The use of metallic stents in the treatment of malignant superior vena caval obstruction.

Superior vena caval obstruction due to malignancy is conventionally treated by radiotherapy and/or chemotherapy. In patients with unresolved or recurrent obstruction after treatment, expandable metallic stents can be percutaneously placed within the vena cava for relief of symptoms. In this series, metallic stents were successfully deployed in 11 consecutive patients with bronchial carcinoma. Gianturco Z stents were used in 10 patients and Strecker stents in one. There were 2 minor procedural complications of no sequelae. All patients had partial or full relief of symptoms after the procedure. On follow-up (mean 3.9 months), 9 patients had no recurrent symptoms up till the time of death or the present time. Two patients had recurrent obstruction, both within a week of the procedure. Based on our experience, percutaneous stenting was an effective means of palliation in this group of patients when other treatment modalities failed.

Angiographic demonstration of primary aorto-enteric fistula--a case report.

Primary aorto-enteric fistula is an uncommon but lethal disease. The key to patient survival is early diagnosis and treatment. Angiography may be diagnostic. However, angiographic documentation of this condition is rare as the patients are usually very ill when the decision for angiography is made. A case of primary aorto-enteric fistula with fatal haemorrhage is described with angiographic documentation. This is the first angiographically demonstrated case reported locally.

Defecating proctography: local experience.

Between October 1990 to November 1991, defecating proctography was performed on a select group of patients with complaints of persistent constipation or sensation of incomplete evacuation. Out of the 27 patients studied, a high percentage (88.8%) showed some form of anatomical or functional abnormality of the defecating mechanism. As defecating proctography is a relatively new mode of investigation locally, we briefly describe our method and results. These include rectocele formation, intrarectal mucosal prolapse, intussusception and pubo-rectalis paradox. Some of these cases may be amenable to surgical correction.
