland’s contours emphasize the transition from the broad head to the tapering tail. This anterior presentation matters because the pancreas is approached clinically through spaces that relate directly to these surfaces, not through the retroperitoneum itself. In open or laparoscopic distal pancreatectomy, mobilization often proceeds by entering the lesser sac, identifying the anterior surface of the body, and working along the inferior border where the transverse mesocolon and middle colic vessels can be at risk. Pancreatitis and pancreatic pseudocysts commonly track into the lesser sac, so teaching the anterior surface as a peritoneal-facing landmark helps correlate physical dissection with CT and operative findings. Use this figure in abdominal anatomy and gastrointestinal surgery teaching to anchor discussions of pancreatic relations, peritoneal compartments, and safe planes for exposure of the body and tail. It also suits atlas plates and review articles that need Terminologia Anatomica terms (facies anterior, facies inferior) tied to clear surface boundaries.
