Background The enhanced recovery after surgery (ERAS) protocol for colorectal cancer resection recommends balanced perioperative fluid therapy. According to recent guidelines, zero-balance fluid therapy is recommended in low-risk patients, and immediate correction of low urine output during surgery is discouraged. However, several reports have indicated an association of intraoperative oliguria with postoperative acute kidney injury (AKI). We investigated the impact of intraoperative oliguria in the colorectal ERAS setting on the incidence of postoperative AKI.
Mammary duct ectasia is a rare disease in children and often presents as a cystic mass with bloody nipple discharge. The pathophysiology of mammary duct ectasia is unclear, and the differential diagnosis of other cystic masses with hemorrhage, such as complicated lymphangioma, is necessary. Here, we report a 14-month-old boy who exhibited unilateral mammary duct ectasia with bloody nipple discharge that was treated with surgical excision. Because some authors have reported that mammary duct ectasia can be often be resolved without surgery, conservative therapy should be considered first when a child presents with a cystic mass with bloody nipple discharge. However, the optimal duration of follow-up and timing of surgical excision have not yet been established.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
