[Lesions caused by the ingestion of caustics].

The diagnostic and therapeutic approach to the maiagement of lesions caused by ingestion of caustic substances has made substantial progress in the past few years and has now been codified. The linch-pins of the present approach are emergency endoscopy for an immediate assessment of the lesions and total parenteral nutrition to reduce the morbidity in patients whose lesions may be expected to take a long time to heal or may require surgical repair. The diagnostic and therapeutic protocol advocated derives from a close examination of the literature and from personal experience.

[Recent traumatic rupture of the diaphragm in patients with multiple injuries].

The authors report on 16 cases of recent traumatic diaphragmatic lesions in polytraumatized patients referred to them over the period 1979-86. After examining the diagnostic problems relating to this type of lesion, the authors describe the anatomico-topographical, clinical and therapeutic aspects. They conclude by stressing the need to explore the diaphragmatic cupulae systematically in the course of surgery for blunt abdominal trauma.

[Traumatic chylothorax (apropos of a case following a closed vertebral-thoracic injury)].

The authors report a case of chylothorax due to blunt trauma with fracture of the spine in a man aged 60. After mentioning the possible pathogenesis and clinics of the case shown, the Authors explain the treatment successfully adopted, that is, the ligature of thorax duct at his inlet in the thorax through right thoracotomy on the 5th intercostal space.

Does iodine concentration affect the diagnostic efficacy of biphasic spiral CT in patients with hepatocellular carcinoma?

BACKGROUND: We investigated the effect of iodinated contrast medium concentration on increased neoplastic lesion enhancement and its direct relation to diagnostic efficacy in biphasic spiral computed tomography for detection of hepatocellular carcinoma. METHODS: A pilot, single-center, randomized, double-blind, crossover, comparative study was performed and included 22 participants. Each patient underwent two separate biphasic contrast-enhanced spiral computed tomographic examinations. Scans were performed with iomeprol containing 400 (iomeprol 400) or 300 (iomeprol 300) mg of iodine per milliliter (Iomeron, Bracco Imaging SpA, Milan, Italy) with a 2- to 12-day window scan; patients were given an equal total dose of 45 g of iodine at a fixed injection rate of 4 mL/s. Comparison included assessment of quantitative and qualitative parameters. RESULTS: Lesion density and lesion-to-liver contrast increased more markedly with the higher concentration of contrast medium during the arterial phase (p = 0.0016 and 0.0005, respectively). There was no significant difference in any parameter between the two concentrations during the portal phase. Number of lesions detected during the arterial phase increased from 37 with iomeprol 300 to 42 with iomeprol 400; in the portal phase, the respective numbers were 34 and 36. CONCLUSION: Even though a small number of patients was examined, our study suggests that, in patients with cirrhosis, an increased concentration of iodine improves liver-to-lesion contrast and may improve the detection of hepatocellular carcinoma.

Carbon dioxide digital subtraction angiography in oncological-interventional radiology.

AIMS AND BACKGROUND: The aim of this work is to demonstrate the usefulness of carbon dioxide, used as contrast agent, in special indications in vascular interventional oncological procedures. METHODS: We studied 40 patients with digital subtraction angiography enhanced with CO2 as a contrast agent. At the same time we utilized also, in all cases, jodinated contrast agent to evaluate the different opacification gradient, the different viscosity range and the different perfusion. RESULTS: The low viscosity of CO2 allows demonstration of the presence of even minimal blood losses in gastrointestinal tumors and enhances arteriovenous shunts in hepatocellular carcinoma. Carbon dioxide can also be employed to assess the patency of small-sized catheters for chemotherapy infusion which do not allow easy injection of the traditional iodinated contrast agents characterized by high viscosity. CONCLUSION: Carboangiographic study combined to digital subtraction angiography can clear some diagnostic problems and is further method to assess the outcome of angiographic interventional procedures in oncology.

[Hemorrhages of the lower digestive tract: the diagnostic and therapeutic approach].

The authors describe their experience with colo-rectal haemorrhage. They stress the tendency towards spontaneous arrest of such haemorrhages (92.6% of cases) as the usefulness of emergency colonoscopy in diagnosing the cause and/or site of the haemorrhagic lesion (85.7% of positive results in the present series). Therapy may be conservative (endoscopic or in the course of angiography) or surgical. Surgery is indicated in cases failing to respond to conservative therapy and in cases of unarrestable haemorrhage and usually consists in segmental resection of the portion of the intestinal tract involved.

[Leiomyosarcoma of the Meckel's diverticulum (presentation of a new case)].

A new case of Meckel's leiomyosarcoma is described. The rarity of the disease, the problems of differential diagnosis and the difficulty of establishing the malignant nature of the condition and thus the prognosis justify the report together with a review of the most recent literature.

[Retroperitoneal leiomyosarcoma (case report)].

After a short introduction about the retroperitoneal tumors classification the Authors write on the management of this tumor. They present their case report: surgical treatment of retroperitoneal leiomyosarcoma. Actually the role of surgical strategy in the management of resectable retroperitoneal tumors is the most important than adjuvant therapy, even if the surgery must be very demolitive.
