To explore a surgical approach for handling the gastrocolic trunk, referred to as "isolated anatomical dissection of the gastrocolic trunk" and evaluate its safety and efficacy.

This study retrospectively analyzed the clinical data of 25 patients who underwent this technique in the Gastrointestinal Tumor Center of Guangdong Provincial Hospital of Traditional Chinese Medicine from June to December 2023, parameters examined included gastrocolic trunk type, operation time, intraoperative blood loss, gastrocolic trunk exposure time, postoperative complications, postoperative hospital stay, etc.

The mean time to isolate the gastrocolic trunk was (9.5±1.6) min, and the overall mean operative time was (88.1±11.1) min. The estimated bleeding volume at the time of isolation of the gastrocolic trunk was 3.1 (0.5, 8.5)mL, of which 3 cases were greater than 10 mL, of which one case was 12 mL, one case was 13 mL, and one case was 18 mL. The postoperative length of hospital stay was (5±1.5) days, and the mean number of lymph nodes cleared was 22.5±4.5. There were no postoperative complications in any of the 25 cases, and there were no cases of readmission within 30 days.

"Isolated dissection of the gastrocolic Trunk" is a new surgical technique for laparoscopic right hemicolectomy, which is worth further verification and promotion.
