From the Guidelines

Neither soap suds enemas nor magnesium citrate are recommended for removing foreign objects from the rectum. The safest approach is to seek immediate medical attention at an emergency department or urgent care facility, as stated in the guidelines by the World Journal of Emergency Surgery 1. Healthcare professionals have specialized tools and techniques to safely remove rectal foreign bodies without causing further injury. Attempting to remove objects yourself using enemas or laxatives can potentially push the object further into the colon, cause perforation of the bowel wall, or lead to other complications such as bleeding or tissue damage.

Key Considerations

  • Medical professionals will typically use gentle manual extraction techniques, sometimes with sedation if needed, and may employ specialized instruments or endoscopic procedures for objects located higher in the rectum, as suggested by the guidelines 1.
  • They can also assess for any damage that may have occurred and provide appropriate follow-up care.
  • Rectal foreign bodies are a relatively common medical emergency, and healthcare providers are trained to handle these situations professionally and without judgment.
  • In patients with retained anorectal foreign body and failure of bedside extraction, pudendal nerve block, spinal anesthesia, intravenous conscious sedation, or general anesthesia may be used to improve chances of transanal retrieval 1.
  • For high-lying anorectal foreign bodies, endoscopic extraction is suggested as the first-line therapy 1.

Important Recommendations

  • In patients with retained anorectal foreign body, a proctoscopy or flexible sigmoidoscopy should be performed after foreign body removal to evaluate bowel wall status 1.
  • If there are signs of hemodynamic instability or perforation, transanal extraction is not recommended 1.
  • The treatment approach may vary depending on the location, type, and number of foreign bodies, as well as the patient's clinical situation 1.

From the Research

Removal of Rectal Foreign Bodies

  • The use of soap suds or magnesium citrate for removing a foreign object from the rectum is not mentioned in the provided studies 2, 3, 4, 5, 6.
  • According to the studies, removal methods for rectal foreign bodies include:
    • Manual extraction without anesthesia for low-lying objects 3, 4
    • Manual extraction under local or general anesthesia 3, 4, 5
    • Endoscopic removal 5
    • Laparotomy with repair of complications 3, 4, 6
  • The choice of removal method depends on the type and location of the foreign body, as well as the patient's condition 3, 4.

Important Considerations

  • Rectal foreign bodies can cause serious complications, such as perforation, peritonitis, and rectal trauma 3, 4, 6.
  • Prompt and proper treatment is essential to prevent these complications 3, 4.
  • A high index of suspicion is required to accurately diagnose a rectal foreign body, as patients may be embarrassed about their condition and not present in a timely fashion 5.
