Twelve-Month Follow-Up on 60 Consecutive Cases of Ultrasound-Guided Laparoscopic Radiofrequency Ablation of Symptomatic Fibroids

Abstract Background Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) has been increasingly used for the management of various solid pancreatic tumors. This study aimed to evaluate the feasibility and safety of EUS-RFA for serous cystic neoplasms (SCNs). Methods 13 patients with microcystic SCNs with honeycomb appearance underwent EUS-RFA using a 19-gauge RFA needle. Before ablation, cystic fluid was aspirated until a thin layer of fluid remained. Results EUS-RFA was successful in all patients. Seven patients underwent a single session and the remaining six patients underwent a second session of EUS-RFA. One patient (7.7 %) experienced self-limited abdominal pain after EUS-RFA. During a median follow-up period of 9.21 months (interquartile range [IQR] 5.93 – 15.38), the median volume of the SCNs decreased from 37.82 mL (IQR 15.03 – 59.53) at baseline to 10.95 mL (IQR 4.79 – 32.39) at the end of follow-up. A radiologic partial response was achieved in eight patients (61.5 %). Conclusions EUS-RFA is technically feasible and showed an acceptable rate of adverse events for patients with SCNs. A long-term follow-up study is required to evaluate the efficacy of EUS-RFA.

SummaryTo evaluate and compare the fiveyear outcome after treatment of a varicose GSV by endovenous thermal laser ablation (EVLA) and radiofrequency ablation (RFA).In this non-randomized, prospective study, patients treated in 2007 and 2008 for complete varicosis of the GSV (CEAP: C2–C6) were divided according to the treatment technique used into three groups: RFA (VNUS ClosureFast™), EVLA 980 nm (ELVeS 980™) and EVLA 1470 nm (ELVeS 1470™). Ultrasound-guided follow-up consultations were conducted 3 days, 3 months, 1 year and 5 years after treatment.589 patients with 643 GSVs (223 RFA, 185 EVLA 980, 235 EVLA 1470) were treated under tumescent local anaesthesia. No major complications occurred and minor complications were rare (4.7–12.2 %, p=0.135).66 % (RFA), 15 % (EVLA 980) and 32 % (EVLA 1470) of the patients were pain-free without post-operative analgesics. After 5 years, 86 % (RFA), 90 % (EVLA 980) and 93 % (EVLA 1470) of the veins were occluded (p=0.096). Ultrasound imaging revealed reflux in treated GSVs in 5–8 % of cases (p=0.73). A second ablation of the previously treated GSV was required in 5 % (RFA), 2 % (EVLA 980) and 2 % (EVLA 1470) of the patients (p=0.28).Endoluminal thermal ablation is an easy, safe and well tolerated method for the treatment of varicosis. Radiofrequency ablation is less painful than EVLA. RFA and EVLA 1470 are equally effective for vein closure.

Background. Percutaneous radiofrequency ablation (RFA) is a minimally invasive method of treatment based on thermal effects. This retrospective study aimed to clarify percutaneous RFA of kidney tumors – performance, extremeness and 5-year survival in patients with small renal tumors in a single center. Materials and methods. Between September 2003 and December 2012, a total of 118 patients underwent percutaneous RFA of renal tumors. During more than 9 years period 144 RFA procedures were performed. Tumors were verified by biopsy. We used 3 RFA techniques: RFA under ultrasound control only (US), ultrasound guided RFA with CT navigation (US/CT) and ultrasound guided RFA with CT navigation, fiducial markers placed around the kidney tumor before the treatment (US/CT/FM). RFA electrodes were one and three. Patients were followed up regularly by CT with contrast enhancement. Results. The mean patient age was 68.72 years (range 28 to 86). The mean tumor size was 2.8 cm (range 1 to 5.4). The mean follow-up time was 29 months (1–111 months). Radical dependence on technical procedures: only US 39 (66.1%), US/CT 18 (94.7%), US/CT/FM 37 (92.5%), p = 0.001. Radical differences between using one and three electrodes: 39 (66.1%) and 55 (93.2%), p

Objective: To evaluate the hemostatic efficacy of re-radiofrequency ablation (re-RFA) for hepatic tract bleeding after ultrasound-guided RFA of hepatic tumors. Methods: A total of 4679 percutaneous ultrasound-guided RFA procedures were performed for hepatic tumors at Samsung Medical Center between January 2012 and December 2020. We identified patients who had hepatic tract bleeding after RFA by reviewing radiologic reports and ultrasound images and investigated the measures taken to control the bleeding and their outcomes. We also identified patients who had a significant peritoneal hematoma on immediate post-RFA CT or underwent transarterial embolization to control hepatic bleeding after RFA of hepatic tumors. Results: In total, 91 patients with tract bleeding after RFA were identified. As initial measures to control the bleeding, external compression, re-RFA, and observation were performed in 71 (78%), 17 (19%), and 3 (3%) patients, respectively. Hemostasis using re-RFA was attempted to control tract bleeding in 40 patients as an initial measure or an additional measure after other initial efforts. In all 40 patients, the bleeding stopped after re-RFA on Doppler ultrasound, and there was no active bleeding on the immediate follow-up CT. During the study period, in the years when re-RFA was performed frequently, the number of transarterial embolizations to control tract bleeding and significant peritoneal hematoma formation tended to be low. Conclusion: Hemostasis using re-RFA of the needle tract is effective in controlling tract bleeding after ultrasound-guided RFA of hepatic tumors. Advances in knowledge: Re-RFA is a simple, safe, and effective method to control tract bleeding.
