Two-handed assisted laparoscopic surgery: Evaluation in an animal model

Abstract

ARTICLE INfO ______________________________________________________________ ______________________Purposes: To evaluate in an animal model the feasibility of a novel concept of hand--assisted surgery consisting of inserting two hands into the abdomen instead of one. The chosen procedure was retroperitoneal lymph node dissection (L-RPLND) that was performed in five pigs. Surgical Technique: A Pfannestiel and a transverse epigastric incisions were made through which both hands were introduced. The scope was inserted through the umbilicus. The colon was moved medially and the dissection was performed as in open surgery using short conventional surgical instruments. Comments: The surgery was fulfilled easily and safely in quite a similar way as in open surgery. Two-handed laparoscopy may be indicated in cases that still today require an open approach as apparently makes the operation easier and significantly shortens the surgery time. However, new opinions and trials are required.
