Abstract Aim The aim of this study was to gain insight in the techniques and outcomes of RAMIE worldwide. Background & Methods Although robot-assisted minimally invasive esophagectomy (RAMIE) is increasingly adopted. The current literature on RAMIE mainly consists of single-center case series with considerable variation in reported techniques and outcomes. To gain an overview of the worldwide practice in RAMIE, an online registry was established by the Upper GI International Robotic Association (UGIRA). The collected data involve patient- and treatment characteristics, as well as postoperative outcomes that include complications as defined by the Esophageal Complications Consensus Group, length of stay, re-admissions (i.e. <30 days after discharge), mortality (i.e. in-hospital or <30 days after surgery), and pathological results. The outcomes were descriptively analyzed for this interim report. Results A total of 434 patients who underwent RAMIE for esophageal cancer between 2016-2019 were included in this interim analysis. The mean age was 63 years (SD ±9.7), the majority was male (n=359, 83%), and nearly all patients had an ASA score ≥2 (n=398, 92%). Adenocarcinoma (n=253, 58%) and squamous cell carcinoma (n=162, 37%) were most prevalent. The usual surgical approach was transthoracic (n=428, 99%) with the patient in semiprone position (n=393, 91%). Gastric conduit reconstruction was performed in all except one patient, who received a colonic interposition. The anastomosis was created by hand-sewing (n=207, 48%), circular stapling (n=142, 32%), or linear stapling (n=85, 20%). The median intraoperative blood loss was 120 milliliters (IQR 70-280) and the median operating time was 392 minutes (IQR 353-455). Postoperative complications occurred in 251 patients (59%) and mainly involved pulmonary complications (n=138, 32%), anastomotic leakage (n=80, 18%), and cardiac complications (n=55, 13%). Mortality occurred in 9 patients (2%) and re-admission because of complications was required in 57 patients (14%). A median of 28 lymph nodes (IQR 21-35) were removed and a radical resection was achieved in 400 patients (92%). Conclusion The presented results are the first to provide an overview of the techniques that are commonly used in RAMIE. By demonstrating results that are in line with recent benchmarking literature, this study demonstrates the safety and feasibility of RAMIE.

Abstract Aim To report the prospective experience in Hybrid Laparoscopic Robot-assisted Minimally-invasive Esophagectomy (HLRAMIE) in a referral Center. Background & Methods The minimally-invasive esophagectomy (MIE) is an attractive and established technique to improve the reduction of post-operative morbility with sound oncological results. The hybrid combination of laparoscopy and full robotic thoracic phase (HLRAMIE) is an approach aimed to be as effective as MIE to treat esophageal neoplasms. Inclusion criteria: patients undergone to multimodal medical advice panel, affected from non-cT4, from mid thoracic to cardia, esophageal neoplasms, with and without neoadjuvant treatment, fit for minimally-invasive surgery. HLRAMIE: laparoscopic stage plus full robotic thoracic stage by Da Vinci Xi® (Intuitive Surgical, US), with gastric-pull first-choice conduit. Prospective, dedicated database. Results From October 2015 to April 2019, 33 patients underwent to HLRAMIE (site of neoplasm: 1 mid thoracic; 9 inferior; 23 cardia). 5 out 33 were converted to open. 27/28 underwent to a Ivor Lewis esophagectomy, 1/28 to McKeown procedure. The mean total surgical time was 517 minutes, mean robotic docking time 12 min with mean thoracic time 269 min (positive trend). Gastric pull-up was performed in 28/28. In 23/28 patients the esophago-gastric anastomosis was performed full robotic after the fashion of hand, in 5/28 was performed by circular stapler. The mean extubation time was 12 hours. The mean number of lymph node removed was: overall fields 32.4 (range 15-58), thorax 9.8 (3-27). The mean number of metastatic lymph node was 3.8 (0-18). 100% were R0 resections. The mean hospital-stay was 15 days. The perioperative mortality and 30-day mortality were both 0%. The overall post-operative morbility was 32.1%. 4/28 (14.2%) patients developed an anastomotic leakage, 75% were managed by endoscopy. 11/28 (39.2%) patients developed a late anastomotic stenosis (all in the hand made group). Conclusion In our experience, HLRAMIE is surgically reproducible with the principle of learning curve; oncologically adequate in relation to radical dissection; safe and effective in relation to post-operative early morbility and mortality. Long-term follow up and more powerful, randomized series are needed to establish the definitive clinical and oncological results of HLRAMIE.

Abstract Background Surgical resection with radical lymphadenectomy is a pivotal component in the multidisciplinary therapy of esophageal cancer. Minimally invasive esophagectomy was shown to be effective in reducing the morbidity and was adopted increasingly. As a novel minimally invasive technique, robot-assisted esophagectomy remains in the initial stage ofapplication. This study describes the single-institution experience of robotic esophagectomy. Methods Between March 2016 and October 2017, 20 consecutive patients underwent robot assisted esophagectomy at our institute. The thoracic and abdominal mobilization were all performed with the assistance of the robot. We retrospectively collected the operative data and postoperative outcomes. Results The majority of patients were male (80%), and the median age was 62 years. The average operative time was 342 minutes (range 280–440). The average blood loss was 112 ml (range 50–400). No patient experienced conversion to a thoracotomy or laparotomy. R0 resection was achieved in all patients, the mean number of dissected lymph nodes was 19 (range 8–32). No 90-day operative mortality was observed, and postoperative complications were present in 8 of 20 patients (40.0%). Pulmonary complications were the most common event and were observed in 3 patients. Two patients experienced an anastomotic leak. Conclusion Our study demonstrated that robot-assisted esophagectomy is a safe and technically feasible alternative to conventional thoraco-laparoscopic esophagectomy.

Abstract   Single-incision thoracoscopic and laparoscopic procedures has have been applied in treating various diseases. However, it is limited in literature for such procedures used in treating esophageal cancer. Methods Minimally invasive esophagectomy (MIE) with a single-incision approach in the thoracoscopic and laparoscopic procedures was attempted in 144 patients with esophageal cancer. Results There was 96 patients underwent a McKeown procedure and 48 an Ivor Lewis procedure repectively. The mean ventilator usage of the patients after surgery was 0.3 ± 0.6 days, the mean ICU stay was 7.42 ± 17.15 days, and the mean number of dissected lymph nodes was 43.5 ± 21.8. There 11 patients suffered from postoperative complications, including 3 pulmonary complications, 4 anastomotic leakage and 4 vocal cord palsy. There are no 30-day mortality, however, there were one patient died from ARDS 40 days after surgery. Conclusion Single-port MIE seems to be a feasible option for treating patients with esophageal cancer, which offers an acceptable perioperative surgical outcome. However, the long-term survival results of the patients requires to be follow-up in the future.

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 Background Patients  with esophageal cancer  that invades adjacent structures (cT4b) are precluded from surgery and usually treated with definitive chemoradiotherapy (dCRT). dCRT might result in sufficient downstaging to enable a radical resection, possibly improving survival. This study aimed to assess the perioperative and oncologic outcomes of a salvage robot-assisted minimally invasive esophagectomy (RAMIE) in patients with cT4b esophageal cancer after dCRT. Methods Between June 2012 and November 2019, patients who underwent a RAMIE with a gastric conduit reconstruction after completion of dCRT for cT4b esophageal carcinoma were identified from a prospectively maintained surgical database at the University Medical Center Utrecht. Results In total, 24 patients with a histopathologically confirmed T4b adenocarcinoma or squamous cell carcinoma of the esophagus were included. The adjacent organs involved were the tracheobronchial tree (67%), aorta (21%) or both (13%). No conversions or major intraoperative complications were observed. A radical resection was achieved in 22 patients (92%), and a pathologic complete response was observed in 13 (54%) patients. Postoperative grade 2 or higher complications occurred in 20 patients (83%). The disease-free survival at 24 months was 68% for the patients in whom a radical resection was achieved. Conclusion In patients with cT4b esophageal cancer treated with dCRT followed by a salvage RAMIE, a radical resection rate of 92% was achieved, with acceptable complications and promising survival rates. These results demonstrate the feasibility of a curative surgical treatment for patients with initially irresectable esophageal cancer but underscore the importance of a proper preoperative patient selection.

Abstract Aim The aim of this study was to describe the results of a structured training pathway that was developed to implement robot-assisted minimally invasive esophagectomy (RAMIE) in new centers. Background & Methods To safely and effectively implement RAMIE in new centers, the learning process needs to be optimized. In this context, a structured training pathway was created (Table 1). The results of this training pathway were investigated by evaluating consecutive patients who underwent RAMIE by a single surgeon who followed the structured training pathway. These patients were included from the trainee center’s prospective database. Cumulative sum (CUSUM) learning curves were plotted for thoracic operating time and intraoperative blood loss. Perioperative outcomes were compared between patients who underwent surgery before and after a learning curve plateau occurred. Results Between 2017-2018, the trainee team adhered to the structured training pathway and a total of 70 patients were included. The learning curves showed plateaus after 22 cases. In cases 23-70, the operating time was shorter for both the thoracic phase (median 215 vs. 249 minutes, P=0.001) and overall procedure (median 394 vs. 440 minutes, P=0.005), intraoperative blood loss was less (median 210 vs. 400 milliliters, P=0.029), and lymph node yield was higher (median 32 vs. 23 nodes, P=0.001) when compared to the first 22 cases. No significant differences were found for conversion rates, postoperative complications, length of hospital stay, radicality, or mortality. Conclusions The structured RAMIE training pathway results in a short learning curve and is an effective way to introduce RAMIE without compromising the oncological outcomes and complication rates. The pathway is therefore advised to surgeons who are willing to adopt this technique.
