Abstract
The concept of Transumbilical Cholecystectomy with Magnetic Retraction (TCMR) is founded on reproducing classic laparoscopic surgery of the gallbladder, with an optimum vision and exposition of the triangle of Calot. Newly designed and already existing instruments and devices are deployed inside the abdominal cavity and used to perform surgical procedures. Thereafter, they are removed together with the surgical specimen through a single umbilical incision. Because TCMR is only performed with a single 12-mm trocar, it results in no visible scars and provides a superlative cosmesis and inferior pain scores in comparison to classic laparoscopy and other transumbilical approaches. The internal magnetic device replaces the use of graspers, needles or sutures and supplies the necessary retraction/countertraction force to enable sufficient triangulation. An external, larger and more powerful magnet placed over the abdominal wall controls it. Moreover, since it is not fixed at any level it can freely cruise the abdominal cavity according to the surgeon’s need. Despite its few limitations and the need for further research, TCMR is a feasible and safe alternative to videosurgery and other transumbilical approaches. It is simple to learn and applicable in patients weighing more than 10 kg and a body mass index inferior to 40 kg/m2.
