Аннотация
CONTEXT: A recently published study hypothesized the concept of 'mesopancreas', defining it as a firm, well-vascularized structure extending from the posterior surface of the pancreatic head to behind the mesenteric vessels.
OBJECTIVE: To verify and define mesopancreas from resection specimens obtained from fresh cadavers.
DESIGN: Postmortem anatomical-pathological study.
SETTING: Department of Surgery in conjunction with the Departments of Forensic Medicine and Pathology, Government Medical College and Hospital, Jabalpur, MP, India.
PARTICIPANTS: Twenty fresh adult cadavers without any intra-abdominal injury or gross intra-abdominal pathology.
INTERVENTIONS: Specimens containing the entire duodenum, pancreatic head and neck, gallbladder, cystic duct, common bile duct, superior mesenteric vessels, inferior vena cava and aorta were removed en-bloc. Gross and histopathological examinations of the specimens were carried out.
MAIN OUTCOME MEASURES: To look for a fibrous sheath or fascia around the retropancreatic structure purported to be a mesopancreas.
RESULTS: Loose areolar tissue, adipose tissue, peripheral nerve, nerve plexus, lymphatic and capillaries were found in the retropancreatic tissue, extending from the head, neck and uncinate process of pancreas to the aorto-caval groove but no fibrous sheath or fascia was found around these structures.
CONCLUSIONS: The concept of 'mesopancreas' is anatomically unfounded.
