Review Meta Analysis Comparative StudyA meta-analysis comparing lightweight meshes with heavyweight meshes in Lichtenstein inguinal hernia repair.
To evaluate the influence of lightweight and heavyweight mesh on postoperative recovery in Lichtenstein inguinal hernia repair. ⋯ Current evidence suggests that the use of a lightweight mesh is associated with less postoperative pain and less sensation of a foreign body, without increasing the incidence of recurrence. Further high-quality, long-term follow-up RCTs are needed to provide more reliable evidence.

Clinical TrialThe "AMID" hernia and skin stapler for Lichtenstein hernia repair: a pilot study.
The Lichtenstein hernia repair is a widely accepted and durable treatment option for groin hernias, but acute and chronic postoperative pain for inguinal hernia repair remains a significant issue. The aim of this study was to demonstrate the benefit of a novel hernia stapler on acute postoperative pain after a Lichtenstein hernia repair. ⋯ The Lichtenstein hernia repair using the AMID Stapler is simple and safe and resulted in lower acute postoperative pain and lower analgesic consumption as compared with the sutured Lichtenstein hernia repair. A multicenter clinical trial with a large sample size is needed to more accurately study pain reduction.

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.
