Insights

Delayed elective resection is a safe option for most antenatally detected enteric duplication cysts. While many remain asymptomatic, the presence of gastric mucosa necessitates eventual surgical removal.

Area of Science:

  • Pediatric Surgery
  • Fetal Medicine
  • Gastrointestinal Surgery

Background:

  • Antenatal detection of intraabdominal cysts is increasing.
  • Enteric duplication cysts are a subset of these antenatally detected anomalies.

Purpose of the Study:

  • To evaluate the outcomes of delayed elective resection for antenatally detected enteric duplication cysts.
  • To assess the risks associated with expectant management versus early intervention.

Main Methods:

  • Retrospective case note review of 37 fetuses with intraabdominal cysts.
  • Analysis of 12 cases identified as enteric duplications (duodenal, jejunoileal, ileocecal).
  • Evaluation of outcomes following serial ultrasound monitoring and elective resection of asymptomatic cysts.

Main Results:

  • Three neonates required emergency laparotomy due to small bowel obstruction.
  • One ileocecal duplication became symptomatic at 2 months, necessitating laparotomy.
  • Seven asymptomatic duplications were electively resected between 6 weeks and 14 months; four contained gastric mucosa.

Conclusions:

  • Most intraabdominal enteric duplication cysts detected antenatally remain asymptomatic for a period, allowing for planned elective resection.
  • The presence of gastric mucosa in resected cysts indicates a potential risk, advising against indefinite observation.
  • Laparoscopically assisted resection of ileocecal duplications is a safe and effective surgical approach.
