Alvarado score in the diagnostic of pain in the right lower quadrant.

Background: Acute appendicitis neither suspected nor diagnosed could develop a perforation or otherwise it would take to removing of a normal appendix.

Objectives: Utilization of a clinical score system for aided diagnosis of this pathology and can reduce a negative appendicitis.

Setting: National Clinicas Hospital.

Useful of Tokyo guidelines in the diagnosis of acute cholecystitis. Anatomopathologie correlationship.

Background: In the year 2007 a group of experts come together to discuss criteria for acute cholecystitis and to establish therapeutic guidelines and states of gravity in this disease.

Objectives: we correlated the criteria of the Tokyo Guidelines 2007 with the anatomopathology study of the surgical specimen.

Setting: Service of Urgencies of the National Clinic Hospital in Córdoba, Argentine.

Primary hydatid cyst of the pancreas.

Hydatid cyst of the pancreas is a rare location of this disease. We study the case of a female patient with primary hydatid cyst of the pancreas coming from and endemic area and presenting pain and palpable tumor in epigastrium and right upper abdomen. The patient was studied with ultrasound scanning and CT scan in which it was interpreted as hydatid liver cyst.

[Mannheim index in acute perforated abdomen in patients 65 years].

We present a prospective and protocolizeted study of 98 patients over 65 years, underwent emergency surgery for perforated acute abdomen in the Hospital Nacional de Clínicas during the period from April/2007 to April/2013. The purpose was to determine the morbidity and mortality of this entity in the elderly. Mainly affected were women between 65 and 75 years.

[Retroperitoneal Tumor: Neurofibroma.].

The neurofibroma is a benign tumor that grows from the sheath of the peripheral nerves, which is often localized on superficial tissues, especially in isolated forms. The neurofibromas can be of two types, localized or diffuse, the last one closely related to Von Recklinghausen disease or NF-1. We described a 37 years old male e patient, 37 years without symptoms, and the computed tomography scan (CT), and magnetic resonance imaging showed a tumor in proximity to the right kidney, the psoas muscle, the spine and compressing the cava vein, but cannot be accurately determinate the invasion of these structures.

[Mini-laparoscopy vs. laparoscopy for the gallblader stone treatment. Prospective and comparative study].

Background: Laparoscopic cholecystectomy is considerated as the gold standard for the gallbaldder stones treatment, however, in the international literature the adapted smaller incisions is still an alternative procedure. Objetives: To compare the results of the laparoscopic cholecystectomy with the cholecystectomy by adapted smaller incisions.

Design: Prospective and comparative protocolized study.

[Right iliac fossa pain and Alvarado Score].

Introduction: Unsuspected or undiagnosed acute appendicitis could progress to a perforation or could lead to the removal of a normal appendix.

Objectives: using a clinical score system as a diagnostic tool for this pathology and can decrease negative appendectomies.

Material And Method: Prospective and protocolized study.

[Adenosquamous and squamous carcinoma of the gallbladder].

Introduction: Squamous and adenosquamous carcinomas of the gallbladder have poor prognosis. Because these tumors are silent in the initial stage, they are generally diagnosed in advanced stages.

Material And Method: We performed a retrospective observational study of five patients with squamous or adenosquamous carcinoma of the gallbladder.
