Transthoracic versus Transhiatal Esophagectomy for Esophageal Squamous Cell Carcinoma.
Esophageal squamous cell carcinoma (ESCC) is associated with high morbidity and mortality, and esophagectomy remains the mainstay of curative treatment. The optimal surgical technique transthoracic esophagectomy (TTE) versus transhiatal esophagectomy (THE) continues to be debated due to differences in surgical invasiveness and the extent of lymphadenectomy. This study aimed to compare clinical and oncological outcomes of TTE and THE in patients treated for ESCC.
This retrospective study included patients who underwent curative-intent esophagectomy for histologically confirmed ESCC between 2015 and 2023. Patients were categorized according to surgical approach (TTE vs THE), and demographic characteristics, perioperative data, pathological findings, postoperative complications, and survival outcomes were compared between the 2 groups. Complications were classified according to the Clavien-Dindo system. Disease-free survival (DFS) and overall survival (OS) were assessed using Kaplan-Meier analysis.
A total of 39 patients were analyzed (21 TTE, 18 THE). Baseline demographic features and most perioperative variables were comparable. TTE was associated with a significantly longer operative time and higher lymph node yield, whereas THE showed higher rates of intraoperative transfusion and pleural effusion. Other postoperative complications were similar between groups. The TTE approach demonstrated significantly better DFS (P = .004). No significant difference in OS was observed between the groups (P = .165). No additional clinical or pathological factors were associated with survival outcomes.
TTE resulted in a greater lymph node yield and significantly improved DFS, indicating a clear oncologic advantage over the transhiatal approach.
