| 1 | Sonographic gallbladder wall thickness measurement and the prediction of esophageal varices among cirrhotics显示文摘Acute variceal bleeding in patients with liver cirrhosis and portal hypertension(PHT) is the most serious emergency complication among those patients and could have catastrophic outcomes if not timely managed. Early screening by esophago-gastro-duodenoscopy(EGD) for the presence of esophageal varices(EVs) is currently recommended by the practice guidelines for all cirrhotic patients. Meanwhile, EGD is not readily accepted or preferred by many patients. The literature is rich in studies to investigate and validate non-invasive markers of EVs prediction aiming at reducing the unneeded endoscopic procedures. Gallbladder(GB) wall thickness(GBWT) measurement has been found promising in many published research articles. We aim to highlight the validity of sonographic GBWT measurement in the prediction of EVs based on the available evidence. We searched databases including Cochrane library, Pub Med, Web of Science and many others for relevant articles. GBWT is associated with the presence of EVs in cirrhotic patients with PHT of different etiologies. The cut-off of GBWT that can predict the presence of EVs varied in the literature and ranges from 3.1 mm to 4.35 mm with variable sensitivities of 46%-90.9% and lower cutoffs in viral cirrhosis compared to non-viral, however GBWT > 4 mm in many studies is associated with acceptable sensitivity up to 90%. Furthermore, a relation was also noticed with the degree of varices and portal hypertensive gastropathy.Among cirrhotics, GBWT > 3.5 mm predicts the presence of advanced(grade Ⅲ-Ⅳ) EVs with a sensitivity of 45%, the sensitivity increased to 92% when a cut-off ≥ 3.95 mm was used in another cohort. Analysis of these results should carefully be revised in the context of ascites, hypoalbuminemia and other intrinsic GB diseases among cirrhotic patients. The sensitivity for prediction of EVs improved upon combining GBWT measurement with other non-invasive predictors, e.g., platelets/GBWT. | Mohamed H Emara Mariam Zaghloul Ibrahim F Amer Aya M Mahros Mohammed Hussien Ahmed Mahmoud A Elkerdawy Eslam Elshenawy Abdelrahman M Ahmed Rasheda Tarik I Zaher Mona Talaat Haseeb Emad Hassan Emara Hassan Elbatae | 2023 | World Journal of Hepatology2023，15，2： | 1 |
| 2 | Schistosomal(bilharzial)polyps:Travel through the colon and beyond显示文摘Schistosomiasis(bilharziasis)is a major neglected tropical disease.It is endemic in many tropical and subtropical communities.Schistosomal polyps(S.polyps)are not uncommon presentation of this infection.Although the colon is the most commonly affected organ,many other organs are affected.S.polyps are associated with a variable range of morbidity independent of the Schistosomal infection.S.polyps are frequently described in endemic areas and increasingly reported in non-endemic areas mainly among immigrants and visitors to the endemic areas.This review aimed to increase awareness of practitioners,especially gastroenterologists,for this peculiar type of polyps caused by this neglected infection hence improving patient outcomes.Web-based search of different databases was conducted for the literature focusing the development of S.polyps in the colon and other organs with analysis of the clinical manifestations,diagnosis and treatment.The following key words were used in the search,“Schistosomiasis”OR“Bilharziasis”AND“Polyps”OR“Polyp”AND“Colon”OR“Small intestine”OR“Duodenum”OR“Stomach”OR“Esophagus”OR”Gallbladder”OR”Pharynx”OR“Larynx”OR“Trachea”OR”Urinary bladder”OR“Ureter”OR“Renal Pelvis”OR“Urethra”.All publication types including case reports,case series,original research,and review articles were retrieved and analyzed.S.polyps are not infrequent presentation of acute or chronic Schistosomal infection.S.polyps are described in many organs including the bowel,genitourinary tract,skin,gallbladder and the larynx.Presentation of S.polyps is variable and depends on the site,number as well as the polyp size.The relationship of S.polyps to malignant transformation is a matter of discussion.Presence of S.polyps is sometimes the only manifestation of Schistosomiasis.Small polyps can be treated medically with praziquantel,while large accessible polyps are amendable for endoscopic excision through different polyp resection techniques.However,huge,complicated,non-accessible and suspicious polyps are indicated for surgical management or advanced endoscopic resection when appropriate.Clinicians and endoscopists should be aware about these facts when treating patients living in,immigrated from or visiting endemic areas. | Mohamed H Emara Aya M Mahros Abdelrahman M Ahmed Rasheda Mohamed I Radwan Besher Mohamed Osama Abdelrazik Mostafa Elazab Hassan Elbatae | 2023 | World Journal of Gastroenterology2023，29，26： | 0 |
