Background/Objectives: Esophagectomy represents a major oncological operation due to the surgical involvement of both the abdominal and thoracic cavities. The minimally invasive technique has been developed to minimize the operative impact on patients undergoing esophageal resections, often presenting with nutritional deterioration and poor functional reserves. Methods: The present article provides an illustrative description of the total minimally invasive (laparo-thoracoscopic) Ivor Lewis esophagectomy for cancer integrated with complementary components of perioperative clinical management. This standardized surgical technique of two-field esophagectomy (i.e., laparoscopy and thoracoscopy) was depicted based on the experience of a tertiary center for esophageal cancer care with more than 1500 cases operated on, and in accordance with the SUPER reporting guidelines. Results and conclusions: The accomplishment of the following descriptive and illustrative content allowed the development of remarks on the strengths and possible flaws of this specific procedure, providing a measurable opportunity to absorb technical details of the most widespread surgical resection for esophageal cancer worldwide.

Background: Frailty, rather than age, is associated with postoperative morbidity and mortality. We sought to determine whether preoperative frailty as defined by a novel scoring system could predict the outcomes among older patients undergoing esophagectomy. Methods: We identified patients 65 years or older who underwent esophagectomy between 2011 and 2021 at our institution. Frailty was assessed using the MSK-FI, which consists of 1 component related to functional status and 10 medical comorbidities. We used a multivariable logistic regression model to test for the associations between frailty and short-term outcomes, with continuous frailty score as the predictor and additionally adjusted for age and Eastern Cooperative Oncology Group performance status. Results: In total, 447 patients were included in the analysis (median age of 71 years [interquartile range, 68–75]). Most of the patients underwent neoadjuvant treatment (81%), an Ivor Lewis esophagectomy (86%), and minimally invasive surgery (55%). A total of 22 patients (4.9%) died within 90 days of surgery, 144 (32%) had a major complication, 81 (19%) were readmitted, and 31 (7.2%) were discharged to a facility. Of the patients who died within 90 days, 19 had a major complication, yielding a failure-to-rescue rate of 13%. The risk of 30-day major complications (OR, 1.24 [95% CI, 1.09–1.41]; p = 0.001), readmissions (OR, 1.31 [95% CI, 1.13–1.52]; p < 0.001), and discharge to a facility (OR, 1.86 [95% CI, 1.49–2.37]; p < 0.001) increased with increasing frailty. Frailty and 90-day mortality were not associated. Conclusions: Frailty assessment during surgery decision-making can identify patients with a high risk of morbidity. Full article

Background: The global shift from open esophagectomy (OE) to minimally invasive esophagectomy (MIE) for treating esophageal cancer is well-established. Recent data indicate that transitioning from hybrid minimally invasive esophagectomy (hMIE) to total minimally invasive esophagectomy (tMIE) can be challenging due to concerns about higher leakage rates and lower lymph node counts, especially at the beginning of the learning curve. This study aimed to demonstrate that a safe transition from OE to tMIE for cancer is possible using process management methodology. Methods: A step-change approach was adopted in process management planning, with hMIE serving as an intermediate step between OE and tMIE. This single-center, case–control study included 150 patients who underwent the Ivor Lewis procedure with curative intent for esophageal cancer. Among these patients, 50 underwent OE, 50 hMIE (laparoscopic procedure followed by conventional right thoracotomy), and 50 tMIE (laparoscopic and thoracoscopic approach). A preceptored training scheme was implemented during execution, and treatment results were monitored and controlled to ensure a safe transition. Results: During the transition, the tMIE group was not worse than the hMIE and OE groups regarding operation duration (p = 0.135), overall postoperative complications (p = 0.020), anastomotic leakage rates (p = 0.773), 30-day mortality (p = 1.0), and oncological outcomes (based on R status (p = 0.628) and 2-year survival (p = 0.967)). Additionally, the tMIE group showed superior results in terms of major postoperative pulmonary complications (p = 0.004) and ICU stay duration (p < 0.001). Conclusions: Utilizing managerial methodology and practice in surgery, as a bridge between interdisciplinary and transdisciplinary approaches, demonstrated that transitioning from OE to tMIE, with hMIE as an intermediate step, is safe and feasible without compromising outcomes.

Hyperspectral imaging (HSI) is a non-invasive and contactless technique that enables the real-time acquisition of comprehensive information on tissue within the surgical field. In this pilot study, we investigated whether a new HSI system for minimally-invasive surgery, TIVITA^® Mini (HSI-MIS), provides reliable insights into tissue perfusion of the proximal and distal esophagogastric anastomotic sites during 21 laparoscopic/thoracoscopic or robotic Ivor Lewis esophagectomies of patients with cancer to minimize the risk of dreaded anastomotic insufficiency. In this pioneering investigation, physiological tissue parameters were derived from HSI measurements of the proximal site of the anastomosis (esophageal stump) and the distal site of the anastomosis (tip of the gastric conduit) during the thoracic phase of the procedure. Tissue oxygenation (StO₂), Near Infrared Perfusion Index (NIR-PI), and Tissue Water Index (TWI) showed similar median values at both anastomotic sites. Significant differences were observed only for NIR-PI (median: 76.5 vs. 63.9; p = 0.012) at the distal site (gastric conduit) compared to our previous study using an HSI system for open surgery. For all 21 patients, reliable and informative measurements were attainable, confirming the feasibility of HSI-MIS to assess anastomotic viability. Further studies on the added benefit of this new technique aiming to reduce anastomotic insufficiency are warranted. Full article

In recent decades, robotic-assisted minimally invasive esophagectomy (RAMIE) has been increasingly adopted for patients with esophageal cancer (EC) or cancer of the gastroesophageal junction (GEJ). However, concerns regarding its costs compared to conventional minimally invasive esophagectomy (MIE) have emerged. This study examined outcomes and costs of RAMIE versus total MIE in 128 patients who underwent Ivor Lewis esophagectomy for EC/GEJ at our department between 2017 and 2021. Surgical costs were higher for RAMIE (EUR 12,370 vs. EUR 10,059, p < 0.001). Yet, median daily (EUR 2023 vs. EUR 1818, p = 0.246) and total costs (EUR 30,510 vs. EUR 29,180, p = 0.460) were comparable. RAMIE showed a lower incidence of postoperative pneumonia (8% vs. 25%, p = 0.029) and a trend towards shorter hospital stays (15 vs. 17 days, p = 0.205), which may have equalized total costs. Factors independently associated with higher costs included readmission to the intensive care unit (hazard ratio [HR] = 7.0), length of stay (HR = 13.5), anastomotic leak (HR = 17.0), and postoperative pneumonia (HR = 5.4). In conclusion, RAMIE does not impose an additional financial burden. This suggests that RAMIE may be considered as a valid alternative approach for esophagectomy. Attention to typical cost factors can enhance postoperative care across surgical methods. Full article

Advancements in perioperative care have improved postoperative morbidity and recovery after esophagectomy. The direct start of oral intake can also enhance short-term outcomes following minimally invasive Ivor Lewis esophagectomy (MIE-IL). Subsequently, short-term outcomes may affect long-term survival. This planned sub-study of the NUTRIENT II trial, a multicenter randomized controlled trial, investigated the long-term survival of direct versus delayed oral feeding following MIE-IL. The outcomes included 3- and 5-year overall survival (OS) and disease-free survival (DFS), and the influence of complications and caloric intake on OS. After excluding cases of 90-day mortality, 145 participants were analyzed. Of these, 63 patients (43.4%) received direct oral feeding. At 3 years, OS was significantly better in the direct oral feeding group (p = 0.027), but not at 5 years (p = 0.115). Moreover, 5-year DFS was significantly better in the direct oral feeding group (p = 0.047) and a trend towards improved DFS was shown at 3 years (p = 0.079). Postoperative complications and caloric intake on day 5 did not impact OS. The results of this study show a tendency of improved 3-year OS and 5-year DFS, suggesting a potential long-term survival benefit in patients receiving direct oral feeding after esophagectomy. However, the findings should be further explored in larger future trials. Full article

Background: Postesophagectomy diaphragmatic prolapse (PDP) is a major complication after esophagectomy with significant mortality and morbidity. However, in the current literature, treatment and outcomes are not evaluated for patients undergoing an Ivor Lewis Robot-assisted minimally invasive esophagectomy (IL-RAMIE). The aim of this study is to evaluate the incidence of PDP after IL-RAMIE. Moreover, the study aims to determine whether using a minimally invasive approach in the management of PDP after an IL-RAMIE procedure is safe and feasible. Materials and Methods: This study includes all patients who received an IL-RAMIE at our high-volume center (>200 esophagectomies/year) between April 2017 and December 2022 and developed PDP. The analysis focuses on time to prolapse, symptoms, treatment, surgical method, and recurrence rates of these patients. Results: A total of 185 patients underwent an IL-RAMIE at our hospital. Eleven patients (5.9%) developed PDP. Patients presented with PDP after a medium time of 241 days with symptoms like reflux, nausea, vomiting, and pain. One-third of these patients did not suffer from any symptoms. In all cases, a CT scan was performed in which the colon transversum always presented as the herniated organ. In one patient, prolapse of the small intestine, pancreas, and greater omentum also occurred. A total of 91% of these patients received a revisional surgery in a minimally invasive manner with a mean hospital stay of 12 days. In four patients, PDP recurred (36%) after 13, 114, 119 and 237 days, respectively. Conclusion: This study shows that a minimally invasive approach in repositioning PDP is a safe and effective option after IL-RAMIE. Full article

This retrospective analysis aimed to assess and compare the short-term perioperative outcomes and morbidity of hybrid and full-Robotic-Assisted Minimally Invasive Esophagectomy (RAMIE) surgical techniques. A total of 168 robotic-assisted Ivor Lewis esophagectomy procedures performed at Muenster University Hospital were included in the study, with 63 cases in the hybrid group and 105 cases in the full-robotic group. Demographic factors, comorbidities, and tumor stages showed no significant differences between the two groups. However, the full-RAMIE technique demonstrated superiority in terms of overall operative time, postoperative pain levels, and patient morphine consumption. Additionally, the full-RAMIE group exhibited better perioperative outcomes, with significantly shorter ICU stays and fewer occurrences of pneumonias and severe complications. While there was a trend favoring the full-RAMIE technique in terms of severe postoperative complications and anastomotic insufficiencies, further research is required to establish it as the gold standard surgical technique for Ivor Lewis esophagectomy.

Background: Even though minimally invasive esophagectomy is a safe and oncologically effective procedure, several authors have reported an increased risk of postoperative hiatal hernia (PHH). This study evaluates the incidence and risk factors of PHH after hybrid minimally invasive (HMIE) versus open esophagectomy (OE). Methods: A retrospective single-center analysis was performed on patients who underwent Ivor Lewis esophagectomy between January 2009 and April 2018. Computed tomography scans and patient files were reviewed to identify the PHH. Results: 306 patients were included (152 HMIE; 154 OE). Of these, 23 patients (8%) developed PHH. Most patients (13/23, 57%) were asymptomatic at the time of diagnosis and only 4 patients (17%) presented in an emergency setting with incarceration. The rate of PHH was significantly higher after HMIE compared to OE (13.8% vs. 1.3%, p < 0.001). No other risk factors for the development of PHH were identified in uni- or multi-variate analysis. Surgical repair of PHH was performed in 19/23 patients (83%). The recurrence rate of PHH after surgical repair was 32% (6/19 patients). Conclusions: The development of PHH is a relevant complication after hybrid minimally invasive esophagectomy. Although most patients are asymptomatic, surgical repair is recommended to avoid incarceration with potentially fatal outcomes. Innovative techniques for the prevention and repair of PHH are urgently needed. Full article

Background: Complications arising following minimally invasive Ivor Lewis esophagectomy often result from inadequate enteral nutrition, highlighting the need for proactive measures to prevent such issues. One approach involves identifying high-risk cases prone to complications and implementing percutaneous endoscopic jejunostomy (PEJ) tube placement during esophageal resection to ensure timely enteral nutrition. Methods: In this single-center, retrospective cohort study, we examined patients who underwent minimally invasive esophagectomy for esophageal cancer at a high-volume center. The dataset encompassed demographic information, comorbidities, laboratory parameters, and intraoperative details. Our center utilized the EndoVac system pre-emptively to safeguard the anastomosis from harmful secretions and to enhance local oxygen partial pressure. All patients received pre-emptive EndoVac therapy and underwent esophagogastroduodenoscopy in the early postoperative days. The need for multiple postoperative EndoVac cycles indicated complications, including anastomotic insufficiency and subsequent requirement for a PEJ. The primary objectives were identifying predictive factors for anastomotic insufficiency and the need for multi-cycle EndoVac therapy, quantifying their effects, and assessing the likelihood of postoperative complications. Results: 149 patients who underwent minimally invasive or hybrid Ivor Lewis esophagectomy were analyzed and 21 perioperative and demographic features were evaluated. Postoperative complications were associated with the body mass index (BMI) category, the use of blood pressure medication, and surgery duration. Anastomotic insufficiency as a specific complication was correlated with BMI and the Charlson comorbidity index. The odds ratio of being in the high-risk group significantly increased with higher BMI (OR = 1.074, p = 0.048) and longer surgery duration (OR = 1.005, p = 0.004). Conclusions: Based on our findings, high BMI and longer surgery duration are potential risk factors for postoperative complications following minimally invasive esophagectomy. Identifying such factors can aid in pre-emptively addressing nutritional challenges and reducing the incidence of complications in high-risk patients. Full article

While the sentinel lymph node concept is routinely applied in other surgical fields, no established and valid modality for lymph node mapping for esophageal cancer surgery currently exists. Near-infrared light fluorescence (NIR) using indocyanine green (ICG) has been recently proven to be a safe technology for peritumoral injection and consecutive lymph node mapping in small surgical cohorts, mostly without the usage of robotic technology. The aim of this study was to identify the lymphatic drainage pattern of esophageal cancer during highly standardized RAMIE and to correlate the intraoperative images with the histopathological dissemination of lymphatic metastases. Patients with clinically advanced stage squamous cell carcinoma or adenocarcinoma of the esophagus undergoing a RAMIE at our Center of Excellence for Surgery of the Upper Gastrointestinal Tract were prospectively included in this study. Patients were admitted on the day prior to surgery, and an additional EGD with endoscopic injection of the ICG solution around the tumor was performed. Intraoperative imaging procedures were performed using the Stryker 1688 or the FIREFLY fluorescence imaging system, and resected lymph nodes were sent to pathology. A total of 20 patients were included in the study, and feasibility and safety for the application of NIR using ICG during RAMIE were shown. NIR imaging to detect lymph node metastases can be safely performed during RAMIE. Further analyses in our center will focus on pathological analyses of ICG-positive tissue and quantification using artificial intelligence tools with a correlation of long-term follow-up data.

Background and Objectives: Though widely used, only limited data is available that shows the superiority of hybrid minimally-invasive esophagectomy (HMIE) compared to open esophagectomy (OE). The present study aimed to analyze postoperative morbidity, mortality, and compare lengths of hospital stay. Materials and Methods: A total of 174 patients underwent Ivor Lewis esophagectomy in our surgical department, of which we retrospectively created a matched population of one hundred (HMIE n = 50, OE n = 50). Morbidity and mortality data was categorized, analyzed, and risk factor analyzed for complications. Results: The oncological results were found to be comparable in both groups. A median of 23.5 lymphnodes were harvested during OE, and 21.0 during HMIE. Negative tumor margins were achieved in 98% of OE and 100% of HMIE. In-hospital mortality rate showed no significant difference between techniques (OE 14.0%, HMIE 4.0%, p = 0.160). Hospital (OE Median 23.00 days, HMIE 16.50 days, p = 0.004) and ICU stay (OE 5.50 days, HMIE 3.00 days, p = 0.003) was significantly shorter after HMIE. The overall complication rate was 50%, but complications in general (OE 70.00%, HMIE 30%, p < 0.001) as well as severe complications (Clavien Dindo ≥ III: HMIE 16.0%, OE 48.0%, p < 0.001) were significantly more common after OE. In multivariate stepwise regressions the influence of OE proved to be independent for said outcomes. We observed more pulmonary complications in the OE group (46%) compared to HMIE patients (26%). This difference was statistically significant after adjustment for sex, age, BMI, ASA classification, histology, neoadjuvant treatment or not, smoking status, cardiac comorbidities, diabetes mellitus, and alcohol abuse (p = 0.019). Conclusions: HMIE is a feasible technique that significantly decreases morbidity, while ensuring equivalently good oncological resection compared to OE. HMIE should be performed whenever applicable for patients and surgeons. Full article

Introduction: The value of C-reactive protein (CRP) as a predictor of anastomotic leakage (AL) after esophagectomy has been addressed by numerous studies. Despite its increasing application, robotic esophagectomy (RAMIE) has not been considered separately yet in this context. We, therefore, aimed to evaluate the predictive value of CRP in RAMIE. Material and Methods: Patients undergoing RAMIE or completely open esophagectomy (OE) at our University Center were included. Clinical data, CRP- and Procalcitonin (PCT)-values were retrieved from a prospectively maintained database and evaluated for their predictive value for subsequent postoperative infectious complications (PIC) (AL, gastric conduit leakage or necrosis, pneumonia, empyema). Results: Three hundred and five patients (RAMIE: 160, OE: 145) were analyzed. PIC were noted in 91 patients on postoperative day (POD) 10 and 123 patients on POD 30, respectively. Median POD of diagnosis of PIC was POD 8. Post-operative CRP-values in the robotic-group peaked one and two days later, respectively, and converged from POD 5 onward compared to the open-group. In the group with PIC, CRP-levels in the robotic-group were initially lower and started to differ significantly from POD 3 onward. In the open-group, increases were already noticed from POD 3 on. Procalcitonin levels did not differ. Best Receiver operating curve (ROC)-results were on POD 4, highest negative predictive values at POD 5 (RAMIE) and POD 4 (OE) with cut-off values of 70 mg/L and 88.3 mg/L, respectively. Conclusion: Post-operative CRP is a good negative predictor for PIC, after both RAMIE and OE. After RAMIE, CRP peaks later with a lower cut-off value. Full article

With the evolution of minimally invasive esophagectomy (MIE) and robot-assisted minimally invasive esophagectomy (RAMIE), questions remain regarding the benefits and indications of these methods. Given that set indications do not exist, this article aims first to review the reported outcomes of MIE, RAMIE, and open esophagectomy. Then, considerations based on the reported outcomes are discussed to guide surgeons in selecting the best approach. MIE and RAMIE offer the potential to improve outcomes for esophagectomy patients; however, surgeon experience as well as individual patient factors play important roles when deciding upon the surgical approach.

Transthoracic esophagectomy is currently the predominant curative treatment option for resectable esophageal adenocarcinoma. The majority of carcinomas present as locally advanced tumors requiring multimodal strategies with either neoadjuvant chemoradiotherapy or perioperative chemotherapy alone. Minimally invasive, including robotic, techniques are increasingly applied with a broad spectrum of technical variations existing for the oncological resection as well as gastric reconstruction. At the present, intrathoracic esophagogastrostomy is the preferred technique of reconstruction (Ivor Lewis esophagectomy). With standardized surgical procedures, a complete resection of the primary tumor can be achieved in almost 95% of patients. Even in expert centers, postoperative morbidity remains high, with an overall complication rate of 50–60%, whereas 30- and 90-day mortality are reported to be <2% and <6%, respectively. Due to the complexity of transthoracic esophagetomy and its associated morbidity, esophageal surgery is recommended to be performed in specialized centers with an appropriate caseload yet to be defined. In order to reduce postoperative morbidity, the selection of patients, preoperative rehabilitation and postoperative fast-track concepts are feasible strategies of perioperative management. Future directives aim to further centralize esophageal services, to individualize surgical treatment for high-risk patients and to implement intraoperative imaging modalities modifying the oncological extent of resection and facilitating surgical reconstruction.
