As a result, specific terms are often used out of their intended context. To simplify the nomenclature, two points regarding procedures for surgical resection of the esophagus are critical: the extent of resection (radical vs standard) and the operative approach (choice of incisions). It is important to understand that the radicality of the resection may have little to do with the operative approach, with the exception of esophagectomy without thoracotomy (transhiatal esophagectomy), which mandates the performance of a standard or non-radical resection. Esophagectomy has emerged as the standard curative treatment option for patients with esophageal carcinoma; however, unlike the surgical resection of other types of solid tumors, many different surgical options and/or approaches exist for these patients. This heterogeneity of care may result from the fact that the esophagus is accessible through more than one body cavity (left hemithorax, right hemithorax, abdomen).In addition, and partially as a result of its accessibility,different types of surgical specialists harbor this operation in their armamentarium, including general surgeons,thoracic surgeons, and surgical oncologists. Despite this enthusiasm amongst surgeons, little consensus exists as to which option is most oncologically sound. Further, the details of the various surgical approaches and procedures for resection of the esophagus are often difficult to comprehend, even for specialists in gastrointestinal disease, with much of the relevant terminology used out of its intended context. To facilitate the understanding of the surgical options for esophageal carcinoma, it is useful to view the operation from two angles: the extent of resection (Aradical@ vs Astandard@) and the operative approach (choice of incisions).展开更多

The modem universities are the formal social organizations, and that the universities implement the bureaucratic administration has its own rationality which is not negligible. However, the universities are the academic organizations, and their intrinsic attributes, that is, the ambiguity of their goals, the diversified values, and the uncertainty of the processes of their activities and the effects, result in the inevitable limitations in the bureaucratic administration of the universities. Therefore, the improvement of the university bureaucratic administration systems should be implemented based on the inherent logic of the universities.展开更多
