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.

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.

Complete excision of sarcomas to maximize function without compromising the oncological outcome can be challenging. The aim of this study was to investigate the feasibility and potential drawbacks of near-infrared (NIR) fluorescence imaging with indocyanine green during resection of bone and soft tissue sarcomas. ⋯ This is the first report of NIR fluorescence guidance in the setting of open sarcoma surgery. The technique is acceptable to patients and surgeons and was able to guide resection. Multicenter studies are required to assess the utility of this technique in a large cohort of patients with regards to quantification of fluorescence, resection guidance, and longer follow-up period.

To identify predictive factors associated with operative morbidity, mortality, and survival outcomes in patients with borderline resectable (BR) or locally advanced (LA) pancreatic ductal adenocarcinoma (PDAC) undergoing total neoadjuvant therapy (TNT). ⋯ Our TNT experience in resected BR/LA PDAC revealed high negative margin rates despite low radiologic downstaging. Extended duration chemotherapy with associated biochemical and pathologic responses highly predicted postoperative survival. Potential modifications of initial chemotherapy treatment include extending cycle duration to normalize CA19-9 or achieve complete metabolic response, or consideration of chemotherapeutic switch in order to achieve these factors may improve survival before moving forward with CRT and subsequent resection.
