Mesoesophageal dissection

OBJECTIVE: Total mesoesophageal excision (TME) is a promising procedure. Prone position thoracoscopic-assisted TME might be a good choice, even without robust evidence yet. Therefore, it is necessary to explore the safety and efficacy of this procedure. METHODS: We retrospectively analyzed the short-term outcomes regarding intraoperative unplanned events, postoperative complications, and lymphadenectomy in 61 patients who underwent prone position thoracoscopic-assisted TME from June, 2020 to August, 2021...

Based in the anatomical concept of the mesoesophagus, that at subcarinal level all the vessels come through a by-layer connective tissue plane from the aorta to the esophagus whereas supracarinally these structures will come from both sides, with vagal and recurrent laryngeal nerves, a minimally invasive mesoesophageal (MIME) resection model may be described. Based on this surgical plane concept, dissection of esophagus and mediastinal lymphadenectomy can be performed along these structures establishing clear anatomical modules for an adequate oncological resection...

BACKGROUND: This study evaluates the feasibility and strategy of left tracheobronchial lymph node (LN) dissection in the surgical treatment of esophageal cancer, and its impact on surgical outcomes following thoracoscopic esophagectomy. METHODS: Data of 265 patients with thoracic esophageal cancer who underwent thoracoscopic and laparoscopic esophagectomy was retrospectively reviewed. In 80 cases, thoracoscopic esophagectomy was performed without left tracheobronchial LN dissection (group non-4L), while 185 cases underwent thoracoscopic esophageal mobilization with routine left tracheobronchial node dissection (group 4L)...

BACKGROUND: Most surgeons consider esophageal carcinoma with lymph node involvement a systemic disease. However, it is possible that the disease may be localized in the earlier phases of lymphatic metastasis. The distribution of involved lesions in the initial phase of lymph node metastasis has not been thoroughly investigated yet. METHODS: Among 329 patients that underwent curative (R0 International Union Against Cancer [UICC]) esophagectomy with systematic mesoesophageal dissection, 51 cases of patients with only 1 involved lymph node (solitary involvement) were retrospectively investigated and compared with patients with multiple involved lymph nodes...

BACKGROUND: The clinical significance of lymph node involvement along the recurrent laryngeal nerves in cancer of the thoracic esophagus is still controversial. Although these lymph nodes are anatomically located in a well-defined compartment (proximal mesoesophagus), appropriate procedures for dissecting them are not well established. STUDY DESIGN: We retrospectively investigated clinical results over the past 10 years in 276 patients who underwent systematic dissection of cervical, mediastinal, and upper abdominal lymph nodes...
