This article is the second in a series of two publications relating to European Crohn's and Colitis Organisation [ECCO] evidence-based consensus on management disease. The first covers medical management; present addresses surgical management, including preoperative aspects drug before surgery. It also provides technical advice for variety common clinical situations. Both articles together represent recommendations ECCO disease an update previous guidelines.
This study aims to report short-term clinical and oncological outcomes from the international transanal Total Mesorectal Excision (taTME) registry for benign malignant rectal pathology.TaTME is latest minimally invasive technique pioneered facilitate difficult pelvic dissections. Outcomes have been published small cohorts, but larger series can further assess safety efficacy of taTME in wider surgical population.Data were analyzed 66 registered units 23 countries. The primary endpoint was...
The goal of this consensus initiated by the European Crohn's and Colitis Organisation (ECCO) was to establish guidelines for surgical treatment ulcerative colitis. strategy reach involved several steps follows standard operating procedures ECCO. An open call chairs participants made (see acknowledgements www.ecco-ibd). Participants were selected Guidelines' Committee ECCO (GuiCom) on basis their publication record a personal statement. Four working groups (WGs) formed: WG 1 preoperative...
Objective: To determine the incidence of anastomotic-related morbidity following Transanal Total Mesorectal Excision (TaTME) and identify independent risk factors for failure. Background: Anastomotic leak its sequelae are dreaded complications gastrointestinal surgery. TaTME is a recent technique rectal resection, which includes novel anastomotic techniques. Methods: Prospective study consecutive reconstructed cases recorded over 30 months in 107 surgical centers across 29 countries. Primary...
Objectives: This study provides an overview of the largest and longest-running colonoscopic surveillance program for colorectal cancer (CRC) in patients with long-standing ulcerative colitis (UC). Methods: Data were obtained from medical records, endoscopy, histology reports. Primary end points defined as death, colectomy, withdrawal surveillance, or censor date (1 January 2013). Results: A total 1,375 UC followed up 15,234 patient-years (median, 11 years per patient). CRC was detected 72...

Objective Ulcerative colitis (UC) is a dynamic disease with its severity continuously changing over time. We hypothesised that the risk of colorectal neoplasia (CRN) in UC closely follows an actuarial accumulative inflammatory burden, which inadequately represented by current stratification strategies. Design This was retrospective single-centre study. Patients extensive who were under colonoscopic surveillance between 2003 and 2012 studied. Each episode scored for microscopic inflammation...
OBJECTIVES: The aim of this study was to identify risk factors associated with development high-grade dysplasia (HGD) or colorectal cancer (CRC) in ulcerative colitis (UC) patients diagnosed low-grade (LGD). METHODS: Patients histologically confirmed extensive UC, who were LGD between 1993 and 2012 at St Mark's Hospital, identified followed up 1 July 2013. Demographic, endoscopic, histological data collected correlated the HGD CRC. RESULTS: A total 172 for a median 48 months from date...
Intra-abdominal septic complications [IASC] following ileocolonic resection for Crohn's disease are common. Determining risk factors these can aid pre-operative and peri-operative strategies to reduced morbidity. This study aims determine the incidence predictors of intra-abdominal disease. A single-centre, retrospective was conducted. The clinical case notes patients with histopathologically proven disease, who underwent an as a one-stage or two-stage procedure, were reviewed. primary...
Abstract Aim Laparoscopic surgery is well established for colon cancer, with defined benefits. Use of laparoscopy the performance restorative proctocolectomy ( RPC ) ileoanal anastomosis more controversial. Technical aspects include difficult dissection distal rectum and a potentially increased risk anastomotic leakage through multiple firings stapler. In an attempt to overcome these difficulties we have used technique transanal rectal excision perform proctectomy. This paper describes...
Abstract Aim There is a requirement of an expansive and up to date review surgical management inflammatory bowel disease ( IBD ) that can dovetail with the medical guidelines produced by British Society Gastroenterology. Methods Surgeons who are members ACPGBI recognised interest in were invited contribute various sections guidelines. They directed produce procedure based document using literature searches systematic, comprehensible, transparent reproducible. Levels evidence graded. An...
