Good Success Rate

Nowadays endoscopic treatment of common bile duct stones is considered the treatment of choice for all common bile duct stones. Although this procedure is related to a good success rate, in rare cases serious complications can happen, especially if you use a Dormia basket. Here we describe the clinical case of a patient affected by hepatolithiasis, cholelithiasis, and common bile duct lithiasis with entrapment of a Dormia basket in the cystic duct. It was necessary to perform a surgical choledochotomy to deal with this rare complication.

Nonthermal Irreversible Electroporation

Background Esophageal ulceration and fistula are severe complications of pulmonary vein isolation using thermal ablation. Nonthermal irreversible electroporation (NTIRE) is a promising new technology for pulmonary vein isolation in patients with atrial fibrillation. NTIRE ablation technology has been used to treat atrial fibrillation; however, the effects of NTIRE on esophageal tissue have not been clearly described. Methods and Results A typical NTIRE electrical protocol was directly applied to esophagi in 84 New Zealand rabbits. Finite element modeling and histological analysis with 120 slices were used to analyze electric field intensity distribution and subsequent tissue changes. A parameter combination of 2000 V/cm multiplied by 90 pulses output is determined to be an effective ablation parameters combination. Within 16 weeks after ablation, no obvious lumen stenosis, epithelial erythema, erosion, ulcer, or fistula was observed in the esophageal tissue. NTIRE effectively results in esophageal cell ablation to death, and subsequently, signs of recovery gradually appear: creeping replacement and regeneration of epithelial basal cells, repair and regeneration of muscle cells, structural remodeling of the muscle layer, and finally the restoration of clear anatomical structures in all layers. Conclusions Monophasic, bipolar NTIRE delivered using plate electrodes in a novel esophageal injury model demonstrates no histopathologic changes to the esophagus at 16 weeks. Data of this study suggest that electroporation ablation is a safe modality for pulsed electroporation ablation near the esophagus.

Temperature Dynamic

Background: High-power short-duration (HP-SD) radiofrequency ablation (RFA) has been proposed as a method for producing rapid and effective lesions for pulmonary vein isolation. The underlying hypothesis assumes an increased resistive heating phase and decreased conductive heating phase, potentially reducing the risk for esophageal thermal injury. The objective of this study was to compare the esophageal temperature dynamic profile between HP-SD and moderate-power moderate-duration (MP-MD) RFA ablation strategies. Methods: In patients undergoing pulmonary vein isolation, RFA juxtaposed to the esophagus was delivered in an alternate sequence of HP-SD (50 W, 8–10 s) and MP-MD (25 W, 15–20 s) between adjacent applications (distance, ≤4 mm). Esophageal temperature was recorded using a multisensor probe (CIRCA S-CATH). Temperature data included magnitude of temperature rise, maximal temperature, time to maximal temperature, and time return to baseline. In swine, a similar experimental design compared the effect of HP-SD and MP-MD on patterns of esophageal injury. Results: In 20 patients (68.9±5.8 years old; 60% persistent atrial fibrillation), 55 paired HP-SD and MP-MD applications were analyzed. The esophageal temperature dynamic profile was similar between HP-SD and MP-MD ablation strategies. Specifically, the magnitude of temperature rise (2.1 °C [1.4–3] versus 2.0 °C [1.5–3]; P =0.22), maximal temperature (38.4 °C [37.8–39.3] versus 38.5 °C [37.9–39.4]; P =0.17), time to maximal temperature (24.9±7.5 versus 26.3±6.8 s; P =0.1), and time of temperature to return to baseline (110±23.2 versus 111±25.1 s; P =0.86) were similar between HP-SD and MP-MD ablation strategies. In 6 swine, esophageal injury was qualitatively similar between HP-SD and MP-MD strategies. Conclusions: Esophageal temperature dynamics are similar between HP-SD and MP-MD RFA strategies and result in comparable esophageal tissue injury. Therefore, when using a HP-SD RFA strategy, the shorter application duration should not prompt shorter intervals between applications.
