Abstract
Endoscopic ultrasound/endosonography-guided pancreaticogastrostomy (EUS-PGS) is a useful alternative when endoscopic retrograde pancreatography is difficult. Recently, many procedures, including peroral pancreatoscopy (POPS), have been performed through the mature fistula (MF) created by EUS-PGS. We evaluate the efficacy and safety of POPS to diagnose and treat pancreatic ductal stricture/pancreato-jejunal anastomotic stricture (PDS/PJAS) through the MF. Twenty patients underwent EUS-PGS; 13 of these underwent POPS through the MF at Juntendo University Hospital. All patients were studied retrospectively in terms of technical and clinical success rates and adverse events (AEs). The technical and clinical success rates of EUS-PGS were 95% and 100%. The early and late AEs rates were 20% and 15%. The technical success rate of POPS was 100%, with one AE. Biopsy of PDS/PJAS under POPS guidance revealed recurrent/residual intrapapillary mucinous adenoma (3 patients) and benign fibrotic stricture (10 patients). In the latter patients, multiple plastic stents were placed to dilate PDS/PJAS. Four patients with improvement of PDS/PJAS were stent free, but the remaining patients were not yet. Endoscopic ultrasound/endosonography-guided pancreaticogastrostomy and various procedures (including POPS) performed through the MF are feasible and effective and can diagnose and treat PDS/PJAS with acceptable AEs rates.
