Summary
Choosing the right reconstruction after proximal gastrectomy is key for reflux control and quality of life. Double-tract reconstruction (DTR) offers a good balance, while simple esophagogastrostomy (EG) shows poorer reflux control.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Clinical Outcomes Research
Background:
- Proximal gastrectomy preserves gastric function but reconstruction techniques impact reflux and quality of life (QOL).
- Comparative efficacy of reconstruction methods after proximal gastrectomy remains unclear.
Purpose of the Study:
- To systematically review and synthesize evidence on reflux control and QOL outcomes following different reconstruction techniques after proximal gastrectomy.
Main Methods:
- PRISMA-guided literature search of PubMed and Web of Science (2000-2025).
- Inclusion of adult gastric cancer cohorts with original clinical data reporting reflux or QOL.
- Narrative synthesis of data from 32 included studies (2958 patients).
Main Results:
- Simple esophagogastrostomy (EG) showed the poorest reflux control and highest stricture rates.
- Double-tract reconstruction (DTR) demonstrated a favorable balance of reflux control, low leakage, and acceptable stricture rates.
- Valve-forming techniques like double-flap showed low reflux but potential stricture risks; other methods had limited evidence.
Conclusions:
- Double-tract reconstruction (DTR) is a practical and broadly applicable option for proximal gastrectomy.
- The double-flap technique offers strong reflux control but carries a risk of anastomotic stricture.
- Further high-quality, multicenter studies are needed to definitively optimize reconstruction choices.
