International Delphi consensus on the management of percutaneous choleystostomy in acute cholecystitis (E-AHPBA, ANS, WSES societies).

BACKGROUND

There has been a progressive increase in the use of percutaneous cholecystostomy (PC) in acute cholecystitis (AC) over the last decades due to population aging, and the support of guidelines (Tokyo Guidelines (TG), World Society of Emergency Surgery (WSES) Guidelines) as a valid therapeutical option. However, there are many unanswered questions about the management of PCs. An international consensus on indications and PC management using Delphi methodology with contributions from experts from three surgical societies (EAHPBA, ANS, WSES) have been performed.

METHODS

A two-round Delphi consensus, which included 27 questions, was sent to key opinion leaders in AC. Participants were asked to indicate their 'agreement/disagreement' using a 5-point Likert scale. Survey items with less than 70% consensus were excluded from the second round. For inclusion in the final recommendations, each survey item had to have reached a group consensus (≥ 70% agreement) by the end of the two survey rounds.

RESULTS

54 completed both rounds (82% of invitees). Six questions got > 70% and are included in consensus recommendations: In patients with acute cholecystitis, when there is a clear indication of PC, it is not necessary to wait 48 h to be carried out; Surgery is the first therapeutic option for the TG grade II acute cholecystitis in a patient suitable for surgery; Before PC removal a cholangiography should be done; There is no indication for PC in Tokyo Guidelines (TG) grade I patients; Transhepatic approach is the route of choice for PC; and after PC, laparoscopic cholecystectomy is the preferred approach (93.1%).

CONCLUSIONS

Only six statements about PC management after AC got an international consensus. An international guideline about the management of PCs are necessary.
