1Colorectal cancer:Current imaging methods and future perspectives for the diagnosis, staging and therapeutic response evaluation显示文摘In the last 10 years the mortality rate of colorectal cancer(CRC)has decreased by more than 20%due to the rising developments in diagnostic techniques and optimization of surgical,neoadjuvant and palliative therapies.Diagnostic methods currently used in the evaluation of CRC are heterogeneous and can vary within the countries and the institutions.This article aims to discuss in depth currently applied imaging modalities such as virtual computed tomography colonoscopy,endorectal ultrasound,computed tomography(CT)and magnetic resonance imaging(MRI)in the diagnosis of CRC.Special focus is put on the potential of recent diagnostic developments as diffusion weighted imaging MRI,MRI biomarkers(dynamic enhanced MRI),positron emission tomography with 2-(fluorine-18)-fluoro-2-deoxy-D-glucose(FDG-PET)combined with computed tomography(PET/CT)and new hepatobiliary MRI contrast agents.The precise role,advantage and disadvantages of these modalities are evaluated controversially in local staging,metastatic spread and treatment monitoring of CRC.Finally,the authors will touch upon the future perspectives in functional imaging evaluating the role of integrated FDG-PET/CT with perfusion CT,MRI spectroscopy of primary CRC and hepatic transit time analysis using contrast enhanced ultrasound and MRI in the detection of liver metastases.Validation of these newer imaging techniques may lead to significant improvements in the management of patients with colorectal cancer.Maka Kekelidze Luigia D'Errico Michele Pansini Anthony Tyndall Joachim Hohmann 2013World Journal of Gastroenterology2013,19,46:28
2Advances in diagnosis, treatment and palliation of pancreatic carcinoma: 1990-2010显示文摘Several advances in genetics, diagnosis and palliation of pancreatic cancer (PC) have occurred in the last decades. A multidisciplinary approach to this disease is therefore recommended. PC is relatively common as it is the fourth leading cause of cancer related mortality. Most patients present with obstructive jaundice, epigastric or back pain, weight loss and anorexia. Despite improvements in diagnostic modalities, the majority of cases are still detected in advanced stages. The only curative treatment for PC remains surgical resection. No more than 20% of patients are candidates for surgery at the time of diagnosis and survival remains quite poor as adjuvant therapies are not very effective. A small percentage of patients with borderline non-resectable PC might benefit from neo-adjuvant chemoradiation therapy enabling them to undergo resection; however, randomized controlled studies are needed to prove the benefits of this strategy. Patients with unresectable PC benefit from palliative interventions such as biliary decompression and celiac plexus block. Further clinical trials to evaluate new chemo and radiation protocols as well as identification of genetic markers for PC are needed to improve the overall survival of patients affected by PC, as the current overall 5-year survival rate of patients affected by PC is still less than 5%. The aim of this article is to review the most recent high quality literature on this topic.Chakshu Sharma Karim M Eltawil Paul D Renfrew Mark J Walsh Michele Molinari 2011World Journal of Gastroenterology2011,17,7:28
3Safety of the long-term use of proton pump inhibitors显示文摘The proton pump inhibitors (PPIs) as a class are remarkably safe and effective for persons with peptic ulcer disorders. Serious adverse events are extremely rare for PPIs, with case reports of interstitial nephritis with omeprazole, hepatitis with omeprazole and lansoprazole, and disputed visual disturbances with pantoprazole and omeprazole. PPI use is associated with the development of fundic gland polyps (FGP); stopping PPIs is associated with regression of FGP. In the absence of Helicobacter pylori infection, the long-term use of PPIs has not been convincingly proven to cause or be associated with the progression of pre-existing chronic gastritis or gastric atrophy or intestinal metaplasia. Mild/modest hypergastrinemia is a physiological response to the reduction in gastric acid secretion due to any cause. The long-term use of PPIs has not been convincingly proven to cause enterochromaff in-like cell hyperplasia or carcinoid tumors. PPIs increase the risk of community acquired pneumonia, but not of hospital acquired (nosocomial) pneumonia. There is no data to support particular care in prescribing PPI therapy due to concerns about risk of hip fracture with the long-termuse of PPIs. Long-term use of PPIs does not lead to vitamin B12 def iciencies, except possibly in the elderly, or in persons with Zollinger-Ellison Syndrome who are on high doses of PPI for prolonged periods of time. There is no convincingly proven data that PPIs increase the risk of Clostridium difficile-associated diarrhea in persons in the community. The discontinuation of PPIs may result in rebound symptoms requiring further and even continuous PPI use for suppression of symptoms. As with all medications, the key is to use PPIs only when clearly indicated, and to reassess continued use so that long-term therapy is used judiciously. Thus, in summary, the PPIs are a safe class of medications to use longterm in persons in whom there is a clear need for the maintenance of extensive acid inhibition.Alan BR Thomson Michel D Sauve Narmin Kassam Holly Kamitakahara 2010World Journal of Gastroenterology2010,16,19:20

9Cytoreduction and hyperthermic intraperitoneal chemotherapy in the treatment of peritoneal carcinomatosis from pseudomixoma peritonei显示文摘AIM:To investigate the most important aspects of hyperthermic intraperitoneal chemotherapy (HIPEC) that has been accepted as the standard treatment for pseudomyxoma peritonei (PMP),with special regard to morbidity,overall survival (OS) and disease free survival (DFS) over 10 years. METHODS:Fifty-three patients affected by PMP underwent cytoreduction (CCR) and HIPEC with a 'semi-closed' abdomen technique in our institution. The peritonectomy procedure and completeness of CCR were classifi ed according to Sugarbaker criteria. Preoperative evaluation always included thoracic and abdominal CT scan to stage peritoneal disease and exclude distant metastases. Fifty-one patients in our series were treated with a protocol based on administration of cisplatinum 100 mg/m2 plus mitomycin C 16 mg/m2,at a temperature of 41.5℃ for 60 min. Anastomoses were always performed at the end of HIPEC. The mean duration of surgery was 12 h including HIPEC. Continuous monitoring of hepatic and renal functions and hydroelectrolytic balance was performed in the postoperative period. RESULTS:Twenty-four patients presented with postoperative complications:surgical morbidity was observed in 16 patients and 6 patients were re-operated. All complications were successfully treated and no postoperative deaths were observed. Risk factors for postoperative morbidity were considered to be gender,age,body surface,duration of surgery,Peritoneal Cancer Index (PCI) and tumor residual value (CC score). No statistically signifi cant correlation was found during the multivariate analysis:only the CC score was statistically significant. The OS in our experience was 81.8%,with a DFS of 80% at 5 years and of 70% at 10 years. CONCLUSION:In our experience,even if HIPEC combined with cytoreductive surgery involves a high risk of morbidity,postoperative complications can be resolved favorably in most cases with correct patient selection and adequate postoperative care,thus minimizing mortality. The association of CCR and HIPEC can be considered as the standard treatment for PMP. The OS and DFS results confi rm the validity of this combined approach for the treatment of this rare neoplasm. The impact of preoperative chemotherapy on OS,in our opinion,is due to a major aggressiveness of tumors in treated patients.Tommaso Cioppa Marco Vaira Camilla Bing Silvia D'Amico Alessandro Bruscino Michele De Simone 2008World Journal of Gastroenterology2008,14,44:13
10Acupuncture Treatment for Idiopathic Trigeminal Neuralgia:A Longitudinal Case-Control Double Blinded Study显示文摘Objective: To evaluate the treatment effect of acupuncture on patients with idiopathic trigeminal neuralgia(ITN) by case-control longitudinal blinded study. Methods: Sixty ITN patients and 30 healthy subjects were included. The ITN patients were randomly assigned to acupuncture group(15 cases), sham-acupuncture group(15 cases) and carbamazepine group(30 cases), respectively. Clinical orofacial evaluation(including pain intensity and medication doses), research diagnostic criteria for temporomandibular disorders(RDC/TMD) and Helkimo indexes(for functional evaluation of the masticatory system), and quantitative sensory testing for sensory thresholds(gustative, olfactory, cold, warm, touch, vibration and superficial and deep pain) were evaluated before treatment, immediately after treatment, and 6 months after treatment. Results: The mean pain intensity by the Visual Analogue Scale only decreased in the acupuncture group at the last evaluation(P=0.012). Patients in the sham-acupuncture group had an increase in carbamazepine doses according to the prescriptions(P<0.01). There was a reduction in secondary myofascial pain and mandibular limitations at the acupuncture and sham-acupuncture groups, however only the acupuncture group kept the changes after 6 months(P<0.01, P=0.023). There was a decrease in mechanical thresholds in the acupuncture group(tactile, P<0.01; vibration, P=0.027) and an increase in deep pain thresholds in both acupuncture and sham-acupuncture groups(P=0.013). Conclusion: Acupuncture can be an option in the treatment of ITN due to its analgesic effect in both ITN and secondary myofascial pain associated with it.Michelle Cristina Ichida Mariana Zemuner Jorge Hosomi Hong Jin Pai Manoel Jacobsen Teixeira JoséTadeu Tesseroli de Siqueira Silvia R D T de Siqueira 2017Chinese Journal of Integrative Medicine2017,23,11:6
11Irritable bowel syndrome: A concise review of current treatment concepts显示文摘Irritable bowel syndrome(IBS) is one of the most common gastrointestinal disorders causing patients to seek medical treatment. It is relatively resource intensive and the source of significant morbidity. Recent insights into the pathophysiology and treatment of IBS has given clinicians more options than ever to contend with this disorder. The purpose of our paper is to review older, 'classic' treatments for IBS as well as newer agents and 'alternative' therapies. We discuss the evidence base of these drugs and provide context to help develop appropriate treatment plans for IBS patients.Geoffrey C Wall Ginelle A Bryant Michelle M Bottenberg Erik D Maki rew R Miesner 2014World Journal of Gastroenterology2014,20,27:5
12Management of digestive bleeding related to portal hypertension in cirrhotic patients:A French multicenter cross-sectional practice survey显示文摘AIM: To investigate the conformity of management practices of gastrointestinal hemorrhage in cirrhotic patients with relevant guidelines. METHODS: A questionnaire on the management of digestive bleeding was completed for all consecutive cirrhotic patients admitted to 31 French hospitals. RESULTS: One hundred and twenty-six bleeding events were recorded. It was the first bleeding episode in 79 patients (63%), of whom 40 (51%) had a prior diagnosis of cirrhosis and 25 (32%) had previously undergone an endoscopy. The bleeding episode was a recurrence in 46 patients (37%). The median time between onset and admission was 4 h, but exceeded 12 h in 42% of cases. There was an agreement between centers forearly vasoactive drug administration (87% of cases), association with ligation (42%) more often than sclerosis (21%) at initial endoscopy, and antibiotic prophylaxis (64%). By contrast, prescription of beta-blockade alone or in combination (0 to 100%, P = 0.003) for secondary prophylaxis and lactulose (26% to 86%, P = 0.04), differed among centers. CONCLUSION: In French hospitals, management of bleeding related to portal hypertension in cirrhotic patients is generally in keeping with the consensus. Broad variability still remains concerning beta-blockade use for secondary prophylaxis. Screening for esophageal varices, the use of antibiotic prophylaxis and patients information need to be improved.Pierre Ingrand Jérme Gournay Pierre Bernard Frédéric Oberti Brigitte Bernard-Chabert Arnault Pauwels Philippe Renard Eric Bartoli Jean-Franois Cadranel Jean-Claude Barbare Isabelle Ingrand Michel Beauchant 2006World Journal of Gastroenterology2006,12,48:4

14Endoscopy-based management decreases the risk of postoperative recurrences in Crohn's disease显示文摘AIM: To investigate whether an endoscopy-based management could prevent the long-term risk of postoperative recurrence.METHODS: From the pathology department database, we retrospectively retrieved the data of all the patients operated on for Crohn's disease(CD) in our center(1986-2015). Endoscopy-based management was defined as systematic postoperative colonoscopy(median time after surgery = 9.5 mo) in patients with no clinical postoperative recurrence at the time of endoscopy. RESULTS: From 205 patients who underwent surgery, 161 patients(follow-up > 6 mo) were included. Endoscopic postoperative recurrence occurred in 67.6%, 79.7%, and 95.5% of the patients, respectively 5, 10 and 20 years after surgery. The rate of clinical postoperative recurrence was 61.4%, 75.9%, and 92.5% at 5, 10 and 20 years, respectively. The rate of surgical postoperative recurrence was 19.0%, 38.9% and 64.7%, respectively, 5, 10 and 20 years after surgery. In multivariate analysis, previous intestinal resection, prior exposure to anti-TNF therapy before surgery, and fistulizing phenotype(B3) were postoperative risk factors. Previous perianal abscess/fistula(other perianal lesions excluded), were predictive of only symptomatic recurrence. In multivariate analysis, an endoscopy-based management(n = 49/161) prevented clinical(HR = 0.4, 95%CI: 0.25-0.66, P < 0.001) and surgical postoperative recurrence(HR = 0.30, 95%CI: 0.13-0.70, P = 0.006).CONCLUSION: Endoscopy-based management should be recommended in all CD patients within the first year after surgery as it highly decreases the long-term risk of clinical recurrence and reoperation.Anne-Laure Boucher Bruno Pereira Stéphanie Decousus Marion Goutte Felix Goutorbe Anne Dubois Johan Gagniere Corinne Borderon Juliette Joubert Denis Pezet Michel Dapoigny Pierre J Déchelotte Gilles Bommelaer Anthony Buisson 2016World Journal of Gastroenterology2016,22,21:3
15Changes in the colon microbiota and intestinal cytokine gene expression following minimal intestinal surgery显示文摘AIM: To investigate the impact of minor abdominal surgery on the caecal microbial population and on markers of gut inflammation.METHODS: Four week old piglets were randomly allocated to a no-surgery 'control' group(n = 6) or a 'transection surgery' group(n = 5).During the transection surgery procedure, a conventional midline incision of the lower abdominal wall was made and the small intestine was transected at a site 225 cm proximal to the ileocaecal valve, a 2 cm segment was removed and the intestine was re-anastomosed.Piglets received a polymeric infant formula diet throughout the study period and were sacrificed at two weeks post-surgery.Clinical outcomes including weight, stool consistency and presence of stool fat globules were monitored.High throughput DNA sequencing of colonic content was used to detect surgery-relateddisturbances in microbial composition at phylum, family and genus level.Diversity and richness estimates were calculated for the control and minor surgery groups.As disturbances in the gut microbial community are linked to inflammation we compared the gene expression of key inflammatory cytokines(TNF, IL1 B, IL18, IL12, IL8, IL6 and IL10) in ileum, terminal ileum and colon mucosal extracts obtained from control and abdominal surgery groups at two weeks post-surgery.RESULTS: Changes in the relative abundance of bacterial species at family and genus level were confined to bacterial members of the Proteobacteria and Bacteroidetes phyla.Family level compositional shifts included a reduction in the relative abundance of Enterobacteriaceae(22.95 ± 5.27 vs 2.07 ± 0.72, P < 0.01), Bacteroidaceae(2.54 ± 0.56 vs 0.86 ± 0.43, P < 0.05) and Rhodospirillaceae(0.40 ± 0.14 vs 0.00 ± 0.00, P < 0.05) following transection surgery.Similarly, at the genus level, changes associated with transection surgery were restricted to members of the Proteobacteria and Bacteroidetes phyla and included decreased relative abundance of Enterobacteriaceae(29.20 ± 6.74 vs 2.88 ± 1.08, P < 0.01), Alistipes(4.82 ± 1.73 vs 0.18 ± 0.13, P < 0.05) and Thalassospira(0.53 ± 0.19 vs 0.00 ± 0.00, P < 0.05).Surgeryassociated microbial dysbiosis was accompanied by increased gene expression of markers of inflammation.Within the ileum IL6 expression was decreased(4.46 ± 1.60 vs 0.24 ± 0.06, P < 0.05) following transection surgery.In the terminal ileum, gene expression of TNF was decreased(1.51 ± 0.13 vs 0.80 ± 0.16, P < 0.01) and IL18(1.21 ± 0.18 vs 2.13 ± 0.24, P < 0.01), IL12(1.04 ± 0.16 vs 1.82 ± 0.32, P < 0.05) and IL10(1.04 ± 0.06 vs 1.43 ± 0.09, P < 0.01) gene expression increased following transection surgery.Within the colon, IL12(0.72 ± 0.13 vs 1.78 ± 0.28, P < 0.01) and IL10(0.98 ± 0.02 vs 1.95 ± 0.14, P < 0.01) gene expression were increased following transection surgery.CONCLUSION: This study suggests that minor abdominal surgery in infants, results in long-term alteration of the colonic microbial composition and persistent gastrointestinal inflammation.Susan Lapthorne Julie E Bines Fiona Fouhy Nicole L Dellios Guineva Wilson Sarah L Thomas Michelle Scurr Catherine Stanton Paul D Cotter Prue M Pereira-Fantini 2015World Journal of Gastroenterology2015,21,14:3
16Intraoperative use of indocyanine green fluorescence imaging in rectal cancer surgery: The state of the art显示文摘Indocyanine green(ICG)fluorescence imaging is widely used in abdominal surgery.The implementation of minimally invasive rectal surgery using new methods like robotics or a transanal approach required improvement of optical systems.In that setting,ICG fluorescence optimizes intraoperative vision of anatomical structures by improving blood and lymphatic flow.The purpose of this review was to summarize all potential applications of this upcoming technology in rectal cancer surgery.Each type of use has been separately addressed and the evidence was investigated.During rectal resection,ICG fluorescence angiography is mainly used to evaluate the perfusion of the colonic stump in order to reduce the risk of anastomotic leaks.In addition,ICG fluorescence imaging allows easy visualization of organs such as the ureter or urethra to protect them from injury.This intraoperative technology is a valuable tool for conducting lymph node dissection along the iliac lymphatic chain or to better identifying the rectal dissection planes when a transanal approach is performed.This is an overview of the applications of ICG fluorescence imaging in current surgical practice and a synthesis of the results obtained from the literature.Although further studies are need to investigate the real clinical benefits,these findings may enhance use of ICG fluorescence in current clinical practice and stimulate future research on new applications.Roberto Peltrini Mauro Podda Simone Castiglioni Maria Michela Di Nuzzo Michele D'Ambra Ruggero Lionetti Maurizio Sodo Gaetano Luglio Felice Mucilli Salomone Di Saverio Umberto Bracale Francesco Corcione 2021World Journal of Gastroenterology2021,27,38:3

18Macrophage secretory products induce an inflammatory phenotype in hepatocytes显示文摘AIM:To investigate the influence of macrophages on hepatocyte phenotype and function.METHODS:Macrophages were differentiated from THP-1 monocytes via phorbol myristate acetate stimulation and the effects of monocyte or macrophageconditioned medium on HepG2 mRNA and protein expression determined.The in vivo relevance of these findings was confirmed using liver biopsies from 147 patients with hepatitis C virus(HCV)infection.RESULTS:Conditioned media from macrophages,but not monocytes,induced a transient morphological change in hepatocytes associated with upregulation of vimentin(7.8±2.5-fold,P=0.045)and transforming growth factor(TGF)-β1(2.6±0.2-fold,P<0.001)and downregulation of epithelial cadherin(1.7±0.02-fold,P=0.017)mRNA expression.Microarray analysis revealed significant upregulation of lipocalin-2(17-fold,P <0.001)and pathways associated with inflammation,and substantial downregulation of pathways related to hepatocyte function.In patients with chronic HCV,realtime polymerase chain reaction and immunohistochemistry confirmed an increase in lipocalin-2 mRNA(F0 1.0 ±0.3,F1 2.2±0.2,F2 3.0±9.3,F3/4 4.0±0.8,P= 0.003)and protein expression(F1 1.0±0.5,F2 1.3± 0.4,F3/4 3.6±0.4,P=0.014)with increasing liver injury.High performance liquid chromatography-tandem mass spectrometry analysis identified elevated levels of matrix metalloproteinase(MMP)-9 in macrophageconditioned medium,and a chemical inhibitor of MMP-9 attenuated the change in morphology and mRNA expression of TGF-β1(2.9±0.2 vs 1.04±0.1,P<0.001) in macrophage-conditioned media treated HepG2 cells.In patients with chronic HCV infection,hepatic mRNA expression of CD163(F0 1.0±0.2,F1/2 2.8±0.3,F3/4 5.3±1.0,P=0.001)and MMP-9(F0 1.0±0.4,F1/2 2.8±0.3,F3/4 4.1±0.8,P=0.011)was significantly associated with increasing stage of fibrosis.CONCLUSION:Secreted macrophage products alter the phenotype and function of hepatocytes,with increased expression of inflammatory mediators,suggesting that hepatocytes actively participate in liver injury.Michelle Melino Victoria L Gadd Gene V Walker Richard Skoien Helen D Barrie Dinesh Jothimani Leigh Horsfall Alun Jones Matthew J Sweet Gethin P Thomas Andrew D Clouston Julie R Jonsson Elizabeth E Powell 2012World Journal of Gastroenterology2012,18,15:3

20Psychosocial mechanisms for the transmission of somatic symptoms from parents to children显示文摘AIM: To examine familial aggregation of irritable bowel syndrome(IBS) via parental reinforcement/modeling of symptoms, coping, psychological distress, and exposure to stress.METHODS:Mothers of children between the ages of8 and 15 years with and without IBS were identified through the Group Health Cooperative of Puget Sound.Mothers completed questionnaires,including the Child Behavior Checklist(child psychological distress),the Family Inventory of Life Events(family exposure to stress),SCL-90R(mother psychological distress),and the Pain Response Inventory(beliefs about pain).Children were interviewed separately from their parents and completed the Pain Beliefs Questionnaire(beliefs about pain),Pain Response Inventory(coping)and Child Symptom Checklist[gastrointestinal(GI)symptoms].In addition,health care utilization data was obtained from the automated database of Group Health Cooperative.Mothers with IBS(n=207)and their 296 children were compared to 240 control mothers and their 335 children,while controlling for age and education.RESULTS:Hypothesis 1:reinforcement of expression of GI problems is only related to GI symptoms,but not others(cold symptoms)in children.There was no significant correlation between parental reinforcement of symptoms and child expression of GI or other symptoms.Hypothesis 2:modeling of GI symptomsis related to GI but not non-GI symptom reporting in children.Children of parents with IBS reported more non-GI(8.97 vs 6.70,P<0.01)as well as more GI(3.24 vs 2.27,P<0.01)symptoms.Total health care visits made by the mother correlated with visits made by the child(rho=0.35,P<0.001 for cases,rho=0.26,P<0.001 for controls).Hypothesis 3:children learn to share the methods of coping with illness that their mothers exhibit.Methods used by children to cope with stomachaches differed from methods used by their mothers.Only 2/16 scales showed weak but significant correlations(stoicism rho=0.13,P<0.05;acceptance rho=0.13,P<0.05).Hypothesis 4:mothers and children share psychological traits such as anxiety,depression,and somatization.Child psychological distress correlated with mother’s psychological distress(rho=0.41,P<0.001 for cases,rho=0.38,P<0.001 for controls).Hypothesis 5:stress that affects the whole family might explain the similarities between mothers and their children.Family exposure to stress was not a significant predictor of children’s symptom reports.Hypothesis 6:the intergenerational transmission of GI illness behavior may be due to multiple mechanisms.Regression analysis identified multiple independent predictors of the child’s GI complaints,which were similar to the predictors of the child’s non-GI symptoms(mother’s IBS status,child psychological symptoms,child catastrophizing,and child age).CONCLUSION:Multiple factors influence the reporting of children’s gastrointestinal and non-gastrointestinal symptoms.The clustering of illness within families is best understood using a model that incorporates all these factors.Miranda AL van Tilburg Rona L Levy Lynn S Walker Michael Von Korff Lauren D Feld Michelle Garner Andrew D Feld William E Whitehead 2015World Journal of Gastroenterology2015,21,18:2
