RESUMO
Our knowledge of the pathophysiology of eosinophilic esophagitis is constantly evolving. There is significant association between eosinophilic esophagitis and atopy; however, multiple studies have refuted the role of IgE in its pathogenesis. Instead, new data have demonstrated an elevated IgG4 level in patients with eosinophilic esophagitis. We review the current understanding of eosinophilic esophagitis pathogenesis and highlight the increasing evidence for the role of IgG4.

BACKGROUND: Multidisciplinary team meetings (MDTM) have proven efficacy in cancer management. Whilst widely implemented in inflammatory bowel disease (IBD) care, their value is yet to be investigated. We reviewed the performance of MDTM for IBD patients. METHODS: Retrospective review of MDTM from March 2013 to July 2016. Each patient's first MDTM was considered. Data collected included: report production and location, disease factors, recommendation(s), implementation and barriers to implementation. The MDTM process was considered successful when at least top-level recommendations were implemented within 6 months. RESULTS: MDTM attendance included an IBD gastroenterologist, surgeons, a radiologist, nurses, dieticians, psychologists and clinical trial staff. Initial MDTM encounters of 166 patients were reviewed: 86 females, mean age 40 years, 140 (84.3%) with Crohn disease and mean disease duration of 10.8 years (interquartile range 15 years). Electronic reports were filed for all patients, with hard copies in 84%. In 151 of 166 episodes, all (n = 127) or top-line (n = 24) recommendations were implemented, although there was a delay beyond 6 months in 5. Of 146 patients with a successful MDTM, 85 (58.2%) were in clinical remission at last review (median follow up: 27 months). Amongst patients with unsuccessful MDTM (n = 13), only two (15.4%) were in clinical remission at follow up. Barriers to implementation included patients declining recommendations and loss to follow up. CONCLUSION: The majority of MDTM encounters were successful from both a process and clinical outcome perspective. System opportunities to improve the process include ensuring that 100% of reports are available and addressing implementation delays. Patient factors that require addressing include improved engagement and understanding reasons for declining recommendations.

The role of endoscopic procedures, in both diagnostic and therapeutic purposes is continually expanding and evolving rapidly. In this context, endoscopists will encounter patients prescribed on anticoagulant and antiplatelet medications frequently. This poses an increased risk of intraprocedural and delayed gastrointestinal bleeding. Thus, there is now greater importance on optimal pre, peri and post-operative management of anticoagulant and/or antiplatelet therapy to minimise the risk of post-procedural bleeding, without increasing the risk of a thromboembolic event as a consequence of therapy interruption. Currently, there are position statements and guidelines from the major gastroenterology societies. These are available to assist endoscopists with an evidenced-based systematic approach to anticoagulant and/or antiplatelet management in endoscopic procedures, to ensure optimal patient safety. However, since the publication of these guidelines, there is emerging evidence not previously considered in the recommendations that may warrant changes to our current clinical practices. Most notably and divergent from current position statements, is a growing concern regarding the use of heparin bridging therapy during warfarin cessation and its associated risk of increased bleeding, suggestive that this practice should be avoided. In addition, there is emerging evidence that anticoagulant and/or antiplatelet therapy may be safe to be continued in cold snare polypectomy for small polyps (< 10 mm).
RESUMO
STUDY AIM: To assess the clinical outcomes of patients who received direct percutaneous endoscopic jejunostomy (DPEJ) for enteral feeding. MATERIALS AND METHODS: This is a 10-year cohort study in a single tertiary center. Main outcome measurements were technical success, and short- and long-term outcomes. DPEJ was attempted in 83 patients (51 men; 55â±â2 years) for dysphagia (nâ=â35), gastroparesis with recurrent aspiration (nâ=â30), and levodopa drug infusion for severe Parkinson's disease (nâ=â18). RESULTS: DPEJ was successful in 75 (90â%) patients. All technical failures were related to the inability to find adequate trans-illumination, and were not influenced by BMI, age, gender, or indication. Peri-operative (30-day) adverse events occurred in 11 (13â%) patients, including wound infection (3), leakage around the stoma (4), minor bleeding requiring no intervention (2), and aspiration (1). There was one case (1.2â%) of gastric perforation after PEJ insertion for levodopa drug infusion trial. This 60-year-old woman required an emergency laparotomy with nil complications, and levodopa drug infusion recommenced successfully. One case of intestinal perforation (1.2â%) occurred after jejunostomy tube replacement at 6 months of insertion, which was successfully managed with surgery. There were no peri-operative deaths. Adequate delivery of enteral feeding or Duodopa drug was achieved in 66/73 (90â%) patients, with evidence of weight gain or improvement in Parkinson's disease. Seven (8â%) continued to have clinical regurgitation but not aspiration. After a median follow-up of 84 months, 27 (33â%) patients died of their underlying diseases. Seven (8â%) had marked improvement in their underlying disease and had PEJ removed after 5 months (range 1â-â8 months). LIMITATIONS: Single center study. CONCLUSIONS: DPEJ is associated with a high technical success rate (90â%), a relatively low rate of peri-operative adverse events (13â%) and an improvement in long-term nutritional support in the majority of patients (90â%). DPEJ should be the procedure of choice to gain enteral access for feeding or drug delivery prior to considering surgery.
