The neck of the pancreas was carefully bluntly mobilized off the superior mesenteric vein and portal vein, staying directly in the anterior midline to avoid the multiple branches from the head. The neck was encircled with a Penrose drain.
Pathological diagnosis of the tail lesion was benign islet cell adenoma. The neck lesion consisted of two adjacent adenomas. One was benign, the other, on which enucleation had been attempted, was thought to have a low malignant potential. In addition, there was islet cell hyperplasia and microadenomas in the rest of the gland.
