[Thyroid surgery applicable in developing countries]. / Chirurgie de la thyroïde applicable dans les pays en développement.

Thyroid surgery in developing countries is performed by general surgeons with limited diagnostic and therapeutic resources. The aim of this review is to describe the indications for and appropriate type of surgery according to the diseases observed. Endemic goiter (grade 1 and 2) usually regresses with iodine therapy. Surgery is indicated only for its complications: mechanical, neoplastic, or related to hyperthyroidism. The choice of operation depends on the specific disease and also on the likelihood that thyroxine will be continuously available for the patient's lifetime. Total thyroidectomy should be avoided whenever possible if thyroxine supplies are unreliable. Hemithyroidectomy and subtotal thyroidectomy are the techniques that should be used in priority.

Fortuitous discovery of common bile duct stones: results of a conservative strategy.

OBJECTIVE: The incidence of fortuitously discovered stones in the common bile duct is about 5%. The purpose of this study was to determine the rate of spontaneous clearance of asymptomatic stones in the common bile duct discovered fortuitously during cholecystectomy. PATIENTS AND METHODS: Intraoperative cholangiography was performed in all patients undergoing cholecystectomy for symptomatic gallbladder stones. If a filling defect of the common bile duct was discovered, a transcystic drain was inserted. Surgical or endoscopic extraction was not proposed initially. A control cholangiogram was performed on the second postoperative day then during the sixth postoperative week. If a stone persisted at the sixth week, endoscopic extraction was undertaken. RESULTS: Cholecystectomy was performed in 124 patients with symptomatic gallstones and no signs predictive of stones in the common bile duct. A stone was found fortuitously in the common bile duct in 12 patients. The control cholangiogram was normal in two of these patients on day two (16.7%) and in six others (50%) at the six-week control. All 12 patients remained free of symptoms suggesting the presence of a stone in the common duct. Presence of the drain had no impact on quality-of-life. Endoscopic extraction was finally performed for four patients (33.3%) to remove a stone from the common bile duct. CONCLUSION: Early surgical or endoscopic extraction of stones in the common bile duct should not be undertaken systematically in asymptomatic patients. Spontaneous asymptomatic clearance of the common bile duct is observed in about half of patients.

[Ruptured mesenteric aneurysm from Listeria monocytogenes]. / Rupture d'un anévrisme infectieux à Listeria monocytogenes de l'artère mésentérique inférieure.

Infections due to Listeria monocytogenes usually occur in pregnant women, in elderly or immunocompromised patients. We report the case of an immunosuppressed woman who had been hospitalized for a meningoencephalitis due to L. monocytogenes. She was operated on for an abdominal hemorrhagic shock due to a ruptured mycotic aneurysm of the inferior mesenteric artery. Arterial aneurysms due to this germ are rare and occur on large arteries. Only 17 cases have been previously described in the literature and just one concerning a mesenteric artery.
