Abstract: Objective To explore the feasibility and safety of concealing incision video-assisted thoracoscopic surgery (VATS). Methods We retrospectively analyzed the clinical data of 11 patients who underwent concealing incision VATS in West China Hospital of Sichuan University between September and November 2011. There were 2 male patients and 9 female patients with their mean age of 34.0 years (ranging from 16 to 59 years). There were 4 patients with myasthenia gravis, 4 patients with thymoma, 2 patients with thymus cyst, and 1 patient with hyperhidrosis. Extended thoracoscopic thymectomy was performed in 10 patients, and endoscopic thoracic sympathectomy was performed in 1 patient. Results All the VATS procedures were performed successfully, and there was no intraoperative and postoperative complication. The operation time ranged from 30 to 105 minutes with an average time of 70.5 minutes. All the intraoperative blood loss was less than 5 ml. The time of postoperative thoracic drainage was less than 48 hours, and the drainage volume ranged from 30 to 80 ml with a mean volume of 55.5 ml. The mean postoperative hospital stay was 3.5 (2-4)days. The incision was small with a concealed and esthetic appearance. For 10 patients with extended thoracopscopic thymectomy, histopathology test aftre operation showed 4 patients with thymic hyperplasia, 4 with thymoma, and 2 with cystofthymus. Conclusion Concealing incision VATS is a safe and feasible technique, and it can meet the esthetic requirement of patients.
