Recurrent pseudocysts and pancreatitis after trauma: a complication of pancreas divisum.

Two patients are described who developed pancreatitis and recurrent pseudocysts after minimal trauma. Both had the congenital anomaly of pancreas divisum, and neither responded to surgical therapy appropriate to patients with normal anatomy. Both patients eventually required excision of the entire dorsal portion of the pancreas for relief. Patients with pancreatitis and pseudocysts should undergo endoscopic pancreatography immediately before surgery to aid in the definition of appropriate surgical therapy.
