Can Minimally Invasive Esophagectomy Replace Open Esophagectomy for Esophageal Cancer? Latest Analysis of 24,233 Esophagectomies From the Japanese National Clinical Database
We aimed to elucidate whether minimally invasive esophagectomy () can be safely performed by reviewing the Japanese National Clinical Database.
Summary of Background Data:
MIE is being increasingly adopted, even for advanced esophageal cancer that requires various preoperative treatments. However, the superiority of MIE's short-term outcomes compared with those of open esophagectomy (OE) has not been definitively established in general clinical practice.
This study included 24,233 esophagectomies for esophageal cancer conducted between 2012 and 2016. Esophagectomy for clinical T4 and M1 stages, urgent esophagectomy, 2-stage esophagectomy, and R2 resection were excluded. The effects of preoperative treatment and surgery on short-term outcomes were analyzed using generalized estimating equations logistic regression analysis.
MIE was superior or equivalent to OE in terms of the incidence of most postoperative morbidities and surgery-related mortality, regardless of the type of preoperative treatment. Notably, MIE performed with no preoperative treatment was associated with significantly less incidence of any pulmonary morbidities, prolonged ventilation ≥48 hours, unplanned intubation, surgical site infection, and sepsis. However, reoperation within 30 days in patients with no preoperative treatment was frequently observed after MIE. The total surgery-related mortality rates of MIE and OE were 1.7% and 2.4%, respectively (P < 0.001). Increasing age, low preoperative activities of daily living, American Society of Anesthesiologists physical status ≥3, diabetes mellitus requiring insulin use, chronic obstructive pulmonary disease, congestive heart failure, creatinine ≥1.2 mg/dL, and lower hospital case volume were identified as independent risk factors for surgery-related mortality.
The results suggest that MIE can replace OE in various situations from the perspective of short-term outcome. 从短期结果看，MIE可以在任何情况下取代开放手术。
