ABSTRACT

Pancreatic tuberculosis (TB) is a rare but important entity to consider when evaluating a pancreatic mass, especially in patients from endemic areas. Its clinical and radiologic features may mimic those of a pancreatic neoplasm, making it a difficult clinical diagnosis. We present a case of a 31-year-old Indian man who presented with fevers, night sweats, weight loss, and epigastric pain. Abdominal magnetic resonance imaging (MRI) showed a pancreatic head mass. Biopsy of the mass was consistent with pancreatic tuberculosis.

ABSTRACT

We report a case of mucinous cystic neoplasm of pancreas with sarcomatous stroma metastasizing to the liver. The tumor occurred in a male patient aged 46 years. Symptoms included persistent epigastric and right upper quadrant pain. Radiographically, the pancreas contained four large cystic masses located in the neck, body, and tail. Histologically, the cysts were lined with benign, mucinous epithelium with underlying bland, storiform, ovarian-like stroma. An undifferentiated focally hyalinized, sarcomatous stroma composed of bland spindle cells showing short fascicular growth pattern and focal nuclear palisading was associated with the epithelial component in one of the cysts. These cells showed strong immunoreactivity with vimentin and inhibin (weak), they were negative for CD34, estrogen receptor, progesterone receptor, androgen, calretinin, S-100, CD117, melan A, chromogranin, and synaptophysin. A morphologically and immunohistochemically identical metastatic sarcomatous focus was identified in the liver without any glandular component. This case is unique in its clinically malignant behaviour and metastatic nature despite its morphologically benign epithelial and stromal components.

ABSTRACT

BACKGROUND: EUS-guided celiac plexus neurolysis (EUS-CPN) improves pain control in patients with pancreatic cancer. EUS allows visualization of the celiac ganglion. OBJECTIVE: To determine predictors of response to EUS-CPN in a cohort of 64 patients with pancreatic malignancy. DESIGN: Retrospective analysis of prospective database. SETTING: Academic medical center. PATIENTS: Sixty-four patients with pancreatic cancer referred for EUS between March 2008 and January 2010. INTERVENTIONS: EUS-CPN injected directly into celiac ganglia when visible by linear EUS or bilateral injection at the celiac vascular trunk. MAIN OUTCOME MEASUREMENTS: Predictors of pain improvement at week 1 by univariate and multivariate analysis. RESULTS: At week 1, 32 patients (50%) had a symptomatic response. In a multivariate model with 8 potential predictors, visualization of the ganglia was the best predictor of response; patients with visible ganglia were >15 times more likely to respond (odds ratio 15.7; P<.001). Tumors located outside the head of the pancreas and patients with a higher baseline pain level were weakly associated with a good response. LIMITATIONS: Retrospective design and lack of blinding. CONCLUSIONS: Visualization of celiac ganglia with direct injection is the best predictor of response to EUS-CPN in patients with pancreatic malignancy.

ABSTRACT

BACKGROUND: Endoscopic ultrasonography (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) often are required in the evaluation and treatment of patients with pancreaticobiliary disorders. Few reports of single-session EUS-ERCP have raised questions regarding its safety and accuracy or about which procedure should be performed first. METHODS: Data from 2005 to 2009 were reviewed from a prospectively maintained EUS-ERCP database at a single tertiary care cancer center. Sensitivity and specificity of EUS and fine-needle aspiration (FNA), bile duct cannulation rate, duration of procedure, and complications were evaluated. RESULTS: Of the 35 patients (15 men and 20 women) studied, 28 had a final diagnosis of malignancy, and 7 had benign disorders. All the patients underwent ERCP and EUS, with FNA performed for 28 patients (80%). For 22 of the 35 patients (62.8%), EUS was the first procedure performed. The sensitivity of EUS-FNA for malignancy was 96.4%. The bile duct cannulation rate during ERCP was 97.1%. Five patients required a precut sphincterotomy for bile duct access, and one patient with chronic pancreatitis had a failed cannulation despite a EUS-guided rendezvous. A stent was successfully placed in 29 patients (96%). No major complications occurred, and no contrast leak was seen when FNA was performed before the cholangiogram. One patient had periduodenal bleeding after FNA, which was managed conservatively. The mean duration of the procedure was 83.7 min. CONCLUSION: Single-session EUS-ERCP can be performed safely and with efficacy similar to that of the procedures performed separately.
