Colonoscopy and endoscopic removal of precancerous polyps play an important role in colorectal cancer (CRC) prevention. Improved endoscopes and quality standards have led to an increasing polyp and adenoma detection rate. Optimal polyp resection techniques and management strategies are key for an effective colonoscopy practice. Areas covered: Strategies for how to improve diminutive polyp (polyps up to 5mm in size) management are discussed because of their high prevalence. Systematic removal of diminutive polyps leads to increasing costs of colonoscopy practice, while the effect on colorectal cancer prevention might be negligible...

OBJECTIVE: Create practice guidelines for the appropriate use of red blood cell transfusions in hepatectomy. BACKGROUND: Hepatectomy is associated with a high prevalence of transfusions. A transfusion can be life-saving, but can be associated with important adverse effects. Given the prevalence, the potential for benefit and harm, and the difficulty in conducting clinical trials, transfusion in hepatectomy is well-suited for a study of appropriateness. METHODS: Using the RAND/UCLA appropriateness method, an international, multidisciplinary expert panel in hepatobiliary surgery, anesthesia, transfusion medicine, and critical care rated a series of 468 perioperative scenarios for transfusion appropriateness...

BACKGROUND: The introduction of minimally invasive pancreatic resection (MIPR) into surgical practice has been slow. The worldwide utilization of MIPR and attitude towards future perspectives of MIPR remains unknown. METHODS: An anonymous survey on MIPR was sent to the members of six international associations of Hepato-Pancreato-Biliary (HPB) surgery. RESULTS: The survey was completed by 435 surgeons from 50 countries, with each surgeon performing a median of 22 (IQR 12-40) pancreatic resections annually...

Background. The safety of endoscopy after an acute coronary syndrome (ACS) is poorly characterized. We thus performed a systematic review assessing the safety of endoscopy following ACS. Methods. Searches in EMBASE, Medline, and Web of Science identified articles for inclusion. Data abstraction was completed by two independent reviewers. Results. Fourteen retrospective studies yielded 1178 patients (mean 71.3 years, 59.0% male) having suffered an ACS before endoscopy. Patients underwent 1188 endoscopies primarily to investigate suspected gastrointestinal bleeding (81...

We examine the impact of key variables on the likelihood of inpatient poor bowel preparation for colonoscopy. Records of inpatients that underwent colonoscopy at our institution between January 2010 and December 2011 were retrospectively extracted. Univariable and multivariable logistic regression models were fitted to assess the effect of clinical variables on the odds of poor preparation. Tested predictors included age; gender; use of narcotics; heavy medication burden; comorbidities; history of previous abdominal surgery; neurological disorder; product used for bowel preparation, whether or not the bowel regimen was given as split or standard dose; and time of endoscopy...

BACKGROUND: Difficult cannulation is a risk factor for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP). It has been postulated that the pancreatic duct guidewire (PGW) technique may improve biliary cannulation success and reduce the risk of PEP in people with difficult cannulation. OBJECTIVES: To systematically review evidence from randomised controlled trials (RCTs) assessing the effectiveness and safety of the PGW technique compared to persistent conventional cannulation (CC) (contrast- or guidewire-assisted cannulation) or other advanced techniques in people with difficult biliary cannulation for the prevention of PEP...

Yen-I Chen, Alan N Barkun
Topical hemostatic agents and powders are an emerging modality in the endoscopic management of upper and lower gastrointestinal bleeding. This systematic review demonstrates the effectiveness and safety of these agents with special emphasis on TC-325 and Ankaferd Blood Stopper. The unique noncontact/nontraumatic application, ability to cover large areas of bleed, and ease of use make these hemostatic agents an attractive option in certain clinical situations, such as massive bleeding with poor visualization, salvage therapy, and diffuse bleeding from luminal malignancies...

BACKGROUND: Enrolling patients in studies of pancreatic ductal adenocarcinoma (pdac) is challenging because of the high fatality of the disease. We hypothesized that a prospective clinic-based study with rapid ascertainment would result in high participation rates. Using that strategy, we established the Quebec Pancreas Cancer Study (qpcs) to investigate the genetics and causes of pdac and other periampullary tumours (pats) that are also rare and underrepresented in research studies. METHODS: Patients diagnosed with pdac or pat were introduced to the study at their initial clinical encounter, with a strategy to enrol participants within 2 weeks of diagnosis...

REVIEW

Bleeding from stress-related mucosal disease in critically ill patients remains an important clinical management issue. Although only a small proportion (1-6%) of patients admitted to an intensive care unit (ICU) will bleed, a substantial proportion exhibit clinical risk factors (mechanical ventilation for >48 h and a coagulopathy) that predict an increased risk of bleeding. Furthermore, upper gastrointestinal mucosal lesions can be found in 75-100% of patients in ICUs. Although uncommon, stress-ulcer bleeding is a severe complication with an estimated mortality of 40-50%, mostly from decompensating an underlying condition or multiorgan failure...

BACKGROUND: The operative dictation (OD) is the cornerstone of surgical communication, yet there appears to be a lack of formal education of this skill by training programs. We conducted a review of the literature to assess the teaching and quality of OD in surgical residency programs. STUDY DESIGN: Multiple databases were searched for studies pertaining to "OD," "surgical education," and "formal teaching." Of 50 the studies, 13 were retained and assigned to one or more of the following categories: (1) surveys of the surgical community evaluating current perceptions of formal OD education (n = 5), (2) studies assessing the quality of OD performed by residents (n = 5), and (3) educational interventions for improving OD skills (n = 4)...
