Insights

Centralizing pediatric liver tumor surgery in Switzerland significantly reduced postoperative complications and hepatic recurrence. This improvement in care highlights the benefits of specialized surgical centers for children.

Area of Science:

  • Pediatric Surgery
  • Surgical Oncology
  • Hepatobiliary Surgery

Background:

  • Pediatric liver surgery presents significant challenges with frequent complications.
  • Centralizing highly specialized surgical procedures can enhance patient care quality.
  • Switzerland established a national center for pediatric liver surgery in 2012.

Purpose of the Study:

  • To analyze the outcomes of pediatric liver tumor surgery before and after centralization.
  • To evaluate the impact of a national center on surgical complication rates and recurrence.
  • To assess changes in postoperative outcomes following the centralization of pediatric liver surgery.

Main Methods:

  • Retrospective monocentric comparative study analyzing medical records.
  • Inclusion of pediatric patients (0-16 years) operated for liver tumors between 2001 and 2020.
  • Comparison of 14 patients before centralization (pre-2012) and 27 patients after centralization (post-2012).

Main Results:

  • Overall postoperative complication rate significantly decreased from 57% to 15% (p=0.01).
  • Severe complications (Clavien > III) reduced from 50% to 7% (p<0.01).
  • Hepatic recurrence rates significantly dropped from 40% to 5% (p=0.03).

Conclusions:

  • Centralization of pediatric liver tumor surgery in Switzerland improved care quality.
  • The national center model led to significant reductions in postoperative complications.
  • Centralization also resulted in a significant decrease in hepatic recurrence rates.
