    Interventional procedures consultation document

    Acute calculous cholecystitis happens when a gallstone blocks an opening (the cystic duct) that drains fluid (bile) from the gallbladder. Bile builds up in the gallbladder causing pain, nausea, vomiting and fever. In this procedure, a stent is inserted into or across the cystic duct, through the catheter that was inserted into the gallbladder through the skin (percutaneous cholecystostomy) to relieve the acute cholecystitis. The aim is to allow bile to flow through the tube, bypassing the blockage and preventing further obstruction.

    NICE is looking at percutaneous insertion of a cystic duct stent after cholecystostomy for acute calculous cholecystitis.

    NICE's interventional procedures advisory committee met to consider the evidence and the opinions of professional experts, who are consultants with knowledge of the procedure.

    This document contains the draft guidance for consultation. Your views are welcome, particularly:

    • comments on the draft recommendations

    • information about factual inaccuracies

    • additional relevant evidence, with references if possible.

    NICE is committed to promoting equality of opportunity, eliminating unlawful discrimination and fostering good relations between people with particular protected characteristics and others.

    This is not NICE's final guidance on this procedure. The draft guidance may change after this consultation.

    After consultation ends, the committee will:

    • meet again to consider the consultation comments, review the evidence and make appropriate changes to the draft guidance

    • prepare a second draft, which will go through a resolution process before the final guidance is agreed.

    Please note that we reserve the right to summarise and edit comments received during consultation or not to publish them at all if, in the reasonable opinion of NICE, there are a lot of comments or if publishing the comments would be unlawful or otherwise inappropriate.

    Closing date for comments: 2 November 2021

    Target date for publication of guidance: March 2022
