OBJECTIVES: To assess the feasibility of off-clamp laparoscopic partial nephrectomy using microwave scissors. METHODS: We performed transperitoneal laparoscopic partial nephrectomy, without hilar clamping or renorrhaphy, using only microwave scissors for renal resection in a porcine model. For each kidney, 2 types of procedures were performed: a middle pole resection excising an area of 2-cm diameter and approximately 1-cm depth and a lower pole resection at the level of the lower polar line...

Background. Single anastomotic surgeries can increase the risk of reflux, marginal ulceration, and gastrointestinal complications. Braun anastomosis prevents bile reflux after gastric resection and gastrojejunal anastomosis surgeries. The present pilot study evaluated Braun's efficacy in a single anastomosis sleeve ileal (SASI) bypass surgery. Methods. 28 patients with a history of SASI bypass surgery from October 2017 to September 2021 were included in the study. Patients were divided into 2 groups based on having Braun anastomosis to this surgical procedure; group A: underwent SASI bypass without Braun anastomosis; group B: underwent SASI bypass with Braun anastomosis...

BACKGROUND/NEED: Laparoscopic rectal cancer surgery (LRCS) has become a preferred approach for its minimal invasion and fast postoperative recovery. But it is challenging for the tumors of the middle and lower rectum, especially for overweight or obese patients. METHODOLOGY: We present a space expander of laparoscopic rectal cancer surgery, which is a simple tool to widen the perirectal space, as to facilitate the procedure of total mesorectal excision (TME) during the rectal cancer surgery...

INTRODUCTION: Metallic foreign bodies (mFB) are common following penetrating injuries in children. The mFB commonly occur in the head and neck region and extremity soft tissues. Removal may be indicated due to morbidity related to pain or migration. Extraction can be challenging to localize, often requiring wide exposure, and may be difficult to achieve in cosmetically sensitive areas. Different technological adjuncts have been used to facilitate foreign body removal including fluoroscopy, ultrasound, and more recently in adults, surgical magnets...

BACKGROUND: Acute cholangitis (AC) is a common emergency with a significant mortality risk. This study aimed to compare urgent, early, and late endoscopic retrograde cholangiopancreatography (ERCP) for AC. METHOD: We retrospectively evaluated patients diagnosed with AC from June 2016 to May 2021. According to the time of ERCP, patients were divided into urgent (≤24 h), early (24-48 h), and late (≥48 h) groups. Primary outcomes were technical success, in-hospital mortality, and 30-day mortality...

BACKGROUND: Computerized tomography (CT) is an integral part of the follow-up and decision-making process in complicated acute appendicitis (AA) treated non-operatively. However, repeated CT scans are costly and cause radiation exposure. Ultrasound-tomographic image fusion is a novel tool that integrates CT images to an Ultrasound (US) machine, thus allowing accurate assessment of the healing process compared to CT on presentation. In this study, we aimed to assess the feasibility of US-CT fusion as part of the management of appendicitis...

BACKGROUND: Laparoscopy revolutionizing digital and robotic technology for surgical practice. The ability of anesthetic agents and neuronal blockade to modify the response to surgical trauma has been widely studied in the last few years. OBJECTIVES: evaluate if Anterior Quadratus Lumborum Block contributes to attenuate surgical repercussions, having as primary parameters analgesia and secondary the pulmonary function and neuroendocrine response to trauma. METHODS: prospective, controlled, Double-blind study, in which 51 patients scheduled for eletive laparoscopic cholecystectomy were randomly selected and distributed into 2 groups...

Background. Most of the available evidence on the use of indocyanine green (ICG) fluorescence in clinical practice consists of articles published by surgeons of the Asian-Pacific area. We performed a prospective cohort study to assess the patterns of ICG fluorescence in Western hepatocellular carcinoma (HCC) counterparts. Methods. From April 2019 to January 2022, a total of 31 consecutive patients who underwent laparoscopic liver resection (LLR) for superficial HCC were enrolled in this prospective study. All patients underwent laparoscopic staging with both laparoscopic ultrasound (LUS) and ICG fluorescence imaging...

BACKGROUND: The intraoperative evaluation of bronchus perfusion is limited. Hyperspectral Imaging (HSI) is a newly established intraoperative imaging technique that enables a non-invasive, real-time perfusion analysis. Therefore, the purpose of this study was to determine the intraoperative perfusion of bronchus stump and anastomosis during pulmonary resections with HSI. METHODS: In this prospective, IDEAL Stage 2a study ( NCT04784884) HSI measurements were carried out before bronchial dissection and after bronchial stump formation or bronchial anastomosis, respectively...

BACKGROUND/NEED: Pleural empyemas carry a high morbidity and mortality. Some can be managed with medical treatment but most require some form of surgery with the goals to remove the infected material from the pleural space and to help re-expand the collapsed lung. Keyhole surgery by Video Assisted Thoracoscopy Surgery (VATS) is rapidly becoming a common approach to deal with early stage empyemas to avoid larger, more painful thoracotomies that hinder recovery. However, the ability to achieve those aforementioned goals is often hindered by VATS surgery due to the instruments available...

NEED: This study developed a novel automatic stapling device for improving the speed and stability of suturing in laparoscopic surgery. TECHNICAL SOLUTION: The stapling device included 3 components: driver module, actuator module, and transmission module. PROOF OF CONCEPT: A negative water leakage test of the in vitro intestinal defect model preliminarily demonstrated the safety of the new automatic stapling device. The suturing time for skin and peritoneal defects through the automatic stapling device was significantly shorter than that through the ordinary needle-holder suture ( P < ...

Despite the many accomplishments since the introduction of percutaneous dilational (PDT) tracheostomy, we continue to observe emerging complications as we forge ahead in intensive care practice. As a result of this, we provide a new technique that could avoid some complications, notably posterior tracheal wall injury, bronchoscopic or endotracheal tube puncture, and false track. The new technology was evaluated on a 75-year-old Caucasian male cadaver was selected for a novel PDT technique. A wire with a sharp terminal end passed through the bronchoscopic channel and punctured the trachea from inside towards the skin...

BACKGROUND: A significant number of patients with advanced pancreatic cancer are unable to undergo resection due to vascular involvement. Irreversible electroporation (IRE) has shown promise in improving survival. This study sought to assess a novel IRE application whereby IRE was performed pre-resection to alter tissue plasticity and assist tumor removal from underlying vasculature when surgical excision was otherwise precluded. METHODS: After multidisciplinary evaluation appropriate patients were consented for IRE therapy...
