title: [Echo-guided spleen-preserving resection of the pancreas tail for pancreatic intraductal papillary mucinous neoplasms].
abstract: Intraductal papillary mucinous neoplasms (IPMNs) of the pancreas are a distinct entity with malignant potential, which may recur after surgical excision. Limited pancreatectomies have been recently proposed for non-invasive tumours. We report our technique of intraoperative US-guided resection of non-invasive IPMNs located in the tail of the pancreas with spleen and splenic vessel preservation. Following adequate exposure of the distal pancreas, a thorough ultrasonographic examination of the parenchyma is accomplished to define the features of the neoplasia, its relationship with the main pancreatic duct and splenic vessels and to mark the transection line with electrocautery. Dissection begins at the inferior edge of the pancreatic tail and proceeds in a lateral to medial direction up to the transection line. The main pancreatic duct is identified and sutured, the parenchyma is then closed and the suture line is reinforced with a fibrinogen/thrombin-coated collagen patch. Patient 1 was a 63-year-old male who underwent intraoperative US-guided resection of the pancreatic tail for an IPMN of the pancreatic tail measuring 28 mm with moderate dysplasia at histology, and was discharged 9 days after surgery. Patient 2 was a 60-year-old male who underwent intraoperative US-guided resection of the pancreatic tail for an IPMN of the pancreatic tail measuring 30 mm with carcinoma in situ at histology, and was discharged 9 days after surgery. Limited distal pancreatic resection with spleen and splenic vessel preservation is an adequate surgical technique for non-invasive IPMN of the tail of the pancreas. Intraoperative ultrasonography is crucial in planning "radical but conservative" pancreatic resection.
