Biliary Atresia, Appendicitis, Intestinal Failure, and Anesthetic...
The START trial randomized 140 infants with biliary atresia to high-dose steroids (IV for 2 weeks, oral for 2 weeks, taper over 9 weeks) versus placebo within 72 hours of Kasai portoenterostomy.
Host summaryDaniel von Allmen summarizing the discussion — not the host's own clinical position2:48
The primary outcome was serum total bilirubin <1.5 mg/dL with native liver at 6 months post-Kasai; the study was powered to detect a 25% absolute treatment difference.
Host summaryDaniel von Allmen summarizing the discussion — not the host's own clinical position3:32
High-dose steroid therapy after Kasai did not result in a statistically significant treatment difference in bile drainage at 6 months: 58.6% in the steroid group versus 48.6% in placebo.
Host summaryDaniel von Allmen summarizing the discussion — not the host's own clinical position4:01
Survival without liver transplant at 24 months was not statistically different: 58.7% for steroids versus 49.4% for placebo.
Host summaryDaniel von Allmen summarizing the discussion — not the host's own clinical position4:39
Adverse events were common in both groups (near 80%), largely reflecting severe underlying liver dysfunction; steroid treatment was associated with earlier onset of serious adverse events.
Host summaryDaniel von Allmen summarizing the discussion — not the host's own clinical position4:55
Dr. von Almen personally used steroids after Kasai in the past but has stopped based on the START trial results.
Expert opinionDaniel von Allmen5:31
The authors of the START trial believe anything less than a 25% difference in bile drainage is not worth the potential early complications of steroids.
Host summaryDaniel von Allmen summarizing the discussion — not the host's own clinical position7:11
Two proposed mechanisms for steroid benefit in biliary atresia: reducing ongoing inflammation to preserve ductules, and acting as a choleretic to maintain bile flow (analogous to diuresis after kidney transplant).
The START trial specifically tested a 13-week course of high-dose steroids; the lack of benefit applies to that regimen.
A Washington State registry study of clean-contaminated adult general surgery cases (60% colorectal, 34% bariatric) found no single skin antiseptic agent associated with lower SSI risk than any other.

Isopropyl alcohol as part of the antiseptic mixture conferred no benefit: unadjusted SSI rate 4.5% without alcohol versus 4.6% with alcohol.
Host summaryWhit Holcomb summarizing the discussion — not the host's own clinical position13:49
The registry could not identify SSI diagnosed after discharge, likely underestimating the true SSI rate; a recent report showed 50% or more SSIs are diagnosed after discharge.
Host summaryWhit Holcomb summarizing the discussion — not the host's own clinical position14:20
Most SSIs occur 3–10 days after operation; average length of stay in the study was 6–7 days.

Dr. Holcomb's institution switched to chlorhexidine with isopropyl alcohol (chloraprep) except for mucous membrane preps (e.g., circumcision).
Most pediatric surgery cases are clean (not clean-contaminated), so the Washington State study does not directly address pediatric practice.
Expert opinionWhit Holcomb17:03
Chloraprep or similar agents dry faster than betadine/iodine preps, allowing cases to start sooner; this matters when doing 6–7 cases per day.
A pilot randomized trial in children aged 5–15 with non-perforated appendicitis (based on imaging) compared non-operative antibiotic treatment versus laparoscopic appendectomy; follow-up was one year.
Host summaryWhit Holcomb summarizing the discussion — not the host's own clinical position20:35
Of 225 children with appendicitis, 50 were randomized (26 to surgery, 24 to antibiotics); 77 families declined participation.
Host summaryWhit Holcomb summarizing the discussion — not the host's own clinical position22:42
In the antibiotic group, 2 of 24 underwent appendectomy during primary treatment, 1 had recurrent appendicitis at 9 months, and 6 more had appendectomy for recurrent pain or parental desire (none with histologic appendicitis)—total 9 of 24 (38% failure rate).
Host summaryWhit Holcomb summarizing the discussion — not the host's own clinical position23:14
Median time to discharge was significantly shorter in the surgical group, but the antibiotic group had a stipulated 48-hour minimum hospitalization.
Host summaryWhit Holcomb summarizing the discussion — not the host's own clinical position24:35
Cost for the initial inpatient stay was significantly lower in the antibiotic group despite longer hospitalization, highlighting the cost of undergoing an operation.
Host summaryWhit Holcomb summarizing the discussion — not the host's own clinical position24:55
The pilot study demonstrates that a definitive randomized trial comparing antibiotics and laparoscopic appendectomy for non-perforated appendicitis is safe and feasible; a multi-center study is planned.

Dr. Holcomb has not treated acute appendicitis non-operatively at his institution but knows of poor operative candidates treated successfully with antibiotics.
Expert opinionWhit Holcomb26:33
Immunosuppressed cancer patients with typhlitis (not appendicitis but similar) are sometimes treated non-operatively, and most resolve with antibiotics.
The challenge will be identifying which population of appendicitis patients can be treated successfully non-operatively versus which should undergo early operation.
Expert opinionWhit Holcomb27:22
Long-term follow-up is critical; even a 10-year follow-up leaves patients only 15–20 years old, with 40–50 years of life remaining at risk for recurrent appendicitis.
Expert opinionWhit Holcomb27:52
Some parents in the pilot study wanted their child's appendix removed to avoid future worry, even after successful antibiotic treatment.
Host summaryWhit Holcomb summarizing the discussion — not the host's own clinical position29:19
If appendectomy can be done as an outpatient same-day procedure, it may be difficult to argue for 1–2 days of antibiotics with uncertain long-term recurrence risk.

A PIFCON multi-center cohort study of 272 children with intestinal failure (median follow-up 33 months) found enteral autonomy was achieved in 43%, 13% remained PN-dependent, and 43% died or underwent transplant.
Host summaryAaron Lipskar summarizing the discussion — not the host's own clinical position31:31
Necrotizing enterocolitis as the underlying diagnosis, care at an intestinal rehab facility without a transplant center, and presence of an ileocecal valve were all statistically significantly associated with higher rates of enteral autonomy.
