To investigate the prevalence and risk factors for chronic abdominal pain after Roux-en-Y gastric bypass (RYGB) surgery. ⋯ One in 10 patients undergoing RYGB surgery developed chronic abdominal pain requiring strong analgesics, and one in five suffered from severe abdominal pain. Risk factors were preoperative use of strong analgesics, unemployment, postoperative complications, and smoking.

Aim of this prospective study was to evaluate the prognostic significance of disseminated tumor cells (DTCs) and circulating tumor cells (CTCs) in 1 cohort of patients with esophageal cancer (EC). ⋯ This is the first study analyzing CTC and DTC status in 1 cohort of nonmetastatic patients with EC. In this early disease stage, only the CTC status was an independent, prognostic marker suitable and easy to use for clinical staging of patients with EC.
-
To define long-term outcome, predictors of survival, and risk of disease recurrence after gut transplantation (GT) in patients with chronic intestinal pseudo-obstruction (CIPO). ⋯ GT is life-saving for patients with end-stage CIPO and HPN-associated complications. Long-term survival is achievable with better quality of life and low risk of disease recurrence.
-
To determine the effect of a previously unassessed measure of quality-preventable hospitalization rate-on mortality after oncologic surgery for 4 procedures with established volume-outcome relationships. We hypothesize that hospitals with higher preventable hospitalization rates (indicating poor quality of primary care) have increased hospital mortality. Additionally, patients having surgery at hospitals with higher preventable hospitalization rates have increased mortality. ⋯ Preventable hospitalization rates could serve as warning signs of low quality of care and be a publically-reported quality measure.

Observational Study
A National Comparison of Operative Outcomes of New and Experienced Surgeons.
To determine whether outcomes achieved by new surgeons are attributable to inexperience or to differences in the context in which care is delivered and patient complexity. ⋯ Among Medicare beneficiaries, the majority of the differences in outcomes between new and experienced surgeons are related to the context in which care is delivered and patient complexity rather than new surgeon inexperience.
