目的:总结人工智能(AI)人眼追踪4K高清裸眼三维腹腔镜在胃肠肿瘤根治术中应用体会。方法:回顾性分析上海交通大学附属第一人民医院2019年7月—2020年3月行AI人眼追踪4K高清裸眼三维腹腔镜胃肠肿瘤根治术的30例胃肠肿瘤患者的临床资料。30例中，男16例、女14例，年龄38～77岁；胃癌7例、结肠癌15例、直肠癌8例。观察和记录患者的手术时间、淋巴清扫数量、术中出血、术后排气时间、腹腔引流导管留置时间、住院时间等围术期指标，以及术后并发症等情况。结果:30例胃肠肿瘤患者均顺利完成手术，其中胃癌、结肠癌和直肠癌患者的手术时间分别为(142.6±28)、(390.9±20.5)、(117.4±27.1)min，淋巴清扫数量分别为(35.8±6.5)、(30.8±4.5)、(25.2±6.3)枚，术中出血分别为(105.8±33.3)、(55.8±25.6)、(85.7±28.6)mL，术后排气时间分别为(2.5±2.1)、(1.3±0.7)、(2.5±1.2)d，导管留置时间分别为(4.3±0.7)、(1.6±0.7)、(4.1±1.4)d，住院时间分别为(9.8±2.5)、(7.6±1.2)、(8.7±1.9)d。患者术后均未出现腹腔感染、出血、吻合口瘘以及淋巴瘘等相关并发症。结论:AI人眼追踪4K高清裸眼三维腹腔镜有助于术者更精准、更安全、更舒适地完成手术，适用于临床胃肠肿瘤外科治疗。“,”Objective:To determine the application potential of artificial intelligence (AI) eye-tracking 4K high-definition (HD) naked eye three-dimensional (3D) laparoscopy in radical gastrointestinal tumor surgery.Methods:The clinical data of 30 patients with gastrointestinal tumors who underwent AI eye-tracking 4K HD naked eye 3D laparoscopic radical gastrointestinal tumor resection from July 2019 to March 2020 in the the First People's Hospital Affiliated to Shanghai Jiao Tong University were retrospectively analyzed. The patients included 16 males and 14 females, aged 38-77 years old. Seven cases had gastric cancer, 15 cases had colon cancer, and 8 cases had rectal cancer. We observed and recorded the relevant indicators of patients during the perioperative period (patient's operation time, number of lymphatic dissections, intraoperative bleeding, postoperative exhaust time, indwelling time of abdominal drainage catheter, hospital stay) and postoperative complications.Results:The operation was successfully performed in all 30 patients. The operation times of patients with gastric cancer, colon cancer, and rectal cancer were (142.6±28), (390.9±20.5), and (117.4±27.1) min, respectively. The number of lymphatic dissections was (35.8±6.5), (30.8±4.5), and (25.2±6.3), respectively. The intraoperative bleeding was (105.8±33.3), (55.8±25.6), and (85.7±28.6) mL, respectively. The postoperative exhaust times were (2.5±2.1), (1.3±0.7), and (2.5±1.2) days, respectively. The indwelling times of abdominal drainage catheter were (4.3±0.7), (1.6±0.7), and (4.1±1.4) days, respectively. The hospital stay was (9.8±2.5), (7.6±1.2), and (8.7±1.9) days, respectively. All patients had no complications such as abdominal infection, bleeding, anastomotic leakage, and lymphatic fistula.Conclusions:AI eye-tracking 4K HD naked eye 3D laparoscopy helps the surgeon complete the operation more accurately, safely, and comfortably. Thus, it is suitable for clinical gastrointestinal tumor treatment.
