Cataract surgery is the most frequent surgery performed in the world. Modernization of cataract surgery is a continuous process and recent technological progress have enlarged the spectrum of treatable refractive errors, improved safety of surgery, speed of visual recovery and reduction of complications rate. Thus, during the last years, refractive intraocular lenses such as toric and multifocal IOLS have been introduced in practice, as well as torsional phacoemulsification and corneal microincision. For endophthalmitis prophylaxis, modern management includes intracameral injection of antibiotics. The future of cataract surgery is probably to replace phacoemulsification surgery by laser surgery, which is safer and more reproducible.

More than the number of real novelties, trends and preliminary results characterise the annual development in surgery. The wealth and diversity of topics to be covered require arbitrary choices, therefore not necessarily complete. The constant development of choledocolithiasis management, dominated by minimal invasive technology, treatments of unusual nature of two frequent proctological conditions, fistulae and haemorrhoids, the increasing importance of metabolic bariatric surgery, as well as the strict rules of effective melanoma treatment, represent as many directions in which the operating procedure, although unseen, continue to gain quality and security.

1. Abstract Au XXème siècle la médecine a passablement évolué et la question de l'implication du patient dans le processus de décision thérapeutique devient petit à petit une nécessité. La théorie du consentement éclairé apparaît en Suisse à la fin des années 70 et l'information du patient devient un thème incontournable. C'est dans cette perspective que le formulaire de consentement vient progressivement s'imposer. Dans la première partie de ce travail, nous avons cherché à mettre en évidence qu'elles pouvaient être les directives éthiques et juridiques en matière de formulaire de consentement en vue d'une intervention chirurgicale. Pour que ce formulaire soit validé, il doit être accompagné d'une information claire et appropriée afin obtenir un consentement libre et éclairé du patient tant du point de vue éthique que juridique. Dans la deuxième partie, nous nous sommes intéressés à l'usage et l'utilisation du formulaire de consentement employé au sein du service de chirurgie pédiatrique au CHUV et à l'HEL. Afin d'en avoir un bon reflet, nous avons soumis un questionnaire à des chirurgiens cadres ou chefs de cliniques du service de chirurgie pédiatrique. Ce questionnaire se base sur des questions soulevées par la littérature traitant du sujet ainsi que sur l'article 21 de la loi sur la Santé publique du canton de Vaud qui dit, en résumé, que le minimum requis est le droit à l'information afin de donner valablement un consentement. Il est composé de trois parties. Dans la première partie, il en ressort qu'en règle générale les chirurgiens s'accordent sur la définition du formulaire de consentement. Ils sont dans l'ensemble satisfaits du formulaire en vigueur et n'en modifieraient pas la structure. Dans la deuxième partie, la signature du formulaire est vue comme une obligation mais la raison de cette obligation n'a pas la même signification pour chacun et les avis divergent quant il s'agit de savoir qui cela protège. Dans la troisième partie, ils s'accordent tous sur le contenu de l'information jugé nécessaire à donner aux parents des futurs opérés. En conclusion, les chirurgiens pédiatres semblent globalement satisfaits du formulaire actuel et peu le modifieraient. Nous trouvons important de mentionner que peu soulèvent le fait que le principal concerné par l'intervention est l'enfant et que son avis n'est pas toujours sollicité. A l'avenir, il sera important d'impliquer l'enfant dans cette démarche tout en tenant compte de son degré de maturité.

In patients undergoing non-cardiac surgery, cardiac events are the most common cause of perioperative morbidity and mortality. It is often difficult to choose adequate cardiologic examinations before surgery. This paper, inspired by the guidelines of the European and American societies of cardiology (ESC, AHA, ACC), discusses the place of standard ECG, echocardiography, treadmill or bicycle ergometer and pharmacological stress testing in preoperative evaluations. The role of coronary angiography and prophylactic revascularization will also be discussed. Finally, we provide a decision tree which will be helpful to both general practitioners and specialists.

For severe obesity (BMI > 35 kg/m2), bariatric surgery is not only the best, but often the only means of obtaining sufficient and durable weight loss. This article aims to review the available bariatric procedures. Gastric bypass remains the reference when it comes to the risk/benefit ratio. Gastric banding is declining rapidly due to the high prevalence of long-term complications. Primary malabsorptive procedures remain largely unpopular because of their potential nutritional complications. Sleeve gastrectomy, although it is not reversible as it includes a significant gastric resection, increases currently in popularity because of its apparent simplicity and the fact that early results regarding weight loss mimic those obtained with gastric bypass.

Is surgery for primary hyperparathyroidism easier when methylene blue (MB) is given preoperatively? This retrospective study compares the durations of interventions for primary hyperparathyroidism carried out after i.v. MB administration to those when no MB was given. Over a period of 20 years (June 1976 to December 1996), 175 consecutive patients (56 men and 119 women, with ages ranging from 16 to 92, mean 59.6) were operated upon for primary hyperparathyrodism; 55 were operated before February 1986--the period when BM was introduced routinely, and 120 after. Thirty-two other patients were excluded from the study: 14 had had a previous cervicotomy and 18 another procedure in addition to the parathyroidectomy (usually on the thyroid gland), two conditions which prolonged the time devoted to parathyroid identification and excision. Preoperative calcemia averaged 2.97 mmol/L (2.34 to 4.59) and mean preoperative PTH was equal to 2.6 times the upper normal limit (0.5 to 24.1). Both groups were similar for as age, sex, preoperative calcium and PTH, and histologies. Methylene blue was administered intravenously (5 mg/kg diluted in 500 cc of 5% glucose) over a period of time of one hour starting two hours prior to surgery. All 175 procedures were performed by two surgeons and duration of surgery was recorded from the anesthesiologist's notes. There were 149 adenomas (85%), 24 hyperplasias (14%), a combination of both in two, and unspecified in two others. Except for a case of acute lower back pain synchronous to the injection of the dye (which was immediately stopped), MB was well tolerated. Mean duration for the 55 interventions performed without MB was 68 minutes (35 to 140, median 60), compared to 49 minutes for the 120 procedures carried out after MB had been given (20 to 155, median 45). Differences in operative, times were highly significant (p < 10(-6) and represented a gain of time of 27%. Surgery for primary hyperparathyroidism was significantly shorter when it was preceded by the administration of MB, a dye which facilitates the identification of pathologic parathyroid gland(s).
