Background: Endoscopic papillary large balloon dilation (EPLBD) without prior endoscopic sphincterotomy (EST) produces excellent outcomes for the treatment of large common bile duct (CBD) stones. However, it remains unclear how the outcomes of EPLBD alone compare with those of EPLBD with EST. In this study, we assessed the safety and therapeutic outcomes of EPLBD with vs. without EST for the removal of large bile duct stones.Methods: This prospective, multicenter study was conducted on 200 patients with bile duct stones of ≥ 10 mm in diameter. Patients were randomly assigned to an EPLBD alone group (n = 100) or an EPLBD with EST group (n = 100). These two groups were compared with respect to overall procedure-related adverse events, overall stone removal success rate, number of endoscopic sessions required for complete stone removal, need for mechanical lithotripsy, and total procedure time.Results: The incidence of adverse events was not significantly different between the groups (EPLBD alone vs. EPLBD with EST: overall adverse events 6 % vs. 4 %, P = 0.75; pancreatitis 1 % vs. 3 %, P = 0.62). Overall success (P = 0.35), initial success (P = 0.28), and the need for mechanical lithotripsy (P = 0.39) were also similar between groups. Median total procedure time tended to be greater in the EPLBD alone group (20.5 minutes) than in the EPLBD with EST group (18 minutes; P = 0.08).Conclusion: The therapeutic outcomes and adverse events of EPLBD alone for the removal of large bile duct stones were comparable to those of EPLBD with EST.

Background and Study Aim: Fully covered, self-expandable metal stents (FCSEMSs) are acceptable tools for treating benign biliary stricture (BBS). However, little is known about the long-term outcomes of this technique. The aim of the present study was to evaluate the procedural and long-term outcomes of FCSEMSs for treating BBSs.Patients and Methods: A total of 134 consecutive patients (median age 56 years; range 21 - 83) with BBS were retrospectively reviewed. The main outcomes were technical and clinical success, stricture resolution, recurrence, and adverse events. Outcomes were analyzed by reviewing patient medical records.Results: The success rates of FCSEMS placement and removal were 99.3 % and 98.2 %, respectively. Stricture resolution occurred in 103/132 (78.0 %) of the patients (median stent duration, 93 days; range 1 - 489). The associated factors for stricture resolution were longer stent indwelling period (≥ 120 days) and absence of stent migration. Stricture recurrence was seen in 26/103 patients (25.2 %; 95 % confidence interval [CI] 0.17 - 0.34) within a median of 390 days (range 4 - 903 days). Chronic pancreatitis was associated with stricture recurrence (hazard ratio [HR] 2.59, 95 %CI 1.20 - 5.61; P = 0.02). Stent migration occurred in 41/132 patients (31.1 %; 95 %CI 0.23 - 0.39). The FCSEMS with anchoring flaps appeared to protect against stent migration (HR 0.22, 95 %CI 0.08 - 0.63; P < 0.01).Conclusion: FCSEMSs had a high success rate for BBS resolution. Longer indwelling periods and the absence of stent migration might be important factors for stricture resolution. [ABSTRACT FROM AUTHOR]
