Endobronchial ultrasound bronchoscopy (EBUS) is a minimally invasive and widely utilized endoscopic technique that enables real-time ultrasound visualization of mediastinal and hilar lymph nodes adjacent to the tracheobronchial tree, allowing tissue sampling under direct sonographic guidance. Accessible nodal stations include 1, 2R/L, 3P, 4R/L, 7, 10R/L, and 11R/L; however, stations 5 and 6 are technically more challenging and associated with a higher risk of complications due to their proximity to the aorta and pulmonary vessels.

EBUS can be used for diagnostic, staging, and restaging purposes, particularly in conditions such as lymphoma and sarcoidosis, as demonstrated in the accompanying video. Its diagnostic yield varies according to the underlying pathology and nodal characteristics, and the diagnostic sensitivity for specific diseases is outlined below.

Hepatocellular carcinoma (HCC) is the most common primary liver cancer and is associated with high morbidity and mortality. In this case, the patient was incidentally found to have a segment V/VI lesion consistent with HCC and a IVb lesion indeterminate probability of malignancy. He underwent a robotic-assisted hepatectomy for a segment V/VI lesion with cholecystectomy and evaluation by ultrasound and excisional biopsy of a segment IVb lesion. His postoperative course was unremarkable, and he was discharged on postoperative day four. The pathology demonstrated well-differentiated HCC with resection margins negative for carcinoma. This video demonstrates an experienced surgeon’s technique for performing a robotic hepatectomy for a segment V/VI lesion with cholecystectomy and evaluation by ultrasound and excisional biopsy of a segment IVb lesion. It also highlights effective management of bleeding during hepatic parenchymal transection.

This video provides a step-by-step demonstration of preprocedural neuraxial ultrasound for lumbar neuraxial procedures. The film shows probe selection and orientation, sonoanatomy landmarks (sagittal and transverse views), measurement of skin-to-posterior complex depth, and skin marking. Indications and evidence for improved procedural accuracy and reduced needle passes are discussed. The technique is applicable to routine obstetric neuraxial procedures and is especially useful in patients with challenging surface landmarks or a history of difficult neuraxial placement.

This video covers information related to the FAST exam, which evaluates the pericardial, hepatorenal, splenorenal, and suprapubic regions for free fluid in a trauma patient as well as the extended version, which includes an additional evaluation of the pleural spaces for a pneumothorax. It goes through probe selection, probe placement and image acquisition, image optimization, and pitfalls and pearls for the subxiphoid/subcostal, right upper quadrant, left upper quadrant, suprapubic, and pleural views.

PREPRINT RELEASE: Distal Gastrectomy (Open)

Distal Gastrectomy (Open)

An 80-year-old patient with anemia undergoes an upper endoscopy that reveals inflammation in the distal stomach. Biopsies identify it as an early intramucosal adenocarcinoma while an endoscopic ultrasound shows the tumor invading the muscle of the stomach. Given that there are no signs of metastasis, the patient presents for a potentially curative gastrectomy where Dr. John Mullen removes the distal two-thirds of the stomach, performs a D1 lymph node dissection and a partial D2 lymph node dissection, and reconstructs in a Billroth II fashion.
