Changes in chest compression indexes with breathing underestimate surgical candidacy in patients with pectus excavatum: a computed tomography pilot study.

Background: Haller Index (HI) ≥3.25 by computed tomography (CT) at end-inspiration has been used to indicate surgical correction in patients with pectus excavatum. However, chest wall diameters vary with breathing and may modify HI values and surgical indications.

Novel hybrid (magnet plus curve grasper) technique during transumbilical cholecystectomy: initial experience of a promising approach.

Objectives: The use of magnets in transumbilical cholecystectomy (TUC) improves triangulation and achieves an optimal critical view. Nonetheless, the tendency of the magnets to collide hinders the process. In order to simplify the surgical technique, we developed a hybrid model with a single magnet and a curved grasper.

Initial experience with magnet-assisted single trocar appendectomy in children.

Background: Single-incision laparoscopic surgery (SILS) is increasingly being used to treat acute appendicitis. Existing SILS techniques suffer from inefficient triangulation and poor ergonomics. In an effort to improve on existing SILS techniques, we developed the magnet-assisted single trocar (MAST) appendectomy.
