Anatomical Variation of Abdominal Wall Musculature: An Objective Assessment Using Cross-Sectional Imaging.

To determine normal anatomical variation of abdominal wall musculature. A retrospective analysis of CT scans was performed on adults (>18 years) with normal abdominal wall muscles. Two radiologists analysed the images independently.

A Ventral Hernia Management Pathway; A "Getting It Right First Time" approach to Complex Abdominal Wall Reconstruction.

Introduction: Abdominal wall reconstruction (AWR) is an emerging specialty, involving complex multi-stage operations in patients with high medical and surgical risk. At our hospital, we have developed a growing interest in AWR, with a commitment to improving outcomes through a regular complex hernia MDT. An MDT approach to these patients is increasingly recognized as the path forward in management to optimize patients and improve outcomes.

Accuracy of Four Imaging Techniques for Diagnosis of Posterior Pelvic Floor Disorders.

Objective: To establish the diagnostic test accuracy of evacuation proctography, magnetic resonance imaging (MRI), transperineal ultrasonography, and endovaginal ultrasonography for detecting posterior pelvic floor disorders (rectocele, enterocele, intussusception, and anismus) in women with obstructed defecation syndrome and secondarily to identify the most patient-friendly imaging technique.

Methods: In this prospective cohort study, 131 women with symptoms of obstructed defecation syndrome underwent evacuation proctogram, MRI, and transperineal and endovaginal ultrasonography. Images were analyzed by two blinded observers.

Local staging and assessment of colon cancer with 1.5-T magnetic resonance imaging.

Objective:: The aim of this study was to assess the accuracy of 1.5-T MRI in the pre-operative local T and N staging of colon cancer and identification of extramural vascular invasion (EMVI).

Methods:: Between 2010 and 2012, 60 patients with adenocarcinoma of the colon were prospectively recruited at 2 centres.

Perfusion CT vascular parameters do not correlate with immunohistochemically derived microvessel density count in colorectal tumors.

Purpose: To determine whether perfusion computed tomography (CT)-derived vascular parameters-namely, blood flow, mean transit time (MTT), volume transfer constant (K(trans)), permeability-surface area product (PS), extracellular extravascular space volume, and vascular volume-correlate with the immunohistologic markers of angiogenesis in colorectal tumors.

Materials And Methods: This prospective study was approved by the Regional Ethics and Research and Development Committees. The perfusion CT protocol was incorporated in the staging CT after informed consent in 29 patients (14 men, 15 women; mean age, 70 years; age range, 55-94 years).
