Analysis of recurrence after the resection of pancreatic neuroendocrine tumors.

Background And Objectives: Outcomes after recurrence of resected pancreatic neuroendocrine tumors (PNETs) are not well described. We aim to assess the rate and sites of recurrence, and its effect on clinical outcomes.

Methods: Retrospective chart review of patients (n = 83) who underwent surgical resection of PNETs at 2 institutions.

Clinical outcomes for neuroendocrine tumors of the duodenum and ampulla of Vater: a population-based study.

Background: Previous case series report that neuroendocrine tumors (NETs) of the ampulla of Vater have worse overall survival (OS) than NETs in the duodenum. We aimed to compare the OS of patients with ampullary NETs to patients with duodenal NETs.

Methods: This retrospective comparative cohort study used the Surveillance, Epidemiology, and End Results (SEER) registry from 1988 to 2009.

Outcomes of Cytoreductive Surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) in patients older than 70 years; survival benefit at considerable morbidity and mortality.

Background: Cytoreductive surgery (CRS)/Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is associated with prolonged survival in selected patients with peritoneal surface disease. Yet, for elderly patients (older than 70 years of age) CRS/HIPEC is controversial, due to associated morbidity.

Methods: A retrospective analysis of a prospective database of 950 procedures was performed.

Unnecessary tests and procedures in patients presenting with solid tumors of the pancreas.

Background: A computed tomography (CT) scan is often the only study needed prior to surgery for resectable solid pancreas masses. However, many patients are evaluated with multiple studies and interventions that may be unnecessary.

Methods: We conducted a retrospective review of patients who presented to the Johns Hopkins Multidisciplinary Pancreas Cancer Clinic with a clearly resectable solid pancreas mass, >1 cm in size over a 2-year period (6/2007-6/2009) and underwent resection.

Preoperative endoscopic tattooing of pancreatic body and tail lesions decreases operative time for laparoscopic distal pancreatectomy.

Background: Precise and expedient localization of small pancreatic tumors during laparoscopic distal pancreatectomy can be difficult owing to the decreased tactile ability of laparoscopy and the homogenous appearance of the surrounding retroperitoneal fat. Precise localization of the lesion is critical to achieving adequate margins of resection while preserving as much healthy pancreas as possible. The objective in this study was to determine the effect of endoscopic tattooing of the distal pancreas on operative time.
