A clinically-oriented computer model for radiofrequency ablation of hepatic tissue with internally cooled wet electrode

Ewertowska, Elzbieta; Quesada-Diez, Rita; Radosevic, A.; Andaluz, Anna; Moll, Xavier; García Arnás, F.; Berjano, Enrique; Burdío Pinilla, Fernando; Trujillo Guillen, Macarena (Taylor & Francis, 2019)

[EN] Purpose: To improve the computer modelling of radiofrequency ablation (RFA) by internally cooled wet (ICW) electrodes with added clinically oriented features. Methods: An improved RFA computer model by ICW electrode ...
Can electroporation previous to radiofrequency hepatic ablation enlarge thermal lesion size? A feasibility study based on theoretical modelling and in vivo experiments

Trujillo Guillen, Macarena; Castellvi, Quim; Burdío, Fernando; Sánchez Velázquez, Patricia; Ivorra, Antoni; Andaluz, Anna; Berjano, Enrique (Informa Healthcare, 2013-05)

Purpose: The aim of this study was to assess the feasibility of a hybrid ablative technique based on applying electroporation (EP) pulses just before conducting radiofrequency ablation (RFA). The rationale was that the ...
Could the heat sink effect of blood flow inside large vessels protect the vessel wall from thermal damage during RF-assisted surgical resection?

González Suárez, Ana; Trujillo Guillen, Macarena; Burdío, Fernando; Andaluz, Anna; Berjano, Enrique (American Association of Physicists in Medicine: Medical Physics, 2014-08)

Purpose: To assess by means of computer simulations whether the heat sink effect inside a large vessel (portal vein) could protect the vessel wall from thermal damage close to an internally cooled electrode during ...
Development of a catheter-based technique for endoluminal radiofrequency sealing of pancreatic duct

Ewertowska, Elzbieta; Andaluz, Anna; Moll, Xavier; Adrià Aguilar; Garcia, Felix; Fondevila, Dolors; Quesada, Rita; Trujillo Guillen, Macarena; Burdio, Fernando; Berjano, Enrique (Taylor & Francis, 2019-01-01)

[EN] Introduction: Endoluminal sealing of the pancreatic duct by glue or sutures facilitates the management of the pancreatic stump. Our objective was to develop a catheter-based alternative for endoluminal radiofrequency ...
Endoluminal radiofrequency ablation of the main pancreatic duct is a secure and effective method to produce pancreatic atrophy and to achieve stump closure

Andaluz, Anna; Ewertowska, Elzbieta; Moll, Xavier; Aguilar, Adrià; García, Félix; Fondevila, Dolors; Quesada, Rita; Berjano, Enrique; Grande, Luís; Burdío, Fernando (Nature Publishing Group, 2019)

[EN] Radiofrequency energy has been used both experimentally and clinically to manage the pancreatic remnant after distal pancreatectomies. Our goal was to determine whether endoluminal radiofrequency (RF) ablation of the ...
Laparoscopic Distal Pancreatectomy: Feasibility Study of Radiofrequency-Assisted Transection in a Porcine Model

Dorcaratto, Dimitri; Burdio Pinilla, Fernando; Fondevila, Dolors; Andaluz, Anna; Poves, Ignasi; Martínez, María Ángeles; Quesada, Rita; Berjano Zanón, Enrique; Grande, Luis (Mary Ann Liebert, 2012)

Background and Aim: Despite technological improvements in pancreatic surgery, the incidence and morbidity of pancreatic leak after resection of distal pancreas are persistently high in most series. Laparoscopic distal ...
Radiofrequency is a secure and effective method for pancreatic transection in laparoscopic distal pancreatectomy: results of a randomized, controlled trial in an experimental model

Dorcaratto, Dimitri; Burdío, Fernando; Fondevila, Dolors; Andaluz, Anna; Quesada, Rita; Poves, Ignasi; Cáceres, Marta; Mayol, Xavi; Berjano, Enrique; Grande, Luis (Springer-Verlag, 2013)

[EN] Postoperative pancreatic fistula (PPF) is the most frequent and serious complication after laparoscopic distal pancreatectomy (LDP). Our goal was to compare the performance, in terms of PPF prevention, and safety of ...
Radiofrequency-induced heating versus mechanical stapler for pancreatic stump closure: in vivo comparative study

Burdío Pinilla, Fernando; Dorcaratto, dimitri; Hernandez, Lourdes; Andaluz, Anna; Moll, Xavier; Quesada-Diez, Rita; Poves, Ignasi; Grande, Luís; Cáceres, Marta; Berjano, Enrique (Taylor & Francis, 2016)

Purpose: To assess the capacity of two methods of surgical pancreatic stump closure in terms of reducing the risk of pancreatic fistula formation (POPF): radiofrequencyinduced heating versus mechanical stapler. Materials ...
