Brief Summary Study title: Indocyanine green (ICG)-guided omental shield anastomosis (ICG-OSA) technique for cervical esophagogastric anastomosis in esophageal cancer surgery Purpose: To evaluate whether a novel surgical technique can reduce the risk of anastomotic leakage after minimally invasive esophageal cancer surgery.
Eligible participants: Adults aged 18-80 years with histologically confirmed esophageal squamous cell carcinoma (ESCC) in the middle or lower thoracic esophagus who are scheduled for esophagectomy.
The technique: All participants will undergo the ICG-OSA procedure, which uses indocyanine green fluorescence imaging to assess gastric perfusion, creates a T-shaped esophagogastric anastomosis, and wraps the anastomosis with a pedicled omental flap.
Outcome assessments: The primary outcome is anastomotic leakage rate within 30 days after surgery. Secondary assessments include surgical site infection, anastomotic stricture, and hospitalization costs.
