SUMMARY The circular mechanical and hand-sewn intrathoracic anastomosis are most often used in robot-assisted minimally invasive esophagectomy (RAMIE). The aim of this study was to describe the technical details of both techniques that were pioneered in two high volume centers for RAMIE. A prospectively maintained database was used to identify patients with esophageal cancer who underwent RAMIE with intrathoracic anastomosis. The primary outcome was anastomotic leakage, which was analyzed using a moving average curve. For the hand-sewn anastomosis, video recordings were reviewed to evaluate number of sutures and distances between the anastomosis and the longitudinal staple line or gastric conduit tip. Between 2016 and 2019, a total of 68 patients with a hand-sewn anastomosis and 60 patients with a circular-stapled anastomosis were included in the study. For the hand-sewn anastomosis, the moving average curve for anastomotic leakage (including grade 1–3) started at a rate of 40% (cases 1–10) and ended at 10% (cases 59–68). For the circular-stapled anastomosis, the moving average started at 10% (cases 1–10) and ended at 20% (cases 51–60). This study showed the technical details and refinements that were applied in developing two different anastomotic techniques for RAMIE. Results markedly improved during the period of development with specific changes in technique for the hand-sewn anastomosis. The circular-stapled anastomosis showed a more stable rate of performance.

Abstract Aim The aim of this study was to describe a technique that was developed and refined to construct a hand-sewn intrathoracic anastomosis during robot-assisted minimally invasive esophagectomy (RAMIE). Background & Methods Whilst some case series have reported promising results of a hand-sewn intrathoracic anastomosis during RAMIE, the exact techniques were often not described in detail. Therefore, the current single-center retrospective study was designed to provide a detailed and reproducible technical description of a hand-sewn, intrathoracic anastomosis that was developed and refined for patients who underwent RAMIE in a high volume center for esophageal cancer surgery (2016-2018). Video recordings were reviewed to evaluate technical details regarding the anastomosis, including number of sutures and distances between the anastomosis and the longitudinal staple line or gastric conduit tip. Technical details and distances were extracted and measured by using video analysis software. Moving average analyses were performed to evaluate whether the anastomotic leakage rate changed over the consecutive cases. Results A total of 68 patients were included in the study. For creation of the anastomosis, the gastric conduit was opened on a median distance of 19 millimeters (range 0-66) from the gastric conduit tip. After initially performing end-to-end anastomoses, a switch was made to an end-to-side anastomosis for the majority of 55 patients (81%). A median total of 27 sews (range 20-38) were required to close the anastomosis. In the last 22 patients of the cohort (32%), 4 tension release stitches were placed after circular suturing of the anastomosis. A re-inforcing omental wrap was positioned around the anastomosis in 64 patients (94%). The moving average curve for anastomotic leakage started at a rate of 40% (cases 1-10) and ended at 10% (cases 59-68). Conclusion This is the first study to report technical features and outcomes of a hand-sewn intrathoracic anastomosis during RAMIE in detail. Although an acceptable anastomotic leakage rate was observed in the final inclusion phase, a hand-sewn intrathoracic anastomosis during RAMIE may carry a substantial learning curve.

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 Robot-assisted minimally invasive esophagectomy (RAMIE) is increasingly being adopted as the preferred surgical treatment for esophageal cancer, as it is superior to open esophagectomy and a good alternative to conventional minimally invasive esophagectomy. This paper addresses the technical details of the thoracoscopic phase of RAMIE, including the operating room set-up, patient positioning, port placement, and surgical steps.
