Abstract:
Objective To study the technique of double stent drainage on biliary and pancreatic ducts obstruction,and to assess its clinical effectiveness.Methods Firstly,ERCP was done on all patients to investigate the locus and extent of the stricture or obstruction,in order to choice the stent with suitable diameter and length.Then the stents placed into biliary and pancreatic ducts though the guidewires those was inserted into the ducts already.After the operation,the level of serum amylase and clinical symptoms such as jaundice,abdominal pain and diarrhea were observed to assess the therapeutic effect.Results 14 patients diagnosed as biliary and pancreatic ducts stricture or obstruction were treated successfully with this method(5 patients suffered from ampulla cancer,4 carcinoma of head of pancreas,3 carcinoma of duodenum papilla,2 chronic inflammation of head of pancreas).Thirteen patients were placed with 14 plastic biliary stents in their biliary ducts(each was placed with one stent except one with 2 stents),and one patient was placed with metal stent.At the same time,14 pancreatic stents were placed into pancreatic ducts of these patients.The rate of jaundice extinction in 2 weeks,1 month and 3 months after the operation was 50 percent,71 percent and 93 percent respectively.The rate of abdominal pain remission in 2 weeks after operation was 75 percent.Among 7 diarrhea patients ,the clinical symptoms disappeared in 5 patients and were significantly improved in 2 patients one month after the operation.The obstruction and displacement of stents had not been observed in all patients within 3 months after the operation.The complications related to operation had not been observed in all patients within 3 months after the operation.Conclusions The therapy with double stent drainage in biliary and pancreatic duct stricture is safe and effective.It can relieve jaundice and abdominal pain,decrease biliary pressure and improve the exocrine dysfunction of pancreas.
