Brief Summary

The aim of this study is to explore the advantages of robot-assisted thymectomy in long-term survival benefits and short-term clinical efficacy compared with video-assisted thoracoscopic thymectomy based on a multi-center, prospective, randomized controlled clinical trial.

Study Arms (2)

RATS for Thymectomy

EXPERIMENTAL

The operator of the surgical incision and the route of entry were determined, and the endoscope and surgical instruments were inserted through the operating hole. The phrenic nerve and diaphragm began to gradually separate upward while avoiding nerve damage. Subsequently, the innominate vein was dissected to observe the branches of the thymus vessels and clamped with a 5 mm Hem-o-Lok clamp. Continue to dissect the left side of the thymus until near the phrenic nerve. After the thymus was removed entirely, it was placed in a bag and removed through an incision. After the operation, a 28 Fr chest tube was placed through the incision to the chest top. An 18 G central venous catheter was placed at the level of the posterior axillary line to the posterior costophrenic angle, and about 10 cm was inserted.

Procedure: RATS for Thymectomy

VATS for Thymectomy

ACTIVE COMPARATOR

The main operation principles and procedures of the operation are basically similar to those of the RATS and are completed under video-assisted thoracoscopic surgery.

Procedure: VATS for Thymectomy
