Aim: Esophagectomy is associated with several post-operative complications (50%-70%) due to surgical trauma. Minimally invasive techniques have therefore been applied to decrease mortality and morbidity. Robotassisted minimally-invasive esophagectomy (RAMIE) was developed to overcome the drawbacks of the thoracolaparoscopic approach. The objective of this systematic review is to report some recent experiences and to compare RAMIE with other approaches to esophagectomy, focusing on technical and oncological aspects. Methods: Pubmed, Embase and Scopus databases were searched for "robot-assisted esophagectomy", "minimally invasive esophagectomy" and "robotic esophagectomy" in January 2020. The study was focused on original papers on totally endoscopic RAMIE in the English language. No statistical procedures (meta-analysis) were performed. Results: Three hundred and twenty studies were identified across the database and after screening and reviewing, 14 were included for final analysis. The overall 90-day post-operative mortality after trans-thoracic esophagectomy ranged from 0% to 9% and did not differ between approaches. Post-operative complications ranged between 24% and 60.9%: respiratory (6.25% to 65%), cardiac (0.8% to 32%), anastomotic leak (3.1% and 37.5%) and vocal cord palsy (9.1%-35%) were the most frequent. The evidence for long-term outcomes is weak, with no significant differences in overall survival, disease-free survival and recurrence identified in comparison with other approaches. The selected papers showed that RAMIE had comparable outcomes between the open and thoraco-laparoscopic approaches within a multimodal treatment pathway. Conclusion: RAMIE also seems to be associated with better lymph node dissection, nerve sparing and quality of life, but larger studies are needed to obtain more evidence.

Background Currently, little is known regarding the optimal technique for the abdominal phase of RAMIE. The aim of this study was to investigate the outcome of robot-assisted minimally invasive esophagectomy (RAMIE) in both the abdominal and thoracic phase (full RAMIE) compared to laparoscopy during the abdominal phase (hybrid laparoscopic RAMIE). Methods This retrospective propensity-score matched analysis of the International Upper Gastrointestinal International Robotic Association (UGIRA) database included 807 RAMIE procedures with intrathoracic anastomosis between 2017 and 2021 from 23 centers. Results After propensity-score matching, 296 hybrid laparoscopic RAMIE patients were compared to 296 full RAMIE patients. Both groups were equal regarding intraoperative blood loss (median 200 ml versus 197 ml, p = 0.6967), operational time (mean 430.3 min versus 417.7 min, p = 0.1032), conversion rate during abdominal phase (2.4% versus 1.7%, p = 0.560), radical resection (R0) rate (95.6% versus 96.3%, p = 0.8526) and total lymph node yield (mean 30.4 versus 29.5, p = 0.3834). The hybrid laparoscopic RAMIE group showed higher rates of anastomotic leakage (28.0% versus 16.6%, p = 0.001) and Clavien Dindo grade 3a or higher (45.3% versus 26.0%, p < 0.001). The length of stay on intensive care unit (median 3 days versus 2 days, p = 0.0005) and in-hospital (median 15 days versus 12 days, p < 0.0001) were longer for the hybrid laparoscopic RAMIE group. Conclusions Hybrid laparoscopic RAMIE and full RAMIE were oncologically equivalent with a potential decrease of postoperative complications and shorter (intensive care) stay after full RAMIE.

Trends in the evolution to robot-assisted minimally invasive thoracoscopic esophagectomy
Mini-invasive Surgery , 2020
Much effort has been made to improve outcomes and/or minimize the invasiveness of esophagectomy for thoracic esophageal cancer. This has led to the evolution from open esophagectomy to thoracoscopic minimally invasive esophagectomy (MIE), and from MIE to robot-assisted minimally invasive esophagectomy (RAMIE). RAMIE is being applied clinically to overcome the limitations of MIE. In this article, we review the trends in the evolution from thoracoscopic MIE to RAMIE. It has now been demonstrated that RAMIE is both safe and feasible, and may decrease morbidity and mortality rates associated with esophagectomy and improve oncological outcomes. On the other hand, there are still many problems that need to be solved.

The use of the surgical robot has been increasing in thoracic surgery. Its three-dimensional view and instruments with surgical wrists may provide advantages over traditional thoracoscopic techniques. Our initial experience with thoracoscopic robot-assisted minimally invasive esophagectomy (RAMIE) for esophageal cancer was compared with our traditional thoracoscopic minimally invasive esophagectomy (MIE) approach for esophageal cancer. A retrospective review of a prospective database was performed. From July 2008 to October 2009, 43 patients underwent MIE resection. Patients who had benign disease and intrathoracic anastomosis were excluded. Results are presented as mean Ϯ SD. Significance was set as P < 0.05. Eleven patients who underwent RAMIE and 26 who underwent MIE were included in the cohort. No differences in age, sex, race, body mass index, or preoperative radiotherapy or chemotherapy between the groups were observed. No significant differences in operative time, blood loss, number of resected lymph nodes, postoperative complications, days of mechanical ventilation, length of intensive care unit stay, or length of hospital stay were also observed. In this short-term study, RAMIE was found to be equivalent to thoracoscopic MIE and did not offer clear advantages.
Robotic-assisted minimally invasive esophagectomy
Annals of Esophagus
Open transthoracic esophagectomy (OE), video-assisted minimally invasive esophagectomy (MIE) and roboticassisted minimally invasive esophagectomy (RAMIE) are commonly accepted approaches to esophageal resection for advanced benign and malignant disease (3-5). The OE approach has been associated with higher perioperative morbidity in comparison to the MIE and RAMIE approaches (6). Reduced surgical trauma (blood loss, surgical site and pulmonary infections), hospital duration, and overall morbidity, are documented as advantageous benefits of the MIE approach in comparison to the OE

Background: Robot-assisted surgery may have a role in improving oncological outcomes in esophagectomy. Especially in the anatomical areas in the chest that are more difficult to reach in open surgery (including the superior mediastinum). The dexterity of the robotic instruments aid in performing a more extensive nodal dissection and the precision and detailed vision of the robotic system potentially improves staging, oncological outcomes and reduces complications (i.e., recurrent nerve palsy). In this article, we describe our experience and clinical outcomes in patients treated by robot assisted minimal invasive esophagectomy (RAMIE) in cN+ esophageal cancer patients with positive nodes localized in the superior mediastinum. Methods: From May 2007-2018, all patients who had involved nodes by either fluor-18-deoxyglucose positron-emission-tomography-computed tomography (FDG-PET-CT) or endoscopic ultrasound (EUS) + fine needle aspiration (FNA) localized in the superior mediastinum (above level Th4/sternal angle) were identified. Patient characteristics, perioperative data, postoperative clinical outcomes/complications and overall survival were prospectively recorded and retrospectively evaluated. Results: Forty patients (48% adenocarcinoma) met our inclusion criteria. All patients underwent a three-stage procedure with cervical anastomosis and 90% of the patients underwent neoadjuvant chemoradiotherapy. Mortality occurred in three patients (7.5%), of which two were caused by severe acute respiratory distress syndrome (ARDS). The most frequent complications were pneumonia (25%), chylothorax (20%), anastomotic leakage (17.5%) and vocal cord paralysis (17.5%) which was grade 1 in 72% of the patients. Radicality rate (R0 resection) was 98% and the average lymph node yield was 24 (range, 9-57). Median overall and disease-free survival was 26 and 17 months, respectively. Conclusions: RAMIE for esophageal cancer patients with node positive disease in the superior mediastinum is associated with increased mortality/morbidity. Oncological outcome showed excellent lymph node yield, R0 rate and survival was equal compared to patients with lower mediastinal node positive disease.
Robotic-assisted minimally invasive esophagectomy: past, present and future
Journal of Thoracic Disease
Esophagectomy for cancer of the esophagus is increasingly performed using minimally invasive techniques. After the introduction of minimally invasive esophagectomy (MIE) in the early 1990's, roboticassisted techniques followed after the turn of the millennium. The advent of robotic platforms has allowed the development of robotic-assisted minimally invasive esophagectomy (RAMIE) over the past 15 years. Although recent trials have shown superior peri-operative morbidity and quality of life compared to open esophagectomy, no randomized trials have compared RAMIE to conventional MIE. This paper summarizes the current literature on RAMIE and provides an overview of expected future developments in robotic surgery.
Robot-assisted transhiatal esophagectomy: a 3-year single-center experience
Diseases of the Esophagus, 2012
Minimally invasive esophagectomy has emerged as an important procedure for disease management in esophageal cancer (EC) with clear margin status, less morbidity, and shorter hospital stays compared with open procedures. The experience with transhiatal approach robotic esophagectomy (RE) for dissection of thoracic esophagus and associated morbidity is described here. Between March 2007 and November 2010, 40 patients with resectable esophageal indications underwent transhiatal RE at the institute. Clinical data for all patients were collected prospectively. Of 40 patients undergoing RE, one patient had an extensive benign stricture, one had high-grade dysplasia, and 38 had EC. Five patients were converted from robotic to open. Median operative time and estimated blood loss were 311 minutes and 97.2 mL, respectively. Median intensive care unit stay was 1 day (range, 0-16), and median length of hospital stay was 9 days (range, 6-36). Postoperative complications frequently observed were anastomotic stricture (n = 27), recurrent laryngeal nerve paresis (n = 14), anastomotic leak (n = 10), pneumonia (n = 8), and pleural effusion (n = 18). Incidence rates of laryngeal nerve paresis (35%) and leak rate (25%) were somewhat higher in comparison with that reported in literature. However, all vocal cord injuries were temporary, and all leaks healed following opening of the cervical incision and drainage. None of the patients died in the hospital, and 30-day mortality was 2.5% (1/40). Median number of lymph nodes removed was 20 (range, 3-38). In 33 patients with known lymph node locations, median of four (range, 0-12) nodes was obtained from the mediastinum, and median of 15 (range, 1-26) was obtained from the abdomen. R0 resection was achieved in 94.7% of patients. At the end of the follow-up period, 25 patients were alive, 13 were deceased, and 2 patients were lost to follow-up. For patients with EC, median disease-free survival was 20 months (range, 3-45). Transhiatal RE, by experience, is a feasible albeit evolving oncologic operation with low hospital mortality. The benefits include minimally invasive mediastinal dissection without thoracotomy or thoracoscopy. A reasonable operative time with minimal blood loss and postoperative morbidity can be achieved, in spite of the technically demanding nature of the procedure. Broader use of this technology in a setting of high-volume comprehensive surgical programs will almost certainly reduce the complication rates. Robotic tanshiatal esophagectomy with the elimination of a thoracic approach should be considered an option for the appropriate patient population in a comprehensive esophageal program.
