Giant cavernous hemangioma of the liver with satellite nodules: Aspects on tumour/tissue interface: A case report.

Background: Giant hepatic cavernous hemangioma with multiple satellite nodules is a rare subtype of hepatic cavernous hemangioma, the most common vascular liver tumor. We report on a tumor with unusual histologic features: (1) Finger-like infiltration pattern; (2) lack of encapsulation; (3) blurred tumor/liver interface; and (4) massive satellitosis-referring to the article "Hepatic cavernous hemangioma: underrecognized associated histologic features".

Case Summary: A 60-year-old man presented with increasing uncharacteristic abdominal discomfort and mildly elevated blood parameters of acute inflammation.

Effectiveness of triclosan-coated PDS Plus versus uncoated PDS II sutures for prevention of surgical site infection after abdominal wall closure: the randomised controlled PROUD trial.

Background: Postoperative surgical site infections are one of the most frequent complications after open abdominal surgery, and triclosan-coated sutures were developed to reduce their occurrence. The aim of the PROUD trial was to obtain reliable data for the effectiveness of triclosan-coated PDS Plus sutures for abdominal wall closure, compared with non-coated PDS II sutures, in the prevention of surgical site infections.

Methods: This multicentre, randomised controlled group-sequential superiority trial was done in 24 German hospitals.

Peri-operative and complication management for adenocarcinoma of the oesophagus and oesophagigastric junction.

Surgical resection of oesophageal cancer still offers the only chance of cure for this disease. Nevertheless, oesophageal surgery may be accompanied by relevant mortality and morbidity, the causes of which can be both directly related to surgical technique as well as a large spectrum of non-surgical complications. In the last few years, improvements in patient selection and technical advances, as well as elaborated peri- and post-operative management, have helped to reduce these threats.

Portal vein arterialization increases hepatocellular apoptosis and inhibits liver regeneration.

Background: Portal vein arterialization is performed in particular situations to guarantee sufficient blood flow in the portal vein. In addition, some authors have postulated a proliferation-promoting influence of portal vein arterialization on the liver tissue. However, portal vein arterialization is an unphysiological procedure: It increases portal blood flow and blood pressure as well as oxygenation of the liver tissue.

Competition between native liver and graft in auxiliary liver transplantation in a rat model.

The competition between the native and the grafted liver in heterotopic auxiliary liver transplantation (HALT) with portal vein arterialization (PVA) was investigated in a rat model. The experimental groups were: HALT with flow-regulated PVA and 70% resection of a native liver and graft (n = 32; group I) versus 70% liver resection (n = 32; group II). After HALT, the weight of the native liver increased until the sixth postoperative week (431% +/- 55% of the intraoperative weight), whereas, the graft weight was only 76% +/- 31% of the intraoperative weight at this time.
