Clinical case report: endoluminal thermal ablation of main pancreatic duct for patients at high risk of postoperative pancreatic fistula after pancreaticoduodenectomy

Ielpo, Benedetto; Pueyo-Périz, Eva M.; Radosevic, Aleksandar; Andaluz, Anna; Berjano, Enrique; Grande, Luis; Sánchez-Velázquez, Patricia; Burdío, Fernando (Taylor & Francis, 2021-01-01)

[EN] Purpose Multiple attempts have been made to manage the pancreatic stump and the pancreatic duct in order to reduce the rate of postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy (PD), however ...
Comparison of two radiofrequency-based hemostatic devices: saline-linked bipolar vs. cooled-electrode monopolar

Moll, Xavier; Fondevila, Dolors; García-Arnás, Félix; Burdio, Fernando; Trujillo Guillen, Macarena; Irastorza, Ramiro M.; Berjano, Enrique; Andaluz, Anna (Taylor & Francis, 2022-12-31)

[EN] Purpose To characterize the coagulation zones created by two radiofrequency (RF)-based hemostatic devices: one comprised an internally cooled monopolar electrode and the other comprised externally irrigated bipolar ...
Computer modeling of an impedance-controlled pulsing protocol for RF tumor ablation with a cooled electrode

Trujillo Guillen, Macarena; Bon Corbín, José; Rivera Ortun, María José; Burdio, Fernando; Berjano, Enrique (Taylor & Francis, 2016)

[EN] Purpose: To develop computer models to mimic the impedance-controlled pulsing protocol implemented in radiofrequency (RF) generators used for clinical practice of radiofrequency ablation (RFA), and to assess the ...
Electrical-thermal analytical modeling of monopolar RF thermal ablation of biological tissues: determining the circumstances under which tissue temperature reaches a steady state

López Molina, Juan Antonio; Rivera Ortun, María José; Berjano, Enrique (American Institute of Mathematical Sciences (AIMS), 2016-04)

[EN] It has been suggested that during RF thermal ablation of biological tissue the thermal lesion could reach an equilibrium size after 1-2 minutes. Our objective was to determine under which circumstances of electrode ...
Fourier, hyperbolic and relativistic heat transfer equations: a comparative analytical study

López Molina, Juan Antonio; Rivera Ortun, María José; Berjano, Enrique (Royal Society, The, 2014-10-08)

[EN] Parabolic heat equation based on Fourier's theory (FHE), and hyperbolic heat equation (HHE), has been used to mathematically model the temperature distributions of biological tissue during thermal ablation. However, ...
How large is the periablational zone after radiofrequency and microwave ablation? Computer-based comparative study of two currently used clinical devices

Trujillo Guillen, Macarena; Prakash, Punit; Faridi, Pegah; Radosevic, Aleksandar; Curto, Sergio; Burdio, Fernando; Berjano, Enrique (Taylor & Francis, 2020-01-01)

[EN] Purpose To compare the size of the coagulation (CZ) and periablational (PZ) zones created with two commercially available devices in clinical use for radiofrequency (RFA) and microwave ablation (MWA), respectively. ...
Is occlusion of the main pancreatic duct by thermal ablation really safe? A surgical innovation assessed according to IDEAL recommendations

Moll, Xavier; Fondevila, Dolors; García Arnás, Felix; Pérez, Juan J; Ielpo, Benedetto; Sánchez-Velázquez, Patricia; Grande, Luis; Jaume, Sofia; Radosevic, Aleksandar; Barranco, Luis; Berjano, Enrique; Burdio, Fernando; Andaluz, Anna (Taylor & Francis, 2023-12-31)

[EN] Introduction Pre-clinical studies suggest that thermal ablation of the main pancreatic duct (TAMPD) is more recommendable than glue for reducing postoperative pancreatic fistula (POPF). Our aims were (1) to analyze ...
Thermal profile detection through high-sensitivity fiber optic chirped Bragg grating on microstructured PMMA fiber

Korganbayev, Sanzhar; Min, Rui; Jelbuldina, Madina; Hu, Xuehao; Caucheteur, Christophe; Bang, Ole; Ortega Tamarit, Beatriz; Marques, Carlos; Tosi, Daniele (Institute of Electrical and Electronics Engineers, 2018-10-15)

[EN] In this work, a linearly chirped fiber Bragg grating (CFBG) inscribed in a microstructured polymer optical fiber (mPOF) has been demonstrated for detecting temperature pro- files during thermal treatments. A CFBG of ...
