[Recurrences of adenomas of the large intestine].

A retrospective mathematic-statistical evaluation of cases of adenoma of the large intestine--asymptomatic (group 1) or bleeding one (group 2)--showed the frequency and pattern of recurrence and malignant transformation following electrocoagulation to be identical in both groups. Such change in the histologic type as transformation of tubular polyps to a villous pattern proved to be an important factor of risk for relapse and neoplastic growth of solitary adenoma of the large intestine. Villous adenoma showed the highest rate of recurrence and malignant transformation. It is considered to be obligatory precancer.

Treatment of haemorrhoids at the Moscow Research Institute of Proctology.

The article sums up experience acquired with the treatment of more than 4,000 patients with haemorrhoids at the Research Institute of Proctology (Moscow). The pattern that emerges is that only about 30% of patients with haemorrhoids should be subjected to radical haemorrhoidectomy. Others can be cured on conservative lines, including sclerosing injections. Two modifications of haemorrhoidectomy are described which have been developed at the Research Institute of Proctology (Moscow). Long-term results of haemorrhoidectomy have been examined in nearly 1,500 patients. In the post-operative period of five and more years, 3.78% of patients had recurrences.
