leave it…. or heave it: indications for foreign body removal
LEAVE IT…. OR HEAVE IT: INDICATIONS FOR FOREIGN BODY REMOVAL Wendy Jeshion, MD Co-Section Chief Pediatric Gastroenterology & Nutrition Joseph M. Sanzari Children’s Hospital Hackensack University Medical Center Foreign Bodies (FB) • Responsible for 1500 deaths each year in the US • 80% of all FB occur in the pediatric patient • Most common gastrointestinal FB in children coins button batteries food impaction toys pins crayons magnets pen caps Foreign Bodies (FB) • 80-90% of FB will pass spontaneously with an average transit time of 4-7 days • 10-20% will require endoscopic intervention • 1% will require surgery Complications of FB • • • • • Esophageal perforation Airway obstruction Aspiration Intestinal perforation Tracheoesophageal or esophagoaortic fistula formation • Volvulus • Death Symptoms • • • • Dysphagia Odynophagia Sensation of foreign body Even if foreign body passes, many children complain of pain referable to cervical esophagus • In children, symptoms more commonly include drooling, vomiting or gagging Types of Foreign Bodies (FB) • Coins • Magnets • Button Batteries • Sharp/Pointed objects • Food Impaction Coins Coins – Evaluation Criteria • • • • • Length of time since coin swallowed Symptomatic Previous Surgery Age of the child and type/size of coin Location of coin (AP and lat CXR) X-ray Coin in Esophagus Coins by Size • Coins smaller than 20mm usually pass • Dimes (17mm) • Pennies (18mm) usually pass easily • Quarters (23mm) • Nickels (21mm) usually don’t pass Coins by Location - Esophagus • Most common sites of impaction are at the thoracic inlet, aortic arch, and LES • Lodged in the pharynx or at the level of the cricopharyngeus- ENT/surgery - rigid scope • Distal esophagus and asymptomatic- can wait up to 24 hours to let it pass • Consider glucagon (0.5-1.0 mg) Coins by Location - Esophagus • Remove within 24 hours secondary to complications of ulceration, perforation, and fistula formation • Bougie vs. foley vs. metal detector. vs. endoscopy • Endoscopy- alligator or rats tooth grasping forceps • Must protect the airway Esophageal Coin Removal Fifty Cents Coins by Location - Stomach • Asymptomatic- can allow 4-6 weeks to let it pass before retrieving; follow with xrays and examination of stool • Coins smaller than 20mm will pass spontaneously • Now must remove pennies secondary to increased zinc in the pennies • Atypical coins often corrosive Chuck E. Cheese Carousel Craze Magnets Case: • 17 yr old male with autism and pica who complained of 1 week h/o vague abdominal pain. No other symptoms present • AXR with 14 radioopaque objects scattered throughout GI tract Magnets in the Stomach Magnets Magnets Magnets • Small and powerful magnets are being used more commonly in children’s toys • CPSC aware of numerous injuries and deaths secondary to magnet ingestions • Ingestion of multiple magnets or coingestion with a metallic object can pose unique health hazards to children Magnets Intestinal obstruction, perforation, fistula formation, volvulus, ischemia, death Multiple magnets should be endoscopically removed if possible Ingestion of multiple magnets and signs of intestinal obstruction need emergent surgical evaluation CPSC announced recalls of numerous magnetic sets Pediatricians should include the dangers of detachable magnets in toddler safety discussions Button Batteries Button Batteries (BB) • 3,500 cases of BB ingestions reported to poison control centers annually • Batteries from watches, remote controls, hearing aides, cameras, calculators, singing greeting cards, and toys • 90% of the batteries pass spontaneously. • Complications include perforation, mediastinitis, stricture, tracheoesophageal fistula, and death • Sevenfold increase in the number of severe complications from BB ingestion in the past few years (from 0.5% to 3%) Button Batteries • Newer batteries stronger than the older batteries. • Lithium batteries starting with number 20 are responsibly for 90% of serious injuries. • Federal safety rules require toys with BB to have battery compartments locked with screws • Devices for adults often have simple plastic cover Button Batteries • Can be true medical or surgical emergency • BB contain 25- 45% solution of either potassium or sodium hydroxide • BB cause tissue injury by: – Low-voltage electrical burns – Pressure necrosis – Corrosive injury due to liquefaction necrosis from leakage of alkaline solution Button Batteries - Management • Tx depends on location- need immediate X-rays • Ipecac not recommended • Administration of charcoal or neutralizing solution is not helpful Management of Esophageal BB • Urgent endoscopic removal if lodged in the esophagus. • Esophageal damage can occur within 2 hrs after ingestion • Once remove battery, must inspect for mucosal damage • If there is a tissue damage, Barium swallow should be obtained 24-36 hrs later to r/o fistula • Repeat Ba swallow 10-14 days later to r/o stricture or fistula Management- BB in the Stomach • In the stomach- can be more conservative • All but the largest (>20 mm) should pass • May be treated as an outpatient. ( Parents to strain the stools) • Repeat abdominal film in 48 hrs if doesn’t pass. If still in stomach - remove endoscopically. Management- BB past the Pylorus • Repeat films until battery passed • Can get “hung up” in the ileocecal valve • Surgical removal if BB fails to move after 5 days or pt develops abdominal pain or peritoneal irritation Sharp/Pointed Objects Case: 2 yo girl swallowed a barrette two hours ago. No abdominal pain, vomiting, or respiratory symptoms. CXR confirms that the 5 cm barrette is located in the stomach. Barrette in Stomach Sharp/Pointed Objects Account for 10% of FB ingestions, but responsible for most # of GI complications Bones, pins, toothpicks, nails, razors, glass 15-35% of perforations are from sharp objects Perforations usually occur in the duodenum, ligament of Treitz, ileocecal valve Sharp Objects in the Esophagus X-ray to document location. Esophageal sharp objects should be removed immediately High risk objects often need to be removed with an overtube (glass, open safety pin, razors, & needles) Overtube for endoscopic removal Sharp Objects in the Stomach Longer than 5cm (3 cm for a toddler) or greater than 2 cm in diameter unlikely to pass High risk objects (bones, long straight pins, razors, & toothpicks)-remove immediately Can manage small nails, screws, pins, & thumbtacks more conservatively Pointed Objects Sharp Objects past the Pylorus Bowel has a “mural withdrawal reflex” Bowel reflexively dilates in response to contact with a sharp object Reflex turns sharp objects; leaving the sharp end trailing and preventing perforation Sharp Objects past the Pylorus • High roughage diet • Serial abdominal x-rays and evaluation for symptoms • If a sharp object stays in one place for 5 days or the patient develops symptoms must be surgically removed. Food Impaction Spaghetti …and Meatball Underlying Stricture Food Impaction Hot dogs, chicken, and meat Consider underlying GI problem Strictures Eosinophilic esophagitis X-ray only helpful to check for bones Barium studies can lead to aspiration Food Impaction If asymptomatic; can wait up to 12 hrs to remove Can try glucagon if asymptomatic Do not try papain/meat tenderizer Drooling- urgent endoscopy required Food should not be pushed into the stomachremove in fragments If the impaction passes, still needs an endoscopy in the near future to evaluate for potential GI pathology Case • 11 yr old boy who began drooling after eating chicken. Vomits after the introduction of any liquids. In ER pt continues to drool or spit out his secretions. Otherwise asymtomatic. • PMHx is remarkable for seasonal allergies • Upon review, the patient has had some mild episodes of dysphagia in the past Chicken Impaction Eosinophilic Esophagitis Normal Esophagus Eosinophilic Esophagitis Eosinophilic Esophagitis (EE) • Marked rise in EE in pediatric and adult population • Pts with EE can have food impaction from dysmotility, edema, or stricture formation • School aged children and adults with EE often present with food impaction as their initial presentation of the disease • Important to ask about dysphagia in pts with reflux symptoms and h/o atopy • Patients with feeding aversion should have a work up for EE The End
