RESUMEN
A method of acquiring radial pulse information from the grid-net area on every pulse image frame is proposed based on the principle of lens imaging and the characteristics of image data. The radial pulse image data are collected by the pulse image sensor. Multi-points out-of-plane displacements of the pulse are acquired by the method. And the membrane surfaces are reconstructed, then the 3D information of the pulse can be observable.

Lymphangioma of the esophagus is an extremely rare submucosal benign tumor. Most esophageal lymphangiomas reported in the literature are smaller than 2 cm in diameter and can be removed using endoscopy. We report a case of lymphangioma of the esophagus with 2 huge lesions (10×2.5×1 cm and 6×5×4 cm) that were completely resected by open thoracotomy and enucleation. The patient recovered without any complications.

OBJECTIVE: To evaluate the efficacy and safety of video-assisted thoracoscopic (VATS) esophagectomy in the treatment of esophageal cancer. METHODS: From June 2004 to October 2007, video-assisted thoracoscopic esophagectomy was performed in 36 patients, including 29 men and 7 women with median age of 58.9 years old. The cancer located at upper segment in 5 cases, middle 25 cases and lower 6 cases. VATS approach was used to mobilize the intrathoracic esophagus and stomach was mobilized by open approach. Esophagogastric anastomosis was performed in the left neck. RESULTS: The mean operative time was 250 minutes (190-330 min) and average time of VATS was 70 minutes. The mean hospital stay was 8.7 days. Mean lymph node harvest was 14.3 nodes. Post-operative complications occurred in 11 patients(30.6%), but no perioperative death occurred. CONCLUSION: Video-assisted thoracoscopic esophagectomy is technically feasible and safe with lower morbidity and shorter hospital stay as compared to open procedure, and may replace the open esophagectomy in selected patients.
