How do we apply video-assisted retroperitoneal necrosectomy with minimal access?

The conservative treatment of acute necrotizing pancreatitis has greatly improved due to broad antibiotic treatment and improved organ support in intensive care units. Nevertheless, infected necrosis or persistent multi-organ dysfunction are predictors of poor outcome. In these patients, there is still a need to perform necrosectomy. Open surgery results in extensive operative trauma and is associated with high morbidity and mortality. Therefore, several minimally invasive techniques have been developed recently. Retroperitoneal necrosectomy has been shown to be safe and to reduce morbidity and mortality compared to the open procedure.

SWIVIT--Swiss video-intubation trial evaluating video-laryngoscopes in a simulated difficult airway scenario: study protocol for a multicenter prospective randomized controlled trial in Switzerland

Video-laryngoscopes are marketed for intubation in difficult airway management. They provide a better view of the larynx and may facilitate tracheal intubation, but there is no adequately powered study comparing different types of video-laryngoscopes in a difficult airway scenario or in a simulated difficult airway situation.

A smart multi-hop hierarchical routing protocol for efficient video communication over wireless multimedia sensor networks

For smart applications, nodes in wireless multimedia sensor networks (MWSNs) have to take decisions based on sensed scalar physical measurements. A routing protocol must provide the multimedia delivery with quality level support and be energy-efficient for large-scale networks. With this goal in mind, this paper proposes a smart Multi-hop hierarchical routing protocol for Efficient VIdeo communication (MEVI). MEVI combines an opportunistic scheme to create clusters, a cross-layer solution to select routes based on network conditions, and a smart solution to trigger multimedia transmission according to sensed data. Simulations were conducted to show the benefits of MEVI compared with the well-known Low-Energy Adaptive Clustering Hierarchy (LEACH) protocol. This paper includes an analysis of the signaling overhead, energy-efficiency, and video quality.
