Background/Aims: To evaluate the feasibility and safety of single-port access total laparoscopic hysterectomy (SPA-TLH) for large uterus (>500 g). Methods: A prospective data collection was performed in 21 consecutive patients in March 2010 and August 2011. Surgical outcome including operative time (OT) and estimated blood loss (EBL) were analyzed. Results: SPA-TLH procedures were successfully performed in 16 cases (76.2%). Of the 5 failed cases, 4 were converted to multiport TLH because of distorted uterine contours and pelvic adhesions and 1 was converted to laparotomy for bleeding control. The median OT, uterine weight, and EBL were 110 (65–165) min, 600 (502–980) g, and 200 (100–800) ml, respectively. Spearman’s correlation analysis demonstrated that OT and blood loss increased with increasing uterine weight (p = 0.003 and p = 0.033, respectively). No operative complications were observed during the hospital stay and 3-month follow-up following discharge. Conclusion: SPA-TLH for large uterus is a feasible and safe technique.
Nanostructured Ag thin films could be facilely prepared by soaking glass substrates in ethanolic solutions containing Ag 2 O powders at an elevated temperature. The formation of zero-valent Ag was corroborated using X-ray diffraction and X-ray photoelectron spectroscopy. The deposition of Ag onto a glass substrate was readily controlled simply by changing the reaction time. Due to the aggregated structures of Ag, the surfaceenhanced Raman scattering spectra of benzenethiol could be clearly identified using the Ag-coated glass. The enhancement factor at 514.5 nm excitation estimated using benzenethiol reached 1.0 × 10 5 while the detection limit of rhodamine 6G was found to be as low as 1.0 × 10 −13 M. Since this one-pot fabrication method is ecofriendly and is suitable for the mass production of diverse Ag films, it is expected to play a significant role in the development of surface plasmon-based analytical devices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
