We performed endoscopic ultrasound (EUS-)guided celiac plexus neurolysis (CPN), because of recurrent abdominal pain resistant to analgesic drugs, in a 39-year-old woman with a diagnosis of pancreatic cancer that was unamenable to surgical treatment [1]

[5]. No immediate complications occurred. The patient was referred 7 days later, because of persistent abdominal pain radiating through the back, associated with night fever. Transabdominal echo tomography showed a hypoechogenic area 60 mm in diameter with small internal hyperechogenic spots, that was located between the pancreatic body and the celiac tripod and suggestive of an abscess.
In an attempt to drain the collection we carried out EUS, using an echo endoscope with a curved transducer array connected to an echo tomography device; this showed a shortest distance of 10 mm between the peripancreatic collection and the gastric wall, with no intervening vessels seen at a power Doppler examination. A needle-knife was introduced through the operative channel of the echo endoscope to puncture the collection (Figure [1]). At the end of the procedure, we introduced ceftazidime 1 g/10 ml, and estimated that the collection had been reduced to approximately 30 mm in diameter (Figure [2]).

The results of bacteriological examination demonstrated the presence of Citrobacter freundii and Pseudomonas aeruginosa, both sensitive to imipenem. Transabdominal echo tomography performed 4 days later demonstrated the complete disappearance of the fluid collection, and this was confirmed a further 5 days later by upper abdominal computed tomography (CT). Transabdominal ultrasound was done weekly in the next 3 months of follow-up and showed no recurrence of peripancreatic fluid collection.
Many authors consider CPN to be a technique that can be routinely performed as an outpatient procedure, rarely necessitating hospitalization. However, our experience with this new complication may suggest that patients should be admitted into hospital for EUS-CPN, with the aim of administration of broad-spectrum antibiotic therapy, both before and after the procedure, to prevent complications such as the abscess described here.
