In screening, artificial intelligence-enhanced colonoscopy increases adenoma detection rates from 40.4% to 54.8% ( p < 0.001) in multicenter trials, with cross-validation on colonoscopy images demonstrating 96.4% polyp detection accuracy. Diagnostic applications include microsatellite instability prediction from histology and automated MRI tumor segmentation. Preoperatively, machine learning models predict mortality and morbidity, outperforming traditional risk measures such as the American Society of Anesthesiologists classification and the American College of Surgeon-National Surgical Quality Improvement Program. Intraoperatively, artificial intelligence has demonstrated early feasibility for real-time tissue plane, artificial intelligence-based automated perfusion assessment can predict anastomotic viability, and artificial intelligence can enable identification of critical structures such as pelvic nerves. Postoperatively, artificial intelligence is starting to detect complications hours before clinical diagnosis, reducing documentation time.

Multivariable regression was used to evaluate associations between sexual distress and operative factors, age, sex, income, education, ethnicity, sexual orientation, and relationship status.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Of 1830 eligible patients, 497 responded and were included in the analysis. Overall, 194 patients (39%) screened positive for sexual distress. Women were disproportionately affected, with more than half reporting clinically significant distress (141/243; 57.8%). Female gender was the only independent preoperative predictor of sexual distress on multivariable analysis (OR 4.796; 95% CI, 3.119-7.374; p &lt; 0.001). Poor bowel function, anxiety, and depression were all significantly more prevalent among patients with sexual distress (all p &lt; 0.001).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Limitations: &lt;/strong&gt;Cross-sectional design limits causal inference. Selection and response bias are possible.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;Sexual distress is common after pelvic pouch surgery for ulcerative colitis, particularly among women, and is strongly associated with bowel dysfunction, anxiety, and depression. These findings highlight the importance of holistic preoperative and postoperative counseling and the consideration of psychological screening in follow-up care. Further research is needed to elucidate underlying mechanisms and develop targeted interventions.
