This is a single center randomized clinical trial comparing Ligasure Hemorrhoidectomy and Open Hemorrhoidectomy for the treatment of prolapsing haemorrhoids. The primary aim of the study is to evaluate symptoms related to hemorrhoids one year postoperatively, according to a hemorrhoidal disease symptom score (HDSS).
Secondary endpoints are patient satisfaction with the operation, Health related Quality of Life and effect on anal continence.

Active Comparator: Minimal open hemorrhoidectomy
Patients randomized to Minimal open hemorrhoidectomy
Procedure: Open Haemorrhoidectomy
Patient operated in the lithotomy position. The external components are grasped by clamps using gentle traction. Diathermy is used for dissection and hemostasis. The skin is incised midway to one-third of the distance from the top of the pedicle, thus, minimizing the skin excision. The subdermal fascia continuing into a submucosal fascia covering the internal anal sphincter is identified as are fibers passing between the hemorrhoid (H) and this fascia. The H is dissected free from the underlying internal sphincter in this plane, leaving the sphincter unharmed. The anal mucosa is incised at the transition from anal mucosa to hemorrhoidal mucosa and only anal mucosa overlying the H is excised. Only the caudal part of the H is excised. With the H held with gentle traction it is divided at the anal orifice. There will thus be a residual part of the H intra-anally with its caudal end 1-2 cm proximal to the anal orifice.
Active Comparator: LigaSure hemorrhoidectomy
Patients randomized to LigaSure hemorrhoidectomy
Procedure: LigaSure Hemorrhoidectomy
Patient is operated in the lithotomy position. The main haemorrhoidal (H) masses are identified and delineated. The H are prolapsed out from the anal canal with Allis clamps or similar pick up forceps. Tension is applied to visualise the junction between the nodule and the mucosal wall (internal) or the perianal tissue (external). A small V-shaped anodermal seal is performed by applying the LigaSure (LS) forceps close to the edge of each pile. The seal is then transacted with scissors along the line of coagulum. Care should be taken to limit the amount of tissue removed to minimize the stricture risk. Repeated applications of the device are performed and the excision is continued into the anal canal, lifting the pile from the internal anal sphincter to the level of the vascular pedicle that is finally sealed by LS and divided.
- Hemorrhoidal symptoms assessed by the Hemorrhoidal Disease Symptom Score (HDSS). [ Time Frame: 1 year postoperatively ]The HDSS consists of five items on patient-reported frequency of pain, itching, bleeding, soiling and prolapse. Each symptom graded on a five-point scale (0=never, 1=less than once a month, 2=less than once a week, 3=1-6 days per week, 4=every day / always), giving a total score ranging from 0-20. Zero meaning no symptoms. (See reference).
- Patient satisfaction assessed by a seven grade Likert Scale. [ Time Frame: Preoperatively (baseline) and 1 year postoperatively ]At follow-up patients grade their satisfaction with the operation on a seven-point Likert scale (1= very unsatisfied, 7 = very satisfied).
- Hemorrhoidal affection of the patient's daily life assessed by Short Health Scale adapted to hemorrhoidal disease (SHSHD). [ Time Frame: Preoperatively (baseline) and 1 year postoperatively ]
SHSHD consist of four questions graded on a 7-point Likert scale. The questions deal with how the patients symptoms caused by hemorrhoids affect the patients daily life.
- - Overall symptom load (1 = no symptoms, 7 = severe symptoms),
- - Interference with daily activities (1 = not at all, 7 = interfere to a very high degree)
- - Worries caused by HD (1 = no concerns, 7 = constant concerns)
- - General well-being (1 = very good, 7 = very bad) The points of each question are summed giving a total score ranging from 4 to 28. (See reference).
- Anal continence (gas and solids) assessed by the Wexner incontinence scale. [ Time Frame: Preoperatively (baseline) and 1 year postoperatively ]
Wexner incontinence scale consists of five questions on fecal incontinence graded on a five-point Likert scale from 0 to 4.
The points of each question are summed giving a total score ranging from 0 to 20. Zero meaning no incontinence and 20 complete incontinence.
- Fecal continence assessed by the Revised Fecal Incontinence Scale (RFIS). [ Time Frame: Preoperatively (baseline) and 1 year postoperatively ]RFIS consists of five questions on fecal incontinence graded on a five-point Likert scale from 0 to 4. The points of each question are summed giving a total score ranging from 0 to 20. Zero meaning no fecal incontinence and twenty total fecal incontinence.
