Laparoscopic robot-assisted diaphragm plication

Minimally invasive approaches to diaphragm plication for eventration include thoracoscopic and laparoscopic techniques. The elevated hemidiaphragm and ribs limit thoracoscopic techniques. We report our modification of the laparoscopic approach using robotic assistance with the da Vinci Surgical System, (Intuitive Surgical Inc, Sunnyvale, CA) to avoid single-lung ventilation, facilitate exposure, and allow more precise placement of plication sutures to achieve an even tension and maximum plication. Critical steps include creation of a small defect in the diaphragm to equalize pressures between cavities and placement of multiple, pledgeted interrupted horizontal mattresses.
