Insights
Previous abdominal surgery in infants with biliary atresia (BA) is linked to poorer outcomes, despite potential for earlier diagnosis. Routine gallbladder checks during surgery may aid BA detection but do not improve survival rates.
Area of Science:
- Pediatric Surgery
- Hepatology
- Neonatal Care
Background:
- Biliary atresia (BA) diagnosis and treatment typically involve Kasai portoenterostomy (KPE), with outcomes related to surgical timing.
- Previous abdominal surgery (PAS) for congenital intestinal conditions may offer an opportunity for earlier BA identification and improved prognosis.
Purpose of the Study:
- To investigate if previous abdominal surgery (PAS) in infants with biliary atresia (BA) impacts diagnosis timing and clinical outcomes.
- To assess the effectiveness of routine gallbladder examination during PAS for early BA detection.
Main Methods:
- Retrospective review of 257 BA patients from 1999-2016.
- Collected demographics, clinical outcomes, and specific data for patients with PAS, including laparotomy, parenteral nutrition, and referral details.
- Classified as a prognostic study (Level III evidence).
Main Results:
- 16 (6.2%) infants underwent PAS; 5 had atretic gallbladders noted during surgery.
- Age at KPE was similar between PAS and non-PAS groups (50 vs. 51 days).
- Native liver survival was significantly lower (p<0.0001) and mortality higher (25% vs. 4.5%) in the PAS group.
Conclusions:
- Approximately 6% of BA infants have prior abdominal surgery for associated anomalies.
- Routine gallbladder inspection during laparotomy could aid early BA diagnosis in many cases.
- Prior abdominal surgery is associated with poorer clinical outcomes in biliary atresia patients, irrespective of earlier referral.
Background:
Biliary atresia (BA) is typically treated by Kasai portoenterostomy (KPE), and there is a relationship between age at surgery and outcome. We hypothesize that previous abdominal surgery (PAS) for associated congenital intestinal conditions could be used to identify BA earlier, perhaps improving prognosis.
Methods:
A retrospective case note review was performed of all BA patients at a single centre from 1999 to 2016. Demographics and clinical outcome data were collected. Additional data on laparotomy, parenteral nutrition, and referral were collected from patients who underwent PAS. Data are median (range).
Main Results:
Two-hundred-and-fifty-seven children were reviewed. Of these, 16 (6.2%) underwent PAS on day 3 (0-23), during which 5 atretic gallbladders were noted. Gallbladder appearance was not referenced in the operation notes of 8 infants. Jaundice and acholic stools were noted at 4 (0-56) days and 21 (0-60) days, respectively. Age at KPE was comparable between PAS and the other patients (50 vs. 51days; P=0.78), but native liver survival was significantly lower after PAS (p<0.0001). Mortality rate was higher in PAS patients (25% vs. 4.5%; P=0.0007). Survival was unaffected by early referral of patients on finding an atretic gallbladder at surgery.
Conclusion:
About 6% of infants have already undergone abdominal surgery for biliary atresia associated intestinal anomalies. Routine gallbladder examination at time of laparotomy could have aided earlier diagnosis and treatment of biliary atresia in up to 80% of patients in this cohort. However, our data suggest that clinical outcome is poorer in biliary patients who undergo prior abdominal surgery and is not improved by earlier referral.
Level Of Evidence:
Prognostic study: Level III.
