“Purpose: To present our early experience with retroperitoneal laparoendoscopic single-site (LESS) simple Etomoxir nephrectomy.

Patients and Methods: A total of 16 patients with benign nonfunctioning kidney underwent retroperitoneal LESS nephrectomy by one experienced

laparoscopic surgeon. A single-port access was inserted through an approximately 3-cm lumbar incision made below the 12th rib along the midaxillary line. Standard steps of multisite retroperitoneoscopic nephrectomy technique with a combination of conventional

and bent laparoscopic instruments were performed.

Results: Retroperitoneal LESS nephrectomy was performed in 15 cases successfully. The procedure of one patient (genitourinary tuberculosis) needed conversion to open surgery because of the severe adhesions surrounding the kidney, which resulted in failure to progress. Overall, the mean operative time was 85 (75-140) minutes, and estimated blood loss was 56 (20-110) mL. The mean time to resume oral diet was 1.5 days. The mean postoperative hospital stay was 4 (3-5) days. Perioperative complications were limited to one case of transient postoperative fever. No major intraoperative and postoperative complication occurred.

Conclusions: Selleckchem GW4869 Retroperitoneal LESS nephrectomy performed by an experienced laparoscopic surgeon is feasible and safe, offering improved cosmesis, although it remains technically DMXAA mouse challenging. Retroperitoneal

LESS nephrectomy should be selectively used in terms of patients’ specific conditions.”
“Background-Cardiologists are distributed unevenly across regions of the United States. It is unknown whether patients in regions with fewer cardiologists have worse outcomes after hospitalization for acute myocardial infarction (AMI) or heart failure (HF).

Methods and Results-Using Medicare administrative claims data from 2010, we examined the relationship between regional density of cardiologists and risk of death after hospitalization for AMI and HF using hospitalizations for pneumonia as a comparison. We defined density as the number of cardiologists divided by population aged >= 65 years within hospital referral regions, categorized into quintiles. Among 171 126 admissions for AMI, 352 853 admissions for HF, and 343 053 admissions for pneumonia, we tested associations between density of cardiologists and 30-day and 1-year mortality for each condition. We used 2-level hierarchical logistic regression models that adjusted for characteristics of patients and hospital referral regions. Patients hospitalized for AMI (odds ratios [OR], 1.13; 95% confidence interval [CI], 1.06-1.21) and HF (OR, 1.19; 95% CI, 1.12-1.
