Rigid esophagoscopy combined with angle endoscopy for treatment of superior mediastinal foreign bodies penetrating into the esophagus caused by neck trauma: A case report

BACKGROUND

Herein, we report a case in whom two foreign bodies entered the upper mediastinal cavity from the cervical root and subsequently the esophagus. Surgery is the preferred treatment method, and operational procedures depend on the size and location of the foreign body relative to the mediastinal vessels. Rigid esophagoscopy combined with angle endoscopic surgery was selected to avoid surgical trauma and complications.

CASE SUMMARY

A 63-year-old male patient with a 6-mo old history of neck trauma presented with a black-brown foreign body in the lateral wall of the esophagus. Neck and chest computed tomography (CT) revealed that two superior mediastinal foreign bodies penetrated the esophagus diagonally. We removed two foreign bodies through an esophagoscope. Owing to the rigid working channel of esophagoscope and good exposure of endoscope, the risk of injury to the adjacent vital tissues was minimized. Postoperative comprehensive therapies, including antibiotic administration and nutritional support, resulted in a prompt postoperative recovery. Postoperative CT confirmed the absence of a residual foreign body and neck and chest infections. In addition, upper gastrointestinal angiography and gastroscopy revealed the absence of an evident esophageal perforation. The patient received an oral diet and did not experience any complication at the time of discharge from the hospital.

CONCLUSION

Rigid esophagoscopy combined with angle endoscopy is an effective, minimally invasive treatment for penetrating neck injuries.

Esophageal perforation after transesophageal echocardiography: A case report

•

Esophageal perforation after ambulatory Transesophageal Echocardiography is rare.

•

High suspicion in crucial to establish a diagnosis.

•

If discovered early, treatment of esophageal perforation could have good outcome.

•

Endoscopy plays an important role in the diagnosis and treatment.

•

The endoscopic approach is a safe and feasible option to avoid major surgery.

Introduction

Esophageal perforation is a rare and severe complication following transesophageal echocardiography (TEE) that carries high morbidity and mortality rates. Management of these perforations usually requires complex open surgeries. We present the case of an esophageal perforation following TEE treated with a combined approach of upper endoscopy and left cervicotomy.

Presentation of case

An 80 y/o male patient underwent a diagnostic TEE for mitral regurgitation. After discharge patient consulted back on the same day to the Emergency Department and a perforation of the cervical esophagus was diagnosed associated to an air-fluid collection in the mediastinum. The patient was treated with endoscopic closure of the perforation and left cervicotomy for mediastinal drainage. Patient was discharged home on POD 31 after full recovery. A written consent was previously obtained, and Institutional Review Board approval was not needed.

Discussion

Although not frequently seen, complications following TEE can be devastating if not diagnosed and treated early. Endoscopic closure of an esophageal perforation is a safe and feasible option with the already known advantages of a minimally invasive approach. Surgeons should have high suspicion if a patient present with characteristic symptoms after an uneventful procedure.

Conclusion

Esophageal perforation is a very rare complication of TEE. High suspicion is mandatory to reach prompt diagnosis and install effective treatment. Primary closure of the perforation is the treatment of choice, and the endoscopic approach is a safe and feasible option in high volume centers.

Self-expanding esophageal stents for the management of benign refractory esophageal strictures in children: A systematic review and review of outcomes at a single center

BACKGROUND

This study aimed to evaluate our outcomes and complication rate following placement of self-expanding esophageal stents in children for the management of refractory esophageal strictures and comparing these to the existing literature.

METHODS

Outcomes following placement of stents in consecutive patients under 18 years at a single center from 2003 to 2018 were reviewed. A PRISMA-guided systematic review was conducted identifying studies with 5 or more children evaluating self-expanding stents published from 1975 to 2018. Endpoints for both the retrospective and systematic reviews were the requirement for further intervention and stent-associated complications.

RESULTS

25 patients received 65 stents. There were 12 caustic injury-related strictures (48%), 9 anastomotic strictures (36%), and 4 esophagitis-related strictures (16%). Four patients were lost to follow-up. 19/21 patients (90%) required further intervention, and 8/21 (38%) had esophageal replacement. Nine studies, all case series, were included in the systematic review. 97 patients received 160 stents for esophageal strictures and/or perforation. 36 out of 69 patients (52%) with strictures required no further treatment post-stenting, and 22/29 (76%) of esophageal perforations closed with stenting.

CONCLUSIONS

Esophageal stents may have a role as a bridge to definitive surgery and for the management of esophageal leaks, but complete stricture resolution post-stenting is unlikely.

TYPE OF STUDY

Treatment Study (Case Series with no Comparison Group) LEVEL OF EVIDENCE: Level IV.

Transcatheter embolization of the esophagomediastinal fistula with N-butyl cyanoacrylate glue: A case report

•

Acute mediastinitis with esophageal perforation is a fatal disease.

•

Esophagomediastinal fistula due to esophageal perforation is difficult to curable treatment.

•

Successful embolization of the esophagomediastinal fistula with N-butyl cyanoacrylate.

Introduction

Acute mediastinitis with esophageal perforation is a very fatal condition and must be treated promptly. Esophagomediastinal fistula is a rare complication of acute mediastinitis with esophageal perforation. There are many treatment options such as surgery or endoscopic treatment, but it is most important to start treatment immediately.

Presentation of case

A 69-year-old female presented with chest pain and fever. Contrast enhanced chest computed tomography was compatible with acute mediastinitis and esophageal perforation. Esophagography revealed esophagomediastinal fistula in the upper esophagus. Endoscopic clipping with fibrin was failed and endoscopic vacuum therapy (EVT) was not effective for esophagomediastinal fistula. We performed the successful transcatheter embolization of the esophagomediastinal fistula with N-butyl cyanoacrylate (NBCA) glue.

Discussion

There are many considerations in the treatment of acute mediastinitis with esophageal perforation, but surgery is the mainstay of treatment. Recently non operative management is appropriate in certain well-defined situations. Like our case patients, non-operative management may be considered if the diagnosis is delayed and the surgical treatment period is missed. Currently, endoscopic treatment such as covered stenting, clipping and application of fibrin glue are useful and a less invasive rather than surgical treatment. However, if endoscopic or surgical procedure are not possible, we considered transcatheter NBCA glue embolization.

Conclusion

Transcatheter embolization with NBCA glue was proven to its effectiveness as an alternative therapeutic option in the treatment of esophagomediastinal fistula which endoscopic or surgical treatment are impossible or fails.

[Analysis in diagnosis and treatment of 29 cases of cervical esophageal perforation]

Objective: To analyze and summarize the method and effect of cervical esophagus perforation. Methods: A total of 29 cervical esophageal perforation patients caused by foreign body were retrospectively analyzed from January 2012 to June 2018 in Department of Otorhinolaryngology Head and Neck Surgery, the First Affiliated Hospital of Nanchang University. Results: Among the 29 cervical esophageal perforation patients, 28 patients were extracted by lateral neck incision, 1 patient with carotid artery hemorrhea was rescued by repairing the fistula between carotid artery and esophage. All patients recovered and successfully discharged. There were no severe complications among all patients. Conclusions: The cervical CT scan is important for diagnosing a cervical esophageal perforation. Enhancement CT scan is necessay for a patient with haematemesis. Lateral neck incision would be first choice for patients with big foreign bodies. Inflammatory reaction and finger palpation are helpful for locating foreign bodies.

Successful percutaneous computed tomography guided drainage of mediastinal abscess in esophageal perforation

Esophageal perforation with subsequent development of a mediastinal abscess is a well-known clinical entity. Etiologies including idiopathic and iatrogenic with invasive procedures have been reported in medical literatures. This condition is seriously associated with high co-morbidity and in some cases especially if intervention has not been applied associated with high mortality. For long time, open surgical intervention was the only available treatment modality for esophageal perforation with subsequent development of a mediastinal abscess. However, recently there are some other less invasive modalities that have been used with comparable if not preferable success including; self-expandable metallic or plastic stents and imaging guided percutaneous drainage of the mediastinal abscess combined with stenting. We report a patient who presented with esophageal perforation complicated with a mediastinal abscess that was treated successfully with an imaging guided percutaneous drainage of the mediastinal abscess. This case is to emphasize on the fact that endoscopic stent placement is safe and effective for esophageal perforations. Percutaneous CT-guided drainage of associated mediastinal abscesses is an uncommon procedure, but the results suggest that it is associated with high technical and clinical success rates. There should be increased involvement of interventional radiology in the management of those cases.

Esophageal Perforation after Anterior Cervical Spine Surgery

Study Design

Retrospective case analyses.

Purpose

To investigate the causes, diagnosis, and management of esophageal perforation, depending on the time of diagnosis.

Overview of Literature

To date, few studies have addressed these issues.

Methods

A total of seven patients were included in this study. The patients were classified into three groups based on esophageal perforation diagnosis time: intraoperative (diagnosed during surgery), perioperative (diagnosed within 30 days postoperatively), and delayed (diagnosed >30 days postoperatively) groups.

Results

In the intraoperative group (N=2), infectious spondylitis was the main cause of esophageal perforation. Anterior plate and screw removal, followed by posterior instrumentation, was performed. The injured esophagus was managed by omentum flap repair in one patient and primary repair in one patient. In the perioperative group (N=2), revision surgery for infection and metal failure were the main causes of esophageal perforation. In both cases, food residue was drained on the third postoperative day. The injured esophagus was managed conservatively. In the delayed group (N=3), chronic irritation caused by metal failure was the main cause of esophageal perforation. In all patients, there was no associated infection. The anterior instrumentation was removed, and the two patients were treated by primary repair, and one patient was treated using sternocleidomastoid muscle flap. One patient in intraoperative group died of sepsis.

Conclusions

The main cause of intraoperative esophageal perforation was esophageal adhesions because of infectious spondylitis. However, perioperative and delayed esophageal perforations were caused by chronic irritation because of metal failure. Anterior plate and screw removal was necessary, and posterior instrumentation and fusion may be considered, depending on the fusion status.

Iatrogenic esophageal perforation that could be treated indirectly by cervical esophagostomy and laparoscopic surgery

•

It is very rare case that each esophageal stump become connected and patent spontaneously.

•

Two-stage surgery is useful for esophageal perforation if radical operation is difficult.

•

Esophageal perforation can be resolved without direct closure if appropriate drainage is performed.

Introduction

Successful nonoperative management has been reported for esophageal perforation; however, some cases require surgery.

Case presentation

We presented the case of an 85-year-old woman with iatrogenic thoracic esophageal perforation in whom primary repair or resection of the perforated esophagus was difficult because she was elderly and had severe aortic valve stenosis. Therefore, we selected a two-stage surgery; laparoscopic gastrostomy, jejunostomy, posterior mediastinal drainage, and cervical esophagostomy were performed. We planned reconstruction after the perforation was closed, but endoscopic examination revealed spontaneous patency of each esophageal stump. Endoscopic balloon dilation was necessary because of esophageal stenosis; however, anastomotic surgery was unnecessary.

Conclusion

This case report suggests that esophageal perforation is resolved without direct closure if appropriate drainage is performed.

Esophageal emergencies: WSES guidelines

The esophagus traverses three body compartments (neck, thorax, and abdomen) and is surrounded at each level by vital organs. Injuries to the esophagus may be classified as foreign body ingestion, caustic ingestion, esophageal perforation, and esophageal trauma. These lesions can be life-threatening either by digestive contamination of surrounding structures in case of esophageal wall breach or concomitant damage of surrounding organs. Early diagnosis and timely therapeutic intervention are the keys of successful management.

Minimally invasive surgical management of spontaneous esophageal perforation (Boerhaave's syndrome)

BACKGROUND

Spontaneous esophageal perforation (Boerhaave's syndrome) is a highly morbid condition traditionally associated with poor outcomes. The Pittsburgh perforation severity score (PSS) accurately predicts risk of morbidity, length of stay (LOS) and mortality. Operative management is indicated among patients with medium (3-5) or high (> 5) PSS; however, the role of minimally invasive surgery remains uncertain.

METHODS

Consecutive patients presenting with Boerhaave's syndrome with intermediate or high PSS managed via a thoracoscopic and laparoscopic approach from 2012 to 2018 were reviewed. Demographics, clinical presentation, management, and outcomes were analyzed.

RESULTS

Ten patients (80% male) with a mean age of 61.3 years (range 37-81) were included. Two patients had intermediate and eight had high PSS (7.9 ± 2.8, range 4-12). The mean time from onset of symptoms to diagnosis was 27 ± 12 h and APACHE II score was 13.6 ± 4.9. Thoracoscopic debridement and primary repair was performed in eight cases, with two perforations repaired primarily over a T-tube. Laparoscopic feeding jejunostomy was performed in all patients. Critical care LOS was 8.7 ± 6.8 days (range 3-26), while inpatient LOS was 23.1 ± 12.5 days (range 14-46). Mean comprehensive complications index was 42.1 ± 26.2, with grade IIIa and IV morbidity in 60% and 10%, respectively. One patient developed dehiscence at the primary repair, which was managed non-operatively. In-hospital and 90-day mortality was 10%.

CONCLUSION

Minimally invasive surgical management of spontaneous esophageal perforation with medium to high perforation severity scores is feasible and safe, with outcomes which compare favorably to the published literature.

Acute esophageal necrosis with esophagus perforation treated by thoracoscopic subtotal esophagectomy and reconstructive surgery on a secondary esophageal stricture: a case report

BACKGROUND

Acute esophageal necrosis is defined as necrosis of the esophageal mucosa causing diffuse black pigmentation of the esophagus, the so-called black esophagus from its endoscopic findings. The prevalence is only 0.001~0.2%, while its mortality rate is up to 32%. However, most of the cases are fatal by comorbidities.

CASE PRESENTATION

A 67-year-old female with diabetes mellitus was transported to the emergency room with hematemesis and disordered consciousness. She had suffered from nausea and epigastralgia for 2 days. The patient's general status was shock evidenced by vital signs, and she did not respond to rehydration. After intubation, emergency endoscopic examination revealed black pigmentation of the esophageal mucosa, and the condition was diagnosed as acute esophageal necrosis. Antibiotics and plasmapheresis had been started, and the patient gradually stabilized. One week after the admission, esophagus perforation was suspected from the significant increase of the right pleural effusion and free air at the esophagus wall and the mediastinum on CT scan. Emergency thoracoscopy revealed an edematous esophagus which was colored black. Esophagectomy with esophagostomy and enterostomy was performed. On resected specimen, mucosal necrosis was found only on the squamous epithelium, with three perforating areas in the middle to lower thoracic esophagus. No signs of inflammation or ischemia were found on the gastric mucosa of the esophagogastric junction. After the operation, the patient recovered generally well, except for the severe stenosis of the cervical esophagus. Cervical esophagectomy, tracheotomy, and anterior thoracic route reconstruction with free jejunum interposition and gastric tube were performed 9 months after the first surgery. No postoperative complications occurred; on the 37th day after the operation, the patient was eating well and was transferred to continue swallowing rehabilitation.

CONCLUSION

It is important to detect the esophagus perforation and mediastinitis early and thereby not to miss the chance of surgical intervention to save the patient's life. Surgery should be minimized, and reconstruction should be considered next. If the cervical esophagus is also affected, reconstruction surgery should be performed by removing cervical esophagus and anastomosing it to the hypopharynx using a gastric tube and free jejunum interposition as needed.

Endoscopic closure of gastrointestinal perforations and fistulas using the Ovesco Over-The-Scope Clip system at a tertiary care hospital center

INTRODUCTION AND AIM

Enteric perforations and fistulas are difficult to manage due to comorbidities, poor nutritional status, and anatomic challenges related to multiple interventions in those patients. The use of endoscopic methods as a nonsurgical approach is increasing. The aim of the present study was to describe the clinical experience with the use of the Ovesco Over-The-Scope Clip system in the closure of perforations, fistulas, and other indications in the digestive tract at a tertiary care hospital center.

MATERIALS AND METHODS

A case series was carried out on patients that underwent lesion closure with the Ovesco clip, within the time frame of January 2015 to December 2017.

RESULTS

The Ovesco clip was used for closure in 14 patients ranging in age from 21-90 years, with different indications: iatrogenic perforations; anastomotic leaks and fistulas; tracheoesophageal fistulas; and esophagogastric perforation. Technical success was achieved in 100% of the patients and clinical success in 78.57%. No complications were reported.

CONCLUSIONS

The Ovesco Over-The-Scope Clip system is a safe and effective method for managing gastrointestinal acute perforations and fistulas.

Thoracic Complications of Bariatric Surgeries: Overlooked Entities

INTRODUCTION

Bariatric surgeries are increasingly performed to treat obesity worldwide. The currently available literature on these surgeries mainly focuses on their abdominal complications, giving less attention to their thoracic ones. Hence, the present work aimed to highlight the thoracic complications associated with bariatric surgeries.

METHODS

A retrospective descriptive study was performed and involved the review of the medical charts of 390 patients who underwent different bariatric surgeries between January 2014 and January 2017 in our hospital or who were referred to us from other centers after their specific operations. The data of patients who developed thoracic complications and who required further intervention were identified and categorized by the modality of diagnosis, outcome, duration of hospital and ICU stays, and management. Patients with a history of a preexisting pulmonary disease were excluded.

RESULTS

Twenty-six patients were observed to have thoracic complications secondary to their bariatric surgeries. Twenty-two patients (84.6%) received post-laparoscopic sleeve gastrectomy (LASG). Nine patients (34.6%) required ICU stays. Twenty patients (76.9) had incidences of pleural effusion in the postoperative period. The mean duration of hospital and ICU stays were 4.4 ± 11.67 days and 15 ± 19.36 days, respectively. Other reported thoracic complications included esophageal perforations, thoracic empyema, septic pericardial effusion, and pancreaticopleural fistula.

CONCLUSION

Bariatric surgeries are safe procedures in selected patients. There is a significant amount of literature describing abdominal, nutritional, neurological, and even ophthalmic complications after bariatric surgeries. Being that they are relatively rare, thoracic complications are underreported in the literature. The management of thoracic complications after bariatric surgery requires awareness and a high index of suspicion to prevent further morbidities and mortalities.

Surgical management and prognostic factors in esophageal perforation caused by foreign body

OBJECTIVES

Esophageal perforation is associated with multiple serious complications and high mortality. Herein, we identify some predictors for postoperative outcomes, compare the outcomes of various surgical approaches, and summarize our experience with esophageal perforation over the past 13 years.

METHODS

We retrospectively analyzed 38 patients diagnosed with esophageal perforation caused by foreign body between November 2004 and May 2018. Univariate analysis and multivariate logistic regression analysis were performed to identify potential risk factors related to prognosis. Effects of different surgery were compared based on postoperative outcomes.

RESULTS

Of the 38 patients, the number of females was equal to males with a mean age of 55.6 ± 14.9 (range 23-93) years; 22 had thoracic perforations and 16 had cervical perforations. The overall mortality rate was 5.3%. Univariate analysis revealed that sex (p = 0.049), type of foreign body (p = 0.042), abscess (p = 0.049), and site of perforation (p = 0.031) were associated with prognosis. The interval between perforation and surgery did not significantly influence prognosis (p = 0.929). No significant difference was found in postoperative outcomes among various surgeries.

CONCLUSIONS

The interval between perforation and treatment was not as important as previously reported. Surgical management should be performed early when feasible, even if the interval between perforation and surgery is 24 h or longer.

A case of esophageal perforation after intraoperative transesophageal echocardiography in a patient with a giant left atrium: unexpectedly large distortion of the esophagus revealed on retrospectively constructed three-dimensional imaging

Background

Esophageal perforation is a rare but serious complication of transesophageal echocardiography (TEE). An enlarged left atrium (LA), which is commonly associated with mitral stenosis (MS), is an under-recognized risk factor for esophageal perforation after intraoperative TEE.

Case presentation

We describe a case of TEE-induced esophageal perforation after cardiac surgery in a 79-year-old woman with a giant LA due to MS. Esophageal perforation was detected on postoperative day 6. After surgical repair, the patient gradually recovered with prolonged conservative treatment. Retrospectively constructed three-dimensional chest computed tomography images revealed an unusually distorted esophagus that was possibly vulnerable to injury.

Conclusion

A giant LA can markedly distort the esophagus. It should be recognized as a risk factor for TEE-induced esophageal perforation.

Esophageal perforation secondary to malignant gastric outlet obstruction: a case report

Background

Esophageal perforation is a rare presenting sign of gastric cancer. To date, only nine case reports of this phenomenon have been previously published.

Case presentation

Esophageal perforation was diagnosed radiographically during workup for acute chest pain in a 67-year-old man. Emergent endoscopy confirmed esophageal perforation and biopsied a pre-pyloric mass confirmed to be adenocarcinoma. The perforation was managed with endoscopically placed transluminal pleural and mediastinal drains and esophageal stenting. The gastric outlet obstruction was temporized with a transpyloric stent. After the patient recovered from sepsis, distal gastrectomy was performed and he made a full recovery.

Conclusions

Rarely, pre-pyloric gastric cancer can present with Boerhaave syndrome, spontaneous esophageal perforation associated with forceful vomiting. We present the tenth report in the literature of this phenomenon and the first to be initially treated with endoscopic stenting and transluminal thoracoscopic drainage. When endoscopic management is used to treat patients with Boerhaave syndrome, it may be beneficial to examine the entire stomach to evaluate for malignant etiology.

Endoluminal Therapies for Esophageal Perforations and Leaks

Esophageal perforation has historically been a devastating condition resulting in high morbidity and mortality. The use of endoluminal therapies to treat esophageal leaks and perforations has grown exponentially over the last decade and offers many advantages over traditional surgical intervention in the appropriate circumstances. New interventional endoscopic techniques, including endoscopic clips, covered metal stents, and endoluminal vacuum therapy, have been developed over the last several years to manage esophageal perforation in an attempt to decrease the related morbidity and mortality.

Perforation of the esophagus due to thermal injury after laparoscopic radiofrequency ablation for hepatocellular carcinoma: a case for caution

Background

Several reported complications associated with radiofrequency ablation for liver tumors are due to thermal damage of neighboring organs. We herein report a first case of esophageal perforation due to thermal injury of laparoscopic radiofrequency ablation (RFA).

Case presentation

A 75-year-old woman was treated repeatedly with RFA (percutaneous and laparoscopic) and transcatheter arterial chemoembolization for hepatocellular carcinoma. One week after laparoscopic RFA for recurrent HCC located in segment 2 of the liver, dysphagia and thoracic pain occurred. Upper gastrointestinal endoscopy revealed a perforated esophageal ulcer at the esophago-gastric junction. Inflammation was localized because of severe intra-abdominal adhesion due to repeat surgery, so we decided to treat the patient conservatively. The perforation of the esophagus gradually scarred, and exacerbation did not occur after restarting oral intake.

Conclusions

When patients with a history of abdominal surgery or intra-abdominal inflammation undergo thermal ablation therapy, caution is required, as there is a possibility of thermal injury of unexpected organs.

Tension hydropneumothorax as the initial presentation of Boerhaave syndrome

Boerhaave syndrome, a rare yet frequently fatal diagnosis, is characterized by the spontaneous transmural rupture of the esophagus. The classic presentation of Boerhaave syndrome is characterized by Mackler's triad, consisting of chest pain, vomiting, and subcutaneous emphysema. However, Boerhaave syndrome rarely presents with all the features of Mackler's triad; instead, the common presentation of Boerhaave syndrome includes chest or epigastric pain, severe retching and vomiting, dyspnea, and shock. These symptoms are typically misdiagnosed as cardiogenic in origin. Due to its atypical presentation, rarity, and mimicry of emergent conditions, diagnosis of Boerhaave syndrome is often delayed, resulting in a high mortality rate at the time of diagnosis and with a subsequent exponential increase in mortality if treatment is delayed by greater than 48 hours. Here, we report two atypical presentations of Boerhaave syndrome presenting as tension hydropneumothorax and review ten previously reported cases of Boerhaave syndrome presenting as tension hydropneumothorax. This review serves to raise clinician awareness about the expansive and elusive ways by which esophageal perforation may present, and thereby facilitate timely and potentially life-saving diagnosis.

Regulating migration of esophageal stents - management using a Sengstaken-Blakemore tube: A case report and review of literature

Stent migration, which causes issues in stent therapy for esophageal perforations, can counteract the therapeutic effects and lead to complications. Therefore, techniques to regulate stent migration are important and lead to effective stent therapy. Here, in these cases, we placed a removable fully covered self-expandable metallic stent (FSEMS) in a 52-year-old man with suture failure after surgery to treat Boerhaave syndrome, and in a 53-year-old man with a perforation in the lower esophagus due to acute esophageal necrosis. At the same time, we nasally inserted a Sengstaken-Blakemore tube (SBT), passing it through the stent lumen. By inflating a gastric balloon, the lower end of the stent was supported. When the stent migration was confirmed, the gastric balloon was lifted slightly toward the oral side to correct the stent migration. In this manner, the therapy was completed for these two patients. Using a FSEMS and SBT is a therapeutic method for correcting stent migration and regulating the complete migration of the stent into the stomach without the patient undergoing endoscopic rearrangement of the stent. It was effective for positioning a stent crossing the esophagogastric junction.

Time to perforation for button batteries lodged in the esophagus

INTRODUCTION

New strategies recently proposed to mitigate injury caused by lithium coin cell batteries lodged in the esophagus include prehospital administration of honey to coat the battery and prevent local hydroxide generation and in-hospital administration of sucralfate suspension (or honey). This study was undertaken to define the safe interval for administering coating agents by identifying the timing of onset of esophageal perforations.

METHODS

A retrospective study of 290 fatal or severe battery ingestions with esophageal lodgment was undertaken to identify cases with esophageal perforations.

RESULTS

Esophageal perforations were identified in 189 cases (53 fatal, 136 severe; 95.2% in children ≤4 years). Implicated batteries were predominantly lithium (91.0%) and 92.0% were ≥20 mm diameter. Only 2% of perforations occurred in <24 h following ingestion, including 3 severe cases with perforations evident at 11-17 h, 12 h, and 18 h. Another 7.4% of perforations (11 cases) became evident 24 to 47 h post ingestion and 10.1% of perforations (15 cases) became evident 48 to 71 h post ingestion. By 3 days post ingestion, 26.8% of perforations were evident, 36.9% by 4 days, 46.3% by 5 days, and 66.4% by 9 days.

CONCLUSION

Esophageal perforation is unlikely in the 12 h after battery ingestion, therefore the administration of honey or sucralfate carries a low risk of extravasation from the esophagus. This first 12 h includes the period of peak electrolysis activity and battery damage, thus the risk of honey or sucralfate is low while the benefit is likely high.

Diabetes is an independent risk factor for delayed perforation after foreign bodies impacted in esophagus in adults

Background

Perforation is the most serious complication of esophageal foreign bodies. Studies examining the association between diabetes and esophageal foreign body-induced perforation are largely non-existent.

Objectives

The purpose of this study was to identify the risk factors for esophageal foreign body-induced perforation.

Methods

A retrospective chart review of patients with esophageal foreign bodies between January 2012-January 2017 was performed at the Chinese People's Liberation Army General Hospital. The patients were divided into two groups: those complicated with perforation and those without perforation. Date on patient demographics, symptoms, foreign bodies, and diabetes were collected and analyzed. Study-specific odds ratio and 95% confidence intervals (CI) were estimated using multivariable logistic regression models.

Results

Of 294 patients with esophageal foreign bodies (41.84% male, mean age, 56.73 years), 33 (11.22%) complicated by perforation. Diabetes (odds ratio = 6.00; 95% confidence interval = 1.72-20.23), duration (>24 h) of foreign bodies retention (odds ratio = 4.25; 95% confidence interval = 1.71-10.86), and preoperative fever (odds ratio = 8.19; 95% confidence interval = 3.17-21.74) were strongly associated with an increased risk of perforation, whereas the sensation of a foreign body (odds ratio = 0.32; 95% confidence interval = 0.09-0.92) was a protective factor of perforation. Glucose level was not observed to have an association among patients with or without perforation.

Conclusions

Diabetes and duration of foreign body retention increase risk for esophageal foreign bodies complicated by perforation, and cases with elevated armpit temperature may represented a more likely perforation compared with those without fever.

Case report of a conservative management of cervical esophageal perforation with acrylic glue injection

BACKGROUND

perforation of the upper aerodigestive tract is a potentially life-threatening condition. The appropriate treatment of cervical esophageal perforation is still controversial.

CASE PRESENTATION

we report a case of cervical esophageal perforation that was effectively treated by a conservative management with acrylic glue injection.

DISCUSSION

the management of cervical esophageal perforations has been controversial and little studied. Various treatment options, including surgical and nonsurgical management have been advocated, and no gold standard surgical treatment has yet been established. Some authors have recommended immediate surgical intervention, especially in penetrating trauma, conversely, several studies support conservative management.

CONCLUSIONS

we consider that the application of acrylic glue can be considered a promising, minimally invasive therapeutic option in the management of cervical esophageal perforation. However, the sufficient accumulation of similarly treated cases is necessary in order to confirm the efficacy and safety of this treatment modality.

Esophageal perforation in children: etiology and management, with special reference to endoscopic esophageal perforation

Perforation of the esophagus is an uncommon problem with significant morbidity and mortality. In children undergoing endoscopy, the risk of perforation is higher when interventional endoscopy is performed. The clinical features depend upon the site of esophageal perforation. Opinions vary regarding the optimal treatment protocol, and the role of conservative management in this context is not well established. Esophageal perforation that occurs as a consequence of endoscopy in children requires careful evaluation and management, as outlined in this article.

Boerhaave syndrome due to hypopharyngeal stenosis associated with chemoradiotherapy for hypopharyngeal cancer: a case report

Background

Spontaneous esophageal rupture, also known as Boerhaave syndrome, is a very serious life-threatening benign disease of the gastrointestinal tract. It is typically caused by vomiting after heavy eating and drinking. However, in our patient, because of a combination of hypopharyngeal cancer with stenosis and chemoradiotherapy (CRT), which caused chemotherapy-induced vomiting, radiotherapy-induced edema, relaxation failure, and delayed reflexes; resistance to the release of increased pressure due to vomiting was exacerbated, thus leading to Boerhaave syndrome. To the best of our knowledge, this is the first report of a patient with esophageal rupture occurring during CRT for hypopharyngeal cancer with stenosis.

Case presentation

A 66-year-old man with a sore throat was referred to our hospital. He was found to have stage IVA hypopharyngeal cancer, cT2N2bM0, and underwent radical concurrent CRT consisting of weekly cisplatin (30 mg/m²) and radiation (70 Gy/35fr), for larynx preservation. On day 27 of treatment, he vomited, which was followed by severe left chest pain radiating to the back and the upper abdomen. Enhanced computed tomography (CT) revealed extensive mediastinal emphysema and a small amount of left pleural effusion. Esophagography revealed extravasation into the left thoracic cavity, and the patient was diagnosed with an intrathoracic rupture type of Boerhaave syndrome. He underwent emergency left thoracotomy 21 h after the onset. The ruptured esophageal wall was primarily repaired by closure with two-layer suturing and covered by a pedicled omentum. A jejunostomy tube was placed for postoperative enteral nutrition. On postoperative day (POD) 16, the patient was transferred to head and neck surgery to finish CRT and was discharged on POD 56. He has survived without relapse for 11 months after surgery.

Conclusion

Patients with head and neck cancer are at risk for developing Boerhaave syndrome during CRT. In addition, since such patients often are in poor overall condition because of immunosuppression and protracted wound healing, Boerhaave syndrome can rapidly lead to severe life-threatening infections such as empyema and mediastinitis. Therefore, awareness of this condition is important so that appropriate treatment can rapidly be implemented to increase the likelihood of a good outcome.
