Clinical & Coding Specifications
Clinical Context
A 42-year-old patient with prior Roux-en-Y gastric bypass presents with progressive weight regain and dilation of the gastrojejunal anastomosis and gastric pouch, causing decreased satiety and increased meal size. After multidisciplinary evaluation including bariatric surgery, nutrition, and behavioral health, the patient is scheduled for an endoscopic outlet reduction procedure. The procedure is performed in an endoscopy suite or ambulatory surgery center under monitored anesthesia care or general anesthesia. An upper endoscope is introduced to visualize the gastric pouch and outlet; endoscopic suturing or tissue-anchoring devices are used to reduce the stoma diameter and reshape the pouch. If indicated, an intraluminal tube may be inserted for guidance or tissue approximation. The workflow includes preoperative consent and focused history, anesthesia evaluation, intra-procedural endoscopy with device deployment, immediate post-procedure recovery with monitoring for bleeding or perforation, discharge with dietary progression instructions, and scheduled follow-up for symptom assessment and possible repeat endoscopic revision if restenosis or inadequate restriction occurs.
