Early experience with a new integrated microwave surgical device, Acrosurg Revo®, for laparoscopic surgery: A case series of two patients.

ABSTRACT

INTRODUCTION: Abdominal surgery uses various energy devices for vessel sealing, tissue dissection, and detachment. Currently, Acrosurg Revo® (Nikkiso Co., Ltd., Tokyo, Japan), a novel energy device using microwaves, has been developed for use in laparoscopic surgery. This report describes the early clinical experience of using this device in two cases of laparoscopic surgery. PRESENTATION OF CASE Case 1 was of a 64-year-old woman who underwent laparoscopic abdominal incisional hernia repair. Case 2 was of a 56-year-old man with a diagnosis of ascending and sigmoid colon cancer who underwent laparoscopic right hemicolectomy and sigmoid colectomy with D3 dissection. Each surgery was completed using Acrosurg Revo® and an endoscopic electrosurgical unit. The postoperative course was uneventful, and both patients were discharged from the hospital without any complications. DISCUSSION: With this new and novel device, vessel sealing, hemostasis, coagulation, tissue dissection, and detachment were all possible. Notably, there was no spark or mist that hindered the surgical field of view. Furthermore, because microwave coagulation did not result in tissue carbonization, there was a considerable decrease in device tip contamination. CONCLUSION: The Acrosurg Revo® may be a useful energy device for laparoscopic surgery.
