The Use of Mucolytic Agent in Percutaneous Drainage of Liver Abscess: A Case-Series Analysis

Hepatic Abscess in Inflammatory Bowel Disease: A Systematic Scoping Review of an Overlooked Entity

Background

Liver abscess is one of the hepatobiliary manifestations of inflammatory bowel disease (IBD) that has been scarcely described in the literature.

Objectives

To conduct a scoping review to provide a detailed description of the occurrence of hepatic abscess in patients with IBD and summarize the observed clinical features.

Methodology

Searches were carried out using relevant keywords in Medline (via PubMed) and Web of Science from inception until June 13, 2022. Only articles that reported the occurrence of hepatic abscess in patients with IBD were included.

Results

Forty-eight publications (40 case reports and 8 case series) were included, representing 73 patients with IBD who were radiologically or intraoperatively diagnosed with hepatic abscess. Patients with Crohn's disease were more predisposed to developing hepatic abscess than patients with ulcerative colitis (79.5% vs. 20.5%, respectively). Furthermore, pyogenic liver abscess was found to be more prevalent (57.9%) compared with aseptic (38.7%) and amebic (3.2%) abscesses. No clear relation was found between death or prolonged hospital stay in terms of the clinical presentation or management plan, as mortality was reported in different age groups with different managements.

Conclusion

To date, there is no consensus regarding the appropriate management of hepatic abscess as an extraintestinal manifestation of IBD. However, the condition shares several features with liver abscess diagnosed among the general population.

Entrapped Malecot catheter removal: Our experience

Some surgeons use a Malecot catheter for drainage of intra-abdominal or mediastinal collections. These tubes are usually removed after 2-3 weeks. If left later, they may become entrapped due to the ingrowing of tissue, and fibrosis within the flower-like tip of the Malecot's catheter. Its removal then needs careful manipulation to prevent organ damage. We present our experience in ensuring the safe removal of such entrapped Malecot's catheters in liver abscess patients.
