Liposomal bupivacaine interscalene blocks demonstrate a greater proportion of total shoulder arthroplasty patients with clinically tolerable pain: a retrospective quality improvement study of 491 patients.

Objective: To evaluate the effects of liposomal bupivacaine use for interscalene blocks on postoperative analgesia in total shoulder arthroplasty patients.

Methods: De-identified total or reverse total shoulder arthroplasty patients between 2018 and 2021 were analyzed. Patients were grouped into single shot interscalene block with liposomal bupivacaine (LB) with plain bupivacaine, other block (OB) with other local anesthetics (mepivacaine, ropivacaine, or plain bupivacaine), or no block (NB).

Aortic Remodeling and Clinical Outcomes Following Thoracic Endovascular Aortic Repair for Blunt Thoracic Aortic Injury.

Background: There is currently limited data assessing the long-term consequences of thoracic endovascular aortic repair (TEVAR) in otherwise healthy aortic segments remote from the site of endograft coverage. The aim of this study is to retrospectively evaluate aortic remodeling and long-term outcomes of blunt thoracic aortic injury (BTAI) patients treated with TEVAR. Our hypothesis is that significant changes to the aorta proximal to the graft-covered segment are suspected following TEVAR.

Endovascular Strategies in the Management of Acute Limb Ischemia.

Acute limb ischemia (ALI) represents one of the most common emergent scenarios encountered by a vascular specialist. Despite expedient revascularization, high rates of limb loss are reported along with high mortality rates which are second only to ruptured abdominal aortic aneurysms. Surgical revascularization is standard of care.

Teaching peroral endoscopic myotomy (POEM) to surgeons in practice: an "into the fire" pre/post-test curriculum.

Introduction: With the increasing adoption of peroral endoscopic myotomy (POEM) as a first-line therapy for achalasia as well as a growing list of other indications, it is apparent that there is a need for effective training methods for both endoscopists in training and those already in practice. We present a hands-on-focused with pre- and post-testing methodology to teach these skills.

Methods: Six POEM courses were taught by 11 experienced POEM endoscopists at two independent simulation laboratories.
