Mirizzi syndrome is a rare complication of gallbladder disease that can be difficult to treat. In particular, endoscopic treatment often fails because of the inability to access or to capture the impacted cystic duct stone. We report a case of Mirizzi syndrome grade III that was successfully managed by digital single-operator peroral cholangioscopy-guided electrohydraulic lithotripsy with endoscopic nasogallbladder drainage and interval laparoscopic cholecystectomy. Based on our experience, digital single-operator peroral cholangioscopy-guided electrohydraulic lithotripsy with endoscopic nasogallbladder drainage is a feasible minimally invasive approach for the management of high-grade Mirizzi syndrome.

Spontaneous rupture of a hemorrhagic pancreatic pseudocyst may be life-threatening. Endoscopic ultrasound (EUS)-guided drainage has been reported to be a valuable treatment option for pancreatic pseudocysts. However, its usefulness in the management of a ruptured pancreatic pseudocyst is limited. We report a rare case of a spontaneous rupture of a hemorrhagic pancreatic pseudocyst in a patient with chronic pancreatitis, which was successfully treated with EUS-guided gastrocystostomy with a fully covered self-expandable metallic stent.

OBJECTIVE: The sub-axial injury classification (SLIC) and severity scale was developed to decide whether to operate the cervical injured patient or not, but the reliability of SLIC and severity scale among the different physicians was not well known. Therefore, we evaluated the reliability of SLIC among a spine surgeon, a resident of neurosurgery and a neuro-radiologist. METHODS: In retrograde review in single hospital from 2002 to 2009 years, 75 cases of sub-axial spine injured patients underwent operation. Each case was blindly reviewed for the SLIC and severity scale by 3 different observers by two times with 4 weeks interval with randomly allocated. The compared axis was the injury morphology score, the disco-ligamentous complex score, the neurological status score and total SLIC score; the neurological status score was derived from the review of medical record. The kappa value was used for the statistical analysis. RESULTS: Interobserver agreement of SLIC and severity scale was substantial agreement in the score of injury morphology [intraclass correlation (ICC)=0.603] and total SLIC and severity sacle (ICC value=0.775), but was fair agreement in the disco-ligamentous complex score (ICC value=0.304). Intraobserver agreements were almost perfect agreement in whole scales with ICC of 0.974 in a spine surgeon, 0.948 in a resident of neurosurgery, and 0.963 in a neuro-radiologist. CONCLUSION: The SLIC and severity scale is comprehensive and easily applicable tool in spine injured patient. Moreover, it is very useful tool to communicate among spine surgeons, residents of neurosurgery and neuro-radiologists with sufficient reproducibility.

IgG4-related autoimmune pancreatitis (IgG4-AIP) is an immune-mediated disease that can present as recurrent acute pancreatitis with biliary involvement. We report a case of a 55-year-old male with recurrent acute pancreatitis and obstructive jaundice of unknown cause. Laboratory tests revealed elevated IgG and IgG4 levels, while imaging showed pancreatic swelling, main pancreatic duct stricture, and distal bile duct stenosis. Endoscopic ultrasound-guided biopsy confirmed IgG4-positive plasma cell infiltration and fibrosis, leading to a diagnosis of IgG4-AIP. The patient responded well to corticosteroid therapy, with clinical and radiologic improvement, and was placed on low-dose maintenance therapy to prevent recurrence. IgG4-AIP should be considered in patients with idiopathic recurrent pancreatitis, and early recognition is crucial to avoid unnecessary interventions. Corticosteroids remain the mainstay of treatment, but long-term monitoring is essential due to the risk of recurrence and potential complications.
