“…Nevertheless, EAUS can identify intersphincteric and transsphincteric fistulas, and internal fistula opening with high sensitivity and specificity, and results can be further improved with implementation of 3D-technique and hydrogen peroxide enhancement [ 17 , 18 ]. The latter may not be without risks as a case of hydrogen peroxide-induced proctitis after EAUS has recently been reported [ 19 ▪ ].…”

Purpose of reviewTo revise recent literature findings regarding the use of ultrasound in colonic and perianal diseases by focusing particularly on its feasibility in inflammatory bowel diseases (IBD), colorectal neoplastic lesions, and perineal diseases, with further highlight on interventional capabilities. Recent findingsTreat-to-target approach in IBD raised an interest in intestinal ultrasound (IUS) for monitoring bowel activity considering its noninvasive nature, low costs, and well tolerability. New IUS indices have been developed with ever better methodologies and are at various stage of validation. A standardized over-the-wire technique for colonic US using a flexible overtube enables endoscopic ultrasound (EUS)-guided tissue sampling beyond the rectum, and forward-viewing radial-array echoendoscopes can assist identification of early neoplastic lesions in proximal colon. Intraoperative ultrasound and contrast-enhanced ultrasound carry an additional diagnostic value compared to conventional preoperative imaging modalities in detecting colorectal cancer liver metastases (CRLM).

“…2 There were reported complications though rare like air embolism, proctitis and abdominal pain with H2O2 instillation into the fistula tract. 2,[5][6][7] Our study aims to evaluate the accuracy of unenhanced 3D-EAUS in the diagnosis of perianal fistula and abscess in comparison to the intraoperative surgical findings.…”

Background: Perianal sepsis which includes perianal fistula and abscess is a common clinical condition that requires thorough preoperative evaluation to decrease the recurrence rate and to plan relevant surgery according to the anatomy of the fistula. MRI and 3D EAUS are two important preoperative investigations that delineate the anatomy of simple and complex fistula tracts. Due to lower cost and easier use 3D EAUS is a safe and reliable first-line investigation in evaluating perianal abscess. Methods: This is a retrospective and prospective analysis of patients with perianal sepsis who underwent pre-operative unenhanced 3D-EAUS in the departments of Colorectal surgery, Gastrointestinal surgery, and General surgery in our hospital. A B-K medical 2052 transducer was used for the study and the surgical assessment was done by multiple surgeons from multiple departments. Results: A total of 255 patients were assessed. The accuracy for primary fistula tracts and internal opening was 83.53% and 88.62% respectively. The kappa coefficient of correlation was k=0.70 (substantial agreement) for the fistula tract and k=0.81 (near perfect agreement) for the internal opening. The sensitivity, and specificity of primary tracts and internal openings were calculated. Transphincteric fistulas were 57% in our study. Conclusions: Unenhanced 3D EAUS is a reliable first-line investigation in preoperative evaluation of perianal fistula and abscess. Transphincteric fistula is the most common type of fistula. There is a high chance of correlation for the primary tract if a non-colorectal specialist performs the fistula surgery after 3D-EAUS without blinding.
