Complex Esophageal Reconstruction Procedures Have Acceptable Outcomes Compared With Routine Esophagectomy

Systematic review of free jejunal flap for secondary esophageal reconstruction

INTRODUCTION

Esophagus reconstruction could be complicated by leakage, stenosis or graft loss. Salvage surgery may be needed in case of failure of endoscopic treatment or large esophagus defect. Although free jejunal flap is admitted for salvage head and neck reconstruction, few reports assess the results of free jejunal interposition in salvage esophagus reconstruction. We undertook a systematic review whose primary aim is to investigate outcomes of secondary esophageal reconstruction with free jejunal flap in terms of mortality, complications and functional results.

MATERIAL AND METHOD

We conducted a systematic review of the literature according to the PRISMA 2020 statements searching PubMed and Scopus databases for articles assessing free jejunal flap for secondary reconstruction after failed esophagus reconstruction. References of included studies were also screened. Studies quality was assessed using the JBI Critical Appraisal tools.

RESULTS

562 studies were yielded through databases search and 328 studies were yielded through citations search. 18 articles were included in the systematic review corresponding to a total of 62 patients from 3 to 76 years old. All studies were level of evidence IV case reports or case series. We found that overall mortality was 3.2%, anastomotic fistula rate was 21%, anastomotic stricture rate was 4.8% and graft loss rate was 9.7% with survival of all jejunal regrafts. Solid oral intake was achieved in 93.0% of cases.

CONCLUSION

Jejunal free flap is a pertinent option for secondary esophageal reconstruction but remains a challenging surgery with high risk of complications that requires multidisciplinary team in large volume/tertiary care hospitals.

Beware of gastric tube in esophagectomy after gastric radiotherapy: A case report

BACKGROUND

Gastric tube formation and pull-up is the most common technique of reconstruction following esophagectomy for esophageal cancer. If previous treatment with radiotherapy for gastric mucosa-associated lymphoid tissue (MALT)-lymphoma restricts suitability of the stomach for anastomosis to the esophagus is unknown.

CASE SUMMARY

A 57-year-old man underwent sequential chemotherapy and radiotherapy for gastric MALT-lymphoma seven years prior to diagnosis of esophageal adenocarcinoma. Esophagectomy without neoadjuvant treatment was recommended by the multidisciplinary tumor board due to early tumor stage [uT1 (sm2) uN+ cM0 according to TNM-classification of malignant tumors, 8^th edition] without lymph node involvement. Minimal invasive esophageal resection with esophagogastrostomy was performed. Due to gastric tube necrosis with anastomotic leakage on the twelfth postoperative day, diverting resection with construction of a cervical salivary fistula was necessary. Rapid recovery facilitated colonic interposition without any complications six months afterwards.

CONCLUSION

This case report may represent the start for further investigation to know if it is reasonable to refrain from esophagogastrostomy in patients with a long interval between gastric radiotherapy and surgery.

Oesophageal reconstruction with a reversed gastric conduit for a complex oesophageal cancer patient: a case report

BACKGROUND

The gastric conduit is the best replacement organ for oesophageal reconstruction, but a reversed gastric conduit (RGC) is rare. Oesophageal reconstruction for oesophageal cancer patients with a previous history of complicated gastrointestinal surgery is rather difficult. Here, we report a case in which oesophageal reconstruction was successfully managed using RGC based solely on the left gastroepiploic artery supply.

CASE PRESENTATION

A 69-year-old man with oesophageal cancer had a history of endoscopic intestinal polypectomy and pylorus-preserving pancreaticoduodenectomy (PPPD). The right gastroepiploic artery and right gastric artery had been completely severed. The only supply artery that could be used for the gastric conduit was just the left gastroepiploic artery. Because of the complex history of abdominal surgery, we had no choice but to use the RGC to complete the oesophageal reconstruction, in which the gastric conduit was passed reversely through the hiatus to the oesophageal bed and layered end-to-side manual intrathoracic anastomosis with the esophagus. The patient had transient feeding problems with postoperative delayed thoracic stomach emptying but no anastomotic stenosis or thoracic stomach fistula. He was satisfied with his life and had no long-term complications. There was no significant effect on gut physiological function, and RGC could work normally.

CONCLUSIONS

Oesophageal reconstruction with RGC is a feasible procedure for complex oesophageal carcinoma that can simplify complicated surgical procedures, has less influence on gut function, is less invasive, and is safe.

Managing esophagocutaneous fistula after secondary gastric pull-up: A case report

BACKGROUND

Gastric pull-up (GPU) procedures may be complicated by leaks, fistulas, or stenoses. These complications are usually managed by endoscopy, but in extreme cases multidisciplinary management including reoperation may be necessary. Here, we report a combined endoscopic and surgical approach to manage a failed secondary GPU procedure.

CASE SUMMARY

A 70-year-old male with treatment-refractory cervical esophagocutaneous fistula with stenotic remnant esophagus after secondary GPU was transferred to our tertiary hospital. Local and systemic infection originating from the infected fistula was resolved by endoscopy. Hence, elective esophageal reconstruction with free-jejunal interposition was performed with no subsequent adverse events.

CONCLUSION

A multidisciplinary approach involving interventional endoscopists and surgeons successfully managed severe complications arising from a cervical esophago-cutaneous fistula after GPU. Endoscopic treatment may have lowered the perioperative risk to promote primary wound healing after free-jejunal graft interposition.

Laparoscopic-assisted Esophageal Bypass for T4b Esophageal Tumor as a Bridge to Definitive Therapy

BACKGROUND/AIM

Esophagobronchial fistula is a common complication of advanced esophageal cancer, related to respiratory distress and mortality. Esophageal bypass has been successfully utilized for palliation, as bridging to definitive chemoradiotherapy. The aim of this study is to present an extremely difficult case of a mid-esophageal squamous cell carcinoma complicated with aerodigestive fistula that was treated using 3D laparoscopic-assisted esophageal bypass with curative intent.

CASE REPORT

A 49-year-old female patient presented with T4b esophageal-squamous cell carcinoma and esophagobronchial fistula. Laparoscopic-assisted V-shaped retrosternal esophageal bypass using a gastric conduit was started, which was converted to open surgery due to respiratory distress. The patient was able to undergo chemoradiotherapy treatment.

CONCLUSION

3D laparoscopic-assisted esophageal bypass can be a safe and feasible approach in patients with advanced mid-esophageal squamous cell carcinoma and esophagobroncial fistula. Additionally to the advantages of laparoscopic surgery, this operation permits oral feeding, and can be used with possible curative intent in patients with adequate response to chemoradiotherapy.

Cardiac Surgery After Extraanatomic Esophageal Reconstruction: A Single Institution's Experience

BACKGROUND

Extraanatomic retrosternal and presternal esophageal reconstruction performed after esophagectomy poses a significant technical challenge to those patients who require cardiac surgery. This study reviewed a single-center experience with cardiac surgical procedures in patients with extraanatomic esophageal conduits, to examine the relative advantages of median sternotomy and thoracotomy approaches.

METHODS

This case series identified patients who underwent cardiac surgery after extraanatomic esophageal reconstruction between January 1, 1999 and October 1, 2019 at the Mayo Clinic in Rochester, Minnesota. Electronic medical records were reviewed for patient demographics, surgical indications, characteristics, and outcomes. Continuous variables were reported as the mean or as the median and range, as appropriate.

RESULTS

Seven individual patients had 8 cardiac surgical procedures after extraanatomic esophageal reconstruction (5 retrosternal, 2 presternal). All were male, with a median age of 65.5 years (range, 51 to 71 years). Preoperative computed tomography was obtained in all but 1 patient. Median sternotomy was performed in 4 patients, left thoracotomy in 2, right thoracotomy in 1, and right anterior thoracotomy in 1. Median bypass time was 91 minutes (interquartile range, 113.5 minutes). The median cross-clamp time was 57.5 minutes (interquartile range, 27.0 minutes). There was 1 delayed injury to a retrosternal conduit after median sternotomy approach. There were no injuries to the blood supply of any conduit. In-hospital mortality was 0%. The median length of stay was 7.5 days (range, 5 to 34 days).

CONCLUSIONS

Different cardiac surgical procedures can be performed safely in patients with extraanatomic esophageal reconstructions through median sternotomy or thoracotomy. Preoperative planning with computed tomography with intravenous contrast enhancement of the chest, abdomen, and pelvis is essential for individualization of the surgical approach.

Robotic Thoracic Surgery

Minimally invasive surgery for diseases of the chest offsets the morbidity of painful thoracic incisions while allowing for meticulous dissection of major anatomic structures. This benefit translates to improved outcomes and recovery following the surgical management of benign and malignant esophageal pathologic condition, mediastinal tumors, and lung resections. This anatomic region is particularly amenable to a robotic approach given the fixed space and need for complex intracorporeal dissection. As robotic platforms continue to evolve, more complex thoracic surgical interventions will be facilitated, translating to improved outcomes for our patients.

Robotic substernal esophageal bypass and reconstruction with gastric conduit-frequently overlooked minimally invasive option

Modern esophagectomy includes the esophageal extirpation with immediate reconstruction of the gastrointestinal (GI) continuity via posterior mediastinal route. In the majority of cases tubularized stomach is chosen as the conduit of choice. Other conduits, such as colon or small bowel can be used for these purposes as well. In rare circumstances use of the alternative route for the conduit placement is required. Authors describe the technique of robotic substernal esophageal bypass and reconstruction of the esophageal continuity.

Conduit necrosis following esophagectomy: An up-to-date literature review

Esophageal conduit ischaemia and necrosis is an uncommon but devastating complication of esophagectomy and remains one of the most challenging issues in surgical practice. The incidence, time interval to develop symptoms, and clinical presentation are highly variable with no predictable pattern. Evidence comes from case reports and case series rather than randomized controlled trials. We describe the issues surrounding conduit necrosis affecting the stomach, jejunum and colon as an esophageal replacement and the advantages, disadvantages and challenges of each type of reconstruction. Diagnosis is challenging for the most experienced surgeon. Upper gastrointestinal endoscopy and computed tomography thorax with both oral and intravenous contrast is the gold standard. Management, either conservative or interventional is also a difficult decision. Management options include conservative treatment and more aggressive treatments such as stent insertion, surgical debridement and repair of the esophagus using jejunum, colon or a musculocutaneous flap. In spite of recent advances in surgical techniques, there is no reliable strategy to manage esophageal conduit necrosis. Our review covers the pathophysiology and clinical significance of esophageal necrosis while highlighting current techniques of prevention, diagnosis and treatment of this life-threatening condition.

Identification of Risk Factors Associated With Postoperative Acute Kidney Injury After Esophagectomy for Esophageal Cancer

OBJECTIVE

To identify risks factors associated with acute kidney injury (AKI) after esophageal cancer surgery.

DESIGN

This was a retrospective study.

SETTING

Single academic center.

PARTICIPANTS

Subjects with non-metastatic esophageal cancer. Patients were excluded if they were younger than 18 years and had missing data.

MEASUREMENTS AND MAIN RESULTS

Primary outcome of the study was AKI according to AKI Network criteria. Demographic and perioperative variables were compared in patients with and without AKI. A multivariate Cox proportional model was used to assess the association between perioperative variables and AKI; p<0.05 was considered statistically significant. AKI was found in 107 (11.9%) of the 898 patients included in the study. The multivariate analysis also showed that BMI (odds ratio [OR] 1.07, 95% confidence interval [CI] 1.03-1.11), number of comorbidities (OR 1.52, 95% CI 1.20-1.93, p = 0.001), and preoperative creatinine concentrations (OR 2.37, 95% CI 1.14-4.92, p = 0.02) were independent predictors for AKI. The use of dexamethasone was associated with a reduced risk for AKI.

CONCLUSIONS

In support of previous reports in the literature, the authors found that AKI was not an uncommon complication after esophageal surgery. Obesity, cardiovascular comorbidities, and high preoperative concentrations were predictors of AKI. Dexamethasone administration during surgery appeared to have a protective effect. This finding opens an opportunity to further study in a randomized controlled trial the efficacy of dexamethasone in the prevention of AKI.
