Objective:

To describe the biologic flap technique (BFT) for laparoscopic proximal gastrectomy and assess its short-term outcomes compared with the double-flap technique (DFT).

Approach:

• Design and setting: Retrospective review of consecutive patients treated from January 2020 through June 2024 at one hospital.
• Eligibility: Included patients with histologically confirmed gastric adenocarcinoma who underwent laparoscopic proximal gastrectomy with BFT or DFT and achieved R0 resection. Patients receiving neoadjuvant therapy, emergency surgery, or treatment for another malignancy wer…
• Procedures: BFT uses a porcine small-intestinal-submucosa patch around a mechanical esophagogastric anastomosis; DFT was the comparator. Operations were performed by surgeons with more than 15 years of laparoscopic gastric cancer experience.

Key Findings:

• The supplied article context describes the study rationale, eligibility criteria, and surgical methods but does not provide comparative short-term outcome results.

Interpretation:

The context presents BFT as a proposed mechanical anti-reflux reconstruction and outlines a retrospective comparison with DFT; it does not report findings that establish comparative effectiveness or safety.

Limitations:

• The study is retrospective and conducted at a single center.
• BFT was introduced in April 2023, so the comparison may involve different treatment periods.
• The provided context does not include sample size, outcome data, or statistical analyses.

Conclusion:

The supplied material is insufficient to summarize the study’s short-term comparative outcomes.
