Abstract

Objective: This study aimed to evaluate the effectiveness and safety of autologous blood injection for tumor localization in laparoscopic gastric surgery. Participants and

Methods: A retrospective descriptive study was conducted on 27 patients who underwent preoperative endoscopic autologous blood injection prior to laparoscopic gastric surgery at Bach Mai Hospital from January 2024 to December 2024.

Results: The mean age was 63.5 ± 9.8 years, with a male-to-female ratio of 2.4. Gastric cancer stages T1–T2 accounted for 96.3% (26/27 patients), while post–early gastric cancer resection lesions accounted for 3.7% (1/27 patient). Tumors were most commonly located in the lower third of the stomach (74.1%, 20/27 patients), followed by the middle third (22.2%, 6/27 patients) and the upper third (3.7%, 1/27 patient). The mean interval between marking and surgery was 20.5 hours. The tattooed site was identified intraoperatively in 92.6% of patients (25/27), while it was not identified in 7.4% (2/27). The mean proximal resection margin distance was 5.3 ± 0.7 cm for tumors in the lower third of the stomach and 4.5 ± 0.5 cm for tumors in the middle third. No patients experienced complications related to endoscopic marking, such as perforation, peritonitis, intra-abdominal abscess, or bowel adhesions.

Conclusion: Preoperative autologous blood injection for tumor localization in laparoscopic gastric surgery is an effective and safe technique.
