BACKGROUND: Randomized controlled trials (RCTs) inform clinical practice and have provided the evidence base for introducing minimally invasive surgery (MIS) in surgical oncology. Crossover (unplanned intraoperative conversion of MIS to open surgery) may affect clinical outcomes and the effect size generated from RCTs with homogenization of randomized groups. OBJECTIVES: Our aims were to identify modifiable factors associated with crossover and assess the impact of crossover on clinical endpoints...

OBJECTIVE: The minimally invasive approach to colorectal surgery is still underused. Only 50% to 60% of colectomies and 10% to 20% of rectal resections for cancer are performed laparoscopically. The increasing adoption of the robotic platform for colorectal surgery warrants re-evaluation of minimally invasive surgery (MIS) training techniques. Although considering lessons learned from past laparoscopic training, a standardized national robotic training program for colon and rectal surgery residents was developed and implemented in 2011...

BACKGROUND: Cutaneous melanoma is one of the fastest rising cancer diagnoses in recent years. Melanoma in situ (MIS) constitutes a large proportion of all diagnosed melanomas. While surgical excision is considered the standard of therapy, the literature is not clear on which surgical technique minimizes local recurrence. A common technique is serial staged excision (SSE), in which a series of mapped excisions are made according to histopathological examination of tissue. Previously published recurrence rates for SSE ranges from 0-12%, over a range of 4...
