Summary
Subcutaneous emphysema is a rare complication following colonoscopy, often resulting from minor colon wall tears. Conservative treatment is typically effective, leading to excellent patient outcomes without lasting effects.
Area of Science:
- Gastroenterology
- Endoscopic Procedures
- Surgical Complications
Background:
- Colonoscopy with polypectomy is a common gastrointestinal diagnostic and therapeutic procedure.
- Complications, though rare, require prompt recognition and appropriate management.
- Understanding potential adverse events is crucial for patient safety.
Observation:
- A 71-year-old male developed extensive subcutaneous emphysema post-colonoscopy and polypectomy.
- Emphysema affected the abdomen, chest, mediastinum, scrotum, and legs.
- Symptoms appeared hours after the procedure, with the patient initially discharged.
Findings:
- Subcutaneous emphysema resulted from a small colon mucosal laceration allowing air into the retroperitoneum (extraperitoneal perforation).
- This rare complication is associated with aggressive endoscopic instrumentation.
- Conservative management, including bowel rest and supportive care, was initiated.
Implications:
- Extraperitoneal perforation from colonoscopy typically does not require surgical intervention.
- Conservative treatment leads to gradual resolution of emphysema and excellent prognosis.
- Highlights the importance of recognizing and managing rare endoscopic complications conservatively.
