Ultrasonography of imperforate Anus in neonate: an approach correlated with current surgical concepts.
Ultraschall in Der Medizin, 2008Co-Authors: Hans P. HaberAbstract:Neonates with an imperforate Anus pose a challenge to those responsible for diagnosing and treating the congenital abnormality. Early assessment and accurate diagnosis of the type of imperforate Anus are essential for determining the appropriate surgical procedure. Transperineal ultrasonography (US) can be used to identify the internal fistula and to define the type of imperforate Anus. Thus, US represents an useful noninvasive imaging modality for assisting in the diagnosis and appropriate management of this disease. We will describe this imaging technique and present different types of illustrative scans of an imperforate Anus.

Transperineal sonography of the anal sphincter complex in neonates and infants: differentiation of anteriorly displaced Anus from low-type imperforate Anus with perineal fistula.
Ultraschall in Der Medizin, 2008Co-Authors: Hans P. Haber, S W Warmann, J FuchsAbstract:PURPOSE: To evaluate the usefulness of transperineal sonography of the anal sphincter complex for differentiating between an anteriorly displaced Anus, which is a normal anatomical variant, and a low-type imperforate Anus with perineal fistula, which is a pathological developmental abnormality requiring surgical repair. MATERIALS AND METHODS: Transperineal sonography was performed with a 13-MHz linear-array transducer on 8 infants (1 day - 5.3 months old) who were considered on clinical grounds to have an anteriorly displaced Anus and on 9 infants (0 - 8 months old) with a low-type imperforate Anus and perineal fistula confirmed at surgery. The anal sphincter complex was identified and the relationship between the anal canal and the anal sphincter complex was evaluated. RESULTS: Transperineal sonography was feasible for all children without any specific preparation. An anal canal running within an intact sphincter complex was identified in all infants with an anteriorly displaced Anus (n = 8). In 8 of 9 infants with a low-type imperforate Anus, a perineal fistula running outside the anal sphincter complex was correctly diagnosed by transperineal sonography. In one infant with a low-type imperforate Anus, transperineal sonography revealed a deficient anal sphincter complex. CONCLUSION: Transperineal sonography appears to be a useful non-invasive imaging technique for assessing congenital anorectal abnormalities in neonates and infants, allowing the surgeon to select infants who would benefit from surgical repair.

Transperineal Sonography for Determination of the Type of Imperforate Anus
AJR. American journal of roentgenology, 2007Co-Authors: Hans P. Haber, Guido Seitz, Steven W. Warmann, Jörg FuchsAbstract:OBJECTIVE. The purpose of this study was to assess whether transperineal sonography is valid and accurate for discriminating the low (translevator) type of imperforate Anus from the intermediate and high (supralevator) types. The distinction is critical in determination of the surgical approach.MATERIALS AND METHODS. Fifty-six consecutively enrolled infants (0–90 days old) with imperforate Anus underwent transperineal gray-scale sonography with a 12-MHz linear array transducer. The distance between the distal rectal pouch and the perineum was measured, and a cutoff distance for differentiating types of imperforate Anus was identified. The sonographic findings were compared with the final diagnosis reached with radiographic and surgical findings.RESULTS. Transperineal sonography was feasible in all children without specific preparation. The mean distance between the distal rectal pouch and the perineum in the 22 infants with low imperforate Anus was 10 ± 4 (SD) mm compared with a mean of 24 ± 6 mm in the 3...

Anus-protective operation for the aged patients with low rectal carcinoma
Journal of Modern Oncology, 2005Co-Authors: Zhang Zhao-huAbstract:Objective To explore the feasibility of Anus -protective operations for the aged patients with low rectal carcinoma. Methods The clinical data of 47 cases with low rectal carcinoma whose affected rectum was 7 cm from the edge of Anus were collected. Among them 11 cases lowest affected part was 3～5 cm from the edge of Anus and 36 cases 5～7 cm from Anus. And 10 cases were in Dukes stage A, 32 cases were in Dukes stage B and 5 cases were in Dukes stage C, 38 cases were treated with Dixon operation, 5 with Parks operation and 4 with Bacon operation. The local recurrence rate and survival rate of the above operations were compared with those of the Miles operations on 68 patients with rectal carcinoma. Results The local recurrence rate of Anus-protective operation and 3-year, 5-year survival rates were 17.1%, 65.9% and 59.6% respectively, while those of Miles operations were 16. 2%、67.6% and 51.5% respectively( P0.05). Conclusion Anus-protective operation provides effective treatment for low rectal carcinoma with a satisfactory long term survival rate and quality of life.
