What does DMR mean in UNCLASSIFIED

DMR is a minimally invasive endoscopic procedure used to treat duodenal mucosal lesions, such as refractory peptic ulcers or scar tissue that obstructs the passage of food or fluids. It involves controlled removal and regeneration of the duodenal mucosa using an electrosurgical snare.

DMR is performed to remove or modify abnormal duodenal mucosa that causes symptoms such as persistent pain, bleeding, or obstruction. It can also be used as a diagnostic tool to obtain tissue samples for biopsy.

Individuals with refractory duodenal ulcers, obstructions, or bleeding that have not responded to conventional treatments may be considered for DMR. It is typically performed when other endoscopic or surgical options are not suitable or have failed.

DMR is performed using an endoscope inserted through the mouth. The endoscope is equipped with an electrosurgical snare that delivers controlled electrical energy to remove the targeted mucosal tissue. The procedure typically takes 30-90 minutes.

As with any endoscopic procedure, there are potential risks associated with DMR, such as bleeding, infection, and perforation of the duodenum. However, these risks are generally low and occur in less than 5% of cases.

DMR has shown promising results in treating refractory duodenal lesions. Studies have reported significant improvement in symptoms, ulcer healing, and reduction in bleeding. Long-term outcomes are generally favorable, with low recurrence rates.

Patients typically experience minimal discomfort after DMR and can resume normal activities within a few days. A liquid or soft diet may be recommended for a short period to allow the mucosal lining to heal.
