NCT01768104

Brief Summary

The purpose of this study is to determine the efficacy and safety of endoscopic submucosal tunnel dissection (ESTD) compared with video-assisted thoracoscopic surgery (VATS) in the treatment of upper gastrointestinal submucosal tumors.

Outcome Measures

Primary Outcomes (1)

  • En bloc resection

    The En bloc resection was defined as a one-piece resection of the entire lesion without fragmentation

    During the operation

Secondary Outcomes (5)

  • Curative resection

    From date of randomization until the date of pathological diagnosis, an expected average of 7 days

  • Procedure related complication

    From date of operation until the occurrence of the procedure related complication, which most occur within 7 days after operation, assessed up to 2 years

  • Short-term morbidity

    From date of randomization until the date of death from any cause, assessed up to 3 months

  • Local recurrence

    From date of randomization until the follow-up ended, assessed up to 2 years

  • Quality of life

    From date of randomization until the follow-up ended, assessed up to 2 years

Procedure: VATS

Interventions

ESTDPROCEDURE

1. A 2-cm longitudinal mucosal incision was made, approximately 5cm proximal to the submucosal tumor (SMTs). 2. Submucosal dissection was done, creating a submucosal tunnel until the tumor was visible. 3. Dissection was done along the margin of the tumor. 4. After the tumor had been removed, the potential bleeding area in the tunnel was coagulated. 5. Endoclips were used to close the entry of the submucosal tunnel. (Gong W et al. ESTD for upper gastrointestinal submucosal tumors… Endoscopy 2012; 44: 231-235)

ESTD
VATSPROCEDURE

1. General anesthesia with double lumen intubation. 2. Three to four cameras or working ports are placed over the chest wall. 3. After the lesion is visualized by thoracoscopy, the mediastinal pleura over the tumor is incised longitudinally by an endoscopic hook electrocauterizer. 4. The mass is exposed after the overlying muscle is split longitudinally. 5. The retracting suture is placed over the mass and then meticulously dissect the plane between the mass and the submucosal layer. The integrity of the mucosa must be checked. 6. The muscle layer is re-approximated and a chest tube is place through one of the ports. (Luh et al. World Journal of Surgical Oncology 2012, 10:52)
