The inaccessible or undrainable
abscess: How to drain it.
 in 2017 found that for CD patients with percutaneously undrainable abscesses, the use of EEN was associated with a decreased need for surgery.

No indication requiring long-term parenteral antibiotic use: endocarditis, meningitis, central nervous system infection, osteomyelitis, prosthetic material infection, Staphylococcus aureus bacteraemia, undrained or undrainable
abscess and neutropenic fever 2.
The indications for emergency operative intervention in acute diverticulitis include the presence of generalised peritonitis, uncontained visceral perforation, gross uncontrollable sepsis, a large undrainable

French drains are temporary storage trenches that drain and hold small amounts of water in low, undrainable
As far as we know, there were no published studies in the current literature which determined the effect of EEN on outcomes in CD patients with percutaneously undrainable abscesses.
Treatments for the percutaneously undrainable abscesses were generally started with nutrition management and concomitant antibiotics.
During the follow-up period, the estimated cumulative rates of surgery for CD patients with undrainable abscess were 43% at 1 month, 61% at 3 months, 85% at 1 year, and 90% at 2 years.
In the present study, we found that EEN could be safely used in CD patients with percutaneously undrainable abdominal abscesses.
Despite this, our results represent the only report on the use of EEN in CD complicated by percutaneously undrainable abdominal abscess.
In conclusion, the results of our study confirm that EEN is the treatment of choice in patients with percutaneously undrainable abdominal abscesses in CD.
