For purposes of this survey, readers were asked to assume that they consulted on an otherwise healthy middle aged patient with a distal esophageal adenocarcinoma, T1bN0 by EUS. There were no contraindications to esophagectomy.
A relatively small number of respondents participated in this survey, which perhaps reflects the small amount of penetration of MIE in the thoracic surgery community and the small amount of interest in esophageal surgery among thoracic surgeons in some regions. Of those who did participate, 73% had some familiarity with MIE, whereas 26% did only open resections.
Of surgeons who currently perform MIE, 29% learned it during training and 59% learned it after completing their formal training. Twelve percent of respondents indicated that they were learning MIE techniques in other ways.
Among surgeons who perform MIE, 43% use a totally minimally invasive technique, whereas most of the rest used a hybrid technique, opening either the abdomen or the chest.
Over 50% of respondents indicated that their comfort level with MIE was either high or very high. Two-thirds of respondents indicated that they routinely caution patients about the possible need to convert to an open procedure.
A relatively high percentage of respondents (44%) indicated that they are currently teaching residents or fellows to perform MIE. The majority of respondents indicated that 25 MIEs were necessary for trainees to achieve adequate skill in performing this procedure. More than half of the respondents (61%) did not believe that a short course focused on MIE was sufficient to learn the procedure.
In contrast to prior surveys, the vast majority of respondents were from North America, which perhaps correlates with the lack of esophageal experience/training/expertise among thoracic surgeons on other continents.
