About this trial
This is a single-center, open-label, Phase Ib/II study aiming to assess the perioperative safety and postoperative outcomes of a novel surgical technique in treating primary adenocarcinoma located in the upper 1/3 of the stomach or gastroesophageal junction (Siewert II or III).
The study will enroll 30 patients who will undergo totally laparoscopic proximal gastrectomy with esophagogastrostomy by fissure technique. Clinical data will be collected to evaluate perioperative safety. Patients will be followed for at least 3 months, during which endoscopy will be performed to analyze occurrences and reasons for anastomotic-related complications. Additionally, the quality of life after surgery will be evaluated by QLQ-C30 and QLQ-STO22.
