Botulinum toxin in the treatment of chronic urinary retention in women.

Six women were identified as having difficulty in voiding or complete urinary retention due to abnormal myotonic-like electromyographic (EMG) activity in the striated muscle of the urethral sphincter. An attempt was made to improve voiding by injection of botulinum toxin into the striated sphincter muscle. Although 3 patients then developed transient stress incontinence, demonstrating that sufficient botulinum toxin had been given to cause sphincter weakness, no patient had significant symptomatic benefit.

Endoscopic sphincterotomy: the whole truth.

An 8 year experience of 602 patients (median age 76 years) referred for endoscopic management of common bile stones is reported. No patient referred for treatment has been excluded. A diagnostic cholangiogram was achieved in 94 per cent and sphincterotomy was accomplished in 91.5 per cent. The bile ducts were demonstrated to be completely cleared of stones in 491 (81.6 per cent) of 602 patients. A mean number of 1.9 endoscopic retrograde cholangiopancreatography examinations per patient were necessary to achieve this result. Complications of endoscopic sphincterotomy, which were strictly defined, occurred in 10.5 per cent of patients although five patients had two complications (total complication rate 11.3 per cent). The 30-day mortality rate was 2.2 per cent, seven of 13 deaths (1.2 per cent) occurring as a direct result of sphincterotomy. There have been statistically significant improvements in bile duct clearance and complication rates with increasing experience of endoscopists.

Mammillary fistula.

During a 6-year period 38 patients with 52 mammillary fistulae were seen. On average, 5 abscesses had preceded recognition of a fistula in the areolar region (range 1-18). In 11 cases the fistulae were immediately apparent as discharging openings but they more commonly presented as subareolar abscesses. Fistulae were treated either by laying open or by excision of the track and at mean follow-up of 25 months (range 1-75) there has been recurrent fistula formation in only one case. Mammillary fistulae should be suspected and sought in all patients presenting with abscesses adjacent to the nipple.
