Feasibility and Challenges of Pyeloureteral Magnetic Anastomosis Device in Domestic Pigs: A Stepwise Approach with Extended Observation.

Objective:  The pyeloureteral anastomosis remains the most challenging part of pyeloplasty. A purpose-built anastomotic device could simplify this step and potentially improve outcomes. The concept of a pyeloureteral magnetic anastomosis device (PUMA) was proven in minipigs, but only in short term.

Cheap and clean dry balloon training model for laparoscopic pyeloplasty.

Simulation-based training (SBT) has a significant role in training in complex procedure like laparoscopic pyeloplasty. We propose a new training model for laparoscopic pyeloplasty which has been compared to other models. Trainees (n = 22) evaluated our balloon model (BM) and three other models -glove finger model (GFM), chicken thigh model (ChTM) and chicken crop model (ChCrM)- subjectively, based on a 5-point Likert scale.

Esophageal Magnetic Anastomosis Device (EMAD) to Simplify and Improve Outcome of Thoracoscopic Repair for Esophageal Atresia with Tracheoesophageal Fistula: A Proof of Concept Study.

Background: We designed a new Esophageal Magnetic Anastomosis Device (EMAD) for thoracoscopic repair of esophageal atresia (EA) with tracheoesophageal fistula (TEF) without the need of handheld suturing or additional gastrostomy.

Methods: Synthetic EA-TEF model: Spherical and tubular shaped rubber balloons and a term infant sized plastic doll were used. Medical students (n = 10) and surgical trainees (n = 10) were asked to perform thoracoscopic repair of an "EA" with a hand sutured anastomosis (HA) and with the EMAD.
