Study of Pain Control in Hemorrhoidectomy
HemorrhoidPatients will get an injection of either SKY0402 or placebo during hemorrhoid surgery, and their pain and pain medicine use will be monitored.

Topical Analgesia Post-Haemorrhoidectomy
Hemorrhoid PainHemorrhoidsSymptomatic haemorrhoids, or piles, have significant effects on quality of life. The treatment for advanced disease is surgical excision (haemorrhoidectomy) which is extremely effective. However, pain following haemorrhoidectomy is known by all to be a miserable experience and current treatment is not very effective. We have formulated a new cream treatment which targets three theorised mechanisms of pain after haemorrhoidectomy. We will test the effectiveness of the treatments with a multi-centred randomised controlled factorial trial with four parallel double-blinded arms containing different combinations of the active agents. The outcomes include pain scores, amount of analgesia required and time to return to work. The results of our study could provide evidence of an effective treatment for post haemorrhoidectomy pain. The treatment may provide considerable benefit to patients undergoing this surgical procedure.

HET Bipolar System: Validation of Outpatient Hemorrhoid Treatment
HemorrhoidsPurpose: The current study aims to evaluate the safety and effectiveness of the HET™ Bipolar System (Medtronic, Boulder, CO) for the treatment of grade I-II hemorrhoids in a prospective pilot study. This device was evaluated retrospectively in a limited cohort of 23 patients previously. Methods: Patients seen at a colorectal clinic in a single institution with grade I-II hemorrhoids are offered to participate in a prospective pilot trial. The HET device is a modified anoscope equipped with LED lighting, a tissue clamping mechanism and a bipolar energy source used to treat multiple hemorrhoidal columns in one sitting. Three columns of hemorrhoids are treated with 2 heat energy applications per column. The primary outcome is the treatment effect on hemorrhoid symptoms of bleeding, pain, prolapse, itching, and soiling. This is measured with a patient completed questionnaire documenting each symptom's frequency from 0 to 3 (i.e. 0 is < 1x/month; 3 is daily) before therapy and at 3 weeks and 6 month follow-up. Post-treatment pain scores were recorded using the visual analog scale (VAS).

Safety and Efficacy of Hydrocortisone and Lidocaine Treatment of Grade I and II Hemorrhoids
HemorrhoidsThe objectives of this study are to assess the potential contribution of lidocaine hydrochloride or hydrocortisone acetate, alone or in combination, in topical cream preparations in the treatment of Grade I or II hemorrhoids and to demonstrate the safety and efficacy of the test articles when applied twice daily for 14 days in subjects with Grade I or II hemorrhoids. These products reflect common drug combinations of lidocaine hydrochloride or hydrocortisone acetate found in many prescription hemorrhoid products.
