Background: When we began laparoscopic cholecystectomy (LC) we set up a strict preoperative workup in order to assess whether currently available investigations could help predict difficult laparoscopic procedures.
Methods: Reported here are the results of a prospective trial carried out in our first 200 consecutive patients, who underwent routine intravenous cholangiography (IVC), abdominal ultrasound scan (US), blood tests-namely, markers of biliary stasis (MBS)-and preoperative endoscopic retrograde cholangiopancreatography (ERCP) in case of clinically suspected common bile duct stones (CBDS).
Results: On the basis of our experience we think that the US findings relate to the difficulty of the laparoscopic procedure more closely than the other preoperative investigations, and the association of US and liver chemistry provides an accurate evaluation of biliary stones.
Conclusions: In agreement with data emerging from the literature, the preoperative investigations do not seem to be useful in predicting biliary and vascular complications, whose prevention lies in the adoption of correct surgical technique and a low threshold for conversion.

Division of Cardiothoracic Surgery, University of Utah Health, Salt Lake City, UT. Electronic address:
Background: Prior investigations of the center-specific case volume on outcomes in hypoplastic left heart syndrome have conflicting results. This study utilized the National Pediatric Cardiology Quality Improvement Collaborative (NPC-QIC) registry to investigate the center volume-outcome relationship in patients following the Norwood procedure with consideration of pre-operative high-risk features.
Methods: Between 2016 and 2023, centers were categorized by Norwood procedure volume into low (≤ 5 cases/year), medium (6 to 10 cases/year), and high-volume centers (> 10 cases/year).

Introduction: The Rutherford Classification for chronic limb-threatening ischemia (CLTI) is used to categorize peripheral artery disease severity through history and physical examination. This study investigated whether higher Rutherford Classification correlates with worse clinical outcomes and could serve as a predictive tool.
Methods: In this prospective single-center study , 252 patients undergoing lower extremity revascularization were followed for three years (2020-2023).
Pre-induction and post-discharge venous thromboembolism chemoprophylaxis should be considered in patients after major vascular open abdominal procedures.

Background: Venous thromboembolism (VTE) is a significant morbidity following major open abdominal surgery. While there are clear recommendations for perioperative and post-discharge VTE chemoprophylaxis in general surgery, guidance for vascular patients is unclear. We compared the incidence of VTE in vascular versus general surgery cases and then investigated the timing of VTE in vascular patients.

Background: Iron deficiency (ID) is the most common nutritional deficiency among patients undergoing major surgery. Treatment of ID is straightforward, however implementing a comprehensive anemia management strategy within clinical routines is complex. Recently, reticulocyte hemoglobin content (Ret-He) has been evaluated as an early marker for ID diagnosis.

Department of Neurological Surgery, University of Miami Miller School of Medicine, 1095 NW 14th Terrace, 2nd Floor, Miami, Fl, 33136, USA.
Purpose: Prolonged length of stay (PLOS) can lead to resource misallocation and higher complication risks. However, there is no consensus on defining PLOS for endoscopic transsphenoidal pituitary surgery (ETPS). Therefore, we investigated the impact of varying PLOS definitions on factors associated with PLOS in patients undergoing ETPS.
