BACKGROUND: Although endoscopic resection (ER) may be sufficient treatment for early-stage esophageal cancer, additional treatment is recommended when there is a high risk of cancer recurrence. It is unclear whether delaying esophagectomy by performing and assessing the success of ER affects outcomes as compared with immediate esophagectomy without ER. Additionally, long-term survival after sequential ER and esophagectomy required further investigation. METHODS: Between 2011 and 2015, 48 patients with stage T1 esophageal cancer underwent esophagectomy after ER with curative intent at our institution...

BACKGROUND: Conversion from minimally invasive to open colorectal surgery remains common and costly. Robotic colorectal surgery is associated with lower rates of conversion than laparoscopy, but institutions and payers remain concerned about equipment and implementation costs. Recognizing that reimbursement reform and bundled payments expand perspectives on cost to include the entire surgical episode, we evaluated the role of minimally invasive conversion in total payments. METHODS: This is an observational study from a linked data registry including clinical data from the Michigan Surgical Quality Collaborative and payment data from the Michigan Value Collaborative between July 2012 and April 2015...
