Abstract
Splenic injury is an extremely rare complication of endoscopic retrograde cholangiopancreatography (ERCP). There are only 34 cases reported in the literature up to now. Based on a case of a 72-year-old man, who after ERCP due to choledocholithiasis developed a large perisplenic and subcapsular hematoma, we carried out an extensive review of all cases of ERCP-induced splenic injury found in the literature. We searched PubMed/Medline and Google Scholar till 15 April 2023, for published case reports and series using the following terms: splenic injury after ERCP, ERCP-induced splenic injury, and post-ERCP splenic trauma. The case reports included were in English, Spanish, and German literature. We attempt to discuss the possible clinical image, the available diagnostic methods, the potential treatment alternatives, and predisposing factors related to this entity. Furthermore, a theory of a possible mechanism of this injury is discussed and supported schematically. The ERCP-induced splenic injury is rare and a high index of suspicion is needed for diagnosis. Therefore, we present two diagnostic algorithms, which according to our opinion may assist the evaluation of this complication and lead to early accurate diagnosis and appropriate management. Collectively, our findings support that although ERCP-induced splenic injury is an unexpected/unusual complication of ERCP, following the proper steps can be timely diagnosed and treated.
