Abstract
Objective: To establish whether eicosanoid production characterizes the inflammatory processes of the haemorrhoidal plexus. Design: Open, single patient group study. Setting: Private practice. Patients: Fourteen patients selected for haemorrhoidectomy. Interventions: Specimens were obtained during either the acute (five patients, group I) or chronic (nine patients, group II) phase of the disease. We assayed the concentrations of prostaglandins E2 (PGE2) and F2α (PGF2α) and of leukotriene B4 (LTB4) in the vascular and mucosal tissues of the anterior and posterior haemorrhoidal plexus. Results: Very high levels of prostaglandins were recorded (up to 1445
期刊介绍：
The leading scientific journal devoted entirely to venous disease, Phlebology is the official journal of several international societies devoted to the subject. It publishes the results of high quality studies and reviews on any factor that may influence the outcome of patients with venous disease. This journal provides authoritative information about all aspects of diseases of the veins including up to the minute reviews, original articles, and short reports on the latest treatment procedures and patient outcomes to help medical practitioners, allied health professionals and scientists stay up-to-date on developments.
