Summary

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.

Study site: Daping Hospital, Army Medical Center, Chongqing, China Study duration: December 2025 to March 2027 Contact: For more information, please contact the research team at Daping hospital.

Interventions

PROCEDURE

Indocyanine green-guided omental shield anastomosis for cervical esophagogastric anastomosis

Step 1: ICG-guided gastric conduit prep: IV ICG fluorescence laparoscopy assesses gastroepiploic arcade (Koskas types) and perfusion zones (red=good, blue=poor), marks optimal anastomotic site on greater curvature, optimizes conduit tailoring. Step 2: T-Shaped Stapled Anastomosis\*\*: 1cm opening on posterior greater curvature wall at best perfusion zone, side-to-side stapling of posterior esophagus to greater curvature, closes common opening, reinforces with absorbable sutures. Step 3: Omental Shield: mobilizes pedicled omentum with good blood supply, 360° sleeve-wrap of anastomosis + 2cm area, fixes with 4-6 absorbable sutures to gastric wall above/below, ensures no tension/torsion.
