ABSTRACT

Background and study aims Endoscopic sphincterotomy plus large-balloon dilation (ES-LBD) has been reported as an alternative to endoscopic sphincterotomy for the removal of bile duct stones. This multicenter study compared complete endoscopic sphincterotomy with vs. without large-balloon dilation for the removal of large bile duct stones. This is the first randomized multicenter study to evaluate these procedures in patients with exclusively large common bile duct (CBD) stones. Methods Between 2010 and 2015, 150 patients with one or more common bile duct stones ≥ 13 mm were randomized to two groups: 73 without balloon dilation (conventional group), 77 with balloon dilation (ES-LBD group). Mechanical lithotripsy was subsequently performed only if the stones were too large for removal through the papilla. Endoscopic sphincterotomy was complete in both groups. Patients could switch to ES-LBD if the conventional procedure failed. Results There was no between-group difference in number and size of stones. CBD stone clearance was achieved in 74.0 % of patients in the conventional group and 96.1 % of patients in the ES-LBD group (P < 0.001). Mechanical lithotripsy was needed significantly more often in the conventional group (35.6 % vs. 3.9 %; P < 0.001). There was no difference in terms of morbidity (9.3 % in the conventional group vs. 8.1 % in the ES-LBD group; P = 0.82). The cost and procedure time were not significantly different between the groups overall, but became significantly higher for patients in the conventional group who underwent mechanical lithotripsy. The conventional procedure failed in 19 patients, 15 of whom underwent a rescue ES-LBD procedure that successfully cleared all stones. Conclusions Complete endoscopic sphincterotomy with large-balloon dilation for the removal of large CBD stones has similar safety but superior efficiency to conventional treatment, and should be considered as the first-line step in the treatment of large bile duct stones and in rescue treatment.Trial registered at ClinicalTrials.gov (NCT02592811).

ABSTRACT

Background and study aims: The hemostatic powder TC-325 (Hemospray; Cook Medical, Winston-Salem, North Carolina, USA) has shown promising results in the treatment of upper gastrointestinal bleeding (UGIB) in expert centers in pilot studies. The aim of this study was to evaluate the feasibility and efficacy of TC-325 in a large prospective registry of use in routine practice. Patients and methods: The data of all patients treated with TC-325 were prospectively collected through a national registry. Outcomes were the immediate feasibility and efficacy of TC-325 application, as well as the rates of rebleeding at Day 8 and Day 30. Multivariate analysis was performed to determine predictive factors of rebleeding. Results: A total of 202 patients were enrolled and 64 endoscopists participated from 20 centers. TC-325 was used as salvage therapy in 108 patients (53.5 %). The etiology of bleeding was an ulcer in 75 patients (37.1 %), tumor in 61 (30.2 %), postendoscopic therapy in 35 (17.3 %), or other in 31 (15.3 %). Application of the hemostatic powder was found to be very easy or easy in 31.7 % and 55.4 %, respectively. The immediate efficacy rate was 96.5 %. Recurrence of UGIB was noted at Day 8 and Day 30 in 26.7 % and 33.5 %, respectively. Predictive factors of recurrence at Day 8 were melena at initial presentation and use of TC-325 as salvage therapy. Conclusion: These multicenter data confirmed the high rate of immediate hemostasis, excellent feasibility, and good safety profile of TC-325, which could become the treatment of choice in bleeding tumors or postendoscopic bleeding but not in bleeding ulcers where randomized studies are needed. TRIAL REGISTRATION: ClinicalTrials.gov (NCT02595853).
