Purpose: This study aimed to evaluate the efficacy of adding a spur valve to laparoscopic portoenterostomy for patients with biliary atresia.
Methods: We retrospectively reviewed the records of all patients diagnosed with biliary atresia (BA) who underwent laparoscopic portoenterostomy (Lap-PE) between 2013 and 2021. The patients were divided into two groups: Lap-PE with a spur valve (spur group) and without it (control group). Perioperative management was the same in both groups. We compared patient backgrounds and clinical outcomes, including jaundice clearance and the number of postoperative cholangitis episodes.
Results: Of 63 patients reviewed, 16 received a spur valve. There were no statistically significant differences in the patient backgrounds between the groups. All patients in the spur group achieved jaundice clearance. The number of postoperative cholangitis episodes one year after surgery was significantly lower in the spur group than in the control group (1 [0-3] vs. 3 [0-9], p = 0.04). The jaundice-free survival rate with the native liver at one year after surgery was significantly higher in the spur group (100% vs. 53%, p = 0.01).
Conclusions: Adding a spur valve during Lap-PE significantly lowered the number of cholangitis episodes 1 year after surgery.

Physical Intelligence Department, Max Planck Institute for Intelligent Systems, 70569 Stuttgart, Germany.
Article Synopsis
- Researchers developed a small, flexible capsule for sampling liquids in tight spaces, which could help monitor health and detect diseases early.
- The capsule uses innovative features like magnetic valves and superabsorbent materials, allowing it to collect fluids without invasive techniques and be controlled remotely.
- Demonstrations showed the capsules effectively navigate and sample body fluids in a lab setting using ultrasound and X-ray imaging, paving the way for advanced diagnostic technologies.

Introduction: Functional septo(rhino)plasty incurs a 17-25% rate of revision for persistent symptoms.
Objectives: The main study objective was to assess functional results before and after surgical revision. The secondary objective was to describe the shortcomings or excesses of the prior surgeries, with a-posteriori comparison of efficacy for the surgical techniques requiring revision.
Association Between Anterior Rhinoscopic/Endoscopic Assessment of Internal Nasal Valve and Various Nasal Deformities in the Rural Population of Vidarbha Region of India: A Cross-Sectional Study.

Background The nasal valves constitute the majority of the nasal cavity's resistance. Any reduction in this already narrow area can cause a significant reduction in the nasal airflow. In this present study, the aim was to do an endoscopic assessment of the internal nasal valve (INV) in patients with various nasal septal deviations, with or without external nasal deformity.

Introduction: The dangers of hyperventilation during resuscitation are well known. Traditional bag valve mask (BVM) devices rely on end users to control tidal volume (V), rate, and peak inspiratory pressures (PIP) of ventilation. The Butterfly BVM (BBVM) is a novel device intending to give greater control over these parameters.
