TRUS-guided brachytherapy permits excellent local tumor control and results in minimal treatment-related morbidity. Consequently, TRUS-guided brachytherapy may be a useful addition to current combined modality treatment regimens for anal cancer.
Endorectal ultrasound is a useful, noninvasive technique for preoperative evaluation of possible rectal wall involvement in endometriosis. Based on the high sensitivity and specificity, recommendation for laparotomy and bowel resection in cases with suspected rectal involvement can be facilitated.
Preoperative endorectal ultrasound is a reliable technique to visualize perirectal endometriomas and to assess rectal wall involvement. Based on preoperative endosonographic diagnosis, an operative management was established with laparotomy and resection of the affected bowel in cases of rectal wall involvement.
Postoperative endoluminal ultrasound is able to detect local recurrence at an earlier and asymptomatic stage and can be verified by endosonography-guided needle biopsy. Routine use in follow-up may raise the ratio of curative retreatment by early detection of extramural local recurrence.
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.
