The outcome of esophageal perforation in neonates and its risk factors: a 10-year study

PURPOSE

Esophageal perforation is a rare complication in infants that can be difficult to diagnose. The mortality rate due to esophageal perforation is high. This condition is more common in low birth weight premature infants. This study examines esophageal perforation in relation to various demographic and clinical variables.

METHODS

This study has a cross-sectional design. All pre-term neonates with esophageal perforation at Valiasr Hospital in Tehran, Iran, were included in the study over the span of ten years, from 2011 to 2021. Factors, such as gestational age, sex, weight, type of delivery, and interventions performed that could contribute to the condition, including intubation and Orogastric (OG) tube insertion, were investigated in the participants.

RESULTS

Among the 9924 infants studied over the 10-year period, 15 cases (0.15%) had esophageal perforation. All these infants underwent non-operative management with acceptable results.

CONCLUSION

 Learning about the risk factors for iatrogenic esophageal perforation in neonates can help prevent this unwanted event in most cases. Also, the majority of these cases can be managed non-operatively provided that early diagnosis is made.

Button Battery Ingestion in Children (PilBouTox®): A Prospective Study Describing the Clinical Course and Identifying Factors Related to Esophageal Impaction or Severe Cases

In this study, we aimed to identify the factors related to esophageal impaction following button battery (BB) ingestion in children. PilBouTox, a prospective multicentric observational cohort study, was conducted from French Poison Control Centers between June 1, 2016 and May 31, 2018. Children (0-12 years old) with BB ingestion were included. After ingestion, patients were monitored for 21 days or more if they remained symptomatic (maximum 1 year). Causes of ingestion, clinical manifestations, medical management, and the outcomes were recorded. In total, 415 patients were included; among them, 35 had esophageal impaction and 14 had severe complications or died. Seven symptoms were closely related (relative risk (RR) > 30) to esophageal impaction: anorexia, drooling, dyspnea, fever, hemodynamic instability, pallor, and pain. Furthermore, BBs > 15 mm were related to esophageal impaction (RR = 19, CI_95% [4.1; 88]). The absence of initial symptoms was a protective factor for esophageal impaction (RR = 0.013, CI_95% [0.002; 0.1]). Nine symptoms were closely related (RR > 30) to major effects and death: dyspnea, cough, dysphagia, drooling, fever, hemodynamic instability, pain, pallor, and vomiting. Seven symptoms were related to esophageal impaction and their rapid recognition could help to ensure that the patient is taken to a health care facility. Nine factors were related to the major effects of BB ingestion. We recommended an X-ray as soon as possible to determine the position of the BB.Trial Registry: Clinical Trial ID: NCT03708250, https://clinicaltrials.gov/ct2/show/NCT03708250.

Major adverse events related to endoscopic or laparoscopic procedures in achalasia. A systematic review and meta-analysis

INTRODUCTION AND AIMS

Surgical or endoscopic treatments play an essential role in the management of achalasia. The probability of adverse events in the performance of said treatments is a relevant aspect, when establishing the risk-benefit balance. The present study aimed to establish the association between serious adverse events and the performance of those procedures, in adult patients with achalasia.

MATERIALS AND METHODS

A systemic search of randomized and nonrandomized clinical trials, retrospective cohorts, and cases series on adult patients with achalasia that underwent laparoscopic Heller myotomy (LHM), peroral endoscopic myotomy (POEM), or endoscopic balloon dilation, that reported serious adverse events, was carried out on the Medline, CENTRAL, and EBSCO databases. Serious adverse events were defined as: death at 30 days, Clavien-Dindo grade III or higher classification, esophageal or gastric perforation, pneumothorax, mucosal tear, leakage, emphysema, pneumonia, and chest pain. The methodology included the PRISMA guidelines for reporting systematic reviews.

RESULTS

Thirty-five studies were found that reported information on 1,276 patients that underwent POEM, 5,492 that underwent LHM, and 10,346 that underwent endoscopic balloon dilation. The proportions of adverse events for the three techniques were 3.6, 4.9, and 3.1%, respectively.

DISCUSSION AND CONCLUSIONS

The 3 therapeutic interventions evaluated had similar proportions of adverse events. There were few reports of death at 30 days as an outcome and the lack of standardization in reporting adverse events in the studies analyzed was prominent.

Surgical treatment of esophageal perforation after stereotactic body radiotherapy: A report of two cases

INTRODUCTION AND IMPORTANCE

Esophageal perforation due to stereotactic body radiotherapy (SBRT) is rare, and there is no consensus on the treatment strategy. Here, we report two cases of esophageal perforation caused by CyberKnife irradiation managed with distinct surgical approaches.

CASE PRESENTATION

Case 1 was a 54-year-old woman who was administered chemotherapy including bevacizumab and underwent CyberKnife SBRT for postoperative ovarian cancer (pStage IIIc) with metastasis in the eighth thoracic vertebra. Thirteen months after irradiation, she suddenly developed right back and anterior thoracic pain and was diagnosed with esophageal perforation. Despite open chest drainage and intercostal muscle (ICM) flap coverage, the fistula could not be closed, leading to pyogenic spondylitis and epidural abscess. Case 2 was of a 58-year-old woman with mediastinal lymph node metastasis 5 years after uterine cancer surgery (pStage Ia) who underwent CyberKnife SBRT. Six months after irradiation, she experienced back pain and was diagnosed with esophageal perforation. After curative esophagectomy, the patient was discharged on postoperative day 22 without any adverse effects.

CLINICAL DISCUSSION

Esophageal perforation by SBRT with vascular endothelial growth factor inhibitors (VEGFI) such as bevacizumab has rarely been reported. Considering the impaired wound healing system and blood perfusion caused by radiation therapy and VEGFI, difficulty closing the perforation covered with an ICM flap was hypothesized.

CONCLUSION

Late esophageal toxicity from irradiation may cause impaired blood flow and wound healing; therefore, curative esophagectomy, including at the perforation site, is effective.

Esophageal perforations - a population-based nationwide study in Sweden with survival analysis

BACKGROUND

Esophageal perforation is a rare and life-threatening condition with several treatment options. The aim was to assess the incidence, type of treatment and mortality of esophageal perforations in Sweden and to identify risk factors for 90-day mortality.

METHOD

All patients admitted with an esophageal perforation from 2007 to 2017 were identified from the National Patient Register. Mortality was assessed by linkage with the Cause of Death Registry. We analyze the incidence and the impact of age, sex, comorbidities on mortality.

RESULTS

879 patients with esophageal perforation were identified, giving an incidence rate of 1.09 per 100,000 person-years. The median age at diagnosis was 68.8 years and 60% were men. The mortality was 26% at 90 days. Independent risk factors for death within 90 days were age (odds ratio (OR): 6.20; 95% (confidence interval) CI: 2.16-17.79 at 60-74 years and OR: 11.58; 95% CI: 4.04-33.15 at 75 years or older), peripheral vascular disease (OR: 2.92; 95% CI: 1.44-5.92) and underlying malignant disease (OR: 5.91; 95% CI: 3.86-9.03). In patients younger than 45 years, survival was lower among women than among men (at 5 years 73 and 93%, respectively). The cause of death among young women was often drug-related or suicide.

CONCLUSIONS

90-day mortality was 26%, old age, vascular disease and underlying malignant disease were risk factors.

Delayed Endoscopic Management of Esophageal Sharp-Pointed Food Impaction: An Analysis of 829 Cases in China

BACKGROUND

Esophageal foreign body impaction is the most common cause of endoscopic emergency. However, there are limited available data on delayed endoscopic management of esophageal sharp-pointed food impaction.

AIMS

To investigate cases of esophageal sharp-pointed food impaction with endoscopic removal findings.

METHODS

This single-center retrospective study collected medical records to identify patients with esophageal sharp-pointed food impaction who underwent endoscopic removal between April 2018 and April 2020. The patients were divided into the early (endoscopic removal <12 h) and delayed intervention (>12 h) cohorts.

RESULTS

Overall, 133 and 696 patients received early and delayed intervention, respectively. The success rate of endoscopic foreign body removal was 96.45%. The most common foreign body was fish bone (66.90%), and the most common shape was "I" (56.26%). Patients from the delayed intervention cohort received general anesthesia with a higher risk for perforation, and no foreign body was identified. The duration of endoscopy, distance between the foreign body/wound and the incisor, and longest diameter of the foreign body were not different between the groups. In multivariate analysis, male sex (odds ratio = 1.792 [1.159, 2.771]; P = 0.009), longer duration of impaction (odds ratio = 2.212 [1.121, 4.365]; P = 0.022) and endoscopy (odds ratio = 1.502 [1.253, 1.800]; P < 0.001), and longest diameter of the foreign body (odds ratio = 1.632 [1.329, 2.003]; P < 0.001) were associated with a higher incidence of perforation in patients with foreign body impaction.

CONCLUSIONS

Endoscopic removal is a safe and effective treatment method for sharp-pointed food impaction. Delayed endoscopic removal can increase the risk of esophageal perforation.

Factors affecting perforation of the esophagus in patients with deep neck infection

Background

Deep neck infection (DNI) is a serious disease that can lead to severe morbidity, including esophageal perforation, and mortality. However, no previous study has explored the risk factors associated with esophageal perforation in patients with DNI. This study investigated these factors.

Methods

Between September 2015 and September 2021, 521 patients with DNI were studied. Relevant clinical variables and deep neck spaces were assessed.

Results

In a multivariate analysis, involvement of the retropharyngeal space (OR 5.449, 95% CI 1.603–18.51, p = 0.006) and the presence of mediastinitis (OR 218.8, 95% CI 55.98–855.3, p < 0.001) were independent risk factors associated with esophageal perforation in patients with DNI.

There were no differences in pathogens between 32 patients with and 489 patients without esophageal perforation (all p > 0.05).

Conclusion

Involvement of the retropharyngeal space and the presence of mediastinitis were independent risk factors associated with esophageal perforation in patients with DNI. There were no differences in pathogens between the groups with and without esophageal perforation in DNI.

Endoscopic vacuum therapy in the upper gastrointestinal tract: when and how to use it

BACKGROUND

Endoscopic vacuum therapy (EVT) has emerged as a novel treatment option for upper gastrointestinal wall defects. The basic principle of action of EVT entails evacuation of secretions, removal of wound debris, and containment of the defect. Furthermore, there is increasing evidence that EVT reduces interstitial edema, increases oxygen saturation, and promotes tissue granulation and microcirculation. Various devices, such as macroporous polyurethane sponge systems or open-pore film drains, have been developed for specific indications. Depending on the individual situation, EVT devices can be placed in- or outside the intestinal lumen, as a stand-alone procedure, or in combination with surgical, radiological, and other endoscopic interventions.

PURPOSE

The aim of this narrative review is to describe the current spectrum of EVT in the upper gastrointestinal tract and to assess and summarize the related scientific literature.

CONCLUSIONS

There is growing evidence that the efficacy of EVT for upper GI leakages exceeds that of other interventional treatment modalities such as self-expanding metal stents, clips, or simple drainages. Owing to the promising results and the excellent risk profile, EVT has become the therapy of choice for perforations and anastomotic leakages of the upper gastrointestinal tract in many centers of expertise. In addition, recent clinical research suggests that preemptive use of EVT after high-risk upper gastrointestinal resections may play an important role in reducing postoperative morbidity.

Is thoracic esophagostomy an option in esophageal perforation in pediatric patients?

Esophagostomy and subsequent esophagectomy are extremely rare operations in the management of benign esophageal perforations in children. In this report, we present a 20-month-old female in whom we performed thoracic esophagostomy and subsequent intrathoracic esophagogastric anastomosis due to esophageal perforation caused by a chronic foreign body. The patient was discharged on the 10th postoperative day, and no complications were observed in the patient, who was followed for four years. The thoracic esophagostomy procedure helps preserve the esophageal length and easy execution of the esophagogastric anastomosis in the thorax. We believe it can be a safe and useful technique in carefully selected cases.

Endoscopic extraction of a submucosal esophageal foreign body piercing into the thoracic aorta: A case report

BACKGROUND

Aorto-esophageal injury is a rare but life-threatening complication of esophageal foreign bodies, which typically requires open surgery. The best way to treat patients with this condition remains unclear. To date, few reports have described an aortic wall directly penetrated by a sharp foreign body. Here, we present a rare case of a fishbone completely embedded in the esophageal muscularis propria and directly piercing the aorta, which was successfully treated by endoscopy and thoracic endovascular aortic repair (TEVAR).

CASE SUMMARY

We report the case of a 71-year-old man with a 1-d history of retrosternal pain after eating fish. No abnormal findings were observed by the emergency esophagoscopy. Computed tomography showed a fishbone that had completely pierced through the esophageal mucosa and into the aorta. The patient refused to undergo surgery for personal reasons and was discharged. Five days after the onset of illness, he was readmitted to our hospital. Endoscopy examination showed a nodule with a smooth surface in the middle of the esophagus. Endoscopic ultrasonography confirmed a fishbone under the nodule. After performing TEVAR, we incised the esophageal mucosa under an endoscope and successfully removed the fishbone. The patient has remained in good condition for 1 year.

CONCLUSION

Incising the esophageal wall under endoscope and extracting a foreign body after TEVAR may be a feasible option for cases such as ours.

Use of double-layered covered esophageal stents in post-surgical esophageal leaks and esophageal perforation: Our experience

INTRODUCTION

The use of esophageal stents for the endoscopic management of esophageal leaks and perforations has become a usual procedure. One of its limitations is its high migration rate. To solve this incovenience, the double-layered covered esophageal stents have become an option.

OBJECTIVES

To analyse our daily practice according to the usage of double-layered covered esophageal metal stents (DLCEMS) (Niti S™ DOUBLE™ Esophageal Metal Stent Model) among patients diagnosed of esophageal leak or perforation.

METHODS

Retrospective, descriptive and unicentric study, with inclusion of patients diagnosed of esophageal leak or perforation, from November 2010 until October 2018. The main aim is to evaluate the efficacy of DLCEMS, in terms of primary success and technical success. The secondary aim is to evaluate their (the DLCEMS) safety profile.

RESULTS

Thirty-one patients were firstly included. Among those, 8 were excluded due to mortality not related to the procedure. Following stent placement, technical success was reached in 100% of the cases, and primary success, in 75% (n=17). Among the complications, stent migration was present in 21.7% of the patients (n=5), in whom the incident was solved by endoscopic means.

CONCLUSIONS

According to our findings, DLCEMS represent an alternative for esophageal leak and perforation management, with a high success rate in leak and perforation resolutions and low complication rate, in contrast to the published data. The whole number of migrations were corrected by endoscopic replacement, without the need of a new stent or surgery.

Neck and mediastinal hematoma caused by a foreign body in the esophagus with diagnostic difficulties: A case report

BACKGROUND

Esophageal foreign body (FB) is a common clinical emergency. Clinically, computed tomography (CT) scans are important in the diagnosis of FBs in the esophagus. Here, we report a case of esophageal perforation and cervical hematoma, caused by a FB, whose uniqueness made rapid diagnosis difficult.

CASE SUMMARY

A 42-year-old man was transferred to our hospital with esophageal perforation, which was accompanied by cervical and mediastinal hematoma. CT scans only revealed a black shadow, approximately 2.5 cm in diameter, in the upper esophagus. After multidisciplinary discussion, he was quickly subjected to mediastinal hematoma resection, peripheral nerve compression release, esophageal FB removal and esophagectomy. Eventually, we removed a small crab with a pointed tip from his esophagus.

CONCLUSION

This was an unusual case of occurrence of sharp polygonal esophageal FBs caused by a small crab. Rapid diagnosis of this FB was difficult, mainly due to its translucent nature. Occurrence of sharp FBs, with cavities that sometimes only appear as black shadows on CT scans, can easily be mistaken for esophageal lumens. More attention should be paid to such sharp polygonal FBs.

Outcomes after hybrid minimally invasive treatment of Boerhaave syndrome: a single-institution experience

BACKGROUND

Spontaneous esophageal perforation or Boerhaave syndrome is a life-threatening emergency, associated with significant morbidity and mortality. In this retrospective series we describe our single-center experience with a hybrid minimally invasive treatment approach for the treatment of Boerhaave syndrome.

METHODS

Clinical data of all patients who presented with spontaneous esophageal rupture between January 2009 and December 2019 were analyzed. All patients underwent esophageal endoscopic stenting to seal the perforation and debridement of the contaminated mediastinal and pleural cavity through video-assisted thoracoscopic surgery (VATS). Primary outcome measure was defined as in-hospital death and 30-day mortality.

RESULTS

Twelve patients were included with a median age of 63 years (interquartile range [IQR] 51-74 years) of whom 58% (n = 7) were male. The median Pittsburg perforation severity score was 6.5 (IQR 6-9). Endoscopic reintervention was required in 8 patients (67%), primarily due to stent dislocation. In addition, 5 patients (42%) required re-VATS due to empyema formation. Thirty-day mortality and in-hospital mortality were respectively 17% (n = 2) and 25% (n = 3).

CONCLUSION

Endoscopic stenting in combination with thoracoscopic debridement is an effective and safe minimally invasive hybrid approach for the treatment of Boerhaave syndrome. This is depicted by the relatively low mortality rates, even among patients with high perforation severity scores. The relatively low mortality rates may be attributed to the combined approach of rapidly sealing the defect and decontamination of the thorax. Future studies should aim to corroborate this evidence which is limited by its sample size and retrospective nature.

Evolution of endoscopic vacuum therapy for upper gastrointestinal leakage over a 10-year period: a quality improvement study

BACKGROUND

Endoscopic vacuum therapy (EVT) is an effective treatment option for leakage of the upper gastrointestinal (UGI) tract. The aim of this study was to evaluate the clinical impact of quality improvements in EVT management on patients' outcome.

METHODS

All patients treated by EVT at our center during 2012-2021 were divided into two consecutive and equal-sized cohorts (period 1 vs. period 2). Over time several quality improvement strategies were implemented including the earlier diagnosis and EVT treatment and technical optimization of endoscopy. The primary endpoint was defined as the composite score MTL30 (mortality, transfer, length-of-stay > 30 days). Secondary endpoints included EVT efficacy, complications, in-hospital mortality, length-of-stay (LOS) and nutrition status at discharge.

RESULTS

A total of 156 patients were analyzed. During the latter period the primary endpoint MTL30 decreased from 60.8 to 39.0% (P = .006). EVT efficacy increased from 80 to 91% (P = .049). Further, the need for additional procedures for leakage management decreased from 49.9 to 29.9% (P = .013) and reoperations became less frequent (38.0% vs.15.6%; P = .001). The duration of leakage therapy and LOS were shortened from 25 to 14 days (P = .003) and 38 days to 25 days (P = .006), respectively. Morbidity (as determined by the comprehensive complication index) decreased from 54.6 to 46.5 (P = .034). More patients could be discharged on oral nutrition (70.9% vs. 84.4%, P = .043).

CONCLUSIONS

Our experience confirms the efficacy of EVT for the successful management of UGI leakage. Our quality improvement analysis demonstrates significant changes in EVT management resulting in accelerated recovery, fewer complications and improved functional outcome.

High risk and low prevalence diseases: Esophageal perforation

INTRODUCTION

Esophageal perforation is a rare but serious condition associated with a high rate of morbidity and mortality.

OBJECTIVE

This article highlights the pearls and pitfalls of esophageal perforation, including diagnosis, initial resuscitation, and management in the emergency department based on current evidence.

DISCUSSION

Esophageal perforation occurs with injury to the layers of the esophagus, resulting in mediastinal contamination and sepsis. While aspects of the history and physical examination may prompt consideration of the diagnosis, the lack of classic signs and symptoms cannot be used to rule out esophageal perforation. Chest radiograph often exhibits indirect findings suggestive of esophageal perforation, but these are rarely diagnostic. Advanced imaging is necessary to make the diagnosis, evaluate the severity of the injury, and guide appropriate management. Management focuses on hemodynamic stabilization with intravenous fluids and vasopressors if needed, gastric decompression, broad-spectrum antibiotics, and a thoughtful approach to airway management. Proton pump inhibitors and antifungals may be used as adjunctive therapies. Current available evidence for various treatment options (conservative, endoscopic, and surgical interventions) for esophageal perforation and resulting patient outcomes are limited. A multidisciplinary team approach with input from thoracic surgery, interventional radiology, gastroenterology, and critical care is recommended, with admission to the intensive care setting.

CONCLUSIONS

An understanding of esophageal perforation can assist emergency physicians in diagnosing and managing this deadly disease.

Treatment of esophageal perforation: A review of our experience at a tertiary referral hospital spanning the past 19 years

INTRODUCTION AND AIMS

Esophageal perforation is an uncommon event that is a medical/surgical emergency, with a 15-30% mortality rate. The aim of the present study was to communicate our experience in the management of esophageal perforation, evaluating the different strategies utilized, in an effort to establish measures to guide decision-making in selecting treatment.

MATERIALS AND METHODS

A retrospective descriptive study was conducted on patients diagnosed with esophageal perforation at our hospital center, within the time frame of 2000 and 2019.

RESULTS

Over the past 19 years, 15 patients were diagnosed with esophageal perforation. Surgical treatment was carried out in 80% of the cases. Primary closure, reinforced with plasty, was performed in 67% of the patients, of whom 62.5% had early diagnosis and a 100% survival rate. Diagnosis was late in 37.5% of the cases, with a 33.3% survival rate. Esophagectomy and gastric pull-up were performed on 25% of the patients, 66.6% of whom had early diagnosis and a 100% survival rate. In the 33.3% that had late diagnosis, the mortality rate was 100%. Esophagectomy, with cervical esophagostomy and feeding jejunostomy, was performed on one of the patients (8.3%) that had early diagnosis and a 100% survival rate.

CONCLUSIONS

The main survival predictor in esophageal perforation is the interval of time between the injury and its diagnosis, and in turn, the resulting treatment. Each patient with esophageal perforation should have individualized treatment to adequately manage the condition.

Conservative treatment of Boerhaave's syndrome in an octogenarian complicated with late distal esophageal stenosis and successfully treated by stent placement

An 83-year-old female patient presented to the Emergency Department with shortness of breath, difficulty swallowing and left-sided chest pain following a vomiting attempt. A rupture in the left lower third of the esophagus, with hydropneumothorax, pneumomediastinum, and subcutaneous emphysema was revealed by chest X-ray, thoracic computed tomography scan, and contrast esophagography. The patient was successfully treated conservatively with closed thoracostomy, intravenous fluids, parenteral nutrition, and broad-spectrum antibiotics coverage. Following the successful conservative treatment, the patient developed a distal esophageal stenosis which was treated with an intra-esophageal self-expanding stent.

Diagnostic challenge and surgical management of Boerhaave's syndrome: a case series

Background

Boerhaave’s syndrome is the spontaneous rupture of the esophagus, which requires early diagnosis and treatment. Symptoms may vary, and diagnosis can be challenging.

Case presentation

Case 1: A 54-year-old Chinese man presented to us with sudden-onset epigastric pain radiating to the back following hematemesis. Upper gastrointestinal endoscopy revealed a full-thickness rupture of the esophageal wall. Subsequent computed tomography showed frank pneumomediastinum and heterogeneous pleural effusion. Immediately, esophageal perforation repair operation and jejunostomy were performed. The postoperative period was uneventful, and he was discharged.

Case 2: A 62-year-old Chinese man was admitted to the emergency department with thoracic dull pain and chest distress. Chest computed tomography scan showed pneumomediastinum and large left-sided pleural effusion. Esophagus fistula was confirmed by contrast esophagography. Then, we performed thoracotomy to repair the esophageal tear as well as to debride and irrigate the left pleural space. His postoperative period was uneventful, with no leakage or stricture.

Case 3: The patient was a 69-year-old Chinese male presenting with severe retrosternal and upper abdominal pain following an episode of forceful vomiting. Thoracic computed tomography scan revealed a rupture in the left distal part of the esophagus, a pneumomediastinum, and left-sided pleural effusions. Conservative treatment failed to improve disease conditions. Open thoracic surgery was performed with debridement and drainage of the mediastinum and the pleural cavity, after which he made a slow but full recovery.

Conclusions

We highlight that early diagnosis and appropriate surgical treatment are essential for optimum outcome in patients with esophageal rupture. We emphasize the importance of critical care support, particularly in the early stages of management.

A Novel Hybrid Stent with Endoscopic Vacuum Therapy for Treating Leaks of the Upper Gastrointestinal Tract

Introduction

Self-expanding metal stents (SEMS) are an established option for treating leaks in the upper gastrointestinal tract, and endoscopic vacuum therapy (EVT) has become a promising alternative. A novel approach is the use of an esophageal hybrid SEMS (VACStent®), which can maintain esophageal passage during EVT. We present the first study demonstrating successful use of the VACStent® for treating leaks of the upper gastrointestinal tract.

Method

We performed a retrospective, single-center study of all patients who underwent endoscopic stenting with the VACStent® of leaks in the upper gastrointestinal tract.

Results

Indications for treatment with the VACStent® were: iatrogenic esophageal perforation (n = 1), spontaneous perforation (n = 2), esophageal fistula (n = 2), and anastomotic leak after upper gastrointestinal surgery (n = 5). Successful application of the VACStent® was achieved in all patients (n = 10; 100%) with a total of 15 interventions. VACStent® therapy was used as a first-line treatment in 5 patient (success rate 80%; 4 out 5 patients) and as a second-line treatment after failed previous endoscopic therapy in 5 patients (success rate 60%; 3 out of 5 patients). Overall, VACStent® treatment was successful in 70% of the patients (7 out of 10). No severe VACStent® treatment-related adverse events occurred.

Conclusion

The initial experience has been that the technical application of the VACStent® is safe and technically feasible. However, due to the small number of patients this study could not show the clear advantages of this novel hybrid stent. More studies are necessary to show significant advantages.

Spontaneous Esophageal Perforation in an Infant: A Rare Case

Spontaneous perforation of the esophagus is an emergency that requires early diagnosis and management. It may be fatal and delay in treatment can cause an increase in morbidity and mortality. Despite of being very rare in infants, we have to be watchful whenever we encounter signs and symptoms related to it. Only 7 cases of spontaneous esophageal perforation in infants have been report in the literature to the best of our knowledge. Here we are reporting a rare case of spontaneous esophageal rupture in an infant.

Secondary aortoesophageal fistula initially presented with empyema after thoracic aortic stent grafting: A case report

BACKGROUND

Massive upper gastrointestinal (GI) bleeding is usually urgent and severe, and is mostly caused by GI diseases. Aortoesophageal fistula (AEF) after thoracic aortic stent grafting is a rare cause of this condition, and has a poor prognosis with a high mortality rate. The clinical symptoms of AEF are usually nonspecific, and the diagnosis is often difficult, especially when upper GI bleeding is absent. Early identification, early diagnosis, and early treatment are very important for improving prognosis.

CASE SUMMARY

A 74-year-old man was admitted to the infectious disease department with > 10-d fever and 10-mo prior history of thoracic aortic stent grafting for thoracic aortic penetrating ulcers. Blood tests revealed elevated inflammatory indicators and anemia. Chest computed tomography (CT) showed postoperative changes of the aorta after endovascular stent graft implantation, pulmonary infection and pleural effusion. Pleural effusion tests showed empyema. After 1 wk of anti-infective treatment, temperature returned to normal and chest CT indicated improvement in pulmonary infection and reduction of pleural effusion. Esophageal endoscopy was performed because of epigastric discomfort, and showed a large ulcer with blood clot in the middle esophagus. However, on day 11, hematemesis and melena developed suddenly. Bleeding stopped temporarily after hemostatic treatment and bedside endoscopic hemostasis. Thoracic and abdominal aortic CT angiography confirmed AEF. Later that day, he suffered massive hemorrhage and hemorrhagic shock. Eventually, his family elected to discontinue treatment.

CONCLUSION

AEF should be strongly considered in patients with a history of aortic intervention who present with fever, especially with empyema.

Bovine xenograft pericardial patch use for definitive single stage repair of a large esophageal defect: a case report

Background

Large esophageal perforations are challenging and often treated with exclusion or resection. This case demonstrates the feasibility of definitive surgical repair of a large esophageal perforation using large bovine pericardial patch.

Case

A patient with missed Boerhaave Syndrome underwent transesophageal echocardiography causing worsening perforation and sepsis. At thoracotomy and faced with a large esophageal defect, a large Bovine pericardial patch was used for repair with omentopexy. The patient recovered promptly and at 8 months was asymptomatic with satisfactory studies.

Conclusion

Xenograft pericardium is available and widely used for vascular reconstructions. It’s use for primary repair of large esophageal perforations should be considered.

Prognostic factors of esophageal perforation and rupture leading to mortality: a retrospective study

Background

Esophageal perforation and rupture (EPR) is a serious, potentially life-threatening condition. However, no treatment methods have been established, and data concerning factors affecting mortality are limited. This report presents the prognostic factors of mortality in EPR based on experience in the management of such patients.

Methods

For this retrospective analysis, 79 patients diagnosed as having EPR between 2006 and 2016 and managed at Gyeongsang National University Hospital were examined. The management method was determined in accordance with the location and size of the EPR, laboratory findings, and radiological findings. Thirty-nine patients were treated with surgery; and 40, with nonsurgical management.

Results

The most common cause of EPR was foreign body (fish bone or meat bone), followed by vomiting, iatrogenic causes, and trauma. Thirty-nine patients underwent primary repair of EPR, of whom 4 patients died. Forty patients underwent nonsurgical management, of whom 3 patients died. The remaining patients were discharged. Mortality correlated with the size of the EPR (> 25 mm) and the segmented neutrophil count percentage (> 86.5%) in the white blood cell test and differential.

Conclusions

The mortality risk was increased when the EPR size and the segmented neutrophil count percentage in the white blood cell test and differential was high. Delayed diagnosis, which was considered an important predictive factor in previous investigations, was not statistically significant in this study.

Trial registration: Not applicable.
