RESUMO
INTRODUCTION: In minimally invasive esophagectomy, a circular stapled anastomosis is common, but no evidence exists investigating the role of the specific localization of the anastomosis. The aim of this study is to evaluate the impact of an esophagogastrostomy on the anterior or posterior wall of the gastric conduit on the postoperative outcomes. MATERIAL AND METHODS: All oncologic minimally invasive Ivor Lewis procedures, performed between 2017 and 2022, were included in this study. The cohort was divided in two groups: a) intrathoracic esophagogastrostomy on the anterior gastric wall of the conduit (ANT, n = 285, 65%) and b) on the posterior gastric wall (POST, n = 154, 35%). Clinicopathological parameters and short-term outcomes were compared between both groups by retrieving data from the prospective database. RESULTS: Overall, 439 patients were included, baseline characteristics were similar in both groups, there was a higher proportion of squamous cell carcinoma in ANT (22.8% vs. 16.2%, P = 0.043). A higher rate of robotic-assisted procedures was observed in ANT (71.2% vs. 49.4%). Anastomotic leakage rate was similar in both groups (ANT 10.4% vs. POST 9.8%, P = 0.851). Overall complication rate and Clavien-Dindo > 3 complication rates were higher in POST compared to ANT: 53.2% vs. 40% (P = 0.008) and 36.9% vs. 25.7% (P = 0.014), respectively. The rate of delayed gastric emptying (20.1% vs. 7.4%, P < 0.001) and nosocomial pneumonia (22.1% vs. 14.8%, P = 0.05) was significantly higher in POST. CONCLUSION: Patients undergoing minimally invasive Ivor Lewis esophagectomy with an intrathoracic circular stapled anastomosis may benefit from esophagogastrostomy on the anterior wall of the gastric conduit, in terms of lower rate of delayed gastric emptying.

Minimally invasive esophagectomies, including robot-assisted procedures, have demonstrated superiority over traditional open surgery. Despite the prevalence of transhiatal and transthoracic approaches, cervical access is less common in minimally invasive esophageal surgery. Advancements in robotic systems, such as the daVinci Single-Port (SP), now enable controlled transcervical extrapleural mediastinoscopic access, potentially reducing pulmonary complications and extending surgical options to patients with comorbidities. The daVinci SP Robot-Assisted Cervical Esophagectomy (SP-RACE) employs a single port and laparoscopic approach, demonstrating feasibility with comparable lymphadenectomy and recurrent nerve palsy rates to transthoracic methods. This technique, performed for the first time in Europe at the University Hospital Mainz, involves a transcervical SP-phase that allows for effective mediastinal dissection and esophageal mobilization. Despite technical challenges due to limited space, robotic systems enhance controlled access and eliminate arm collision. The daVinci SP platform's advantages include improved triangulation, fewer interferences, and better control of instruments in confined spaces. This novel approach shows promise for patients with high esophageal tumors and those unsuitable for transthoracic surgery, warranting further investigation into its clinical utility and reproducibility.
RESUMO
Minimally invasive Ivor-Lewis Esophagectomy (MIE) is widely accepted as a surgical treatment of resectable esophageal cancer. Aim of this paper is to describe the surgical details of our standardized MIE technique and its safety. We also evaluate the esophageal mobilization in semiprone compared to the left lateral position. A retrospective analysis of 141 consecutive patients who underwent Ivor-Lewis esophagectomy for cancer, from February 2016 to September 2021, was conducted. All the procedures were performed by totally thoraco-laparoscopic with an intrathoracic end-to-side circular stapled anastomosis. Thoracic phase was performed in left lateral position (LLP-group, n=47) followed by a semiprone position (SP-group, n=94). The intraoperative and postoperative outcomes were prospectively collected and analyzed. The procedure was completed without intraoperative complication in 94.68% of cases in SP-group and in 93.62% of cases in LLP-group (P=0.99). The total operative time and thoracic operative time were significantly shorter in SP-group (P=0.0096; P=0.009). No statistically significant differences were detected in postoperative outcomes between the groups, except for anastomotic strictures (higher in LLP-group, P=0.02) and intensive care unit stay (longer in LLP-group, P=00.1). No reoperation was needed in any cases. Surgical radicality was comparable; the median of harvested lymph nodes was significantly higher in SP-group (P<0.0001). The present semiprone technique of thoraco-laparoscopic Ivor-Lewis esophagectomy is safe and feasible but may also provide some advantages in terms of lymph nodes harvested and total operation time.

Robotic-assisted minimally invasive esophagectomy (RAMIE) represents an established approach for the treatment of esophageal cancer. Aim of this study is to evaluate the feasibility and safety of our technique for performing the intrathoracic anastomosis during RAMIE.All the procedures were performed by the same surgeon using the same technique for performing the intrathoracic anastomosis. Intraoperative and postoperative outcomes were recorded. Postoperative complications were classified according to the Esophagectomy Complications Consensus Group (ECCG); the primary outcome was the evaluation of the feasibility and safety of our technique. From 2016 to 2021, 204 patients underwent Ivor Lewis RAMIE at our Center. Two patients (0.9%) were converted during the thoracic phase. The anastomosis was completed in all the other patients forming complete anastomotic rings. The median duration for the robotic-assisted thoracoscopic phase was 224 minutes. Twenty-two of the RAMIE-Ivor Lewis patients had an anastomotic leakage (10.3%). The overall 90-day postoperative mortality was 1.9%. The procedure resulted to be feasible and safe in our cohort of patients.

Minimally Invasive Esophagectomy for Esophageal Cancer Abstract. Oncological esophagectomy with gastric pull up and intrathoracic represents the standard surgical procedure in the curative treatment of malignant tumors of the esophagus and the esophagogastric junction. The procedure, as two or three body cavities are accessed, has a natural level of invasiveness, which suggests lowering the surgical trauma using minimally invasive surgery (MIS). Because of the complexity of the surgical procedure, minimally invasive esophagectomy is an operation with relevant surgical learning curve. As of now, two principally different minimally invasive techniques for esophageal resection are established in clinical routine in specialized centers, the conventional laparoscopy/thoracoscopy based method and the robotic approach. Benefits of minimally invasive esophagectomy are reduced pulmonary complications and reduced postoperative pain. The surgical radicality of both minimally invasive techniques is at least comparable to the open approach and combined MIS/open approach, long-term survival outcomes from randomized controlled trials are pending. The robotic surgical technology has evolved dramatically over the last decade and oncological esophagectomy offers meaningful opportunity for application. Due to further technological progress, robotic surgery is expected to play an even more important role in the future. Focusing on the direct comparison of conventional minimally invasive esophagectomy and robotic-assisted esophagectomy, the randomized ROBOT-2 trial will reveal important evidence.

GERD and Barett: Natural Course of One Disease - Update Diagnostics and Therapy Abstract. The gastroesophageal reflux disease (GERD) represents a relatively frequent condition, which clinically includes orocervical, thoracic and abdominal complaints. GERD is defined as pathological gastroesophageal acidic reflux, which consecutively leads to mucosal damage of the esophagus such as reflux esophagitis. The most common symptom of GERD is heartburn but GERD symptoms include various complaints, which need to be considered in diagnosis and therapy. Besides endoscopy, barium swallow, pH metry and manometry are counted among the routine diagnostics for GERD patients. For therapy, dietary and lifestyle measures come along with medication such as proton pump inhibitors (PPI) as daily medication and antacids on demand. It has been demonstrated that anti-reflux surgery, minimally invasive fundoplication or magnet augmentation of the lower esophageal sphincter, produces an equal and lasting effect on GERD compared to PPI. Surgery is preferred in case of large hiatal hernia of voluminous reflux. Success of therapy is given if esophageal exposure to acid is reduced, which shows in remission of esophagitis or which can be demonstrated through pH-metry control. Additionally, improvement of quality of life stands in the focus of GERD treatment, which is to be considered for every therapeutic step. Barrett esophagus represents a subtype of GERD with rising incidence in Western countries. As potential precancerous lesion, the Barrett's esophagus is to be diagnosed early and needs to undergo a risk stratified surveillance in order to prevent dysplasia or carcinoma. Patients with low grade dysplasia, high grade dysplasia or early Barrett's carcinoma should be treated endoscopically. Soon artificial intelligence might contribute to improvement of Barrett's esophagus surveillance and treatment.

To ensure safe implementation of robot-assisted minimally invasive esophagectomy (RAMIE), the learning process should be optimized. This study aimed to report the results of a surgeon who implemented RAMIE in a German high-volume center by following a tailored and structured training pathway that involved proctoring. Consecutive patients who underwent RAMIE during the course of the program were included from a prospective database. A single surgeon, who had prior experience in conventional MIE, performed all RAMIE procedures. Cumulative sum (CUSUM) learning curves were plotted for the thoracic operating time and intraoperative blood loss. Perioperative outcomes were compared between patients who underwent surgery before and after a learning curve plateau occurred. Between 2017 and 2018, the adopting center adhered to the structured training pathway, and a total of 70 patients were included in the analysis. The CUSUM learning curves showed plateaus after 22 cases. In consecutive cases 23 to 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 cases 1 to 22. No significant differences were found in terms of conversion rates, postoperative complications, length of stay, completeness of resection, or mortality. In conclusion, the structured training pathway resulted in a short and safe learning curve for RAMIE in this single center's experience. As the pathway seems effective in implementing RAMIE without compromising the early oncological outcomes and complication rates, it is advised for surgeons who are wanting to adopt this technique.

The full robotic-assisted minimally invasive esophagectomy (RAMIE) is an upcoming approach in the treatment of esophageal and junctional cancer. Potential benefits are seen in angulated precise maneuvers in the abdominal part as well as in the thoracic part, but due to the novelty of this approach the optimal setting of the trocars, the instruments and the operating setting is still under debate. Hereafter, we present a technical description of the 'Mainz technique' of the abdominal part of RAMIE carried out as Ivor Lewis procedure. Postoperative complication rate and duration of the abdominal part of 100 consecutive patients from University Medical Center in Mainz are illustrated. In addition, the abdominal phase of the full RAMIE is discussed in general.

INTRODUCTION: Head-mounted mixed-reality technologies may enable advanced intraoperative visualization during visceral surgery. In this technical note, we describe an innovative use of real-time mixed reality during robotic-assisted transanal total mesorectal excision. TECHNIQUE: Video signals from the robotic console and video endoscopic transanal approach were displayed on a virtual monitor using a head-up display. The surgeon, assistant, and a surgical trainee used this technique during abdominal and transanal robotic-assisted total mesorectal excision. We evaluated the feasibility and usability of this approach with the use of validated scales. RESULTS: The technical feasibility of the real-time visualization provided by the current setup was demonstrated for both the robotic and transanal parts of the surgery. The surgeon, assistant, and trainee each used the mixed-reality device for 15, 55, and 35 minutes. All participants handled the device intuitively and reported a high level of comfort during the surgery. The task load was easily manageable (task load index: <4/21), although the surgeon and assistant both noted a short delay in the real-time video. CONCLUSION: The implementation of head-mounted mixed-reality technology during robotic-assisted transanal total mesorectal excision can benefit the operating surgeon, assistant, and surgical trainee. Further improvements in display quality, connectivity, and systems integration are necessary.

Robotic-assisted surgery is rapidly increasing, especially in general surgery. It has been shown for years that the minimal invasive esophagectomy (MIE) is possible using a robotic system, for example, da Vinci Xi, Intuitive Surgical. In the past, most robotic esophageal resections have been performed thoracoscopically, and the anastomosis was mostly sutured at the neck. Due to the increase of usable instruments and technical progress, it is possible to perform the total abdominothoracic esophagectomy with an intrathoracic sutured anastomosis robotically. In this article, we would like to present the standardized operation technique and tricks for the robotic-assisted (da Vinci Xi) Ivor Lewis MIE (RAMIE), especially the robotic technique in combination with a standardized intrathoracic circular end-to-side stapled esophagogastric anastomosis.

Robotic surgery is gaining importance in complex thoracoscopic surgery, such as robotic-assisted minimally invasive esophagectomy (RAMIE). The RAMIE procedure was designed using the first generation of the robotic system. The latest da Vinci Xi system has substantially increased the dexterity, especially designed for multiquadrant surgery. The original three-arm RAMIE approach was modified including the robotic four-arm use for the thoracoscopic and laparoscopic part of the operation. This extended approach (four-arm RAMIE approach) provides more flexibility and raises the independence of the surgeon.

BACKGROUND: Pelvic intraoperative neuromonitoring during nerve-sparing robot-assisted total mesorectal excision (RTME) is feasible. However, visual separation of the neuromonitoring process from the surgeon console interrupts the workflow and limits the usefulness of available information as the procedure progresses. Since the robotic surgical system provides multi-image views in the surgeon console, the aim of this study was to integrate cystomanometry and internal anal sphincter electromyography signals to aid the robotic surgeon in his/her nerve-sparing technique. METHODS: We prospectively investigated 5 consecutive patients (1 male, 4 females) who underwent RTME for rectal cancer at our institution in 2017. The robotic surgery was performed using the da Vinci Xi combined with pelvic intraoperative neuromapping with real-time electromyography and cystomanometry signal transmission by multi-image view during RTME. RESULTS: The adapted two-dimensional pelvic intraoperative neuromonitoring imaging successfully simulcasted to the surgeon console view in all 5 cases. The technical note is complemented by an intraoperative video. CONCLUSIONS: This report demonstrates the technical feasibility of an improved neuromonitoring process during nerve-sparing RTME. Robotic neuromapping can be fully visualized from the surgeon console.

Introduction: Several studies reported the advantages of minimally invasive esophagectomy over the conventional open approach, particularly in terms of postoperative morbidity and mortality. The literature regarding the elderly population is however scarce and it is still not clear whether elderly patients may benefit from a minimally invasive approach as the general population. We sought to evaluate whether thoracoscopic/ laparoscopic (MIE) or fully robotic (RAMIE) Ivor-Lewis esophagectomy significantly reduces postoperative morbidity in the elderly population. Methods: We analyzed data of patients who underwent open esophagectomy or MIE/RAMIE at Mainz University Hospital and at Padova University Hospital between 2016 and 2021. Elderly patients were defined as those ≥ 75 years old. Clinical characteristics and the postoperative outcomes were compared between elderly patients who underwent open esophagectomy or MIE/RAMIE. A 1-to-1 matched comparison was also performed. Patients < 75 years old were evaluated as a control group. Results: Among elderly patients MIE/RAMIE were associated with a lower overall morbidity (39.7% vs. 62.7%, p=0.005), less pulmonary complications (32.8 vs. 56.9%, p=0.003) and a shorter hospital stay (13 vs. 18 days, p=0.03). Comparable findings were obtained after matching. Similarly, among < 75 years-old patients, a reduced morbidity (31.2% vs. 43.5%, p=0.01) and less pulmonary complications (22% vs. 36%, p=0.001) were detected in the minimally invasive group. Discussion: Minimally invasive esophagectomy improves the postoperative course of elderly patients reducing the overall incidence of postoperative complications, particularly of pulmonary complications.
RESUMO
Esophageal submucosal tumors (SMTs) are rare heterogenous clinical entities. The surgical resection can be performed in different surgical approaches. However, the robotic surgical strategy is poorly documented in the treatment of SMTs. We present our series of operated esophageal SMTs approached via robotic-assisted surgery. Six patients with symptomatic esophageal submucosal tumors underwent robotic surgery within a 3-year period. The performed procedures were robotic-assisted enucleation, robotic esophagectomy (RAMIE) and reverse hybrid robotic esophagectomy. Patients' clinical data, intra/postoperative outcomes, and histopathological features were retrieved from the institution's prospective database. Five of six patients were scheduled for upfront surgery: four underwent robotic enucleation (three leiomyoma and one suspected GIST) and one underwent reverse hybrid robotic esophagectomy (suspected GIST). One patient, diagnosed with GIST, was treated with neoadjuvant Imatinib therapy, before undergoing a RAMIE. No major intra-operative complications were recorded. Median length of stay was 7 days (6-50), with a longer post-operative course in patients who underwent esophagectomy. Clavien-Dindo > 3a complications occurred in two patients, aspiration pneumonia and delayed gastric emptying. The final histopathological and immuno-histochemical diagnosis were leiomyoma, well-differentiated GIST, low-grade fibromyxoid sarcoma and Schwannoma. Robotic-assisted surgery seems to be a promising option for surgical treatment strategies of benign or borderline esophageal submucosal tumors.

BACKGROUND: Currently 4 surgical techniques are performed for transthoracic esophagectomy (open esophagectomy (OE), hybrid esophagectomy (HE), conventional minimally invasive esophagectomy (MIE) and robot assisted minimally invasive esophagectomy (RAMIE). Aim of this study was to compare these 4 different esophagectomy approaches regarding postoperative complications and short term oncologic outcomes. METHODS: Between 2008 and 2019, consecutive patients who underwent esophagectomy with gastric conduit reconstruction were included in this single center study. The primary outcome of this study was the incidence of postoperative complications. RESULTS: Overall 422 patients (OE (n = 107), HE (n = 101), MIE (n = 91) and RAMIE (n = 123)) were evaluated. Uncomplicated postoperative course was observed in 27% (OE), 34% (HE), 53% (MIE), and 63% (RAMIE) of patients (p < 0.001). Pulmonary complications were observed in 57% (OE), 44% (HE), 28% (MIE), and 21% (RAMIE) of patients (p < 0.001). Cardiac complications were present in 25% (OE), 23% (HE), 9% (MIE), and 11% (RAMIE) of patients (p < 0.001). MIE and RAMIE were associated with fewer wound infections (p < 0.001). Median hospital stay after MIE (13 days) and RAMIE (12 days) was shorter compared to OE (20 days) and HE (17 days) (p < 0.001). A median number of 21 (OE), 23 (HE), 23 (MIE), and 31 (RAMIE) lymph nodes was harvested (p < 0.001). CONCLUSION: Total minimally invasive esophagectomy (MIE, RAMIE) was associated with a lower overall, pulmonary, cardiac and wound complication rate as well as a shorter hospital stay compared to open or hybrid approach (OE, HE). RAMIE resulted in higher lymph node harvest than MIE.

PURPOSE: Radiation-induced esophageal cancer (RIEC) is a rare but severe late consequence of radiotherapy. The literature regarding this topic is predominately limited in describing the risk of this disease. Tumor behavior, treatment strategies, and prognosis of this cancer remain poorly defined. PATIENTS AND METHODS: We collected data of patients who were referred to our unit between 2000 and 2020 for RIEC. After tumor board discussion, upfront surgery or neoadjuvant therapy and surgery were indicated as the main treatment. Preoperative characteristics, long-term and short-term postoperative outcomes of RIEC patients were compared with a 1:1 clustering-matched cohort of patients affected by primary esophageal cancer (PEC). RESULTS: At pre-matching, 54 RIEC and 936 PEC patients were enrolled. The median time between primary irradiation and diagnosis of RIEC was 13.5 years, and the median primary radiation dose was 60 Gy. Compared to the unmatched cohort of PECs, RIEC patients were more frequently female (p = 0.0007), had earlier detection of disease (p = 0.03) and presented more frequently with upper esophageal cancers (p < 0.0001). Neoadjuvant treatment was used less frequently in RIEC patients (p < 0.0001). After matching, the 51 RIEC and 50 PEC patients showed comparable results in terms of exposure to neoadjuvant treatment, surgical radicality and survival outcomes. RIEC patients had more severe postoperative complications (p = 0.04) and a higher proportion of pulmonary complications (p = 0.04). CONCLUSIONS: Curative treatments are feasible for RIEC. Neoadjuvant chemotherapy or chemoradiation can be used in this subgroup, treatment response and long-term outcomes are comparable to those of PEC. The risk of postoperative complications is probably related to the detrimental effect of primary irradiation on lung function.

BACKGROUND: Robot-assisted minimally invasive esophagectomy (RAMIE) with intrathoracic anastomosis is gaining popularity as a treatment for esophageal cancer. The aim of this study was to describe postoperative complications and short-term oncologic outcomes for RAMIE procedures using the da Vinci Xi robotic system 4-arm technique. METHODS: Data of 100 consecutive patients with esophageal or gastro-esophageal junction 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. Intraoperative and postoperative complications were graded according to Esophagectomy Complications Consensus Group (ECCG) definitions. RESULTS: Mean duration was 416 min (±80); 70% of patients had an uncomplicated postoperative recovery. Pulmonary complications were observed in 17% of patients. Anastomotic leakage was observed in 8% of patients. Median ICU stay was 1 day and median overall postoperative hospital stay was 11 days. The 30-day mortality was 1%; 90-day mortality was 3%. A R0 resection was reached in 92% of patients with a median number of 29 dissected lymph nodes. All patients had at least 7 months of follow-up with a median follow-up of 17 months. Median overall survival was not reached yet. CONCLUSION: RAMIE with intrathoracic anastomosis (Ivor Lewis) for esophageal or gastro-esophageal junction cancer was technically feasible and safe. Postoperative complications and short-term oncologic results were comparable to the highest international standards nowadays.

The surgical treatment of gastric cancer has arrived at a turning point towards the routine application of minimally invasive techniques. After the first results of prospective randomized trials from Asia confirmed the surgical and oncological safety, the latest results of international trials provided evidence for minimally invasive gastrectomy of advanced gastric cancer in a multimodal setting. A new addition in the field of minimally invasive procedures is robotic-assisted surgical techniques, which have already been implemented for these indications in many centers in Germany. The technical advantages that are applicable in the robotics setting in comparison to laparoscopy lead to a rapid dissemination of the procedure but still need to be evaluated in controlled trials. Further developments for the surgical treatment of gastric cancer are found in the field of intraoperative imaging procedures. In this field various technologies are available, such as fluorescence imaging using a near-infrared camera, which requires the use of a fluorescent agent or the hyperspectral camera system, which does not require the application of a fluorophore and merges pictures from visible and non-visible wavelengths to a functional image. It is to be expected that in the future various technological advancements can make a valuable contribution to the surgical treatment of gastric cancer in the clinical routine, especially if they support and facilitate the use of minimally invasive surgical techniques.

BACKGROUND: With the introduction of minimally invasive esophagectomy, postoperative complications rates have decreased. Daily laboratory tests are used to screen patients for postoperative complications. The course of inflammatory indicators after esophagectomy after different surgical approaches has not been described yet. The aim of the study was to describe the postoperative C-reactive protein (CRP) and leukocyte levels after different surgical approaches for esophagectomy and relate it to postoperative complications. METHODS: Between 2010 and 2018, 217 consecutive patients underwent thoracoabdominal esophagectomy with gastric conduit reconstruction. Blood tests to assess CRP and leukocytes were performed daily in all patients. Differences between treatment groups were analyzed with a linear mixed model. All postoperative complications were recorded in a prospective database. Prognostic factors were analyzed using multivariate logistic regression modeling. RESULTS: The study evaluated 4 different esophagectomy techniques: open (n = 57), hybrid (n = 53), totally minimally invasive (n = 52), and robot-assisted minimally invasive (n = 55). The increase of inflammatory indicators was significantly higher after open esophagectomy on the first 2 postoperative days compared with the 3 minimally invasive procedures (P < .001). Postoperative CRP values exceeding 200 mg/L on the second postoperative day and open esophagectomy were independently associated with postoperative complications. CONCLUSIONS: Open esophagectomy results in significantly higher CRP and leukocyte values compared with hybrid, minimally invasive, and robot-assisted minimally invasive esophagectomy. Open esophagectomy and a CRP increase on the second postoperative day above 200 mg/L are independent positive predictors for postoperative complications in multivariate analysis.

We report a case of a 69-year-old patient with esophageal cancer and severe upper gastrointestinal bleeding during neoadjuvant radiochemotherapy who required mass transfusion followed by complex emergency procedures. Despite endoscopic stenting, the bleeding recurred, and thus emergency open surgery was required. Gastric wedge resection of the minor curvature necessitated by perforation caused by the endoscopic stent maneuver and duodenotomy with ligation of the gastroduodenal artery, as the cause of persistent intraluminal bleeding, were performed. The already prepared gastric conduit during the emergency operation did not become ischemic, even though the gastroduodenal artery, left gastric artery, and short gastric arteries were ligated during emergency surgery. After 2 months of recovery, a computed tomographic scan showed collateral perfusion of the conduit via the superior mesenteric artery. Therefore, a fully robotic (abdominal and thoracic) esophagectomy with pull-up of the gastric conduit was performed, with no post-surgical complications. The patient was discharged 10 days after the robotic esophagectomy. Six months after esophagectomy, the patient is in a good condition.
