Robotic surgery shows distinct advantages in protecting the pelvic autonomic nerves and relieving post-operative sexual dysfunction.

Colon 26 adenocarcinoma cells can induce severe cancer cachexia experimentally, and the mechanism may be partially due to the enhanced TNF-alpha and IL-6 in tumor-bearing animals, which is controlled by NF-kappaB. Low dose of indomethacin alleviates the cachexia, decreases the activation of NF-kappaB and the serum levels of TNF-alpha and IL-6, and prevents body weight loss and muscle atrophy, while no further effect is gained by a higher dosage.

Optimization of care in gastrectomy can shorten postoperative hospital stay and provides multiple beneficial outcomes, including hastening the return of gut function, without increasing morbidity.
