Short-term results of robot-assisted colorectal cancer surgery using Senhance Digital Laparoscopy System
ASIAN JOURNAL OF ENDOSCOPIC SURGERY(2022)
Abstract
Background: The Senhance Digital Laparoscopy System (Asensus Surgical Inc, Morrisville, NC, United States), which was introduced for the first time in Japan by our hospital, is a new surgical assistive robot following the da Vinci Surgical System. We herein report the short-term outcomes of 55 colorectal cancer surgery cases using this system at our hospital to assess the feasibility and safety of our procedures. Materials and Methods: We retrospectively reviewed the patient backgrounds and surgical outcomes of 55 patients who underwent Senhance-assisted laparoscopic colorectal cancer surgery. Results: The median age was 71 years. There were 31 males and 24 females, and the median body mass index was 23.1 kg/m(2). Fifteen patients had a history of abdominal surgery. The most common surgical technique was ileocecal resection (18 cases, 32.7%), followed by high anterior resection (11 cases, 20.0%). D2 or D3 dissection was performed in each operation, and D3 dissection was performed in 41 cases (74.5%). The median operative time was 240 minutes, the median blood loss was 5 mL, there were no intraoperative complications, and there were no cases of intraoperative blood transfusion. The median postoperative hospital stay was 7 days, which was comparable to conventional laparoscopic surgery. Postoperative complications of grade 2 or higher in the Clavien-Dindo classification were observed in two cases. Conclusion: The short-term results of 55 colorectal cancer surgery cases using the Senhance Digital Laparoscopy System were excellent and the system was introduced and surgery was safely performed.
