An innovative bipolar instrument for laparoscopic surgery.

OBJECTIVE: Bipolar electrosurgery is an excellent method for obtaining hemostasis at laparoscopy. The present study describes and evaluates a bipolar device that can be more versatile and cost effective in advanced operative procedures than the traditional instrumentation. METHODS: This was a retrospective, case-controlled analysis of bipolar instrumentation with a design classification of II-2. A single surgeon in a private practice setting performed all procedures. Sixteen patients, matched for age and pathology were evaluated by videotape review to determine the comparative efficiency of the BiCOAG bipolar dissector/grasper versus traditional Kleppinger bipolar forceps. Efficiency here is defined as comparative operating times in each group. RESULTS: The number of instrument changes per case was counted because this appeared to be the only variable other than time that differentiated the 2 groups. The BiCOAG bipolar dissector/grasper device group had 4 times fewer instrument changes and significantly decreased operating room times when compared with that of the Kleppinger forceps group. Because cost per unit of operating room time was a constant figure, the decrease in cost that resulted due to the decrease in operating time is considered a cost-effective measure. CONCLUSIONS: The BiCOAG bipolar dissector/grasper is a cost-effective, efficient instrument for use in operative laparoscopic procedures.
