Indocyanine Green-guided Omental Shield Anastomosis for Cervical Esophagogastric Anastomosis in Minimally Invasive McKeown Esophagectomy

Starting soon · Phase 2

Conditions studied: Esophageal Squamous Cell Carcinoma (ESCC), Esophageal Cancer

In brief

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.

Who can join

Age: 18 and older, up to 80. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

Age 18 to 80 years, of both sexes;
Pathological diagnosis: Histologically confirmed esophageal squamous cell carcinoma (ESCC) by biopsy;
Clinical staging: Preoperative clinical stage cT1-4aN0-3M0 (according to the 8th edition AJCC staging criteria), evaluated by the thoracic surgery team as eligible for radical McKeown esophagectomy;
Performance status ECOG 0-1；
Major organ function (cardiovascular, respiratory, digestive, hematological systems) assessed as having no contraindications for chemotherapy or immunotherapy, and no surgical contraindications;
Able to understand and comply with study protocol requirements, and willing to accept and undergo standardized postoperative follow-up;
Able to understand and sign the informed consent form.

You may not qualify if…

Allergy history: History of allergy to indocyanine green (ICG), iodide, or iodinated contrast agents (ICG contains iodine, and allergy may cause severe anaphylactic reactions);
Severe hepatic or renal dysfunction: Severe hepatic insufficiency (Child-Pugh Class C) or severe renal insufficiency (eGFR <30 mL/min/1.73 m²), affecting ICG metabolism and excretion;
Unfavorable tumor location: Tumor located in the cervical or upper thoracic esophagus (<25 cm from the incisors), making it difficult to ensure negative proximal resection margin;
Previous surgery history: Prior history of esophageal, gastric, or mediastinal surgery resulting in altered anatomy or severe adhesions;
Multiple primary cancers: Concurrent active malignant tumors in other sites (except cured basal cell carcinoma of the skin or cervical carcinoma in situ);
Special physiological status: Pregnant or lactating women, or those with planned pregnancy during the study period who are unwilling to use effective contraception;
Cognitive and behavioral issues: Presence of severe psychiatric illness, cognitive impairment, or history of substance abuse that would preclude compliance with study procedures;
Participation in other studies: Currently enrolled in other interventional clinical trials that may interfere with the results of this study;
Investigator judgment: Investigator considers the patient unsuitable for this clinical study (e.g., intraoperative exploration reveals severe tumor invasion of major structures such as the aorta or trachea, making R0 resection unachievable).
