Background Endoscopic ultrasound-guided liver biopsy (EUS-LB) using a 19-gauge (19-G) EUS needle is becoming increasingly popular. We evaluated the efficacy and safety of a 22-G EUS fine needle biopsy (FNB) needle for performing EUS-LB.
Methods Patients referred for evaluation of elevated liver enzymes and without obstructive disease requiring endoscopic retrograde cholangiopancreatography (ERCP) were included. Using a 22-G FNB needle, two passes were made from the left lobe and one from the right. The main outcome measure was adequacy of the specimen for histology interpretation, and the secondary outcome was the safety of EUS-guided liver biopsy with a 22-G FNB needle. Patients were followed for post-procedure complications for 30 days.
Results 40 patients (median age 61 years; 26 women) underwent EUS-LB. Analyzing by needle passes, the median longest core fragment was 12 mm (1st quartile – 3rd quartile 10 mm – 16.25 mm, interquartile range [IQR] 6.25 mm) from the left lobe and 11 mm (10 mm – 15.75 mm, IQR 5.75 mm) from the right lobe. The median cumulative core length per patient was 55 mm (44.5 mm – 68 mm, IQR 23.5 mm). The median cumulative number of complete portal triads (CPTs) per patient was 42 (28.5 – 53, IQR 24.5). The specimen was considered adequate in all 40 patients (100 %). Self-limiting abdominal pain was reported in 6 patients (15 %).
Conclusions EUS-LB using a 22-G FNB needle is a safe and viable alternative to the use of larger gauge needles, yielding adequate tissue for evaluation of parenchymal disease in 100 % of the patients.
Intussusception typically occurs in infants and children, with adults representing 5% of cases. A 53-year-old African American woman presented with lower abdominal pain and tenderness. Computed tomography of the abdomen and pelvis demonstrated a 3.5 cm colocolonic intussusception in the descending colon. Emergent colonoscopy found solid stool in the mid descending colon. Water-soluble rectal enema showed a filling defect in the mid descending colon. Repeat colonoscopy demonstrated presence of a large fecaloma in left colon. Laxatives were initiated, and abdominal pain subsided. To our knowledge, this is the first report of colocolonic intussusception secondary to fecaloma.
Golimumab is a human IgG monoclonal antibody specific for human tumor necrosis factor alpha. Golimumab has been approved for use in rheumatological conditions; however, its use in inflammatory bowel disease is still being evaluated in clinical trials. We report a case of an exacerbation of ulcerative proctitis after starting on golimumab for ankylosing spondylitis.
Purpose of Review Gastrointestinal stromal tumors (GISTs) are both relatively common. Management of these lesions has been challenging with emerging interest in the endoscopic approach for both diagnostic and therapeutic interventions. Recent Findings Although these can be visualized on CT scan, endoscopic ultrasound (EUS) represents the standard method of evaluation and characterization using fine needle aspiration cytology (FNA) when indicated. While EUS-FNA can yield diagnostic cells, full characterization requires a sufficient volume of viable cells to do molecular analysis for c-KIT and determine the mitotic index. A new generation of fine needle biopsy (FNB) needles holds promise for improving our ability to fully characterize these lesions which will hopefully lead to improved management. Very small GISTs (< 1 cm) can probably be ignored, those between 1 and 2 cm are often surveyed, and those > 2 cm should be resected if the patient is fit and the lesion is in an accessible location. Though laparoscopic wedge resection is considered the standard of care, for small GISTs, those that are endophytic and/or located in a difficult position, pure endoscopic or hybrid laparoscopic-endoscopic approaches offer promise. Summary This review highlights the emerging advanced endoscopic approaches to GISTs. Although endoscopic removal of GISTs has two major advantages-precise localization of the lesion and gastric preservation, best practice strategies should focus on available expertise of expert endoscopists.
