Event Description

Olympus reviewed the following literature article: "endoscopic ultrasound-guided drainage of patients with infected walled-off necrosis: which stent to choose?" literature summary: this single-center retrospective study of a prospectively collected database of all symptomatic pancreatic fluid collection (pfc) patients who underwent eus-guided drainage.Among 120 patients with pfc (108 walled-off necrosis (won), 22 pseudocyst) who underwent eus-guided drainage, there was no difference in outcome parameters in biflanged metal stents (bfms) and double pigtail plastic stents (dpps) groups.Among patients with won, clinical success was significantly higher (96.2% vs.81.8%, p=0.04), with significantly shorter hospital stay (6 vs.10 d) and procedure duration (17.18 ± 4.6 vs.43.6 ± 9.7 min, p<.0001) in the bfms group.Among patients with infected won with/without organ failure (of), the clinical success was significantly higher (100% vs.73.9%) in bfms compared with dpps group.The duration of the procedure was significantly lower (16.28 ± 4.4 vs.44.39 ± 10.7, p<.0001) in bfms compared with dpps group this study concluded that eus-guided drainage of won using bfms scores over dpps.In patients having infected won with/without of, bfms may be preferred over dpps.Type of adverse events/number of patients: [dpps] (n = 60), bleed - 4 patients, perforation - 1 patient, stent migration - 1 patient, recurrence of collection - 2 patients, mortality - 2 patients.[bfms] (n = 60), bleed - 1 patient, stent migration - 2 patients, recurrence of collection - 1 patient.For the "ez shot3 plus" described in the literature, we selected the "na-u200h-8019" with the largest number of shipments in the region and during the study period, and created etq.Since there is no olympus device called "uct 180", "gf-uct180" was selected.From the above, 6 complaints were created because the literature includes patient deaths.(b)(6): na-u200h-8019(for death of patients).(b)(6): na-u200h-8019(for adverse events other than death).(b)(6): gf-uct180 (for death of patients).(b)(6): gf-uct180 (for adverse events other than death).(b)(6): gif-hq190 (for death of patients).(b)(6): gif-hq190 (for adverse events other than death).This complaint is (b)(6).
