Minimally invasive esophagectomy/ gastroesophagectomy for cancer - Long term results from a single institution
Keywords:Esophageal cancer, Minimal invasive esophagectomy, Esophagectomy, NACT
Background: Esophagectomy is a complex operation. Minimally invasive esophagectomy (MIE) may decrease the morbidity and mortality of resection. The aim of this study was to produce long term outcome of MIE from a single center in Nepal.
Methods: Patients with squamous cell carcinoma and adenocarcinoma of esophagus/ gastroesophageal junction who underwent MIE between 2001-2018 were analyzed.
Results: 215 patients were taken for MIE during 2001-2018. There was 11.2% conversion rate. Totally MIE approach was performed in 43% cases and hybrid MIE in 57% cases. Mean operative time, intra operative blood loss, anastomotic leak, pulmonary infection, recurrent laryngeal nerve injury and in-hospital mortality were 246 min, 286 ml, 13.1%, 9%, 6.8% and 3%, respectively. Final histopathology revealed most common Stages III and IV in 51.2% and 36.1%, respectively. The median survival was 34 months and 5-OS was 27%. 5-OS was 27% and o% for R0 and R+ resection (p<.001). Median survival after radical and non-radical lymphadenectomy was 36 months and 25 months (p=.003), respectively. Responders to neoadjuvant treatment had the best survival.
Conclusion: MIE has got acceptable post operative morbidities. R0 resection, early stage of disease, radical lymphadenectomy and responders to neoadjuvant treatment had got the best survival results
