Celiac leakage is lymphatic fluid that leaks from ruptured lymphatic vessels close to the celiac pool, which is milky-white in color, while lymphatic leakage is lymphatic fluid that leaks from ruptured lymphatic vessels away from the celiac pool, which is clearer in color. Celiac leakage is mainly characterized by the milky white color of the postoperative drainage fluid, which appears after the patient has eaten. However, if the patient eats a meal that is low in fats and oils, the celiac fluid becomes clearer in color and is not easy to distinguish, at which point it can also be referred to as a lymphatic leak. Celiac leakage is the lymphatic fluid leaking out of the broken thoracic duct; lymphatic leakage is the lymphatic fluid leaking out of the broken common lymphatic duct. Celiac fluid and lymphatic fluid are similar in composition, both containing celiac particles, fats, proteins, electrolytes and other substances. The main difference between celiac disease and lymphatic leakage is the higher triglyceride content in celiac disease. Celiac leakage or lymphatic leakage generally occurs as a result of intraoperative injury to the lymphatic vessels and is a common complication of lymphatic cleansing. In some areas after surgery, if celiac fluid accumulates and is not treated in time, it can cause localized flap floating or even necrosis, and in severe cases, it can cause life-threatening hemorrhage.
