“…There is a recent report, however, that the operation in the dog could be performed by resecting the pancreatico-duodenal vessels with the pancreas if only the duodenal branch is identified and spared [2]. The pancreas lies close to the caval and the portal veins, and the uncinate process is going under the portal vein to join the body of the pancreas.…”

“…On the free edge of the pancreas the peritoneum joins together, forming either the mesoduodenum supporting the right pancreatic lobe or a dorsal sheet of the greater omentum containing the left lobe. The uncinate process receives its arterial supply from the distal pancreatico-duodenal artery necrosis [2]. This (uncinate process) is freely mobile, and the blood supply comes from the distal mesoduodenal vessels (Fig.…”

Total pancreatectomy was performed in dogs (n = 5) and pigs (n = 6) using a contact Nd:YAG laser with a wave length of 1060 nm. The fiber was connected to a laser scalpel, and a 1.0-mm-diameter sapphire tip was used. The power was set at 10-12 W with a pulse time of 9.9 s. The animals were followed postoperatively (p.o.) for 1 week, and no mortality, infection, or any other complication were observed. Total pancreatectomy was significantly faster to perform in pigs than in dogs (P less than 0.001). The number of ligatures (P less than 0.05) and the amount of bleeding (P less than 0.05) were significantly less in pigs than in dogs. The present paper describes the anatomy of the pancreas in dogs and pigs, and also the technical procedure of total pancreatectomy in both species is presented. In conclusion, total pancreatectomy is easier to perform in pigs than in dogs. Furthermore, the anatomy of the pancreas in the pig resembles much that in man.

“…The use of the Nd:YAG laser in performing pancreatic resection without duodenectomy was tested against the conventional multiple fine-ligature technique as modified from Eloy et a1 [ 6 ] . The technique is based on meticulous and progressive division of the small branches supplying the pancreas without interfering with the normal blood supply to the duodenum.…”

“…Eight dogs (six mongrel dogs and two beagles) underwent pancreatectomy using the Nd:YAG laser, of which four were staged operations. Ten dogs (seven mongrels and three beagles) underwent pancreatectomy using the traditional multiple fine-ligature technique modified from Eloy et a1 [6] and served as controls. All these dogs underwent a staged operation.…”

Use of Nd:YAG laser in pancreatic resections with duodenal preservation in the dog

et al. 1985

The trend in recent years for treatment of pancreatic carcinoma and occasionally for pancreatitis has been towards total pancreatectomy. The pancreas is also now being harvested for transplantation. Any operative technique that can reduce operating time, blood loss, and associated morbidity and mortality would be of tremendous advantage. The aim of this study was to undertake a total pancreatectomy using the Nd:YAG laser (wavelength 1,060 nm) with a helium neon laser (wavelength 628 nm) incorporated to provide a marker beam. The laser beam was passed into a 400 micron flexible glass fiber enclosed in a 2.5 mm polyethylene cannula, which also served as a conduit for coaxial CO2. The laser was operated in a continuous wave mode, and the fiber exit beam had a divergence of 10 degrees. For photocoagulation and tissue vaporization, peak powers of 50 W were used with 0.5-1 sec pulses. The total pancreatectomy using the Nd:YAG laser was performed in eight dogs, and ten dogs undergoing the conventional operative procedure served as controls. The findings indicate that the Nd:YAG laser could be used effectively and safely. The operating time was considerably diminished (P less than 0.01); the number of ligatures used was smaller; blood loss, graft survival, and duodenal viability were similar. The Nd:YAG laser offers a new therapeutic modality in the performance of tedious and often difficult pancreatic surgery.

“…Its caudal aspect is freely mobile, while the proximal part of the right lobe lies close in relation to the duodenal wall surrounding the main pancreatic duct. The left lobe lies between stomach and colon, beginning near the pylorus and ending at the left kidney, and is approximately 10-15 cm long, and the parenchyma in this lobe completely surrounds the pancreaticoduodenal vessels making dissection in this area tedious, time-consuming, and prone to injury, risking duodenal necrosis [10] . The canine ductal system has two openings, one of which opens close to or accompanies the bile duct and the other approximately 2-5 cm caudal from the other.…”
