The effect of postoperative complications on survival of patients after minimally invasive esophagectomy for esophageal cancer

Prognostic factors for patients with pathologic T1-T2N+ esophageal squamous cell carcinoma: A retrospective study with external validation

BACKGROUND

Lymph node metastasis is significantly associated with a worse prognosis in patients with localized early-stage esophageal squamous cell carcinoma. This study aimed to explore the prognostic factors and develop a nomogram for predicting survival in patients with pathologic T1-2N+ esophageal squamous cell carcinoma.

METHODS

Between 2014 and 2022, patients with pT1-2N+ esophageal squamous cell carcinoma who underwent esophagectomy with lymphadenectomy at 2 institutes were reviewed and assigned to training and external validation cohorts. Independent prognostic factors were identified via univariate and multivariate Cox regression analyses. The nomogram model was developed and evaluated by the area under the receiver operating characteristic curve and calibration curve.

RESULTS

In total, 268 patients with a median age of 65 years (range, 40-82) were included and assigned to training (n = 190) and external validation (n = 78) cohorts. The Cox proportional hazards model demonstrated that body mass index (P = .031), surgical approach (P < .001), T stage (P = .015), and Clavien-Dindo classification (P < .001) were independent prognostic factors in the training cohort. The nomogram showed good discrimination, with an area under the receiver operating characteristic curve for 1-year, 3-year, and 5-year of 0.810, 0.789, and 0.809 in the training cohort and 0.782, 0.679, and 0.698 in the validation cohort. The calibration curve showed that the predicted survival probability was in good agreement with the actual survival probability.

CONCLUSION

Lower body mass index, left surgical approach, T2 stage, and Clavien-Dindo classification grade III to V were related to worse prognosis in patients with pT1-T2N+ esophageal squamous cell carcinoma. The developed nomogram may predict individual survival accurately.

Long-Term Impact of Severe Postoperative Complications after Esophagectomy for Cancer: Individual Patient Data Meta-Analysis

BACKGROUND

Severe postoperative complications (SPCs) may occur after curative esophagectomy for cancer and are associated with prolonged hospital stay, augmented costs, and increased in-hospital mortality. However, the effect of SPCs on survival after esophagectomy is uncertain.

AIM

To assess the impact of severe postoperative complications (SPCs) on long-term survival following curative esophagectomy for cancer, we conducted a systematic search of PubMed, MEDLINE, Scopus, and Web of Science databases up to December 2023. The included studies examined the relationship between SPCs and survival outcomes, defining SPCs as Clavien-Dindo grade > 3. The primary outcome measure was long-term overall survival (OS). We used restricted mean survival time difference (RMSTD) and 95% confidence intervals (CIs) to calculate pooled effect sizes. Additionally, we applied the GRADE methodology to evaluate the certainty of the evidence.

RESULTS

Ten studies (2181 patients) were included. SPCs were reported in 651 (29.8%) patients. The RMSTD overall survival analysis shows that at 60-month follow-up, patients experiencing SPCs lived for 8.6 months (95% Cis -12.5, -4.7; p < 0.001) less, on average, compared with no-SPC patients. No differences were found for 60-month follow-up disease-free survival (-4.6 months, 95% CIs -11.9, 1.9; p = 0.17) and cancer-specific survival (-6.8 months, 95% CIs -11.9, 1.7; p = 0.21). The GRADE certainty of this evidence ranged from low to very low.

CONCLUSIONS

This study suggests a statistically significant detrimental effect of SPCs on OS in patients undergoing curative esophagectomy for cancer. Also, a clinical trend toward reduced CSS and DFS was perceived.

The association between postoperative complications and long-term survival after esophagectomy: a multicenter cohort study

Conflicting results are reported on the association between post-esophagectomy complications and long-term survival. This multicenter study assesses the association between complications after an esophagectomy and long-term overall survival. Five Dutch high-volume centers collected data from consecutive patients undergoing esophagectomy between 2010 and 2016 and merged these with long-term survival data from the Netherlands Cancer Registry. Exclusion criteria were non-curative resections and 90-day mortality, among others. Primary outcome was overall survival related to the presence of a postoperative complication in general. Secondary outcomes analyzed the presence of anastomotic leakage and cardiopulmonary complications. Propensity score matching was performed and the outcomes were analyzed via Log-Rank test and Kaplan Meier analysis. Among the 1225 patients included, a complicated course occurred in 719 patients (59.0%). After matching for baseline characteristics, 455 pairs were successfully balanced. Patients with an uncomplicated postoperative course had a 5-year overall survival of 51.7% versus 44.4% in patients with complications (P = 0.011). Anastomotic leakage occurred in 18.4% (n = 226), and in 208 matched pairs, it was shown that the 5-year overall survival was 57.2% in patients without anastomotic leakage versus 44.0% in patients with anastomotic leakage (P = 0.005). Overall cardiopulmonary complication rate was 37.1% (n = 454), and in 363 matched pairs, the 5-year overall survival was 52.1% in patients without cardiopulmonary complications versus 45.3% in patients with cardiopulmonary complications (P = 0.019). Overall postoperative complication rate, anastomotic leakage, and cardiopulmonary complications were associated with a decreased long-term survival after an esophagectomy. Efforts to reduce complications might further improve the overall survival for patients treated for esophageal carcinoma.

Inflammatory and Nutritional Status Influences Outcomes of Minimally Invasive Esophagectomy

INTRODUCTION

The potential association between severe postoperative complications (SPC) and the oncological outcomes of esophageal squamous cell carcinoma (ESCC) patients according to the different Naples Prognostic Score (NPS) of the inflammatory nutritional status after minimally invasive esophagectomy (MIE) is unclear.

METHODS

Kaplan-Meier survival analysis was used to evaluate overall survival (OS) and disease-free survival (DFS) between with or without SPC (Clavien-Dindo grade ≥ III) in low NPS status (NPS = 0 or 1) and high NPS status (NPS = 2 or 3 or 4) patients. Cox multivariable analysis was carried out to analyze the various independent factors of OS and DFS, and a nomogram based on SPC was established.

RESULTS

A total of 20.7% (125/604) ESCC patients developed SPC after MIE. Patients with SPC exhibited poor 5-year OS and DFS compared to those without SPC (all P < 0.001). Further analysis revealed that SPC significantly reduced OS and DFS in patients with high NPS status (all P < 0.001) but had little effect on the prognosis of patients with low NPS status (all P > 0.05). Multivariable Cox analysis revealed that SPC could be an independent influence indicator for OS and DFS in patients with high NPS status. Therefore, a novel nomogram combining SPC and tumor-node-metastasis (TNM) staging has been developed, which was found to be relatively more accurate in predicting OS and DFS than TNM staging alone.

CONCLUSION

Severe complications can adversely affect the long-term oncological outcome of ESCC patients with high systemic inflammatory response and malnutrition after MIE.

Postoperative respiratory morbidity can adversely affect prognosis in thoracoscopic esophagectomy for esophageal cancer: a retrospective study

BACKGROUND

Esophagectomy for esophageal cancer is associated with frequent respiratory morbidities, which may deteriorate postoperative survival outcomes. Thoracoscopic esophagectomy (TE) is less invasive and is associated with fewer respiratory morbidities than open esophagectomy. However, the relationship between post-TE respiratory morbidity and prognosis has not been well established.

METHODS

This study included 378 patients who underwent TE for esophageal cancer between May 2011 and November 2020. Patients were divided into two groups based on the presence of respiratory morbidity. Short-term and long-term outcomes of the groups were retrospectively compared.

RESULTS

Respiratory morbidity was significantly associated with heavy past smoking habits (Brinkman index, p = 0.0039), short duration of smoking cessation (p = 0.0012), worse American Society of Anesthesiologists physical status (p = 0.016), frequent cardiovascular comorbidities (p = 0.0085), and long hospital stay (p < 0.001). Respiratory morbidity significantly deteriorated overall survival (OS) (p = 0.011) and relapse-free survival (p = 0.062) and could be an independent prognostic factor for OS (hazard ratio = 1.90, 95% confidence interval = 1.093-3.311, p = 0.023) along with clinical stage.

CONCLUSION

Respiratory morbidity can adversely affect prognosis after TE. Various prophylaxes for respiratory morbidity are required to improve the short-term and long-term outcomes of TE for esophageal cancer.

Outcomes of elderly patients following thoracoscopic esophagectomy for esophageal cancer

PURPOSE

Thoracoscopic esophagectomy (TE) is widely used for esophageal cancer treatment. However, the short- and long-term outcomes of TE in older patients remain unknown. Thus, we investigated those outcomes as well as the effectivity of TE in this patient cohort.

METHODS

A total of 228 consecutive patients who underwent TE for esophageal cancer from 2002 to 2015 were included in the study and categorized into the elderly (≥ 75 years) and non-elderly (< 75 years) groups. The background was adjusted by propensity score matching. The short- and long-term outcomes were then compared between the two groups.

RESULTS

There was no difference in the short-term outcomes between the two groups. The elderly group had significantly lower overall survival (OS) and relapse-free survival (RFS) than the non-elderly group. When pulmonary complications occurred, the OS and RFS were significantly decreased in the elderly group but not in the non-elderly group. Without pulmonary complications, the OS and RFS in the elderly group did not differ from those in the non-elderly group. The multivariate analysis showed that pulmonary complications were independent poor prognostic factors for OS and RFS in the elderly group but not in the non-elderly group.

CONCLUSION

TE is safe and feasible for older patients. However, the OS and RFS of the elderly group were significantly worse than those of the non-elderly group, especially when pulmonary complications occurred. Therefore, perioperative management to prevent pulmonary complications is essential to improve the long-term outcomes of older patients receiving TE.

Old age and intense chemotherapy exacerbate negative prognostic impact of postoperative complication on survival in patients with esophageal cancer who received neoadjuvant therapy: a nationwide study from 85 Japanese esophageal centers

BACKGROUND

The prognostic impact of docetaxel, cisplatin, and 5-FU (DCF) reported in JCOG1109 was successfully validated using real-world data in patients < 75 years old. However, DCF was not reported to be beneficial in elderly patients with a relatively higher postoperative complication incidence. This study aimed to clarify the impact of postoperative complications on the prognosis of ESCC and the difference in the magnitude of the impact by age and regimen.

METHODS

Patients with esophageal squamous cell carcinoma (ESCC) who underwent subtotal esophagectomy at 85 authorized institutes were retrospectively reviewed from 2010 to 2015. The prognostic impact of postoperative anastomotic leakage (AL) and pneumonia on survival was evaluated. The prognostic value of the postoperative complications was assessed by stratifying patients according to age and neoadjuvant chemotherapy regimen.

RESULTS

Patients with AL, pneumonia, and infectious complications (ICs: a combination of pneumonia and AL) showed significantly worse overall survival (OS). IC served as a negative prognostic factor of OS and recurrence-free survival, and its negative prognostic impact was more evident in patients aged > 75 years. When the patients were further stratified by chemotherapeutic regimens, using the CF/IC(-) group as a reference, the DCF/IC (+) group showed significantly shorter OS in patients aged > 75 years with a hazard ratio (HR) of 2.551. The HR of the CF/IC (+) group was 1.503.

CONCLUSIONS

The negative impact of postoperative complications on survival was confirmed in this nationwide study. Furthermore, its magnitude was higher in elderly patients who received triplet chemotherapy.

Postoperative morbidity adversely impacts oncological prognosis after curative resection for hilar cholangiocarcinoma

BACKGROUND

Postoperative morbidity after curative resection for hilar cholangiocarcinoma (HCCA) is common; however, whether it has an impact on oncological prognosis is unknown.

AIM

To evaluate the influence of postoperative morbidity on tumor recurrence and mortality after curative resection for HCCA.

METHODS

Patients with recently diagnosed HCCA who had undergone curative resection between January 2010 and December 2017 at The First Affiliated Hospital of Army Medical University in China were enrolled. The independent risk factors for morbidity in the 30 d after surgery were investigated, and links between postoperative morbidity and patient characteristics and outcomes were assessed. Postoperative morbidities were divided into five grades based on the Clavien-Dindo classification, and major morbidities were defined as Clavien-Dindo ≥ 3. Univariate and multivariate Cox regression analyses were used to evaluate the risk factors for recurrence-free survival (RFS) and overall survival (OS).

RESULTS

Postoperative morbidity occurred in 146 out of 239 patients (61.1%). Multivariate logistic regression revealed that cirrhosis, intraoperative blood loss > 500 mL, diabetes mellitus, and obesity were independent risk factors. Postoperative morbidity was associated with decreased OS and RFS (OS: 18.0 mo vs 31.0 mo, respectively, P = 0.003; RFS: 16.0 mo vs 26.0 mo, respectively, P = 0.002). Multivariate Cox regression analysis indicated that postoperative morbidity was independently associated with decreased OS [hazard ratios (HR): 1.557, 95% confidence interval (CI): 1.119-2.167, P = 0.009] and RFS (HR: 1.535, 95%CI: 1.117-2.108, P = 0.008). Moreover, major morbidity was independently associated with decreased OS (HR: 2.175; 95%CI: 1.470-3.216, P < 0.001) and RFS (HR: 2.054; 95%CI: 1.400-3.014, P < 0.001) after curative resection for HCCA.

CONCLUSION

Postoperative morbidity (especially major morbidity) may be an independent risk factor for unfavorable prognosis in HCCA patients following curative resection.

Technique of robotic esophagectomy

Robotic surgery continues to grow in thoracic surgery, and currently plays an evolving role in esophagectomy. Robotic assisted minimally invasive esophagectomy (RAMIE) has continued to expand, with many institutions adapting the technique. As the overall experience continues to grow, new data is emerging in its support. We present our approach to this operation.

Effect of anastomotic leaks on long-term survival after oesophagectomy for oesophageal cancer: systematic review and meta-analysis

INTRODUCTION

Long-term survival after curative surgery for oesophageal cancer surgery remains poor, and the prognostic impact of anastomotic leak (AL) remains unknown. A meta-analysis was conducted to investigate the impact of AL on long-term survival.

METHODS

A systematic electronic search for articles was performed for studies published between 2001 and 2020 evaluating the long-term oncological impact of AL. Meta-analysis was performed using the DerSimonian-Laird random-effects model to compute hazard ratios and 95% confidence intervals.

RESULTS

Nineteen studies met the inclusion criteria, yielding a total of 9885 patients. Long-term survival was significantly reduced after AL (HR: 1.79, 95% CI: 1.33-2.43). AL was associated with significantly reduced overall survival in studies within hospital volume Quintile 1 (HR: 1.35, 95% CI: 1.12-1.63) and Quintile 2 (HR: 1.83, 95% CI: 1.35-2.47). However, no significant association was found for studies within Quintile 3 (HR: 2.24, 95% CI: 0.85-5.88), Quintile 4 (HR: 2.59, 95% CI: 0.67-10.07), and Quintile 5 (HR: 1.29, 95% CI: 0.92-1.81). AL was significantly associated with poor long-term survival in patients with associated overall Clavien Dindo Grades 1-5 (HR: 2.17, 95% CI: 1.31-3.59) and severe Clavien Dindo Grades 3-5 (HR: 1.42, 95% CI: 1.14-1.78) complications.

CONCLUSIONS

AL has a negative prognostic impact on long-term survival after restorative resection of oesophageal cancers, particularly in low-volume centers. Future efforts must be focused on strategies to minimize the septic and immunological response to AL with early recognition and treatment thus reducing the impact on long-term survival.

Effects of Neoadjuvant Chemotherapy Toxicity and Postoperative Complications on Short-term and Long-term Outcomes After Curative Resection of Gastric Cancer

BACKGROUND

Whether neoadjuvant chemotherapy (NAC) increased the risk of postoperative morbidities for patients with locally advanced gastric cancer (GC) is unknown. Whether neoadjuvant chemotherapy toxicity (NCT) and postoperative complications (POCs) correlate with short-term and long-term outcomes also remains unclear. We aimed to evaluate the role of NAC on the development of POCs, as well as the impact of NCT and POCs on postoperative and oncologic outcomes in curatively resected GC treated with NAC.

METHODS

This study retrospectively reviewed 230 patients who underwent curative gastrectomy for locally advanced GC (clinically T3/4 or N+) after NAC between 2006 and 2016. Five hundred patients undergoing upfront and curative surgery were selected as a control group. After matching, the incidence of POCs was compared between two groups. In the NAC group, clinicopathological characteristics of patients who experienced POCs were compared to those who did not. Logistic and Cox multivariate regression analyses were used to examine factors associated with POCs, disease-free survival (DFS), and overall survival (OS).

RESULTS

Following matching, 230 and 230 patients treated with surgery plus NAC and upfront surgery remained, respectively. The incidence of POCs was 28.7% and 24.3%, respectively (p = 0.290). In the NAC group, NCT (OR [odds ratio] 22.968, 95% CI [confidence interval] 2.948-> 99, p = 0.003) and operation time (OR 1.006, 95% CI 1.001-1.011, p = 0.021) were independent predictive factors of POCs. NCT did not affect oncologic outcomes. The Cox regression model demonstrated that POCs were independently associated with worse DFS (HR [hazard ratio] 2.128, 95% CI 1.240-3.653, p = 0.006) but not OS for patients treated with NAC.

CONCLUSIONS

The administration of NAC is not associated with an elevated risk of POCs. For patients treated with NAC, NCT is an independent predictor of POCs, but does not affect oncologic outcomes. POCs is independently associated with worse DFS but not OS. NAC should be considered a safe approach in patients who have locally advanced GC. Strategies to minimize chemotherapy toxicity and postoperative morbidities associated with NAC are warranted.

The survival impact of postoperative complications after curative resection in patients with esophageal squamous cell carcinoma: propensity score-matching analysis

PURPOSE

The relationship between postoperative complications and long-term survival after surgery for esophageal squamous cell carcinoma (ESCC) is controversial.

METHOD

A total of 210 patients with ESCC who underwent subtotal esophagectomy with a reconstructed gastric tube were investigated according to the development of postoperative complications. The associations of age, gender, T and N factors, and pStage with grade 0-2 complications (NSC) and grade 3 and higher complications (SC) were compared by propensity score-matching analysis. Fifty-one pairs of NSC and SC groups were selected for the final analysis. We divided 102 patients between the NSC and SC groups or between the no pulmonary complication (NPC) and the pulmonary complication (PC) groups. The overall survival (OS) and disease-free survival (DFS) were determined by the Kaplan-Meier method and were compared by log-rank tests. Possible predictors of OS and DFS were subjected to univariate analysis and multivariate Cox proportional hazard regression analysis.

RESULTS

The propensity score matching revealed that the 5-year OS and DFS of the NSC group were not different from those of the SC group. However, the 5-year OS of the PC group was significantly worse than that of the NPC group, while no significant differences were observed in the DFS between the PC and NPC groups. In the multivariate analysis, UICC pStage, pulmonary complication, and American Heart Association (AHA) classification for OS and UICC pStage for DFS were significant prognostic factors.

CONCLUSION

The OS and DFS did not differ in patients with or without severe postoperative complications. However, postoperative pulmonary complications were independent predictors of poorer OS, but not DFS, in patients who underwent R0 resection for ESCC.

The Effect of Postoperative Complications After Minimally Invasive Esophagectomy on Long-term Survival: An International Multicenter Cohort Study

BACKGROUND

Esophagectomy is a technically challenging procedure, associated with significant morbidity. The introduction of minimally invasive esophagectomy (MIE) has reduced postoperative morbidity.

OBJECTIVE

Although the short-term effect on complications is increasingly being recognized, the impact on long-term survival remains unclear. This study aims to investigate the association between postoperative complications following MIE and long-term survival.

METHODS

Data were collected from the EsoBenchmark Collaborative composed by 13 high-volume, expert centers routinely performing MIE. Patients operated between June 1, 2011 and May 31, 2016 were included. Complications were graded using the Clavien-Dindo (CD) classification. To correct for short-term effects of postoperative complications on mortality, patients who died within 90 days postoperative were excluded. Primary endpoint was 5-year overall survival.

RESULTS

A total of 915 patients were included with a mean follow-up time of 30.8 months (standard deviation 17.9). Complications occurred in 542 patients (59.2%) of which 50.2% had a CD grade ≥III complication [ie, (re)intervention, organ dysfunction, or death]. The incidence of anastomotic leakage (AL) was 135 of 915 patients (14.8%) of which 84 patients were classified as a CD grade ≥III. Multivariable analysis showed a significantly deteriorated long-term survival in all patients with AL [hazard ratio (HR) 1.68, 95% confidence interval (CI) 1.25-2.24]. This inverse relation was most distinct when AL was scored as a CD grade ≥III (HR 1.83, 95% CI 1.30-2.58). For all other complications, no significant association with long-term survival was found.

CONCLUSION

The occurrence and severity of AL, but not overall complications, after MIE negatively affect long-term survival of esophageal cancer patients.

Overexpression of U three protein 14a (UTP14a) is associated with poor prognosis of esophageal squamous cell carcinoma

Background

Esophageal squamous cell carcinoma (ESCC) is one of the most aggressive and lethal cancers lacking valid prognostic biomarkers. As an essential component of a large ribonucleoprotein complex, U Three Protein 14a (UTP14a) might play important roles in human tumorigenesis. However, the clinical significance and functions of UTP14a in ESCC still remain unclear.

Methods

From September 2009 to August 2015, 210 patients with ESCC of the thoracic esophagus underwent thoracoscopic esophagectomy in our institute. The corresponding 210 tissue samples and 30 cancer‐distant mucosa (CDM) samples were tested for UTP14a expression by immunohistochemical staining. The long‐term survival was analyzed by the Kaplan–Meier method and Cox proportional hazards regression analyses. CCK8, cell colony formation, cell cycle, apoptosis, cell invasion, and wound healing assays were carried out with ECA109 cells to evaluate the effects of UTP14a on ESCC in vitro.

Results

UTP14a was positively expressed in 88.1% (185/210) of the ESCC samples. UTP14a expression in ESCC was significantly higher than in CDM, as further confirmed by Western blot analysis. High expression of UTP14a in ESCC correlated significantly with tumor invasive depth (pT stage), which predicts poor disease‐free survival and disease‐specific survival, as indicated by the log‐rank test and Cox proportional hazards regression analysis. Additionally, our in vitro experiments further demonstrated that knockdown of UTP14a inhibits cell proliferation and invasion in ECA109 cells.

Conclusions

Our results suggest that UTP14a is aberrantly expressed in ESCC, plays a critical role in cancer progression and could be a potential prognosis predictor of ESCC.

Predictive factors of difficulty of thoracoscopic esophagectomy in the left decubitus position

BACKGROUND

We have sometimes experienced technical difficulty performing thoracoscopic esophagectomy because of the position of the descending aorta or width of the mediastinal space. In this study, we retrospectively investigated predictive preoperative factors that influence the procedure of thoracoscopic esophagectomy with a focus on the position of the descending aorta and width of the mediastinal space.

METHODS

Ninety-five patients who underwent thoracoscopic esophagectomy for esophageal cancer by two specialists were included in this study. Thirty patients in whom both the operation time and blood loss in the thoracic region exceeded the median were categorized to the difficult group. The remaining 65 patients were categorized into the common group. During the evaluation of the position of the descending aorta, we measured the aorta-vertebra angle at the level of the left inferior pulmonary vein. During the evaluation of the width of the mediastinal space, we measured the sternum-vertebra distance at the level of the tracheal bifurcation.

RESULTS

A forward stepwise logistic regression analysis revealed the following independent predictive factors of the technical difficulty of thoracoscopic esophagectomy: aorta-vertebra angle (≥ 30°), sternum-vertebra distance (< 100 mm), and clinical T stage (T3).

CONCLUSIONS

The position of the descending aorta, width of the mediastinal space, and clinical T stage are predictive factors of the technical difficulty of thoracoscopic esophagectomy. These factors might become supporting indices for the indication for thoracoscopic esophagectomy among trainees or the surgeons who introduce this procedure.

Effects of improving outcomes after esophagectomy on the short- and long-term: a review of literature

An esophagectomy is still correlated with a high morbidity rate, despite advances made in minimally invasive surgery, enhanced recovery after surgery (ERAS) and centralization of this type of surgery. The short-term benefits are clearly described for esophageal cancer surgery patients, however, the long-term effects are yet to be determined. In colorectal cancer, the association between complications, especially anastomotic leakage, shows detrimental effects on long-term survival and cancer recurrence. In esophageal cancer surgery, current evidence is scarce and the described results are conflicting. Optimization of perioperative care by introduction of minimally invasive surgery, ERAS programs and patient prehabilitation is promising and shows a clear effect on short-term outcomes. Potentially, this may also result in better outcomes on the long-term, although current evidence is insufficient to infer definite conclusions. Reduction of anastomotic leakage seems important to reduce risk of cancer recurrence and improve long-term outcome.

Technique of robotic assisted minimally invasive esophagectomy (RAMIE)

Minimally invasive esophagectomy (MIE) has gained popularity over the last two decades as an oncologically sound alternative to open esophagectomy. Robotic assisted minimally invasive esophagectomy (RAMIE) has been developed at few highly-specialized centers, and overall experience with this technique remains limited. Herein, we describe our overall approach to this operation and specific technical issues.
