“…It is difficult to differentiate between benign and malignant lymph nodes using ERUS 35 , even for experienced users. Moderate sensitivities (57–73%) and specificities (76–80%) have been reported by several meta-analyses 26 36 37 38 . However, none of the currently available imaging methods (MRI and CT) can provide more reliable information on lymph node status 38 .…”

“…Studies available from the literature have reported very good performance of ERUS regarding the pre-therapeutic assessment of the depth of tumor invasion, with sensitivities and specificities ranging between 80–96%, and 80–98%, respectively, as shown by meta-analyses 25 26 . ERUS is the best documented examination for classifying early rectal lesions 27 , either confined to the mucosa (sensitivity and specificity ~ 97%) which may be referred for endoscopic resection ( Fig.…”

This article represents part 3 of the EFSUMB Recommendations and Guidelines for Gastrointestinal Ultrasound (GIUS). It provides an overview of the examination techniques recommended by experts in the field of endorectal/endoanal ultrasound (ERUS/EAUS), as well as perineal ultrasound (PNUS). The most important indications are rectal tumors and inflammatory diseases like fistula and abscesses in patients with or without inflammatory bowel disease (IBD). PNUS sometimes is more flexible and convenient compared to ERUS. However, the technique of ERUS is quite well established, especially for the staging of rectal cancer. EAUS also gained ground in the evaluation of perianal diseases like fistulas, abscesses and incontinence. For the staging of perirectal tumors, the use of PNUS in addition to conventional ERUS could be recommended. For the staging of anal carcinomas, PNUS can be a good option because of the higher resolution. Both ERUS and PNUS are considered excellent guidance methods for invasive interventions, such as the drainage of fluids or targeted biopsy of tissue lesions. For abscess detection and evaluation, contrast-enhanced ultrasound (CEUS) also helps in therapy planning.

“…However, the implementation of abdominal computed tomography (CT) scan showed clear images of the local spread of distal rectal cancer, where the exact relation between the tumor and surrounding organ used to be unclear [ 4 ]. The endorectal ultrasonographic evaluation was later available, easy to use, and helpful to assess the depth of invasion [ 5 ]. However, its use was limited and operator-dependent, and in some cases, not able to evaluate the complete extension of the tumor above the anal sphincter and levator ani complex.…”

Despite innovative advancements, distally located rectal cancer remains a critical disease of challenging management. The crucial location of the tumor predisposes it to a circumferential resection margin (CRM) that tends to involve the anal sphincter complex and surrounding organs, with a high incidence of delayed anastomotic complications and the risk of the pelvic sidewall or rarely inguinal lymph node metastases. In this regard, colorectal surgeons should be aware of other issues beyond total mesorectal excision (TME) performance. For decades, the concept of extralevator abdominoperineal resection to avoid compromised CRM has been introduced. However, the complexity of deep pelvic dissection with poor visualization in low-lying rectal cancer has led to transanal TME. In contrast, neoadjuvant chemoradiotherapy (NCRT) has allowed for the execution of more sphincter-saving procedures without oncologic compromise. Significant tumor regression after NCRT and complete pathologic response also permit applying the watch-and-wait protocol in some cases, now with more solid evidence. This review article will introduce the current surgical treatment options, their indication and technical details, and recent oncologic and functional outcomes. Lastly, the novel characteristics of distal rectal cancer, such as pelvic sidewall and inguinal lymph node metastases, will be discussed along with its tailored and individualized treatment approach.

“…Apesar do ultrassom ser capaz de determinar características sugestivas de malignidade, como formato arredondado, localização peritumoral, tamanho (> 5 mm) e hipoecogenicidade heterogênea, esses fatores parecem não ser suficientemente sensíveis ou específicos para o diagnóstico correlato de malignidade com o espécime cirúrgico (50,57,58) .
