Aorto-oesophageal fistula is a rare and often fatal condition due to pathologies of the aorta and oesophagus. Recently, a new aetiology for aorto-oesophageal fistulas has been detected, namely, decubitus of an aortic endovascular prosthesis positioned in the presence of aneurysms. The symptoms are those of Chiari's triad: (1) chest pain and/or dysphagia (2) haematemesis (3) massive haematemesis. If the patient is haemodynamically stable the gold standard diagnostic examination is a CT scan with contrast medium. Aorto-oesophageal fistulas are characterised by a rapidly worsening acute clinical presentation and high postoperative morbidity and mortality. The treatment of aorto-oesophageal fistula is divided into three progressive steps: (1) control of bleeding; (2) prevention of mediastinitis; (3) oesophageal repair. We report a case of a 59-year-old male patient with an aorto-oesophageal fistula due to the decubitus of an endovascular aortic prosthesis previously positioned for a traumatic aneurysm of the descending aorta. We controlled the bleeding in emergency with a Sengstaken-Blakemore tube. Since the cardiovascular surgeons excluded any intervention, we executed a bipolar oesophageal exclusion in our department of general surgery and subsequently positioned a self-expanding oesophageal prosthesis by a retrograde route. The patient survived for 7 months, the cause of death being septic shock.

The benefit of by laparoscopic resection for lesions located in postero-superior segments is unclear. The present series aimed at comparing intraoperative and post-operative results in patients undergoing either laparoscopic RPS or laparoscopic RH for colorectal liver metastases located in the right postero-superior segments.

Obesity can lead to pathological growth of adipocytes by inducing inflammation and oxidative stress. Genistein could be a potential candidate for the treatment of obesity due to its antioxidant properties. Specific kits were used to examine the effects of genistein vs adiponectin on human visceral pre-adipocytes differentiation, cell viability, mitochondrial membrane potential, and oxidative stress in pre-adipocytes and in white/brown adipocytes. Western Blot was performed to examine changes in protein activation/expression. Genistein increased human visceral pre-adipocytes differentiation and browning, and caused a dose-related improvement of cell viability and mitochondrial membrane potential. Similar effects were observed in brown adipocytes and in white adipocytes, although in white cells the increase of cell viability was inversely related to the dose. Moreover, genistein potentiated AMP-activated protein kinase (AMPK)/mitofusin2 activation/expression in pre-adipocytes and white/brown adipocytes and protected them from the effects of hydrogen peroxide. The effects caused by genistein were similar to those of adiponectin. The results obtained showed that genistein increases human visceral pre-adipocytes differentiation and browning, protected against oxidative stress in pre-adipocytes and white/brown adipocytes through mechanisms related to AMPK-signalling and the keeping of mitochondrial function.
