[Gastric necrosis following gastroplasty].

Introduction: Over the past ten years, laparoscopic surgery in the treatment of morbid obesity has expanded. However, there are few publications describing its side effects, notably the occurrence of gastric necrosis.

Observation: Two years after laparoscopic-banding for morbid obesity, a case of acute gastroenteritis in a 45 Year-old woman proved to be a gastric necrosis.

[Radiofrequency ablation of hepatocellular carcinoma in patients with cirrhosis].

Unlabelled: Radiofrequency is an effective therapeutic modality for patients with hepatocellular carcinoma. However few data are available with regard to the complication rate, the feasibility and long term survival.

Aims: To assess the response rate and complications of radiofrequency in cirrhotic patients with hepatocellular carcinoma.

[Complicated polycystic liver disease with intracystic hemorrhage and obstructive jaundice].

Polycystic liver disease, which is generally part of the autosomal dominant polycystic kidney disease, is often asymptomatic. We report a case of obstructive jaundice caused by compression of the biliary tract by a large haemorrhagic liver cyst. The patient was a man with sporadic polycystic liver disease without polycystic kidney disease and with normal renal function for his age.

Origin and initial course of the renal arteries: a radiological study.

The aim of this study was to determine the topography of the origin, implantation angle and initial course of the renal arteries in the transverse and frontal planes, from a prospective analysis of angiograms and helical CT-scans of 40 patients. In the frontal plane, the implantation angles of the right and left renal arteries were 73.8 +/- 17 degrees and 65.

[Solid pleural-based mass as initial manifestation of non-Hodgkin's lymphoma].

Subpleural involvement is a well-known site of advanced or recurrent lymphoma. But, to our knowledge, it has never been described as an initial manifestation of this disease. We report the case of a patient with solid subpleural mass revealing a non-Hodgkin's lymphoma.

Spiral CT quantification of aorto-renal calcification and its use in the detection of atheromatous renal artery stenosis: A study in 42 patients.

Purpose: To investigate whether a correlation exists between aortic and renal arterial calcifications detected with spiral CT and significant angiographic renal artery stenosis (RAS).

Methods: Forty-two patients (mean age 67 years, range 37-84 years), of whom 24 were hypertensive, prospectively underwent abdominal helical CT and aortic and renal arteriography. The 3-mm thickness CT scans (pitch = 1) were reconstructed each millimeter.
