BACKGROUND: Pharyngolaryngectomy with total esophagectomy (PLTE) is often indicated for patients with synchronous head and neck cancer and thoracic esophageal cancer or those with head and neck cancer extending to the upper mediastinum. A long conduit is required for the reconstruction, and the blood flow at the tip of the conduit is not always sufficient. Thus, reconstructive surgery after PLTE remains challenging, and optimal reconstruction methods have not been elucidated to date. METHODS: This analysis investigated 65 patients who underwent PLTE. The short-term outcomes among the procedures were compared to explore the optimal digestive reconstruction methods. RESULTS: We used a simple gastric conduit for 7 patients, a gastric conduit with microvascular anastomosis (MVA) for 10 patients, an elongated gastric conduit with an MVA for 20 patients, a gastric conduit combined with a free jejunum transfer (FJT) for 25 patients, and other procedures for 3 patients. Postoperatively, 17 (26.2%) of the patients experienced severe complications, classified as Clavien-Dindo grade 3b or higher, including graft failure for 3 patients (6.2%). Anastomotic leakage was found in six patients (9.2%), and all leakages occurred at the pharyngogastric anastomosis. The reoperation rate was 15.4% (n = 10), and three patients (4.6%) died of massive bleeding from major vessels. The patients who underwent simple gastric conduit more frequently had graft failure (P = 0.04), anastomotic leakage (P < 0.01), and reoperation (P = 0.04) than the patients treated with the other reconstructive methods. CONCLUSION: Additional procedures such as MVA, gastric tube elongation, and FJT contribute to improving the outcomes of reconstruction after PLTE.
