Abstract Aim The aim of this study was to describe postoperative complications and short-term oncologic outcomes for RAMIE4 with intrathoracic anastomosis for esophageal cancer within our case series of 100 consecutive patients. Background & Methods Robot assisted minimally-invasive esophagectomy (RAMIE) with intrathoracic anastomosis is gaining popularity as a treatment for esophageal cancer. In this study, we present the results of 100 RAMIE procedures using the da Vinci Xi robotic system (RAMIE4). The aim of this study was to describe postoperative complications and short-term oncologic outcomes for RAMIE4 within our case series of 100 consecutive patients. Between January 2017 and February 2019, data of 100 consecutive patients with esophageal carcinoma undergoing modified Ivor-Lewis esophagectomy were prospectively collected. All operations were performed by the same surgeon using an identical intrathoracic anastomotic reconstruction technique with the same perioperative management and pain control regimen. Intra-operatively and post operatively complications were graded according to definitions stated by the Esophagectomy Complications Consensus Group (ECCG). Results Mean duration of the surgical procedure was 416 min (± 80). In total, 70 patients (70%) had an uncomplicated operative procedure and postoperative recovery. Pulmonary complications were most common and were observed in 17 patients (17 %). Anastomotic leakage was observed in 8 patients (8%). Median ICU stay was 1 day and median overall postoperative hospital stay was 11 days. 30 day mortality was 1%. A R0 resection was reached in 92% of patients with a median number of 29 dissected lymph nodes. Conclusion RAMIE4 with intrathoracic anastomosis for esophageal cancer or cancer located in the esophagus was technically feasible and safe. Postoperative complications and short term oncologic results were comparable to the highest international standards nowadays. These results could only be obtained due to a structured RAMIE training pathway. The superiority of RAMIE compared to conventional minimally invasive esophagus is currently investigated in multiple randomized controlled trials. Results of these trials will define the role for RAMIE for patients with esophageal cancer in the future.

Abstract   Da Vinci Surgical System Xi was introduced in our institution in 2017. Since then we started robot-assisted minimally invasive esophagectomy (RAMIE) as private practice. Japanese national insurance system started to reimburse RAMIE in 2018. Since then, the number of RAMIE is explosively increasing. Currently the indication of RAMIE in our institution purely depends on machine availability. However, the real clinical benefit of RAMIE over conventional minimally invasive esophagectomy (MIE) remains unknown. Methods Between January 2015 and January 2020, data of 156 consecutive patients with esophageal carcinoma undergoing esophagectomy was retrospectively reviewed. After exclusion of 12 salvage esophagectomy for patients after definitive chemoradiotherapy (>50Gy), 10 mediastinoscopic esophagectomy, 5 esophagectomy without upper mediastinal dissection, 2 two-stage esophagectomy and 1 total pharyngo-laryngo-esophagectomy, 126 patients (46 RAMIE and 80 MIE) were included in the analysis. The 1:1 propensity score match analysis was performed to compare the short-term outcomes between RAMIE and MIE. Results After matching, 45 RAMIE and 45 MIE were analyzed. RAMIE took significantly longer thoracic operation time (370 min vs. 288 min; P < 0.0001). Intraoperative blood loss (80 g vs. 50 g; P = 0.0759), harvested thoracic nodes (22 vs 25; P = 0.1188), harvested upper mediastinal nodes (12 vs 12; P = 0.4233) were similar. RAMIE showed less severe postoperative morbidity (Clavien-Dindo Grade III or higher) (9% vs. 22%; P = 0.0810) and lower incidence of recurrent laryngeal nerve palsy (Clavien-Dindo Grade II or higher) (7% vs. 18%; P = 0.1076). There was no postoperative death in both groups. Conclusion Although this result contains our early learning curve period of RAMIE, short term outcome of RAMIE is acceptable from a safety point of view.

Abstract   Although minimally invasive esophagectomy (MIE) has been performed for esophageal cancer worldwide, intra-thoracic anastomosis under prone positions is still challenging. In this retrospective study, we reviewed our short-term results of this anastomotic technique in our institution. Methods From November 2016 to December 2019, we performed 319 esophagectomies. Of these patients, 28 patients (9%) underwent intra-thoracic esophago-gastric anastomosis under MIE. Procedures The left side of an esophageal stump which had been closed using a linear stapler was opened for anastomosis. Then, the anterior wall of a gastric conduit, around 5 cm below the tip, was opened for anastomosis. Linear staplers were inserted in both esophageal stump and gastric conduit and side-to-side anastomosis was performed. The opening for insertion was closed using a hand-sewn anastomosis in 2 layers. Results Five patients (18%) suffered anastomotic leakage with Clavien-Dindo 2 and 3a, and all of them recovered by conservative treatments. Two patients (2/19, 11%) showed anastomotic stricture which improved by several endoscopic dilatations. Six patients (6/19, 32%) showed the reflux esophagitis of Grade C. Conclusion Although we have not experienced severe or critical post-operative complications, the short-term results of intra-thoracic anastomosis under MIE were not sufficient. Additional progresses in techniques are required.
