Objective: To analyze the effect of learning in two surgeons on complications and conversion to laparotomy during total and subtotal laparoscopic hysterectomy.
Material And Methods: We analyzed retrospectively 236 total and subtotal laparoscopic hysterectomies done by two surgeons from the time they first performed the procedure. The interventions were classified in three groups based on the surgeon's experience: the first 75 hysterectomies ("novice period"), the subsequent 75 hysterectomies ("intermediate"), and the subsequent 86 hysterectomies ("routine period").
Results: Patient's characteristics changed as surgeons gained experience, with more complex operations (greater obesity, previous surgery and malignant disease) becoming more frequent. During the second group of operations when surgeons had an intermediate level of experience, the risk of major complications decreased (adjusted odds ratio: 0.28, 95% confidence interval: 0.10-0.85), as did the risk of type III complications of Clavien-Dindo classification (adjusted odds ratio 0.15, 95% confidence interval: 0.03-0.93). However, the percent rate of conversion to laparotomy remained stable in the second (intermediate experience) group. In the third group, after the surgeons had performed 150 procedures and when the risk of any type of complication was lowest, the risk of conversion to laparotomy decreased compared to the routine group.
Conclusions: The surgeon's experience in performing laparoscopic hysterectomy plays an essential role in the decrease in the risk of complications, and this finding supports the importance of providing appropriate training for residents and gynecologists to enable them to perform this procedure with an optimal degree of competence and safety.

Impact of Frailty on Surgical Outcomes of Patients With Cushing Disease Using the Multicenter Registry of Adenomas of the Pituitary and Related Disorders Registry.
Neurosurgery
February 2025
Global Neurosciences Institute, Philadelphia , Pennsylvania , USA.
Background And Objectives: Despite growing interest in how patient frailty affects outcomes (eg, in neuro-oncology), its role after transsphenoidal surgery for Cushing disease (CD) remains unclear. We evaluated the effect of frailty on CD outcomes using the Registry of Adenomas of the Pituitary and Related Disorders (RAPID) data set from a collaboration of US academic pituitary centers.
Methods: Data on consecutive surgically treated patients with CD (2011-2023) were compiled using the 11-factor modified frailty index.
Evaluating the value of 3D-printed bone models with fracture fragments connected by flexible rods for training and preoperative planning.
3D Print Med
January 2025
AO Innovation Translation Center (AO ITC), AO Foundation, Davos, Switzerland.
Background: The emergence of 3D printing has revolutionized medical training and preoperative planning. However, existing models have limitations, prompting the development of newly designed flexible 3D-printed bone fracture models.
Methods: The designed flexible 3D-printed bone fracture models were evaluated by 133 trauma surgeons with different levels of experience for perceived value as educational tool or as preoperative planning tool.
Management of deep neck space infections - an Australian otolaryngology experience.
ANZ J Surg

Otolaryngology Head and Neck Surgery Department, Western Health, Footscray, Victoria, Australia.
Background: Deep neck space infections (DNSI) are common, potentially life-threatening presentations in otolaryngology. Treatment is often based on the severity of presenting symptoms and surgeon preference. This study aims to evaluate the presentation and predictors of complications in patients presenting with DNSI at an Australian Otolaryngology referral centre.

Department of Surgery, David Geffen School of Medicine, University of California Los Angeles, Los Angeles, CA.
Objective: To characterize contemporary surgeons' viewpoints and perspectives on the academic mission during healthcare corporatization.
Summary Background Data: Academic surgery, traditionally driven by the tripartite missions of excellence in clinical care, scientific research, and education, faces increasing challenges from a corporatized healthcare environment. While previous studies have addressed the financial aspects of corporatization, a comprehensive evaluation of academic surgeons' attitudes and experiences remains lacking.
Microanastomosis in large vessel size discrepancies: A novel training model.
JPRAS Open
March 2025
Plastic and Reconstructive Surgery Department, Hospital Clinic of Barcelona, Barcelona, Spain.
Introduction: Different vessel diameters may challenge the completion of a high-quality anastomosis in microsurgery. In clinical practice, discrepancies in vessel size are commonly encountered. These variations can range from small to moderate, and microsurgeons typically employ established techniques, such as dilating the smaller vessel or creating an oblique cut in its wall, to address these differences.
