Skills training plays an increasing role in residency training. Few medical schools have skills courses for senior students entering surgical residency. ⋯ Skills instruction for senior students entering surgical internship results in a higher perception of preparedness and improved skills performance. Medical schools should consider integrating skills courses into the 4(th)-year curriculum to better prepare students for surgical residency.

Enhanced productivity and efficiency in the operating room must be balanced with patient safety and staff satisfaction. In December 2004, transition to an expanded replacement hospital resulted in mandatory overtime, unpredictable work hours, and poor morale among operating room (OR) staff. A staff-retention crisis resulted, which threatened the viability of the OR and the institution. We report the changes implemented to efficiently deliver safe patient care in a supportive environment for surgeons and OR staff. ⋯ Change is difficult to accept but essential when vital clinical activities are impaired and at risk. To maintain important clinical environments like the OR in an academic center, we developed and implemented effective, data-driven changes. This allowed us to retain critical human resources and restore a supportive environment for the patients, the doctors, and the staff.

The mechanism by which pancreatic ductal adenocarcinoma (PDA) cells escape immune detection and survive in lymph nodes is poorly understood. One possible mechanism by which PDA cells can escape immune detection is through upregulation of indoleamine 2,3-dioxygenase (IDO), an enzyme that can starve T lymphocytes of tryptophan. ⋯ These data support the notion that metastatic PDA cells select for overexpression of IDO to evade immunologic detection. Future studies will define whether IDO expression in PDA patients with lymph node-positive metastases correlates with decreased survival. In addition, inhibition of IDO in PDA patients can be useful to enhance immunotherapeutic strategies.

Cardiac injury at the time of resternotomy is a complication faced by all cardiac surgeons, although little is known about its effects on morbidity and mortality. This study was designed to address these questions. ⋯ Cardiac injury at the time of resternotomy is not associated with an increase in perioperative morbidity or mortality. Third-time resternotomy is an independent risk factor for cardiac injury, so vigilance and adequate preparation are paramount in these patients.

The reported incidence of choledochal cyst (CC) disease varies greatly based on geography. Most large series on CC originate from East Asia. So our understanding of the presentation and natural history of CC disease in western societies is less well characterized. Recognition and surgical treatment are important because of the significant longterm risks of developing cholangiocarcinoma. We report here the largest single-institution western experience with CC disease. ⋯ Western CC disease has a similar demographic profile as that seen in Asia. CCs are more frequently found in adults and girls/women and are associated with a longterm risk of developing cholangiocarcinoma. Presentation differs between adults and children. After complete cyst excision, no patients developed cholangiocarcinoma.
