Summary
Dorsal pancreatectomy is a viable surgical option for noninvasive intraductal papillary mucinous neoplasm (IPMN) in patients with pancreas divisum. This approach avoids extensive resection while maintaining normal pancreatic function.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Endocrinology
Background:
- Intraductal papillary mucinous neoplasm (IPMN) is a premalignant cystic neoplasm of the pancreas.
- Pancreas divisum is a common congenital anomaly where the pancreatic ducts fail to fuse during development.
- Acute pancreatitis and new-onset diabetes mellitus can be presenting symptoms of pancreatic neoplasms.
Observation:
- A 45-year-old male presented with acute pancreatitis and recent-onset diabetes mellitus.
- Imaging revealed an intraductal papillary mucinous neoplasm (IPMN) associated with pancreas divisum, involving predominantly the dorsal pancreas without evidence of invasion.
- The patient underwent a limited dorsal pancreatectomy, preserving the gastroduodenal artery.
Findings:
- Pathological examination confirmed noninvasive IPMN involving branch ducts and the cephalic dorsal duct, with a tumor-free margin.
- The patient experienced a transient pancreatic fistula postoperatively.
- Twelve months post-surgery, the patient exhibited normal gastrointestinal function, no exocrine insufficiency, and controlled diabetes, with no signs of recurrence on MRI.
Implications:
- Dorsal pancreatectomy can be a safe and effective organ-sparing procedure for selected cases of noninvasive IPMN in the dorsal pancreas, especially in the context of pancreas divisum.
- This approach may prevent the morbidity associated with total pancreaticoduodenectomy.
- Preserving pancreatic function is crucial for maintaining gastrointestinal and endocrine homeostasis post-resection.
