Giant retroperitoneal liposarcoma: A case report and literature review.

Retroperitoneal liposarcomas are a heterogeneous group of mesenchymal tumours that have a wide spectrum of histological subtypes and vague clinical presentations. Herein, we present the case of a 75-year-old man with anorexia, weight loss of 7 kg, and a growing abdominal circumference within a span of 6 weeks. Computed tomography of the abdomen and pelvis showed a large mass that filled almost the entire abdominal cavity.

The "Nouvelle Vague" of surgeons in pancreatic surgery: can they rise to the legacy of current surgeons?

Purpose: Pancreatic surgery is still thought as a challenging field even for experienced hepatobilliary (HPB) surgeons and high volume tertiary centers. The purpose of this study was to present the results (mortality and morbidity) of pancreatic surgery in a high volume center, in operations performed solely by inexperienced surgeons (two 6th year residents and a HPB fellow) under the supervision of expert surgeons on the field.

Methods: Forty-one consecutive patients who underwent curative-intent pancreatic resection with a modified pancreaticojejunostomy between January 2010 and December 2014 at Asklepios Hospital Barmbek, Germany, were identified from our institutional computer-based database.

Large hemangiopericytoma of the pelvis--towards a multidisciplinary approach.

Background: In 1942, Stout described tumors which derive from Zimmerman's pericytes and suggested the term hemangiopericytoma (HPC). These tumors, which are often highly vascularized, pose difficulties in the surgical management regarding blood loss and complete resection. Therefore, preoperative management seems to be an essential part in dealing with these issues.
