- BACKGROUND: Reports of esophageal anastomotic complications often involve more gastric than colonic reconstructions and are incomplete because of fragmented followup by physicians unfamiliar with the surgical procedure. STUDY DESIGN: Three hundred ninety-three consecutive esophagectomy patients had prevalence and risk factors determined for graft ischemia and anastomotic leak; 363 of these patients followed for more than I month (median 15 months) had prevalence and risk factors determined for anastomotic stricture. RESULTS: Conduit ischemia occurred in 36 (9.2%) and anastomotic leak in 43 patients (10.9%). Risk factor for ischemia was comorbid conditions requiring therapy (Odds ratio [OR]: 2.2 [95% CI 1.1-4.3]), and for leak were ischemia (OR: 5.5 [95% CI 2.5-12. 1]), neoadjuvant therapy (OR: 2.2 [95% CI 1.1-4-5]), and comorbid conditions (OR: 2.1 [95% Cl 1.1-3.9]). A stricture developed in 80 patients (22.0%). Risk factors were ischemia (OR: 4.4 [95% Cl 2.0-9.6]), anastomotic leak (OR: 3.8 [95% C11.9-7.6]), and increasing preoperative weight (p = 0.022). The prevalence of ischemia was similar after gastric (10.4%) versus colonic (7.4%) reconstruction; leak and stricture were more common (14.3% versus 6.1%, p = 0.013, 31.3% versus 8.7%, p < 0.000 1, respectively) and strictures were more severe (11.2% versus 2%, p = 0.00 1) after gastric pull-up. Patients free of ischemia and leak who developed stricture were more likely to have had a gastric pull-up (25% versus 7%, p < 0. 000 1). Dilatation was effective treatment in 93% of patients. CONCLUSIONS: After esophagectomy 10% of patients will develop conduit ischemia or an anastomotic leak and 22% will develop anastornotic stricture. Anastomotic leak and strictures are more common and the strictures are more severe after gastric pull-up compared with colon interposition. Dilatation is a safe and effective treatment.

- This report documents the outcomes of a professional development workshop (PDW) held at the 40th International Conference on Information Systems in Munich, Germany. The workshop focused on identifying how information systems (IS) researchers can contribute to enriching our knowledge about digital entrepreneurship-that is, the point at which digital technologies and entrepreneurship intersect. The PDW assembled numerous IS researchers working on different aspects of digital entrepreneurship. Jointly, we delineated digital entrepreneurship from related phenomena and conceptualized the different roles that digital technologies can have in entrepreneurial endeavors. We also identified relevant strategies, opportunities, and challenges in conducting digital entrepreneurship research. This report summarizes the shared views that emerged from the interactions at the PDW and our collaborative effort to write this report. The report provides IS researchers interested in digital entrepreneurship with food for thought and a foundation for future research.
