Total Pancreatectomy for Multicentric Cystic Neuroendocrine Tumor of the Pancreas: A Case Report.

Pancreatic neuroendocrine tumors (PNETs) are uncommon pancreatic neoplasms with malignant potential, heterogeneous clinical behavior, as well as imaging appearance. These tumors represent less than 3% of all pancreatic neoplasms with typical CT presentation as solid, well-circumscribed, hypervascular lesions. Cystic PNET is a rare pancreatic tumor which is nowadays more often detected due to the widespread use of high-resolution cross-sectional imaging.

Low-grade fibromyxoid sarcoma of the liver: A case report.

Background: Low grade fibromyxoid sarcoma (LGFMS) is a rare and benign mesenchymal tumor with indolent course, most commonly found in young or middle-aged men. The majority of the LGFMSs are located in the trunk and deep soft tissue of the lower extremities. They appear as well circumscribed, although not encapsulated, which often leads to incomplete surgical resection.

Standard versus extended lymphadenectomy in radical surgical treatment for pancreatic head carcinoma.

Purpose: The primary aim of this study was to evaluate the benefit of extended lymphadenectomy in pancreaticoduodenectomy (PD) and to estimate its impact on long-term survival in patients with pancreatic head carcinoma. Secondary endpoints included perioperative mortality, postoperative morbidity and predictors of survival in patients undergoing standard versus extended lymphadenectomy for pancreatic head carcinoma.

Methods: From January 2007 to December 2010, 60 patients with potentially resectable pancreatic head carcinoma were operated using pylorus-preserving pancreatoduodenectomy (PPPD) at the Clinic for Digestive Surgery, Clinical Center of Serbia, Belgrade.

Pathologic Subtypes of Ampullary Adenocarcinoma: Value of Ampullary MDCT for Noninvasive Preoperative Differentiation.

Objective: The purpose of this study was to evaluate the utility of ampullary MDCT in the noninvasive, preoperative differentiation of pancreatobiliary and intestinal subtypes of ampullary adenocarcinoma.

Materials And Methods: This retrospective study included 32 patients (20 men, 12 women; age range, 41-81 years) with resected ampullary adenocarcinoma who underwent preoperative contrast-enhanced ampullary MDCT. Two radiologists, blinded to pathologic diagnosis of adenocarcinoma subtype, evaluated the presence of seven MDCT features independently.

The importance of choice of resection procedures in T1 and T2 stage of carcinoma of the ampulla of Vater.

Purpose: The ampulla of Vater (AV), with its strategic location and its remarkable predisposition to the development of various malignant tumors, makes it very challenging for surgery. In this study we aimed to examine the prognostic factors in the treatment of early-stage carcinoma of the AV as well as to contribute to the choice of optimal surgical procedure.

Methods: We analyzed 109 AV patients, hospitalized at the Clinical Center of Serbia from January 1999 to December 2008 and we compared the clinicopathological features, analyzed intra- and postoperative data, recurrences and survival, according to duodenopancreatectomy (DP) or local resection (LR).

Acinetobacter spp. colonization and infection risk factors in surgical patients.

Introduction: The results of numerous studies carried out over the last two decades have increasingly important cause of intrahospital infections (IHI). The aim of the study was to determine potential differences in distribution of individual risk factors between the group of patients in whom multiresistant Acinetobacter spp. was isolated and the group of patients in whom it was not.
