Minimally invasive fluoro-navigation screw fixation for the treatment of pelvic ring injuries.
Intensive use of intraoperative fluoroscopy is mandatory to achieve good accuracy and avoid neural or vascular injury and may prolong surgical time and increase exposure-related hazards. New methods of percutaneous treatment in conjunction with innovative fluoroscopy-based computerized navigation have evolved in an attempt to overcome the existing difficulties. This report described our experience in applying fluoroscopic surgical navigation technique and evaluated its clinical application to pelvic ring injuries, including its feasibility, merits and limitations. ⋯ No superficial or deep infection occurred. No patient sustained recognized neurologic, vascular, or urologic injury as a result of percutaneous screw fixation of pubic ramus fractures, sacroiliac disruptions, or sacral fractures. Our results showed that fluoroscopy-based navigation technique for the pelvic ring injuries could become a safe and effective alterative method for the treatment of pelvic ring injuries in some selected patients.

Cerebrovascular biomodeling for aneurysm surgery: simulation-based training by means of rapid prototyping technologies.
Opportunities for developing procedural skills are progressively rare. Therefore, sophisticated educational tools are highly warranted. ⋯ Simultaneous 3-dimensional printing is the most promising rapid prototyping technique to produce biomodels that meet the high demands of neurovascular surgery.

Multicenter StudyMinimally invasive colorectal resection is associated with a transient increase in plasma hepatocyte growth factor levels early after surgery for colon cancer.
Surgery's impact on blood levels of hepatocyte growth factor (HGF), a potent angiogenic factor, is unknown. Preoperative (PreOp) HGF blood levels are elevated in patients with colorectal cancer (CRC) and correlate with disease stage and prognosis. This study's purpose was to determine plasma HGF levels after minimally invasive colorectal resection (MICR) in patients with CRC. ⋯ MICR for CRC is associated with a 1.9- to 2.3-fold increase in plasma HGF levels during the first 3 PODs after which levels normalize. This transient increase may briefly promote angiogenesis and the growth of residual tumor cells.

EditorialOriginal technique to close the transrectal viscerotomy access in a NOTES transrectal and transgastric segmental colectomy.
Segmental colectomy is an ideal procedure for natural orifice transluminal endoscopic surgery (NOTES). Transanal endoscopic approaches have enabled rectosigmoid colectomy through a viscerotomy that is resected with the specimen. To extend NOTES segmental colectomy to the entire colon and beyond, a rectal viscerotomy will have to be safely and effectively closed at the end of the procedure. A new technique for rectal viscerotomy closure using a circular EEA hemorrhoid and prolapse stapler with DST series technology (Covidien) is described.
