EUS-Guided Pancreatic Cyst Ablation: a Clinical and Technical Review
Purpose of Review
Pancreatic cystic lesions represent a growing public health dilemma, particularly as our population ages and cross-sectional imaging becomes more sensitive. Mucinous cysts carry a clinically significant risk of developing pancreatic cancer, which carries an extremely poor prognosis. Determining which cysts will develop cancer may be challenging, and surgical resection of the pancreas carries significant morbidity. The goal of this paper is to review the rationale for cyst ablation and discuss prior and current research on cyst ablation techniques and efficacy. Indications, contraindications, and factors related to optimal patient selection are outlined.
Recent Findings
Endoscopic ultrasound-guided chemoablation of pancreatic cysts has been performed in neoplastic cysts, with varying levels of efficacy. Safety concerns arose due to the risk of pancreatitis in alcohol-based treatments; however, the most recent data using a non-alcohol chemoablation cocktail suggests that ablation is effective without the need for alcohol, resulting in a significantly more favorable adverse event profile.
Summary
Endoscopic ultrasound-guided chemoablation of neoplastic pancreatic cysts is a promising, minimally invasive approach for treatment of cysts, with recent significant advances in safety and efficacy, suggesting that it should play a role in the treatment algorithm
Adaptability of Miscanthus Cultivars for Biomass Production
In 2016, miscanthus dry matter production (DM) averaged 8,890 lb DM/a and did not differ between the two cultivars in production at the Mound Valley Unit of the Southeast Agricultural Research Center. Total three-year production for the cultivars was also similar, averaging 35,050 lb/a
Ultrafast magnetophotoconductivity of semi-insulating gallium arsenide
The speed of opto-electronic switches is increased or decreased by the application of a magnetic field. This is achieved by inducing a carrier drift toward or away from the semiconductor surface, resulting in the enhancement or suppression of surface recombination. We establish that surface recombination plays a major role in determining the speed of the opto-electronic switch
Evaluation of Tall Fescue Cultivars
Spring 2015 yield was higher for ‘Ky 31 EF’ than for nine of the 19 other entries. Summer production of ‘PBU-B7’ was greater than for five lower-yielding entries. Total 2015 production was greater for ‘PBU-B1’ and Ky 31 EF than for seven other cultivars
Evaluation of Tall Fescue Cultivars
Spring 2016 yield of tall fescue was higher for ‘NFTF 1051’ than for 12 of the 19 other cultivar entries. Summer production of ‘PBU-B2’ was greater than summer production of the three lower-yielding entries. Fall production of ‘BarOptima PLUS E34’ was higher than that of 12 other cultivar entries, but total 2016 production was greater for PBU-B2, ‘PBU-B7’, and NFTF 1051 than for eight other cultivars
The Synthesis of 2, 4, 6, 8 - Tetraoxo - 1, 2, 3, 4, 6, 7, 8, 9 - octahydro-benzo (1, 2-d:-5, 4-d\u27) bis (1, 3) oxazine
This 29 page thesis examines the synthesis of the three ring heterocyclic system containing two dioxo-1, 3-oxazine rings
Forage Production of Sorghum Cultivars
Total production from three cuttings of eight hay-type sorghum entries was greater from ‘Sweet Sioux WMR,’ ‘Cadan 99B,’ and ‘Trudan Headless’ than from ‘SDH 2942BMR’ and ‘AS6402.’ A separate test of 15 forage sorghums was conducted to assess dry matter (DM) production and other characteristics. Yields of ‘SPX-28313’ and ‘1990’ exceeded yields of 11 other entries. Production of ‘SPX3952,’ ‘AF7102,’ and ‘Atlas’ was less than that of six of the higher-yielding entries. Sorghum production tests were also conducted at Ottawa and Hutchinson (see KAES Research Reports, Vol. 1, Issue 2, Kansas Field Research)
Seeded Bermudagrass Cultivar Evaluation
A year after seeding, the stand of ‘F.K.#1’ appeared better than stands of 10 of the other 13 seeded entries. By fall, 2014, stands of ‘KF-13A,’ ‘KF-13B,’ and ‘SWI-800’ along with ‘F.K.#1’ were better than stands of four of the other seeded entries. Late-summer production was higher for KF-13A and ‘Midland 99,’ the sprigged check, than for five of the other entries
