Hybrid and total minimally invasive esophagectomy: how I do it

Does Indocyanine Green Utilization during Esophagectomy Prevent Anastomotic Leaks? Systematic Review and Meta-Analysis

Background: Indocyanine Green (ICG) is a promising technique for the assessment of gastric conduit and anastomosis perfusion during esophagectomy. ICG integration may be helpful in minimizing the risk of anastomotic leak (AL). Literature evidence is sparse, while the real effect of ICG assessment on AL minimization remains unsolved. The aim of this systematic review and meta-analysis was to compare short-term outcomes between ICG-guided and non-ICG-guided (nICG) esophagogastric anastomosis during esophagectomy for cancer. Materials and Methods: PubMed, MEDLINE, Scopus, Web of Science, Cochrane Central Library, and ClinicalTrials.gov were queried up to 25 April 2024. Studies that reported short-term outcomes for ICG versus non-ICG-guided (nICG) anastomosis in patients undergoing esophagectomy were considered. Primary outcome was AL. Risk ratio (RR) and standardized mean difference (SMD) were utilized as effect size measures, whereas to assess relative inference we used 95% confidence intervals (95% CI). Results: Overall, 1399 patients (11 observational studies) were included. Overall, 576 (41.2%) underwent ICG gastric conduit assessment. The patients' ages ranged from 22 to 91 years, with 73% being male. The cumulative incidence of AL was 10.4% for ICG and 15.4% for nICG. Compared to nICG, ICG utilization was related to a reduced risk for postoperative AL (RR 0.48; 95% CI 0.23-0.99; p = 0.05). No differences were found in terms of pulmonary complications (RR 0.83), operative time (SMD -0.47), hospital length of stay (SMD -0.16), or 90-day mortality (RR 1.70). Conclusions: Our study seems to indicate a potential impact of ICG in reducing post-esophagectomy AL. However, because of limitations in the design of the included studies, allocation/reporting bias, variable definitions of AL, and heterogeneity in ICG use, caution is required to avoid potential overestimation of the ICG effect.

Safe Transition from Open to Total Minimally Invasive Esophagectomy for Cancer Utilizing Process Management Methodology

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.

Association of hospital volume and operative approach with clinical and financial outcomes of elective esophagectomy in the United States

INTRODUCTION

Literature regarding the impact of esophagectomy approach on hospitalizations costs and short-term outcomes is limited. Moreover, few have examined how institutional MIS experience affects costs. We thus examined utilization trends, costs, and short-term outcomes of open and minimally invasive (MIS) esophagectomy as well as assessing the relationship between institutional MIS volume and hospitalization costs.

METHODS

All adults undergoing elective esophagectomy were identified from the 2016-2020 Nationwide Readmissions Database. Multiple regression models were used to assess approach with costs, in-hospital mortality, and major complications. Additionally, annual hospital MIS esophagectomy volume was modeled as a restricted cubic spline against costs. Institutions performing > 16 cases/year corresponding with the inflection point were categorized as high-volume hospitals (HVH). We subsequently examined the association of HVH status with costs, in-hospital mortality, and major complications in patients undergoing minimally invasive esophagectomy.

RESULTS

Of an estimated 29,116 patients meeting inclusion, 10,876 (37.4%) underwent MIS esophagectomy. MIS approaches were associated with $10,600 in increased incremental costs (95% CI 8,800-12,500), but lower odds of in-hospital mortality (AOR 0.76; 95% CI 0.61-0.96) or major complications (AOR 0.68; 95% CI 0.60, 0.77). Moreover, HVH status was associated with decreased adjusted costs, as well as lower odds of postoperative complications for patients undergoing MIS operations.

CONCLUSION

In this nationwide study, MIS esophagectomy was associated with increased hospitalization costs, but improved short-term outcomes. In MIS operations, cost differences were mitigated by volume, as HVH status was linked with decreased costs in the setting of decreased odds of complications. Centralization of care to HVH centers should be considered as MIS approaches are increasingly utilized.

Impact of pulmonary complications following esophagectomy on long-term survival: multivariate meta-analysis and restricted mean survival time assessment

Pulmonary complications (PC) are common after esophagectomy and their impact on long-term survival is not defined yet. The present study aimed to assess the effect of postoperative PCs on long-term survival after esophagectomy for cancer. Systematic review of the literature through February 1, 2023, was performed. The included studies evaluated the effect of PC on long-term survival. Primary outcome was long-term overall survival (OS). Cancer-specific survival (CSS) and disease-free survival (DFS) were secondary outcomes. Restricted mean survival time difference (RMSTD), hazard ratio (HR), and 95% confidence intervals (CI) were used as pooled effect size measures. Eleven studies were included (3423 patients). Overall, 674 (19.7%) patients developed PC. The RMSTD analysis shows that at 60-month follow-up, patients not experiencing PC live an average of 8.5 (95% CI 6.2-10.8; p < 0.001) months longer compared with those with PC. Similarly, patients not experiencing postoperative PC seem to have significantly longer CSS (8 months; 95% CI 3.7-12.3; p < 0.001) and DFS (5.4 months; 95% CI 1.6-9.1; p = 0.005). The time-dependent HRs analysis shows a reduced mortality hazard in patients without PC at 12 (HR 0.6, 95% CI 0.51-0.69), 24 (HR 0.64, 95% CI 0.55-0.73), 36 (HR 0.67, 95% CI 0.55-0.79), and 60 months (HR 0.69, 95% CI 0.51-0.89). This study suggests a moderate clinical impact of PC on long-term OS, CSS, and DFS after esophagectomy. Patients not experiencing PC seem to have a significantly reduced mortality hazard up to 5 years of follow-up.

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.

Linear- versus circular-stapled esophagogastric anastomosis during esophagectomy: systematic review and meta-analysis

BACKGROUND

Different techniques have been described for esophagogastric anastomosis. Over the past decades, surgeons have been improving anastomotic techniques with a gradual shift from hand-sewn to stapled anastomosis. Nowadays, circular-stapled (CS) and linear-stapled (LS) anastomosis are commonly used during esophagectomy.

METHODS

PubMed, MEDLINE, Scopus, and Web of Science were searched up to June 2022. The included studies evaluated short-term outcomes for LS vs. CS anastomosis in patients undergoing esophagectomy for cancer. Primary outcomes were anastomotic leak (AL) and stricture (AS). Risk ratio (RR) and standardized mean difference (SMD) were used as pooled effect size measures whereas 95% confidence intervals (95%CI) were used to assess relative inference.

RESULTS

Eighteen studies (2861 patients) were included. Overall, 1371 (47.9%) underwent CS while 1490 (52.1%) LS. Compared to CS, LS was associated with a significantly reduced RR for AL (RR = 0.70; 95% CI 0.54-0.91; p < 0.01) and AS (RR = 0.32; 95% CI 0.20-0.51; p < 0.0001). Stratified subgroup analysis according to the level of anastomosis (cervical and thoracic) still shows a tendency toward reduced risk for LS. No differences were found for pneumonia (RR 0.78; p = 0.12), reflux esophagitis (RR 0.74; p = 0.36), operative time (SMD -0.25; p = 0.16), hospital length of stay (SMD 0.13; p = 0.51), and 30-day mortality (RR 1.26; p = 0.42).

CONCLUSIONS

LS anastomosis seems associated with a tendency toward a reduced risk for AL and AS. Although surgeon's own training and experience might direct the choice of esophagogastric anastomosis, our meta-analysis encourages the use of LS anastomosis.

Meta-analysis of robot-assisted versus video-assisted McKeown esophagectomy for esophageal cancer

We aim to review the available literature on patients with esophageal cancer treated with robot-assisted (RAME) or video-assisted McKeown's esophagectomy (VAME), to compare the efficacy and safety of the two approaches. Original research studies that evaluated perioperative and oncologic outcomes of RAME versus VAME were identified, from January 1990 to July 2022. The 90-day mortality, the R0 resection rate, the dissected lymph nodes, the perioperative parameters, and the complications were calculated according to a fixed and a random effect model. The Q statistics and I² statistic were used to test for heterogeneity among the studies. Seven studies were included, incorporating a total of 1617 patients treated with RAME or VAME. The 90-day mortality was similar between the two groups. No difference was found regarding the R0 resection rate and the number of dissected lymph nodes. In addition, the perioperative parameters, along with the total complications were similar between RAME and VAME. Nonetheless, the incidence of postoperative pneumonia was higher in the VAME group (OR:0.67 [95% CI: 0.49, 0.93]; p = 0.02). Finally, our outcomes were further validated by sensitivity analysis including only studies performing propensity score-matched analysis. Our meta-analysis showed that RAME was equivalent to VAME in terms of safety, feasibility, and oncologic adequacy. These results should be interpreted with caution due to the small number of included studies. New Randomized Controlled trials, that are currently active, will provide further evidence with greater clarity to assess the effectiveness and safety of RAME for esophageal cancer.

End-to-side circular stapled versus side-to-side linear stapled intrathoracic esophagogastric anastomosis following minimally invasive Ivor-Lewis esophagectomy: comparison of short-term outcomes

PURPOSE

The search for the optimal procedure for creation of a safe gastroesophageal intrathoracic anastomosis with a lower risk of leakage in totally minimally invasive Ivor-Lewis esophagectomy (TMIIL) is ongoing. In the present study, we compared the outcomes of end-to-side (with circular stapler [CS]) and side-to-side (with linear stapler [LS]) techniques for intrathoracic anastomosis during TMIIL performed in 2 European high-volume centers for upper gastrointestinal surgery. A propensity score method was used to compare the CS and LS groups.

METHODS

We retrospectively evaluated patients with lower esophageal cancer or Siewert type 1 or 2 esophagogastric junction carcinoma who underwent a planned TMIIL esophagectomy, performed from January 2017 to September 2020. The anastomosis was created by a semi-mechanical technique using a LS in one center and by a mechanical technique using a CS in the other center. General features, operative techniques, pathology data, and short-term outcomes were analyzed. Statistical evaluations were performed on the whole cohort, stratifying the analyses by risk strata factors identified with the propensity scores, and on a subgroup of patients matched by propensity score. The primary endpoint of the study was the rate of anastomotic leakage in the two groups. Secondary endpoints included rates of anastomotic stricture and overall postoperative complications.

RESULTS

Considering the whole population, 256 patients were included; of those, 220 received the anastomosis with a circular stapler (CS group), and 36 received the anastomosis with a linear stapler (LS group). No significant differences by group in terms of sex, age, American Society of Anesthesiologists physical status classification, and type of neoplasm were showed. The rate of anastomotic leakage did not differ in the two groups (9.6% CS vs. 5.6% LS, p = 0.438), as well as the rate of anastomotic stricture in the 3-month follow-up (0.9% CS vs. 2.8% LS, p = 0.367). The rate of chyle leakage and of pulmonary, cardiac, and infective complications was not significantly different in the groups. After propensity score matching, 72 patients were included in the analysis. The 2 obtained propensity score matched groups did not differ for any of the clinical and pathologic variables considered for the analysis, resulting in well-balanced cohorts. The results obtained on the whole population were confirmed in the matched groups.

CONCLUSIONS

The results of our study suggest that both techniques for esophagogastric anastomosis during TMIIL are feasible, safe, and effective, with comparable rates of postoperative anastomotic leakage and stricture.

Comparison of pleural drain amylase and serum C-reactive protein for early detection of intrathoracic esophago-gastric anastomotic leaks

INTRODUCTION

Early detection of anastomotic leaks following esophagectomy has the potential to reduce hospital length of stay and mortality. The aim of this study was to compare the predictive value of pleural drain amylase and serum C-reactive protein for the early diagnosis of leak.

METHODS

A retrospective observational cohort study was conducted on 121 patients who underwent Ivor Lewis esophagectomy and intrathoracic gastric conduit reconstruction. Pleural drain amylase levels were measured daily until postoperative day (POD) 5 and compared with CRP values measured on POD 3, 5, and 7. Specificity and sensitivity for both tests, and the respective ROC curves, were calculated.

RESULTS

Anastomotic leak occurred in 12 patients. There was a significant statistical association between pleural drain amylase and serum CRP levels and the presence of anastomotic leakage. Pleural drain amylase cutoff of 209 IU/L on POD 2 yielded a sensitivity of 75% and a specificity of 94% (AUC = 0.813), whereas CRP cutoff value of 22.5 mg/dL on POD 3 yielded a sensitivity of 56% and a specificity of 92% (AUC = 0.772). The negative likelihood ratio of pleural drain amylase was 0.27 and 0.12 on POD 2 and 5, respectively. There was no statistically significant difference between ROC curves of amylase and CRP on POD 3 and 5 (p = 0.79 and p = 0.14, respectively).

CONCLUSIONS

Pleural drain amylase seems more efficient than serum CRP for early detection of esophago-gastric anastomotic leak. The practice of monitoring drain amylase and CRP may allow safer implementation of enhanced postoperative recovery pathway.

Minimally invasive esophagectomy for cancer in COVID hospitals and oncological hubs: are the outcomes different?

Introduction

The outbreak of coronavirus disease 2019 (COVID-19) has caused significant delays in oncological care worldwide due to restriction of elective surgery and intensive care unit capacity. It has been hypothesized that COVID-free oncological hubs can provide safer elective cancer surgery compared to COVID hospitals. The primary aim of the present study was to analyze the outcomes of minimally invasive esophagectomy for cancer performed in both hospital settings by the same surgical staff.

Methods

All esophagectomies for cancer performed during the pandemic by a single team were reviewed and data were compared with control patients operated during the preceding year. Screening for severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) was performed prior to surgery, and special precautions were taken to mitigate hospital-related transmission of COVID-19 among patients and healthcare workers.

Results

Compared to the prepandemic period, the esophagectomy volume decreased by 64%. Comorbidities, time from onset of symptoms to first visit, waiting time between diagnosis and surgery, operative approach and technique, and the pathological staging were similar. None of the patients tested positive for COVID-19 during in-hospital stay, and esophagectomy was associated with similar outcomes compared to control patients.

Conclusion

Outcomes of minimally invasive esophagectomy for cancer performed in a COVID hospital after implementation of a COVID-free surgical pathway did not differ from those obtained in an oncological hub by the same surgical team.

Peri-operative approach to esophagectomy: a narrative review from the anesthesiological standpoint

Objective

This review summarizes the peri-operative anesthesiological approaches to esophagectomy considering the best up-to-date, evidence-based medicine, discussed from the anesthesiologist’s standpoint.

Background

Esophagectomy is the only curative therapy for esophageal cancer. Despite the many advancements made in the surgical treatment of this tumour, esophagectomy still carries a morbidity rate reaching 60%. Patients undergoing esophagectomy should be referred to high volume centres where they can receive a multidisciplinary approach to treatment, associated with better outcomes. The anesthesiologist is the key figure who should guide the peri-operative phase, from diagnosis through to post-surgery rehabilitation. We performed an updated narrative review devoted to the study of anesthesia management for esophagectomy in cancer patients.

Methods

We searched MEDLINE, Scopus and Google Scholar databases from inception to May 2021. We used the following terms: “esophagectomy”, “esophagectomy AND pre-operative evaluation”, “esophagectomy AND protective lung ventilation”, “esophagectomy AND hemodynamic monitoring” and “esophagectomy AND analgesia”. We considered only articles with abstract written in English and available to the reader. We excluded single case-reports.

Conclusions

Pre-operative anesthesiological evaluation is mandatory in order to stratify and optimize any medical condition. During surgery, protective ventilation and judicious fluid management are the cornerstones of intraoperative “protective anesthesia”. Post-operative care should be provided by an intensive care unit or high-dependency unit depending on the patient’s condition, the type of surgery endured and the availability of local resources. The provision of adequate post-operative analgesia favours early mobilization and rapid recovery. Anesthesiologist has an important role during the peri-operative care for esophagectomy. However, there are still some topics that need to be further studied to improve the outcome of these patients.

Three-field versus two-field lymphadenectomy for esophageal squamous cell carcinoma: A long-term survival meta-analysis

BACKGROUND

In the setting of esophageal squamous cell carcinoma, controversy exists regarding the optimal extent of lymphadenectomy, while conclusive evidence regarding the advantages of 3-field versus 2-field lymphadenectomy remains controversial. The purpose of the present meta-analysis was to investigate the effect of 3-field lymphadenectomy versus 2-field lymphadenectomy on overall survival.

METHODS

Systematic review and meta-analyses were computed to compare 3-field lymphadenectomy versus 2-field lymphadenectomy in the setting of esophageal squamous cell carcinoma. Risk ratio, weighted mean difference, hazard ratio, and restricted mean survival time difference were used as pooled effect size measures.

RESULTS

Fourteen studies (3,431 patients) were included. Overall, 1,664 (48.8%) patients underwent 3-field lymphadenectomy, and 1,767 (51.5%) underwent 2-field lymphadenectomy. Three-field lymphadenectomy was associated with a significantly improved 5-year overall survival (hazard ratio: 0.80; 95% confidence interval 0.71-0.90; P < .001). The restricted mean survival time difference showed a statistically significant difference between 3-field lymphadenectomy versus 2-field lymphadenectomy up to 48 months (1.6 months; P = .04), however, no significant differences were found at 60-month follow-up (1.2 months; P = .14). No significant differences were found in term of postoperative mortality, anastomotic leak, pulmonary complications, chylothorax, and recurrent nerve palsy.

CONCLUSION

For resectable esophageal squamous cell carcinoma, 3-field lymphadenectomy seems associated with a slight trend toward improved 5-year overall survival; however, its clinical benefit remains limited.

Diaphragmatic herniation after esophagogastric surgery: systematic review and meta-analysis

Introduction

The anatomy of the esophageal hiatus is altered during esophagogastric surgery with an increased risk of postoperative hiatus hernia (HH). The purpose of this article was to examine the current evidence on the surgical management and outcomes associated with HH after esophagogastric surgery for cancer.

Materials and methods

Systematic review and meta-analysis. Web of Science, PubMed, and EMBASE data sets were consulted.

Results

Twenty-seven studies were included for a total of 404 patients requiring surgical treatment for HH after esophagogastric surgery. The age of the patients ranged from 35 to 85 years, and the majority were males (82.3%). Abdominal pain, nausea/vomiting, and dyspnea were the commonly reported symptoms. An emergency repair was required in 51.5%, while a minimally invasive repair was performed in 48.5%. Simple suture cruroplasty and mesh reinforced repair were performed in 65% and 35% of patients, respectively. The duration between the index procedure and HH repair ranged from 3 to 144 months, with the majority (67%) occurring within 24 months. The estimated pooled prevalence rates of pulmonary complications, anastomotic leak, overall morbidity, and mortality were 14.1% (95% CI = 8.0–22.0%), 1.4% (95% CI = 0.8–2.2%), 35% (95% CI = 20.0–54.0%), and 5.0% (95% CI = 3.0–8.0%), respectively. The postoperative follow-up ranged from 1 to 110 months (mean = 24) and the pooled prevalence of HH recurrence was 16% (95% CI = 13.0–21.6%).

Conclusions

Current evidence reporting data for HH after esophagogastric surgery is narrow. The overall postoperative pulmonary complications, overall morbidity, and mortality are 14%, 35%, and 5%, respectively. Additional studies are required to define indications and treatment algorithm and evaluate the best technique for crural repair at the index operation in an attempt to minimize the risk of HH.

Progress in the esophagogastric anastomosis and the challenges of minimally invasive thoracoscopic surgery

The esophagogastric anastomosis is most commonly performed to restore digestive tract continuity after esophagectomy for cancer. Despite a long history of clinical research and development of high-tech staplers, this procedure is still feared by most surgeons and associated with a 10% leakage rate. Among specific factors that may contribute to failure of the esophageal anastomosis are the absence of serosa layer, longitudinal orientation of muscle fibers, and ischemia of the gastric conduit. It has recently been suggested that the gut microbiome may influence the healing process of the anastomosis through the presence of collagenolytic bacterial strains, indicating that suture breakdown is not only a matter of collagen biosynthesis. The esophagogastric anastomosis can be performed either in the chest or neck, and can be completely hand-sewn, completely stapled (circular or linear stapler), or semi-mechanical (linear stapler posterior wall and hand-sewn anterior wall). Because of the lack of randomized clinical trials, no conclusive evidence is available, and the debate between the hand-sewn and the stapling technique is still ongoing even in the present era of robotic surgery. Centralization of care has improved the overall postoperative outcomes of esophagectomy, but the esophagogastric anastomosis remains the Achille’s heel of the procedure. More research and network collaboration of experts is needed to improve safety and clinical outcomes.

Surgical treatment of recalcitrant gastroesophageal reflux disease in patients with systemic sclerosis: a systematic review

Introduction

Gastroesophageal reflux disease (GERD) is frequently seen in patients with systemic sclerosis (SSc). Long-standing GERD may cause esophagitis, long-segment strictures, and Barrett’s esophagus and may worsen pre-existing pulmonary fibrosis with an increased risk of end-stage lung disease. Surgical treatment of recalcitrant GERD remains controversial. The purpose of this systematic review was to summarize the current data on surgical treatment of recalcitrant GERD in SSc patients.

Materials and methods

A systematic literature review according to PRISMA and MOOSE guidelines. PubMed, EMBASE, and Web of Science databases were consulted.

Results

A total of 101 patients were included from 7 studies. The age ranged from 34 to 61 years and the majority were females (73.5%). Commonly reported symptoms were heartburn (92%), regurgitation (77%), and dysphagia (74%). Concurrent pulmonary disease was diagnosed in 58% of patients. Overall, 63 patients (62.4%) underwent open fundoplication, 17 (16.8%) laparoscopic fundoplication, 15 (14.9%) Roux en-Y gastric bypass (RYGB), and 6 (5.9%) esophagectomy. The postoperative follow-up ranged from 12 to 65 months. Recurrent symptoms were described in up to 70% and 30% of patients undergoing fundoplication and RYGB, respectively. Various symptoms were reported postoperatively depending on the type of surgical procedures, anatomy of the valve, need for esophageal lengthening, and follow-up.

Conclusions

The treatment of recalcitrant GERD in SSc patients is challenging. Esophagectomy should be reserved to selected patients. Minimally invasive RYGB appears feasible and safe with promising preliminary short-term results. Current evidence is scarce while a definitive indication about the most appropriate surgical treatment is lacking.

Hybrid esophagectomy for oesophageal cancer: long-term results. A single-centre experience

Introduction

The authors report long-term outcomes in patients who received neoadjuvant chemoradiotherapy and consequently underwent hybrid oesophagectomy for oesophageal cancer (OC).

Aim

To evaluate long-term outcomes in patients suffering from OC, who underwent hybrid oesophagectomy.

Material and methods

Our cohort consisted of patients suffering from OC, who received neoadjuvant chemoradiotherapy. Hybrid esophagectomy was performed 8–10 weeks after oncological treatment.

Results

Ninety-four patients underwent surgery for OC from 2011 to 2015. Histology revealed adenocarcinoma in 60.6%, squamous cell carcinoma (SCC) in 36.2%, and other type of cancer in 3.2%. Seventy-three (77.7%) patients with advanced stage (T3-4, N0-2, M0) were indicated to receive neoadjuvant chemoradiotherapy (nCRT). Trans-hiatal hybrid oesophagectomy was performed in 83 (88.3%) patients. Transthoracic hybrid oesophagectomy was performed in 11 (11.7%) patients. Histology of the resected specimens of 18 (24.7%) patients did not reveal OC, i.e. pathological complete response (pCR). In our cohort, we proved an association between occurrence of pCR and age as well as disease-free survival (DFS). The patients who presented with pCR were significantly younger – below 60 years of age (p = 0.017). They also showed significantly higher mean DFS (p = 0.004).

Conclusions

Combined oesophagectomy with neoadjuvant chemoradiotherapy results in a better long-term outcome in patients suffering from oesophageal cancer. In our set of patients who underwent hybrid esophagectomy, satisfactory short-term and especially long-term results of surgical treatment for oesophageal cancer were observed.

Minimally invasive surgical management of Boerhaave's syndrome: a narrative literature review

Treatment of Boerhaave's syndrome is controversial. Formal thoracotomy and laparotomy were considered the gold standard treatment in the past. However, these approaches are associated with significant surgical trauma, stress, and postoperative pain. Recently published studies reported the application of minimally invasive surgery in the setting of such esophageal emergency. However, the application of minimally invasive surgery in the setting of Boerhaave's syndrome is debated and evidence is puzzled. The aim of this study was to summarize the current knowledge on minimally invasive treatment of Boerhaave's syndrome. PubMed, EMBASE, and Web of Science databases were consulted. All articles that described the management of Boerhaave's syndrome in the setting of minimally invasive surgery (thoracoscopy or laparoscopy) were included. Sixteen studies and forty-eight patients were included. The age of the patient population ranged from 37 to 81 years old and 74% were males. The time shift period from symptoms onset to surgical treatment ranged from 5 to 240 hours with 10 patients (20.8%) having surgery more than 24 hours from symptoms onset. Vomiting (100%), chest/epigastric pain (88%), and dyspnea (62%) were the most commonly reported symptoms. The perforation size ranged from 6 to 30 mm with 96% of patients suffering from distal esophageal tear. Video-assisted thoracoscopy (VATS) was the most commonly reported surgical approach (75%), followed by laparoscopy (16.7%), and combined thoraco-laparoscopy (6.2%). In case of VATS, a left approach was adopted in 91% of patients with selective lung ventilation. Primary suture was the most commonly performed surgical procedure (60%) with interrupted single or dual-layer repair. Surgical debridement (25%), primary repair reinforced with gastric or omental patch (8%), esophageal repair over T-tube (6%), and endoscopic stenting combined with laparoscopic debridement (2%) were also reported. The postoperative morbidity was 64.5% with pneumonia (42%), pleural empyema (26%), and leak (19%) being the most commonly reported complications. The overall mortality was 8.3%. Boerhaave's syndrome is a rare entity. Minimally invasive surgical treatment seems promising, feasible, and safe in selected patients with early presentation and stable vital signs managed in referral centers. In the management algorithm of Boerhaave's syndrome, a definitive indication to adopt minimally invasive surgery is lacking and its potential role mandates further analysis.

Effectiveness of Transthoracic Hybrid Minimally Invasive Esophagectomy: A Meta-Analysis

BACKGROUND

Transthoracic hybrid minimally invasive esophagectomy (HMIE) is frequently performed in patients with esophageal cancer. However, no conclusive benefit has been defined for HMIE compared with open esophagectomy (OE) or totally MIE (TMIE). The aim of this meta-analysis is to evaluate the effectiveness of HMIE compared with OE and TMIE.

METHODS

PubMed, Embase (via OVID) and Cochrane databases were comprehensively searched for relevant studies up to January 2019. Studies comparing the efficacy of transthoracic HMIE with OE or TMIE were included in this meta-analysis.

RESULTS

Twenty-nine relevant studies comprising 3994 patients were identified and included in the analysis of HMIE vs OE. HMIE decreased the incidence of postoperative total morbidity (OR = 0.66, 95% CI 0.55 to 0.80, p = 0.00), pneumonia (OR = 0.55, 95% CI 0.45 to 0.66, p = 0.00), in-hospital mortality (OR = 0.54, 95% CI 0.36 to 0.83, p = 0.01), duration of hospitalization (SMD=-1.03, 95% CI -1.73 to -0.33, p = 0.00) and the estimated intraoperative blood loss (SMD=-1.01, 95% CI -1.62 to -0.40, p = 0.00) compared with OE. Twenty-one relevant studies comprising 3007 patients were identified and included in the analysis of HMIE vs TMIE. HMIE increased estimated intraoperative blood loss [standardized mean difference (SMD) = 1.02, 95% CI 0.45 to 1.58, p = 0.00] and the incidence of postoperative pneumonia (OR = 1.69, 95% CI 1.26 to 2.26, p = 0.00) compared with TMIE. No statistical differences were observed for other surgical outcomes.

CONCLUSIONS

In our opinion, HMIE is a promising surgical technique. But further RCTs are still needed to confirm the advantages and disadvantages of HMIE mentioned above.

Semi-prone video-assisted thoracoscopy for the treatment of large infracarinal traction diverticula

BACKGROUND

Large middle-third esophageal diverticula are rare. Thoracotomy has been proposed as mainstay of treatment; however, minimally invasive resection through lateral or prone position thoracoscopy has been described.

METHODS

The technical aspects of the novel semi-prone minimally invasive thoracoscopy (spVATS) in the management of large (> 5 cm) infracarinal traction diverticula are described. Operative outcomes, pre- and postoperative symptoms (Eckardt score) and quality of life (Short-Form 36) are analyzed.

RESULTS

Four symptomatic patients underwent spVATS for traction midesophageal diverticula. The median age was 59 years and 75% were males. The median diverticulum size was 7.0 cm (range 5.5-8). The median preoperative Eckardt score was 8.4 (range 5-10), and the overall incidence of respiratory symptoms was 50%. Esophageal manometry was performed in three patients with no evidence of underlying motility disorders. The median operative time was 149 min (range 125-175). No intraoperative complications or open conversions occurred. Postoperative morbidity and mortality were 25% and 0%, respectively. The median hospital length of stay was 7.5 days (range 6-10). The median postoperative follow-up was 22 months (range 5-35). At the last follow-up, there was a significant improvement of patients' symptoms (p = 0.024) and quality of life (p < 0.05) with complete resolution of respiratory symptoms.

CONCLUSION

In summary, spVATS seems a valuable approach to treat large midesophageal traction diverticula in centers experienced with minimally invasive esophageal surgery. Further studies are needed to validate the advantages and promising outcomes of the spVATS providing more robust evidence on the treatment of this rare clinical entity.

Anastomosis after Minimally Invasive Esophagectomy

BACKGROUND

Esophagectomies are a notoriously difficult procedure that have undergone drastic changes over the last decade. In particular, the adoption of minimally invasive esophagectomies (MIEs) as the gold standard.

METHODS

We examine the evolution of the MIE, the support for this method, and our preferred methods for the creation of anastomoses following the resection.

RESULTS

The submission of techniques that, after many years of practice, have become our standard methods for anastomosing the Neo-esophagus to the remnant esophagus both at the neck, and within the thorax.

CONCLUSION

No matter which MIE technique is chosen, these anastomotic methods are readily available. Each is provided with step-by-step instructions, performed with standard laparoscopic instruments, and in a safe and reproducible manner.

Use of C-reactive protein for the early prediction of anastomotic leak after esophagectomy: Systematic review and Bayesian meta-analysis

BACKGROUND

Early suspicion, diagnosis, and timely treatment of anastomotic leak after esophagectomy is essential. Retrospective studies have investigated the role of C-reactive protein (CRP) as early marker of anastomotic leakage. The aim of this systematic review and meta-analysis was to evaluate the predictive value of CRP after esophageal resection.

METHODS

A literature search was conducted to identify all reports including serial postoperative CRP measurements to predict anastomotic leakage after elective open or minimally invasive esophagectomy. Fully Bayesian meta-analysis was carried out using random-effects model for pooling diagnostic accuracy measures along with CRP cut-off values at different postoperative day.

RESULTS

Five studies published between 2012 and 2018 met the inclusion criteria. Overall, 850 patients were included. Ivor-Lewis esophagectomy was the most common surgical procedure (72.3%) and half of the patients had squamous-cell carcinoma (50.4%). The estimated pooled prevalence of anastomotic leak was 11% (95% CI = 8-14%). The serum CRP level on POD3 and POD5 had comparable diagnostic accuracy with a pooled area under the curve of 0.80 (95% CIs 0.77-0.92) and 0.83 (95% CIs 0.61-0.96), respectively. The derived pooled CRP cut-off values were 17.6 mg/dl on POD 3 and 13.2 mg/dl on POD 5; the negative likelihood ratio were 0.35 (95% CIs 0.096-0.62) and 0.195 (95% CIs 0.04-0.52).

CONCLUSION

After esophagectomy, a CRP value lower than 17.6 mg/dl on POD3 and 13.2 mg/dl on POD5 combined with reassuring clinical and radiological signs may be useful to rule-out leakage. In the context of ERAS protocols, this may help to avoid contrast radiological studies, anticipate oral feeding, accelerate hospital discharge, and reduce costs.

Initial experience with uniportal video-assisted thoracic surgery esophagectomy

Background

Multiportal thoracoscopic approach is already a well standardized procedure for minimally invasive esophagectomy (MIE); conversely very few reports have been published about uniportal video-assisted thoracic surgery (VATS) technique till now. We present our preliminary experience with uniportal VATS esophagectomy, evaluating short-term outcomes as perioperative mortality, complications, oncological radicality, postoperative pain and cosmetic results.

Methods

From December 2016 to November 2017, the prospectively collected clinical data of 12 patients, who underwent uniportal VATS esophagectomy and reconstruction with a stomach conduit, according to McKeown technique, were reviewed and outcomes evaluated.

Results

The mean age of population was 60.67±8.61 years. Ten (83.3%) patients were males. The main histological type was a squamous cell carcinoma in six patients (50%). No patient had a local recurrence. After 4.33±3.31 months 10 patients (83.3%) were alive with no evidence of disease; 2 (16.7%) patients died of other causes. Two (16.7%) patients developed an anastomotic leak (treated conservatively) and one (8.3%) patient a chylothorax (which required a surgical treatment). The mean operative time of uniportal VATS esophagectomy was 104.67±20.66 min. Mean number of thoracic nodes removed was 10.44±3.94. Post-operative hospitalization was 15.73±14.29 days (median of 9 days). The mean level of pain was 1.92±0.90 in first postoperative day with a duration of 2.25±1.54 days. Cosmetic result was 2.42±0.79 on a 3-point scale.

Conclusions

Uniportal VATS esophagectomy seems to be a safe, feasible and effective alternative to multiportal VATS in terms of operative time, postoperative mortality, hospital stay and oncological outcomes. Less postoperative pain and better cosmetic results seem to be some advantages in favor of Uniportal VATS, however further studies with longer follow-up are claimed.

Minimally invasive esophagectomy for Barrett's adenocarcinoma

Minimally invasive esophagectomy has become the preferred approach for invasive Barrett's adenocarcinoma because it can speed recovery and enhance patient's quality of life. Multiple minimally invasive surgical techniques have been described during the last two decades. Preoperative staging, anatomy and physiological patient's status, comorbidity, and experience of the surgical team should drive the choice of the surgical approach. The trans-thoracic Ivor Lewis esophagectomy, either hybrid or totally minimal invasive, remains the preferred approach in these patients. Lymph node yield and short-term clinical outcomes have proven similar to open surgery, while quality of life appears improved. To establish a minimally invasive esophagectomy program, a steep learning curve and a multidisciplinary approach are required in order to provide optimal staging, personalized therapy, and adequate perioperative care. The role of minimally invasive surgery in the treatment of invasive Barrett's adenocarcinoma will continue to expand in synergy with enhanced recovery after surgery pathways.

Flexible versus rigid endoscopy in the management of esophageal foreign body impaction: systematic review and meta-analysis

Background

Foreign body (FB) impaction accounts for 4% of emergency endoscopies in clinical practice. Flexible endoscopy (FE) is recommended as the first-line therapeutic option because it can be performed under sedation, is cost-effective, and is well tolerated. Rigid endoscopy (RE) under general anesthesia is less used but may be advantageous in some circumstances. The aim of the study was to compare the efficacy and safety of FE and RE in esophageal FB removal.

Methods

PubMed, MEDLINE, Embase, and Cochrane databases were consulted matching the terms "Rigid endoscopy AND Flexible endoscopy AND foreign bod*". Pooled effect measures were calculated using an inverse-variance weighted or Mantel-Haenszel in random effects meta-analysis. Heterogeneity was evaluated using I2 index and Cochrane Q test.

Results

Five observational cohort studies, published between 1993 and 2015, matched the inclusion criteria. One thousand four hundred and two patients were included; FE was performed in 736 patients and RE in 666. Overall, 101 (7.2%) complications occurred. The most frequent complications were mucosal erosion (26.7%), mucosal edema (18.8%), and iatrogenic esophageal perforations (10.9%). Compared to FE, the estimated RE pooled success OR was 1.00 (95% CI 0.48-2.06; p = 1.00). The pooled OR of iatrogenic perforation, other complications, and overall complications were 2.87 (95% CI 0.96-8.61; p = 0.06), 1.09 (95% CI 0.38-3.18; p = 0.87), and 1.50 (95% CI 0.53-4.25; p = 0.44), respectively. There was no mortality.

Conclusions

FE and RE are equally safe and effective for the removal of esophageal FB. To provide a tailored or crossover approach, patients should be managed in multidisciplinary centers where expertise in RE is also available. Formal training and certification in RE should probably be re-evaluated.

Outcomes of Transhiatal and Intercostal Pleural Drain After Ivor Lewis Esophagectomy: Comparative Analysis of Two Consecutive Patient Cohorts

BACKGROUND

In a previous proof of concept study, transhiatal pleural drain has been shown to be safe and effective after hybrid Ivor Lewis esophagectomy. Aim of this study was to compare the short-term outcomes of transhiatal and intercostal pleural drainage.

PATIENTS AND METHODS

This is an observational retrospective cohort study. Two methods of pleural drainage were compared in patients undergoing hybrid Ivor Lewis esophagectomy. Patients treated with a transhiatal drain connected to a vacuum bag were compared to a historical cohort of patients treated with the conventional intercostal drain connected to underwater seal and suction. Postoperative morbidity, total and daily drainage output, serum albumin levels, and total dose of paracetamol and ketorolac administered on demand were recorded.

RESULTS

Between January 2014 and December 2016, 50 patients with transhiatal drain and 50 with intercostal drains met the criteria for inclusion in the study. Demographic and clinicopathological variables were similar in the two groups. There was no statistically significant difference in the rate of postoperative complications. The total volume of drain output and the serum albumin levels were similar in the two groups. The total dose of ketorolac was significantly reduced in patients with transhiatal drain (P < .001).

CONCLUSIONS

Transhiatal pleural drainage connected to a portable vacuum system could safely replace the intercostal drain after hybrid Ivor Lewis esophagectomy. It has the potential to reduce postoperative pain and use of nonsteroidal anti-inflammatory drugs, and to enhance recovery from surgery.

Esophageal Resection for End-Stage Achalasia

Achalasia is a rare disease characterized by impaired lower esophageal sphincter relaxation loss and of peristalsis in the esophageal body. Endoscopic balloon dilation and laparoscopic surgical myotomy have been established as initial treatment modalities. Indications and outcomes of esophagectomy in the management of end-stage achalasia are less defined. A literature search was conducted to identify all reports on esophagectomy for end-stage achalasia between 1987 and 2017. MEDLINE, Embase, and Cochrane databases were consulted matching the terms “achalasia,” “end-stage achalasia,” “esophagectomy,” and “esophageal resection.” Seventeen articles met the inclusion criteria and 1422 patients were included in this narrative review. Most of the patients had previous multiple endoscopic and/or surgical treatments. Esophagectomy was performed through a transthoracic (74%) or a transhiatal (26%) approach. A thoracoscopic approach was used in a minority of patients and seemed to be safe and effective. In 95 per cent of patients, the stomach was used as an esophageal substitute. The mean postoperative morbidity rate was 27.1 per cent and the mortality rate 2.1 per cent. Symptom resolution was reported in 75 to 100 per cent of patients over a mean follow-up of 43 months. Only five series including 195 patients assessed the long-term follow-up (>5 years) after reconstruction with gastric or colon conduits, and the results seem similar. Esophagectomy for end-stage achalasia is safe and effective in tertiary referral centers. A thoracoscopic approach is a feasible and safe alternative to thoracotomy and may replace the transhiatal route in the future.

Utility of C-reactive protein as predictive biomarker of anastomotic leak after minimally invasive esophagectomy

BACKGROUND

Early detection of anastomotic leakage after esophagectomy has the potential to reduce morbidity and mortality. Prompt suspicion of leak may help to exclude patients from fast-track protocols, thereby avoiding early oral feeding and early hospital discharge which could aggravate the prognosis of a clinically occult leak.

PATIENTS AND METHODS

Observational retrospective cohort study. Patients with diagnosis of esophageal cancer who underwent elective minimally invasive esophagectomy were included. The following data were collected: age, gender, BMI, comorbidities, ASA score, tumor histology, TNM staging, use of neo-adjuvant therapy, type of operation, operative time, morbidity, and 90-day mortality. A panel of biomarkers including C-reactive protein (CRP), procalcitonin (PCT), white blood cells (WBC), and percentage of neutrophils (PN) were measured at baseline and on postoperative days 3, 5, and 7.

RESULTS

Two hundred forty-three patients operated between 2012 and 2017 were included in the study. Anastomotic leakage occurred in 29 patients. There was a statistical association over time between anastomotic leakage and CRP (p < 0.001), PCT (p < 0.001), WBC (p = 0.019), and PN (p = 0.007). The cut-off value of CRP on POD 5 was 8.3 mg/dL, AUC = 0.818, negative LR = 0.176.

CONCLUSIONS

Increased serum CRP, PCT, WBC, and PN after minimally invasive esophagectomy are associated with anastomotic leakage. A CRP value lower than 8.3 mg/dL, combined with reassuring clinical and radiological signs, may be useful to exclude leakage on postoperative day 5.
