Permanent Indwelling Transmural Stents for Endoscopic Treatment of Patients With Disconnected Pancreatic Duct Syndrome: Long-term Results.

INTRODUCTION: Disconnected pancreatic duct syndrome (DPDS) is defined as the complete disruption of the main pancreatic duct, the result are peripancreatic fluid collections or pancreatic leaks. The aim of this study was to report the results of derivative endoscopic treatment of DPDS in a long-term follow-up period. PATIENTS AND METHODS: We performed a retrospective analysis of prospectively collected data. Endoscopic treatment consisted of transmural drainage with 2 double pigtail plastic stents (7 F and 4 cm) deployed under endoscopic ultrasound guidance. RESULTS: In total, 21 patients were included in our study. There were 15 (71%) men and the median age was 36 years (range, 23 to 86 y). The principal etiology of DPDS was acute pancreatitis. A total of 20 (95.2%) patients were diagnosed with DPDS by endoscopic pancreatography and only 1 (4.8%) patient by magnetic resonance cholangiopancreatography (MRCP). The median follow-up time was 28 months (range, 7 to 76 mo). Technique success was 100% and initial clinical success was 80.9% (17/21). Three (17.6%) of these patients required a new endoscopic procedure with success in all cases. During follow-up, 11 (52%) patients developed diabetes mellitus and 3 patients (14%) developed exocrine pancreatic insufficiency. There were 5 (15%) patients with complications. CONCLUSION: According to our data, endoscopic treatment with the placement of a permanent indwelling transmural stents is a useful and safe tool for the treatment of DPDS.

Hepatic angiomyolipoma resected by eft hepatectomy: Case report.

El angiomiolipoma hepático es un tumor mesenquimatoso infrecuente perteneciente al grupo de los PEComas (Perivascular Epithelioid Cells), que cuenta con un potencial maligno indeterminado. Los síntomas clínicos son inespecíficos, siendo las características radiológicas principales la alta vascularización de la lesión y la presencia de tejido adiposo macroscópico. Presentamos un caso clínico de un angiomiolipoma hepático izquierdo diagnosticado por tomografía computada de manera incidental y asintomático en una paciente sin antecedentes de importancia que se sometió a hepatectomía lateral izquierda con resección completa del tumor, el cual fue negativo para malignidad y sin complicaciones.Hepatic angiomyolipoma is a mesenchymal tumor known as PEComas (Perivascular Epithelioid Cells) with unknown malignancy pattern. We present a case report of left hepatic angiomyolipoma diagnoses by computed tomography in an asymptomatic patient with no previous medical diseases. The tumor was complete resected during a left lateral hepatectomy with no complications and final histologic report was negative to cancer.
