PS01.212: OUTCOMES OF HYBRID VERSUS FULLY MINIMALLY INVASIVE 2-STAGE ESOPHAGECTOMY FOR CANCER OF THE DISTAL ESOPHAGUS AND GASTRO-ESOPHAGEAL JUNCTION

Abstract

Abstract Background Esophagectomy is associated with high complication rate and mortality. Numerous approaches have been introduced over the last two decades, with the ambition of reducing rate of complications, morbidity and mortality. Two-stage minimally invasive esophagectomies include hybrid (laparoscopic/thoracotomic) and fully minimally invasive and have recently gained popularity in the treatment of distal esophageal and gastro-esophageal junction cancer. We aim to compare the short-term outcomes between 2-stage hybrid and fully minimally invasive esophagectomy with intrathoracic hand-sewn anastomosis. Methods A retrospective analysis of a 4-year period prospectively collected data of 100 consecutive 2-stage minimally invasive esophagectomies was conducted. All operations were performed in a UK tertiary centre by a single surgical team between 2014 and 2018. All 3-stage and open esophagectomies were excluded from the study. A comparison of anastomotic leak rate, ITU length of stay, hospital length of stay, pulmonary complications, cardiac complications and 30 and 90-day mortality rates was made. Statistical analysis was performed using Graph-Prism 7.04. Results Seventy patients underwent hybrid and 30 underwent fully minimally invasive esophagectomy with intra-thoracic manual anastomosis. Chest infection and anastomotic leak rate were higher in the hybrid group (21.4% vs 16.8% and 10% vs 3.3%); however, cardiac complications were two times more common in fully minimally invasive compared to hybrid esophagectomies (3.3% vs 1.4%). Fully minimally invasive esophagectomies were associated with a shorter ITU stay as well as hospital length of stay compared to hybrid esophagectomies (5.5 vs 6.2 days, P = 0.47 and 10.5 vs 15.6 days P = 0.0018). Complete tumour resection (R0) rate was slightly higher in hybrid compared to fully minimally invasive esophagectomies (70.8% vs 64.3%). Thirty and 90-day mortality rate was 6.67% (1 cardiac and 1 respiratory arrest) in fully minimally invasive and 1.43% in hybrid esophagectomies. None of the mortality cases were related to surgical complications like anastomotic leak or conduit necrosis. Conclusion In our study 2-stage fully minimally invasive esophagectomy is associated with reduced post-operative complication rates compared to 2-stage hybrid oesophagectomy. Further larger studies are needed to assess the 30- and 90-day mortality risk associated with both procedures. Disclosure All authors have declared no conflicts of interest.
