Beskrivelse
Inclusion Criteria:
- Age between 18 and 75 years inclusive.
ECOG performance status ≤ 2.
Histologically confirmed proximal gastric cancer or Siewert type II adenocarcinoma of the esophagogastric junction.
Clinical stage cT1-T3, N0-N+, M0.
Tumor maximum diameter ≤ 4 cm and esophageal invasion ≤ 2 cm.
Candidates for radical proximal gastrectomy (PG) with feasibility of R0 resection and functional anastomosis.
Assessed by a Multidisciplinary Team (MDT) as suitable for PG rather than total gastrectomy, with no requirement for neoadjuvant therapy.
Radiographic evidence of localized disease (no distant metastasis to liver, lung, or peritoneum via enhanced CT or MRI).
ASA physical status classification ≤ III.
Adequate bone marrow, hepatic, renal, cardiac, and pulmonary function.
Ability to understand and provide written informed consent.
Willingness and ability to comply with the 12-month postoperative follow-up schedule.
Exclusion Criteria:
- Clinical stage T4 or presence of distant metastasis.
Esophageal invasion exceeding 2 cm.
History of previous major gastric surgery (e.g., partial or total gastrectomy).
Other malignant tumors within the last 5 years.
Severe organic diseases that preclude safe anesthesia or surgery (e.g., severe heart failure, pulmonary fibrosis).
Requirement for emergency surgery due to active gastric bleeding, perforation, or acute obstruction.
Pregnant or lactating women.
Serious psychiatric disorders or cognitive impairment that interferes with study compliance.
Any other condition that, in the opinion of the investigator, would make the participant unsuitable for the study.

Eksperimentel: Single-Port Group
Participants in this group will undergo radical proximal gastrectomy utilizing the SP1000 single-port surgical platform.
The procedure focuses on performing the main surgical maneuvers through a centralized access point to evaluate the safety and clinical performance of the robotic system.
|
An investigational robotic-assisted surgical platform designed for single-port access.
In this study, the system is utilized to perform radical proximal gastrectomy.
The core surgical procedures are conducted through a centralized access point to assess the intraoperative safety and short-term clinical outcomes of this robotic-assisted approach.
|
|
Aktiv komparator: Traditional Laparoscopy Group
|
Standard multi-port laparoscopic radical proximal gastrectomy performed as a clinical control.
This procedure follows conventional laparoscopic techniques involving multiple abdominal incisions for the placement of surgical instruments and camera to treat proximal gastric cancer.

Tidsramme |
|---|---|---|
|
Incidence of Total Postoperative Complications (Clavien-Dindo Grade ≥ II)
Tidsramme: Within 30 days postoperatively.
|
The proportion of participants experiencing at least one postoperative complication graded II or higher according to the Clavien-Dindo Classification.
This includes surgery-related, systemic, and anesthesia-related complications.
If a patient experiences multiple complications, only the most severe grade will be used for statistical analysis.
