[Clinical and biological study of the 31 cases of gallstones].

This study reports the clinical and biological signs, as well as the morphological aspect and the chemical composition of the calculus during the biliary stones. The study population consisted of 31 patients with an average age of 49 years (30 women and one man) with biliary lithiasis and who had cholecystectomy. Hepatic colic and epigastralgia were the most evocative clinical signs.

What remains to surgeons in the management of abdominal tuberculosis? A 10 years experience in an endemic area.

Background: Tuberculosis (TB) is a common endemic disease in Tunisia. Abdominal location is rare. Early diagnosis of abdominal TB remains difficult due to its non-specific clinical presentations.

Detection of a new JCV strain of genotype A in a subpopulation of colorectal adenocarcinomas in Tunisia.

The etiology of colorectal cancer (CRC) remains elusive in spite of major advances in knowledge of this disease and related risk factors. Several studies report the detection of human polyomavirus JC (JCV) in colorectal tumors and some suggest its association with CRC. Since many known human virus associations with cancer are linked to factors such as ethnic and geographical origin, it is interesting to search for the postulated association of JCV with CRC in different populations and regions.

[Spigelian hernias].

Spigelian hernias represent 1-2% of all abdominal wall hernias. The pathogenesis often involves a dehiscence of the transverse and internal oblique muscle aponeurosis. The diagnosis is made by physical examination; but sometimes it is complicated by obesity.

Primary hydatid cyst of the gallbladder: an unusual localization diagnosed by magnetic resonance imaging (MRI).

Hydatid disease is endemic in Tunisia and has been considered as one of the most common surgical pathology. Several localizations have been described, but hydatidosis of the liver is the most frequent clinical entity. Primary hydatid cyst of the gallbladder is very rare.

[Effectiveness of intravenous magnesium on postoperative pain after abdominal surgery versus placebo: double blind randomized controlled trial].

Purpose: the purpose of our trial is to evaluate the impact of the intravenous perfusion of magnesium on the morphin consumption and on the controle of the stress neuro-endocrin and metabolic reaction in major digestive surgery.

Methods: prospective, randomized, double blinded study versus placebo.Including 42 ASA I patients, scheduled for major digestive surgery, randomized into two groups : Magnesium, receiving a bolus of magnesium sulfate; 50 mg/kg, followed by a continuous perfusion; 10 mg/kg/h for the 24 postoperative hours.

[Feasibility of laparoscopic treatment of duodenal ulcers: results of 160 cases].

Aim: The objective of this study is to evaluate the feasibility, efficacy and safety of laparoscopic repair for perforated duodenal ulcer.

Methods: One hundred and sixty patients were treated by coelioscopic procedure for a perforated duodenal ulcer. The procedure consists on a suture of perforated ulcer associated with a peritoneal lavage.

[Common bile duct distomatosis managed by coelioscopic aproach. One case report].

Biliary distomatosis is caused by a parasitis of trematode family: the fascialo hepatica. It is a rare affection in Tunisia. The diagnostic is often done in the status phase.

[Filiation hamartoma polyposis dysplasia and small bowel adenocarcinoma].

Peutz-Jeghers syndrome is a hereditary affection with dominant autosomal transmission. The risk of cancerisation is largely higher than that in the general population. Dysplasia is rare.
