Anastomotic leak is the most dangerous complication occurring after esophagectomy and its relationship with inadequate visceral perfusion is widely recognized. Currently, the adequate perfusion of the gastric conduit is intraoperatively assessed by surgeons using subjective indicators (e.g., serosal color or pulsatile flow of vessels). During the last decades, several innovative optical techniques based on the interaction of light with tissue have been developed to monitor perfusion in esophagogastric surgery. However, these innovative approaches are characterized by a lack of video rate and reproducibility. They also provide operator-dependent results and lengthen the surgical workflow. Single Snapshot imaging of Optical Properties (SSOP) is an optical technique, which can overcome such limitations, providing quantitative information on the optical properties of biological tissues over a large field of view. It is the first study to demonstrate the accuracy of SSOP in the quantification of serosal StO2% in a porcine gastric conduit model.

Postoperative imaging plays a key role in the identification of complications after Ivor-Lewis esophagectomy (ILE). Careful analysis of imaging examinations can help identify the cause of the presenting symptoms and the mechanism of the complication. The complex surgical procedure used in ILE results in anatomical changes that make imaging interpretation challenging for many radiologists. The purpose of this review was to make radiologists more familiar with the imaging findings of normal anatomical changes and those of complications following ILE to enable accurate evaluation of patients with an altered postoperative course. Anastomotic leak, gastric conduit necrosis and pleuropulmonary complications are the most serious complications after ILE. Computed tomography used in conjunction with oral administration of contrast material is the preferred diagnostic tool, although it conveys limited sensitivity for the diagnosis of anastomotic fistula. In combination with early endoscopic assessment, it can also help early recognition of complications and appropriate therapeutic management.

To compare complications following totally minimally invasive (TMIE), laparoscopically assisted (hybrid) and open Ivor Lewis esophagectomy in patients with esophageal cancer. Three randomized trials have reported benefits for minimally invasive esophagectomy. Two studies compared TMIE versus open esophagectomy and another compared hybrid versus open Ivor Lewis esophagectomy. Only small retrospective studies compared TMIE with hybrid Ivor Lewis esophagectomy. Methods Data were used from the International Esodata Study Group assessing patients undergoing TMIE, hybrid or open Ivor Lewis esophagectomy. Primary outcome was pneumonia, secondary outcomes included incidence and severity of anastomotic leakage, (major) complications, length of stay, escalation of care and 90-day mortality. Data were analyzed using multivariate multilevel models. Results In total, 4733 patients were included in this study (TMIE:1472, hybrid:1364 and open:1897). Patients undergoing TMIE had lower incidence of pneumonia compared to hybrid (10.9% vs 16.3%, Odds Ratio (OR):0.56, 95%CI: 0.40–0.80) and open esophagectomy (10.9% vs 17.4%, OR:0.60, 95%CI: 0.42–0.84) and had shorter length of stay (median 10 days (IQR 8–16)) compared to hybrid (14 (11–19), p = 0.041) and open esophagectomy (11 (9–16), p = 0.027). Patients undergoing TMIE had higher rate of anastomotic leakage compared to hybrid (15.1% vs 10.7%, OR:1.47, 95%CI: 1.01–2.13) and open esophagectomy (7.3%, OR:1.73, 95%CI: 1.26–2.38). No differences were reported between hybrid and open esophagectomy. Conclusion Compared to hybrid and open Ivor Lewis esophagectomy, TMIE resulted in a lower pneumonia rate, a shorter hospital length of stay but a higher anastomotic leakage rate. The impact of these individual complications on survival and long-term quality of life should be further investigated.

Anastomotic leak following Ivor Lewis oesophago-gastrectomy is a major complication with high morbidity and mortality. We report our experience with three such cases where endoscopically deployed double pigtail stents (DPT) were used to help manage the leaks. Methods Three patients from October 1, 2019 to February 29, 2020 experienced leakage from the oesophago-gastric anastomosis following minimally invasive Ivor Lewis oesophago-gastrectomy. These occurred on post-operative day 9, day 29 and day 7 respectively. All cases were managed with endoscopic deployment of double pigtail stents along with other adjunctive measures. Results To date all patients remain alive, with sepsis under control. One of the patients had been able to have his double pigtail stent removed at six weeks and he has been able to commence adjuvant chemotherapy. Another patient had a follow-up contrast study one week after DPT insertion which showed no further contrast extravasation and was able to recommence oral intake. The third patient has a left empyema (managed conservatively with a combination of internal DPT and external pigtail drainage) which is gradually resolving. Conclusion Endoscopically deployed DPTs are a useful tool in the armamentarium for managing oesophago-gastric anastomotic leaks in selected patients following Ivor Lewis oesophago-gastrectomy. They are advantageous in that stent migration does not appear to be an issue, nor is there any problem with leakage around the stent. Patients are mostly able to restart oral intake soon after insertion of DPTs. This reduces the morbidity associated with these anastomotic leaks, and reduces the number of interventions needed.

In early 2000s, cervical anastomosis after esophagectomy was associated with a higher rate of recurrent nerve trauma than thoracic anastomosis. Recently, new technologies have been developed that reduce surgical complications. Mediastinoscopic esophagectomy is reportedly less invasive and allows faster recovery than thoracoscopic esophagectomy. Intraoperative nerve monitoring (IONM) prevents recurrent laryngeal nerve (RNL) palsy. We present the case of minimally invasive mediastinoscopic Ivor-Lewis Esophagectomy (MMIE) under IONM performed on an elderly esophagogastric junction (EGJ) adenocarcinoma patient. Methods An 84-year old man was consulted for adenocarcinoma of GEJ without lymphnode metastasis. Despite his advanced age, he had no comorbidities. We planned to perform MMIE under IONM. The procedure started with a patient lithotomy, and three trocars plus small incision were made in the upper abdomen. Celiac lymphadenectomy was performed. Subsequently, a 35 mm incision was made in the left side of the neck and a monitor was attached to left vagus nerve. Three trocars were placed with single incision surgical devices and pneumomediastinum was noticed. Mediastinoscopic esophagectomy was performed. Gastric tube reconstruction via mediastinum with cervical anastomosis was performed. Results The operation was successful. Total operation time was 393 minutes, with an estimated blood loss of 5 mL. There were no intraoperative and postoperative complications, and no RLN palsy occurred. Conclusion MMIE with cervical anastomosis under IONM is safe and less invasive especially for the respiratory system as a thoracotomy is unnecessary.

One of the most feared complications of the esophagectomy for esophageal cancer is anastomotic leakage (AL). Early diagnosis is vital for timely initiation of therapeutic interventions as well as prompting early feeding in the absence of AL. The aim of this study is to investigate the role of serum C-reactive protein (CRP) and drain amylase levels in the early detection of AL. Methods All 109 patients who underwent a minimally invasive Ivor-Lewis procedure in our hospital between January 2018 and October 2020 were retrospectively included in this study. Data on CRP and drain amylase levels were collected during the first 5 postoperative days (POD) and were available for analyses. Mean CRP and median drain amylase levels between patients with and without AL were compared and ROC curves on POD 3, 4 and 5 were plotted to calculate cut-off values for CRP. Results In 13 of 109 patients (12%) AL was diagnosed with a median time to diagnosis of 8 days. Mean CRP was significantly higher in patients with AL on POD 3, 4 and 5. Cut-off values of 48, 113 and 90 mg/L had a high sensitivity of 100%, 92% and 92% on POD 3, 4 and 5. No difference in median drain amylase levels was observed. Conclusion CRP levels with a cut-off point of 113 mg/L on POD 4 do not improve earlier detection of AL, but has a high sensitivity for excluding AL while the value of drain amylase in the first 5 days after surgery is limited.

Anastomotic leak (AL) and conduit necrosis (CN) are among the most serious surgical complications after esophageal resection. Endoscopic, radiological and surgical methods are used in their treatment. The aim of this paper is to evaluate the results of the treatment of acute anastomotic complications after Ivor-Lewis esophagectomy in a single high-volume center. Methods We performed a retrospective audit of a consecutive cohort of 815 patients undergoing transthoracic esophagectomy with intrathoracic esophago-gastric anastomosis from 2005 to 2019. AL was graded according to Esophagectomy Complications Consensus Group recommendation. Results There were 79 patients with AL and 6 patients with CN (10%). AL type I, II and III was diagnosed in 33 (39%), 25 (29%) and 27 (32%) patients, respectively. Esophageal stent was used in 40 patients. Primary surgical revision (with/without stent insertion) was performed in 14 patients. Reoperation was necessary overall in 25 patients (29%). Seventeen patients (20%) ended-up with esophageal diversion. Treatment with esophageal stent was successful in 28/40 patients (70%). Endoscopic vacuum-therapy was successfully used in three patients for peristent leak after stent extraction. Mortality of severe AL (type II and III) was 10/52 patients (19%). Conclusion Successful management of acute anastomotic complications requires early diagnosis and an individual treatment approach with the use of endoscopic, radiological and surgical methods. The primary attempt for anastomosis preservation using esophageal stent is desirable. Considering the clinical condition and CT finding, we recommend not to hesitate with surgical revision with debridement and drainage of pleural cavity and mediastinum. If primary therapy fails, life-saving procedure is the esophageal diversion.

Background Minimal invasive Ivor-Lewis esophagectomy (MIIVE) with intrathoracic esophago-gastric anastomosis (EGA) is still under exploration and the preferred technique for intrathoracic anastomosis has not been established. Methods We retrospectively reviewed 43 consecutive patients who underwent MIIVE using the series technique called pretreatment-assisted robot intrathoracic layered anastomosis (PRILA), performed by a single surgeon between September 2018 and December 2020. The operative outcomes were analyzed. Results The mean total operation time had been reduced from 446.38±54.775 minutes (range, 354-552) in the first year to 347.70±60.420 minutes (range, 249-450) later. There were no conversions to thoracotomy. All the patients achieved R0 resection. No patient suffered from anastomotic leakage. There was no 30-day mortality. The median length of postoperative stay was 10.0 days. Conclusions PRILA further visualizes and streamlines the process of minimal invasive intrathoracic EGA, thus ensuring the precise anastomosis. It could be considered as a feasible alternative for intrathoracic EGA in MIILE.

Background The side‐to‐side anastomosis was considered a promising approach to create an intrathoracic esophagogastrostomy in the minimally invasive esophagectomy, with advantages over the side‐to‐end anastomosis with aspects of no need for additional mini‐thoracotomy and lower occurrence of stenosis. The hand‐sewing anterior aspect of the anastomosis is technically challenging in the thoracoscopic Ivor Lewis esophagectomy. Here we introduced our initial experience to facilitate this approach by using the surgical robot and barbed suture. Methods A retrospective study of all patients underwent robot‐assisted Ivor Lewis esophagectomy with side‐to‐side esophagogastrostomy from February 2016 to September 2018 was performed. The technical details are described in this paper. Results A total of 37 patients (35 male and 2 female, median age of 62.7 years) were successfully treated with completely robot‐assisted Ivor Lewis esophagectomy. The median total surgical time was 340 minutes including 65 minutes to perform the anastomosis. Median estimated blood loss was 120 mL and the length of hospital stay was 10 days. There was no 90‐day mortality. Three patients suffered anastomotic leakage (8.1%,3/37), who were successfully treated without reoperation. Conclusion Our initial results imply that it is technically feasible to perform intrathoracic gastroesophageal anastomosis by taking advantage of a robotic system and knotless suturing.

Surgical approaches for treating esophageal carcinoma include the transhiatal esophagectomy (THE) and the transthoracic esophagectomy (TTE) with the anastomosis in the thorax or the neck. Compared with THE, TTE can resect more extensive intrathoracic esophageal tumors. Meanwhile, the range of the resected mediastinal lymph nodes with TTE is wider than THE. Performing an intrathoracic esophagogastric anastomosis using MIE techniques can be technically challenging and time-consuming (1,2). Combined laparoscopic with thoracoscopic Ivor-Lewis esophagectomy needs video-assisted mini-thoracotomy and the use of Endo-GIA stapler over and over. Due to the use of OrVil system, the operation of the intrathoracic esophagus anastomosis has become easy, and the operation time has reduced.

A considerable number of reports have been published on the feasibility, techniques, and early postoperative results of robotic-assisted oesophageal surgery. However, these are mostly smaller case series, suggesting that the robot-assisted Ivor Lewis procedure is still in the implementation phase and far from being standardised. Oesophageal surgeons from seven robotic university centres in Germany, experienced in both minimally invasive and robot-assisted minimally invasive surgery, took part in a workshop on robot-assisted surgery. An intensive exchange of opinions and experiences, followed by a step-by-step re-enactment of the operation in a cadaver lab, enabled us to develop a standardised robot-assisted Ivor Lewis surgical workflow, which is presented here. Systematic and objective comparison of experiences and results using a robot-assisted Ivor Lewis procedure has made it possible to develop a standardised surgical workflow that is now clinically applied in our centres. It is hoped that standardisation of this procedure will help to maintain patient safety, prevent medical errors, and facilitate the learning curve, while introducing robotic surgery into a centre.

BACKGROUND: Oesophagectomy is a major complex operation associated with significant morbidity and mortality. Epidural analgesia has long been the gold standard postoperative analgesia but is associated with side-effects like hypotension, epidural haematoma and infection. In an attempt to lower morbidity and enhance recovery postoperatively, we have adopted the use of paravertebral catheter analgesia (PVCA) for patients undergoing totally minimal invasive oesophagectomy (TMIO). METHODS: Our objective was to review the current literature about the use of both PVCA and epidural analgesia. In addition, we evaluated the effect of PVCA in a large group of patients undergoing TMIO for cancer. We reviewed the records of 100 consecutive patients who had a TMIO with PVCA, spinal morphine, and PCA. Prospective independent scoring of postoperative pain, length of stay, high-dependency unit (HDU) stay, PVCA failure, the use of patient-controlled analgesia (PCA), and the use of vasoconstrictor medication postoperatively was analysed. RESULTS: One hundred consecutive patients received PVCA with PCA after the TMIO. Catheter related failures occurred in 4 cases. The median pain score over each of the 5 days were 0. The average pain score was highest in the first 24 hours and decreased over the next 4 days postoperatively. The use of PCA was highest in the first 2 days and reduced daily over the subsequent 3 days. Seven patients required rescue analgesia in the form of intercostal nerve (ICN) block. Spinal morphine was successful in 94% of cases. Vasoconstrictors were required in 19% on day 1 and 3% on day 2, postoperatively. CONCLUSIONS: Intraoperative placement of PVCA results in good postoperative pain control after a TMIO. This technique is simple, safe, reproducible and with very low failure rates. Therefore, it should be used instead of epidural catheter analgesia.

In the face of an increasingly aged population, surgical management in the elderly will rise. This study assesses the short-term outcomes of esophagectomies in octogenarians.The National Surgical Quality Improvement Program database was queried for esophagectomy cases from 2005 to 2014. Patients aged80 and ≥80 y were compared in univariate and multivariate analysis, controlling for confounding variables.Among 9354 esophagectomies, 4.3% were performed in patients aged ≥80 y. Ivor Lewis was the most common approach, comprising 43% of cases. Octogenarians more frequently had dependent functional status (P 0.0001) and cardiovascular disease (P 0.0001), whereas younger patients were more likely obese (P 0.0001), smokers (P 0.0001), and have excess preoperative weight loss (P = 0.0043). Compared to younger patients, in multivariate analysis, elderly patients were noted to have increased risk of 30-d mortality (odds ratio [OR] 1.67; confidence interval [CI] 1.03-2.67), discharge to facility (OR 3.08; CI 2.36-4.02), myocardial infarction (OR 2.49; CI 1.29-4.82), and pneumonia (OR 1.47; CI 1.12-1.910). However, regardless of age, dependent functional status demonstrated the strongest association with mortality (OR 3.41; CI 2.14-6.61). Within the elderly, each additional year above 80 y old increased the risk of discharge to a facility by 17% (OR 1.17; CI 1.04-1.30). Cases requiring nongastric intestinal conduit were also more likely to suffer from early mortality (OR 2.87; CI 1.87-4.40).Age is independently associated with multiple adverse outcomes, including mortality, discharge to facility, and postoperative cardiopulmonary complications. Functional dependence is even more so associated with poor outcomes. Careful selection of very elderly patients is required to minimize additional risk.

BACKGROUND The main clinical treatment for esophageal cancer is surgery. Since traditional open esophageal cancer resection has the disadvantages of large trauma, long recovery period, and high postoperative complication rate, its clinical application is gradually reduced. The current report of minimally invasive Ivor-Lewis esophagectomy (MIILE) is increasing. However, researchers found that patients with MIILE had a higher incidence of early delayed gastric emptying (DGE). AIM To investigate the influencing factors of postoperative early DGE after MIILE. METHODS A total of 156 patients diagnosed with esophageal cancer at Deyang People's Hospital were enrolled. According to the criteria of DGE, patients were assigned to a DGE group (n = 49) and a control group (n = 107). The differences between the DGE group and the control group were compared. Multivariate logistic regression analysis was used to further determine the influencing factors of postoperative early DGE. The receiver operating characteristic (ROC) curve was used to assess potential factors in predicting postoperative early DGE. RESULTS Age, intraoperative blood loss, chest drainage time, portion of anxiety score ≥ 45 points, analgesia pump use, postoperative to enteral nutrition interval, and postoperative fluid volume in the DGE group were higher than those in the control group. Perioperative albumin level in the DGE group was lower than that in the control group (P < 0.05). Age, anxiety score, perioperative albumin level, and postoperative fluid volume were independent factors influencing postoperative early DGE, and the differences were statistically significant (P < 0.05). The ROC curve analysis revealed that the area under the curve (AUC) for anxiety score was 0.720. The optimum cut-off value was 39, and the sensitivity and specificity were 80.37% and 65.31%, respectively. The AUC for postoperative fluid volume were 0.774. The optimal cut-off value was 1191.86 mL, and the sensitivity and specificity were 65.3% and 77.6%, respectively. The AUC for perioperative albumin level was 0.758. The optimum cut-off value was 26.75 g/L, and the sensitivity and specificity were 97.2% and 46.9%, respectively. CONCLUSION Advanced age, postoperative anxiety, perioperative albumin level, and postoperative fluid volume can increase the incidence of postoperative early DGE.

Oesophageal resection is a challenging procedure, and it is more so in patients who have undergone bariatric procedures, especially after laparoscopic sleeve gastrectomy. We present the case of a patient with a history of an laparoscopic sleeve gastrectomy who underwent a hybrid Ivor-Lewis oesophagectomy in which the sleeve was successfully used to reconstruct the upper gastrointestinal tract.

Objectives: To analyze the impact of the reversal penetrating technique (RPT) for intrathoracic gastroesophageal mechanical anastomosis on the development of anastomotic complications in Ivor Lewis minimally invasive esophagectomy (ILMIE) and further identify the risk factors for the development of anastomotic leakage and stricture.Methods: A retrospective observational study was conducted using clinical data of 316 patients with esophageal carcinoma (EC) who underwent ILMIE from January 2012 to December 2019. The participants were divided into three groups of RPT, transoral Orvil technique (TOT), or purse-string technique (PST) according to the different stapler placenent methods for intrathoracic mechanistic circular stapling. Multivariable analysis was performed to investigate the association of risk factors with anastomotic leakage and stricture.Results: There were 154 patients with RPT, 78 with TOT and 84 with PST intrathoracic gastroesophageal circular stapling in ILMIE. There was no differences in intraoperative anastomosis related conditions inclouding conversion of open operations, ways of esophageal reconstruction, lymph nodes harvested between the three groups. Whereas, The mean total operative time, and gastroesophageal anastomosis time in the RPT group were significantly shorter than those in other groups (both p

Summary This study aimed to demonstrate the learning curve of robot-assisted minimally invasive esophagectomy (RAMIE). A retrospective analysis of the first 124 consecutive patients who underwent RAMIE with intrathoracic anastomosis (Ivor Lewis) by a single surgeon between May 2015 and August 2020 was performed. An risk-adjusted cumulative sum (RA-CUSUM) analysis was applied to generate a learning curve of RAMIE considering the major complication rate, which reflected the technical proficiency. The overall 30-day morbidity rate was 38.7%, while the major complication rate was 25.8%. The learning curve was divided into two phases based on the RA-CUSUM analysis: phase I, the initial learning phase (cases 1–51) and phase II, the proficiency phase (cases 52–124). As we compared the proficiency phase with the initial learning phase, significantly decreased trends were observed in relation to the major complication rate (37.3% vs. 18.7%, P = 0.017), total operation time (330.9 ± 55.6 vs. 267.3 ± 39.1 minutes, P

Objective We introduced robotic-assisted Ivor Lewis esophagectomies (rob-E) using the da Vinci Xi in Oct. 2015. Prior to that, esophagectomies were performed as open Ivor Lewis (open-E) procedures. Aim of this study is to evaluate the safety of rob-E in comparison to open-E procedures regarding perioperative outcomes. Methods Retrospective analysis of prospectively collected data between Feb. 1999 and Dec. 2020. A case-matched analysis, matching open-E to rob-E in a 1:1 manner, was conducted. Cases were matched regarding age, gender, American Society of Anesthesiologists (ASA) score, histological type of tumor, tumor location and stage. Results In the study period 321 patients underwent an esophagectomy. 76 received rob-E and 245 open-E. After matching the cases the comparison of preoperative patient and tumor characteristics revealed no differences between the rob-E and open-E group regarding age at time of operation with a median of 69.5 (35-83) respectively 70 (46-88) years (p = 0.900), gender with 84.2% male in both groups (p = 1.000), ASA score with 68.4% ASA 3 or 4 in both groups (p = 1.000), percentage of tumor stage III of 53.9% respectively 57.9% (p = 0.707), and rate of neoadjuvant treatment of 82.9% in rob-E and 81.6% in open-E (p = 1.000). Conversion from rob-E to open-E was never necessary. For rob-E versus open-E no difference was found regarding overall morbidity with 69.7% versus 60.5% (p = 0.307), major morbidity (Clavien-Dindo > = 3b) with 11.8% versus 14.5% (p = 0.811), incidence of anastomotic insufficiency with 7.9% versus 5.3% (p = 0.745), rate of surgical reintervention with 5.3% versus 7.9% (p = 0.745), and mortality with 2.6% versus 3.9% (p = 1.000). Postoperative details showed no difference including a similar duration of hospitalization with a median of 20 (13-62) respectively 18.5 (13-52) days (p = 0.368) and number of harvested lymph nodes with a median of 24.5 (7-59) in rob-E and 23 (2-64) in open-E (p = 0.203). Conclusion The introduction of rob-E in our institution was safe, as perioperative morbidity and mortality did not differ from the previously performed open-E. Overall, the incidence of major morbidity and anastomotic insufficiency in rob-E and open-E show a satisfactory rate compared to previous reports in literature. Further studies with a larger cohort of rob-E are planned in order to draw more decisive conclusions.

Objective We introduced robotic-assisted Ivor Lewis esophagectomies (rob-E) using the da Vinci Xi in Oct. 2015. Two anastomotic techniques have been performed – continuously sutured (COSU) and linear-stapled (LIST). Aim of this study is to evaluate the two anastomotic techniques regarding perioperative outcomes in our experience. Methods Retrospective analysis of prospectively collected data between Oct. 2015 and Dec. 2020 including 76 patients. 45 underwent COSU and 31 LIST. Techniques are demonstrated with video material. Minor (Clavien-Dindo = 3b) morbidity, rate of anastomotic insufficiency, mortality, and duration of hospitalization were compared. Results Patient characteristics were as follows: median age of 69 (35-83) years in COSU and 70 (36-83) years in LIST (p = 0.575), male gender in 84.4% of COSU and 83.9% of LIST (p = 1.000), and physical status with American Society of Anesthesiologists score 3 in 62.2% of COSU and 67.7% of LIST (p = 0.771). Concerning tumor characteristics there were 91.1% adenocarcinomas in COSU and 96.8% in LIST (p = 0.642), whereas the others were squamous cell carcinomas and one neuroendocrine tumor in COSU. The tumors were stage II in 22.2% respectively 32.3% and stage III in 57.8% respectively 48.4% of COSU and LIST (p = 0.555). Comparison of minor morbidity occurring in 60.0% of COSU and 54.8% of LIST (p = 0.813), major morbidity in 8.9% respectively 16.1% (p = 0.473), incidence of anastomotic insufficiency in 8.9% of COSU and 6.5% of LIST (p = 1.000), rate of surgical reintervention necessary in 2.2% respectively 9.7% (p = 0.298) as well as mortality of 2.2% in COSU and 3.2% in LIST (p = 1.000) showed no difference. Median duration of hospitalization of 20 (13-49) days in COSU and 20 (14-62) in LIST (p = 0.423) did not differ. Conclusion In rob-E COSU and LIST show comparable results and a preferable technique cannot be determined yet. Our results do not support the results of previous reports (Cerfolio et al.) that demonstrated a superiority of LIST. While stapling the backside of the anastomosis in LIST impresses as an elegant way to overcome the surgical demanding part of the anastomosis, other disadvantages such as compromising perfusion of the gastric conduit may prevail and limit the benefits. Further studies with a larger cohort are planned in order to draw more decisive conclusions.

Purpose Symptom recurrence after initial surgical management of esophageal achalasia occurs in 10–25% of patients. The aim of this study was to analyze safety and efficacy of revisional therapy after failed Heller myotomy (HM). Methods A retrospective review of a prospective database was performed searching for patients with recurrent symptoms after primary surgical therapy for achalasia. Patients with previously failed HM were considered for the final analysis. The Foregut questionnaire, and the Atkinson and Eckardt scales were used to assess severity of symptoms. Objective investigations routinely included upper gastrointestinal endoscopy and barium swallow study. Redo treatments consisted of endoscopic pneumatic dilation (PD), laparoscopic HM, hybrid Ivor Lewis esophagectomy, or stapled cardioplasty. A yearly clinical and endoscopic follow-up was scheduled in all patients. Results Over a 20-year period, 26 patients with a median age of 66 years (IQR 19.5) underwent revisional therapy after failed HM for achalasia at a tertiary-care university hospital. The median time after index procedure was 10 years (IQR 21). Revisional therapy consisted of endoscopic pneumatic dilation (n=13), laparoscopic HM and fundoplication (n=10), esophagectomy (n=2), and stapled cardioplasty and fundoplication (n=1). Nine (34.6%) of these patients required further endoscopic or surgical treatments. There was no mortality, and the overall complication rate was 7.7%. At a median follow-up of 42 months (range 10–149), a significant decrease of dysphagia, regurgitation, chest pain, respiratory symptoms, and median Eckardt score (p Conclusion In specialized and multidisciplinary centers, revisional therapy for achalasia is feasible, safe, and effective.

Esophagectomy remains an operation with potential high morbidity and mortality. Minimally invasive esophagectomy (MIE) has gained popularity over the last two decades as an oncologically equivalent alternative to open esophagectomy. The first reports of robotic-assisted minimally invasive esophagectomy were published in the early 2000s. The surgical robot offers several advantages: multiple arms which allow the surgeon to assist himself and furthermore provide superior instrument dexterity and stable high-definition and stereoscopic visualization. This chapter outlines the evolution of esophagectomy from open to minimally invasive robotic technique and details the technical aspects of robotic Ivor Lewis Esophagogastrectomy.

Due to the difficulties in the intra-thoracic esophagogastric anastomosis creation, totally minimally invasive Ivor Lewis esophagectomy (MIE) did not encountered a large diffusion, preferring hybrid techniques or cervical anastomosis. Robot-assisted minimally invasive esophagectomy (RAMIE) has gained popularity due to an easy reproducibility of the open anastomotic technique. In this feasibility study, we described the RAMIE technique introduced in our Center, providing innovative details for a mechanical end-to-end anastomosis. With patient in prone position, esophagectomy is conducted through the meso-esophagus plan. Robotic hand-sewn purse-string is realized above Azygos vein. A 4-cm thoracotomy in the fifth intercostal space is performed by enlarging the trocar incision. The tubulization is performed to create an access pouch for the introduction of the circular stapler. After the creation of the end-to-end anastomosis, the access pouch is resected and a robotic over-sewn is realized. From January 2020 until July 2020, ten patients were enrolled. No restriction in term of age, BMI, ASA grade or previous surgery were applied. Median operative time was 700 min. R0 resection was achieved in all cases with a good lymph node harvesting. No anastomotic leak or stricture were observed. One chyle leak was treated conservatively. Median length of stay was 8 days and 90 days mortality was 0%. This study evidenced how robotic surgery allowed us to perform the same anastomosis of our open technique with good oncological results and morbidity and length of stay comparable with our previous results. Of note, longer operative time has been recorded. Further studies after the completion of the learning curve are necessary to address more definite conclusions.

Once the decision has taken to resect an esophageal cancer, there are two main surgical minimally invasive esophagectomy (MIE) approaches: the transthoracic (the two-staged Ivor Lewis esophagectomy or three-staged McKeown esophagectomy) and the transhiatal esophagectomy (THE).

Minimally invasive esophagectomy is most frequently performed via a transthoracic, transhiatal, or three-hole approach. While the definitions of “minimally invasive esophagectomy” vary widely, most would consider the term to signify both a laparoscopic or robot-assisted laparoscopic abdominal approach combined with a thoracoscopic or robot-assisted thoracoscopic chest approach. Our preferred technique is a minimally invasive robot-assisted laparoscopic and thoracoscopic Ivor Lewis esophagectomy. In this chapter, we will present step by step EEA anastomosis in the chest and highlight other commonly performed strategies.

According to the annual report of the American Association of Poison Control, in the United States there were 195,715 cases (7.54%) of human exposure to cleaning substances (household) in 2016, which constitutes the second most common substance category that is involved in human poisoning. Twenty-nine of these cases resulted in death, whereas seventeen were suicide attempts. There is a bimodal distribution of the age of occurrence with the first peak presented in the pediatric (≤5-year-old) age group and the second peak in the adolescent and young adult (≥21-year-old) age group. More specifically, the vast majority of pediatric cases presenting with exposures to cleaning substances in the household was reported to reach 115,701. Children are more likely to ingest caustic substances accidentally, whereas adolescent/young adults frequently attempt intentional suicide that can result in more extensive injury.

The patient is positioned in prone position for right thoracoscopy. After a MIE Ivor Lewis resection, a hand-sewn esophago-gastrostomy is performed.

Background Minimally invasive Ivor Lewis esophagectomy (MIILE) provides better outcomes than open techniques, particularly in terms of post-operative recovery and pulmonary complications. However, in addition to requiring advanced technical skills, thoracoscopic access makes it hard to perform esophagogastric anastomosis safely, and the reported rates of anastomotic leak vary from 5 to 16%. Several minimally invasive esophago-gastric anastomotic techniques have been described, but to date strong evidence to support one technique over the others is still lacking. We herein report the technical details and preliminary results of a new robot-assisted hand-sewn esophago-gastric anastomosis technique. Methods From January 2018 to December 2020, 12 cases of laparoscopic/thoracoscopic Ivor Lewis esophagectomy with robot-assisted hand-sewn esophago-gastric anastomosis were performed. The gastric conduit was prepared and tailored taking care of vascularization with a complete resection of the gastric fundus. The anastomosis consisted of a robot-assisted, hand-sewn four layers of absorbable monofilament running barbed suture (V-lock). The posterior outer layer incorporated the gastric and esophageal staple lines. Results The post-operative course was uneventful in nine cases. Two patients developed chyloperitoneum, one patient a Sars-Cov-2 infection, and one patient a late anastomotic stricture. In all cases, there were no anastomotic leaks or delayed gastric conduit emptying. The median post-operative stay was 13 days (min 7, max 37 days); the longest in-hospital stay was recorded in patients who developed chyloperitoneum. Conclusion Despite the small series, we believe that our technique looks to be promising, safe, and reproducible. Some key points may be useful to guarantee a low complications rate after MIILE, particularly regarding anastomotic leaks and delayed emptying: the resection of the gastric fundus, the use of robot assistance, the incorporation of the staple lines in the posterior aspect of the anastomosis, and the use of barbed suture. Further cases are needed to validate the preliminary, but very encouraging, results.

There are two important Minimally Invasive Esophagectomy approaches, the three-stage McKeown procedure with cervical anastomosis and the two-stage Ivor Lewis procedure with intrathoracic anastomosis. To perform these procedures, a profound knowledge of the surgical anatomy of the mediastinum and esophagus is paramount. Subcarinal anatomy of esophagus is in many aspects different from the supracarinal anatomy with important implications for the dissection of distal esophageal and Gastroesophageal Junction tumors. In this chapter the subcarinal anatomy is depicted.

Background Oncological esophageal surgery has evolved significantly in the last decades. From open esophagectomy over (hybrid) minimally invasive surgery, nowadays, robot-assisted minimally invasive esophagectomy (RAMIE) approaches are applied. Current techniques require an analysis of possible advantages and disadvantages indicating the direction towards a novel gold standard. Methods Robot-assisted Ivor Lewis esophagectomies, performed in the period from April 2017 to June 2019 in five German centers (Berlin, Cologne, Hamburg, Kiel, Mainz), were included in this study. Pre-, intra-, and postoperative parameters were assessed. Cases were grouped for hybrid (H-RAMIE) versus totally robot-assisted (T-RAMIE) approaches. Postoperative parameters and complications were compared using risk ratios. Results A total of 175 operations were performed as T-RAMIE and 67 as H-RAMIE. Patient age (median age 62 years) and sex (83.1% male) were similarly distributed in both groups. Median duration of esophagectomy was significantly lower in the T-RAMIE group (385 versus 427 min, p < 0.001). The risks of “overall morbidity” (32.0 versus 47.8%; risk ratio [RR], 95% confidence interval (CI): 1.5, 1.1–2.1; p = 0.026), “anastomotic leak” (10.3 versus 22.4%; RR, CI: 2.2, 1.2–4.1; p = 0.020), and “respiratory failure” (1.1 versus 7.5%; RR, CI: 6.5, 1.3–32.9; p = 0.019) were significantly higher in case of H-RAMIE. Conclusions In the five participating German centers, T-RAMIE was the preferred procedure (72.3% of operations). In comparison to H-RAMIE, T-RAMIE was associated with a significantly reduced risk of postoperative morbidity, anastomotic leak, and respiratory failure as well as a significantly reduced time necessary for esophagectomy.

The oesophagus is dissected free above the carina in order to create enough space for a side-to-side anastomosis.

There are many approaches to esophagectomy for esophageal cancer, with each offering unique advantages and disadvantages depending on cancer location, patient factors, and surgeon experience and preference. Our institution has favored the minimally invasive approach to an Ivor Lewis esophagectomy beginning with a laparoscopic intra-abdominal mobilization followed by a video-assisted thoracoscopic surgery (VATS) approach for the intrathoracic mobilization and anastomosis. This technique is particularly suited for mid to lower esophageal cancers, and while traditional teaching has been that intra-thoracic anastomoses that leak can have catastrophic complications, modern adjunctive strategies can mitigate the consequences when anastomotic leaks do occur (albeit rare). In addition, the minimally invasive technique is associated with reduced morbidity and equivalent long-term survival compared to open esophagectomy. In this chapter, we discuss in detail the technical aspects of a minimally invasive Ivor Lewis esophagectomy (Video 2.1).

After a MIE Ivor Lewis procedure, an end-to-side esophago-gastrostomy is performed using a double Endoloop system. The key steps to perform this intrathoracic esophago-gastric anastomosis are depicted.

Simple Summary Anastomotic leak is the most dangerous complication occurring after esophagectomy and its relationship with inadequate visceral perfusion is widely recognized. Currently, the adequate perfusion of the gastric conduit is intraoperatively assessed by surgeons using subjective indicators (e.g., serosal color or pulsatile flow of vessels). During the last decades, several innovative optical techniques based on the interaction of light with tissue have been developed to monitor perfusion in esophagogastric surgery. However, these innovative approaches are characterized by a lack of video rate and reproducibility. They also provide operator-dependent results and lengthen the surgical workflow. Single Snapshot imaging of Optical Properties (SSOP) is an optical technique, which can overcome such limitations, providing quantitative information on the optical properties of biological tissues over a large field of view. It is the first study to demonstrate the accuracy of SSOP in the quantification of serosal StO2% in a porcine gastric conduit model. Abstract Anastomotic leakage (AL) is a serious complication occurring after esophagectomy. The current knowledge suggests that inadequate intraoperative perfusion in the anastomotic site contributes to an increase in the AL rate. Presently, clinical estimation undertaken by surgeons is not accurate and new technology is necessary to improve the intraoperative assessment of tissue oxygenation. In the present study, we demonstrate the application of a novel optical technology, namely Single Snapshot imaging of Optical Properties (SSOP), used to quantify StO2% in an open surgery experimental gastric conduit (GC) model. After the creation of a gastric conduit, local StO2% was measured with a preclinical SSOP system for 60 min in the antrum (ROI-A), corpus (ROI-C), and fundus (ROI-F). The removed region (ROI-R) acted as ischemic control. ROI-R had statistically significant lower StO2% when compared to all other ROIs at T15, T30, T45, and T60 (p < 0.0001). Local capillary lactates (LCLs) and StO2% correlation was statistically significant (R = −0.8439, 95% CI −0.9367 to −0.6407, p < 0.0001). Finally, SSOP could discriminate resected from perfused regions and ROI-A from ROI-F (the future anastomotic site). In conclusion, SSOP could well be a suitable technology to assess intraoperative perfusion of GC, providing consistent StO2% quantification and ROIs discrimination.

The anastomosis will be performed after complete mediastinal lymphadenectomy and mobilization of the esophagus. The abdominal lymphadenectomy and gastric tube creation have been performed earlier, by laparoscopy during the abdominal phase.

Esophageal carcinoma is the eighth most common cancer worldwide and the sixth most common cause of cancer-related death. Although squamous cell carcinoma (ESCC) represents the most common histology, in the United States and many other Western countries, the incidence rate of adenocarcinoma (EAC) now exceeds that of ESCC, and this is expected to only increase. Most EACs affect the lower third of the esophagus and gastroesophageal junction, and since the location of these tumors generally does not require removal of the entire esophagus, partial esophagectomy with intrathoracic anastomosis is increasingly favored among thoracic surgeons. Furthermore, the majority of surgically resectable patients present with locoregionally advanced stage requiring induction chemo- or chemoradiation therapy up front, which may lessen the reliability of the stomach conduit for anastomosis in the neck. Therefore, over the last decade, there has been a shift in the approach to esophagectomy away from transhiatal and three-hole (McKeown) techniques toward a transthoracic (Ivor Lewis) approach. Furthermore, this trend has been observed for both open esophagectomy and minimally invasive esophagectomy (MIE). Because performance of MIE with intrathoracic anastomosis is technically complex, particularly with respect to the performance of the anastomosis, the advent of robotics has delivered greater dexterity with a minimally invasive approach and may overcome some of the technical limitations inherent in “straight stick” laparoscopic/thoracoscopic approaches. A recent consensus statement recommended standardizing the nomenclature for esophagectomy according to procedure and approach; therefore, robotic-assisted Ivor Lewis esophagectomy is referred to as ILER.

This chapter details briefly the history and evolution of esophagectomy. The transition to minimally invasive methods, advantages, disadvantages, and the emergence of robot-assisted esophagectomies are detailed. The early reports of robot-assisted esophagectomy have incomplete documentation; however, the history of its evolution to totally robotic Ivor Lewis esophagectomy has been detailed. The indications, preoperative planning, anesthetic concerns, operative technique for performing this procedure safely (including a video link and intraoperative pictures), postoperative care, and complications are discussed. A comprehensive review of the published outcomes, costs incurred, and “resident training” for this procedure are provided.
