Use of the full-thickness resection device (FTRD) to prevent bleeding after colonic polypectomy in a patient with a left ventricular assist device.

ABSTRACT: Background and study aims Treatment of colorectal polyps in patients undergoing permanent anticoagulation is associated with a significantly increased risk of peri-interventional bleeding. This specifically applies to polyps > 1 cm where endoscopic full-thickness resection (EFTR) with the full-thickness-resection device (FTRD) can be taken into consideration as an alternative approach to classical snare polypectomy. For these indications, EFTR appears to be superior to conventional techniques especially in terms of sufficient hemostasis due to the mechanical tissue compression achieved by the FTRD's integrated Over-The-Scope Clip (OTSC). This is demonstrated in the following case report of a 59-year-old male with a left ventricular assist device (LVAD) implanted due to congestive heart failure. He presented with intermittent hemorrhage from a large polyp in the ascending colon that was successfully treated via EFTR with the FTRD. A video is included.

Project description:AimsTherapy with phosphodiesterase-5 inhibitors (PDE5Is) after left ventricular assist device (LVAD) implantation has been associated with lower mortality and device thrombosis but increased risk for post-operative and gastrointestinal bleeding. We aimed to evaluate the impact of long-term PDE5Is on the overall bleeding risk after LVAD implantation.Methods and resultsWe retrospectively included patients who received a continuous-flow LVAD at our site and were prescribed with long-term oral PDE5Is after discharge from the index hospitalization. The primary endpoint was the occurrence of bleeding at 12 month follow-up. Secondary endpoints were all-cause death and the combination of bleeding and all-cause death. Our analysis included 109 patients of whom 75 (69%) received long-term PDE5Is. Mean age was 56 years, and 85% were male. At 12 months, 19 (17%) patients experienced at least one bleeding event. Patients on PDE5Is had higher bleeding rates (23% vs. 6%, P = 0.03) and more bleeding events per patient-year (0.32 vs. 0.06, P = 0.03) compared with patients not on PDE5Is. While overall bleeding incidence was excessively higher in the PDE5I group, there were no significant differences in the incidence of major bleeding (19% vs. 6%, P = 0.08) and gastrointestinal bleeding (11% vs. 3%, P = 0.18). Kaplan-Meier analysis revealed higher cumulative incidence of bleeding for the PDE5I group (log rank = 0.04) with no difference on all-cause death (log rank = 0.67) and the combination of bleeding and all-cause death (log rank = 0.13). Hospitalizations for bleeding and their duration were numerically higher in the PDE5I group (0.28 vs. 0.03, P = 0.07 and 2.4 vs. 0.2, P = 0.07, respectively).ConclusionsPhosphodiesterase-5 inhibitor treatment after LVAD implantation is associated with increased bleeding risk after LVAD implantation. The safety of long-term PDE5Is in LVAD patients remains unclear and needs to be further clarified in prospective studies with randomized study design.
