title: The Dagradi-Serio-Iacono operation central pancreatectomy.
abstract: Central pancreatectomy (CP) is a segmental pancreatic resection indicated to remove benign or low-grade malignant tumors of the isthmus and proximal part of the body of the pancreas. The main advantage of this operation compared with major resections is that it permits to spare normal pancreatic parenchyma; moreover, spleen and upper digestive and biliary tracts are saved. The description of the complete operation was reported for the first time by Dagradi and Serio in 1984 and subsequently spread worldwide by Iacono and Serio. In our opinion, it should be called the Dagradi-Serio-Iacono operation, by the names of the surgeons who first performed it (Dagradi and Serio), and by the names of the surgeons responsible for reporting it worldwide with precise indications (Iacono and Serio). Operation requires a midline or a bilateral subcostal incision; the lesser sac is entered through dissection of the transverse colon from the omentum or by transecting the gastrocolic ligament. The pancreatic segment harboring the lesion is then mobilized and its posterior surface carefully dissected from the splenic vein and artery. Subsequently, the pancreatic portion harboring the tumor is isolated at its superior margin from the splenic artery after the pancreas is transacted. The extent of the resection of the central segment is limited on the right by the gastroduodenal artery and on the left by the need to leave at least 5 cm of normal pancreatic remnant. The resected pancreatic specimen is sent to the pathologist for confirmation of diagnosis and to check if the resection margins are adequate. Hemostasis of the two raw surfaces is achieved with interrupted 5 or 4/0 nonabsorbable stitches. When it is not stapled, the Wirsung's duct of the cephalic stump is sutured selectively with a figure-of-eight nonabsorbable stitch. An end-to-end invaginated pancreaticojejunostomy is carried out with a single layer of interrupted stitches. The operation is concluded with the construction of an end-to-side jejuno-jejunostomy about 50 cm distal to the pancreatic anastomosis. Other techniques for reconstruction of the distal stump using jejunum or stomach have been described. One or two soft drains are brought out on the right side. The fluid collected from this drain is checked for amylase level on postoperative days 3, 5, and 7; if the level is low or absent, the drain is removed. Central pancreatectomy is a safe technique for benign or low malignant tumors of the pancreatic neck that allows curing the tumor with evident functional results without increasing the risk for the patient. We can say that CP has a clear role like pancreaticoduodenectomy and distal pancreatectomy and we think that a pancreatic surgeon has to include this procedure in his/her technical skills. In order to obtain excellent results, correct indications and experience in pancreatic surgery are recommended.
