Management and outcomes of anastomotic leaks after oesophagectomy

Navigating complexities and considerations for suspected anastomotic leakage in the upper gastrointestinal tract: A state of the art review

This state-of-the-art review explores the intricacies of anastomotic leaks following oesophagectomy and gastrectomy, crucial surgeries for globally increasing esophageal and gastric cancers. Despite advancements, anastomotic leaks occur in up to 30 % and 10 % of oesophagectomy and gastrectomy cases, respectively, leading to prolonged hospital stays, substantial impact upon short- and long-term health-related quality of life and greater mortality. Recognising factors contributing to leaks, including patient characteristics and surgical techniques, are vital for preoperative risk stratification. Diagnosis is challenging, involving clinical signs, biochemical markers, and various imaging modalities. Management strategies range from non-invasive approaches, including antibiotic therapy and nutritional support, to endoscopic interventions such as stent placement and emerging vacuum-assisted closure devices, and surgical interventions, necessitating timely recognition and tailored interventions. A step-up approach, beginning non-invasively and progressing based on treatment success, is more commonly advocated. This comprehensive review highlights the absence of standardised treatment algorithms, emphasizing the importance of individualised patient-specific management.

Pre-operative psoas muscle index, a surrogate for sarcopenia; as a predictor of post-esophagectomy complications

BACKGROUND

Esophagectomy is the standard of care for curative esophageal cancer. However, it is associated with significant morbidity and mortality. Esophageal cancer is known to negatively affect the nutritional status of patients and many manifest cancer sarcopenia. At present, measures of sarcopenia involve complex and often subjective measurements. We assess whether the Psoas Muscle Index (PMI); an inexpensive, simple, validated method used to diagnose sarcopenia, can be used to predict adverse outcomes in patients after curative esophagectomy.

METHODS

Multi-centre, retrospective cohort between 2010-2020, involving all consecutive patients undergoing curative esophagectomy for esophageal cancer in University Malaya Medical Centre, Sungai Buloh Hospital, and Sultanah Aminah Hospital. The cut-off value differentiating low and normal PMI is defined as 443mm2/m2 in males and 326326 mm2/m2 in females. Complications were recorded using the Clavien-Dindo Scale.

RESULTS

There was no statistical correlation between PMI and major post-esophagectomy complications (p-value: 0.495). However, complication profile was different, and patients with low PMIs had higher 30-day mortality (21.7%) when compared with patients with normal PMI (8.1%) (p-value: 0.048).

CONCLUSIONS

Although PMI did not significantly predict post-esophagectomy complications, low PMI correlates with higher 30-day mortality, reflecting a lower tolerance for complications among these patients. PMI is a useful, inexpensive tool to identify sarcopenia and aids the patient selection process. This alerts healthcare professionals to institute intensive physiotherapy and nutritional optimization prior to esophagectomy.

Long-term survival is not affected by severity of complications following esophagectomy

INTRODUCTION

Outcomes following esophagectomy for esophageal cancer have continued to improve over the last 30 years. Post-operative complications impact upon peri-operative and short-term survival but the effect on long-term survival remains debated. This study aims to investigate the effect of post-operative complications on long-term survival following esophagectomy.

MATERIALS AND METHODS

All patients who underwent an esophagectomy between January 2010 and January 2019 were included from a single high-volume center. Data was collected contemporaneously. Patients were separated into three groups; those who experienced no, or very minor complications (Clavien-Dindo 0 or 1), minor complications (Clavien-Dindo 2), and major complications (Clavien-Dindo 3-4), at 30 days. To correct for short-term mortality effects, those who died during the index hospital admission were excluded. Overall survival was analyzed using Kaplan-Meier and log rank testing.

RESULTS

The study cohort comprised 721 patients. There were 42.4% (306/721), 29.5% (213/721) and 25.7% (185/721) in the Clavien-Dindo 0-1, Clavien-Dindo 2, and Clavien-Dindo 3-4 group respectively. Seventeen patients (2.4%) died during their index hospital admission and were therefore excluded. There was no significant difference between median survival across the 3 groups (50, 57 and 52 months). Across all 3 groups, overall long-term survival rates were equivalent at 1 (87.5%, 84.9%, 83.2%), 3 (59.7%, 59.6%, 54.2%), and 5 years (43.9%, 48.9%, 45.7%) (p = 0.806). The only factors independently associated with survival in this cohort, were male gender, Charlson comorbidity index, and overall pathological stage of disease.

CONCLUSION

Long-term survival is not affected by peri-operative complications, irrespective of severity, following esophagectomy. Further study into the long-term quality of life is required.

The relationship between preoperative anemia and length of hospital stay among patients undergoing radical surgery for esophageal carcinoma: a single-centre retrospective study

BACKGROUND

Although it is unclear if preoperative anemia affects patients undergoing radical resection of esophageal cancer, it does increase the length of stay (LOS) for surgical patients. Accordingly, the purpose of this study was to investigate if, after adjusting for other covariates, anemia was independently associated with LOS in people undergoing radical resection of esophageal cancer.

METHODS

The retrospective cohort study included 680 patients undergoing radical esophageal cancer surgery between January 2010 and December 2020. Preoperative anemia was the targeted independent variable, while LOS was the target independent variable. Demographics, comorbidities, laboratory tests, surgery and anesthesia, postoperative outcomes, and complications were collected. Multivariate linear analyses were performed for variables that might influence preoperative anemia and LOS selection. Subgroup analysis using hierarchical variables was then used to test the potential relationship.

RESULTS

The 647 individuals that were randomly chosen had an average age of 61.06 ± 8.16 years, and 77.43% of them were male. The prevalence of anemia was 36.6%. All patients recruited had an average length of stay (LOS) of 26.31 ± 13.19 days, 25.40 ± 11.44 days for patients who had no preoperative anemia, and 27.89 ± 15.66 days for patients who had preoperative anemia, p < 0.05. After adjusting for covariates, the results of fully adjusted linear regression revealed that preoperative anemia was significantly associated with LOS (β = 2.04, 95%CI (0.13, 3.96) ), p < 0.05. The results of the subgroup analysis were basically accurate and steady. Regardless of gender, same outcomes were seen when preoperative anemia was defined as a Hb level < 13 g/dL (β = 2.29, 95%CI (0.33, 4.25) ), p < 0.05. In addition, the LOS was shortened with the increase of preoperative hemoglobin (Hb) (β= -0.81, 95%CI (-1.46, -0.1) ), p < 0.05.

CONCLUSION

Preoperative anemia is typical in Chinese patients undergoing radical esophageal cancer resection and is independently associated with prolonged LOS.

Treatment of anastomotic leak after oesophagectomy for oesophageal cancer: large, collaborative, observational TENTACLE cohort study

BACKGROUND

Anastomotic leak is a severe complication after oesophagectomy. Anastomotic leak has diverse clinical manifestations and the optimal treatment strategy is unknown. The aim of this study was to assess the efficacy of treatment strategies for different manifestations of anastomotic leak after oesophagectomy.

METHODS

A retrospective cohort study was performed in 71 centres worldwide and included patients with anastomotic leak after oesophagectomy (2011-2019). Different primary treatment strategies were compared for three different anastomotic leak manifestations: interventional versus supportive-only treatment for local manifestations (that is no intrathoracic collections; well perfused conduit); drainage and defect closure versus drainage only for intrathoracic manifestations; and oesophageal diversion versus continuity-preserving treatment for conduit ischaemia/necrosis. The primary outcome was 90-day mortality. Propensity score matching was performed to adjust for confounders.

RESULTS

Of 1508 patients with anastomotic leak, 28.2 per cent (425 patients) had local manifestations, 36.3 per cent (548 patients) had intrathoracic manifestations, 9.6 per cent (145 patients) had conduit ischaemia/necrosis, 17.5 per cent (264 patients) were allocated after multiple imputation, and 8.4 per cent (126 patients) were excluded. After propensity score matching, no statistically significant differences in 90-day mortality were found regarding interventional versus supportive-only treatment for local manifestations (risk difference 3.2 per cent, 95 per cent c.i. -1.8 to 8.2 per cent), drainage and defect closure versus drainage only for intrathoracic manifestations (risk difference 5.8 per cent, 95 per cent c.i. -1.2 to 12.8 per cent), and oesophageal diversion versus continuity-preserving treatment for conduit ischaemia/necrosis (risk difference 0.1 per cent, 95 per cent c.i. -21.4 to 1.6 per cent). In general, less morbidity was found after less extensive primary treatment strategies.

CONCLUSION

Less extensive primary treatment of anastomotic leak was associated with less morbidity. A less extensive primary treatment approach may potentially be considered for anastomotic leak. Future studies are needed to confirm current findings and guide optimal treatment of anastomotic leak after oesophagectomy.

Routine decompression by nasogastric tube after oesophagectomy for oesophageal cancer

This is a protocol for a Cochrane Review (intervention). The objectives are as follows:

To evaluate the effects of routine nasogastric decompression as compared to no nasogastric decompression after oesophagectomy. In the case of routine decompression, we will also aim to assess the effects of early versus late removal of the nasogastric tube.

Management of anastomotic leakage after robot-assisted minimally invasive esophagectomy with an intrathoracic anastomosis

Anastomotic leakage is a feared complication after esophagectomy and associated with increased post-operative morbidity and mrotality. The aim of this study was to evaluate the management of leakage after robot-assisted minimally invasive esophagectomy (RAMIE) with intrathoracic anastomosis. From a single center prospectively maintained database, all patients with anastomotic leakages defined by the Esophageal Complications Consensus Group between 2016 and 2021 were included. Contained leakage was defined as presence of air or fluid at level of the anastomosis without the involvement of the mediastinum or thorax. Non-contained leakage was defined as mediastinitis and/or mediastinal/pleural fluid collections. The primary outcome was 90-day mortality and the secondary outcome was successful recovery. In this study, 40 patients with anastomotic leakage were included. The 90-day mortality rate was 3% (n = 1). Leakage was considered contained in 29 patients (73%) and non-contained in 11 patients (27%). In the contained group, the majority of the patients were treated non-surgically (n = 27, 93%) and management was successful in 22 patients (76%). In the non-contained group, all patients required a reoperation with thoracic drainage and management was successful in seven patients (64%). Management failed in 11 patients (28%) of whom 7 developed an esophagobronchial fistula, 3 had a disconnection of the anastomosis and 1 died of a septic bleeding. In conclusion, this study demonstrates that the management anastomotic leakage in patients who underwent RAMIE with an intrathoracic anastomosis was successful in 73% of the patients with a 90-day mortality rate of 3%. A differentiated approach for the management of intrathoracic anastomotic leakage is proposed.

Management of intra-thoracic anastomotic leakages after esophagectomy: updated systematic review and meta-analysis of endoscopic vacuum therapy versus stenting

Despite a significant decrease of surgery-related mortality and morbidity, anastomotic leakage still occurs in a significant number of patients after esophagectomy. The two main endoscopic treatments in case of anastomotic leakage are self-expanding metal stents (SEMS) and the endoscopic vacuum therapy (EVT). It is still under debate, if one method is superior to the other. Therefore, we performed a systematic review and meta-analysis of the existing literature to compare the effectiveness and the related morbidity of SEMS and EVT in the treatment of esophageal leakage. We systematically searched for studies comparing SEMS and EVT to treat anastomotic leak after esophageal surgery. Predefined endpoints including outcome, treatment success, endoscopy, treatment duration, re-operation rate, intensive care and hospitalization time, stricture rate, morbidity and mortality were assessed and included in the meta-analysis. Seven retrospective studies including 338 patients matched the inclusion criteria. Compared to stenting, EVT was significantly associated with higher healing (OR 2.47, 95% CI [1.30 to 4.73]), higher number of endoscopic changes (pooled median difference of 3.57 (95% CI [2.24 to 4.90]), shorter duration of treatment (pooled median difference − 11.57 days; 95% CI [− 17.45 to − 5.69]), and stricture rate (OR 0.22, 95% CI [0.08 to 0.62]). Hospitalization and intensive care unit duration, in-hospital mortality rate, rate of major and treatment related complications, of surgical revisions and of esophago-tracheal fistula failed to show significant differences between the two groups. Our analysis indicates a high potential for EVT, but because of the retrospective design of the included studies with potential biases, these results must be interpreted with caution. More robust prospective randomized trials should further investigate the potential of the two procedures.

Is Prophylactic Cervical Drainage Effective in Patients Undergoing McKeown Esophagectomy Reconstructed Through the Retrosternal Route with Two-Field Lymphadenectomy?

BACKGROUND

McKeown esophagectomy with two-field lymphadenectomy is the treatment of choice for oncologic esophagectomy. A cervical drain is placed in cases after modern two-field lymph node dissection (M2FD) to provide information on anastomotic leakage. However, the necessity of prophylactic cervical drainage during surgery remains unknown. This study aimed to clarify the clinical significance of cervical drainage in patients who underwent McKeown esophagectomy with M2FD.

METHODS

A total of 293 patients underwent McKeown surgery with two-field lymphadenectomy at our institute between January 2013 and December 2019. We compared the day of drain removal, amount of drainage volume, and the appearance of drainage fluid between patients with and without anastomotic leakage.

RESULTS

McKeown esophagectomy reconstructed through the retrosternal route is 203 patients (69.3%) of all. Nineteen patients (6.5%) experienced anastomotic leakage. The amount of cervical drain discharge was comparable between patients with and without anastomotic leakage. In addition, no purulent or salivary discharge was observed in patients with anastomotic leakage. There was no difference in the median day of drain removal between the groups. The initial clinical findings for the diagnosis of anastomotic leakage were surgical site infection in 10 (52.6%), fever in 5 (26.3%), prolonged inflammation in a blood test in 3 (15.8%), and bloody discharge from the chest tube in 1 (5.3%). There was no mortality due to any cause.

CONCLUSION

A prophylactic cervical drain may not be mandatory in patients with esophageal cancer undergoing McKeown esophagectomy reconstructed through the retrosternal route with two-field lymphadenectomy.

Management of refractory cervical anastomotic fistula after esophagectomy using the pectoralis major myocutaneous flap

INTRODUCTION

A refractory cervical anastomotic fistula which postoperatively remains unhealed for more than 2 months under conservative care severely impacts the quality of life of the patient and potentially leads to anastomotic stricture after the fistula heals. It is widely accepted that, to avoid this complication, refractory cervical anastomotic fistulas should undergo more aggressive treatments. However, when and which surgical intervention should be considered is unclear.

OBJECTIVE

This study was designed to evaluate the role of the pectoralis major myocutaneous flap in the management of refractory cervical anastomotic fistulas based on our experience of 6 cases and a literature review.

METHODS

Six patients diagnosed with refractory cervical anastomotic fistula after esophagectomy treated using pectoralis major myocutaneous flap transfer were included in the study. The clinical data, surgical details, and treatment outcome were retrospectively analyzed.

RESULTS

All patients survived the operations. One patient who had a circumferential anastomotic defect resulting from surgical exploration developed a mild fistula in the neo-anastomotic site in the 5th postoperative day, which healed after 7 days of conservative care. This patient developed an anastomotic stricture which was partially alleviated by an endoscopic anastomotic dilatation. All the other 5 patients had uneventful recoveries after operations and restored oral intake on the 10th-15th days after operation, and they tolerated normal diets without subsequent sequelae on follow-up. One patient developed both local and lung recurrence and died in 15 months after operation, while the other 5 patients survived with good tumor control during the follow-up of 25-53 months.

CONCLUSION

The satisfactory treatment outcome in our study demonstrates that pectoralis major myocutaneous flap reconstruction is a reliable management modality for refractory cervical anastomotic fistulas after esophagectomy, particularly for those patients who experienced persistent fistulas after conservative wound care and repeated wound closures.

Endoscopic vacuum therapy for anastomotic leak after esophagectomy: a single-center's early experience

Anastomotic leak is a serious complication after esophagectomy. Endoscopic vacuum therapy (EVT) has become increasingly popular in treating upper gastrointestinal anastomotic leaks over the last years. We are here reporting our current complete experience with EVT as primary treatment for anastomotic leak following esophagectomy. This is a retrospective study analyzing all patients with EVT as primary treatment for anastomotic leak after esophagectomy between November 2016 and January 2020 at Karolinska University Hospital, Sweden. The primary endpoint was anastomotic fistula healing with EVT only. Twenty-three patients primarily treated with EVT after anastomotic leak following esophagectomy were included. Median duration of EVT was 17 days (range 5-56) with a median number of 3 (range 1-14) vacuum sponge changes per patient. A total number of 95 vacuum sponges were placed in the entire cohort, of which 93 (97.9%) were placed intraluminally and 2 (2.1%) extraluminally. The median changing time interval of sponges was 5 days (range 2-8). Successful fistula healing was achieved in 19 of 23 patients (82.6%), of which 17 (73.9%) fistulas healed with EVT only. There were 2 (8.7%) airway fistulas following EVT. No other adverse events occurred. Three patients (13%) died in-hospital. In conclusion EVT seems to be a safe and feasible therapy option for anastomotic leak following esophagectomy. The effect of EVT on the risk for development of airway fistulas needs to be addressed in future studies and until more data are available care should be taken regarding sponge positioning as well as extended treatment duration.

Endoscopic vacuum therapy versus stent treatment of esophageal anastomotic leaks (ESOLEAK): study protocol for a prospective randomized phase 2 trial

BACKGROUND

Intrathoracic anastomotic leaks represent a major complication after Ivor Lewis esophagectomy. There are two promising endoscopic treatment strategies in the case of leaks: the placement of self-expanding metal stents (SEMS) or endoscopic vacuum therapy (EVT). Up to date, there is no prospective data concerning the optimal endoscopic treatment strategy. This is a protocol description for the ESOLEAK trial, which is a first small phase 2 randomized trial evaluating the quality of life after treatment of anastomotic leaks by either SEMS placement or EVT.

METHODS

This phase 2 randomized trial will be conducted at two German tertiary medical centers and include a total of 40 patients within 2 years. Adult patients with histologically confirmed esophageal cancer, who have undergone Ivor Lewis esophagectomy and show an esophagogastric anastomotic leak on endoscopy or present with typical clinical signs linked to an anastomotic leak, will be included in our study taking into consideration the exclusion criteria. After endoscopic verification of the anastomotic leak, patients will be randomized in a 1:1 ratio into two treatment groups. The intervention group will receive EVT whereas the control group will be treated with SEMS. The primary endpoint of this study is the subjective quality of life assessed by the patient using a systematic and validated questionnaire (EORTC QLQ C30, EORTC QLQ-OES18 questionnaire). Important secondary endpoints are healing rate, period of hospitalization, treatment-related complications, and overall mortality.

DISCUSSION

The latest meta-analysis comparing implantation of SEMS with EVT in the treatment of esophageal anastomotic leaks suggested a higher success rate for EVT. The ESOLEAK trial is the first study comparing both treatments in a prospective manner. The aim of the trial is to find suitable endpoints for the treatment of anastomotic leaks as well as to enable an adequate sample size calculation and evaluate the feasibility of future interventional trials. Due to the exploratory design of this pilot study, the sample size is too small to answer the question, whether EVT or SEMS implantation represents the superior treatment strategy.

Outcomes of Esophageal Stent Therapy for the Management of Anastomotic Leaks

BACKGROUND

The purpose of this study was to present the optimal patient selection for esophageal stenting after esophageal resection to investigate possible factors leading to treatment success or treatment failure in these patients.

METHODS

This was a prospective, observational study of patients from January 2005 to May 2019 with an esophageal anastomotic leak that were treated with a self-expandable stent (SES).

RESULTS

A total of 34 patients were treated. All achieved technical success (100%); 33 (97%) achieved clinical success. No patient had to have reoperative surgery based on their leak management. The stenting in-hospital mortality was 0% with 1 patient (2%) with a 90-day mortality from possible leak-related death. Patients had their stents removed with a median of 106 days.

CONCLUSIONS

Stenting for an anastomotic leak after resection offers a safe and effective method of treatment and is successful in the majority of cases. Critical to success is optimal patient selection, adequate leak drainage, and optimal stent selection and placement.

Anastomotic leak following oesophagectomy: research priorities from an international Delphi consensus study

BACKGROUND

The Oesophago-Gastric Anastomosis Audit (OGAA) is an international collaborative group set up to study anastomotic leak outcomes after oesophagectomy for cancer. This Delphi study aimed to prioritize future research areas of unmet clinical need in RCTs to reduce anastomotic leaks.

METHODS

A modified Delphi process was overseen by the OGAA committee, national leads, and engaged clinicians from high-income countries (HICs) and low/middle-income countries (LMICs). A three-stage iterative process was used to prioritize research topics, including a scoping systematic review (stage 1), and two rounds of anonymous electronic voting (stages 2 and 3) addressing research priority and ability to recruit. Stratified analyses were performed by country income.

RESULTS

In stage 1, the steering committee proposed research topics across six domains: preoperative optimization, surgical oncology, technical approach, anastomotic technique, enhanced recovery and nutrition, and management of leaks. In stages 2 and stage 3, 192 and 171 respondents respectively participated in online voting. Prioritized research topics include prehabilitation, anastomotic technique, and timing of surgery after neoadjuvant chemo(radio)therapy. Stratified analyses by country income demonstrated no significant differences in research priorities between HICs and LMICs. However, for ability to recruit, there were significant differences between LMICs and HICs for themes related to the technical approach (minimally invasive, width of gastric tube, ischaemic preconditioning) and location of the anastomosis.

CONCLUSION

Several areas of research priority are consistent across LMICs and HICs, but discrepancies in ability to recruit by country income will inform future study design.

Critical Appraisal of the Impact of Oesophageal Stents in the Management of Oesophageal Anastomotic Leaks and Benign Oesophageal Perforations: An Updated Systematic Review

INTRODUCTION

Endoscopic placement of oesophageal stents may be used in benign oesophageal perforation and oesophageal anastomotic leakage to control sepsis and reduce mortality and morbidity by avoiding thoracotomy. This updated systematic review aimed to assess the safety and effectiveness of oesophageal stents in these two scenarios.

METHODS

A systematic literature search of all published studies reporting use of metallic and plastic stents in the management of post-operative anastomotic leaks, spontaneous and iatrogenic oesophageal perforations were identified. Primary outcomes were technical (deploying ≥ 1 stent to occlude site of leakage with no evidence of leakage of contrast within 24-48 h) and clinical success (complete healing of perforation or leakage by placement of single or multiple stents irrespective of whether the stent was left in situ or was removed). Secondary outcomes were stent migration, perforation and erosion, and mortality rates. Subgroup analysis was performed for plastic versus metallic stents and anastomotic leaks versus perforations separately.

RESULTS

A total of 66 studies (n = 1752 patients) were included. Technical and clinical success rates were 96% and 87%, respectively. Plastic stents had significantly higher migration rates (24% vs 16%, p = 0.001) and repositioning (11% vs 3%, p < 0.001) and lower technical success (91% vs 95%, p = 0.032) than metallic stents. In patients with anastomotic leaks, plastic stents were associated with higher stent migration (26% vs 15%, p = 0.034), perforation (2% vs 0%, p = 0.013), repositioning (10% vs 0%, p < 0.001), and lower technical success (95% vs 100%, p = p = 0.002). In patients with perforations only, plastic stents were associated with significantly lower technical success (85% vs 99%, p < 0.001).

CONCLUSIONS

Covered metallic oesophageal stents appear to be more effective than plastic stents in the management of oesophageal perforation and anastomotic leakage. However, quality of evidence of generally poor and high-quality randomised trial is needed to further evaluate best management option for oesophageal perforation and anastomotic leakage.

Evolution of Esophagectomy for Cancer Over 30 Years: Changes in Presentation, Management and Outcomes

Background

Esophageal cancer has seen a considerable change in management and outcomes over the last 30 years. Historically, the overall prognosis has been regarded as poor; however, the use of multimodal treatment and the integration of enhanced recovery pathways have improved short- and long-term outcomes.

Objective

The aim of this study was to evaluate the changing trends in presentation, management, and outcomes for patients undergoing surgical treatment for esophageal cancer over 30 years from a single-center, high-volume unit in the UK.

Patients and Methods

Data from consecutive patients undergoing esophagectomy for cancer (adenocarcinoma or squamous cell carcinoma) between 1989 and 2018 from a single-center, high-volume unit were reviewed. Presentation method, management strategies, and outcomes were evaluated. Patients were grouped into successive 5-year cohorts for comparison and evaluation of changing trends.

Results

Between 1989 and 2018, 1486 patients underwent esophagectomy for cancer. Median age was 65 years (interquartile range [IQR] 59–71) and 1105 (75%) patients were male. Adenocarcinoma constituted 1105 (75%) patients, and overall median survival was 29 months (IQR 15–68). Patient presentation changed, with epigastric discomfort now the most common presentation (70%). An improvement in mortality from 5 to 2% (p < 0.001) was seen over the time period, and overall survival improved from 22 to 56 months (p < 0.001); however, morbidity increased from 54 to 68% (p = 0.004).

Conclusions

Long-term outcomes have significantly improved over the 30-year study period. In addition, mortality and length of stay have improved despite an increase in complications. The reasons for this are multifactorial and include the use of perioperative chemo(radio)therapy, the introduction of an enhanced recovery pathway, and improved patient selection.

Management and outcomes of anastomotic leakage after McKeown esophagectomy: A retrospective analysis of 749 consecutive patients with esophageal cancer

PURPOSE

Cervical anastomotic leakages may manifest either cervically or intrathoracically. We retrospectively investigated the management strategies and clinical outcomes of patients who developed anastomotic leakages after McKeown esophagectomy and the spectrum of its clinical manifestations.

METHODS

Patients with esophageal cancer who underwent McKeown esophagectomy with cervical anastomosis (n = 749) between January 2015 and December 2018 were included.

RESULTS

Cervical anastomosis leakage was diagnosed in 53/749 (7.3%) patients. The leakage was primarily limited to cervical region in 16 (30.2%) patients, whereas intrathoracic spread was present in 37 (69.8%) patients. Intrathoracic manifestations were more commonly accompanied by fever (75.7% vs. 18.8%, P < 0.001) and leukocytosis than cervical manifestations (81.1% vs. 25.0%, P < 0.001). Compared to patients with cervical manifestations, those with intrathoracic manifestations had a longer duration of hospital stay (median; 58 vs. 40 days, P = 0.006) and higher incidence of tracheal fistula (21.6% vs. 0%, P = 0.045). Drainage through the neck wound was effective in all patients with cervical manifestations. Patients with intrathoracic manifestations who had transnasal inner drain or mediastinal drain placed intraoperatively achieved satisfactory drainage (27/37, 73.0%). Subsequent healing of anastomotic leaks was observed in 50 (94.3%) patients. There was no mortality associated with complications related to anastomotic leakage.

CONCLUSION

Intrathoracic manifestations of cervical anastomotic leakage are common in patients after McKeown esophagectomy. However, they are diagnosed later and are associated with more severe clinical consequences than cervical manifestations. Thus, a high index of suspicion and an early intervention policy for such anastomotic leaks should be adopted and strengthened to decrease the incidence of adverse clinical outcomes.

Anastomotic Leak Does Not Impact on Long-Term Outcomes in Esophageal Cancer Patients

Background

Esophagectomy is a technically demanding procedure associated with high levels of morbidity. Anastomotic leak (AL) is a common complication with potentially major ramifications for patients. It has also been associated with poorer long-term overall survival (OS) and disease recurrence.

Objective

The aim of this study was to determine whether AL contributes to poor OS and recurrence-free survival (RFS) for patients with esophageal cancer.

Methods

Consecutive patients undergoing a two-stage, two-field transthoracic esophagectomy from a single high-volume unit between 1997 and 2016 were evaluated. Clinicopathologic characteristics, along with oncological and postoperative outcomes, were stratified by no AL versus non-severe leak (NSL) versus severe esophageal AL (SEAL). SEAL was defined as ALs associated with Clavien–Dindo grade III/IV complications.

Results

This study included 1063 patients, of whom 8% (87/1063) developed AL; 45% of those who developed AL were SEALs (39/87). SEAL was associated with a prolonged critical care stay (median 8 vs. 3 vs. 2 days; p < 0.001) and prolonged hospital stay (median 43 vs. 27 vs. 15 days; p < 0.001) compared with NSL or no AL. There were no significant differences in number of lymph nodes harvested and rates of R1 resection between groups. OS and RFS were not affected by either NSL or SEAL, and Cox multivariate regression showed NSL and SEAL were not independently associated with OS and RFS. Sensitivity analysis in patients receiving neoadjuvant therapy followed by esophagectomy demonstrated similar findings.

Conclusion

These results demonstrate that AL leads to prolonged critical care and in-hospital length of stay; however, contrary to previous reports, our results do not compromise long-term outcomes and are unlikely to have a detrimental oncological impact.

Study protocol for a multicenter prospective cohort study on esophagogastric anastomoses and anastomotic leak (the Oesophago-Gastric Anastomosis Audit/OGAA)

Esophagectomy is a mainstay in curative treatment for esophageal cancer; however, the reported techniques and outcomes can vary greatly. Thirty-day mortality of patients with an intact anastomosis is 2-3% as compared to 17-35% in patients who have an anastomotic leak. The subsequent management of leaks postesophagectomy has great global variability with little consensus on a gold standard of practice. The aim of this multicentre prospective audit is to analyze current techniques of esophagogastric anastomosis to determine the effect on the anastomotic leak rate. Leak rates and leak management will be assessed to determine their impact on patient outcomes. A 12-month international multicentre prospective audit started in April 2018 and is coordinated by a team from the West Midlands Research Collaborative. This will include patients undergoing esophagectomy over 9 months and encompassing a 90-day follow-up period. A pilot data collection period occurred at four UK centers in 2017 to trial the data collection form. The audit standards will include anastomotic leak and the conduit necrosis rate should be less than 13% and major postoperative morbidity (Clavien-Dindo Grade III or more) should be less than 35%. The 30-day mortality rate should be less than 5% and the 90-day mortality rate should be less than 8%. This will be a trainee-led international audit of esophagectomy practice. Key support will be given by consultant colleagues and anesthetists. Individualized unit data will be distributed to the respective contributing sites. An overall anonymized report will be made available to contributing units. Results of the audit will be published in peer-reviewed journals with all collaborators fully acknowledged. The key information and results from the audit will be disseminated at relevant scientific meetings.

Non-placement versus placement of a drainage tube around the cervical anastomosis in McKeown esophagectomy: study protocol for a randomized controlled trial

BACKGROUND

Esophagectomy with extended lymphadenectomy remains the mainstay of treatment for localized esophageal cancer. Currently, transthoracic and abdominal esophagectomy with cervical anastomosis (McKeown esophagectomy) is a frequently used technique in Japan. However, cervical anastomosis is still an invasive procedure with a high incidence of anastomotic leakage. The use of a drainage tube to treat anastomotic leakage is effective, but the routine placement of a closed suction drain around the anastomosis at the end of the operation remains controversial. The objective of this study is to evaluate the postoperative anastomotic leakage rate, duration to oral intake, hospital stay, and analgesic use with nonplacement of a cervical drainage tube as an alternative to placement of a cervical drainage tube.

METHODS

This is an investigator-initiated, investigator-driven, open-label, randomized controlled parallel-group, noninferiority trial. All adult patients (aged ≥20 and ≤85 years) with histologically proven, surgically resectable (cT1-3 N0-3 M0) squamous cell carcinoma, adenosquamous cell carcinoma, or basaloid squamous cell carcinoma of the intrathoracic esophagus, and European Clinical Oncology Group performance status 0, 1, or 2 are assessed for eligibility. Patients (n = 110) with resectable esophageal cancer who provide informed consent in the outpatient clinic are randomized to either nonplacement of a cervical drainage tube (n = 55) or placement of a cervical drainage tube (n = 55). The primary outcome is the percentage of Clavien-Dindo grade 2 or higher anastomotic leakage.

DISCUSSION

This is the first randomized controlled trial comparing nonplacement versus placement of a cervical drainage tube during McKeown esophagectomy with regards to the usefulness of a drain for anastomotic leakage. If our hypothesis is correct, nonplacement of a cervical drainage tube will be recommended because it is associated with a similar anastomotic leakage rate but less pain than placement of a cervical drainage tube.

Application of Exercised-based Pre-rehabilitation in Perioperative Period of Patients with Gastric Cancer

Objective

To analyze the difference between exercised-based pre-rehabilitation and postoperative rapid rehabilitation of gastric cancer patients.

Methods

The clinical data of 120 patients who underwent surgical treatment between 2016 and 2018 in our hospital with pathologically confirmed gastric cancer were retrospectively reviewed. According to the different treatments during the perioperative period, they were divided into exercised-based pre-rehabilitation group and postoperative rapid rehabilitation group. Factor analysis was used to analyze pre-rehabilitation and postoperative rehabilitation of patients with gastric cancer after stress response, nutritional status, insulin resistance, and inflammatory response in patients with gastric cancer, and to further evaluate the value of pre-recovery accelerated postoperative recovery.

Results

The postoperative stress response, insulin resistance, and inflammatory response in the pre-rehabilitation group were lower than the conventional treatment group. The nutritional status was improved faster than the traditional treatment group. Exercised-based pre-rehabilitation for the rapid recovery of postoperative gastrointestinal function in patients with gastric cancer surgery has significant value.

Conclusion

Exercised-based pre-rehabilitation has great significance for the accelerated rehabilitation of patients with gastric cancer during perioperative period.

Comparison of Outcomes with Semi-mechanical and Circular Stapled Intrathoracic Esophagogastric Anastomosis following Esophagectomy

BACKGROUND

Several techniques have been described for esophagogastric anastomosis following esophagectomy. This study compared the outcomes of circular stapled anastomoses with semi-mechanical technique using a linear stapler.

METHODS

Perioperative data were extracted from a contemporaneously collected database of all consecutive esophagectomies for cancer with intrathoracic anastomoses performed in the Trent Oesophago-Gastric Unit between January 2015 and April 2018. Anastomotic techniques: circular stapled versus semi-mechanical, were evaluated and outcomes were compared. The primary outcome was anastomotic leak rate. Secondary outcomes included anastomotic stricture, overall complication rates, length of stay (LOS) and 30 day all-cause mortality.

RESULTS

One hundred and fifty-nine consecutive esophagectomies with intrathoracic anastomosis were performed during the study period. There were no significant differences between the two groups in terms of age, American Society of Anaesthesiologists score, Charlson comorbidity index and neoadjuvant therapies received. Circular stapled anastomoses were performed in 85 patients, while 74 patients received a semi-mechanical anastomosis. Clavien-Dindo complications II or more were higher in the circular stapled group (p = 0.02). There were 16 (10%) anastomotic leaks overall, three (4%) in semi-mechanical group versus 13 (15%) in the circular stapled group (p < 0.019). There was no statistically significant difference between the two groups in terms of LOS, 30-day mortality or the need for endoscopic dilatation of the anastomosis at 3 months follow-up.

CONCLUSION

The move from a circular stapled to a semi-mechanical intrathoracic anastomosis has been associated with a reduced postoperative anastomotic leak rate following esophagectomy for esophageal cancer.

Outcome of Self-Expanding Metal Stents in the Treatment of Anastomotic Leaks After Ivor Lewis Esophagectomy

BACKGROUND

Esophageal anastomotic leakages after Ivor Lewis esophagectomy are severe and life-threatening complications. We analyzed the outcome of using self-expanding metal stents (SEMS) in the treatment of postoperative leakage after esophagogastrostomy.

METHODS

Seventy patients with esophageal anastomotic leakage after Ivor Lewis esophagectomy for esophageal cancer who had received SEMS treatment between January 2006 and December 2015 at our clinic were identified in this retrospective study. The patients were analyzed according to demographic characteristics, risk factors, leakage characteristics, stent characteristics, stent-related complications, sealing success rate and mortality.

RESULTS

Over a 10-year period, 70 patients received SEMS as treatment for postoperative anastomotic leakage after esophagectomy. Technical success of esophageal stenting in anastomotic leakage was achieved in 50 out of 70 cases (71.4%). Sealing success rate was 70% (n = 49) with a median treatment of 28 days (range 7-87). In 20 patients (28.6%), stent-related complications, such as stenosis, dislocation, leakage persistence, perforation or esophagotracheal fistula occurred after the SEMS treatment. Sixty-one patients (87.1%) survived SEMS treatment of esophagogastric anastomotic leakage. Mean follow-up for all patients was 38 months (IQR 10-76), and no significant difference was found in a comparison of the long-term survival rate between patients with successful and unsuccessful SEMS treatment.

CONCLUSIONS

The management of esophageal anastomotic leaks after Ivor Lewis esophagectomy with SEMS is effective, safe and technically feasible. Aggressive non-surgical management should be considered when developing a treatment plan for stenting.

Reinforcement of intrathoracic oesophago-gastric anastomosis with fibrin sealant (Tisseel®) in oesophagectomy for cancer: A prospective comparative study

PURPOSE

Fibrin sealant (Tisseel) is a human protein and thrombin soluble fibrinogen that has been indicated for reinforcement of gastro-intestinal anastomoses to prevent leakage. The objective of this study is to examine the impact of fibrin sealant regarding anastomotic leak, following Ivor-Lewis procedure.

METHODS

This is a prospective comparative study on 2-stage oesophagectomy for cancer of the distal oesophagus or oesophagogastric junction. N = 57 individuals were randomly subjected; n = 22 patients to Tisseel in combination to surgical anastomosis versus n = 35 patients to surgical anastomosis alone. The test of probability was assessed through Chi-Square, independent samples paired T-Test and Log-Rank analysis.

RESULTS

Of the 57 cases included, 56 underwent hybrid and 1 open oesophagectomy. In the Tisseel group, n = 5(22.7%) developed anastomotic leak comparing to n = 3(8.6%) of the control group. No statistically significant difference in leak rate was shown between the two groups; the test of probability was rejected.

CONCLUSIONS

Our results are not supportive of Tisseel tissue sealing property on the intrathoracic oesophago-gastric anastomosis and fibrin sealant's use cannot be justified.

Thoracoscopy in prone position with two-lung ventilation compared to conventional thoracotomy during Ivor Lewis procedure: a multicenter case-control study

BACKGROUND

Intraoperative management based on thoracoscopy, prone position and two-lung ventilation could decrease the rate of postoperative pulmonary complications after esophagectomy. The aim of this study was to compare this multifaceted approach (MIE-PP) and conventional thoracotomy for Ivor Lewis procedure after a systematic laparoscopic dissection.

METHODS

Data from 137 consecutive patients undergoing Ivor Lewis procedures between 2010 and 2017 at two tertiary centers was analyzed retrospectively. The outcomes of patients who underwent MIE-PP (n = 58; surgeons group 1) were compared with those of patients undergoing conventional approach (n = 79; surgeons group 2). Our primary outcome was major postoperative pulmonary complications. Our main secondary outcomes were anastomotic leak, quality of resection and mortality.

RESULTS

Female patients were more prevalent in the MIE-PP group (p = 0.002). Other patient characteristics, cTNM staging and neoadjuvant treatment rate were not different between groups. Major postoperative pulmonary complications were significantly lower in the MIE-PP group compared to Conventional group (24 vs. 44%; p = 0.014). Anastomotic leak occurred in 31 versus 18% in MIE-PP group and Conventional groups, respectively (p = 0.103). Complete resection rate (98 vs. 95%; p = 0.303) and mean number of harvested lymph nodes (16 (4-40) vs. 18 (3-37); p = 0.072) were similar between the two groups. Postoperative mortality rates were 0 versus 2% at day 30 (p = 0.508) and 0 versus 7.6% at day 90 (p = 0.038).

CONCLUSION

Short-term outcomes of minimally invasive Ivor Lewis using thoracoscopy, prone position and two-lung ventilation are at least equivalent to the hybrid approach. Anastomotic leak after MIE-PP remains a major concern.

Incidence and treatment of mediastinal leakage after esophagectomy: Insights from the multicenter study on mediastinal leaks

BACKGROUND

Mediastinal leakage (ML) is one of the most feared complications of esophagectomy. A standard strategy for its diagnosis and treatment has been difficult to establish because of the great variability in their incidence and mortality rates reported in the existing series.

AIM

To assess the incidence, predictive factors, treatment, and associated mortality rate of mediastinal leakage using the standardized definition of mediastinal leaks recently proposed by the Esophagectomy Complications Consensus Group (ECCG).

METHODS

Seven Italian surgical centers (five high-volume, two low-volume) affiliated with the Italian Society for the Study of Esophageal Diseases designed and implemented a retrospective study including all esophagectomies (n = 501) with intrathoracic esophagogastric anastomosis performed from 2014 to 2017. Anastomotic MLs were defined according to the classification recently proposed by the ECCG.

RESULTS

Fifty-nine cases of ML were recorded, yielding an overall incidence of 11.8% (95%CI: 9.1%-14.9%). The surgical approach significantly influenced the occurrence of ML: the proportion of leakage was 10.5% and 9% after open and hybrid esophagectomy (HE), respectively, and doubled (20%) after totally minimally invasive esophagectomy (TMIE) (P = 0.016). No other predictive factors were found. The 30- and 90-d overall mortality rates were 1.4% and 3.2%, respectively; the 30- and 90-d leak-related mortality rates were 5.1% and 10.2%, respectively; the 90-d mortality rates for TMIE and HE were 5.9% and 1.8%, respectively. Endoscopy was the first-line treatment in 49% of ML cases, with the need for retreatment in 17.2% of cases. Surgery was needed in 44.1% of ML cases. Endoscopic treatment had the lowest mortality rate (6.9%). Removal of the gastric tube with stoma formation was necessary in 8 (13.6%) cases.

CONCLUSION

The incidence of ML after esophagectomy was high mainly in the TMIE group. However, the general and specific (leak-related) mortality rates were low. Early treatment (surgical or endoscopic) of severe leaks is mandatory to limit related mortality.

Management of anastomotic leaks following esophagectomy: when to intervene?

Background

Esophagectomy is the mainstay treatment for early stage and locoregionally advanced esophageal cancer. Anastomotic leaks following esophagectomy are associated with numerous detrimental sequelae. The management of anastomotic leaks has evolved over time. The present study is a single-institution experience of esophageal leak management over an 11-year period, in order to identify when these can be managed nonoperatively.

Methods

All patients undergoing esophagectomy with gastric reconstruction at our institution between 2004 and 2014 were identified. Preoperative patient characteristics and perioperative factors were reviewed. Failure of initial leak treatment was defined as need for escalation of therapy. Length of stay (LOS) and postoperative mortality were the primary outcomes. Follow-up was obtained through institutional medical records and the Social Security Death Index.

Results

Sixty-one of 692 (8.8%) patients developed an anastomotic leak. Forty-six patients (75.4%) first underwent observation, which was successful in 35 patients. Predictors of successful observation included higher preoperative albumin (P=0.02), leak diagnosed by esophagram (P=0.004), and contained leaks (P=0.01). Successful observation was associated with shorter LOS (P=0.001). Predictors of mortality included lower preoperative serum albumin (P=0.01) and induction therapy (P=0.03). Thirty and 90-day mortality among patients who developed an anastomotic leak were 9.8% and 16.7%, respectively.

Conclusions

Over half of anastomotic leaks were managed successfully with observation alone and did not require additional interventions. We have identified factors that may predict successful therapy with observation in these patients. Further research is warranted to determine more timely interventions for patients likely to fail conservative management.

Comparison of endoscopic vacuum therapy versus endoscopic stenting for esophageal leaks: systematic review and meta-analysis

Esophageal leaks remain a life-threatening postoperative complication of esophagectomy. Currently, self-expanding metal stents (SEMS) represent the endoscopic mainstay of treatment. Recently, endoscopic vacuum therapy (EVT) has emerged and shown promising results in these patients. We conducted an electronic systematic search using MEDLINE databases (PubMed, EMBASE, and Web of Science) looking for studies comparing EVT and SEMS for the treatment of esophageal leak and/or perforation. Four studies including 163 patients matched the inclusion criteria. Esophageal leak closure rate is significantly higher with EVT than SEMS [pooled odds ratio 5.51 (95% CI 2.11-14.88; P < 0.001)]. Additionally, EVT has a shorter treatment duration [pooled mean difference -9.0 days (95% CI 16.6-1.4; P = 0.021)], lower major complication (P = 0.011), and in-hospital mortality (P = 0.002) rate compared to SEMS. EVT for esophageal leak is feasible and safe. It has the potential to become the new gold standard in the endoscopic treatment of esophageal leaks and perforations. However, further comparative studies with SEMS are needed to strengthen the current evidence.

Diagnosis, assessment, and management of surgical complications following esophagectomy

Despite improvements in operative strategies for esophageal resection, anastomotic leaks, fistula, postoperative pulmonary complications, and chylothorax can occur. Our review seeks to identify potential risk factors, modalities for early diagnosis, and novel interventions that may ameliorate the potential adverse effects of these surgical complications following esophagectomy.

Role of self-expanding stents in the treatment of intrathoracic dehiscence after Ivor Lewis esophagectomy

INTRODUCTION

The role that self-expanding stents play in the treatment of dehiscence after transthoracic esophagectomy is not well defined and controversial. Our aim is to describe the experience in a tertiary care hospital using these devices for treating dehiscence after Ivor Lewis esophagectomy.

METHODS

Descriptive observational study of patients who suffered anastomotic dehiscence after a transthoracic esophagectomy, and especially those treated with stents, in the period between 2011-2016 at our hospital.

RESULTS

Ten patients (11.8%) presented anastomotic dehiscence. Eight patients received stents, one of them died due to causes unrelated to the device. Stent migration was observed in one case, and the devices were maintained an average of 47.3 days. The stent was not effective only in one patient who suffered early dehiscence due to acute ischemia of the stomach. The two patients who did not receive stents died after reoperation.

CONCLUSIONS

Stents are safe and effective devices that did not associate mortality in our series. They are especially indicated in intermediate or late-onset dehiscence and in fragile patients. The use of stents, together with mediastinal and pleural drainage, avoid reoperations with morbidity and mortality. Therefore, stents should be part of the usual therapeutic arsenal for the resolution of most suture dehiscences after Ivor Lewis esophagectomy. Randomized prospective studies would help to more precisely determine the role played by these devices in the treatment of dehiscence after transthoracic esophagectomy.

Outcomes following the main treatment options in patients with a leaking esophagus: a systematic literature review

Leakage from the esophagus and gastroesophageal junction can be lethal due to uncontrolled contamination of the mediastinum. The most predominant risk factors for the subsequent clinical outcome are the patients' delay as well as the delay of diagnosis. Two major therapeutic concepts have been advocated: either prompt closure of the leakage by insertion of a self-expandable metal stent (SEMS) or more traditionally, surgical exploration. The objective of this review is to carefully scrutinize the recent literature and assess the outcomes of these two therapeutic alternatives in the management of iatrogenic perforation-spontaneous esophageal rupture as separated from those with anastomotic leak. A systematic web-based search using PubMed and the Cochrane Library was performed, reviewing literature published between January 2005 and December 2015. Eligible studies included all studies that presented data on the outcome of SEMS or surgical exploration in case of esophageal leak (including >3 patients). Only patients older than 15 years of age by the time of admission were included. Articles in other languages but English were excluded. Treatment failure was defined as a need for change in therapeutic strategy due to uncontrolled sepsis and mediastinitis, which usually meant rescue esophagectomy with end esophagostomy, death occurring as a consequence of the leakage or development of an esophagorespiratory fistula and/or other serious life threatening complications. Accordingly, the corresponding success rate is composed of cases where none of the failures above occurred. Regarding SEMS treatment, 201 articles were found, of which 48 were deemed relevant and of these, 17 articles were further analyzed. As for surgical management, 785 articles were retrieved, of which 82 were considered relevant, and 17 were included in the final analysis. It was not possible to specifically extract detailed clinical outcomes in sufficient numbers, when we tried to separately analyze the data in relation to the cause of the leakage: i.e. iatrogenic perforation-spontaneous esophageal rupture and anastomotic leak. As for SEMS treatment, originally 154 reports focused on iatrogenic perforation, 116 focused on spontaneous ruptures, and only four described the outcome following trauma and foreign body management. Only five studies used a prospective protocol to assess treatment efficacy. Regarding a leaking anastomosis, 80 reports contained information about the outcome after treatment of esophagogastrostomies and 35 reported the clinical course after an esophagojejunostomy. An overall success rate of 88% was reported among the 371 SEMS-treated patients, where adequate data were available, with a reported in hospital mortality amounting to 7.5%. Regarding the surgical exploration strategy, the vast majority of patients had an attempt to repair the defect by direct or enforced suturing. This surgical approach also included procedures such as patching with pleura or with a diaphragmatic flap. The overall reported success rate was 83% (305/368) and the in-hospital mortality was 17% (61/368). The current literature suggests that a SEMS-based therapy can be successfully applied as an alternative therapeutic strategy in esophageal perforation rupture.

Evaluation of Anastomotic Leak after Esophagectomy for Esophageal Cancer: Typical Time Point of Occurrence, Mode of Diagnosis, Value of Routine Radiocontrast Agent Studies and Therapeutic Options

BACKGROUND

Data on the typical time point of occurrence of anastomotic leak (AL) after esophagectomy for esophageal cancer are currently scarce. Therefore, the usefulness of routine radiocontrast agent studies (RRCS) for testing proper healing of the anastomosis after esophagectomy remains unclear. Furthermore, preferred available tools to diagnose postoperative AL and therapeutic options are still under debate.

METHODS

We present a retrospective analysis of 328 consecutive patients who underwent esophagectomy for esophageal cancer between 2005 and 2015. A RRCS has been performed to date in our center on the fifth postoperative day (POD), before returning to normal oral intake.

RESULTS

In total, 49 of 328 patients developed AL after esophagectomy (15%). A total of 11 patients (23%) developed AL before the RRCS and 34 patients (69%) after an unremarkable RRCS; and 4 patients (8%) with AL were diagnosed by RRCS, resulting in overall sensitivity of 16%. The median time point of occurrence of AL was POD 9, the majority of AL (84%) occurred between POD 1 and 19. Computed tomography led to the diagnosis of AL in 41% of patients. The most frequent therapy of AL was stenting in 47% of patients. Endoscopic vacuum therapy was used in 4 patients.

CONCLUSIONS

The majority of AL occurred within the first 3 weeks after esophagectomy without a typical time point. In our series, RRCS on the fifth POD had a low sensitivity of 16%. Therefore, standardized RRCS and fasting till the examination cannot be generally recommended. In case of clinical suspicion of AL, computed tomography of the chest and abdomen with oral contrast agent should be performed, followed by endoscopy. Endoscopic stent placement remains the standard therapy of AL in our center. Endoscopic vacuum therapy evolves as it is an interesting alternative therapeutic option and can be combined with stenting in selected cases.

Significant decrease of mortality due to anastomotic leaks following esophageal resection: management makes the difference

PURPOSE

Anastomotic leakage is the most frequent cause of postoperative mortality following esophageal surgery. However, no gold standard for diagnosing and managing leakage has been established. Continuous clinical judgment is extremely important; therefore, to optimize the management of leakage, we established a special group for decision-making in cases of suspected leakage in the early postoperative period.

METHODS

Between January 2010 and December 2016, 234 consecutive patients underwent elective esophageal resection with a thoracoabdominal incision. In 2014, we established a group consisting of a surgeon, surgical endoscopist, and anesthesiologist for decision-making in cases of suspected leakage. They discussed emerging problems and decided on further diagnostics or therapy. The data were documented prospectively and compared to the years prior to 2014.

RESULTS

Two hundred and thirty-four consecutive patients were enrolled in the study, 110 in the years 2010-2013 (group A), and 124 in the years 2014-2016 (group B). Neither patients' characteristics nor the rate of anastomotic leakage differed significantly between the two study groups. The hospital mortality rate was 10% (11 patients) in group A and 4.8% (six patients) in group B. Most interestingly, mortality due to anastomotic leakage was 35% in group A (9/26), whereas it decreased significantly to 6.5% (2/31 patients) (P < 0.001) in group B.

CONCLUSIONS

Our data clearly demonstrated that optimizing the management of anastomotic leakage by making team decisions can lead to a significant decrease in mortality.
