The Contributions of Internal Intussusception, Irritable Bowel Syndrome, and Pelvic Floor Dyssynergia to Obstructed Defecation Syndrome.

Background: Recently, there has been a trend toward surgical management of internal intussusception despite an unclear correlation with constipation symptoms.

Objective: This study characterizes constipation in patients with obstructed defecation syndrome and identifies whether internal intussusception or other diagnoses such as irritable bowel syndrome may be contributing to symptoms.

Design: Patients evaluated for obstructed defecation at a pelvic floor disorder center were studied from a prospectively maintained database.

What Is the Risk of Anal Carcinoma in Patients With Anal Intraepithelial Neoplasia III?

Background: The risk of anal carcinoma after previous diagnosis of anal intraepithelial neoplasia III is unclear.

Objective: The purpose of this study was to estimate the risk of anal carcinoma in patients with anal intraepithelial neoplasia III and to identify predictors for subsequent malignancy.

Design: This was a retrospective review using the Surveillance, Epidemiology, and End Results registry (1973-2014).

Addition of a scripted pre-operative patient education module to an existing ERAS pathway further reduces length of stay.

Background: While enhanced recovery pathways (ERAS) appear to be beneficial for post-operative outcomes, there have been no studies evaluating the specific role of patient education within an ERAS pathway.

Methods: We identified all colectomies performed at our institution since initiation of an ERAS protocol, excluding for mortality and length of stay >30 days. Patients who received preoperative education by a nurse practitioner via a scripted telephone call were compared to patients who did not receive education using the NSQIP database.

Pudendal nerve terminal motor latency testing does not provide useful information in guiding therapy for fecal incontinence.

Purpose: Pudendal nerve terminal motor latency (PNTML) testing is a standard recommendation for the evaluation of fecal incontinence. Its role in guiding therapy for fecal incontinence has been previously questioned. The aim of this study was to evaluate the relationship between PNTML testing and anorectal dysfunction.

Effect of disease progression on liver apparent diffusion coefficient values in a murine model of NASH at 11.7 Tesla MRI.

Purpose: To evaluate the apparent diffusion coefficient (ADC) values of liver in a murine model of non-alcoholic steatohepatitis using 11.7 Tesla (T) MRI.

Materials And Methods: This animal study was IACUC approved.

Influence of body habitus and use of oral contrast on reader confidence in patients with suspected acute appendicitis using 64 MDCT.

The purpose of this study is to evaluate how body habitus affects reader confidence in diagnosing acute appendicitis and appendiceal visualization using 64 MDCT technology with and without oral contrast. We conducted a HIPAA compliant, IRB approved study of adult patients presenting to the Emergency Department with nontraumatic abdominal pain. Subjects were randomized to two groups: 64 MDCT scans performed with oral and intravenous contrast or scans performed solely with intravenous contrast.
