Effects of Thoracic Epidural Anaesthesia on the Serosal Microcirculation of the Human Small Intestine
ConclusionWe examined the effects of TEA on the intestinal serosal microcirculation during abdominal surgery using IDF imaging for the first time in patients. Regardless of a marked decrease in hemodynamics, microcirculatory parameters of the bowel serosa were not significantly affected.Trial registry numberClinicalTrials.gov identifier NCT02688946.

Perioperative Outcomes of Laparoscopic Minor Hepatectomy for Hepatocellular Carcinoma in the Elderly
ConclusionLMH is safe and feasible in elderly patients with HCC. However, LMH in elderly patients is associated with poorer perioperative outcomes compared to LMH in young patients. Comparison between LMH and OMH in elderly patients demonstrated advantages in terms of decreased pulmonary complications and shorter length of stay at the expense of increased operation time and blood loss.

Robotic Reoperative Anti-reflux Surgery: Low Perioperative Morbidity and High Symptom Resolution
AbstractBackgroundLaparoscopic reoperative anti-reflux surgery (ARS) has a significantly higher morbidity than laparoscopic primary ARS; however, it is not known whether the same pattern exists within the robotic approach. We aimed to evaluate the safety and efficacy of robotic reoperative ARS in comparison with primary robotic ARS.MethodsA retrospective review of patients undergoing primary or reoperative robotic ARS at a tertiary referral center between 2012 and 2017 was performed. Perioperative outcomes and long-term symptom resolution were evaluated.ResultsA total of 200 patients were included (38 reoperative and 162 p...

The Use of Three-Dimensional Printing Model in the Training of Choledochoscopy Techniques
AbstractAimTo evaluate the application value of a three-dimensional (3D) printing model in the training of choledochoscopy techniques.Materials and methodsImaging data from two patients with biliary dilatation were used to produce two 3D reconstruction models which were subsequently constructed into 3D printing models (No. 1 and No. 2). Four hepatobiliary surgeons evaluated the anatomical accuracy and academic teaching value of the printed models. Twenty resident trainees with no prior experience in any kind of endoscopic techniques were randomly and symmetrically divided into two groups. The training group (A) used the 3D...

Soluble Urokinase Plasminogen Activator Receptor (suPAR) as an Added Predictor to Existing Preoperative Risk Assessments
AbstractBackgroundRisk assessment strategies, such as using the American Society of Anesthesiologists (ASA) physical status classification, attempt to identify surgical high-risk patients. Soluble urokinase plasminogen activator receptor (suPAR) is a biomarker reflecting overall systemic inflammation and immune activation, and it could potentially improve the identification of high-risk surgical patients.MethodsWe included patients acutely admitted to the emergency department who subsequently underwent surgery within 90  days of admission. Patients were stratified into low-risk or high-risk groups, according to ASA cl...
