The pathophysiology of cardio-renal syndrome (CRS) is complex. Hydronephrosis caused by urolithiasis may cause cytokine release and lead to cardiac dysfunction. The aim of this study was to evaluate cardiac function changes observed in patients who received double J placement using feasible biomarkers and echocardiography. This was a prospective, single-center study. Eighty-seven patients who presented with acute unilateral hydronephrosis and received ureteroscope stone manipulation were enrolled. Echocardiography and cytokines were measured on the day of the operation and 24 hours after the procedure...

Percutaneous nephrolithotomy (PCNL) is currently the treatment of choice for large and complex renal calculi. One of the main advantages of PCNL is gaining a real stone-free status in a single session. However, there are several major complications that necessitate careful patient selection for this surgery (1). In this well written manuscript the authors deal with the true rates and importance of residual fragments following PCNL surgeries done in a high volume center. They reviewed 658 PCNL procedures from 2008-2013 that underwent a CT scan on post-operative day one...

There is limited available literature examining factors that predispose patients to the development of LMC after stereotactic radiosurgery (SRS) for brain metastases. We sought to evaluate risk factors that may predispose patients to LMC after SRS treatment in this case-control study of patients with brain metastases who underwent single-fraction SRS between 2011 and 2016. Demographic and clinical information were collected retrospectively for 19 LMC cases and 30 controls out of 413 screened patients with brain metastases...

The capture of peritoneal metastatic cancer stem cell of human gastric cancer (pMCSC-hGC) is important to further understand the mechanism of peritoneal metastasis in gastric cancer patients. Previously, cancer stem cells (CSCs) of gastric and rectal cancers were captured and identified. However, the bottleneck of capturing pMCSC-hGC may be the scarce surgical specimen and limited volume of peritoneal metastatic lesions from gastric cancer. Only 5.2% of patients were diagnosed of unpredictive peritoneal seeding intraoperatively, while none cell sphere were successfully formed through the identical culture approach based on peritoneal metastatic nodules...

PURPOSE: To propose contouring guidelines based on consensus contours generated by 10 international experts for cavity stereotactic radiosurgery (SRS), an emerging treatment option after surgical resection of brain metastases. No guidelines for contouring the surgical cavity volume have been previously reported. METHODS AND MATERIALS: Ten postoperative completely resected cases with varying clinical scenarios and locations within the brain were selected. For each case, 10 experts independently contoured the surgical cavity clinical target volume (CTV)...

Pancreatic cancer is the fourth leading cause of cancer-related death in the Unites States and is rising in incidence. For the 15-25% of patients who do not have either metastatic or locally advanced disease, surgical resection with pancreaticoduodenectomy is the standard of care and results in improved 5-year survival of 15-25%. While mortality at high-volume centers is less than 5%, morbidity remains high at approximately 30-45%. This paper reviews technical aspects of pancreaticoduodenectomy and their outcomes...

PURPOSE: Underinsured patients are less likely to receive complex cancer operations at hospitals with high surgical volumes (high-volume hospitals, or HVHs), which contributes to disparities in care. To date, the impact of insurance coverage expansion on site of complex cancer surgery remains unknown. METHODS: Using the 2006 Massachusetts coverage expansion as a natural experiment, we searched the Hospital Cost and Utilization Project state inpatient databases for Massachusetts and control states (New York, New Jersey, and Florida) between 2001 and 2011 to evaluate changes in the utilization of HVHs for resections of bladder, esophageal, stomach, pancreatic, rectal, or lung cancer after the expansion of insurance coverage...

BACKGROUND CONTEXT: Post-operative pain at the site of bone graft harvest for posterior spine fusion is reported to occur in 6% to 39% of cases. However, the area around the posterior, superior iliac spine is a frequent site of referred pain for many structures. Therefore, many postoperative spine patients may have pain in the vicinity of the posterior iliac crest that may not in fact be caused by bone graft harvesting. The literature may then overestimate the true incidence of postoperative iliac crest pain...

PURPOSE: Patients readmitted to secondary hospitals rather than the primary hospital where their surgery took place may be at risk for poorer outcomes. We sought to evaluate the effect of site of readmission on failure-to-rescue complication rates following urologic cancer surgery. MATERIALS AND METHODS: Retrospective review of major urologic cancer surgeries in the Washington State Comprehensive Hospital Abstract Reporting System between 1998 and 2013. Failure-to-rescue (FTR) rates, defined as inpatient death after a complication requiring hospital readmission, were compared between patients readmitted to their primary hospital with those readmitted to a secondary hospital...

The Prostate Testing for Cancer and Treatment (ProtecT) trial reported excellent outcomes for patients with localized prostate cancer (PCa) managed with radical prostatectomy (RP), radiotherapy, or active monitoring. We aimed at assessing the generalizability of the ProtecT trial to contemporary patients undergoing RP at two high-volume institutions. Overall, 29147 PCa patients treated with RP between 1999 and 2016 were included. We evaluated changes in disease characteristics over time. Competing-risk analyses estimated the 10-yr cancer-specific mortality (CSM) and other-cause mortality (OCM) rates...

OBJECTIVES: The goal of this study was to explore sex differences in myocardial remodeling in aortic stenosis (AS) by using echocardiography, cardiac magnetic resonance (CMR), and biomarkers. BACKGROUND: AS is a disease of both valve and left ventricle (LV). Sex differences in LV remodeling are reported in AS and may play a role in disease phenotyping. METHODS: This study was a prospective assessment of patients awaiting surgical valve replacement for severe AS using echocardiography, the 6-min walking test, biomarkers (high-sensitivity troponin T and N-terminal pro-brain natriuretic peptide), and CMR with late gadolinium enhancement and extracellular volume fraction, which dichotomizes the myocardium into matrix and cell volumes...

BACKGROUND: Perioperative aspiration leads to significant morbidity and mortality. Standard fasting periods are used to ensure an empty stomach in patients. Anesthesiologists are frequently confronted with cases of dubious adherence to these guidelines. Point-of-care gastric ultrasound is a diagnostic tool that offers information on the type and volume of gastric contents. METHODS: We performed a retrospective analysis of a departmental database containing clinical and sonographic information on elective surgical patients who had been non- compliant to the fasting guidelines...

Large lobar intracerebral hemorrhages (ICHs) can cause rapid neurological deterioration, and affected patients have low rates of survival and functional independence. Currently, the role of surgical intervention in the management patients with lobar ICHs is controversial. Minimally invasive technologies have been developed which may potentially decrease the operative morbidity of ICH surgery. The aim of this case report is to describe the technical aspects of the use of a novel minimally invasive endoport system, the BrainPath (NICO, Indianapolis, IN, USA), through an eyebrow incision for evacuation of a large lobar hematoma...

INTRODUCTION: During brain tumour surgery, vasopressor drugs are commonly administered to increase mean arterial blood pressure with the aim of maintaining sufficient cerebral perfusion pressure. Studies of the commonly used vasopressors show that brain oxygen saturation is reduced after phenylephrine administration, but unaltered by ephedrine administration. These findings may be explained by different effects of phenylephrine and ephedrine on the cerebral microcirculation, in particular the capillary transit-time heterogeneity, which determines oxygen extraction efficacy...

REVIEW
Ashraf Fayad, Sasha K Shillcutt
PURPOSE: The use of transesophageal echocardiography (TEE) has evolved to include patients undergoing high-risk non-cardiac procedures and patients with significant cardiac disease undergoing non-cardiac surgery. Implementation of basic TEE education in training programs has increased across a broad spectrum of procedures in the perioperative arena. This paper describes the use of perioperative TEE in non-cardiac surgery and provides an overview of the basic TEE examination. PRINCIPAL FINDINGS: Perioperative TEE is used to monitor hemodynamic parameters in non-cardiac procedures where there is a high risk of hemodynamic instability...
