The Use of Clips to Prevent Post-Polypectomy Bleeding: A Clinical Review.

GOALS: The goal of this clinical review is to provide an overview of the current literature regarding the utility of prophylactic clips in reducing postpolypectomy bleeding and to provide an expert statement regarding their appropriateness in clinical practice. BACKGROUND: Colonoscopy enables the identification and removal of premalignant and malignant lesions through polypectomy, yet complications including postpolypectomy bleeding (PPB) can arise. While various studies have explored applying clips prophylactically to prevent PPB, their effectiveness remains uncertain. STUDY: A literature search conducted in PubMed and Embase identified 671 publications discussing clip use postpolypectomy; 67 were found to be relevant after screening, reporting outcomes related to PPB. Data related to clip utilization, polyp characteristics, and adverse events were extracted and discussed. RESULTS: The current literature suggests that prophylactic clipping is most beneficial for nonpedunculated polyps ≥20 mm, especially those in the proximal colon. The utility of clipping smaller polyps and those in the distal colon remains less clear. Antithrombotic medication usage, particularly anticoagulants, has been linked to an increased risk of bleeding, prompting consideration for clip placement in this patient subgroup. While cost-effectiveness analyses may indicate potential savings, the decision to clip should be tailored to individual patient factors and polyp characteristics. CONCLUSIONS: Current research suggests that the application of prophylactic clips can be particularly beneficial in preventing delayed bleeding after removal of large nonpedunculated polyps, especially for those in the proximal colon and in patients on antithrombotic medications. In addition, for large pedunculated polyps prophylactic clipping is most effective at controlling immediate bleeding.

Therapeutic Banding for Bleeding Duodenal Lymphangiectasias: A Novel Approach.

With endoscopic advancements, the number of detected intestinal lymphangiectasias has been on the rise. They are generally considered benign and incidental; occasionally, these lesions carry complications, and best management options need to be established. Bleeding intestinal lymphangiectasias should be considered a rare cause in the differential diagnosis for gastrointestinal bleeding. References in the literature primarily indicate surgical treatment in these situations. In this study, we report an uncommon case of a man with esophageal adenocarcinoma who developed acute gastrointestinal bleeding from duodenal lymphangiectasias that were successfully banded.

Hepatic Amyloidosis With Multiorgan Involvement.

Amyloidosis is a diverse entity that poses both diagnostic and treatment challenges. Whether systemic or local, amyloidosis has varied manifestations including occasional hepatic involvement. Hepatic amyloidosis, although rare, should be on the differential for those with unexplained hepatomegaly, cholestasis, alkaline phosphatase elevations, other associated organomegaly, and those with certain epidemiologic risks. In this study, we report a case of a man with systemic amyloid light chain amyloidosis with multiorgan involvement, acute liver injury, cholestasis, nephrotic syndrome, cardiomegaly, and bleeding diathesis.

Severe Cholestatic Drug-Induced Liver Injury With Cephalosporin Use.

Drug-induced liver injury (DILI) is a phenomenon that occurs with nearly all classes of medications. Cholestatic DILI represents a fraction of these cases and can present as bland cholestasis, cholestatic hepatitis, secondary sclerosis cholangitis, and vanishing bile duct syndrome. Risk factors have been identified for cholestatic DILI, including older age, genetic determinants, and certain medications such as amoxicillin-clavulanate. Here, we describe a complicated case of severe cholestatic DILI secondary to cephalosporin use. A 27-year-old female presented to the hospital initially with fever and abdominal pain for four weeks after an emergency C-section for pre-eclampsia and hemolysis, elevated liver enzymes, lowered platelets (HELLP) syndrome. She was found to have a retroperitoneal abscess and underwent bilateral drain placement. She was initially started on cefazolin, and then coverage was broadened to cefepime. Shortly after, alkaline phosphatase (ALP) rose and peaked at 3498 IU/L, with aspartate aminotransferase (AST) and alanine transaminase (ALT) elevated at 274 IU/L and 122 IU/L, respectively. Extensive testing for secondary causes and a liver biopsy were consistent with DILI. Liver enzymes down-trended with the cessation of cefepime. This case report highlights that prompt recognition of the culprit medication is paramount to recovering normal liver function.
