Background：Robotic surgery, particularly with the da Vinci Surgical System™, has advanced minimally invasive surgery, offering precision and improved outcomes. With the emergence of novel systems like Japan's hinotori™, approved in 2020, this study evaluates its application in colorectal surgeries.
Methods：A retrospective review was conducted on 93 patients who underwent colorectal surgery with the hinotori system from November 2022 to July 2024 at our institution. The study included 46 patients with rectal neoplasms and 47 with colon cancers. Data from a prospective colorectal database containing clinical and pathological information were analyzed.
Results：For the 46 rectal cancer patients, the median age was 64 years, with 26 males and 20 females. The median BMI was 22.3. Clinical stages were as follows：14 patients in stage I, 6 in stage II, 22 in stage III, and 4 in stage IV. Surgical procedures included anterior resection in 38 cases, intersphincteric resection in 3 cases, and abdominoperineal resection in 1 case, with lateral lymph node dissection performed in 2 cases. The median operative time was 265 minutes, and the median blood loss was 16 ml. Postoperative complications included 3 cases of ileus and 1 case of anastomotic leakage. For the 47 colon cancer patients, the median age was 72 years, with 27 males and 20 females. The median BMI was 23.1. Clinical stages were as follows：20 patients in stage I, 11 in stage II, 13 in stage III, and 3 in stage IV. Surgical procedures included ileocecal resection in 12 cases, right hemicolectomy in 11 cases, transverse colectomy in 1 case, left hemicolectomy in 9 cases, and sigmoidectomy in 14 cases. The median operative time was 233 minutes, and the median blood loss was 17 ml. Postoperative complications included 2 cases of ileus and 2 cases of surgical site infections.
Conclusions：The hinotori system demonstrates safety and feasibility in colorectal surgeries, with minimal blood loss and favorable short-term outcomes, supporting its potential in expanding the capabilities of robotic-assisted colorectal surgery.
