Reversal of Roux-en-Y Gastric Bypass: A Multi-Centric Analysis of Indications, Techniques, and Surgical Outcomes.

Background: Roux-en-Y gastric bypass may present long-term complications that require revisional surgery or even reversal to normal anatomy. Data on the indications, surgical technique, and outcomes of RYGB reversal remain scarce.

Methods: We identified 48 cases of RYGB reversals with complete 90-day follow-up within a multi-centric international retrospective database of elective secondary bariatric surgery.

Ion permeability profiles of renal paracellular channel-forming claudins.

Aim: Members of the claudin protein family are the major constituents of tight junction strands and determine the permeability properties of the paracellular pathway. In the kidney, each nephron segment expresses a distinct subset of claudins that form either barriers against paracellular solute transport or charge- and size-selective paracellular channels. It was the aim of the present study to determine and compare the permeation properties of these renal paracellular ion channel-forming claudins.

Thyroid surgery under nerve auto-fluorescence & artificial intelligence tissue identification software guidance.

Thyroid cancer is a common malignancy that requires comprehensive clinical evaluation prior to adequate surgical management. Over the last three decades thyroid surgery has tripled and is considered one of the most commonly performed procedures in general surgery. These procedures are associated with potential postoperative complications with significant deterioration in the patient's quality of life.

Biomechanical Evaluation of Medial Patellofemoral Ligament Reconstruction Grafts Fixed at Nonanatomic Femoral Insertion Points: MPFL Reconstruction And Femoral Tunnel Location.

Background: Improved patient outcomes and decreased patellar instability have been reported after medial patellofemoral ligament (MPFL) reconstruction for recurrent lateral patellar dislocation; however, there is a lack of comparative evidence on functional outcomes associated with different femoral attachment sites for the MPFL graft.

Purpose: To identify differences in MPFL reconstruction graft isometry with femoral tunnel malpositioning, specifically evaluating isometric differences as the femoral position is moved anterior, posterior, proximal, and distal relative to the Schöttle point, the femoral radiographic landmark of the MPFL.

Study Design: Descriptive laboratory study.

Time-sensitive injuries for the sports medicine surgeon - "Sports Medicine Trauma", Part 1: Upper Extremity.

Skeletal fractures are traumatic injuries that are widely accepted as requiring acute treatment to avoid long-term disability and dysfunction. There are a number of soft-tissue injuries or non-traditional fractures, frequently treated by sports medicine surgeons, which additionally require treatment in an expedited fashion in order to optimize healing and function. Sports medicine injuries of the lower extremity requiring acute treatment include, but are not limited to, irreducible shoulder dislocations, acute traumatic rotator cuff tears, posterior sternoclavicular joint dislocations, high grade acromioclavicular joint dislocations, pectoralis major tendon ruptures, distal biceps tendon ruptures, and triceps tendon ruptures.
