OBJECTIVE: To assess the usefulness of covered, self-expanding metallic stents for alleviating stricture associated with malignant esophageal lesions. PATIENTS AND METHODS: Self-expanding metallic stents were placed in 10 patients with dysphagia related to stricture caused by malignant esophageal lesions. The stents were placed fluoroscopically with local anesthesia, and patency of the esophageal lumen was assessed by barium study after the procedure. The patients were then followed clinically. RESULTS: In all 10 cases patency of the lumen was renewed after stent placement. After the procedure 9 of the patients could tolerate a normal or near-normal diet; in the other patient esophageal perforation occurred, and clinical deterioration prevented oral intake of food. In one patient, 2 stents were needed because of the length of the stricture. Two patients experienced reflux after placement of the stent across the gastro-esophageal junction. Another patient had asymptomatic aspiration after stent placement in the proximal esophagus. In 2 patients, symptoms associated with tracheoesophageal fistula were relieved after placement of the stents. Six of the 10 patients died; mean survival after the procedure was 12 (range 1 to 56) weeks. The other 4 patients were alive at the time of writing, having survived for a mean of 7.5 (range 2 to 13) weeks; all of these patients tolerated a near-normal diet. CONCLUSIONS: The placement of covered, self-expanding metallic stents is a quick, effective method of palliating dysphagia related to stricture caused by malignant esophageal lesions.

Computed tomography appearance of malignant schwannoma of the liver.

Malignant schwannoma of the liver without associated neurofibromatosis is rare. The authors present one such case in a 35-year-old woman. Computed tomography demonstrated large liver masses with contiguous involvement of adjacent stomach tissue, consistent with local invasion.

Interventional radiology. Application to family practice.

New minimally invasive interventional radiologic procedures are being developed and refined. These alternatives to standard surgical treatments have fewer complications, shorter hospital stays, and lower costs. A variety of procedures that assist in both benign and malignant diseases are particularly suited for palliative care in end-stage malignancy.

Combined computed tomography and dacryocystography for complex lacrimal problems.

Two imaging modalities, computed tomography (CT) and dacryocystography (DCG), were combined to demonstrate the relationships between the lacrimal system and the surrounding soft-tissue structures. In selected cases, such as those involving severe facial trauma, midfacial tumours, significant sinus disease, or previous lacrimal, nasal or sinus surgery, this imaging technique may be useful in better evaluating the anatomy of the lacrimal system and planning a surgical approach.

The true canalicular angle: a mathematical model.

A mathematical formula that allows for the computation of the true angle between the upper and lower canaliculi using dacryocystograms is described. It was used to determine the true canalicular angle in 33 patients. The mean calculated angle at the 1.0 mm distance was 57.2 degrees +/- 13.0 degrees, and at the 0.5 mm distance was 65.2 degrees +/- 16.2 degrees. The true calculated angle was highly correlated with the angle measured in the Waters view. There was no statistically significant correlation between the right and left sides in the same patient. There was no statistically significant difference between the canalicular angle in males and females, and there was no correlation between canalicular angle and patient's age. A clinical application of this model is discussed.

The parathyroid adenoma: an imaging/surgical perspective.

The clinical picture of hyperparathyroidism has changed since the implementation of routine serum calcium testing, resulting in more asymptomatic patients undergoing early surgical exploration. Although operative complications (e.g., recurrent laryngeal nerve paralysis, hypocalcemia, etc.) are not prevalent, the risk can be minimized by minimizing tissue dissection. For this reason, we feel that preoperative tumor localization is of great importance. We report our imaging results of parathyroid adenomas, utilizing ultrasonography, technetium-thallium subtraction scanning, digital subtraction angiography and magnetic resonance imaging. We also present an imaging protocol which, we have found, maximizes preoperative identification of these tumors.
