Brief Summary:
A wide variety of methods has been proposed for treating hemorrhoidal disease with excisional hemorrhoidectomy remaining the gold standard The aim of this trial is to assess the safety and effectiveness of the HAL-RAR technique in treating hemorrhoidal disease Arterial ligation was performed by using the highest doppler signal to locate the site of the hemorrhoidal artery in combination with RAR in order to reposition redundant rectal mucosasubmucosa that prolapses to its original anatomical location leading to resolution of symptoms
This is a retrospective study from January 2010 to November 2019 of patients who underwent HAL-RAR for hemorrhoidal disease Demographics degree of disease length of hospital stay postoperative pain complications urinary retention dyschezia bleeding necrosis of a hemorrhoid anal discomfort sensation of fullness and recurrence were recorded Patients were followed-up at postoperative day 1 and 8 and at 1 6 and 12 months The main outcome of the study was recurrence Secondary outcomes included postoperative complications postoperative pain and patient-assessed resolution of symptoms

Detailed Description:
This is a retrospective single-institution study conducted from January 2010 to November 2019 Grade of hemorrhoidal disease was assessed according to Golighers classification Patients with grade II resistant to conservative treatment grade III and IV hemorrhoidal disease that underwent the HAL-RAR technique were included in the study Patients with grade II disease presented a small degree of prolapse Non-surgical techniques such as rubber-band ligation or injection of sclerosing agents were not performed prior to the HAL-RAR operation since this is not a common practice in our institution Conservative treatment for grade II hemorrhoids included diet rich in fiber lifestyle modifications increased fluid intake improved anal hygiene avoiding staining and constipation the use of phlebotonics and other topical ointments that contained a combination of local anesthetics corticosteroids and antiseptics designed to relieve symptoms of pruritus and discomfort
The study was reviewed and approved by the institutions ethics committee Detailed informed consent was obtained from all patients before the operative procedure Exclusion criterion included age 18 years pregnancy coagulation disorders patients with major comorbidities American Society of Anesthesiologists ASA 3 psychiatric conditions preventing collaboration and follow-up other concomitant anorectal disease rectal prolapse anal fissure anal stenosis perianal fistula or abscess fecal incontinence and previous pelvic radiotherapy Preoperative clinical assessment and classification for all patients included complete medical history particularly underlining hemorrhoidal disease-related symptoms physical examination proctoscopy and rigid sigmoidoscopy Further investigation was performed when necessary
Demographic data degree of hemorrhoidal disease length of hospital stay perioperative and postoperative data were recorded Clinical assessment and surgery were performed by two of the authors trained and experienced with the technique Patients did not receive a solid diet after 1000pm the night before surgery Preoperative preparation included one or two phosphate enemas before the procedure Antibiotic prophylaxis was not considered mandatory and was not administered The severity of pain was self-evaluated by the patients using a visual analogue scale VAS with 0 indicating the absence of pain and 10 the worst possible pain Data about analgesic consumption was also recorded Postoperatively intravenous Paracetamol 3gr and Parecoxid 80mg was administered daily and in cases of severe pain Tramadol 500mg was given upon request Patients were discharged when adequate pain control was achieved They were examined by the surgeon to rule out early complications and ensure the outcome of the operation Patients were advised to avoid prolonged straining and heavy physical activity for 1 month and to consume at least 2 liters of water per day and a diet rich in fiber supplemented by the oral consumption of stool softeners After discharge oral analgesics were prescribed that consisted of nonsteroidal anti-inflammatory agents and oral narcotics Patients were followed-up on postoperative day 1 and 8 and at 1 6 and 12 months and evaluated with a proctologic examination A patient directed diary card to assess the resolution of symptoms was implemented Recurrence was evaluated after physical examination and defined as relapse of symptoms such as bleeding or prolapse often daily requiring manual reduction The main outcome of the study was recurrence Secondary outcomes included postoperative complications postoperative pain and patient-assessed resolution of symptoms Continuous variables are presented as median values and range and categorical variables as numbers and percentages
Surgical technique The operation was performed with the patient in the lithotomy position under general or spinal anesthesia according to the patients preference in consultation with the anesthesiologist Perianal block was not offered as an alternative The region is then treated with an antiseptic solution After lubrication with xylocaine gel the anal canal is dilated to a width of two fingers to allow insertion of the proctoscope The HAL proctoscope equipped with a doppler transducer HAL II Doppler AMI Feldkirch Austria which is orientated just below the proctoscopes lateral ligation window allows the identification and the selective ligation of the hemorrhoidal artery In addition a built-in light source provides illumination for easy placement of sutures under direct vision As the submucosal terminal branches of the superior hemorrhoidal artery are best identified with the Doppler signal 2cm above the dentate line the proctoscope was inserted 5-6 cm above the anal verge for best localization The operation started and ended at the 12 oclock position The proctoscope was then rotated clockwise in search of the 6 main terminal branches usually located at 1 3 5 7 9 and 11 oclock Once identified the proctoscope was slowly withdrawn distally until the best Doppler signal was obtained Arterial ligation was then performed with a Z suture using 2-0 polyglycolic acid and 58-inch needle A knot-pusher was used to secure the suture The lateral ligation window in the proctoscopes lumen was used to calculate the exact depth of the transfixed sutures By inserting the tip of the needle holder inside the pivot hole before suturing it ensured a maximum depth of 6mm primarily involving the mucosa and submucosa avoiding the perforation of the entire rectal wall Eradication or significant reduction of the Doppler signal when tying the suture confirmed the successful arterial ligation The proctoscope was rotated clockwise at the same level to locate further arteries Once a full rotation had been completed the procedure was repeated 15mm below the first series of sutures The number of arterial ligations ranged from 6 to 10 After completion of the arterial ligation the RAR procedure known as mucopexy was performed where hemorrhoidal prolapse was detected Using the same proctoscope the outer sleeve is removed in order to expand the operating window and expose a wider rectal mucosal area The prolapsing tissue comes under direct vision inside the proctoscopes lumen RAR is carried out with a continuous suture along the longitudinal axis in a proximal-to-distal direction in the lower part of the rectum with the same 2-0 polyglycolic acid and 58-inch needle The continuous suture of the mucosa and submucosa can be performed repeatedly according to the size and extent of the prolapse and must always entrap the site of the hemorrhoidal artery with suture above and below It is important to ensure 5mm distance between each suture to avoid tissue ischemia and ensure sufficient venous outflow from the hemorrhoids The continuous suture ends up to 1cm proximal to the dentate line sparing the anal canal avoiding postoperative pain After securing the continuous suture the redundant rectal mucosasubmucosa that prolapses is repositioned to its original anatomical location The number of RAR performed ranged from 1 to 5 while special attention was given to stay above the dentate line
