Use of anorectal manometry during rectal infusion of saline to investigate sphincter function in incontinent patients.

Anal and rectal pressures and external sphincter electromyogram were recorded continuously during rectal infusion of 1.5 L saline in 18 normal subjects and 37 patients who complained of diarrhea and fecal incontinence. All subjects exhibited a pattern of regular fluctuations in anorectal pressure and electromyogram.

Rectal malignant lymphoma in chronic ulcerative colitis.

Carcinoma of the colon as a complication of ulcerative colitis is relatively common, whereas malignant lymphoma is apparently rare; there are approximately 20 recorded cases. We report a case of follicular lymphoma of the rectum in a 73 year old woman with a 21 year history of ulcerative colitis. In view of the possible immune basis of ulcerative colitis, it is important to report and accurately classify cases of lymphoma arising in association with it.

Treatment of infiltrating bladder carcinoma.

One hundred and seventy-five patients with invasive bladder tumours are reviewed. The overall crude survival rate was 30% at 3 years and 23% at 5 years. The 5-year survival rates for T2 and T3 tumours treated by radical radiotherapy were 38% and 28% respectively.
