Typical Clinical Scenarios

An elderly patient presents to the emergency department with sudden-onset severe epigastric pain, persistent vomiting, and signs of sepsis after days of gastric outlet obstruction from a known pyloric stenosis; imaging shows fluid collection/retained secretions localized to the pyloric region requiring prompt evacuation to relieve obstruction and control infection. An open surgical drainage of the pylorus may be performed if percutaneous access is not feasible due to adhesions or patient instability. Typical codes: 0D970ZZ, 0D9700Z
A middle-aged patient with malignant gastric outlet obstruction from an advanced pyloric tumor is admitted for symptom palliation and planned endoscopic internal drainage to decompress retained gastric contents and improve oral intake; the procedure is performed electively via a percutaneous endoscopic approach to place a drainage device. Typical codes: 0D9740Z, 0D974ZZ
A postoperative patient develops an abscess localized to the pyloric region after partial gastrectomy, with persistent purulent drainage despite antibiotics; percutaneous image-guided aspiration and placement of a drainage catheter is performed to control the infectious collection as a nonoperative salvage measure. Typical codes: 0D9730Z, 0D973ZZ
