RESUMEN
BACKGROUND: Chronic venous insufficiency (CVI) is the consequence of venous valve reflux and/or venous flow obstruction and resulting venous hypertension in the lower extremities. The aim of this prospective supplement registry study was to evaluate the efficacy of compression stockings or Pycnogenol® in controlling symptoms and edema in CVI and their efficacy on microcirculatory parameters. METHODS: Two comparable groups of 30 subjects with CVI were observed for 4 months. RESULTS: Elastic compression was less tolerated than Pycnogenol® with 12 subjects being unable to follow the compression routine. No side effects due to supplementation were observed; tolerability of the supplementation was optimal. Ambulatory venous pressure (AVP) and refilling time (RT) at inclusion indicated a significant increase in venous pressure and reflux (refilling time <16 seconds). AVP and RT did not change after 4 months. Microcirculatory and clinical measurements were comparable at inclusion between the 2 groups. After 4 months, skin resting flux (RF) and skin PO

BACKGROUND: Hemorrhoids are a common problem associated with symptoms, like swelling, local thrombosis and generally with a decreased quality of life, often in otherwise healthy subjects. Hemorrhoids can be classified by grades (I to IV) according to their severity. In this registry study subjects treated with excisional hemorrhoidectomy (EH) for the first time, were included. After surgery, edema tends to complicate surgical areas causing relevant symptoms. Most hemorrhoids symptoms are related to alterations in bowel habits. Increase in diet fibers to avoid constipation, exercise, and limiting straining reduce recurrence after surgery. METHODS: The aim of the registry study was to evaluate the effects of Pycnogenol® (Horphag Research, Geneva, Switzerland) on relieving postoperative symptoms following hemorrhoidectomy. Pycnogenol® 150 mg/day was used between one month before surgery up to one month after surgery. The main postoperative symptoms were scored. RESULTS: Thirty-eight subjects completed the 60-day supplement registry study. Eighteen subjects were supplemented with Pycnogenol® in addition to the standard management (SM) and 20 subjects only received SM and were considered as controls. The two groups were comparable for age, sex and main symptoms distribution and for their clinical characteristics at inclusion. No other disease was present. The scores for pain, discomfort, and constipation were significantly lower with the supplement compared to controls (P<0.05) 10 and 30 days after surgery. In addition, the quality-of-life score was higher with Pycnogenol® (P<0.05) while bleeding (minimal, not clinically evaluable) and a possible residual anal stenosis (requiring a longer period of observation) were barely observed. A satisfactory return to activity was observed 30 days after surgery in the 18 subjects using Pycnogenol®, and in only 15 out of 20 patients (75%) in the control group (P<0.05). All Pycnogenol® subjects were able to drive and perform daily tasks in comparison with 14 out of 20 subjects in the control group. The proportion of patients that took pain medication from day 10 to 30 post-surgery was significantly lower in the Pycnogenol® group than in controls (P<0.05). CONCLUSIONS: In this post-surgical pilot, registry study, Pycnogenol® was effective in preventing and controlling postoperative symptoms after hemorrhoidectomy. To confirm the results, more cases are needed, including different surgical methods and clinical conditions. Mucosal and cutaneous edema and perianal swelling - generally seen after surgery - seem to be clearly reduced with Pycnogenol® and the supplement intake was associated with a more regular and pain-controlled convalescence and healing.
