Transanal excision for T1 rectal tumors with low-grade malignancy has a high rate of recurrence. Although overall cancer survival rates might be regarded as satisfactory, this high recurrence and low salvage rate raises the issue about the role of transanal excision alone for early rectal cancer and the possible need for adjuvant therapy or increased role of resective surgery.

These findings implicate that use of EGF in gelatin-microsphere dressings improves wound healing both in normal and diabetic rats.

Based on the results, we conclude that phenol injection is as effective as the excision with open healing technique.

Closure of loop ileostomy is a simple procedure with low morbidity and a small but significant risk of mortality. Surgeons must consider the known risks in conjunction with the overall benefit/risk analysis before deciding between a temporary fecal diversion and a discontinuous colonic resection.

Deleterious effects of ischemia on left colonic anastomotic healing were significantly prevented by the administration of either 7 days' pretreatment with enteral guar gum or the intraluminal instillation of SCFAs. There were no significant differences between enteral and intraluminal SCFA groups.
