 The usefulness of robotic gastrectomy and the benefit of left-handed laparoscopic coagulation shears technique

Department of Surgery, Tokushima University
【Background/Aims】
The purpose of this study is to examine the usefulness of the robotic gastrectomy (RG) compared with laparoscopic gastrectomy (LG) and to investigate the benefit of left-handed laparoscopic coagulation shears (LCS) technique.
【Patients and methods】
Seventy-four patients were operated on using robotic surgery in our department. Operative procedures were TG:25, DG:43, PG:3 and PPG:3. The lymph node dissection was performed D1:2, D1+:43, D2:29. Operating time, anastomosis time, and post-operative complications were compared.
【Result】
1. Comparison RG with LG
Compared with the lap group, robotic surgery takes a long time（323min vs 301min p<0.05）, on the other hand, in concerning the console time, robot takes a shorter time （233min vs 301min p<0.05）. But no difference was noted in terms of intraoperative bleeding (22ml vs 31ml p=0.53), and there was no significant difference on observed complications.
2. The usefulness of left-handed approach
In 63 patients, we performed left- handed LCS technique. Operative time:334min, console time: 235min, Blood loss: 30ml. morbidity (Clavien dindo 3≦) 1.5%. The benefits of left-handed approach were 1 : same image as lap-surgery, 2: Adjusted axis of surgical devices 3:Dissection by right hand meryland. In D2 LN dissection, 12a, 11p and 11d were dissected from the left side.
【Conclusion】
RG was performed safely performed and left-handed LCS technique is useful in RG.
