Abstract:

Objective

To summarize the application experience of robotic resection of hepatic hemangioma and evaluate the safety of the surgery.

Methods

The clinical and pathological data of patients who underwent robotic resection of hepatic hemangioma from Aug. 2016 to Dec. 2024 was retrospectively analyzed. Patients were divided into <10 cm and ≥10 cm groups based on tumor size, and further divided into single and multiple groups based on the number of hemangioma. Da Vinci robot combined with intraoperative ultrasound were used to complete the hepatic hemangioma resection surgery.

Results

Among the 129 patients, there were 33 males and 96 females with an average age of 48 years. The average diameter of hemangioma was 8.6±2.4 cm, with 91 cases in the <10 cm group and 38 cases in the ≥10 cm group and 94 cases in the single lesion group and 35 cases in the multiple lesion group. Robotic resection surgery was completed in all the patients, and there were no patients who were converted to open surgery. The average surgical time was 97 (79.5-135.0) min, with an average intraoperative blood loss of 50 (20-100) ml.There were 8 cases of intraoperative blood transfusion, 2 cases of postoperative bile leakage, and an average hospital stay of 5 days. There were statistically significant differences (P<0.05) in the average surgical time, number of hepatic portal blockades, average intraoperative bleeding, and average postoperative hospital stay among patients with different tumor sizes. There were also statistically significant differences (P<0.05)in the average surgical time, number of hepatic portal blockades, and average intraoperative bleeding among patients with different tumor arrays.

Conclusions

The application of robotic resection of hepatic hemangioma, especially those located in complex areas, is safe and effective.
