And out of that maybe 1 in 12 (less than 8%) will have the need for surgery, whether it is elective or emergency. With these numbers it helps to know and understand when surgery is usually recommended and what these surgeries entail. Sometimes when a patient may have such severe diverticular disease their surgeon may recommend planning ahead for surgery, this is generally done to avoid the high...

A methodology has been developed to determine the relative values of surgical procedures and medical office visits on the basis of resource costs. The time taken to perform the service and the complexity of that service are the most critical variables. Inter-specialty differences in the opportunity costs of training and overhead expenses are also considered. Results indicate some important diff...

It is shown that any closed three-manifold M obtained by integral surgery on a knot in the three-sphere can always be constructed from integral surgeries on a 3-component link L with each component being an unknot in the three-sphere. It is also interesting to notice that infinitely many different integral surgeries on the same link L could give the same three-manifold M .

BACKGROUND AND OBJECTIVES Surgical trials pose many methodological challenges often not present in trials of medical interventions. If not properly accounted for, these challenges may introduce significant biases and threaten the validity of the results. METHODS We systematically reviewed the significance of randomized controlled trials in the evaluation of surgical interventions, discussed t...

With the help of new support technology, oral implants can be planned and carried out in altogether new dimensions. The clinician is no longer restricted to his or her experience and the use of two-dimensional image-based procedures. The Stryker Leibinger navigation system now enables surgical planning based on three-dimensional models that can be endlessly manipulated; it produces an intraoper...

The development of a computer based orthopaedic surgical system, with a clear surgical application and a commercial objective, requires the identification of the orthopaedic surgical principle it aims to solve. Other requirements of such a system include: its perceived advantages, its surgically acceptable format and the issues that will be encountered during its development. This paper identif...

Introduction: Ensuring maximum patient safety as well as a complete surgical experience is of utmost importance in training for plastic surgery. As plastic surgical training relies on resident participation in various procedures, we must guarantee adequate hands-on operative time while maintaining the best possible outcomes for the patient. The effect of resident involvement on the outcomes of ...

OBJECTIVES To evaluate the learning curves of three high-volume procedures, from distinct surgical specialties. SETTING Tertiary care academic hospital. PARTICIPANTS A prospectively collected database comprising all medical records of patients undergoing isolated coronary artery bypass grafting (CABG), total knee replacement (TKR) and bilateral reduction mammoplasty (BRM) at the Brigham and...

conclusions aki is common in urology patients. the underlying aetiologies of aki in this group may explain a lower overall mortality, although increasing aki severity remains a marker of patients at higher risk of poor outcomes. the low rate of renal recovery suggests that urology patients who sustain aki are exposed to a significant risk of ckd and its attendant consequences for long term heal...
