%X <B>BACKGROUND: </B>Robotic distal gastrectomy (RDG) with Billroth I (BI) reconstruction is predominantly performed due to its physiological congruence and simplicity. The Intracorporeal Triangular Anastomotic Technique (INTACT) aims to reduce ischemic areas compared to the conventional Delta-shaped anastomosis using the unique characteristics of robotic surgery to standardize procedures, thereby ensuring safe, simple, and reliable reconstruction. This study aims to investigate the efficacy of the INTACT in RDG with BI reconstruction, focusing on its robotic precision in minimizing ischemic zones and improving surgical reliability.<BR><B>METHODS: </B>The posterior duodenal wall is dissected before reconstruction, and the hepatoduodenal ligament is severed to facilitate passive duodenal manipulation. A quarter-circumference incision is created centrally on the anterior wall of the duodenal stump to avoid excessive tension during anastomosis and to ensure an adequate anastomotic diameter. A small opening is established on the greater curvature of the remaining stomach, and the posterior walls of the stomach and duodenum are joined using a Linear stapler in the first fire. A V-shape is created, and two EndoWrist instruments (robotic first and fourth arms) are utilized to grip and extend the anastomosis diameter, completing the anastomosis with a shared hole closure using the Linear stapler. The robotic arms' features improve the physiological integrity and stability of the BI reconstruction.<BR><B>RESULTS: </B>A total of 81 patients underwent RDG with INTACT from September 2020 to January 2024. The median age was 72 years (range: 31-91), with 49 males and 32 females. The median blood loss was 0 ml (range: 0-200 ml), and the median postoperative hospital stay was 8 days (range: 6-20 days). No cases required reanastomosis during surgery, and no postoperative anastomotic leakage, surgery-related reoperations, or anastomotic strictures were reported.<BR><B>CONCLUSIONS: </B>INTACT in RDG can be safely performed. The characteristics of the EndoWrist instruments helped in stabilizing the technique, making it a viable option in robotic-assisted surgeries.
