Supplemental Perioperative Oxygen and the Risk of Surgical Wound Infection<SUBTITLE>A Randomized Controlled Trial</SUBTITLE>

ContextSupplemental perioperative oxygen has been variously reported to halve or double the risk of surgical wound infection.ObjectiveTo test the hypothesis that supplemental oxygen reduces infection risk in patients following colorectal surgery.Design, Setting, and PatientsA double-blind, randomized controlled trial of 300 patients aged 18 to 80 years who underwent elective colorectal surgery in 14 Spanish hospitals from March 1, 2003, to October 31, 2004. Wound infections were diagnosed by blinded investigators using Centers for Disease Control and Prevention criteria. Baseline patient characteristics, anesthetic treatment, and potential confounding factors were recorded.InterventionsPati…

[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…
