Direct central vein puncture for silicone rubber catheter insertion. An alternative technique for Broviac catheter placement.

The indications for placement of the Broviac catheter have been expanded. Although cephalic vein cutdown has become the accepted technique for placement of the catheter, cannulation of this vein is not always possible. A technique is described for direct placement of the Broviac catheter into the subclavian or internal jugular vein. Formal venous cutdown is not required, and the technique does not sacrifice a vein. We have performed 21 consecutive catheter insertions in 20 patients without complications. It is a safe alternative method for silicone rubber catheter placement.

Expanded applications of Broviac catheter.

Sixteen Broviac catheters were inserted in 15 patients ranging from 15 to 61 years of age for purposes other than parenteral nutrition. These patients required long-term intravenous (IV) antibiotic therapy for cystic fibrosis or chemotherapy for malignant neoplasm. There were no major complications. The Broviac catheter provides excellent long-term IV access for total parenteral nutrition. In addition, it may be used very effectively in patients requiring extended IV antibiotic therapy and/or chemotherapy.

Gastrostomy without laparotomy: a percutaneous endoscopic technique.

A new technique has been developed to establish a tube feeding gastrostomy without a laparotomy. The procedure is particularly useful in high risk patients because general anesthesia is not usually required. The procedure is simple, safe, and rapid. It has been employed in 12 children (and 19 adults) with minimal morbidity and no mortality.

Percutaneous endoscopic gastrostomy: indications, limitations, techniques, and results.

Percutaneous endoscopic gastrostomy was introduced in 1980 as an alternative to traditional operative methods for the creation of a feeding gastrostomy. The indications for the procedure are essentially the same as those for traditional gastrostomy and include the inability to swallow secondary to neurological impairment, oropharyngeal neoplasms, and facial trauma. The method is contraindicated in the presence of massive ascites, total esophageal obstruction, coagulation disorders, and sepsis. Several variations on the original technique have been developed, and results with each are comparable. The morbidity and mortality with percutaneous methods has been at least as good as those reported for operative techniques while the cost has been lower and patient acceptance high. In spite of the ease with which gastrostomy may be performed by the percutaneous method, patient selection must be appropriate and details of technique closely followed if results are to remain acceptable.

Comparison of computed tomography and ultrasound in the evaluation of abdominal neuroblastoma.

A retrospective review of 15 cases of abdominal neuroblastoma was undertaken to determine the efficacy of ultrasound (US) in the evaluation of this disorder. Thirteen of the 15 cases were studied with both US and computed tomography (CT). It was found that US was accurate in all but two cases, where shadowing from bowel gas and dense tumor calcifications prevented accurate delineation of residual tumors. The CT scans were degraded by artifacts from surgical clips in three cases and by patient motion in one. A nonopacified loop of bowel was mistaken for tumor by CT in one case. We conclude that although both CT and US should be done initially, US alone is adequate in most cases for follow-up of abdominal neuroblastoma. When excessive bowel gas is encountered, or dense tumor calcifications are known to be present, CT is the modality of choice.
