[Role of magnetic resonance imaging in preoperative assessement of hilar cholangiocarcinoma].

Magnetic resonance cholangiopancreatography is a non-invasive imaging, highly performant in detecting and locating biliary stenosis and in predicting its malignancy. The combination of two and three-dimensional MRI sequences is recommended to assess a biliary obstacle. Cholangiopathies are the main differential diagnosis of cholangiocarcinomas.

Hydatid Cyst of the Spleen: Tunisian Series of 21 Cases.

Hydatid disease is a parasitic infection caused by Echinococcus granulosus. Splenic involvement is rare even in endemic areas. The aim of this study is to specify epidemiologic features, diagnostic tools, and therapeutic modalities of this uncommon entity.

[Surgical complications of colostomies].

Background: The colostomy may be terminal or lateral, temporary or permanent. It may have psychological, medical or surgical complications.

Aim: reporting the incidence of surgical complications of colostomies, their therapeutic management and trying to identify risk factors for their occurrence.

[The lithiasic acute cholecystitis: laparoscopic treatment (About 106 cases)].

Aim: To assess the feasibility and the advantages of the coelioscopy in the treatment of the acute cholecystitis.

Methods: From January 1996 to December 2001, 106 laparoscopic cholecystectomies for acute cholecystitis have been collected. The diagnosis of acute cholecystitis has been confirmed for all cases by the pathologic exam.

Spontaneous rupture of hepatocellular carcinoma in children.

Spontaneous rupture of hepatocellular carcinoma (HCC) with intraperitoneal haemorrhage is a life-threatening complication with a high mortality rate. The mechanism of spontaneous rupture of HCC is unknown. It may be related to venous congestion, haemorrhage, central necrosis, or trauma.

Complicated jejunal diverticulosis: A case report with literature review.

Context: Jejunal diverticuli are rare and usually asymptomatic. More commonly, they are seen as incidental findings on CT images, enteroclysis, or during surgery. Complications such as bleeding, perforation, obstruction, malabsorption, diverticulitis, blind loop syndrome, volvulus, and intussusceptions may warrant surgical intervention.

Emphysematous cystitis of the diabetic patient.

Background: Emphysematous cystitis is defined by the presence of gas in the urinary bladder wall. It complicates urinary tract infections especially in diabetic patients.

Aims: We present a case of emphysematous cystitis in a diabetic patient with a poor glycemia control and we discuss diagnostics and treatment items of this uncommon and serious infection.

[Breast cancer in men].

Breast cancer in men is rare and most often occurs at or after the age of 60 years. Prognosis is poor when it is discovered at a late stage, as it often is in men, although it should be easier to detect because men have so little breast tissue. The causal mechanism appears to depend on hormone metabolism abnormalities related to elevated estrogen or prolactin levels.
