A large mural nodule in branch duct intraductal papillary mucinous adenoma of the pancreas: a case report.

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.
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
Indications for resection of branch duct intraductal papillary mucinous neoplasms (IPMNs) remain controversial because of their low tendency to be malignant. Surgical resection should be recommended if any factors indicating malignancy are present. However, preoperative differentiation between benign and malignant tumors is very difficult, especially in cases of branch duct IPMNs. We herein report a case of branch duct intraductal papillary mucinous adenoma (IPMA) of the pancreas with a large mural nodule of 25 mm. A 74-year-old woman was admitted for examination and treatment for a cystic tumor in the head of the pancreas. Magnetic resonance cholangiopancreatography and computed tomography showed a cystic lesion, 50 mm in diameter, with an irregular mural nodule in the pancreatic head. Endoscopic ultrasonography demonstrated a multicystic tumor connected with the main pancreatic duct (MPD). The mural nodule had a diameter of 18 mm, and the MPD had a slight dilation of 6 mm. These findings suggested a high potential for malignancy. The patient underwent pancreaticoduodenectomy with lymph node dissection. The excised pancreas showed multiple cysts located in the branch pancreatic duct with a maximum diameter of 75 mm. The mural nodule had a maximum diameter of 25 mm. The tumor was diagnosed as an IPMA by pathological examination. After operation, the patient was discharged without any complications. Two years after resection, the patient remains in remission with no evidence of tumor recurrence.
