RESUMO

[Purpose] This study aimed to examine the validity and reproducibility of a new quantitative method for measuring spinal kyphosis using computed tomography (CT), and to investigate its relationship with reflux esophagitis. [Method] Using a new method to measure the index of kyphosis in CT images (IKCT), 10 examiners evaluated 10 cases of spinal kyphosis. One examiner measured 47 cases twice and 20 cases were examined to assess the validity with the kyphosis index. A case-control study was conducted on 303 cases of reflux esophagitis, of which 241 were mild and 62 severe. [Results] Regarding IKCT reproducibility, the inter-rater intraclass correlation coefficient was 0.977. The intra-rater intraclass correlation coefficient was 0.974. The correlation index with the kyphosis index was 0.731. A greater IKCT value, not contracting serious atrophic gastritis, and severe hiatal hernia were identified as risk factors for severe reflux esophagitis. [Conclusion] IKCT is a simple and useful method for measuring kyphosis. The prevention of kyphosis can help suppress severe reflux esophagitis.

RESUMO

A 79-year-old man presented with high fever, marked eosinophilia, altered biochemical liver function tests (LFT) with predominance of biliary enzymes, and severe wall thickening of the gallbladder. Magnetic resonance cholangiopancreatography (MRCP) suggested cholecystitis, without signs of biliary strictures. Laparoscopic cholecystectomy and exploratory liver excision revealed eosinophilic cholangitis and cholecystitis, complicated with hepatitis and portal phlebitis. Prednisolone monotherapy rapidly improved peripheral eosinophilia, but not LFT. Liver biopsy showed that infiltrating eosinophils were replaced by lymphocytes and plasma cells. Treatment with ursodeoxycholic acid improved LFT abnormalities. Nevertheless, after 2 months, transaminase-dominant LFT abnormalities appeared. Transient prednisolone dose increase improved LFT, but biliary enzymes' levels re-elevated and jaundice progressed. The second and third MRCP within a 7-month interval showed rapid progression of biliary stricture. The repeated liver biopsy showed lymphocytic, not eosinophilic, peribiliary infiltration and hepatocellular reaction to cholestasis. Eighteen months after the first visit, the patient died of hepatic failure. Autopsy specimen of the liver showed lymphocyte-dominant peribiliary infiltration and bridging fibrosis due to cholestasis. Though eosinophil-induced biliary damage was an initial trigger, repeated biopsy suggested that lymphocytes played a key role in progression of the disease. Further studies are needed to elucidate the relationship between eosinophils and lymphocytes in eosinophilic cholangitis.

RESUMO

Endoscopic submucosal dissection (ESD) might be difficult to perform in some cases even for experienced endoscopists. Recently, various traction methods have been introduced to facilitate ESD procedures, such as clip-with-line (CL), external forceps, clip and snare, internal traction, double scope, and magnetic anchor. The traction procedure using the CL method enhances the visibility of the operation field during ESD. The original CL method is performed as follows: the clip with the line (e.g., dental floss) is attached to the edge of the lesion. Traction can be produced by pulling the line gently, thus achieving a sufficient visualization of the submucosal layer to identify an accurate cutting line. Herein, we present a useful modified two-CL method by pulling the appropriate normal mucosa to enhance the visibility of the operation field during ESD procedure. Thus, the traction methods, including our modified CL technique, might reduce the procedure time and complications.
