Abstract
BACKGROUND: Video-assisted minimally invasive esophagectomy (MIE) has been widely applied in clinical practice. However, the optimal port design for thoracoscopic esophagectomy and lymphadenectomy has not been well established. Here we introduced our novel ergonomic thoracic port design as well as our novel procedures of lymphadenectomy via tissue interactive retraction and compared its effects with that of conventional port design in this pilot study. METHODS: Patients undergoing McKeown MIE from January 2018 to December 2018 in one surgical team were randomly assigned into the ergonomic port design group and conventional port design group. Data of baseline characteristics, perioperative outcomes, and ergonomic assessment were collected and compared between the two groups. RESULTS: A total of 70 patients undergoing curative McKeown MIE were randomly assigned and there were 35 patients in each group. The baseline characteristics between the two groups were comparable and well-matched. Moreover, there was no significant difference of number of total dissected lymph nodes, positive lymph nodes and total dissected mediastinal lymph nodes between the two groups. As for perioperative outcomes, there was also no significant difference of in-operating time and blood loss in the thoracic part between the two groups. However, there were significantly less times of forced pause of the surgeon by fatigue during thoracic part in the ergonomic group compared to conventional group (mean time: 1.1 vs. 7.4, respectively; P<0.001) and the symptom score referable to the musculoskeletal system by the surgeon was significantly lower in the ergonomic group than in the conventional group (2.3 vs. 7.6; P<0.001). Postoperatively, there was no significant difference of hospital stay duration and rate of complication and 30-day mortality between the two groups. CONCLUSIONS: Our novel thoracoscopic port design and procedures of lymphadenectomy was proved to be feasible and ergonomic, which could be easily mastered by most of the thoracic surgeons. 2019 Annals of Translational Medicine.
