Abstract:
Objective To assess the safety and the efficacy of endoscopic ultrasound (EUS)-guided transmural drainage of pancreatic pseudocysts (PPC).Methods A total of 17 patients with PPC who underwent EUS to detect the optimal site and depth of puncture.The needle was punctured into the PPC cavity through endoscopic biopsy hole,cyst fluid was drained with a syringe.The guide wire was inserted along the pinhole under X-ray,and then the needle-knife was sent along the guide wire to cut the gastric wall and pseudocysts wall,followed by balloon dilation.The way of drainage was selected according to the cyst fluid properties.The technical success rate,treatment success rate,complication occurring rate and the skills were evaluated.Results Four patients were with nasalcystic catheter drainage,9 patients with double pigtail stents internal drainage,and 4 patients with nasal-cystic catheter and double pigtail stents combination drainage.The treatment success rates were 3/4,7/9,and 4/4 respectively.Only 1 patient subsequently developed bleeding from puncture site after stent successively placed,and was turned to surgery because of ineffective endoscopic treatment.Infection occurred in 4 patients during drainage,two of those were switched to surgical resection due to poor medical treatment response,and the other 2 were cured with intravenous infusion of antibiotics sensitive to cyst fluid bacteria and metronidazole rinse PPC.The median follow-up duration was 28.5months,and there was none of recurrence.Conclusions EUS-guided transmural drainage of PPC is safe.Stent placement and nasal-cystic catheter play an important role in PPC treatment.
