The most common location is the upper rectum, in contiguity with a lesion of the torus uterinus. As part of a preoperative assessment, it is essential to establish an accurate and exhaustive map of intestinal lesions so that the surgeon can plan his actions. Transvaginal sonography and MRI correctly analyse pelvic and rectal involvement. Given the frequency of multiple intestinal sites, particularly sigmoid and associated ileo-caecal lesions, water enema CT should be performed. The role of rectal endoscopic sonography is debated.

Nous rapportons la première observation d'hépatite aiguë probablement induite par la prise de ce médicament.

La localisation la plus fréquente est rectale haute, en contiguïté d’une atteinte du torus. Dans le cadre d’un bilan préopératoire, il est primordial d’établir une cartographie précise et exhaustive des lésions digestives afin que le chirurgien puisse programmer son geste. L’échographie endovaginale et l’IRM analysent correctement les atteintes pelviennes et rectales. Devant la fréquence des localisations digestives multiples, notamment sigmoïdiennes et iléocæcales associées, il convient de faire un coloscanner. La place de l’échoendoscopie rectale est discutée.

Surgery remains the only option for cure. Accurate diagnosis and staging are essential for appropriate management of patients with pancreatic cancer. This paper reviews the state of the art for imaging modalities in the diagnosis and staging of pancreatic adenocarcinoma. The crucial role of CT has increased with the new generation of multidetector CT.

Les causes d’épaississement focal ou diffus de la paroi vésiculaire sont multiples, parfois d’origine extrabiliaire et dominées par la pathologie bénigne et inflammatoire. L’exploration radiologique est dominée par l’échographie qui reste l’examen de première intention et est orientée avant tout par la clinique dont la prise en compte est un élément fondamental de l’attitude diagnostique. La TDM et l’IRM sont utiles en cas de pathologie maligne et dans les formes compliquées de pathologies inflammatoires. Cet article se propose de discuter et d’illustrer les principales lésions de la paroi vésiculaire.

Published data has noted a failure rate of 8% due to deployment, capture, and other technical problems. A new disposable device (Boston Scientific Corporation) with preassembled pistol grip handle function may facilitate operation. AIM: To prospectively evaluate the cost, technical performance, and procedure time of a disposable lithotripter. METHODS: 20 pts with common bile duct (CBD) stones were enrolled. Data included device costs, stone size, number of stones, CBD size and configuration (normal, sigmoid or stricture), ease and number of cannulations, basket function (deployment; deployed shape), stone capture and crushing success, procedure time, and complications. The Olympus device was used in failed cases. RESULTS: The disposable lithotripter cost 333perprocedureandthereusabledevice333 per procedure and the reusable device 333perprocedureandthereusabledevice625. Maximum stone size averaged 16.5• mm (range 10-30 ram). 16 pts had multiple stones (median 5, range 2-12). Mean CBD diameter was 20.5• mm (range 12-38 ram). CBD cannulation was successful in all within 5 attempts. Basket deployment failed in I pt due to stone size and was misshapen in 14. Stone capture, fragmentation, and clearance were ultimately successful in 16 pts (80%). 2 pts required 2 disposable lithotripters. CBD clearance was incomplete with the lithotripsy basket in 2 pts. Abnormal CBD configuration was noted in 2 out of 4 pts with failed capture and 7 out of 16 with successful clearance. No statistically significant difference between the CBD size, stone size, number of stones, and successful clearance was observed. Average procedure time was 90.5+9.6 rain (n~16) with the disposable l ithotripter and 105.3+21.2 (n--4) with the reusable device. One patient developed a delayed sphincterotomy bleed and in one case there was damage to the endoscope elevator. CONCLUSIONS: I. The success rate of stone capture and disruption with the disposable lithotripter (80%) was less than the published data with the Olympus device (96%). 2, Overall, the disposable device costs substantially less. 3. Basket deployment was less than ideal in most cases. 4. Failure of stone capture and disruption was often associated with abnormal CBD configuration. 5. Procedure times between the disposable and reusable lithotripter were comparable.
