Background: The aim of this study was to analyze the efficiency and safety of the bipolar tissue/vessel sealing and cutting device EnSeal(™) in comparison to the conventional clamp and ligation technique in visceral surgery.
Material And Methods: In an acute animal model, a part of the small bowel, a part of the colon and the kidneys were resected either with the conventional clamp and ligation technique or with EnSeal(™). Operation time, blood loss and blood parameters as well as the lateral thermal spread were evaluated.
Results: Small bowel, colon and kidney resection time with the EnSeal(™) device was shorter compared to the conventional clamp and ligation technique (small bowel: EnSeal(™): 4.7 ± 1.0 min vs. con: 35.1 ± 2.3 min; colon: EnSeal(™): 7.0 ± 1.4 min vs. con: 16.3 ± 1.5 min, kidney: EnSeal(™): 5.7 ± 1.3 min vs. con: 16.7 ± 3.7 min, p < 0.05) and blood loss was significantly lower. Blood analysis demonstrated no differences in both groups. The lateral thermal spread was not more than 1 mm with EnSeal(™).
Conclusion: The bipolar sealing in visceral surgery with EnSeal(™) can be performed more efficiently in a shorter time, with significantly less blood loss, minimal thermal damage and without changes of blood parameters, indicating biological safety and integrity.

Department of Cardiothoracic Surgery, Lankenau Heart Institute, Wynnewood, PA, USA.
Purpose: Research on the safety and efficacy of del Nido cardioplegia in adult patients with reduced left ventricular ejection fraction (LVEF) is limited. We evaluated the effect of del Nido cardioplegia on early outcomes of cardiac surgery in this cohort.
Methods: PubMed, Scopus, and the Cochrane Central Register of Controlled Trials were searched through August 2024 to conduct a meta-analysis comparing del Nido to other cardioplegia in adult patients with reduced LVEF (≤50%).
Midterm Results of Fenestrated Frozen Elephant Trunk Technique for Acute Type A Aortic Dissection.
Ann Thorac Surg Short Rep
June 2024
Department of Cardiovascular Surgery, Fukushima Medical University, Fukushima, Japan.
Background: There is limited experience and knowledge of the use of the fenestrated frozen elephant trunk (FET) technique in acute type A aortic dissection (ATAAD). This study's aims were to assess the clinical outcomes of the fenestrated FET technique for ATAAD and to identify its best practices and pitfalls.
Methods: This study included 101 patients who underwent emergency surgical aortic repair for ATAAD at our hospital between October 2018 and April 2023.
Benefit of minimally invasive extracorporeal circulation on minimally invasive aortic valve replacement through right lateral mini-thoracotomy using femoral cannulation: a propensity-matched analysis.

Department of Cardiovascular Surgery, Kitasato University Hospital, Sagamihara, Kanagawa, Japan.
Objectives: The objective of this study was to evaluate the impact of minimally invasive extracorporeal circulation on blood transfusion and asymptomatic brain injury in comparison to conventional extracorporeal circulation in the context of minimally invasive aortic valve replacement through right lateral mini-thoracotomy surgery.
Methods: This was a retrospective observational study. Patients who underwent isolated aortic valve replacement through right lateral mini-thoracotomy surgery were divided into two groups: the minimally invasive extracorporeal circulation group and the conventional extracorporeal circulation group.
Efficacy and Safety of a Novel Tapered-Tip Sheath System for Biliary-Lesion Tissue Sampling: A Randomized Controlled Trial.
Gut Liver

Department of Gastroenterology and Hepatology, Graduate School of Medicine, Kyoto University, Kyoto, Japan.
Background/aims: Pathological evaluation is crucial for diagnosing biliary lesions and determining appropriate treatment strategies. However, tissue sampling via the transpapillary route can be difficult. In this study, we aimed to assess the efficacy and safety of a novel tapered-tip sheath system for tissue sampling from biliary strictures.
