Minimally Invasive Transhiatal Esophagectomy Using Antegrade Inversion Technique in Esophageal Cancer: 10-Year Experience from a Tertiary Care Center.

Abstract

Background: Esophageal cancer surgery aims for curative intent but carries high complication rates. Transthoracic esophagectomy is the dominant approach, however, transhiatal esophagectomy (THE) offers selective advantages in certain clinical scenarios. Minimally invasive THE (MI-THE) is an evolving technique with limited data. Methods: This retrospective study reviewed 38 patients with esophageal cancer who underwent MI-THE using "Antegrade Inversion Technique" between 2013 and 2023 at a tertiary care center. Perioperative outcomes were analyzed. Data were presented as mean with standard deviation, median with interquartile range, and percentages. Results: Most patients (86.8%) had early-stage cancer. Median operative time was 375 minutes, hospital stay was 8 days, and intensive care unit stay was 3 days. All patients achieved a negative resection margin. Pleural effusion (57.9%) was the most common complication, followed by pneumothorax (31.6%) and surgical site infection (15.8%). Anastomotic leak rate was 13.2%. There was no mortality. Conclusions: MI-THE appears safe and feasible with encouraging perioperative outcomes, particularly for early-stage disease and high-risk patients. While potentially offering advantages over open THE, further research is needed to definitively establish its role compared to traditional approaches.
