| 1 | Proposal of an ultrasonographic classification for hepatic alveolar echinococcosis: Echinococcosis multilocularis Ulm classification-ultrasound显示文摘AIM: To establish an ultrasonographic classification based on a large sample of patients with confirmed hepatic alveolar echinococcosis(AE).METHODS: Clinical data and ultrasonography(US) findings of 185 patients(100 males; 85 females; mean age at diagnosis: 51.4 ± 17.6 years; mean age at time of US examination: 58.7 ± 18.2 years) were retrospectively reviewed with respect to the US morphology of hepatic AE lesions. The sonomorphological findings were grouped according to a five-part classification scheme.RESULTS: Application of the new classification resulted in the following distribution of sonomorphological patterns among the patients examined: hailstorm(54.1%); pseudocystic(13.5%); ossification(13.0%); hemangioma-like(8.1%); and metastasis-like(6.5%). Only 4.9% of lesions could not be assigned to a sonomorphological pattern.CONCLUSION: The sonomorphological classification proposed in the present study facilitates the diagnosis,interpretation and comparison of hepatic alveolar echinococcosis in routine practice and in the context of scientific studies. | Wolfgang Kratzer Beate Gruener Tanja EM Kaltenbach Sarina Ansari-Bitzenberger Peter Kern Michael Fuchs Richard A Mason Thomas FE Barth Mark M Haenle Andreas Hillenbrand Suemeyra Oeztuerk Tilmann Graeter | 2015 | World Journal of Gastroenterology2015，21，43： | 16 |
| 2 | Parameters affecting different acoustic radiation force impulse applications in the diagnosis of fibrotic liver changes显示文摘AIM: To analyze the virtual touch tissue quantification(VTTQ) and virtual touch imaging quantification(VTIQ) techniques, and identify possible factors that may influence VTTQ and VTIQ measurements.METHODS: One hundred and eighty-six(104 women/82 men) of 323 subjects met the inclusion criteria(age > 18 years, no history of chronic or gastrointestinal disease, body-mass index(BMI) < 30 kg/m2, a fasting period of at least three hours, no history of hepatotoxic pharmaceuticals, alcohol consumption < 24 g/d in men and < 12 g/d in women, and normal findings upon ultrasound examination of the abdomen). Measurements were taken at depths of 50 mm with VTTQ, 15 mm and 25 mm with VTIQ in the right hepatic lobe, and at 15 mm with only VTIQ in the left hepatic lobe. The examiner acquired six measurements per position, thereby giving 24 measurements in total.RESULTS: The 95% confidence intervals of mean were1.23-1.29 m/s for VTTQ and 1.29-1.37 m/s, 1.17-1.23 m/s, and 1.48-1.57 m/s for VTIQ in a depth of 15 mm and 25 mm in the right hepatic lobe and 15 mm in the left hepatic lobe. Only superficial measurements in the right hepatic lobe with the VTIQ method exhibited an effect of age on shear wave velocity. Measurements acquired using the 6C1 probe with the VTTQ method showed no dependence on BMI. By comparison, BMI influenced measurements taken with the VTIQ method using the 9L4 probe in the superficial and deep areas of the right hepatic lobe, as well as in the left hepatic lobe(P = 0.0160, P = 0.0019, P = 0.0173, respectively). Gender influenced measurements at depths of 50 mm with VTTQ and 25 mm with VTIQ in the right hepatic lobe(P = 0.0001, P = 0.0269). Significant differences were found between measurements with the 6C1(VTTQ) and 9L4 probes(VTIQ)(P = 0.0067), between superficial and deep measurements(P < 0.0001), and between the right and left lobes of the liver(P < 0.0001). CONCLUSION: Measurements in the right lobe and deep regions are preferable. Gender differences must be considered. BMI must be considered when assessing VTIQ technology. | Sabrina Galgenmueller Heike Jaeger Wolfgang Kratzer Stefan A Schmidt Suemeyra Oeztuerk Mark M Haenle Richard A Mason Tilmann Graeter | 2015 | World Journal of Gastroenterology2015，21，27： | 5 |

| 4 | Clinical classification of symptomatic heterotopic pancreas of the stomach and duodenum:A case series and systematic literature review显示文摘BACKGROUND Heterotopic pancreas(HP)is an aberrant anatomic malformation that occurs most commonly in the upper gastrointestinal tract.While the majority of heterotopic pancreatic lesions are asymptomatic,many manifest severe clinical symptoms which require surgical or endoscopic intervention.Understanding of the clinical manifestations and symptoms of HP is limited due to the lack of large volume studies in the literature.The purpose of this study is to review symptomatic cases at a single center and compare these to a systematic review of the literature in order to characterize common clinical manifestations and treatment of this disease.AIM To classify the common clinical manifestations of heterotopic pancreas.METHODS A retrospective review was conducted of pathologic samples containing heterotopic pancreas from 2000-2018.Review was limited to HP of the upper gastrointestinal tract due to the frequency of presentation in this location.Symptomatic patients were identified from review of the medical records and clinical symptoms were tabulated.These were compared to a systematic review of the literature utilizing Pub Med and Embase searches for papers pertaining to heterotopic pancreas.Publications describing symptomatic presentation of HP were selected for review.Information including demographics,symptoms,presentation and treatment were compiled and analyzed.RESULTS Twenty-nine patient were identified with HP at a single center,with six of these identified has having clinical symptoms.Clinical manifestations included,gastrointestinal bleeding,gastric ulceration with/without perforation,pancreatitis,and gastric outlet obstruction.Systemic review of the literature yielded 232 publications detailing symptomatic cases with only 20 studies describing ten or more patients.Single and multi-patient studies were combined to form a cohort of 934 symptomatic patients.The majority of patients presented with abdominal pain(67%)combined with one of the following clinical categories:(1)Dyspepsia,(n=445,48%);(2)Pancreatitis(n=260,28%);(3)Gastrointestinal bleeding(n=80,9%);and(4)Gastric outlet obstruction(n=80,9%).The majority of cases(n=832,90%)underwent surgical or endoscopic resection with 85%reporting resolution or improvement in their symptoms.CONCLUSION Heterotopic pancreas can cause significant clinical symptoms in the upper gastrointestinal tract.Better understanding and classification of this disease may result in more accurate identification and treatment of this malformation. | Michael T Le Compte Brandon Mason Keenan J Robbins Motoyo Yano Deyali Chatterjee Ryan C Fields Steven M Strasberg William G Hawkins | 2022 | World Journal of Gastroenterology2022，28，14： | 3 |
| 5 | Prevalence of cholelithiasis in patients with chronic inflammatory bowel disease显示文摘AIM: To investigate the effect of chronic inflammatory bowel disease (CIBD) specific risk factors for cholecystolithiasis,as duration and involvement pattern of the disease and prior surgery in patients with Crohn's disease (CD) and ulcerative colitis (UC).METHODS: A total of 222 patients with CD (135 females,87 males; average age, 35.8±11.8 years; range 17-81 years)and 88 patients with UC (39 females, 49 males; average age, 37.2±13.6 years; range 16-81 years) underwent clinical and ultrasound examinations. Besides age, sex and degree of obesity, patients' CIBD specific parameters, including duration and extent of disease and prior operations were documented and evaluated statistically using logistic regression.RESULTS: The overall prevalence of gallbladder stone disease in patients with CD was 13% (n = 30). Only age could be shown to be an independent risk factor (P = 0.014).Compared to a collective representative for the general population in the same geographic region, the prevalence of cholecystolithiasis was higher in all corresponding age groups. Patients with UC showed an overall prevalence of gallbladder stone disease of only 4.6%.CONCLUSION:Only age but not disease-specific factors such as duration and extent of disease, and prior surgery are independent risk factors for the development of cholecystolithiasis in patients with CIBD. | Wolfgang Kratzer Mark M Haenle Richard A Mason Christian von Tirpitz Volker Kaechele | 2005 | World Journal of Gastroenterology2005，11，39： | 3 |
