RESUMEN
OBJECTIVES: To ascertain the prevalence of pancreatic cysts detected incidentally on 3-Tesla magnetic resonance imaging (MRI) of the abdomen and correlate this prevalence with patient age and gender; assess the number, location, and size of these lesions, as well as features suspicious for malignancy; and determine the prevalence of incidentally detected dilatation of the main pancreatic duct (MPD). METHODS: Retrospective analysis of 2,678 reports of patients who underwent abdominal MRI between January 2012 and June 2013. Patients with a known history of pancreatic conditions or surgery were excluded, and the remaining 2,583 reports were examined for the presence of pancreatic cysts, which was then correlated with patient age and gender. We also assessed whether cysts were solitary or multiple, as well as their location within the pancreatic parenchyma, size, and features suspicious for malignancy. Finally, we calculated the prevalence of incidental MPD dilatation, defined as MPD diameter ≥ 2.5 mm. RESULTS: Pancreatic cysts were detected incidentally in 9.3% of patients (239/2,583). The prevalence of pancreatic cysts increased significantly with age (p<0.0001). There were no significant differences in prevalence between men and women (p=0.588). Most cysts were multiple (57.3%), distributed diffusely throughout the pancreas (41.8%), and 5 mm or larger (81.6%). In 12.1% of cases, cysts exhibited features suspicious for malignancy. Overall, 2.7% of subjects exhibited incidental MPD dilatation. CONCLUSIONS: In this sample, the prevalence of pancreatic cysts detected incidentally on 3T MRI of the abdomen was 9.3%. Prevalence increased with age and was not associated with gender. The majority of cysts were multiple, diffusely distributed through the pancreatic parenchyma, and ≥ 5 mm in size; 12.1% were suspicious for malignancy. An estimated 2.7% of subjects had a dilated MPD.

Se realiza un estudio en 25 pacientes egresados del servicio de Cirugía General, a los cuales se les realiza pancreatectomía distal por padecer de alguna enfermedad susceptible de realizarle esta técnica quirúrgica, durante el periodo comprendido entre enero de 1982 y diciembre de 2012 (30 años). El dato primario es obtenido de las historias clínicas. Se estudia el sexo, edad, causas y complicaciones de esta técnica quirúrgica. La edad promedio es de 36 años con una DS ± 15 con un rango entre los 14-68 años. El sexo femenino predomina, los quistes epiteliales alcanzan el primer lugar en incidencia seguido por pancreatitis crónica. El muñón pancreático de los 25 pacientes se cerró de forma manual. Solo 1 paciente presentó una fístula pancreática (AU)
A study is done in discharged 25 patients from the General Surgery Service, which were applied distal pancreatectomy because of severe illnesses .this surgical procedure was applied from January 1982 to December 2012 (30 years). The primary data was obtained from the medical records. Variables were studied: sex, age, causes and complications of this surgical technique. The average age was 36 years with a SD ± 15 with a range between 14-68 years. The females were predominant, epithelial cysts reached first place in incidence followed by chronic pancreatitis. The pancreatic stump of the 25 patients was closed manually. Only one patient had a pancreatic fistula (AU)

BACKGROUND: Pancreatic cystic lesions (PCL) are identified in 1 % of patients who undergo abdominal computed tomography scans, because it is difficult to discriminate clinically between benign and malignant PCL. The PCL must be distinguished from inflammatory pseudocysts, which can have a similar radiographic appearance. The aim of this study was to review the incidence of PCL during 10 years. METHODS: Nineteen consecutive patients who underwent surgical resection of a cystic lesion of the pancreas during a 10-year period were reviewed. RESULTS: From 1998, 434 patients underwent to pancreatic surgery, 103 (25.75%) resulted with neoplasm of the pancreas and a PCL was diagnosed in 19 of them (18.44%). They were more common in women (n=15, 79%). The pathologic diagnosis was mucinous cystadenoma (n=6, 31.5%) followed by serous cystadenoma and solid cystic papilar tumor (n=4, 21%). Mucinous cystadenocarcinoma was diagnosed in a 77 year-old man and a serous cystadenocarcinoma was diagnosed in a 53 years-old woman; cystic degeneration of two insulinomas were diagnosed in a 71 year-old woman and a 32 year-old man (5.26%). CONCLUSIONS: PCLs represent a spectrum of associated diseases. The incidence of serous cystadenoma is lower in our experience.

The aim of this report was to describe the clinical and pathologic features of lymphoepithelial cysts of the pancreas, establish the differential diagnosis of other pancreatic cysts, and review the literature. A 53-year-old man was incidentally diagnosed with a pancreatic lesion after an abdominal CT scan. This study showed a solid mass in the tail of the pancreas not enhanced by helical CT. Endoscopic ultrasound examination revealed a low-density tissue mass on the surface of the pancreas, less echogenic than the surrounding parenchyma. Distal pancreatectomy and splenectomy were performed with a suspected diagnosis of mucinous cystic tumor. The patient has had an uneventful postoperative period, and the pathologic finding was a lymphoepithelial cyst of the pancreas. Lymphoepithelial cyst of the pancreas is an unusual and benign entity that must be taken into consideration when evaluating a cystic lesion of the pancreas because a different therapeutic approach may be required.

In Brazil, the incidence of IPF due to alcohol-induced CP seems to be higher than in other countries. The authors analysed some general, epidemiologic, laboratory and radiologic features in 98 patients with CP, all of them alcoholics, divided in two groups: 49 patients without IPF (I) and 49 patients with IPF (II). The authors first analysed the following parameters in each group and then comparatively in both groups: age, sex, race, smokers and daily consumption of cigarettes, daily consumption of alcoholic beverages, years of alcohol consumption, and mortality. The authors concluded that pancreatic fistula plays in effusions the main role, secondary to cysts disruption or necrosis of the main pancreatic duct.
