Piercings During Medical Procedures: Endoscopy, Biopsy, and Outpatient Interventions

The middle ground between routine and surgery

Between routine dental appointments and full surgery sits a large category of medical procedures: endoscopy, colonoscopy, biopsies, catheterisation, ambulatory interventions, day-case procedures. Each has its own equipment, positioning, and requirements. And each has its own piercing considerations, often not obvious from general internet advice.

This guide covers common medical procedures and what to expect for piercings during each. The general principle: outpatient procedures often allow more piercings to stay than full surgery, but specific procedures near piercing sites or involving specific equipment (electrocautery, imaging, sedation) still require removal or retainers.

 

Endoscopy and colonoscopy

Upper endoscopy (gastroscopy)

•         Passes a flexible tube through the mouth into the stomach

•         Oral piercings must be removed (tongue, lip, cheek) for tube access and safety

•         Other piercings can typically stay

•         Sedation is common but usually conscious sedation rather than general anaesthetic

•         Plan for oral piercings to be out for the procedure day, reinsert once fully alert

Colonoscopy

•         Examines the colon via the rectum

•         No specific piercing removal required for most piercings

•         Sedation is common (conscious sedation, sometimes deeper sedation)

•         Genital piercings may be asked to be removed depending on positioning

•         Standard preparation (bowel prep the day before) does not affect piercings

Flexible sigmoidoscopy

•         Shorter version of colonoscopy, examines lower colon only

•         Usually less or no sedation

•         Similar piercing considerations to colonoscopy but even less restrictive

Bronchoscopy

•         Examines airways via mouth or nose

•         Oral and facial piercings usually removed for equipment access

•         Other piercings can stay

•         Local anaesthetic to the throat, sometimes with conscious sedation

 

Biopsies

Skin biopsies

•         Punch, shave, or excisional biopsies of skin lesions

•         Piercings need to be removed only if in the biopsy area itself

•         Local anaesthetic, no general sedation typically

•         Piercings elsewhere on the body can stay throughout

Needle biopsies (breast, thyroid, prostate, other)

•         Fine needle or core needle biopsies guided by ultrasound or CT

•         Piercings in the biopsy area need to be removed

•         If ultrasound guidance is used, piercings that would interfere with the probe placement need removal

•         If CT guidance is used, piercings in the imaging field affect image quality (see the X-rays/CT cluster)

•         Sedation is uncommon for needle biopsies

Surgical biopsies

•         Larger biopsies performed in operating room settings

•         Follow surgical protocols (see the surgery cluster guide)

•         General anaesthetic considerations apply

 

Catheterisation and vascular procedures

Urinary catheterisation

•         Genital piercings may need to be removed for catheter insertion

•         Discuss with the medical team specifically about your specific piercings and the type of catheter

•         Other piercings can stay

Cardiac catheterisation

•         Access typically via wrist or groin

•         Piercings at the access site (rare in these locations) must be removed

•         Other piercings can typically stay

•         Electrocautery is not used in standard cardiac catheterisation, so metal in other areas is not a specific concern

•         However, defibrillator readiness during cardiac procedures may prompt broader removal

IV placement

•         Basic IV placement rarely affects piercings unless the IV site is very close to a piercing

•         The most common IV sites (forearm, hand) are usually far from typical piercings

•         Piercings can stay throughout IV placement

 

Anaesthetic and sedation considerations

Local anaesthetic only

•         Minimal piercing considerations, only the immediate procedure area matters

•         Piercings elsewhere can stay throughout

Conscious sedation (light to moderate)

•         You remain able to breathe and respond, but consciousness is reduced

•         Oral piercings usually removed as a precaution for airway safety

•         Other piercings depend on procedure specifics

Deep sedation

•         Approaches general anaesthetic in effect

•         Oral piercings must be removed

•         More extensive piercing considerations, closer to surgery protocols

General anaesthetic

•         Full surgical protocol applies (see the surgery cluster guide)

•         Oral and facial piercings almost always removed

•         Other piercings depend on procedure specifics

 

Common outpatient procedures and their specifics

Procedure	Typical piercing requirements
Gastroscopy	Oral piercings out, others can stay
Colonoscopy	Genital piercings may need removal; others usually stay
Bronchoscopy	Oral and facial piercings out; others stay
Skin biopsy	Only piercings in the biopsy area affected
Breast biopsy (needle)	Nipple piercing on affected side removed; others stay
Thyroid biopsy	Neck-area piercings removed; others stay
Cardiac catheterisation	Access-site piercings removed (rare); others stay
IUD insertion or removal	Genital piercings may need removal; others stay
Vasectomy	Genital piercings out; others stay
Cystoscopy	Genital piercings out; others stay
Angiogram	Access-site piercings out; others depend on imaging area
ECG or holter monitor	Chest and nipple piercings removed for electrode contact
Ultrasound (routine)	Only piercings in the imaging area affected

 

Emergency procedures

Unscheduled procedures do not allow time for careful jewellery removal preparation. In genuine emergencies, the medical team removes what they need to remove quickly, potentially cutting jewellery if time does not permit careful removal. Priorities in emergencies.

•         Disclose piercings as early as possible, even in the emergency context

•         Do not try to remove piercings yourself if you are unwell, let the medical team do it

•         Do not hide piercings hoping they will be missed, this creates dangerous situations if the team discovers them mid-procedure

•         Piercings can be re-pierced later, complications from delayed emergency care cannot be undone

 

Reinserting after outpatient procedures

•         Wait until any sedation has fully worn off (typically 12 to 24 hours)

•         Clean hands thoroughly before touching piercings

•         Follow the medical team's specific timing guidance if given

•         Do not reinsert until any local swelling or tenderness in the piercing area has resolved

•         If the piercing feels tight, do not force jewellery through, use retainers first to reopen gradually

•         Standard aftercare applies if any piercings had jewellery replaced

Frequently Asked Questions

Do I need to remove my piercings for an endoscopy?

Oral piercings (tongue, lip, cheek) must be removed for upper endoscopy (gastroscopy) because the flexible tube passes through the mouth. Facial piercings usually can stay. Ear and body piercings can stay throughout. Colonoscopy typically does not require removal of most piercings; genital piercings may need removal depending on positioning. Confirm specifics with the endoscopy team when you arrive.

What piercings need to come out for a colonoscopy?

Usually none, except potentially genital piercings depending on positioning. Colonoscopy examines the colon via the rectum, and most piercings are not in the surgical field or affected by the equipment. Sedation is common but typically conscious sedation, not general anaesthetic, so airway concerns are minimal. Genital piercings may be asked to be removed depending on the specific positioning and equipment used. Discuss with the endoscopy team when you arrive.

Do I need to remove piercings for a biopsy?

Only piercings in the biopsy area itself. Skin biopsies (punch, shave, excisional) require removal of piercings within the biopsy area. Needle biopsies (breast, thyroid, prostate) require removal of piercings in the area being biopsied. Piercings elsewhere on the body typically can stay throughout. Ultrasound or CT-guided biopsies may require removal of piercings in the imaging area as well, see the X-rays/CT cluster guide for imaging-related considerations.

Should I remove piercings for cardiac catheterisation?

Only piercings at the access site (usually wrist or groin), which is uncommon for typical piercing positions. Other piercings can usually stay. Cardiac catheterisation does not use electrocautery in most standard procedures, so metal elsewhere is not a specific safety concern. However, defibrillator readiness during cardiac procedures may prompt more conservative removal protocols at some facilities. Discuss with the cardiology team before the procedure.

Can I keep my ear piercings during a colonoscopy?

Yes. Ear piercings are far from the procedure area, do not interact with equipment, and do not affect the imaging or intervention. Colonoscopy typically requires removal of only genital piercings depending on positioning, and even those are situation-specific. Ear, facial, and body piercings above the waist can stay throughout the procedure and recovery.

Do I need to remove piercings for an IUD insertion?

Genital piercings may need removal for IUD insertion or removal, discuss with the medical team specifically. The specific piercing position matters, some do not interfere with the procedure while others do. Other piercings can stay. IUD procedures are typically done without anaesthetic or with local anaesthetic only, so piercing considerations are procedure-specific rather than sedation-related.

What if my procedure requires an ECG or Holter monitor?

Chest and nipple piercings need to be removed for the electrodes to make proper contact with the skin. The adhesive pads used for ECG monitoring need direct skin contact, and metal jewellery interferes with electrical signal quality. Ear and facial piercings can stay. Body piercings elsewhere can stay unless they are directly under an electrode position. Standard ECG placement uses chest, arm, and leg positions.
