Impact of an individualized camera port position adjustment on short-term outcomes in robotic gastrectomy

The robotic approach improves the safety and effectiveness of gastric cancer surgery; however, it increases operative time. This study evaluated the effect of individualized adjustment of camera port positioning on short-term outcomes of robotic gastrectomy (RG).

This study included consecutive patients who underwent RG for gastric cancer at our department between August 2019 and April 2025. Short-term outcomes were compared between RG with adjustment for camera port positioning at the height of the angle of Treitz using computed tomography images (A group, n = 30) and those without adjustment (NA group, n = 89).

No significant differences were observed in patient characteristics between the groups; however, both operative and console times were significantly shorter in group A (both P < 0.001). The estimated blood loss and duration of postoperative stay were also lower in Group A, whereas the incidence of postoperative morbidity was similar. In a multivariate analysis, adjustment of the camera port was identified as an independent predictor of shortened operative time (odds ratio 0.039, P < 0.001).

Individualized adjustment of camera port positioning could be useful for improving the short-term outcomes of RG, including reduction in operative time.
