Laparoscopic ventral hernia repair is widely used although its clinical indications are often debated. The aim of this study is to describe our surgical experience in order to establish the safety, efficacy, feasibility of laparoscopic ventral hernia repair and to identify the factors that influence the risk of recurrence in a group of patients treated with only one type of prosthetic mesh and by the same surgical team. ⋯ Laparoscopic repair of ventral hernia using composite mesh is an effective and safe procedure particularly suitable in the following cases: median and paramedian defects, diameter of defect between 5 and 15 cm, "swiss cheese" defects, obesity. In our experience the factors related to the patient and the surgical technique that may influence the onset of early or late recurrence as the follows: a defect size >5 cm (W2 of EHS Classification), an overlap of the mesh < 5 cm, a BMI of 30 kg/m2 or superior and the presence of significant comorbidities (ASA score: 3). Finally, we observed that the T.A.P. Block preoperative procedure can lead to reduced the clinical costs through a lower administration of analgesics used and a lower length of stay.

Unilateral and bilateral antegrade cerebral perfusions (ACP) are recognized methods of cerebral protection in aortic arch surgery. However, the adequacy of cerebral protection in aortic arch surgery with deep hypothermic circulatory arrest is controversial. In this study, we compared unilateral and bilateral ACP of cerebral protection in aortic arch surgery by assessing the patient's intraoperative and postoperative brain function. ⋯ When the duration of DHCA was 25 min or less, no significant differences were observed between unilateral and bilateral ACP. However, when DHCA exceeded 25 min, bilateral ACP was more effective compared to unilateral ACP. Due to the high variations in circle of Willis as well as increased safety, simplicity, and efficiency, the bilateral ACP approach is preferred over the unilateral technique.
