Recurrent massive haemorrhage from an endoscopically inevident isolated rectal varix.

Anorectal varices are identified endoscopically in up to 40% of patients with liver cirrhosis [Misra SP, Dwivedi M, Misra V. Prevalence and factors influencing haemorrhoids, anorectal varices, and colopathy in patients with portal hypertension. Endoscopy 1996;28:340-5] but are an infrequent cause of bleeding and their management remains controversial. We present a patient with chronic hepatitis C virus infection who developed recurrent haemorrhage from an isolated, endoscopically inevident rectal varix in the absence of clinical or endoscopic evidence of portal hypertension. The difficulties in diagnosis and management of anorectal varices are highlighted.

Stripping of failing haemodialysis catheters using the Ampltaz gooseneck snare.

The development of a fibrin sheath at the tip of a long-term haemodialysis catheter may lead to deteriorating blood flow rates, resulting in inadequate haemodialysis. Restoration of functional patency has been described using the technique of percutaneous fibrin sheath stripping (PFSS) using a wire snare device. Our purpose was to assess this technique within an established renal vascular access service. All catheters referred for the assessment of low blood flow rates on dialysis were considered for the procedure. Initial fluoroscopic assessment of the catheter was followed by stripping of the tip of the catheter using a gooseneck snare. Seventeen of 22 well-positioned catheters undergoing a single PFSS attempt were restored to function with a median prolongation of patency of 4.25 months. Two catheters underwent a second PFSS procedure providing additional patency. Nineteen of a total of 24 (79%) PFSS procedures successfully restored catheter function. Seven catheters with poorly positioned tips or a kink were not restored to functional patency using PFSS. Two patients developed a puncture site haematoma. No patient developed symptoms of pulmonary emoblism. In conclusion, PFSS restored function in 79% of attempts in well positioned catheters. The method is technically straightforward, with a low complication rate and has become a routine part of the renal vascular access service.

Computerised tomography guided lumbar sympathectomy.

Fifteen patients had lumbar sympathetic block using needle localisation by computerised tomography. The technique has the advantage that the needle route to the sympathetic plexus can be accurately planned, avoiding damage to other organs. In this study, 13 patients out of 15 had significant benefit from the procedure.

Computed tomography in deep-seated peripheral neurofibromas.

Seven peripheral deep-seated neurofibromas in five patients were examined by computed tomography (CT). This proved to be the most helpful investigation for demonstrating the precise size, shape and localisation of the lesion prior to surgery. In some cases CT may suggest the correct diagnosis where this has not previously been considered.

Oesophageal involvement in benign mucous membrane pemphigoid.

Benign mucous membrane pemphigoid is a relatively rare disease characterised by the presence of bullous lesions and erosions of the mucous membranes leading to scarring. Oral and conjunctival mucosae are most frequently affected. Occasionally, the oesophagus is involved and two radiological patterns, webs and smooth strictures, are seen.
