Abstract
【Background】 There is limited evidence demonstrating the usefulness of endoscopic retrograde pancreatic drainage (ERPD) for symptomatic pancreaticojejunal anastomotic stenosis (sPJS). We examined the usefulness of ERPD for sPJS. 【Methods】 We conducted a retrospective analysis of 10 benign sPJS patients. Following items were evaluated: technical success, adverse events and clinical outcome of ERPD. 【Results】 Technical success rate was 100% (10/10); 9 patients had a pancreatic stent (no-internal-flap: n=4, internal-flap: n=5). Median follow-up was 920 days. Four patients developed recurrence. Among them, 3 patients had a stent with no-internal-flap in initial ERPD and the stent migrated in 3 patients at recurrence, and a stent was not placed in 1 patient in initial ERPD. Four follow-up ERPD were performed. No recurrence was observed in 6 patients. Among them, none of the stents migrated (no-internal-flap: n=1, internal-flap: n=5), and none were replaced stents due to stent failure. A stent placement with no-internal-flap was associated with recurrence (p=0.042). Mild adverse events developed in 14.3% (2/14). 【Conclusions】 ERPD was performed safely with high technical success. Recurrence was common in a stent placement with no-internal-flap, which was associated with stent migration. Long-term stent placement didn’t result in stent failure.
