How long does it take to perform an ERCP with stent insertion?

The duration of an ERCP with stent insertion typically depends on the complexity of the procedure, the underlying condition, and whether additional interventions are needed. Here’s a general overview:

Average Procedure Duration

• Simple ERCP with stent placement: 30–60 minutes.

• For straightforward cases, such as placing a stent for a benign stricture or stone removal, the procedure is relatively quick.

• Complex ERCP with stent placement: 60–120 minutes.

• Cases involving multiple stents, advanced techniques, or treating complications (e.g., removing large stones or tumors) can take longer.

Factors Affecting Procedure Time

1. Type of Stent

• Plastic stents: Easier and quicker to insert; often used for temporary solutions.

• Metal stents (SEMS): May require additional preparation and precision, slightly increasing the time.

2. Underlying Condition

• Simple blockages (e.g., small stones): Faster procedure.

• Complex strictures, tumors, or infections: Longer duration due to additional diagnostic or therapeutic steps.

3. Additional Procedures Performed

• Stone removal: Adding balloon extraction or lithotripsy increases time.

• Biopsies: Collecting tissue samples for diagnosis takes extra minutes.

• Dilation: If strictures need dilation before stent placement, this adds time.

4. Patient Factors

• Anatomical challenges: Variations in bile duct anatomy or post-surgical alterations (e.g., gastric bypass) can prolong the procedure.

• Complications during the procedure: Difficulty accessing the bile duct or dealing with bleeding or perforation can extend the time.

5. Experience of the Endoscopist

• Skilled and experienced gastroenterologists often complete the procedure more efficiently.

Preparation and Recovery Time

• Preparation time: Additional 30–60 minutes for sedation and positioning.

• Recovery time: After the procedure, patients are monitored in a recovery area for 1–2 hours before discharge (if done on an outpatient basis).

Conclusion

The actual procedure for an ERCP with stent insertion typically lasts 30–120 minutes, depending on complexity. Including preparation and recovery, the total time spent in the facility may be 3–5 hours.
