Randomized Controlled Trial Comparative Study Clinical Trial
Percutaneous versus surgical tracheostomy: a double-blind randomized trial.
To compare surgical (SgT) and percutaneous (PcT) tracheostomies. ⋯ Both techniques are associated with a low rate of serious or intermediate complications when performed by experienced surgeons. There were more minor perioperative complications with PcT and more minor long term complications with SgT.

To evaluate surgical complications, patterns of lymph node metastases, and calcitonin response to compartment-oriented lymphadenectomy in patients with primary or recurrent medullary thyroid carcinoma (MTC). ⋯ Compartment-oriented lymphadenectomy performed early in the course of MTC is safe and may return calcitonin levels to normal in up to 25% of carefully selected patients. However, reoperation for bulky cervical disease (group 3) rarely results in normal calcitonin levels and is associated with a high incidence of permanent hypoparathyroidism.

Comparative Study Clinical Trial
Prospective comparison of standard triple assessment and dynamic magnetic resonance imaging of the breast for the evaluation of symptomatic breast lesions.
To compare the sensitivity and specificity of the traditional triple assessment of symptomatic breast lesions with contrast-enhanced dynamic magnetic resonance imaging. ⋯ Contrast-enhanced dynamic magnetic resonance imaging of the breast is as sensitive and more specific than the combined traditional triple assessment for the diagnosis of malignant breast lesions.
-
To determine the overall and complication-related readmission rates within 30 days after ambulatory surgery at a major ambulatory surgical center. ⋯ The rate of complication-related readmissions was extremely low (0.15%). This result further supports the view that ambulatory surgery is a safe practice.

To review the outcome data for colectomy performed for patients with slow transit constipation (STC). ⋯ It may be possible to predict outcome on the basis of preoperative clinical and pathophysiologic findings. This review suggests a rationale for the selection of patients for colectomy.
