  • Anal Sphincteroplasty and Counter-Clockwise Gracilis Muscle Transposition by Using Transperineal Ischioanal Fossa Access in a Male Patient with Fecal Incontinence Who Undergone to Low Anterior Resection for Rectal Cancer
    Galenos Yayinevi, 2018
    Co-Authors: Ali Naki Yücesoy, Mehmet Çağlıkülekçi, Emre Sivrikoz
    Abstract:

    Fecal incontinence is a clinical condition that negatively affects the patient’s social and psychological life, and presents a surgical challenge due to dissatisfactory postoperative outcomes. Here we discuss the case of a 72-year-old male patient who underwent intersphincteric low anterior rectal resection for low rectal cancer one year earlier and developed complete fecal incontinence. We achieved good postoperative results in this patient by performing transperineal anal sphincteroplasty and counter-clockwise gracilis muscle transposition

  • sphincter saving extrasphincteric rectal dissection and proximal segmental sphincteric excision techniques by using combined abdominal and transvaginal anterior perineal access in female patients who have lower rectal cancer transvaginal low anterior
    Journal of Coloproctology, 2017
    Co-Authors: Ali Naki Yücesoy
    Abstract:

    Abstract Background Combined abdominal and transvaginal anterior perineal approaches have been used as an alternative surgical method for the surgical treatment of the lower rectal cancer. The main aim of this paper is to describe the surgical stages of the combined abdominal and transvaginal approaches performed for lower rectal cancer, especially in transvaginal anterior perineal stage. Method We have performed sphincter-saving surgical operations by using transvaginal anterior perineal access by combining with the abdominal access in four female patients who had lower rectal cancer. Results Sphincter-saving extrasphincteric dissection and proximal segmental sphincteric excision techniques were performed in four female patients operated with combined abdominal and transvaginal anterior perineal approach. All patients were found to have continence. Postoperatively, one patient was converted to abdominoperineal rectal amputation due to the detected distal resection margin positivity. Conclusion Transvaginal anterior perineal access provides the extrasphincteric rectal dissection possibility in the Ischioanal Fossa. Therefore, the combined abdominal and transvaginal anterior perineal approaches have been based on the different anatomical and surgical features when compared to intersphincteric dissection technique which is the most common used surgical procedure in lower rectal cancer surgery.

  • Is the Ischioanal Fossa the Most Appropriate Surgical Area for Fecal Incontinence Surgery?
    Galenos Yayinevi, 2017
    Co-Authors: Ali Naki Yücesoy
    Abstract:

    Fecal incontinence is the one of the surgical challenges faced by surgeons. Damage to the anal sphincter and neurological diseases are the major causes of fecal incontinence. Surgical interventions are especially necessary for reconstruction of the anal sphincter in patients with fecal incontinence patients due to anal sphincter damage. Surgical interventions performed for fecal incontinence can result in unsatisfactory postoperative outcomes, or initially satisfactory outcomes which deteriorate over time. We have performed surgical interventions with transvaginal access by combining the anal sphincteroplasty and gracilis transposition procedures in female patients who have anal sphincter damage subsequent to vaginal childbirth. The main aim of the transvaginal approach in our technique is to allow extrasphincteric dissection in the Ischioanal Fossa. As a result of our successful postoperative outcomes, this question came to our minds. Is the Ischioanal Fossa the most appropriate surgical area in fecal incontinence surgery

Resumo: Introdução: Uma combinação de abordagens abdominal e perineal anterior transvaginal tem sido empregada como método cirúrgico alternativo para o tratamento cirúrgico do câncer de reto baixo. O principal objetivo do presente artigo é a descrição dos estágios cirúrgicos das abordagens abdominal e transvaginal combinadas realizadas para câncer de reto baixo, especialmente no estágio perineal anterior transvaginal. Método: Realizamos operações cirúrgicas com preservação de esfíncter com o uso do acesso perineal anterior transvaginal, em combinação com o acesso abdominal, em quatro pacientes mulheres portadoras de câncer de reto baixo. Resultados: Realizamos técnicas de dissecção extra-esfincteriana e de excisão esfincteriana segmental proximal com preservação de esfíncter em quatro pacientes operadas com uma combinação de abordagens abdominal e perineal anterior transvaginal. Todas as pacientes estavam continentes. Em uma paciente, houve necessidade de conversão para amputação retal abdominoperineal, por ter sido detectada, no pós-operatório, positividade na margem de ressecção distal. Conclusão: O acesso perineal anterior transvaginal torna possível a dissecção retal extra-esfincteriana na Fossa isquioanal. Portanto, as abordagens combinadas abdominal e perineal anterior transvaginal se baseiam em diferentes características anatômicas e cirúrgicas, em comparação com a técnica de dissecção interesfincteriana, que é o procedimento cirúrgico de uso mais comum na cirurgia para câncer de reto baixo.

  • Ischiorectal Fossa: benign and malignant neoplasms of this “ignored” radiological anatomical space
    Abdominal Radiology, 2019
    Co-Authors: S. C. Faria, Sherif B. Elsherif, Tara Sagebiel, Chandana Lall, Priya R. Bhosale
    Abstract:

    Purpose To review the pertinent anatomy and the imaging features of common and uncommon benign and malignant neoplasms and masses of the ischiorectal Fossa. Results The ischiorectal or Ischioanal Fossa is the largest space in the anorectal region. The benign neoplasms that develop in the ischiorectal originate from the different components that forms the Fossa including vascular tumors such as aggressive angiomyxoma or hemangioma; neural tumors as plexiform neurofibroma or schwannoma; fat tumors as lipoma; skin/skin appendages tumors as hidradenoma papilliferum; smooth or skeletal muscle tumors as solitary fibrous tumor. The malignant neoplasms that develop in the ischiorectal Fossa also originate from different components that forms the Fossa including vascular tumors such as angiosarcoma, neural tumors as malignant granular cell tumor and malignant peripheral nerve sheath tumor; fat tumors as liposarcoma; smooth or skeletal muscle tumors as leiomyosarcoma, rhabdomyosarcoma, malignant PEComa, or undifferentiated pleomorphic sarcoma. Additionally, the ischiorectal Fossa can also harbor secondary hematogenous metastases and be affected by direct invasion from neoplasms of adjacent pelvic organs and structures. Furthermore, other miscellaneous masses can occur in the ischiorectal Fossa including congenital and developmental lesions, and inflammatory and infectious processes. Conclusion Knowledge of the anatomy, and the spectrum of imaging findings of common and uncommon benign and malignant neoplasms of the ischiorectal Fossa is crucial for the radiologists during interpretation of images allowing them to make contributions to the diagnosis and better patient management.

  • Pudendal nerve exposure and preservation in low rectal surgery by using transvaginal access
    Techniques in coloproctology, 2014
    Co-Authors: A. N. Yücesoy, S. Poçan, M. Cifçi, A. Solmaz, A. Serefhan
    Abstract:

    The pudendal nerves run with internal pudendal vessels, after arising from the ventral primary rami of S2, S3, and S4 bilaterally. They pass through Alcock’s canal, formed by the obturator fascia, and divide into rectal and urogenital terminal branches as neurovascular bundles. The pudendal nerves contain somatic and autonomic nerve fibers. Innervation of the external anal sphincters was mainly provided by the pudendal nerves. Our approach to pudendal nerve exposure and sparing in female patients undergoing transvaginal rectal surgery was as follows. We exposed the pudendal nerves below the levators by using transvaginal access in two female patients: one during ultralow rectal cancer resection and another one with fecal incontinence during sphincteroplasty and gracilis muscle transposition. After the rectovaginal septum was dissected (Fig. 1), the sublevator anal canal sphincter complex was mobilized (Figs. 2, 3). The pudendal nerves were exposed just below the levator muscle level at the posterolateral side of the Ischioanal Fossa (Fig. 4). Care was taken during surgery to identify the terminal branches of the pudendal nerves which course together with branches of the internal pudendal vessels (Figs. 5, 6).
