1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Introduction: The peribiliary gland is an accessory bile duct gland. Hyperplasia of these tissues may lead to elevation of the mucosa in the bile ducts and bile duct stenosis. We herein report a case of peribiliary gland hyperplasia that required preoperative differentiation from bile duct cancer, with a discussion of the literature. Case Presentation: The patient had an adenomatous lesion in the ascending colon that was difficult to treat endoscopically; therefore, surgery was planned. Preoperative abdominal ultrasonography revealed a bile duct tumor, and endoscopic ultrasonography revealed a mass lesion around the confluence of the cystic duct. Computed tomography revealed localized wall thickening in the middle bile duct, and the upstream bile ducts were slightly dilated. In addition, continuous thickening of the bile duct wall from the gallbladder to the confluence of the cystic duct was observed. No distant metastases, such as liver metastases, or nearby enlarged lymph nodes were observed. Endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography revealed a papillary-like elevated lesion in the bile duct near the confluence of the cystic duct, and a biopsy and bile cytology from the same area showed no malignant findings. As a result, the possibility that the patient had gallbladder or bile duct cancer could not be ruled out; therefore, a policy of surgery together with the ascending colon tumor was decided after receiving sufficient informed consent. During surgery, the patient underwent extrahepatic bile duct resection, reconstruction of the biliary tract using the Roux-en-Y method, and right hemicolectomy. Both duodenal and hilar bile duct transects were subjected to a fast frozen section analysis during surgery, and the results were negative for cancer. A histopathological examination of the resected specimen revealed no malignant findings in the bile duct lesions, and a diagnosis of peribiliary gland hyperplasia with chronic inflammatory cell infiltration and fibrosis of the extrahepatic bile duct wall was made. Conclusions: We encountered a case of peribiliary gland hyperplasia that was difficult to distinguish from bile duct cancer.
