Yes, Endoscopy Can Perforate the Esophagus: Rare on Diagnostic EGD, Close It If You See It
Diagnostic risk is tiny. Dilation, foreign body, and resection raise it. Immediate recognition is the difference between a clip and a thoracotomy.
Honor the slug: endoscopy can perforate the esophagus. Diagnostic EGD almost never does. Therapeutic work (dilation, foreign body, EMR/ESD, pneumatic dilation) does more often. ESGE 2020 (Paspatis, PMID 32781470) and AGA 2021 (Lee, PMID 34224876): if you see it, stop, use CO2, suction, NPO, IV antibiotics, call surgery, get CT, and close what you can. Boerhaave is transmural rupture from retching, not a scope injury.
Experienced teaching points
Clinical Pearls
- Diagnostic EGD perforation is rare. Do not scare a screening patient with thoracotomy language. Do warn before dilation, foreign-body work, or resection.
- If you see the tear: stop insufflation, switch to CO2 if you are still in, suction, NPO, broad-spectrum antibiotics, surgical consult, CT.
- Close when you can: TTS clips for small defects, OTSC for larger ones under about 2 cm, SEMS when you cannot approximate edges. EVT is a selected leak tool.
- Delayed recognition with mediastinitis is a surgical and ICU problem. Endoscopy is not the whole plan.
- Spontaneous transmural rupture: Boerhaave. How you dilated: dilation. Clip vs OTSC: TTS and OTSC bleed. Achalasia workup: Chicago 4.0.
Clinical Bottom Line
| Situation | Move |
|---|---|
| Diagnostic EGD | Perforation is rare. The honest answer to the slug is yes, it can, and almost never does. |
| Higher-risk therapy | Dilation (especially pneumatic for achalasia), sharp foreign body, stricture incision, EMR/ESD, POEM. Consent should say so (AGA 2021, PMID 34224876). |
| Recognized immediately | Stop. CO2. Suction. NPO. IV fluids and broad-spectrum antibiotics. Surgical consult. Close if feasible: TTS under about 10 mm, OTSC under about 2 cm, SEMS when you cannot close (ESGE 2020, PMID 32781470; AGA BPA 8). |
| Uncertain or delayed | CT with water-soluble contrast. Do not feed on a prayer. Collections need drainage. Delayed mediastinitis is not a clip case. |
| Not this page | Spontaneous transmural rupture after retching is Boerhaave. Mallory-Weiss is mucosal. There is no Mallory-Weiss slug; keep that distinction on Boerhaave. |
So can endoscopy damage the esophagus?
Yes. Diagnostic EGD almost never does. The leftover stub opened with mediastinal doom language and treated Boerhaave as an automatic thoracotomy. Drop that. Iatrogenic injury recognized in the room is often closable. Paspatis 2020 (Endoscopy 2020;52:792-810, PMID 32781470) and Lee 2021 (PMID 34224876) are the two citations: NPO, antibiotics, early surgery consult, imaging, and endoscopic closure when the defect is fresh and reachable. Fully covered SEMS is for defects you cannot approximate or for malignant holes that also need a lumen. Endoscopic vacuum therapy is a selected option for leaks, not a first move on a 6 mm fresh tear you can clip.
A give during pneumatic dilation is the classic miss if you keep pushing air and send the patient to recovery. Look. If the mucosa is open, treat it now.
When is this not a scope injury?
Retching that splits the full thickness of the distal esophagus is Boerhaave. Mucosal bleeding at the GEJ after vomit is Mallory-Weiss. Neither is "the endoscope tore it" unless you were there. Do not restage CT-first Boerhaave care or how to pick a dilator here.
