Item Capsule endoscopy of the small bowel and esophagus: current technology, indications, and clinical relevance(2005-09-01) Ulrich, Charles D.Item The disclosure dilemma: when adverse events affect multiple patients(2015-01-13) Dudzinski, Denise M.Imagine that endoscopes had not been properly processed for a period of several months. Once discovered, the problem is immediately corrected, but patients scoped during those months are more likely to even though the majority are unlikely to have been harmed? This presentation will explore the ethical and practical dimensions of this question by examining several cases.Item Endoscopic approaches to the patient with UGI hemorrhage(1980-02-21) Peterson, Walter L.Item Endoscopic therapies for weight loss: current and future paradigms(2023-09-08) Shah, ShawnItem Prognostic Value of Surgical Margins During Endoscopic Resection of Paranasal Sinus Malignancy(2014-02-04) Manjunath, Lakshman; Derousseau, Taylor; Batra, Pete S.BACKGROUND: Complete tumor resection with intraoperative frozen section control remains a central tenet of head and neck surgical oncology. The purpose of the present study was evaluate the significance of margins in predicting local recurrence and disease status following endoscopic resection of sinonasal cancer. METHODS: This single-institution observational cohort study was performed on 68 patients over a 5-year period that underwent curative minimally invasive endoscopic resection (MIER) for sinonasal malignancies. RESULTS: The mean age was 58.8 years and 69.1% were male. The mean follow-up after definitive MIER was 15.9 months. A mean of 10.8 margins were taken per surgery (range 2 - 27). False negative frozen section analysis was 22.1% for the entire cohort, being slightly higher at 25.0% for T3 or T4 malignancies. At the last follow-up, no evidence of disease (NED) status was noted in 60.0% of those with positive margins versus 83.0% in those with negative margins, respectively (p = 0.0795). Regional or distant recurrences were observed in 39.9% of patients with positive margins and 13.2% of those with negative margins, respectively. Disease free survival (DFS) was 9.7 months for patients with positive margins, whereas those with negative margins had a DFS of 15.9 months. CONCLUSION: Statistical significance could not be achieved regarding the prognostic value of margin status on patient outcome. However, NED status as a function of residual microscopic disease proved to be marginally significant. These results suggest that complete resection with clear margins may reduce mortality in patients undergoing MIER for cancers of the paranasal sinuses.Item Selected vignettes or the emerging role of endoscopic therapy in pancreatic disease(1990-04-19) McCarthy, JustinItem [Southwestern News](1999-10-27) Manley, Jennifer HaighItem [UT News](1986-11-17) West, Mike
