Also, I have no financial relationships to disclose and do not intend to discuss non FDA approved uses of drugs or medical equipment. Now the rest of the story • Admitted to CCHMC 5/25/09 to 5/29/09 – CT with contrast: pneumomediastinum – ENT, GI, PULM, RHEUM – Stopped antibiotics/discharged home • Outpatient procedure 6/3/09 – Nl laryngoscopy and bronchoscopy – EGD: Esophageal and gastric ulcers with air bubbling out esophageal lesion with purulent discharge – BAL showed acute inflammatory exudate Now the rest of the story #2 • Further Diagnosis – Esophagram: • esophageal ulcer right anterolateral aspect 3 cm above LES • Communicated with right infrahilar retrocardiac region • Treatment – NJ feeds, IV PPI, NPO for 14 days, unasyn 14 days – Repeat esophagram 6/25/09, no leak – Advanced to regular diet Follow Up • Chest CT 6/26/09 • EGD/Bronch 7/28/09 – Healing of previous esophageal ulcer – Gastric ulcer, mild gastritis – Negative bronchoalveolar lavage • EGD 11/24/09 – Gastric ulcer, healed esophageal ulcer – Mild distal esophagitis and gastritis • EGD 6/28/10 Objectives • Understand the high morbidity and mortality for esophageal perforation in children and the need for a high index of suspicion to ensure a timely diagnosis • Illustrate the diagnostic approach for the evaluation of esophageal perforation in children Outline • Esophageal Peroration – Etiology of esophageal perforation – Manifestations/Presentation – Diagnosis – Management • Chest Pain – Non-cardiac causes – Pericarditis – Mediastinitis Quick Look at the Objectives • Morbidity and Mortality – Morbidity: roughly 1/3 • Prolonged mechanical ventilation or persistent leak – Mortality: • Wide range: 4 to 44% • Usually from sepsis or multi-organ failure • Increased with delay in dx and tx • Diagnostic Approach – Plain radiographs: may be normal – Contrast esophagography: study of choice with controversary over ideal agent Etiology • Most cases are traumatic or iatrogenic • Spontaneous – Boerhaave syndrome – Triad of emesis, chest pain, and subcutaneous emphysema • Case reports • Review of experience Historical Background • 1723: Herman Boerhaave described barogenic esophageal rupture • 1947: first surgical repair of esophageal perforation • 1952: first esophagectomy after perforation and infant with spontaneous perforation related to esophageal web • 1961: first report in newborn after respiratory suctioning • 1960’s to 1970’s: improved M&M • 1980’s +: change in etiology Etiology: Adult • Adult review published in 2004 (N=559) • Instrumentation (59%) • Spontaneous (15%) • Foreign Body (12%) • Trauma (9%) • Operative Injury (2%) • Other (2%) Ann Thorac Surg 2004;77:1475-1483 Risk With Endoscopy • • • • Flexible: 0.03% Rigid: 0.11% Dilation: 0.09 to 5% Sclerotherapy:1 to 5% Etiology: Children • Children’s Mercy Hospital, Kansas City – 1995 to 2010, retrospective chart review • Etiology (n=8) – Stricture dilation 4 – Foreign Body 2 – NG tube and stricture resection 1 each • 75% of esophageal perforations are iatrogenic • All were managed conservatively Journal of Surgical Research: 164, 13-7, 2010 Etiology: Children • James Whitcomb Riley Hospital, Indiana – 1975 to 1995, retrospective review • Etiology (n=25) – Iatrogenic 17 • Dilation (8), operation (5), NG tube (2), endoscopy(2) – Traumatic 3 • Gun shot wound (2), blunt (1) – Foreign Body – Unknown • No cases of spontaneous Arch Surgery;131,611-618,1996 3 2 Etiology: Children • James Whitcomb Riley Hospital, Indiana – 1975 to 1995, retrospective review • Etiology (n=25) – Iatrogenic 17 • Dilation (8), operation (5), NG tube (2), endoscopy(2) – Traumatic 3 • Gun shot wound (2), blunt (1) – Foreign Body – Unknown 3 2 • No cases of spontaneous Arch Surgery;131,611-618,1996) Etiology: Case Reports • Infectious • • • • • • • – HSV esophagitis – Candida esophagitis – Tuberculosis Eosinophillic esophagitis Pill induced esophagitis Reflux esophagitis/ulceration Barrett esophagus/ulcers Zollinger Ellison Syndrome Behcet’s disease Interesting lack of crohn dz and NSAIDs Clinical Presentation • Spontaneous esophageal perforation – Middle age man – Dietary over indulgence and alcohol consumption – Mackler’s triad: Chest pain, subcutaneous emphysema, and recent vomiting/retching • Will depend on: – Location of perforation – Etiology of the perforation Cervical • Subcutaneous emphysema most common – Found in 90% • • • • • • Spread to mediastinum is slower Dysphagia Dyspnea Neck pain Dysphonia Bloody regurgitation Thoracic • • • • • Rapidly contaminate the mediastinum May spread to pleural cavity as well, L>R Mediastinal and subcutaneous emphysema Involvement of pericardium has been reported Inflammatory response – Chest pain: Retrosternal, can spread to arms, back, and shoulders – Tachycardia, tachypnea, grunting, dyspnea, resp distress – Hypovolumia – Leukocytosis • Systemic sepsis and shock with in hours Abdominal • Uncontained and results in contamination of the peritoneal cavity • Back pain and difficulty lying supine • Epigastric abdominal pain and dysphagia – Maybe referred to the shoulder • Fever, tachycardia, tachypnea, • Rapid deterioration to sepsis and shock Clinical Manifestations: Neonates • History of difficult ET or NG tube placement • Hypersalivation • Coughing/choking/cyanosis with feedings • Pneumothorax • Fever • Bloody drainage from gastric tube Differential Diagnosis • Peptic ulcer with perforation • Acute pancreatitis • Spontaneous pneumothorax and mediastinum • Pneumonia • Aortic aneurysm dissection • Acute myocardial infarction Diagnosis • History of esophageal manipulation or trauma • Otherwise requires high index of suspicion • Initial tests: AP and lateral CXR – May show • Pleural effusion, pneumothorax, subcutaneous emphysema, pneumomediastinum, pneumopericardium, subdiaphargmatic air – May also be normal in 12-33% Contrast Radiography • Establishes diagnosis/localizes injury • Water soluble contrast – Most recommend this first • Limitations • Thin barium (greater density) – Improves sensitivity to 60% in cervical and 90% in thoracic perforations – May cause inflammatory reaction in pleural space • Three injury patterns – Retropharyngeal collection – Contrast tracking parallel and posterior to the esophagus – Free perforation into pleural space Could this be congenital H type TEF? • No – Bronch showed normal trachea – Symptom free till recently – Esophageal and gastric ulcers • Yes: never say never – Case report dx H type in 10 yr girl dx by esophagoscopy and bronchoscopy – Their literature review noted 3 pts over age 10 yrs dx with H type fistula • CLIN PEDIATR February 1996 vol. 35 no. 2 103-104 Diagnosis Computed Tomography • Some institutions use CT with oral contrast as primary modality after plain films • Trend in US is for contrast esophagram • Some advocate use of both in all patients with suspected esophageal perforation Endoscopy • Various recommendations • Pros – May better localize size and location – May aid in diagnosis of cause if unknown • Cons – May worsen injury – Inferior to contrast study Management • Historically based on adult reports – Adult surgeons favored direct surgical repair • Kids esophagi are not little adult esophagi – Adult perfs have more underlying pathology – Kids have increased propensity to heal and often difficult to localize leak • Case series in 1988 (N=12) – All patients treated conservatively – All but 1 healed without need of surgery J of Thoracic Cardiovasc Surgery 1998:95:692 Management: Conservative • Basic Tenant: promote spontaneous healing – Minimize proximal flow, prevent contamination, maintain downstream flow, support nutrition • Broad spectrum antibiotics for 7-14 days – Cultures usually grow polymicrobial organisms • NPO and gastric drainage • Nutrition – TPN if unable to secure enteral access – Enteral • Tube placement: endoscopy, fluoroscopy, place tube in perforation • Resuming oral feeds – When repeat esophagram shows no leak – Average time to esophagram 7 day, restarting feeds 11 days • Thoracostomy tube Management: Conservative Works Best If: • • • • Perforation is instrumental Perforation is cervical in location Perforation is detected early (<24hrs) Perforation is well contained Back to the Case • Esophageal perforation, etiology unknown led to mediastinitis – Suspect reflux related – Possibly iatrogenic or spontaneous • Previous pericarditis – Could this have been related to esophageal perforation and esophagopericardial fistula? Esophagopericardial fistula • Case review (n=49) AJR 141:171-173;July 1983 • Etiology – #1 etiology was esophagitis/esophageal ulcer (75%). Many of these patients had previous reflux or hiatal hernia surgery • Radiographs – Pneumopericardium in 50% – Pneumomediastinum in 17% • Recent case report in a 1yr old Chest Pain • Chief complaint: chest pain • Peds cardiology referral 2nd to murmur • Musculoskeletal most common – 15-30% prevalence • Non-cardiac 98% of the time • More likely cardiac if – Increases with exertion, s/s myocardial ischemia and abnormal cardiac exam – Pediatr. Rev. 2010;31;e1-e9 Chest Pain: Gastrointestinal • Gastrointestinal 8% of the time – GERD and PUD • epigastric, burning, regurg, related to eating, respond to acid blockade – Esophageal spasm or inflammation – Atypical • cholecystitis • esophageal foreign body, strictures, ingestions Chest Pain: Pericarditis • With or without effusion • Usually infectious in nature • Character – Sharp, retrosternal, radiates to left shoulder • Worse with supine position and inspiration • Improves with bending forward Chest Pain: Mediastinitis • Character – Severe and substernal • Worse with inspiration and coughing • Radiates to neck or interscapular area Summary • Esophageal perforation is rare in children and most commonly iatrogenic • Mediastinits/pneumomediastinum • Diagnosis is based on contrast esophagram with +/- CT and endoscopy • Early diagnosis and treatment helps limit morbidity and mortality • Trend toward conservative treatment
