Background/aim: The optimal reconstruction method for laparoscopic proximal gastrectomy (LPG) remains controversial. The present study aimed to compare short-term outcomes, including assessment of nutritional parameters and skeletal muscle, between two different methods, double-tract reconstruction (DTR) versus esophagogastrostomy (EG).
Patients and methods: Data from patients who underwent LPG for gastric tumor(s) between 2018 and 2021, were retrospectively analyzed. Patients were divided into two group: DTR (n=11) and EG (n=17). Since 2020, the authors have applied the modified side overlap with fundoplication by Yamashita (mSOFY) method as the EG technique.
Results: Compared with DTR, EG was associated with a shorter reconstruction time (p=0.003). Complications of grade ≥3 occurred only in the EG group [n=4 (23.5%)] and the incidence of abnormal endoscopic findings after surgery was numerically higher in the EG group (n=2 vs. n=9; p=0.047). Across virtually all data points on the line graph, the EG group exhibited greater changes in post-discharge nutritional parameters, with Skeletal Muscle Index also demonstrating significant superiority (0.83 vs. 0.89; p=0.045).
Conclusion: Among reconstruction methods for LPG, EG demonstrated superiority over DTR in preserving nutritional parameters and skeletal muscle mass. However, further research, including larger cohorts and longer-term follow-up, is necessary to validate this finding.
