Abstract:
Objective:To evaluate the safety and feasibility of Da Vinci robot-assisted proximal gastrectomy (PG) for proximal gastric cancer (PGC) and adenocarcinoma of the esophagogastric junction (AEG).Method:Twenty-five patients (PGC: n=7; AEG: n=18) undergoing Da Vinci-assisted PG at the First Affiliated Hospital of Dalian Medical University from Jan 2021 to Mar 2025 were divided into (indocyanine green ,ICG) ( n=9) and non-ICG ( n=16) groups based on whether intraoperative ICG navigation was used. Perioperative outcomes and pathological data were compared. Results:All operations were successfully completed without conversion to open surgery. The median proximal resection margin was 3.0 cm (2.5-3.0) cm, and the median distal resection margin was 4.0 cm (3.0-5.0) cm. Operative time in the ICG and non-ICG groups was (294.4±41.3) min and (354.4±67.4) min, respectively, with a statistically significant difference ( t=2.760， P< 0.05). The total number of lymph nodes harvested, as well as D 1 and D 2 LN stations, was (29.3±14.8) vs. (21.8±6.3), 17.0 (10.0-24.8) vs. 14.0 (11.0-22.5), and 10.0 (2.0-17.0) vs. 7.2 (2.0-7.5) in the ICG and non-ICG groups, respectively. Although the ICG group showed a trend toward higher LN yield, the difference was not statistically significant ( P>0.05). Conclusions:Da Vinci robotic assisted proximal gastrectomy is safe and feasible for treating PGC and AEG. ICG fluorescence imaging demonstrates promising clinical value.
