failure of gastric anastomoses. This study examines the degree of revascularization of the gastric fundus following BAE. Materials and Methods: The selection of fundal arteries for BAE was based on a celiac DSA C-arm CT (Siemens Artis Zee). From the celiac axis, fundal arteries were targeted, and an anti reflux microcatheter (Surefire mT) and 0.016-inch steerable guidewire were inserted. In five pigs, X-ray visible 50-micron BaSO 4 alginate-impregnated microbeads (XEB) were infused (BAE) with repeat angiography performed at one month. In two pigs, 300-500-micron Embospheres were infused (BAE) with repeat angiography performed at four months. All arteries were initially embolized to complete stasis. Angiograms were reviewed independently by two experienced interventional radiologists (CW, BH) and scored for degree of recanalization (yes/no/partial) or collateralization (yes/no). Results: Of the 11 arteries embolized with 50-micron XEB, seven demonstrated complete recanalization, three demonstrated partial recanalization, and one demonstrated collateralization at one month. Of the four arteries embolized with 300-500 micron Embospheres, three demonstrated complete recanalization, and one demonstrated collateralization at four months. Conclusion: Of the 15 arteries embolized, all demonstrated either complete or partial revascularization or robust collateralization. This provides preliminary data that following BAE, the gastric fundus regains adequate perfusion. This should begin to mitigate concerns in the surgical community that gastric bypass following BAE would be contraindicated. 4:33 PM Abstract No. 223Use of celiac angiography immediately after percutaneous transhepatic portal interventional radiological procedure to confirm injury of the hepatic artery

Objective: to determine the long term risk of hysterectomy following balloon endometrial ablation. Design: retrospective cohort study. Setting: A teaching university NHS hospital(Queen Elizabeth The Queen Mother Hospital. Methods: Patients having balloon endometrial ablation were prospectively recorded in an operating room log-book between 2001 to 2016. This logbook was used to search the pathology laboratory database (Dart and Apex) to identify patients who required a hysterectomy. Results: 796 patients underwent BEA at QEQM Hospital in Margate. The patients’ age was between 25 to 60 years. A hysterectomy was subsequently performed in 166 women (20.85%). The risk of hysterectomy was higher among the 40-50 age group. The shortest time to hysterectomy was 1 year and the longest was 10 years. Conclusion: The risk of having a hysterectomy after endometrial ablation in this study was 8.7% in the first year after the ablation and this risks drop to 3.5% in 2 years after the ablation. There was 20.85% failure rate of endometrial ablation using thermachoice, and this raise the question about the effectiveness of other devices which use ballon ablation like thermablate, cavaterm and librata.
