Typical Clinical Scenarios

An older adult presents emergently with severe upper abdominal pain, persistent vomiting, dehydration, and imaging showing a perforated pyloric ulcer with necrotic tissue involving the pylorus; the patient is taken to the OR for removal of the devitalized pyloric segment to control sepsis and perforation without reconstruction. Typical codes: 0DT70ZZ
A middle-aged patient with chronic gastric outlet obstruction from refractory pyloric stenosis after failed endoscopic dilation is admitted electively for definitive surgical management; the surgeon performs a planned resection of the pyloric channel to relieve the obstruction, using a percutaneous endoscopic approach. Typical codes: 0DT74ZZ
A patient with a malignant lesion centered in the pylorus causing bleeding and obstructive symptoms undergoes an endoscopic transoral procedure to excise the tumor-bearing pyloric tissue for palliation without immediate reconstruction of the stomach. Typical codes: 0DT78ZZ
