Median Nerve and Carpal Tunnel Morphology Before and After Endoscopic Carpal Tunnel Release: A 6-Year Follow-up Study.

BACKGROUND: Our purpose was to describe structural and morphological features of the median nerve and carpal tunnel on magnetic resonance imaging (MRI) studies obtained before, immediately after, 6 weeks after, and 6 years after endoscopic carpal tunnel release (ECTR). METHODS: In this prospective cohort study, 9 patients with a diagnosis of carpal tunnel syndrome (CTS) underwent ECTR. Standardized MRI studies were obtained before ECTR, immediately after ECTR, and 6 weeks and 6 years after surgery. Structural and morphological features of the median nerve and carpal tunnel were measured and assessed for each study with comparisons made between each time point. RESULTS: All 9 patients had complete symptom resolution postoperatively. On the immediate postoperative MRI, there was a discrete gap in the transverse carpal ligament in all patients. There was retinacular regrowth noted at 6 weeks in all cases. The median nerve cross-sectional area and the anterior-posterior dimension of the carpal tunnel at the level of the hamate increased immediately after surgery and these changes were maintained at 6 years. CONCLUSIONS: We defined structural and morphological changes on MRI for the median nerve and carpal tunnel in patients with continued symptom resolution 6 years after ECTR. Changes in median nerve and carpal tunnel morphology that occur immediately after surgery remain unchanged at mid-term follow-up in asymptomatic patients. Established imaging criteria for CTS may not apply to postoperative patients. Magnetic resonance imaging appears to be of limited clinical utility in the workup of persistent or recurrent CTS.

Genetic counseling for hereditary breast and gynecologic cancer syndromes at a community hospital.

Genetic screening and testing has been shown to be medically and emotionally beneficial for patients with a personal history or strong family history of breast, ovarian, and/or colorectal cancer. Gynecologic oncologists increasingly utilize genetic screening to modify their care and treatment plans of patients and their offspring based on inherited susceptibility to cancer. The U.S. Preventive Services Task Force (USPSTF) developed specific criteria that consider the medical, psychosocial, and ethical ramifications of genetic counseling of high-risk individuals. Genetic counseling and screening, along with early intervention, is of benefit to women with family histories suggestive of harboring breast cancer antigen (BRCA) mutations. The Western Connecticut Health Network (WCHN) Hereditary Cancer and Genetic Counseling Program provides a comprehensive cancer risk assessment and offers genetic screening as appropriate. This report describes trends in patient referrals, intake, results of genetic testing, and an expansion of services in a community-based genetic counseling program.
