Endocrine Function after Duodenum-Preserving Resection of the Head of the Pancreas With or Without Segmental Pancreatic Autotransplantation: An Experimental Study in Dogs

The pancreas forms from the dorsal and ventral endodermal buds, which develop at the foregut-midgut junction. The head of the pancreas lies in the duodenal C-loop, anterior to the IVC and left renal vein. Islets of Langerhans carry out the endocrine function of the pancreas. Acute pancreatitis is caused by gallstones, alcohol, and trauma. CT with an IV contrast agent may be used to diagnose pancreatitis, pancreatic cancer, or complications after pancreatic surgery. Most patients with acute pancreatitis are managed conservatively. Pancreatic leaks occur in approximately 20% of operations on the pancreas.

Illumination Mode

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
