BACKGROUND: Radioactive seed localisation (RSL) is a preoperative localisation method using a small titanium seed containing iodine-125. The method is increasingly applied for localising non-palpable lesions in the treatment of breast cancer. We believe that RSL has the potential to be used in various surgical specialties. The aim of this feasibility study was to test RSL as a preoperative localisation of non-palpable lymph nodes. METHODS: Between November 24, 2015 and October 26, 2016, 15 patients with suspicious lymph nodes on imaging were included in the study...

Prostate cancer is commonly diagnosed by using a transrectal ultrasound (TRUS)-guided biopsy. Although this procedure is usually well tolerated, rarely it may be complicated by massive rectal bleeding. We report a case of a 77-year-old male who underwent a TRUS biopsy and subsequently developed recurrent episodes of rectal bleeding with syncope and anemia requiring the transfusion of multiple units of blood. A sigmoidoscopy revealed the source of the bleeding: a large hemorrhoid on the anterior wall of the rectum with an overlying ulceration...

BACKGROUND: It has been suggested that EUS-BD may be a feasible and safer alternative to percutaneous transhepatic biliary drainage (PTBD) after failed ERCP in patients with ascites. To date, no study has specifically evaluated the performance of EUS-BD in this context. METHODS: Retrospective analysis was done for patients with and without ascites who underwent EUS-BD for malignant biliary obstruction after failed ERCP between July 2010 and September 2014. Complications and technical and clinical successes between the two groups were compared...

BACKGROUND: Surgeon-performed periarticular injections and anesthesiologist-performed femoral nerve or adductor canal blocks with local anesthetic are in common use as part of multimodal pain management regimens for patients undergoing TKA. However, femoral nerve blocks risk causing quadriceps weakness and falls, and anesthesiologist-performed adductor canal blocks are costly in time and resources and may be unreliable. We investigated the feasibility of a surgeon-performed saphenous nerve ("adductor canal") block from within the knee at the time of TKA...

BACKGROUND & AIMS: Cellular and nuclear material from tumors disseminates into the bloodstream (tumoremia), but it is not clear whether medical procedures cause release of this material or contribute to formation of metastases. We performed a prospective study of blood samples from patients with pancreatic adenocarcinoma (PDAC) to determine whether endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) associates with markers of tumoremia. METHODS: We obtained peripheral blood from 104 patients (35 with PDAC) before and after EUS-FNA of primary tumors; blood samples from 69 healthy individuals were used as controls...

A retrospective study was carried out to evaluate the diagnostic accuracy and the factors influencing the diagnostic accuracy of 648 procedures of ultrasound-guided percutaneous needle biopsy (PNB) for peripheral pulmonary lesions (PPLs). We reviewed the histopathology results, the clinical records and the procedure reports of these 648 biopsies and the final diagnoses of 637 PPLs to determine the diagnostic accuracy of ultrasound-guided PNB. Factors that influenced the diagnostic accuracy were assessed by analysis of the biopsy procedures, which were classified as diagnostic cases (true-positive and true-negative) and non-diagnostic cases (false-positive, false-negative and indeterminate)...

INTRODUCTION: The risks of exposure to medical ionizing radiation is of increasing concern both among medical professionals and the general public. Patients with nephrolithiasis are exposed to high levels of ionizing radiation through both diagnostic and therapeutic modalities. Endourologists who perform a high-volume of fluoroscopy guided procedures are also exposed to significant quantities of ionizing radiation. The combination of judicious use of radiation-based imaging modalities, application of new imaging techniques such as ultra-low dose computed tomography (CT) scan, and modifying use of current technology such as increasing ultrasound and pulsed fluoroscopy utilization offers the possibility of significantly reducing radiation exposure...

The prevalence of carpal tunnel syndrome(CTS) in patients that suffer from post-polio syndrome occurs at a rate of 22%.[1] Irrespective of those with CTS, 74% of post-polio patients weight bear through their arms for ambulation or transfers.[1] As open carpal tunnel release is performed along the weight bearing region of the wrist, their functional independence may be altered while recovering. This case demonstrates that ultrasound guided carpal tunnel release(USCTR) was successfully performed in a patient with post-polio syndrome allowing him to immediately weight bear through his hands after the procedure so he could recover at home...
