Insights
Japanese pediatric surgeons are divided on prophylactic appendectomy during Ladd's procedure for midgut volvulus. Decisions balance future diagnostic clarity against risks of unnecessary surgery.
Area of Science:
- Pediatric Surgery
- Surgical Procedures
- Gastrointestinal Surgery
Background:
- Ladd's procedure is a key surgical intervention for midgut volvulus.
- The role of prophylactic appendectomy during Ladd's procedure remains debated.
- Institutional practices vary regarding routine appendectomy in neonates.
Purpose of the Study:
- To document Japanese institutional strategies for prophylactic appendectomy during Ladd's procedure.
- To identify the rationales and exceptions guiding these surgical decisions.
- To understand the current landscape of this surgical practice in Japan.
Main Methods:
- A cross-sectional questionnaire survey was distributed to pediatric surgical institutions in Japan.
- Institutions reported their approach to prophylactic appendectomy in a standardized scenario of emergency Ladd's procedure.
- Responses from 45 institutions were analyzed descriptively.
Main Results:
- Nearly half of responding institutions (48.9%) routinely perform prophylactic appendectomy during Ladd's procedure; 51.1% do not.
- Reasons for performance include preventing future appendicitis and diagnostic confusion.
- Reasons for non-performance focus on advanced imaging and avoiding unnecessary procedures.
Conclusions:
- Japanese institutions exhibit standardized yet differing approaches to prophylactic appendectomy in Ladd's procedure.
- These findings highlight the balance between diagnostic, operative, and reconstructive considerations.
- Provides a basis for protocol refinement and outcome-based research in pediatric surgery.
Purpose:
To describe institutional approaches to prophylactic appendectomy during Ladd's procedure in Japan, including rationales and prespecified exceptions.
Methods:
We conducted a cross-sectional questionnaire survey through the Japanese Society of Pediatric Surgeons Under-45 Working Group. Member institutions reported their usual institutional approach in a standardized index scenario of emergency Ladd's procedure for midgut volvulus in a stable term neonate without intestinal necrosis or perforation. Responses were analyzed descriptively.
Results:
Forty-six of 50 invited institutions responded; 45 with a unified institutional approach were analyzed. In the index scenario, 22 institutions (48.9%) reported routinely performing prophylactic appendectomy and 23 (51.1%) reported not performing it. Performance institutions most commonly cited avoidance of future diagnostic confusion (72.7%) and prevention of future appendicitis (68.2%), whereas non-performance institutions emphasized confidence in contemporary imaging (60.9%) and avoidance of unnecessary procedures or complications (47.8%). Among performance institutions, omission was mainly reported in the presence of intestinal necrosis, perforation, or very or extremely low birthweight; deviations from non-performance were rare.
Conclusion:
Japanese institutions show highly standardized yet divergent approaches to prophylactic appendectomy during Ladd's procedure. These findings clarify how diagnostic, operative, and future reconstructive considerations are balanced and provide a practical framework for protocol review and outcome-focused studies.
