Goal: Accurate prediction of operating room (OR) time is critical for effective utilization of resources, optimal staffing, and reduced costs. Currently, electronic health record (EHR) systems aid OR scheduling by predicting OR time for a specific surgeon and operation. On many occasions, the predicted OR time is subject to manipulation by surgeons during scheduling.

Whereas the advancement of minimally invasive surgical techniques and enhanced recovery after surgery (ERAS) pathways for partial colectomies has shortened postoperative length of stay, the ideal length of stay after partial colectomy with or without diverting loop ileostomy is still up for debate. This article examines the safety and efficacy of discharging select patients home from day surgery following partial colectomy. We performed a retrospective review of 7 patients who underwent partial colectomy at one tertiary care center from December 2020 to August 2021.

Villous adenoma of the genitourinary system is rarely encountered by the general urologist. Although commonly seen in a colorectal practice, this tumor has been infrequently described in the urethra or bladder. In the genitourinary tract, this tumor appears to have excellent survival when isolated; however, it does have an association with adenocarcinoma of the genitourinary or gastrointestinal tract.

The American Recovery and Reinvestment Act mandates "meaningful use" of an electronic health record (EHR) to receive current financial incentives and to avoid future financial penalties. Surgeons' ongoing adoption of an EHR nationally will be influenced by the early experiences of institutions that have made the transition from paper to electronic records. We conducted a survey to query surgeons at our institution regarding their perception of the EHR 3 months after institutional implementation.
