Try ertapenem for 3 weeks

Sensitivity patterns are essential.

ESBL producing E. coli may be sensitive to piperacillin/tazobactam, carbapenems, phosphomycin, quinolones...

Infected colections rarely are solved with antibiotherapy alone. Some kind of drainage interventions are needed.

The patient received long time antibiotic therapy (months) including carbapenems (ertapenem, meropenem), and performed drainage (3-4 times). He is still on therapy with meropenem but without resolution. (See above: picture after drainage, large chest hematoma on the right). E. coli is still present into the pseudotumour.
