[Gastric intramural pseudocyst in a heterotopic pancreas causing gastric outlet obstruction. Report of one case]. / Pseudoquiste pancreático intramural gástrico en páncreas heterotópico, una causa infrecuente de retención gástrica. Caso clínico.

Heterotopic pancreas is a silent gastrointestinal malformation that may become clinically evident when complicated by inflammation and pseudocyst formation. We report a 26 year-old male presenting with vomiting, pain and abdominal distention. An abdominal CT scan showed an important gastric distention secondary to a 4-cm cystic lesion located in the antrum wall. An endosonography showed that the lesion obstructed the gastric outlet and was compatible with a pseudocyst. A cysto-gastrostomy was performed draining the cyst. Its high lipase and amylase content confirmed that it was a pancreatic pseudocyst. Six months later, the lesion appeared again and a subtotal gastrectomy was performed Histopathology confirmed ectopic pancreatic tissue.

Multiple synchronous adenocarcinomas of the small bowel in a young patient: A case report.

INTRODUCTION: Adenocarcinoma of the small bowel is a rare neoplasm presented usually in elder patients as a single tumor. Its presentation as multiple tumors and in young patients is exceptional and there aren't any guidelines to orient its therapy. PRESENTATION OF CASE: We present the rare case of a sixteen-year-old woman that presents to the emergency department with an intussusception due to a small bowel tumor. The resected specimen showed multiple adenocarcinomas. A complete endoscopic and PET-CT study showed other 5 lesions from the duodenum to the ileum that were resected. Genetic counseling showed no pathogenic changes. The final staging was T2N0M0 and only surveillance was indicated. The patient is now 3 years without any recurrence. DISCUSSION: Multiple adenocarcinomas of the small bowel are a very infrequent presentation of the disease. Most common risk factors include Crohn disease and adenomas. Its presentation is usually vague with a delay in its diagnosis. The treatment remains mainly surgical with limited use of adjuvant therapy. The most important prognostic factor is lymph node involvement with 5-year survival that can range from 3%-60% depending on the stage. CONCLUSION: This case represents an exceptional presentation of a very rare pathology with few cases described in the literature. There isn't one single best study to stage the patient and surgery is still the standard of treatment while adjuvant therapies studies are being conducted. The young age and lack of predisposing factors or mutations leaves an open field for investigation.

Hemorroides: algunos conceptos fisiopatológicos clínicos y terapéuticos / Hemorrhoids: some physiopathological, clinical and therapeutical concepts

Se presenta una revisión de la aptología hemorroidaria destacando los eventos fisiopatológicos y las técnicas de manejo en las distintas modalidades actualmente empleadas. Se destaca el manejo quirúrgico usado por los autores y se exhiben los resultados obtenidos durante los últimos 3 años con una csuística de 110 pacientes. Estos resultados coinciden con lo expuesto en la literatura extranjera. Se concluye que el tema, pese a su alta incidencia, es de escaso conocimiento entre los médicos generales y los no especialistas y merece una mayor dedicación para comprender más a fondo los problemas planteados y poder ofrecer la mejor terapia a cada paciente en particular

Urgencias proctológicas / Proctological emergencies

Las urgencias proctológicas son frecuentes aunque no graves en la mayoría de los casos con excepción de las traumáticas. Su caracter de urgencia deriva fundamentalmente del dolor anorrectal que las caracteriza y que habitualmente es intenso. Se analizan las principales urgencias proctológicas, sin considerar las traumáticas, señalando las medidas terapéuticas médicas que completan el tratamiento quirúrgico, necesario en la mayoría de los casos
