1. Transabdominal ultrasound and endoscopic ultrasound for diagnosis of gallbladder polyps. (PubMed)

Transabdominal ultrasound and endoscopic ultrasound for diagnosis of gallbladder polyps. Approximately 0.6% to 4% of cholecystectomies are performed because of gallbladder polyps. The decision to perform cholecystectomy is based on presence of gallbladder polyp(s) on transabdominal ultrasound (TAUS) or endoscopic ultrasound (EUS), or both. These polyps are currently considered for surgery if they grow more than 1 cm. However, non-neoplastic polyps (pseudo polyps) do not need surgery, even when (...) they are larger than 1 cm. True polyps are neoplastic, either benign (adenomas) or (pre)malignant (dysplastic polyps/carcinomas). True polyps need surgery, especially if they are premalignant or malignant. There has been no systematic review and meta-analysis on the accuracy of TAUS and EUS in the diagnosis of gallbladder polyps, true gallbladder polyps, and (pre)malignant polyps.To summarise and compare the accuracy of transabdominal ultrasound (TAUS) and endoscopic ultrasound (EUS) for the detection

10. Endoscopic ultrasound-guided gallbladder drainage for acute cholecystitis with a lumen-apposing metal stent: a systematic review of case series.

Endoscopic ultrasound-guided gallbladder drainage for acute cholecystitis with a lumen-apposing metal stent: a systematic review of case series. Management of patients with acute cholecystitis unfit for surgery is challenging. Recently, endoscopic ultrasound (EUS)-guided gallbladder drainage with a lumen-apposing metal stent (LAMS) has been introduced for these patients. We performed a systematic review and pooled-data analysis in this field. A comprehensive review of case series on gallbladder (...) % (95% CI=93.7-99) at per-protocol analysis. A total of 24 (10.6%) adverse events occurred, including 11 (4.9%) cases during the procedure, and 13 (5.7%) observed at follow-up (median=6 months; range: 2-12 months). A surgical approach was required in only 25% of patients with a major adverse event. No case of procedure-related death was reported. EUS-guided LAMS placement for gallbladder drainage in patients with acute cholecystitis not suitable for surgery is highly successful and acceptably safe.

11. Gallbladder ascariasis in Kosovo – focus on ultrasound and conservative therapy: a case series (PubMed)

Gallbladder ascariasis in Kosovo – focus on ultrasound and conservative therapy: a case series Ascaris lumbricoides is one of the most common intestinal infections in developing countries, including Kosovo. In contrast to migration to the bile duct, migration of the worm to the gallbladder, due to the narrow and tortuous nature of the cystic duct, is rare. When it does occur, it incites acalculous cholecystitis.This case series describes a 16-month-old Albanian girl, a 22-month-old Albanian (...) and spleen were not palpable. A laboratory examination was not specific except for eosinophilia. There were no pathogenic bacteria in coproculture but Ascaris was found in all patients. At an ultrasound examination in all cases we found single, long, linear echogenic structure without acoustic shadowing containing a central, longitudinal anechoic tube with characteristic movement within the gallbladder. Edema of the gallbladder wall was suggestive of associated inflammation. There were no other findings
