Association Between Thoracic Inlet Size and Cervical Anastomosis Outcomes in Esophageal Cancer Surgery

Area of Science:

• Thoracic surgery
• Surgical oncology
• Medical imaging

Background:

• Esophageal cancer surgery carries significant risks, including high morbidity and mortality.
• Anastomotic leakage (AL) is a major complication affecting patient outcomes.
• The influence of thoracic inlet size on posterior mediastinal reconstruction outcomes is not well understood.

Purpose of the Study:

• To investigate the association between thoracic inlet geometry and postoperative outcomes in patients undergoing esophagectomy with posterior mediastinal reconstruction.

Main Methods:

• Retrospective analysis of 67 patients who underwent esophagectomy.
• Preoperative computed tomography (CT) scans were used to measure thoracic inlet area (TIA).
• Correlation of TIA with postoperative complications, anastomotic leakage, and mortality.

Main Results:

• Postoperative complications occurred in 29.9% of patients, with anastomotic leakage in 14.9% and 30-day mortality in 13.4%.
• Non-survivors had a significantly lower thoracic inlet area (513.5 mm² vs. 703.3 mm², p=0.012).
• Anastomotic leakage was more frequent in non-survivors (66.7% vs. 6.9%).

Conclusions:

• Thoracic inlet geometry, specifically a smaller thoracic inlet area, may be associated with adverse postoperative outcomes, including mortality and anastomotic leakage, in posterior mediastinal reconstruction.
• These findings suggest a potential role for thoracic inlet measurements in risk stratification.
• Larger prospective studies are needed to confirm these associations and guide clinical practice.
