Sphincter damage during fistulotomy for perianal fistulae and its relationship with faecal incontinence.

Abstract Background The length of sphincter which can be divided during fistulotomy for perianal fistula is unclear. The aim was to quantify sphincter damage during fistulotomy and determine the relationship between such damage with symptoms and severity of faecal incontinence and long-term quality of life (QOL). Methods A prospective cohort study was performed over a 2-year period. Patients with intersphincteric and mid to low transsphincteric perianal fistulas without risk factors for faecal incontinence were scheduled for fistulotomy. All patients underwent 3D endoanal ultrasound (3D-EAUS) pre-operatively and 8 weeks postoperatively. Measurements were taken of pre- and postoperative anal…

[Evaluation of three-dimensional endoanal endosonography of perianal fistulas and correlation with surgical findings].

Abstract Objective This study aims to assess the accuracy of three-dimensional endoanal ultrasound (3D-US), two-dimensional ultrasound (2D-US) and physical examination (PE) for the diagnosis of perianal fistulas and correlate the results with intraoperative findings. Materials and methods A prospective, observational study with consecutive inclusion of patients was performed between December 2008 and August 2009. Twenty-nine patients diagnosed with a perianal fistula due to undergo surgery were included. All patients underwent PE, 2D-US and 3D-US, and the results were compared to intraoperative findings. The examinations were repeated with hydrogen peroxide instilled through the external op…

Concordance and survival implications of preoperative subclassification of T3 rectal cancers by depth of mesorectal invasion using a 5-mm cut-off point with endorectal ultrasound and magnetic resonance imaging.

BACKGROUND: Validated rectal cancer staging groups T3 tumours in a single stage and depth of mesorectal invasion subclassification is not standard practice. Our aim is to report concordance between magnetic resonance imaging (MRI) and endorectal ultrasound (ERUS) for preoperative staging of T3 rectal tumours using a 5-mm cut-off point and possible survival implications. METHODS: Prospective cohort study including patients staged preoperatively as cT3 by ERUS or magnetic resonance imaging. The maximum depth of penetration beyond the outer longitudinal muscle layer was measured according to a 5-mm cut-off point. Concordance rate and Kappa coefficient were calculated for both techniques. Prima…

Evaluación de las fístulas perianales mediante ecografía endoanal tridimensional y correlación con los hallazgos intraoperatorios

Resumen Objetivo Evaluar la fiabilidad diagnostica de la ecografia tridimensional (ECO 3D) vs. la bidimensional (ECO 2D) y la exploracion fisica en el diagnostico de las fistulas perianales correlacionandolo con los hallazgos intraoperatorios. Material y metodo Estudio prospectivo, observacional con pacientes incluidos de forma consecutiva entre diciembre 2008 y agosto 2009. Se incluyen 29 pacientes diagnosticados de fistula perianal subsidiarios de tratamiento quirurgico. Se realizo una exploracion fisica, ECO 2D, ECO 3D comparandolos con los hallazgos intraoperatorios. Cuando el orificio fistuloso externo se encuentra abierto, se repiten ambas exploraciones instilando agua oxigenada. Resu…
