Multicenter Study
Where Is the Value in Ambulatory Versus Inpatient Surgery?
The aim of this study was to estimate the effect of index surgical care setting on perioperative costs and readmission rates across 4 common elective general surgery procedures. ⋯ Ambulatory surgery offers significant costs savings and generally superior 30-day outcomes relative to inpatient-based care for appropriately selected patients across 4 common elective general surgery procedures.

Multicenter Study Comparative Study
An International Comparison of the Management of Gastrointestinal Surgical Emergencies in Octogenarians-England versus United States: A National Population-based Cohort Study.
To compare the United States and England for the utilization of surgical intervention and in-hospital mortality from 5 gastrointestinal emergencies in octogenarians. ⋯ Surgery is used less commonly in England for emergency gastrointestinal conditions in octogenarians, which may be associated with a high rate of in-hospital mortality from these conditions compared with the USA.

Randomized Controlled Trial Multicenter Study
Resection of Cavity Shave Margins in Stage 0-III Breast Cancer Patients Undergoing Breast Conserving Surgery: A Prospective Multicenter Randomized Controlled Trial.
Single-center studies have demonstrated that resection of cavity shave margins (CSM) halves the rate of positive margins and re-excision in breast cancer patients undergoing partial mastectomy (PM). We sought to determine if these findings were externally generalizable across practice settings. ⋯ Resection of CSM significantly reduces positive margin and re-excision rates in patients undergoing PM.

Multicenter Study Clinical Trial
Comprehensive Learning Curve of Robotic Surgery: Discovery From a Multicenter Prospective Trial of Robotic Gastrectomy.
To evaluate the complication-based learning curve and identify learning-associated complications of robotic gastrectomy. ⋯ This is the first study suggesting that technical immaturity substantially affects the surgical outcomes of robotic gastrectomy and that robotic gastrectomy is a complex procedure with a significant learning curve that has implications for physician training and credentialing.

Multicenter Study
Prediction Model of Long-term Survival After Esophageal Cancer Surgery.
We aimed to develop prediction models for estimating the long-term survival in patients who have undergone surgery for esophageal cancer. ⋯ These models showed good performance for predicting long-term survival after esophageal cancer surgery and may thus be useful for patients in planning their lives and to guide the postoperative treatment and follow-up.
