About

Endoscopic implantation of plastic or covered metal stents is widely used in a variety of benign pancreaticobiliary diseases, including duct stricture, large or difficult stones, bile or pancreatic juice leak, etc. There are some late-stage adverse events after stent insertion, such as stent occlusion, proximal or distal migration, secondary duct injury and failure of stent removal, etc. The longer the stents were inserted, more likely the adverse events would happen.

Although the optimal time of stent placement has not been well established, it has been recommended that plastic stent should be removed/exchanged within 3-4 months and covered metal stent be removed within 6 months. However, it was not uncommon that patients with stent implantation did not follow the recommendation of further stent management by endoscopists.

Many methods have been used to improve the adherence of patients in medical service. With the advance of mobile technology and popular use of mobile phones, it was believed that the patient-centered outcome could be improved by mobile telecommunication with the timely support of a patient by a health professional. Thus we hypothesize that mobile technology, reminding the patients the necessity of stent management in time by short message service (SMS), might increase the patient adherence in patients with benign pancreaticobiliary diseases after ERCP.
