[Current status of carotid surgery].
Introduced in the fifties, reconstructive surgery of the carotid arteries has undergone an extensive development in Europe and the United States. Prospective randomized multicentric clinical trials have clearly demonstrated its effectiveness in stroke prevention for both symptomatic and asymptomatic patients with tight carotid stenosis. The diminution of relative risk secondary to surgery is at least 40%; it is 80% for major ipsilateral stroke. There is no benefit if the vessel narrowing is less than 30%. For the 30 to 70% stenosis a benefit has not yet been clearly established. The prophylactic effect of carotid surgery is highly dependent of a low postoperative morbidity. The 30 day stroke plus death rate should not exceed 3% for asymptomatic patients and 5% for symptomatic patients. Postoperative morbidity-mortality has greatly improved over the last twenty years. Several factors are involved; the main improvement may be related to better surgical technique assessed by intra-operative angiographic control rather than the many methods of monitoring or cerebral protection. Ten years patency of arterial reconstruction is greater than 90%. Stroke protection is effective since the annual rate of cerebral events in an operated population is about 2% while it is about 10% in a control population. Inversely, late mortality is still high, primarily due to cardiac disease.

[Kidney traumatism in general surgery (65 cases)].
From September 1989 to September 1994, 65 patients, 15 females and 50 males, with a mean age of 32 +/- 14 years were admitted in the emergency unit for renal trauma. In 38.5% of cases multiple trauma was present. Lesional mechanism was most frequently contusions (49.2%) and deceleration injuries (43.1%). Gross hematuria or microscopic hematuria were presents in 72.3% of cases. The sensibility of systematic abdominal echography was 100% in case of perirenal hematoma and 65% in case of parenchymatous lesions. Only 23 patients were operated (35.3%) because of low blood pressure. None secondary operation was necessary in abstention group. Global mortality was 7.7%. Postoperative morbidity was 20% and specific morbidity in abstention group was 10.7%.

Mechanically stapled esophagojejunostomy. Results of a prospective series of 176 cases.
BACKGROUND/AIMS: To evaluate the reliability of stapled esophagojejunostomy. MATERIAL AND METHODS: We studied a non-selected prospective series of 176 consecutive total gastrectomies (169 cancers, 7 benign pathologies). RESULTS: Hand-sewn esophagojejunostomy was performed 5 times after failure of the stapled esophagojejunostomy. There were fourteen hospital deaths (8%), and 63 patients (36%) presented complications. There were 5 anastomotic leaks (2.8%) but non were responsible for deaths. In these 5 cases, there had been an incident during construction of the esophagojejunostomy. Such an incident was the only significant risk factor for an anastomotic leak: 17% after an incident and 0% in the absence of an incident (p < 0.001). We observed no cases of anastomotic stricture. CONCLUSION: Stapled esophagojejunostomy is a reliable technique when technical precautions are taken. It is easier to reproduce than hand-sewn esophagojejunostomy and has demonstrated low specific morbidity and no direct mortality.
