Robotic-assisted laparoscopic surgery (RALS) is evolving as an important surgical approach in the field of colorectal surgery. We aimed to evaluate the learning curve for RALS procedures involving resections of the rectum and rectosigmoid. A series of 50 consecutive RALS procedures were performed between August 2008 and September 2009. Data were entered(More)
Single-incision laparoscopic surgery is an emerging modality that has proven to be safe and feasible for colon resection in multiple case reports and series. Nonetheless, comparative analyses with established techniques are limited in the published literature. We evaluated the efficacy of single-incision laparoscopic colectomy (SILC) for the treatment of(More)
BACKGROUND Transanal endoscopic microsurgery is a safe and efficacious surgical approach for local excision of benign adenomas and early-stage rectal cancer. However, utilization of the technique has been limited due to the unavailability of high-priced specialized instrumentation at many institutions and the technically demanding training required. To(More)
Single-incision laparoscopic colorectal surgery is an emerging modality. We incorporated this technique as an alternative to hand-assisted laparoscopic surgery. We investigated intraoperative and short-term outcomes following single-incision laparoscopic colectomy compared with hand-assisted laparoscopic colectomy. Between July and November 2009,(More)
Single-incision laparoscopic colectomy (SILC) is rapidly emerging in the field of minimally invasive colon and rectal surgery. This report presents the safety and feasibility of performing SILC right hemicolectomy with the SILS™ Port Multiple Instrument Access Port. Between July 2009 and October 2009, SILC right hemicolectomy was performed for 13(More)
The da Vinci® Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) is a computer-assisted (robotic) surgical system designed to enable and enhance minimally invasive surgery. The Food and Drug Administration (FDA) has cleared computer-assisted surgical systems for use by trained physicians in an operating room environment for laparoscopic surgical(More)
Surgical value is based on optimizing clinical and financial outcomes. The clinical benefits of laparoscopic surgery are well established; however, many patients are still not offered a laparoscopic procedure. Our objective was to compare the modern clinical and financial outcomes of laparoscopic and open colorectal surgery. The Premier Perspective database(More)
PURPOSE Rectal instillation of 4 percent formalin solution has been described as a successful treatment for hemorrhagic radiation proctitis recalcitrant to medical treatment. We present our experience with a new method of treatment involving the topical application of 10 percent buffered formalin, which is well tolerated and suitable for office use. (More)
A new liquid chromatographic-mass spectrometric (LC-MS) method for determining trace concentrations of gamma-hydroxybutyric acid (GHB) in biological samples has been developed. This method utilizes solid-phase extraction for separation, deuterated GHB as an internal standard (IS) and multiple reaction monitoring (MRM) in the negative ion mode to detect the(More)
