Hydrogen peroxide is a liquid that functions in mechanical removal of the necrotic tissue via the elimination of tissue debris. In this study, we aimed to evaluate the effectiveness of the use of hydrogen peroxide in necrosectomy treatment of walled-off pancreatic necrosis. Records of 24 patients who were diagnosed with pancreatic necrosis or walled-off pancreatic necrosis and underwent endoscopic necrosectomy (EN) were retrospectively assessed. Patients were divided into 2 groups; hydrogen peroxide used for treatment or not used, and these 2 groups were compared. A total of 24 patients underwent endoscopic intervention for walled-off pancreatic necrosis. Procedural success was comparable between the 2 groups. During the post-procedural follow-up, the duration of the hospital stay, recurrence, and complication rates were found to be similar in both groups. The mean number of the endoscopic interventions was significantly lower in the hydrogen peroxide group (4.2 ± 1.4 vs 6.1 ± 4.2; P = .01). The use of hydrogen peroxide for EN in walled-off pancreatic necrosis patients seems to have similar efficiency and safety. However, it can be said that the use of hydrogen peroxide could reduce the number of endoscopic procedures.

Türkiye'de sanayinin gelişmesi ve yaygınlaşması için enerjiye gereksinim vardır. Bu nedenle enerji üretiminin artırılması, enerjiden tasarruf sağlanması ve binaların yalıtımına önem verilmesi, atık maddelerin değerlendirilmesi gibi konuların önemi giderek artmaktadır. 2019 yılı verilerine göre Türkiye'de elektriğin yaklaşık %57,8'i fosil yakıtlardan üretilmektedir. Fosil yakıtların yaklaşık %65'ini kömür oluşturmaktadır. Kahramanmaraş Afşin-Elbistan Termik Santrali, linyit kömürü ile elektrik üreten santrallerden biridir. Afşin-Elbistan Termik Santrali'nde yılda yaklaşık iki milyon ton uçucu kül üretilmekte ve bu külün çok azı kullanılmaktadır. Bu uçucu külün yeterince kullanılmamasının nedeni; kimyasal yapısının standartların öngördüğü kriterlere uygun olmamasıdır. Atık külün depolama sorunu yanında, çevrenin kirlenmesine önemli derecede etkisi de bulunmaktadır. Diğer yandan endüstriye kazandırılması halinde ülke ekonomisine önemli oranda katkı sağlaması bilinen bir gerçektir. Bu deneysel çalışmada, Kayseri bimsi, cam atığı tozu, az oranda kolemanit ilaveleriyle Afşin-Elbistan Termik Santrali uçucu külü (AEUK) standarda uygun hale getirilmiştir. Basınç dayanımı, priz süresi, hacimsel genleşme, donma-çözülme gibi deneyler yapılmıştır. Katkı maddeleri sayesinde, AEUK'nın betonda kullanılabileceği ortaya çıkarılmıştır.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
