Exploring the Potential of Robotic Single-Port Surgery for Gallbladder Cancer: Initial Insights and Future Prospects.

Background: Robotic surgery has demonstrated outcomes comparable or superior to open and laparoscopic surgeries for extended cholecystectomy.1, 2, 3, 4, 5, 6, 7–8 Despite its advantages, the minimally invasive robotic single-port (SP) system remains underutilized in complex hepatobiliary pancreatic surgery due to instrument limitations and retraction issues.9,10 This study evaluated the feasibility, safety, and effectiveness of the da Vinci SP system in gallbladder cancer surgery. The study was approved by the Ethics Committee of OOO University Hospital (IRB no. DAUH IRB-24-081) and conducted in accordance with the principles of the Declaration of Helsinki. The requirement for informed consent was waived due to the study's retrospective design. Methods: A 62-year-old woman with a diagnosis of gallbladder cancer was referred for surgery. Preoperative computed tomography (CT) scans showed no evidence of metastasis (T2N0). Therefore, a robotic SP extended cholecystectomy was planned. Figure 1 shows a 30-mm SP port and a 1-mm assistant port inserted for the procedure. Due to the absence of an energy device for the liver wedge resection, Maryland bipolar forceps were used, mimicking the Kelly clamp crushing technique. A monopolar cautery hook was used for lymph node resection of stations 7, 8, 12, and 13 (Fig. 2). Results: The total duration of the operation was 226 min, with an estimated blood loss of 200 ml. The CT scan on day 5 showed no abnormalities, and the patient was discharged routinely on day 7 (Fig. 3). The pathologic examination confirmed adenocarcinoma (T2a) with clear resection, and all six lymph nodes tested negative for malignancy. Conclusions: This study underscores the adequacy of robotic surgeries and emphasizes the potential of the da Vinci SP system in hepatobiliary surgery. Despite current challenges related to instrument limitations, the authors are confident that the SP system will evolve into a crucial asset for hepatobiliary surgical practices in the foreseeable future.
