Patient’s description (time of onset, main symptoms, hospital visited, etc.): Male, 58 years old, a lung mass was detected on physical examination one month ago, with occasional chest tightness and shortness of breath for one year. CT showed peripheral lung cancer and enlarged mediastinal lymph nodes. He underwent right upper middle lung lobectomy + lymph node dissection 19 days ago and fasted for 3 days after surgery. Postoperative celiac disease, with volume ranging from 200-400 ml, was removed 9 days ago. Three days ago, the X-ray and chest ultrasound showed that the compression zone was visible around the right lung field, with about 10% compression, and the pleural effusion was 3cm, so the chest was drained by closed drainage. 600ml of celiac disease yesterday and 500ml of celiac disease today. Postoperative pathology showed: hypofractionated adenocarcinoma, 4*4*1.8cm in size, with metastasis in paratracheal, hilar and mediastinal lymph nodes. Pathology stage IIIA. Hospital: Celiac disease occurs from time to time after lung cancer surgery due to possible damage to lymphatic vessels by lymph node dissection.
