Abdominal pseudocysts (APCs) are rare complications of ventriculoperitoneal shunts, often linked to prior abdominal surgery and multiple revisions. This study analyzes 64 APC cases to simplify management strategies.

Area of Science:

  • Neurosurgery
  • Pediatric Surgery
  • Gastroenterology

Background:

  • Abdominal pseudocyst (APC) is an infrequent complication following ventriculoperitoneal (VP) shunt placement.
  • Predisposing factors include shunt infection, multiple shunt revisions, prior abdominal surgery, and necrotizing enterocolitis.
  • Effective management strategies for APC are complex and require careful consideration.

Purpose of the Study:

  • To review and analyze cases of abdominal pseudocyst (APC) in patients with VP shunts.
  • To identify predisposing factors and evaluate treatment outcomes for APC.
  • To develop a simplified algorithm for managing APC to improve patient outcomes.

Main Methods:

  • Retrospective review of shunt revisions over a 20-year period.

  • Analysis of 64 APC cases in 36 patients, examining infection history, prior abdominal surgery, necrotizing enterocolitis, and treatments.
  • Evaluation of treatment outcomes to inform the development of a management algorithm.
  • Main Results:

    • 64 cases of APC (46 primary, 18 recurrent) were identified in 36 patients.
    • 47% of patients had prior abdominal surgery (excluding shunt revisions), and 19% had a history of necrotizing enterocolitis.
    • Shunt infection was present in 23% of APC cases, with 30% having a history of prior shunt infection.

    Conclusions:

    • Abdominal pseudocysts are complex VP shunt complications often associated with prior abdominal interventions.
    • While infection is a factor, it is not universally present in APC cases.
    • A structured approach and algorithm can simplify the management of abdominal pseudocysts, improving outcomes.
