Computer-assisted laparoscopic repair of "upside-down" stomach with the Da Vinci system

Recently introduced telerobotic surgical systems attempt to elude the inherent limitations of traditional laparoscopic surgery. Four patients (3 male, 1 female) with mixed hiatal and paraesophageal hernias with fixed intrathoracic partial or complete displacement of the stomach were operatively treated using the Da Vinci robotic system. Tissue dissection, hiatoplasty, and anterior hemifundoplication (Dor) were performed with the telerobotic system. There were no surgical complications. The system broke down in the fourth patient due to a software defect. Advantages were seen in terms of the intrathoracic dissection of displaced stomach through a narrow hiatus, intracorporeal suturing due to 6 degrees of freedom plus grasping. At the moment, lack of the appropriate robotic instruments for abdominal surgery as well as the enormous functional cost of the robotic system are considered to be the most significant current impediment to the adoption of robotic abdominal surgery. The continuous evolution and upgrade of the system is quite promising so far. Telerobotic-assisted hiatal hernia operation is feasible with many advantages compared with the traditional laparoscopic approach, especially during the dissection in the mediastinum in patients with intrathoracic stomach. A prospective, randomized trial will be performed later to evaluate the advantages and limitations of robotic compared with traditional laparoscopy. Technological evolution will perhaps diminish the current problems and the cost associated with robotic surgery.
