Abstract

Objectives: To evaluate certain technical characteristics of large gastric conduit reconstruction for esophageal replacement in the treatment of esophageal cancer. Methods: A cross-sectional descriptive study was conducted on 90 patients with esophageal cancer who underwent thoracoscopic esophagectomy with large gastric conduit reconstruction at Military Hospital 103 and 108 Central Military Hospital from January 2021 to July 2025. Results: The large gastric conduit had a mean width of 5.1 ± 0.2cm and a mean length of 31.9 ± 1.8cm. Conduit width was normally from 5 - 5.5cm (73.4%), and conduit length was 30 - 33cm (nearly 80%). Totally laparoscopic gastric conduit reconstruction accounted for 25.6%, laparoscopic-assisted procedures accounted for 65.6%, and open surgery accounted for 8.8%. Gastric conduit formation using open stapler and laparoscopic stapler techniques were 74.4% and 25.6%, respectively. No technical complications related to gastric conduit formation were observed. Respiratory complications occurred in 16.7%, anastomotic leak in 5.6%, chylothorax in 3.3%, and mortality in 2.2%. The mean postoperative hospital stay was 13.5 ± 7.8 days. Anastomotic leakage was significantly more common in patients with conduit width < 5 cm compared to those with width ≥ 5cm (p = 0.02). Conclusion: Thoracoscopic esophagectomy with large gastric conduit reconstruction is feasible, safe, and associated with a low anastomotic leak rate.
