Surgeons have experienced an increase in the number of patients referred for management endoscopically unresectable colon polyps as a result increased adoption colonoscopy-based cancer screening. The majority these historically received recommendation to undergo oncologic resection, exposing them significant operative and long-term morbidity. Combined endoscopic laparoscopic surgery (CELS) techniques since been developed leverage unique advantages two separate approaches allow colon-sparing...

For stage II/III rectal cancer patients, comprehensive multidisciplinary care (MDC) affects outcomes. Randomized trials have shown the effectiveness of adjuvant and neoadjuvant therapy in treatment these patients. However, collaboration within MDC is undetermined. It possible that regional variation survival outcomes may be tied to facility. We retrospectively reviewed a prospectively collected database patients with who received at any location underwent oncologic colorectal resection...

A major problem with using automated classification systems is that if they are not engineered correctly and fairness considerations, could be detrimental to certain populations. Furthermore, while engineers have developed cutting-edge technologies for image classification, there still a gap in the application of these models human heritage collections, where data sets usually consist low-quality pictures people diverse ethnicity, gender, age. In this work, we evaluate three bias mitigation...

BACKGROUND: Benign colon polyps are increasingly being detected because of improved colonoscopic screening and early detection masses on the adenoma-to-carcinoma pathway. Full-thickness laparoendoscopic excision is a colon-preserving technique for endoscopically unresectable consisting guided nonanatomic wedge colectomy. OBJECTIVE: This study aimed to evaluate safety success full-thickness compared segmental colectomy complex not amenable endoscopic resection. DESIGN: retrospective...
