[Radical surgical treatment of a new neuroendocrine tumor of the ileocecal valve with liver metastasis and carcinoid syndrome].

Background: Neuroendocrine tumors are rare neoplasms which have a slow growth pattern. When liver metastases are diagnosed, treatment is controversial and it is focused in symptomatic control.

Aim: To present a patient with a neuroendocrine tumor that arised from the ileocecal valve and it was diagnosed with carcinoid syndrome and treated with radical liver and colonic resection.

Intraoperative US-guided large volume ethanol injection for hepatocellular carcinoma greater than 4 cm.

Background: Percutaneous ethanol injection has been successfully used for hepatocellular carcinomas (HCC) smaller than 5 cm in size. For larger lesions large volume ethanol injection has not been well explored.

Aim: Evaluate the results of intraoperative Ultrasonographic-guided large volume ethanol injection for HCC larger than 4 cm in size.

Hepatocellular carcinoma and hepatitis C in Mexico.

Background/aims: Hepatocellular carcinoma (HCC) has increased in many countries as a result of an increased frequency of hepatitis C virus (HCV) infection. In Mexico, the association of HCC to HCV infection has not been evaluated. This study aims to evaluate the epidemiological factors related to HCC in Mexican patients as well as the results of treatment.

Hepatocellular carcinoma in the youth. A comparative analysis with hepatocellular carcinoma in adulthood.

Background/aims: Hepatocellular carcinoma (HCC) is a very rare disease among young individuals. Epidemiological, clinical and histopathological features of this malignancy in the youth have not been thoroughly studied.

Methodology: A review of the clinical files of patients with HCC younger than 40 years of age, who were treated between May 1990 and July 2002, was performed.

[Laparoscopic liver surgery].

Introduction: Laparoscopic surgery has been widely used for digestive tract diseases, specially for gallbladder pathology. Laparoscopic liver surgery pretends to accomplish the same objectives of open surgery but with the advantages of minimally invasive surgery.

Aims: To evaluate the indications and recent results of laparoscopic liver surgery, as well as the technique.

[Neuroendocrine gastric carcinoma. A case report and review of current management].

Neuroendocrine or carcinoid tumors of the gastrointestinal tract considered previously extremely rare, are diagnosed at present with increased frequency due to the better capacity to identify neuroendocrine system cells in normal and pathologic conditions. Occasionally, these tumors secrete a great variety of vasoactive substances, producing the carcinoid syndrome. Gastric carcinoids are classified, according to their degree of differentiation into well differentiated and poorly differentiated tumors, also called neuroendocrine carcinomas.

[Arterial hypertension as clinical manifestation of non-parasitic hepatic cyst. A case report].

We present the case of a 32-year-old female patient referred to the Instituto Nacional de Cancerología (INCan) with a history of several months of systemic hypertension and epigastric pain associated to early postprandial satiety, fatigue, and dyspnea. At physical examination, a smooth, non-tender, palpable mass was found in right upper quadrant 7 cm below costal margin. Computed tomography (CT) scan showed right-sided non-parasitic liver cyst.

[Hepatocellular carcinoma in youth: a comparative analysis with hepatocarcinoma in adults].

Introduction: Hepatocellular carcinoma (HCC) is a very rare disease among young individuals. Epidemiological, clinical, and histopathological features of this malignancy in youth have not been thoroughly studied.

Patients And Methods: A review of clinical files of patients with HCC < 40 years of age treated between May 1990 and July 2002 was performed.

[Cavernous hemangioma of the liver and hepatic hemangiomatosis. Indications and results of the surgical resection].

Introduction: Cavernous hemangioma is the most frequent focal liver lesion. It affects mainly women and may cause symptoms such as abdominal pain, mass, and early satiety, or complications such as heart failure or coagulopathy. There are several options for treatment in symptomatic patients.

[Epidemiologic factors and results of treatment in peripheral and peri-hilar cholangiocarcinoma].

Objective: Cholangiocarcinoma is a rare malignant tumor that may occur anywhere along intra or extrahepatic biliary tree. Prognosis remains poor with overall 5-year survival rate of 5%. Experience in management of this lesion in Mexico is scarce.
