Transanal Minimally Invasive Surgery: A Useful Technique That Continues to Evolve.

Colorectal cancer remains the 3rd most common cancer diagnosed among men and women in the United States. With improved screening, premalignant rectal lesions and rectal cancers are being detected at earlier stages. In addition, the use of neoadjuvant chemo- and radiotherapy has led to downstaging of larger lesions.

Screening for osteoporosis after trauma: a new approach using quantitative computed tomography of the skull.

Background: The diagnosis of osteoporosis is important in the care of elderly patients at risk of trauma. While pelvis computed tomography (CT) is accurate in the measurement of bone mineral density, axial skull CT has not previously been evaluated for this purpose. This study investigated whether data from axial skull CT scans can screen for osteoporosis.

Transanal minimally invasive surgery (TAMIS) for local excision of benign neoplasms and early-stage rectal cancer: efficacy and outcomes in the first 50 patients.

Background: Since its inception in 2009, transanal minimally invasive surgery has been used increasingly in the United States and internationally as an alternative to local excision and transanal endoscopic microsurgery for local excision of neoplasms in the distal and mid rectum. Despite its increasing acceptance, the clinical benefits of transanal minimally invasive surgery have not yet been validated.

Objective: The aim of this study is to assess the adequacy of transanal minimally invasive surgery for the local excision of benign and malignant lesions of the rectum.

The mortality risk from motor vehicle injuries in California has increased during the last decade.

Background: Organized trauma systems and trauma centers are thought to improve trauma outcomes. It is clear that injured patients who receive care in trauma centers have survival advantages. However, large regions of California still do not have access to trauma centers.
