Robotic Full-Thickness Resection of a Type IV Gastric Gastrointestinal Stromal Tumor (GIST) Through Organoaxial Gastric Rotation: Technical Description With Video and Operative Management Insights

Gastrointestinal stromal tumors (GISTs) of the stomach are increasingly managed using minimally invasive approaches. Tumors located on the posterior gastric wall (type IV) pose significant challenges due to limited exposure and difficult angulation. Robotic surgery may offer technical advantages in such anatomically complex cases. We describe a case of robotic full-thickness resection of a posterior wall gastric GIST using organoaxial gastric rotation to optimize exposure. In type IV gastric GIST, organoaxial gastric rotation plays a pivotal role, facilitating the exposure of posterior lesions without anterior gastrotomy or excessive mobilization. Robotic surgery ensures stable operative field exposure and precise dissection and suturing in anatomically challenging regions.
