RESUMO
To evaluate the effect of endoscopic treatment of pancreatic ductal stones (PDS), 31 patients with PDS treated in our hospital from January 1998 to Octomber 2001 were analyzed retrospectively. PDS were successfully extracted in 10 patients by endoscopic papillotomy (EPT) or endoscopic pancreatic sphincterotomy (EPS). In 2 patients, one was treated with extracorporeal shock wave lithotripsy (ESWL) and endoscopic retrograde pancreatic drainage (ERPD), another with EPS and ESWL, the PDS were all disappeared in 6 months. Fourteen patients with pancreatic ductal stricture were treated with ERPD, and 4 with EPS+ERPD. However, 4 patients were subjected to operation for pancreatic carcinoma and recurrent symptom. Only one of them failed owing to severe pancreatic ductal stricture. The success rate of the procedure was 96 8%, and the remission rate of abdominal pain was 90% shortly after operation and 70 4% in the follow up interval. The body weight and pancreatic exocrine function were also improved. But the stent occlusion was found in 3 patients and their stents were changed. So endoscopic therapy such as EPS, ESWL, and ERPD are effective and safe methods in treatment of PDS.
