About

Ruochuan Sun is a pioneering gastrointestinal surgeon whose research focuses on advancing minimally invasive techniques for gastric cancer surgery, particularly through robotic and laparoscopic approaches. His major contributions center on developing novel methods for esophagojejunostomy and reconstruction after gastrectomy, with the goal of improving patient outcomes and surgical precision. Sun’s most cited work, “Robotic total gastrectomy with π-shaped esophagojejunostomy using a linear stapler as a novel technique” (2018, 13 citations), introduces an innovative intracorporeal anastomosis technique using the Da Vinci robotic system, demonstrating its feasibility and safety for D2 total gastrectomy. This work has been influential in refining robotic surgical protocols. He further expanded this concept in a 2021 study (3 citations) proposing a π-shaped esophagojejunostomy combined with double-tract reconstruction for proximal gastrectomy in early gastric cancer, offering an alternative to traditional methods. Sun’s research is notable for its practical, technique-driven focus, directly impacting surgical practice in oncology. His achievements highlight his role in pushing the boundaries of robotic surgery, making complex procedures more accessible and effective for patients with gastric malignancies.
