Doppler-guided hemorrhoidal artery ligation with hemorrhoidopexy: source and prevention of postoperative pain.

Background: Transanal hemorrhoidal dearterialization, although it showed reliability, has not completely removed the issue of postoperative pain.

Objective: We investigated the causes of postoperative pain and proposed some changes of the technique in order to eliminate it.

Patients: One hundred six out of 188 operated patients were considered.

[Long-term cyclic and periodic omeprazole in the prevention of recurrences of duodenal ulcer].

The aim of this study was to establish if the discontinuous assumption of omeprazole was effective to reduce the recurrence of duodenal ulcer disease as the cyclic periodical assumptions of the same drug. Consequently two different posologies, after duodenal ulcer recovery, were compared, both based on omeprazole. In the first trial 20 mg/die were administrated for the first 15 days of every month, for 1 year.
