Intra Abdominal fluid accumulation that needed surgical intervention in the past can now be evacuated using less invasive methods. The insertion of lumen-apposing metal stents (LAMS) to treat pancreatic pseudocysts and perirectal abscesses in adults has been demonstrated to be a safe and successful method. At this institution, researchers hope to assess the indications, results, and consequences of LAMS usage in paediatric patients. A retrospective chart analysis was conducted on kids up to the age of 18 at the Children’s Hospital at Montefiore who received LAMS drainage of intraabdominal fluid accumulation. The primary end indicators were technical and clinical success, as well as adverse events related with LAMS implantation. Seven cases, ranging in age from nine to eighteen years, were identified. Four individuals developed perirectal abscesses after ruptured appendicitis, and three had pancreatic pseudocysts. The technical and clinical success rate was 100 percent, and all of the patients had full clearance of the collections with no recurrence. Only one patient experienced little bleeding after implantation, which cleared on its own.

Despite the small number of patients involved, this study indicates the effectiveness and safety of using LAMS for the drainage of intraabdominal fluid accumulation in paediatric patients.
