Abstract
BACKGROUND AND STUDY AIMS: Endoscopic management using standard accessories is the preferred modality for treatment of benign biliary strictures. However, with difficult strictures, there is frequently failure of endoscopic therapy. We are reporting our experience regarding use of a standard diathermic dilator (cystotome) to aid in stricture dilatation and stent placement in patients with difficult strictures. PATIENTS AND METHODS: Data were analyzed from January 2014 to January 2017 at a single tertiary care center in North India. Total 25 patients were included. RESULTS: The mean age was 45 years (varying from 38 - 55 years). Of the 25 patients with difficult strictures, 14 (56 %) were male and 11 (44 %) were female. Further, of these, 19 had biliary and 6 had pancreatic strictures. The average time of diathermic current application was 3.5 seconds (ranging 3 - 5 seconds). Technical and clinical success were achieved in 100 % of cases. None of the patients had any procedure-related (early or delayed) major complications. CONCLUSION: The cystotome is an extremely safe and useful accessory in benign biliary and pancreatic strictures, whereas conventional methods to negotiate stricture have failed.
