1Comparison between double-balloon and single-balloon enteroscopy in therapeutic ERC after Roux-en-Y entero-enteric anastomosis显示文摘AIM:To compare the efficacy of double-balloon enteroscopy (DBE) and single-balloon enteroscopy (SBE) in therapeutic endoscopic retrograde cholangiography (ERC) in patients with Roux-en-Y entero-enteric anastomosis.METHODS:Retrospective analysis of our patient cohort revealed 4 patients with enterobiliary anastomosis and Roux-en-Y entero-enteric anastomosis who underwent repeated ERC with DBE and SBE because of recurrent cholangitis.RESULTS:A total of 38 endoscopic retrograde cholangiopancreatography procedures were performed in 25 patients with Roux-en-Y entero-enteric anastomosis.DBE was used in 29 procedures and SBE in 9.The 4 patients who underwent repeated ERC with DBE and SBE suffered from recurrent cholangitis due to stenosis of the enterobiliary anastomosis.ERC was performed repeatedly to achieve balloon dilation with/without biliary stone extraction and multiple stent placement at the level of the enterobiliary anastomosis.In all 4 patients DBE and SBE were equally successful.Compared to DBE,SBE was equally effective in passing the Roux-en-Y entero-enteric anastomosis,reaching the enterobiliary anastomosis and performing therapeutic ERC.CONCLUSION:This retrospective comparison shows that DBE and SBE are equally successful in the performance of therapeutic ERC at the level of the enterobiliary anastomosis after Roux-en-Y entero-enteric anastomosis.Tom G Moreels Paul A Pelckmans 2010World Journal of Gastrointestinal Endoscopy2010,2,9:14

3Schistosoma mansoni proteins attenuate gastrointestinal motility disturbances during experimental colitis in mice显示文摘AIM:To investigate the therapeutic effect of Schistosoma mansoni(S.mansoni) soluble worm proteins on gastrointestinal motility disturbances during experimental colitis in mice. METHODS:Colitis was induced by intrarectal injection of trinitrobenzene sulphate(TNBS) and 6 h later,mice were treated ip with S.mansoni proteins.Experiments were performed 5 d after TNBS injection.Inflammationwas quantified using validated inflammation parameters. Gastric emptying and geometric center were measured to assess in vivo gastrointestinal motility.Peristaltic activity of distal colonic segments was studied in vitro using a modified Trendelenburg set-up.Cytokine profiles of T-lymphocytes isolated from the colon were determined by real time reverse transcriptase-polymerase chain reaction. RESULTS:Intracolonic injection of TNBS caused severe colitis.Treatment with S.mansoni proteins significantly ameliorated colonic inflammation after 5 d.TNBS did not affect gastric emptying but significantly decreased the geometric center and impaired colonic peristaltic activity 5 d after the induction of colitis.Treatment with S.mansoni proteins ameliorated these in vivo and in vitro motility disturbances.In addition,TNBS injection caused a downregulation of effector T cell cytokines after 5 d,whereas a S.mansoni protein effect was no longer observed at this time point. CONCLUSION:Treatment with S.mansoni proteins attenuated intestinal inflammation and ameliorated motility disturbances during murine experimental colitis.Nathalie E Ruyssers Benedicte Y De Winter Joris G De Man Natacha D Ruyssers Ann J Van Gils Alex Loukas Mark S Pearson Joel V Weinstock Paul A Pelckmans Tom G Moreels 2010World Journal of Gastroenterology2010,16,6:11
4Acute necrotizing pancreatitis as fi rst manifestation of primary hyperparathyroidism显示文摘We report the case of a female patient with severe acute necrotizing pancreatitis associated with hypercalcemia as first manifestation of primary hyperparathyroidism caused by a benign parathyroid adenoma.Initially the acute pancreatitis was treated conservatively.The patient subsequently underwent surgical resection of the parathyroid adenoma and surgical clearance of a large infected pancreatic pseudocyst.Although the association of parathyroid adenoma-induced hypercalcemia and acute pancreatitis is a known medical entity,it is very uncommon.The pathophysiology of hypercalcemia-induced acute pancreatitis is therefore not well known,although some mechanisms have been proposed.It is important to treat the provoking factor.Therefore,the cause of hypercalcemia should be identif ied early.Surgical resection of the parathyroid adenoma is the ultimate therapy.Jeroen I Lenz Jimmy M Jacobs Bart Op de Beeck Ivan A Huyghe Paul A Pelckmans Tom G Moreels 2010World Journal of Gastroenterology2010,16,23:9

6Antioxidant enriched enteral nutrition and oxidative stress after major gastrointestinal tract surgery显示文摘AIM: To investigate the effects of an enteral supple-ment containing antioxidants on circulating levels of antioxidants and indicators of oxidative stress after major gastrointestinal surgery.METHODS: Twenty-one patients undergoing major upper gastrointestinal tract surgery were randomised in a single centre, open label study on the effect of postoperative enteral nutrition supplementedwith antioxidants. The effect on circulating levels of antioxidants and indicators of oxidative stress, such as F2-isoprostane, was studied. RESULTS: The antioxidant enteral supplement showed no adverse effects and was well tolerated. After surgery a decrease in the circulating levels of antioxidant parameters was observed. Only selenium and glutamine levels were restored to pre-operative values one week after surgery. F2-isoprostane increased in the first three postoperative days only in the antioxidant supplemented group. Lipopolysaccharide binding protein (LBP) levels decreased faster in the antioxidant group after surgery.CONCLUSION: Despite lower antioxidant levels there was no increase in the circulating markers of oxidative stress on the first day after major abdominal surgery. The rise in F2-isoprostane in patients receiving the antioxidant supplement may be related to the conversion of antioxidants to oxidants which raises questions on antioxidant supplementation. Module AOX restored the postoperative decrease in selenium levels. The rapid decrease in LBP levels in the antioxidant group suggests a possible protective effect on gut wall integrity. Further studies are needed on the role of oxidative stress on outcome and the use of antioxidants in patients undergoing major abdominal surgery.Mireille FM van Stijn Gerdien C Ligthart-Melis Petra G Boelens Peter G Scheffer Tom Teerlink Jos WR Twisk Alexander PJ Houdijk Paul AM van Leeuwen 2008World Journal of Gastroenterology2008,14,45:4
7Endoscopic retrograde cholangiopancreatography in patients with altered anatomy: How to deal with the challenges?显示文摘Endoscopic retrograde cholangiopancreatography(ERCP) in patients with surgically altered anatomy is challenging. Several operative interventions of both the gastrointestinal tract and the biliary and/or pancreatic system lead to altered anatomy, rendering ERCP more difficult or even impossible with a conventional side-viewing duodenoscope. Adapted endoscopes are avail-able to reach the biliopancreatic system and to perform ERCP in patients with altered anatomy. However, both technical difficulties and complications determine the procedure's success. Different technical approaches have been described and are highly dependent on local expertise and endoscopic equipment. Standard-ized practical guidelines are currently unavailable. This review focuses on the challenges encountered during ERCP in patients with altered anatomy and how to deal with them. The first challenge is reaching the papilla or the bilioenteric/pancreatoenteric anastomosis in the patient with postoperative altered anatomy. The sec-ond challenge is the cannulation of the biliopancreatic system and performing all conventional ERCP interven-tions and the third challenge is the control of possible complications. The available literature data on this topicis reviewed and illustrated with clinical cases.Tom G Moreels 2014World Journal of Gastrointestinal Endoscopy2014,6,8:3
8How to treat intestinal obstruction due to malignant recurrence after Whipple's resection for pancreatic head cancer: description of 2 new endoscopic techniques显示文摘The prognosis of pancreatic cancer remains poor,even after initial surgical therapy. Local recurrence after Whipple's pancreatico-duodenectomy may lead to intestinal obstruction at the level of the afferent limb or the alimentary limb. Endoscopic insertion of a selfexpandable metal stent(SEMS) into the intestinal malignant stricture is the preferred method of choice for palliation. We describe two new endoscopic techniques to treat a malignant intestinal obstruction with the insertion of a SEMS into the afferent limb and the alimentary limb. A case of malignant gastric outlet obstruction after a Whipple's resection was treated by the creation of an endoscopic gastrojejunostomy by the insertion of a lumen apposing Hot Axios stent in between the stomach and the alimentary limb under fluoroscopic and endoscopic ultrasound control. Biliary obstruction and jaundice caused by a malignant stricture of the afferent limb after a Roux-en-Y Whipple's resection was treated by the insertion of a SEMS by means of the single-balloon overtube-assisted technique under fluoroscopic control. Feasibility and advantages of both techniques are discussed.Christina Mouradides Alaa Taha Ivan Borbath Pierre H Deprez Tom G Moreels 2017World Journal of Gastroenterology2017,23,33:3

10Age at diagnosis of type 2 diabetes and cardiovascular risk factor profile:A pooled analysis显示文摘BACKGROUND The diagnosis of type 2 diabetes(T2D)in younger adults,an increasingly common public health issue,is associated with a higher risk of cardiovascular complications and mortality,which may be due to a more adverse cardiovascular risk profile in individuals diagnosed at a younger age.AIM To investigate the association between age at diagnosis and the cardiovascular risk profile in adults with T2D.METHODS A pooled dataset was used,comprised of data from five previous studies of adults with T2D,including 1409 participants of whom 196 were diagnosed with T2D under the age of 40 years.Anthropometric and blood biomarker measurements included body weight,body mass index(BMI),waist circumference,body fat percentage,glycaemic control(HbA1c),lipid profile and blood pressure.Univariable and multivariable linear regression models,adjusted for diabetes duration,sex,ethnicity and smoking status,were used to investigate the association between age at diagnosis and each cardiovascular risk factor.RESULTS A higher proportion of participants diagnosed with T2D under the age of 40 were female,current smokers and treated with glucose-lowering medications,compared to participants diagnosed later in life.Participants diagnosed with T2D under the age of 40 also had higher body weight,BMI,waist circumference and body fat percentage,in addition to a more adverse lipid profile,compared to participants diagnosed at an older age.Modelling results showed that each one year reduction in age at diagnosis was significantly associated with 0.67 kg higher body weight[95%confidence interval(CI):0.52-0.82 kg],0.18 kg/m^(2) higher BMI(95%CI:0.10-0.25)and 0.32 cm higher waist circumference(95%CI:0.14-0.49),after adjustment for duration of diabetes and other confounders.Younger age at diagnosis was also significantly associated with higher HbA1c,total cholesterol,low-density lipoprotein cholesterol and triglycerides.CONCLUSION The diagnosis of T2D earlier in life is associated with a worse cardiovascular risk factor profile,compared to those diagnosed later in life.Mary M Barker Francesco Zaccardi Emer M Brady Gaurav S Gulsin Andrew P Hall Joseph Henson Zin ZinHtike Kamlesh Khunti Gerald P McCann Emma L Redman David R Webb Emma G Wilmot Tom Yates Jian Yeo Melanie J Davies Jack A Sargeant 2022World Journal of Diabetes2022,13,3:2

12N-acetyl-L-cysteine combined with mesalamine in the treatment of ulcerative colitis: Randomized,placebo-controlled pilot study显示文摘AIM: To evaluate the effectiveness and safety of oral N-acetyl-L-cysteine (NAC) co-administration with mesalamine in ulcerative colitis (UC) patients. METHODS: Thirty seven patients with mild to moderate UC were randomized to receive a four-wk course of oral mesalamine (2.4 g/d) plus N-acetyl-L-cysteine (0.8 g/d) (group A) or mesalamine plus placebo (group B). Patients were monitored using the Modified Truelove-Witts Severity Index (MTWSI). The primary endpoint was clinical remission (MTWSI ≤ 2) at 4 wk. Secondary endpoints were clinical response (defined as a reduction from baseline in the MTWSI of ≥ 2 points) and drug safety. The serum TNF-α, interleukin-6, interleukin-8 and MCP-1 were evaluated at baseline and at 4 wk of treatment. RESULTS: Analysis per-protocol criteria showed clinical remission rates of 63% and 50% after 4 wk treatment with mesalamine plus N-acetyl-L-cysteine (group A) and mesalamine plus placebo (group B) respectively (OR = 1.71; 95% CI: 0.46 to 6.36; P = 0.19; NNT = 7.7). Analysis of variance (ANOVA) of data indicated a significant reduction of MTWSI in group A (P = 0.046) with respect to basal condition without significant changes in the group B (P = 0.735) during treatment. Clinical responses were 66% (group A) vs 44% (group B) after 4 wk of treatment (OR = 2.5; 95% CI: 0.64 to 9.65; P = 0.11; NNT = 4.5). Clinical improvement in group A correlated with a decrease of IL-8 and MCP-1. Rates of adverse events did not differ significantly between both groups. CONCLUSION: In group A (oral NAC combined with mesalamine) contrarily to group B (mesalamine alone), the clinical improvement correlates with a decrease of chemokines such as MCP-1 and IL-8. NAC addition not produced any side effects.Luis G Guijarro Jose Mate Javier P Gisbert Jose Luis Perez-Calle Ignacio Marín-Jimenez Encarna Arriaza Tomás Olleros Mario Delgado Maria S Castillejo David Prieto-Merino Venancio Gonzalez Lara Amado Salvador Pea 2008World Journal of Gastroenterology2008,14,18:2
