The Extraperitoneal Approach to Left-Sided Colorectal Rectal Resections: EXPERTS Procedure.

Background: Current transperitoneal approaches to colorectal resections can be technically challenging, especially in obese patients. The head-down position can lead to rare but serious complications, e.g.

The Extraperitoneal Approach to Left-Sided Colorectal Resections: A Human Cadaveric Study.

Introduction: Technical challenges during laparoscopic and robotic anterior resection include identification of key retroperitoneal structures and obtaining clear views of the inferior mesenteric artery (IMA) pedicle and total mesorectal excision (TME) plane. Steep head-down position improves surgical exposure but is associated with cerebral oedema, high intrapulmonary pressures, and rare neurological complications. In this article we describe the key steps of an anterior resection performed via the extra-peritoneal (XP) space in the supine position.

Creation of a synthesis-friendly inflammation-inducible promoter suitable for cell therapy.

The development of 'smart' cell-based therapeutics requires cells that first recognize conditions consistent with disease (e.g. inflammation) and then subsequently release therapeutic proteins, thereby reducing potential toxicity from otherwise continuous expression.

Generation of stable cell lines using readthrough expression from lentiviral integration.

Lentiviral infection is often used to integrate genetic material into cells to stably express transgenes of interest. Depending on the location of integration into the host genome, readthrough expression of the lentiviral cargo can occur via an upstream endogenous promoter, which is typically an unwanted phenomenon because it can result in dysfunctional expression. The purpose of this study was to demonstrate that readthrough expression can be a wanted phenomenon for expressing functional proteins while at the same time reducing the size of the lentiviral transfer plasmid.

Resource implications of running a sacral neuromodulation service: a 10-year experience.

Aim: In this study we reviewed our 10-year experience of the medium- to long-term success of sacral nerve stimulation (SNS) for faecal incontinence, with particular reference to the resource implications of running such a service.

Method: All patients treated with permanent SNS implants for faecal incontinence from 2001 to 2012 were identified from a prospective database. The patients underwent follow up at 3 and 6 months, with annual review thereafter.

The association between prucalopride efficacy and constipation type.

Background: Prucalopride is a selective serotonin receptor agonist with prokinetic activity, indicated for women with chronic constipation in whom laxatives have failed to provide adequate relief. Data suggests an improvement in about 50 % of such patients but whether the therapeutic effect is on patients with slow transit constipation (STC) and/or obstructed defaecation syndrome (ODS), or even those with constipation-predominant irritable bowel syndrome (IBS-C) is unknown. We therefore assessed whether there is any association between prucalopride efficacy and constipation type.

Does sacral nerve stimulation improve global pelvic function in women?

Aim: Many women undergoing sacral neuromodulation for faecal incontinence have coexisting pelvic floor dysfunction. We used a global pelvic-floor assessment questionnaire to evaluate the effect of sacral neuromodulation on non-bowel related symptomatology.

Method: The electronic Personnel Assessment Questionnaire - Pelvic Floor (ePAQ-PF) is a validated Web-based electronic pelvic floor questionnaire.

Metachronous bilateral adrenal metastases following curative treatment for colorectal carcinoma.

A delayed, metachronous presentation of bilateral adrenal metastases following colorectal cancer has never previously been reported. We describe the case of a 68-year-old man who underwent curative surgery and adjuvant chemotherapy for a locally invasive sigmoid adenocarcinoma, only to be diagnosed with metachronous bilateral adrenal metastasis necessitating further resection and chemotherapy. We discuss the literature surrounding this pathology and highlight the importance of continual, vigilant radiological surveillance of the adrenal glands after curative treatment of colorectal carcinoma with or without subsequent adrenal metastasis.

Solitary colonic metastasis from renal cell carcinoma presenting as a surgical emergency nine years post-nephrectomy.

Late colonic metastasis following curative surgery for renal cell carcinoma has rarely been described. We present the first reported case of solitary colonic renal cell carcinoma metastasis presenting as an intra-abdominal bleed, nine years post-nephrectomy.

Quantitative dimensions of histopathological attributes and status of GSTM1-GSTT1 in oral submucous fibrosis.

Oral submucous fibrosis (OSF) is a precancerous condition of the oral cavity and oropharynx and a significant number of such cases transform into oral squamous cell carcinoma (OSCC). Presently, diagnosis of OSF is done mainly through qualitative histopathological techniques and in the level of diagnostic molecular biology no specific genetic marker is evident. Keeping these facts in mind this study evaluates histopathological changes in the epithelium and subepithelial connective tissue of OSF through quantitative digital image analysis in respect to specific candidate features and analyses null mutations in the GSTM1 and GSTT1 by PCR amplification.
