Video assisted thoracoscopic surgery (VATS) can visualise malpositioned screws and resolve injury. This report presents a case of an AIS patient who underwent prone VATS for simultaneous screw correction after posterior spinal fusion. While traditional VATS uses a double lumen tube (DLT) in the lateral decubitus position, DLTs are less ideal for prone surgery. Bronchial blockers (BB), like the EZ-Blocker (Teleflex, Wayne, Pennsylvania), can be used with a more stable armoured single lumen tube (SLT). The EZ-Blocker, a Y-shaped BB, offers stability and sequential lung isolation. Studies show EZ-Blocker performance is comparable to DLTs in lung isolation quality and surgeon satisfaction, though it requires longer placement time and offers limited suctioning.

Treatment with prednisolone was initiated promptly, leading to progressive resolution of liver failure. Positive autoantibodies and liver histology confirmed the diagnosis.

GLP-1 agonists may be implicated in pancreatitis development mainly due to their effect on biliary motility and pancreatic cell proliferation. While causation remains unproven, it could be possible that GLP-1 induced pancreatic hypertrophy might influence cell metabolism and antigen presentation in predisposed individuals, altering the immunological milieu and eventually leading to type 1 AIP.
