Methods: This prospective study was conducted in Endoscopy Suite, Surgical Unit IV, Civil Hospital Karachi from April, 2021 to January, 2022 for a period of 10 months. Patients undergoing ERCP for inoperable malignant biliary obstruction were randomized into EST group and non EST group. Stent patency was the primary end point.

Results: Total number of patients was 83. Out of which 48 patients were in EST group and 35 in non EST group. 55 pts were male and 28 were female with a mean age of 64.2 ± 7.2 yrs. Stent patency was higher in non EST group (74.28% vs 68% P < 0.05). There was no significant difference in other complications between the two groups.

Conclusion: In our study stent patency was significantly higher in non EST group.
