This document discusses the approach to foreign body ingestion. It begins with an introduction noting that foreign bodies in the gastrointestinal tract are generally not as dangerous as those in the airway. It then covers what types of objects are commonly ingested, who is most at risk, where in the GI tract objects typically lodge, clinical features, investigations like x-rays, and management approaches like endoscopic removal or conservative monitoring. Endoscopy is highlighted as the preferred minimally invasive method for removing ingested objects.

3. INTRODUCTION
O FBs of GIT are not so dangerous as air
way foreign bodies.
O very common problem among children
and elderly
O 80-90 % pass harmlessly
O 10–20% will require endoscopic
intervention
O < 1% will require surgery

9. HISTORY
O Did you witness the child ingesting a foreign
body?
O Did the child report to you that he/she ingested a
foreign body?
O Do you know what the foreign body is? (size,
shape, identity)
O Do you know when the child ingested the foreign
body?
O Have you found the foreign body in the
stool/vomitus already?

10. O Does the child have any other medical
illnesses or have had previous surgery?

Stools? If so, how many times, what
color?

13. PHYSICAL EXAMINATION
O Usually unremarkable
O Oral cavity/oropharynx/Neck :
• Drooling or pooling of secretions
• Impacted FB : hypopharynx
• Crepitus ,swelling : neck
O Per Abdomen: tenderness, rigidity,distention
(perforation/ obstruction)
O Chest : wheeze , stridor

15. 2.Neck /Chest/Abdominal Radiography
O Initial Investigation of choice
O Most ingested foreign bodies are radiopaque
(60%)
Determines :
O Presence
O Type
O location of the foreign body.
O Identifying possible complications

19. 3.Metal detectors:
• Identification of metallic FB
• Aluminum FB - often radiolucent.
• look for progresssion of metallic FB in
GIT
4.Endoscopy:
O diagnostic and therapeutic
O Radiolucent FB
5. CT- Scan :
• Non metallic ,radiolucent FB

O Length> 10cm
O Any object
Child: >1cm X 3cm
Adult: > 2cm X 5 cm
O Symptomatic, f/o perforation
O Esophageal FB (> 24 hrs at presentation)
O Sharp ,pointed FB
O Batteries remaining in the stomach (> 48 h )
3/15/2018APPROACH TO FOREIGN BODY INGESTION 21
22. Conservative management
(wait and watch )
O Coins in the esophagus : 12–24 Hrs
O Any asymptomatic blunt object : 1week
Child: <1cm X 3cm
Adult: < 2cm X 5 cm
O Asymptomatic Disk batteries and
cylindrical batteries in stomach : upto 48
Hrs.
O Progression ; serial xrays , metal detector
O laxatives to increase GI motility

23. Methods of removal
1.Endoscopy
O Procedure of choice
O Minimally invasive
O Success rate: 90-100%
O Can retrive FB up to 2nd part of duodenum
(FB beyond that often passes spontaneously)

formation, obstruction.
O FB fail to progress (lie beyond stomach)
O FB not retrieved endoscopically.

Respiratory symptoms due to esophageal foreign body is common in
children because of their small and compressible tracheal lumen
occasionally reveal an impacted foreign body in hypopharynx
. There is a coin (a magnified US nickel) (white arrow) in the esophagus, impacted at the level of the aortic arch. The coin exceeds the diameter of the trachea (black arrows) so that it can not lie within the trachea.
C- shaped cartilagenous ring ,defect posteriorly ,FB end on
Between swallows the esophagus is collapsed but the lumen can distend to approximately 2 cm in the anterior-posterior dimension and up to 3 cm laterally to accommodate a swallowed bolus. he cricopharyngeus (CP) muscle is a striated muscle attached to the cricoid cartilage. It forms a C-shaped muscular band that produces maximum tension in the anteroposterior direction and less tension in lateral direction.coin face en

However, on closer examination of both the lateral and A-P radiographs, it was obvious that the coin was aligned alongside and outside of the tracheal air column .
