Gallbladder perforations are categorized on the basis of the Niemeier classification. The therapeutic modality depends on the type of perforation. In this editorial, we present the actual guidelines and the findings from trials related to this issue. Moreover, we propose a pragmatic pathway that is based on clinical evidence. The following research gaps are identified: Randomized controlled trials aiming to compare emergency laparoscopic cholecystectomy with PTC as a bridge in cases of Niemeier I and Niemeier II disease are lacking; there are no standardized criteria for the use of PTC as a definitive therapy, such as frailty, sarcopenia or other markers; and there are no comparative studies of endoscopic ultrasound-guided gallbladder drainage <i>vs</i> PTC in cases of perforation.</p>","PeriodicalId":23759,"journal":{"name":"World Journal of Gastrointestinal Surgery","volume":"18 1","pages":"114059"},"PeriodicalIF":1.7,"publicationDate":"2026-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12898118/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146202931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
