Laparoscopic versus open partial nephrectomy
Abstract
To compare, retrospectively, the results of laparoscopic partial nephrectomy (LPN) to open partial nephrectomy (OPN) using a tumor size-matched cohort of patients. Limited data are available comparing LPN to OPN in the treatment of small renal tumors. Between September 2000 and September 2003, 27 LPNs and 22 OPNs were performed to treat renal masses less than 4 cm. Patient demographics and tumor location and size (2.4 +/- 1.0 cm versus 2.9 +/- 0.9 cm, respectively; P = not statistically significant) were similar between the LPN and OPN groups. Although the mean operative time was longer in the LPN than in the OPN group (210 +/- 76 minutes versus 144 +/- 24 minutes; P <0.001), the blood loss was comparable between the two groups (250 +/- 250 mL versus 334 +/- 343 mL; P = not statistically significant). No blood transfusions were performed in either group. The hospital stay was significantly reduced after LPN compared with after OPN (2.9 +/- 1.5 days versus 6.4 +/- 1.8 days; P <0.0002), and the postoperative parenteral narcotic requirements were lower in the LPN group (mean morphine equivalent 43 +/- 62 mg versus 187 +/- 71 mg; P <0.02). Three complications occurred in each group. With LPN, no patient had positive margins or tumo...Continue Reading

Blood Clotting Disorders
Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
Cancer Incidence & Mortality
Cancer has emerged as a global concern due to its increase in incidence and mortality. Efforts are underway to evaluate and develop action plans to reduce the global burden of cancer. Currently, lung cancer, breast cancer and prostate cancer are the leading causes of cancer mortality. Here is the latest research on cancer incidence and mortality.
