Rectal perforation during defecography: extraluminal barium impaction removed by TEM (Transanal Endoscopic Microsurgery)
Main Article Content
Abstract
AIM: Defecography is the standard diagnostic technique for the diagnosis of functional disorders of the posterior pelvic compartment. However it has some limits as radiation exposure, low-contrast resolution, some degrees of embarrassment and discomfort for the patients. Furthermore it often fails to directly visualize the changes that affect the pararectal space. Here we present a never described case of rectal perforation after defecography with barium impaction removed by TEM (Transanal Endoscopic Microsurgery).
CASE REPORT: We present a case of a 50 years old woman with extraluminal barium impaction due to perforation occurred during defecography. Both pelvic MR and endoanal ultrasound confirmed the presence of the extramural rectal mass below rectal mucosa. It was completely and safely removed using transanal endoscopic microsurgery (TEM).
RESULTS: The barium impaction has been radically removed using transanal endoscopic microsurgery. The post-operative period was uneventful and the patient was discharged 3 days after the operation. She is asymptomatic after 6 months from surgery.
CONCLUSION: Defecography is not completely safe and its use must be indicated only in selected cases. When a patient has complications during or after this investigation he must be referred to a specialistic centre where a tailored treatment can be performed. It is mandatory that the indication for defecography and other diagnostic functional investigations is given by a colorectal specialist
