Continent ileostomies: what the radiologist needs to know
AbstractContinent ileostomies are performed in patients who are not candidates for or do not want a traditionalJ-pouch after total colectomy. In these cases, patients may opt for a type of continent ileostomy instead of an end ileostomy. The most common types of continent ileostomies include the Kock (K) pouch,S-pouch and Barnett Continent Intestinal Reservoir. The normal fluoroscopic and CT appearance of these types of continent ileostomies are reviewed. CT provides better evaluation of the proximal small bowel and pouch for inflammatory bowel disease, while fluoroscopy is superior in evaluating the nipple valve. Common c...

Sonographic evaluation of a surgically created pouch
AbstractThis manuscript focuses on a review of the normal and abnormal sonographic appearance of the surgically created pouch as part of an article series on the topic. It includes information regarding sonographic technique, normal anatomy, and commonly encounter diseases and complications. (Source: Abdominal Imaging)

The anatomy and physiology of the ileal pouch and its relevance to pouch dysfunction
AbstractFor the last 40 years, the ileal pouch-anal anastomosis has been used in patients with ulcerative colitis, familial adenomatous polyposis, and occasionally severe constipation to reconstruct the gastrointestinal tract after proctocolectomy. Although the procedure has generally been successful in helping patients avoid an ileostomy, it has come with its own set of problems. These include complications of the surgery such as fistulas and bowel obstruction, persistent inflammation of the pouch known as pouchitis, and functional problems related to the lack of expulsive peristalsis in the pouch. It is this last group...

Key clinical trials in rectal cancer shaping the current treatment paradigms: reference guide for radiologists
AbstractTotal neoadjuvant therapy (TNT), which includes chemotherapy and radiation prior to surgical resection, has been recently accepted as the new standard of care for patients with locally advanced low and mid rectal cancers. Multiple clinical trials have evaluated this approach in the last several decades and demonstrated improvement in, local control and reduced risk of recurrence. In addition, in the course of these investigations, it has been shown that between a third and a half of patients experience a clinical complete response (cCR) after being treated with the TNT approach, leading to the development of new or...

Predicting successful ultrasound-guided biopsy of liver lesions
ConclusionsLinear logistic regression model that includes lesion size, depth and location, and number of lesions is highly successful in predicting feasibility of ultrasound-guided biopsy for liver lesions. Smaller lesions, deeper lesions, and lesions in segment II and VIII in patients with less than 3 lesions were less feasible for ultrasound-guided biopsy of liver lesions.Graphical abstract (Source: Abdominal Imaging)

Determination of prognostic predictors in patients with solitary hepatocellular carcinoma: histogram analysis of multiparametric MRI
ConclusionMultiparametric MRI-derived histogram parameters provide additional value in predicting patient prognosis. The CRH model may be a useful and noninvasive method for achieving prognostic stratification and personalized disease management. (Source: Abdominal Imaging)

Diagnostic performance of dynamic MR defecography in assessment of dyssynergic defecation
ConclusionMR defecography has high diagnostic performance in diagnosis of DD. Although M line and ARA at defecation are two significant findings on multivariate analysis, ARA change less than 1.5 degrees and prominent puborectalis muscle have good specificity in DD diagnosis.Graphical abstract (Source: Abdominal Imaging)

The adoption of LI-RADS: a survey of non-academic radiologists
ConclusionA majority of the non-academic radiologists surveyed use the LI-RADS CT/MR algorithm for HCC diagnosis, while nearly half use the LI-RADS TR algorithm for assessment of treatment response. Less than 10% of the participants routinely use the LI-RADS US and CEUS algorithms.Graphical abstract (Source: Abdominal Imaging)

Pelvic organ movements in asymptomatic nulliparous and symptomatic premenopausal women with pelvic organ prolapse in dynamic MRI: a feasibility study comparing midsagittal single-slice with multi-slice sequences
ConclusionMS sequences increase the visibility of organ points compared to SS sequences. Dynamic MS sequences can depict POP if images are acquired with sufficient straining effort. Further work is needed to optimize the depiction of the maximum straining effort with MS sequences.Graphical abstract (Source: Abdominal Imaging)
