This study will compare hemorrhoid surgery by comparing a sutureless heating device with the old standard hemorrhoid surgery. Patients will be followed closely for wound healing and satisfaction.
Hypothesis: The sutureless device will be less painful for the patient and easier for the surgeon to perform.
|Condition or disease||Intervention/treatment||Phase|
|Hemorrhoids||Device: EnSeal Device Procedure: Ferguson Hemorrhoidectomy technique||Not Applicable|
The EnSeal Device is approved for laparoscopic surgery in ligating and dividing vascular tissue during abdominal surgery. Electrical energy is converted into heat energy and resultant simultaneous division of tissues. This allows surgery to be bloodless and sutureless. This device is being used in the current study in the treatment of hemorrhoidal disease where vascular tissue is excised in bloodless and sutureless fashion. The device is FDA-approved for laparoscopic surgery. This is currently being used in institutions throughout the United States and Europe.
This study is looking at the EnSeal device and comparing it to a gold standard hemorrhoidal procedure to see if the OR procedure can be simplified and the postoperative course improved.
The trial is a randomized, controlled, prospective study. Patients will be informed of the two techniques being studied and will be randomized in the operating room by opening up an envelope with the procedure to be employed inside. The envelopes will be numbered 1 through 100, with 50 envelopes containing a slip of paper stating that the surgery will be done using the Ferguson technique and 50 envelopes containing a slip of paper stating the that the surgery will be done using the EnSeal device. These slips of paper will be placed in the envelopes and sealed. The envelopes will be mixed up by someone not involved in the study and then numbered 1 through 100. No one will know which surgical technique will be used on the patient until the surgeon opens the envelope on the day of surgery.
Patients will be followed postoperatively in the office during week 1, week 4, and week 12. At this time, they will be assessed for postoperative complications including but not limited to: bleeding, urinary retention, infection, fecal impaction, hospital re-admission and pain. Delayed complications will also be followed including urinary retention, impaired healing, constipation, abscess, fistula formation, fissure, stenosis, fecal incontinence, and flatus incontinence. The patient's pain score will be assessed using the Universal Pain Assessment Tool, allowing the patient to describe their pain level on a scale between 1 and 10.

Active Comparator: 1. EnSeal Device
The EnSeal device cuts and seals with heat energy leaving a sutureless wound, which heals with security against bleeding. The device is able to seal blood vessels up to 7mm and hemorrhoidal vessels are much smaller than this size.
Device: EnSeal Device
Hemorrhoidectomy using the EnSeal Device, which is an instrument cuts and seals with heat energy leaving a sutureless wound, which heals with security against bleeding.
Active Comparator: 2. Ferguson Hemorrhoidectomy
The closed Ferguson hemorrhoidectomy technique is a gold standard operation that has been in existence for 50 years. This operation is done under general or intravenous sedation, and the operating surgeon uses a special clamp to go across the hemorrhoidal complex followed by excision of the hemorrhoid. Sutures that dissolve are then placed at the root of the hemorrhoid, securely tied, and then run about the clamp. The clamp is removed and then the suture tightened, then the suture line is reinforced.
Procedure: Ferguson Hemorrhoidectomy technique
The closed Ferguson hemorrhoidectomy technique is a gold standard operation that has been in existence for 50 years. This operation is done under general or intravenous sedation, and the operating surgeon uses a special clamp to go across the hemorrhoidal complex followed by excision of the hemorrhoid. Sutures that dissolve (such as 3.0 vicryl) are then placed at the root of the hemorrhoid, securely tied, and then run about the clamp. The clamp is removed and then the suture tightened, then the suture line is reinforced. This can be done from 1-3 hemorrhoidal groups at a single time.
- to examine the advantage and disadvantages of the EnSeal device as it applies to hemorrhoidal surgery and document outcomes as compared to the traditional closed Ferguson hemorrhoidectomy [ Time Frame: 1 week, 4 weeks and 12 weeks ]
