Primary duodenal gastrinomas are now recognized as a common etiology for patients with sporadic Zollinger Ellison Syndrome (ZES); however, the clinical and pathologic features of this condition and long-term outcome after operation are not well characterized. ⋯ Duodenal gastrinomas in patients with sporadic ZES are frequently small, most commonly located in the proximal duodenum, and associated with regional lymph node metastases in 60%. Disease-free survival is lower for patients with regional lymph node metastases suggesting that a more systematic lymphadenectomy to extirpate occult disease may be indicated in this group.

Randomized Controlled Trial Comparative Study Clinical Trial
Hilar dissection versus the "glissonean" approach and stapling of the pedicle for major hepatectomies: a prospective, randomized trial.
A randomized study was conducted of hilar dissection and the "glissonean" approach and stapling of the pedicle for major hepatectomies to contrast their feasibility, safety, amount of hemorrhage, postoperative complications, operative times, and costs. ⋯ The 2 techniques are equally effective procedures for treating hilar structures. Although en bloc stapling transection is faster, hilar dissection was associated with a shorter pedicular clamping time, less cytolysis, and the materials required were less expensive.

The aim of the study was to determine pre- and intraoperative risk factors for the development of postoperative delirium among patients undergoing aortic, carotid, and peripheral vascular surgery to predict the risk for postoperative delirium. ⋯ Postoperative delirium after vascular surgery is a frequent complication. A model based on pre- and intraoperative somatic and psychiatric risk factors allows prediction of the patient's risk for developing postoperative delirium.

To evaluate the postoperative cytology of drained fluid from the pancreatic bed as a predictive indicator of local recurrence after curative (R0) resection of pancreatic cancer. ⋯ Drain-cytology was a quick examination that enabled us to specifically indicate both minute residual cancer and subsequent development of local recurrence even after R0 resection of pancreatic cancer.

To evaluate the feasibility of an aggressive surgical approach incorporating major hepatic resection after biliary drainage and preoperative portal vein embolization for patients with hilar bile duct cancer. ⋯ Extensive resection, mainly extended right hemihepatectomy, after biliary drainage and preoperative portal vein embolization, when necessary, for patients with hilar bile duct cancer can be performed safely and is more likely to result in histologically negative margins than other resection methods.
