Doppler-guided hemorrhoidal laser procedure for the treatment of symptomatic hemorrhoids: experimental background and short-term clinical results of a new mini-invasive treatment

Multilayered numerical modelling of bio-thermal aspects during laser assisted treatment of internal haemorrhoid developed in rectum

Haemorrhoids are swollen blood vessels developed around the anus. Internal haemorrhoids are generally not visible from outside due to its growth inside the rectum and it is generally considered as painless. However, a prolapsed internal haemorrhoid may cause discomfort, pain and irritation. For the treatment of internal haemorrhoid, laser assisted therapy would be helpful due to its rooted advantages such as post-surgery minimal pain, lesser bleeding, quicker healing, shorter recovery period, shorter surgical and overall treatment duration, lower risk of recurrence and least risk of post-surgical infections. The genesis of present research work deals with the development of mathematical modelling to capture the bio-thermal response during laser assisted therapy of internal haemorrhoid developed in the rectum. The explicit form of finite difference method is employed as numerical tool for the mathematical study and the physical domain is considered as multilayered tissue (three different layers of rectum: muscle, submucosa and mucosa). A Gaussian laser beam is considered as heat source to destroy the abnormal growth inside the rectum. Temperature variation in multi-layered tissue is investigated for laser heat input and absorption radius along the temporal and spatial coordinate. Temperature drop has been evidenced in the interfaces of multi-layered rectum tissue. The research outcome is verified with the published numerical model with negligible variation.

Shifting Paradigms in Hemorrhoid Management: The Emergence and Impact of Cap-Assisted Endoscopic Sclerotherapy

Hemorrhoidal disease (HD) is a prevalent proctological condition that has puzzled people since ancient times, and the most common symptom is painless bleeding. Traditional treatments include conservative treatment, nonsurgical office-based treatments, and surgery. Sclerotherapy is one of the oldest forms of nonoperative intervention and is widely used to treat internal hemorrhoids with the development of endoscopy technology. However, sclerotherapy is always accompanied by complications such as bleeding, pain, abscess, etc., when the sclerosant is injected into the wrong site. Cap-assisted endoscopic sclerotherapy (CAES), a new minimally invasive technology, was first time coined in 2015 for the treatment of hemorrhoidal disease. The left-posterior-right-anterior (LPRA) anus positioning method under endoscopy provides reliable methodological support for advancing hemorrhoidal treatment via endoscopy. The current trend is that treatment for HD has shifted from being performed predominantly by the Department of Proctology Surgery to being managed mostly by the Department of Gastroenterology. This review reviewed the shifting paradigms of sclerotherapy for HD and discussed the emerging development of CAES.

Outcomes of laser hemorrhoidoplasty for grade II-IV hemorrhoidal disease in Bangladesh

Background

Laser hemorrhoidoplasty is a minimally invasive procedure to treat hemorrhoids and has shown better outcomes. Less is known about its utility in a lower middle-income country; Bangladesh.

Method

Between March 2023 and December 2023, 86 patients with grade II-IV hemorrhoids underwent laser hemorroidoplasty. Follow up was assessed on 1st week, 2nd week, and 6th week including pain, satisfaction, symptom improvement, incapacity for work, complications, reduction, and recurrence.

Results

The study included 86 patients, with a higher proportion of male participants (73.3%) and a mean age of 55.43±13.6 years. The majority of subjects (68.60%) had grade 3 hemorrhoids. The average surgery duration was 14.70±4.70 minutes All individuals experienced substantial decreases in the size of their hemorrhoids (100%) and reported high levels of satisfaction after the operation (97.7%). The use of the Wilcoxon signed-rank test demonstrated a statistically significant reduction in both the Visual Analog Scale (VAS) and Patient Global Impression of Improvement (PGI-I) ratings during the three subsequent observation periods (1st week, 2nd week, and 6th week). The 6th week complication rate was 19.8%. Additional mucopexy was performed on all patients with grade IV and three patients with grade III hemorrhoids.

Conclusion

Laser hemorroidoplasty is a day-care procedure, that is safe and efficacious and can be used in rural area settings with good patient satisfaction. Mucopexy is required in some cases of large hemorrhoidal mass to prevent recurrence.

Laser technology in proctological diseases: is it really the wave of the future?

Different types of lasers have been applied for various proctological conditions. We discuss about published articles regarding the application of lasers, with concern about evidence-based use of these techniques and technologies. We performed a literature search about laser treatments for proctological conditions. 55 studies were included for the final revision. Meta-analysis of data was not performed because of heterogeneity of study designs and outcome measures. A scoping review was performed. Laser treatments for hemorrhoids require a shorter operative time and show less postoperative pain and bleeding compared to conventional hemorrhoidectomy, but are more expensive. Studies are heterogeneous in design, endpoints, postoperative assessment, length of follow-up and outcome measures. Only 3 RCTs are available and only three studies evaluate long-term outcomes. FiLaC (fistula laser closure) was initially described in 2011 for the treatment of anal fistula. In the published studies the reported healing rates vary between 20 and 82%, and the ideal indication is yet to be defined. Studies with long-term follow-up are lacking. SiLaT (sinus laser treatment) applied the technology used for FiLaC to the treatment of pilonidal sinus disease. This technique had less perioperative pain and shorter hospital stay, but a lower primary healing rate when compared to traditional techniques. Available data is very limited, and no randomized trials are published to date. Laser assisted techniques are a viable, minimally invasive, but expensive option for the treatment of several proctological conditions. Further researches are needed to assess if patients could benefit of their use, and for what indication.

Hemorrhoid laser dearterialization: systematic review and meta-analysis

Hemorrhoidal disease is a common and troublesome condition. Excisional hemorrhoidectomy can assure the best chance of cure but it is hampered by postoperative pain and potential long-term morbidity therefore minimally invasive techniques have been developed. Since 2009 a doppler-guided hemorrhoidal dearterialization with laser (the hemorrhoidal laser procedure; HeLP) has been proposed to control symptoms without significant sequelae. The aim of this systematic review is to analyze the benefits and disadvantages of HeLP for symptomatic hemorrhoids. The Medline/PubMed, Embase, and Cochrane library databases were searched from January 2010 to March 2022, language was restricted to English and documents to the full text. Randomized and non-randomized, prospective and retrospective cohort studies were included. Risk of bias assessment was performed using the Risk of bias for non-randomized studies (ROBINS-I) and the RoB2 Tool for randomized clinical trial. Primary outcome was to assess the efficacy of HeLP on symptoms' resolution. Secondary objectives were postoperative pain and complications, comparison with other interventional techniques, and evaluation of long-term recurrence. Whenever possible, a meta-analysis was conducted. The GRADE approach was employed to assess the certainty of evidence. We included six non-randomized and one randomized study. HeLP improved or resolved preoperative symptoms in 83.6 to 100% of patients during follow-up. In the randomized study symptoms resolved in 90% of patients after HeLP and 53.3% after rubber band ligation as comparator. Published data indicate that HeLP is effective, relatively safe, with limited recurrence rate, after a short to medium follow-up. The quality of evidence was however low. There is a paucity of studies assessing the benefits or harms of laser dearterialization for the treatment of hemorrhoids and randomized trials are furthermore rare, therefore trials with adequate power and proper design, assessing the advantages and disadvantages of HeLP versus other minimally invasive techniques, are needed. Furthermore, studies evaluating long-term follow-up are wanted.

The effects of laser procedure in symptomatic patients with haemorrhoids: A systematic review

Purpose

Haemorrhoids are normal structures in the human body, only seen as pathological when symptomatic. Nowadays, new techniques have surfaced using a diode laser which, after locating the target arteries, blocks the blood flow while hitting and shrinking the local mucosa/submucosa at a depth of 4 mm. Our work aimed to give a broad view over this new technique and its consequences in the post-operative follow-up with a systematic review.

Methods

EMBASE and MEDLINE databases were consulted, retrieving clinical trials, which mentioned the use of 980 nm diode laser on the treatment of haemorrhoids.

Results

Ten clinical trials analyzing the post-operative effects of laser haemorrhoidectomy were selected, including 2 randomized controlled clinical trials and 1 controlled clinical trial. The overall quality of the trials was low, indicating a high risk of bias.

Conclusion

The laser haemorrhoidectomy procedure revealed a high therapeutic potential, considering the reduced number of postoperative complaints (bleeding/pain), the high symptom resolution and the reduced recurrence, albeit the high heterogeneity between the studies in terms of reported results. Future investigations with higher quality and controlled double-blinded studies obtaining better-categorized results should be conducted in order to better evaluate this procedure and compare it to the current paradigm.

Comprehensive literature review of the applications of surgical laser in benign anal conditions

Surgery for benign anal conditions is a common practice and is usually followed by a good outcome. The present review aimed to summarize the emergence and evolution of different laser techniques used for the treatment of benign anal conditions and report their current outcome. PubMed and Scopus were searched for studies that assessed the use of laser in benign anal conditions. Anal conditions reviewed were hemorrhoids, anal fistula, anal warts, anal stenosis, and anal fissure. The full text of the studies retrieved was summarized in a narrative and tabular form. Laser techniques used for the treatment of hemorrhoidal disease were laser open hemorrhoidectomy, laser hemorrhoidoplasty, and Doppler-guided hemorrhoidal laser dearterialization. Resolution of hemorrhoidal symptoms was reported in 72-100% of patients after laser treatment. YAG laser, fistula laser closure, and photodynamic therapy have been used for the treatment of anal fistula with success rates ranging from 20 to 92.6%. Anal warts can be treated with photodynamic therapy with or without YAG or CO2 laser with a success rate up to 88%. A few studies reported the use of laser in the treatment of chronic anal fissure and anal stenosis. The use of laser in the treatment of benign anal conditions is associated with promising outcomes. Laser was most assessed in hemorrhoidal disease and anal fistula and showed more consistent success rates with hemorrhoidal disease than with anal fistula. Preliminary reports assessed the outcome of laser treatment in other conditions as anal fissure and warts with acceptable outcomes.

Hemorrhoid laser procedure (HeLP) for second- and third-degree hemorrhoids: results from a long-term follow-up analysis

We aimed to analyze the results of 5-year consecutive use of the hemorrhoidal laser procedure (HeLP) in patients with second- to third-grade hemorrhoids with minimal or moderate mucosal prolapse. A total of 189 patients were treated between April 2012 and October 2017. We reported perioperative complications, postoperative pain, improvement of hemorrhoids grade, and relapse of hemorrhoidal disease (HD). Improvement of symptoms was assessed using the Patient Global Improvement (PGI) Scale. No severe intraoperative complications were observed. The median follow-up was 42 months (range 6-62 months). Pain after surgery was absent in 94% of patients. No cases of rectal tenesmus or alterations of defecation habits were reported. Symptoms and HD improvement reached a "plateau" at 3 to 6 months following surgery. We observed a significant decrease in HD degree, occurrence of bleeding, pain, itching, and acute HD. Complete resolution of HD was reported in > 60% of patients 1 year after surgery. The individual level of improvement in symptoms was consistent (very much and much improved, according to PGI-I score) for about 90% of patients during the follow-up. This study confirmed that the HeLP is a safe, painless, and effective procedure for the treatment of HD in selected cases.

Doppler-guided hemorrhoidal dearterialization with laser (HeLP): indications and clinical outcome in the long-term. Results of a multicenter trial

BACKGROUND

Doppler-guided hemorrhoidal laser procedure consists of sutureless closure of terminal branches of the superior hemorrhoidal artery by laser energy. Clinical results of patients treated with this procedure were analyzed at the completion of 2-year follow-up. Primary endpoint was resolution of symptoms and secondary endpoints were recurrence rate, type of recurrences, re-operation rate, and potential predictive factors for failure.

METHODS

Bleeding was assessed on a score from 0 to 4 (none = 0; < 1/month = 1; 1/week = 2; > 1/week = 3; 3-4/week = 4), frequency of hemorrhoid-related symptoms with a score of 0-3 (2/year = 1; 3-5/year = 2; < 5/year = 3). Constipation and fecal incontinence were assessed by means of validated scores. Quality of life and pain at defecation were assessed using a visual analog scale of 0-10 (0 = worst possible-10 = best possible quality of life and 0 = no pain-10 = worst pain imaginable, respectively). Recurrence rate and need for re-operation were reported. Potential predictive factors of failure were analyzed by means of univariate analysis.

RESULTS

Two-hundred-eighty-four patients (183 males, 101 females; mean age: 47.5 years) were included in the trial; 8 patients were lost at follow-up. Analysis of 276 patients who completed the 2-year follow-up showed an overall resolution of symptoms in 89.9% (248/276) of patients. Statistically significant improvement of quality of life, pain reduction, bleeding and frequency of acute symptoms were reported. Of 28 patients with persistent or recurrent symptoms, 12 had pain (4.35%), 10 had bleeding (3.6%) and 6 had increasing prolapse at defecation (2.2%). Eleven out of twenty-eight patients required additional surgery. Constipation and III-IV grade hemorrhoids were associated with statistically significant higher failure rates (p = 0.046 and 0.012, respectively). Better results were reported in patients reporting preoperative high-grade pain at evacuation.

CONCLUSIONS

The Doppler-guided hemorrhoidal laser procedure showed efficacy at long-term follow-up. It can be considered as 'first-line' treatment in patients with low-grade hemorrhoids suffering from bleeding, pain and recurrent acute symptoms in whom conservative treatment failed.

Evolution of Surgical Management of Hemorrhoidal Disease: An Historical Overview

Hemorrhoidal disease (HD) is the symptomatic enlargement and/or distal displacement of the normal hemorrhoidal cushions and is one of the most frequent diseases in colorectal surgery. Several surgical or office-based therapies are currently available, with the aim of being a more tailored approach. This article aimed to elucidate the historical evolution of surgical therapy for HD from ancient times, highlighting the crucial steps, controversies, and pioneers in the field. In contrast with the previous literature on the topic that is often updated to the 1990s, with the introduction of stapled hemorrhoidopexy and transanal hemorrhoidal dearterialization, this article describes all new surgical and office-based treatments introduced in the first 20 years of the 2000s.

Laser utility in the treatment of hemorrhoidal pathology: a review of literature

Hemorrhoidal disease is a common reason for consultation in proctology. It can be treated in several ways (medical, endoscopic, and surgical). Laser treatment has been described since 1960 and has developed in recent years. The purpose of this literature review was to study the results of laser treatment of hemorrhoids and to compare them with those of surgical methods. We performed a systematic search of the literature by querying the Medline, Google Scholar, and Cochrane Library databases. Retrospective studies and case reports were excluded. We selected 11 studies both techniques HeLP (hemorrhoid laser procedure) and LHP (laser hemorrhoidoplasty procedure). The total number of patients was 1179 including 1059 patients treated with laser and 120 treated surgically within the context of comparative studies. The age of the patients varies between 18 and 74 years old. HeLP laser treatment was significantly superior to surgical treatment in terms of postoperative pain (p < 0.001), hemorrhoidal disease downgrading (p < 0.001), and postoperative satisfaction (p < 0.001). Similarly, LHP laser treatment was significantly superior to surgical treatment in terms of operative duration (p < 0.00001), intraoperative bleeding (p < 0.00001), postoperative pain at H12 and H24 (p < 0.00001 and p = 0.0003), and postoperative bleeding rate (p < 0.001). The laser represents a revolution in the field of proctology mainly in the treatment of hemorrhoidal pathology. It is a safe, effective, and less painful mini-invasive technique. More rigorous studies will be needed to better evaluate this technique.

Evaluation of a Minimally Invasive Bipolar Coagulation System for the Treatment of Grade I and II Internal Hemorrhoids

BACKGROUND

Hemorrhoids are common and affect mainly the young and middle-aged populations. Current guidelines recommend treating grade I and II hemorrhoids with office-based procedures. These therapies usually require multiple applications. Hemorrhoid energy therapy treats the hemorrhoids at 1 treatment session.

OBJECTIVE

The purpose of this study was to evaluate the safety and efficacy of hemorrhoid energy therapy.

DESIGN

This was a prospective pilot study evaluating patients with symptomatic grade I and II internal hemorrhoids.

SETTINGS

The study was conducted at a tertiary academic center.

PATIENTS

Patients over the age of 18 years with chronic, symptomatic grade I and II internal hemorrhoids who failed 2 weeks of conservative therapy were enrolled between July 2015 and January 2019. Exclusion criteria included patients with grade III or IV internal hemorrhoids, external hemorrhoids, nonhemorrhoidal GI bleeding, active proctitis, and IBD.

INTERVENTIONS

Hemorrhoid energy therapy was administered in clinic, and 2 postprocedure visits were completed. A pretreatment hemorrhoid symptom score was obtained from each patient. A visual analog score was assessed posttreatment.

MAIN OUTCOME MEASURES

The primary end point was to evaluate the effect of hemorrhoid energy therapy on hemorrhoid symptoms and its safety. The secondary end point was evaluation of postprocedural pain.

RESULTS

A total of 35 patients were enrolled. The mean duration of hemorrhoid symptoms was 3.3 ± 6.4 years, and rectal bleeding and hemorrhoidal prolapse were the most common symptoms. After the procedure, patient hemorrhoid symptom scores decreased from mean 5.5 to 1.4. The mean immediate postprocedural visual analog score was 2.4 ± 2.1 and decreased to <1.0 after 14 days.

LIMITATIONS

The limitations include lack of comparative groups, single-center design, and small cohort of patients.

CONCLUSIONS

The application of hemorrhoid energy therapy in the treatment of grade I and II internal hemorrhoids is safe and results in reduction of symptoms, low rate of short-term complications, and minimal pain.

Non-excisional laser therapies for hemorrhoidal disease: a systematic review of the literature

Non-excisional laser therapies are emerging treatment for grades II and III hemorrhoidal disease (HD). However, so far, their efficiency is based on low-level evidence. Therefore, we aimed to systematically review the efficiency of non-excisional laser therapies for HD. MEDLINE/Pubmed, Web of science, Embase, and Cochrane were searched from database implementation until the April 17th, 2020. We included studies reporting at least one of surgical indicators of postoperative outcomes of laser therapies, encompassing laser hemorrhoidoplasty (LH) and hemorrhoidal laser procedure (HeLP). Fourteen studies describing LH and HeLP were included, representing 1570 patients. The main intraoperative complication was bleeding (0-1.9% of pooled patients for LH, 5.5-16.7% of pooled patients for HeLP). Postoperative complications occurred in up to 64% of patients after LH and 23.3% after HeLP. Resolution of symptoms ranged between 70 and 100% after LH and between 83.6 and 90% after HeLP. Moreover, four randomized controlled trials included in our review reported similar resolution after LH compared with hemorrhoidectomy or mucopexy and after HeLP compared with rubber band ligation. Recurrence rate was reported to range between 0 and 11.3% after LH and between 5 and 9.4% after HeLP. When compared with hemorrhoidectomy, LH showed conflicting results with one randomized controlled trial reporting similar recurrence rate, but another reporting decreased recurrences associated with hemorrhoidectomy. Laser therapies showed lower postoperative pain than hemorrhoidectomy or rubber band ligation. LH and HeLP are safe and effective techniques for the treatment of grades II and III HD.

Still a Case of "No Pain, No Gain"? An Updated and Critical Review of the Pathogenesis, Diagnosis, and Management Options for Hemorrhoids in 2020

The treatment of haemorrhoids remains challenging: multiple treatment options supported by heterogeneous evidence are available, but patients rightly demand a tailored approach. Evidence for newer surgical techniques that promise to be less painful has been conflicting. We review the current evidence for management options in patients who present with varying haemorrhoidal grades. A review of the English literature was performed utilizing MEDLINE/PubMed, Embase, and Cochrane databases (31 May 2019). The search terms (haemorrhoid OR haemorrhoid OR haemorrhoids OR haemorrhoids OR "Hemorrhoid"[Mesh]) were used. First- and second-degree haemorrhoids continue to be managed conservatively. The easily repeatable and cost-efficient rubber band ligation is the preferred method to address minor haemorrhoids; long-term outcomes following injection sclerotherapy remain poor. Conventional haemorrhoidectomies (Ferguson/Milligan-Morgan/Ligasure haemorrhoidectomy) still have their role in third- and fourth-degree haemorrhoids, being associated with lowest recurrence; nevertheless, posthaemorrhoidectomy pain is problematic. Stapled haemorrhoidopexy allows quicker recovery, albeit at the costs of higher recurrence rates and potentially serious complications. Transanal Haemorrhoidal Dearterialization has been promoted as nonexcisional and less invasive, but the recent HubBLe trial has questioned its overall place in haemorrhoid management. Novel "walk-in-walk-out" techniques such as radiofrequency ablations or laser treatments will need further evaluation to define their role in modern-day haemorrhoid management. There are numerous treatment options for haemorrhoids, each with their own evidence-base. Newer techniques promise to be less painful, but recurrence rates remain an issue. The balance continues to be sought between long-term efficacy, minimisation of postoperative pain, and preservation of anorectal function.

[Submucosal laser ablation of internal hemorrhoids]

OBJECTIVE

To analyze efficacy and safety of submucosal laser ablation of internal hemorrhoids (SLT).

MATERIAL AND METHODS

Systematic review included 10 articles published in electronic databases PubMed, Cochrane Library, Elibrary until January 2019. There were only full-text publications from prospective clinical trials devoted to submucosal laser ablation in the treatment of hemorrhoids. Isolated SLT was used in 4 trials, combination with other minimally invasive procedures was reported in 6 reports.

RESULTS

SLT was predominantly used in the treatment of hemorrhoids grade 2-3. Efficacy of procedure was 91.1-100% after 6 months and 87.5-100% after 12 months. Intra- and postoperative complications included intraoperative bleeding (8.4%), perianal and external piles edema (8.2%), postoperative bleeding (2.7%), urinary retention (1.2%), anal fistula (0.6%), perianal abscess (0.14%).

CONCLUSION

Submucosal laser ablation is quite effective and safe option for treatment of hemorrhoids grade 2-3. However, further researches are required considering the absence of clear recommendations on laser beam parameters, indications for procedure and data on long-term outcomes.

Consensus statement of the Italian society of colorectal surgery (SICCR): management and treatment of hemorrhoidal disease

Hemorrhoidal disease (HD) is the most common proctological disease in the Western countries. However, its real prevalence is underestimated due to the frequent self-medication.The aim of this consensus statement is to provide evidence-based data to allow an individualized and appropriate management and treatment of HD. The strategy used to search for evidence was based on application of electronic sources such as MEDLINE, PubMed, Cochrane Review Library, CINAHL, and EMBASE.These guidelines are inclusive and not prescriptive.The recommendations were defined and graded based on the current levels of evidence and in accordance with the criteria adopted by American College of Chest Physicians. The recommendations were graded A, B, and C.

Hemorrhoid laser procedure with suture-pexy (HeLPexx): a novel effective procedure to treat hemorrhoidal disease

BACKGROUND

The hemorrhoid laser procedure with suture-pexy (HeLPexx), consisting of Doppler-guided hemorrhoidal dearterialization with laser and the addition of anal mucopexy, is a novel non-excisional procedure to treat hemorrhoids. The aim of the present study was to describe the technique and report the clinical and long-term results.

METHODS

A prospective study was conducted on patients with grade III hemorrhoids who had HeLPexx from January 2012 to February 2018. Pre- and postoperative assessment included a thorough clinical examination, constipation and incontinence scoring systems and a symptom questionnaire which was administered at all patients before surgery and at each follow-up visit to evaluate bleeding, prolapse, manual reduction, discomfort or pain, and impact on quality of life. Each symptom had a score between 0 and 4, (0 indicates no symptoms and 4 indicates daily symptoms). The sum of the score for each symptom constituted the Hemorrhoid Symptom Score. Resolution of symptoms, pain, morbidity, need for further medical and/or surgical therapy were also recorded.

RESULTS

One hundred and seventy consecutive patients with grade III hemorrhoids [74 females; mean age 49.5 years (range 22-79) years] were included. Median length of follow-up was 36 (range 12-72) months. Postoperative morbidity included urinary retention (7 patients, 4.1%), bleeding not requiring transfusion (1 patient, 0.6%) and thrombosis of hemorrhoidal piles (2 patients, 1.2%). The mean postoperative pain VAS score at 1 week postoperatively was 1.8 ± 1.1 (range 0-5) and 12 (7%) patients used pain medications for more than 1 week postoperatively while none of the patients reported any pain by the end of the third week postoperatively. The Hemorrhoid Symptom Score significantly improved from 15.83 ± 3.04 to 1.3 ± 2.4 (p ≤ 0.001) and showed a statistically significant improvement in all items. Recurrent symptoms were reported in 12 patients (7%) who required further treatment. Severe chronic constipation prior to surgery was found to be a predictive factor of failure (p = 0.04).

CONCLUSIONS

HeLPexx appears to be safe and effective for treatment of symptomatic hemorrhoids. Further studies are needed to confirm our results.

Short- and long-term outcomes of laser haemorrhoidoplasty for grade II-III haemorrhoidal disease

AIM

Laser haemorrhoidoplasty is associated with minimal postoperative pain and good symptom improvement in the short-term. However, less is known about its long-term efficacy. This study aims to determine the short- and long-term outcomes of laser haemorrhoidoplasty.

METHOD

Between October 2010 and May 2012, 50 consecutive patients with grade II-III haemorrhoids were treated with laser haemorrhoidoplasty. Short-term follow-up was assessed on days 1, 30 and 60 and long-term follow-up was at 5 years (haemorrhoidal stage reduction, pain, patient satisfaction, symptom improvement, incapacity for work, continence, complications, recurrence).

RESULTS

Short-term follow-up was achieved for all patients and long-term follow-up for 44/50 patients (88%). At short-term follow-up, haemorrhoidal stage reduction was documented in 49 (98%) patients. Complete or good symptom improvement was reported by 36/50 (72%) and 10/50 patients (20%) at 60 days. Postoperative complications occurred in 9/50 patients (18%) with three Clavien-Dindo grade IIIb complications (two fistulas, one incontinence), one grade IIIa (perianal thrombosis) and five grade I (one perianal thrombosis, two perianal eczema, one local bleeding, one anal fissure). Postoperative pain was low (visual analogue scale 0-1) at day 1 in 37/50 (74%), at day 30 in 47/50 (94%) and at day 60 in 50/50 patients (100%). After a mean follow-up of 5.4 years (SD 5.4 months) the recurrence rate was 34% (15/44 patients) with a median time to recurrence of 21 months (range 0.2-6 years).

CONCLUSION

Although laser haemorrhoidoplasty achieves a high short-term success rate with respect to stage reduction and symptom improvement, it is associated with a high rate of minor postoperative complications and long-term recurrence. Therefore, laser haemorrhoidoplasty should be used with caution.

Surgical management of haemorrhoids: an Italian survey of over 32 000 patients over 17 years

AIM

The management of haemorrhoids has changed significantly in the last two decades as a result of new insights into their pathophysiology and the availability of new surgical devices. The aim of this survey was to evaluate changes in the management of haemorrhoids in Italy over the last 17 years.

METHOD

An electronic database which recorded details of management relating to the severity of haemorrhoids between 2000 and 2016 was obtained from 18 of 34 colorectal surgeons who were invited to participate.

RESULTS

A total of 32 458 patients were treated for haemorrhoids by 18 expert coloproctologists during a 17-year period. Patients were classified as Grade II (7542, 23.2%), Grade III(15 360, 47.3%) and Grade IV (9556, 29.4%). Grade II haemorrhoids were treated with rubber band ligation in over 90% of the cases, and patients with Grade IV had a Milligan-Morgan (MM) haemorrhoidectomy in over 90% of the cases. In Grade III, the use of stapled haemorrhoidopexy progressively decreased from 30% to 35% (between 2000 and 2007) to 5% of the cases. Meanwhile, commencing from 2006 the use of Doppler-guided haemorrhoid artery ligation (DGHAL) with mucopexy increased progressively from 6% to 24%. Over the years, the percentage of MM haemorrhoidectomy remained consistent at between 65% and 70% of the cases.

CONCLUSION

Relevant changes in the surgical choice of haemorrhoid treatment have occurred in Italy over the last 17 years. MM haemorrhoidectomy remains the most frequently performed procedure for Grade III haemorrhoids. Stapled haemorrhoidopexy has become much less popular in contrast to DGHAL with mucopexy which is being performed much more frequently.

Doppler-guided hemorrhoidal dearterialization with laser (HeLP): a prospective analysis of data from a multicenter trial

BACKGROUND

Doppler-guided hemorrhoidal laser procedure (HeLP) is a new minimally invasive technique to treat symptomatic hemorrhoids. The aim of this multicenter study was to prospectively assess clinical results and patients' satisfaction in patients treated with HeLP.

METHODS

Indications for HeLP included patients with symptomatic hemorrhoids resistant to medical therapy, with low-grade prolapse. Clinical efficacy was evaluated assessing resolution of symptoms and patient satisfaction. Frequency of bleeding and frequency of acute hemorrhoid-related symptoms were given a score of 0 to 4 (where 4 = more than 3 episodes/week) and 0 to 3 (where 3 = more than 5 episodes/year), respectively. Quality of life, pain at rest, and pain with evacuation were scored using a visual analogue scale (VAS) of 0 to 10. Intra- and postoperative complications were recorded. Potential predictive factors for failure were assessed.

RESULTS

Two hundred and eighty-four patients (183 males, 101 females) with a mean age of 47.5 years were included in the study. At 6-month follow-up, symptoms had completely resolved in 257/284 (90.5%) and 275/284 (96.8%) patients were satisfied with the results. An analysis of a subgroup of 144 patients followed up for a minimum of 12 months revealed a resolution of symptoms in 130/144 (90.3%) and satisfaction in 139/144 (96.5%). There was a statistically significant improvement of the bleeding score (from 2.4 ± 1.07 to 0.36 ± 0.49; p < 0.0001), acute symptoms score (from 2.03 ± 0.16 to 0.61 ± 0.59; p < 0.0001), quality of life (from 4.63 ± 1.32 to 8.96 ± 1.35; p < 0.0001), pain at rest (from 3.0 ± 2.05 to 1.1 ± 0.99; p < 0.0006), and pain with evacuation (from 4.8 ± 1.22 to 1.7 ± 1.15; p < 0.0001). No significant changes in continence and constipation were observed. Univariate analysis failed to show factors significantly associated with failure.

CONCLUSIONS

The HeLP procedure seems to be safe and effective in patients with symptomatic hemorrhoids. It is simple, minimally invasive, and relatively pain free. It can be performed in an ambulatory setting without anesthesia, and it achieves high patient satisfaction. It may, therefore, be considered a "first-line treatment" in all patients without significant hemorrhoidal prolapse in whom medical therapy has failed.

Modified Doppler-guided laser procedure for the treatment of second- and third-degree hemorrhoids

BACKGROUND

Hemorrhoids are a common anorectal condition with a major medical and socioeconomic impact. Owing to the high incidence of symptomatic hemorrhoids in the adult population together with the risk of complications of traditional surgery, researchers are seeking less invasive methods of hemorrhoidal treatment.The aim of this study was to present our experience with the mini-invasive Doppler guided hemorrhoidal laser procedure (HeLP) in symptomatic 2nd and 3rd degree hemorrhoids with absent or minimal mucosal prolapse.

METHODS

The cohort included 62 patients with symptomatic hemorrhoids who underwent the HeLP at a tertiary medical center in 2014-2016. Data were collected on clinical and perioperative characteristics and outcome. Findings were compared between patients with second- and third-degree hemorrhoids.

RESULTS

The cohort included 41 male and 21 female patients of mean age 41.5 years. Fifty-one had bleeding and 11 had hemorrhoidal syndrome. Mean operative time was 16.6 ± 3.7 minutes. A total of 8-12 arterial branches were treated. Patients were discharged home within a mean of 91.95 ± 20.48 minutes and allowed to resume normal activities. Compared to patients with second-degree hemorrhoids, patients with third-degree hemorrhoids had a significantly higher rate of recto-anal repair (18.2% vs 0, p < 0.05), intraoperative bleeding (11.3% vs 5%, p < 0.05), and thrombus formation in the hemorrhoids (11.3 % vs 0, p < 0.01). At the six-month follow-up, no complications were reported, and there was significant improvement in symptoms.Using the visual analog scale, no pain was reported by 82.3% of patients at one week after surgery and 95.2% of patients at one month after surgery.

CONCLUSION

Patients with hemorrhoids treated with Doppler-guided laser had an excellent outcome in terms of resolution of symptoms and postoperative pain. Only Minor short-term complications were noted. Doppler-guided laser seems to be an effective and painless technique for the treatment of symptomatic second- to third grade hemorrhoids with minimal mucosal prolapse.

Transanal Hemorrhoidal Dearterialization Versus Stapled Hemorrhoidopexy: Long-Term Follow-up of a Prospective Randomized Study

Aim. This study aims to compare the early and late outcomes of transanal hemorrhoidal dearterialization (THD) versus stapled hemorrhoidopexy (SH) for the treatment of hemorrhoidal disease. Methods. From January 2013 to December 2014, 100 patients—50 patients on each arm—were randomly allocated to THD or SH groups. The inclusion criteria were grade III and IV hemorrhoids diagnosed by clinical examination and proctoscopy. The primary outcome was to compare the recurrence rate with a minimum follow-up of 2 years, and the secondary outcome was to compare complications rate, time to return to work postsurgery, procedure length, and patient’s satisfaction between the 2 techniques. Results. The mean follow-up period was 33.7 ± 7.6. The recurrence rate was 4% in the SH group and 16% in the THD group ( P = .04). There was no difference in the intraoperative and postoperative complications rate; the pain score was significantly higher in the THD group. The mean operative time was significantly shorter in the SH group compared with the THD group. Patients in the THD group returned to work or routine activities significantly later compared with patients in the SH group. The overall satisfaction rate was also higher in the SH group. Conclusion. Both procedures are simple and easy to perform for the treatment of grade III and IV hemorrhoids. SH showed better results in terms of lower rate of recurrence, lower postoperative pain, quicker return to work, and higher patient satisfaction.

A Randomized Controlled Trial Comparing Laser Intra-Hemorrhoidal Coagulation and Milligan-Morgan Hemorrhoidectomy

PURPOSE

To compare laser intra-hemorrhoidal coagulation with Milligan-Morgan (MM) hemorrhoidectomy.

METHOD

Patients with symptomatic grade II or III internal hemorrhoids according to the Goligher's classification (refractory to medical treatment) were enrolled in this double-blinded randomized controlled trial study. In the laser group, hemorrhoidal columns were coagulated using a 980-nanometer (nm) radial laser emitting fiber (three, 15-W pulses of 1.2 s each, with 0.6-s intervals). Operative time, postoperative pain and complications, and recovery or resolution of symptoms were measured. Patients were followed up for at least one year for evaluating healing, resolution of symptoms, and late complications.

RESULTS

Postoperative pain scores (at 12, 18, and 24 hr after surgery) were significantly lower in the laser group compared with the MM group (p <.01). The operative time and intra-operative blood loss were more in the MM group (p <.001). The administration of analgesics was significantly reduced in the laser group (p <.05). Two patients in the laser group were presented with thrombosis of external hemorrhoid 7-10 days after the procedure, which was resolved with medical treatment, but no patients in the MM group developed hemorrhoidal thrombosis (p >.05). One-year follow-up showed comparable results in terms of the resolution of symptoms and sustainable cure.

CONCLUSIONS

Intra-hemorrhoidal coagulation with 980-nm diode laser reduces postoperative pain, intra-operative bleeding, and administered analgesics with a comparable resolution rate of hemorrhoid symptoms. However, for the patients who experience complications, such as hemorrhoidal thrombosis, the overall pain may be equivalent to or even worse than conventional hemorrhoidectomy.

Hemorrhoid laser procedure for second- and third-degree hemorrhoids: results from a multicenter prospective study

BACKGROUND

The aim of our study was to assess the outcome of hemorrhoidal dearterialization, achieved by a dedicated laser energy device.

METHODS

From November 2012 to December 2014, 51 patients with second- or third-degree hemorrhoids were studied. The primary end point was a reduction in the bleeding rate; secondary end points were: postoperative complications, reduction in pain and prolapse, resolution of symptoms, and degree of patient's perception of improvement. The procedure was carried out as 1-day surgery. A diode laser device was employed to seal the terminal branches of the hemorrhoidal arteries, detected by a Doppler-equipped proctoscope. Follow-up was scheduled at 1 and 4 weeks, 3, 12, and 24 months. The rate and degree of symptoms was assessed with a four-point verbal rating scale. The rate of subjective symptomatic improvement was also evaluated with the Patient Global Improvement (PGI) Scale.

RESULTS

Mean bleeding and pain scores at baseline were 2 and 0.57. All the patients were discharged on the day of surgery. Postoperative complications were bleeding (n = 4) and external hemorrhoidal thrombosis (n = 4). Mean bleeding and pain scores at 3, 12, and 24 months were significatively reduced. After 24 months, complete resolution of bleeding was observed in 28/29 patients (96.7 %), resolution of pain in all patients, and resolution of the mucosal prolapse in 15/18 patients (76.9 %). At 12-month follow-up, 86.3 % of patients reported improvement with the PGI Scale.

CONCLUSIONS

The hemorrhoid laser procedure was effective in improving bleeding and pain symptoms in patients with grade II and III hemorrhoids.

Advantages and limits of hemorrhoidal dearterialization in the treatment of symptomatic hemorrhoids

In the last two decades, hemorrhoidal dearterialization has become universally accepted as a treatment option for symptomatic hemorrhoids. The rationale for this procedure is based on the assumption that arterial blood overflow is mainly responsible for dilatation of the hemorrhoidal plexus due to the absence of capillary interposition between the arterial and venous systems within the anal canal. Dearterialization, with either suture ligation (Doppler-guided hemorrhoid artery ligation/transanal hemorrhoidal dearterialization) or laser (hemorrhoidal laser procedure), may be successfully performed alone or with mucopexy. Although the added value of Doppler-guidance in association with dearterialization has recently been challenged, this imaging method still plays an important role in localizing hemorrhoidal arteries and, therefore, minimizing the effect of anatomic variation among patients. However, it is important to employ the correct Doppler transducer. Some Doppler transducers may not easily detect superficial arteries due to inadequate frequency settings. All techniques of dearterialization have the advantage of preserving the anatomy and physiology of the anal canal, when compared to other surgical treatments for hemorrhoids. This advantage cannot be underestimated as impaired anal function, including fecal incontinence and other defecation disorders, may occur following surgical treatment for hemorrhoids. Furthermore, this potentially devastating problem can occur in patients of all ages, including younger patients.

Ambulatory haemorrhoidal surgery: systematic literature review and qualitative analysis

PURPOSE

The aims of this study are to review the advantages and drawbacks of the ambulatory management of patients scheduled for haemorrhoidal surgery and to highlight the reasons for unplanned hospital admission and suggest preventive strategies.

METHODS

We conducted a systematic review of the literature from January 1999 to January 2013 using MEDLINE and EMBASE databases. Manuscripts were specifically analysed for failure and side effects of haemorrhoidal surgery in ambulatory settings.

RESULTS

Fifty relevant studies (6082 patients) were retrieved from the literature review. The rate of ambulatory management failure ranged between 0 and 61%. The main reasons for failure were urinary retention, postoperative haemorrhage and unsatisfactory pain control. Spinal anaesthesia was associated with the highest rates of urinary retention. Doppler-guided haemorrhoidal artery ligation has less frequent side effects susceptible to impair ambulatory management than haemorrhoidectomy and stapled haemorrhoidopexy. However, the fact that haemorrhoidopexy is less painful than haemorrhoidectomy may allow ambulatory management.

CONCLUSION

Day-case haemorrhoidal surgery can be performed whatever the surgical procedure. Postoperative pain deserves special prevention measures after haemorrhoidectomy, especially by using perineal block or infiltrations. Urinary retention is a common issue that can be responsible for failure; it requires a preventive strategy including short duration spinal anaesthesia. Doppler-guided haemorrhoidal artery ligation is easy to perform in outpatients but deserves more complete evaluation in this setting.

Recent advances in the management of hemorrhoids

Hemorrhoids are considered one of the most common anorectal diseases with a prevalence of 4.4% up to 36.4% of the general population, and a peak incidence between 45 and 65 years. Hemorrhoidal disease presents with a prolapsed lump, painless bleeding, discomfort, discharge, hygiene problems, soiling, and pruritus. Sliding anal canal lining theory is the most accepted theory as a cause of hemorrhoidal disease; however, it is also associated with hyper-vascularity, and, recently, with several enzymes or mediators involved in the disintegration of the tissues supporting the anal cushions, such as matrix metalloproteinase. A comprehensive search in published English-language literature till 2013 involving hemorrhoids was performed to construct this review article, which discusses advances in the management of hemorrhoids. This includes conservative treatment (life style modification, oral medications, and topical treatment), office procedures (rubber band ligation, injection sclerotherapy, infrared and radiofrequency coagulation, bipolar diathermy and direct-current electrotherapy, cryosurgery, and laser therapy), as well as surgical procedures including diathermy hemorrhoidectomy, LigaSure hemorrhoidectomy, Harmonic scalpel hemorrhoidectomy, hemorrhoidal artery ligation, stapled hemorrhoidopexy (SH), and double SH. Results, merits and demerits of the different modalities of treatment of hemorrhoids are presented, in addition to the cost of the recent innovations.

Conservative and surgical treatment of haemorrhoids

The management of haemorrhoids has evolved rapidly during the past few decades. Several new treatments have been proposed with the aim of reducing patients' postoperative pain, time to return to normal life, risk of early and late complications, and recurrence rate. Although conservative treatment based on dietary and lifestyle changes can help the majority of patients, and rubber band ligation and phlebotonic drugs can effectively treat grade I and II haemorrhoids, surgery is required for the most advanced stages. Milligan-Morgan haemorrhoidectomy is considered to be the gold-standard approach for grade IV haemorrhoids. An increasing number of minimally invasive treatment options, including mucopexy with or without mucosal resection and haemorrhoid artery ligation, have now been proposed for the management of grade III haemorrhoids. These approaches aim to correct the underlying pathophysiological mechanisms involved in the aetiology of haemorrhoids. An increased risk of recurrence is the price to pay for these minimally invasive and less painful treatments, but the sparing of the sensitive anoderm and a rapid return to normal life without pain are greatly appreciated by patients. An algorithm for the management of haemorrhoids using evidence-based medicine is also presented here.

New bipolar tissue ligator combines constant tissue compression and temperature guidance: histologic study and implications for treatment of hemorrhoids

Background

Several minimally invasive technologies are available to treat common soft tissue lesions including symptomatic hemorrhoids. The use of energy to deliver heat and coagulate target lesions is commonly practiced. This study compares the histologic effects produced on intestinal tissues by two energy-based systems which employ different approaches of heat delivery.

Methods

Two heat delivery systems were evaluated in vivo in a single porcine subject: infrared coagulator and bipolar tissue ligator utilizing constant tissue compression and temperature guidance. Eighteen treatment sites divided into three groups of six were assessed. Treatment site temperature was measured and the effects of thermal treatment in the mucosa, submucosa, submucosal vessels, and muscularis layer were scored. Lateral thermal spread beyond the energy application site was also assessed.

Results

Treatment site temperatures were much lower in the bipolar ligator group than in the infrared coagulator group. The mucosal and submucosal tissue changes observed in tissues treated with infrared energy and bipolar energy at 55°C were similar. Both the mucosal and submucosal tissue changes with bipolar energy at 50°C were significantly less.

Conclusion

Both devices achieved similar histologic results. However, the unique design of the bipolar ligator, which allows consistent capture, constant compression, and temperature monitoring of target tissue, accomplished the desired histologic changes with less muscular damage at much lower temperatures than the infrared coagulator. The use of bipolar ligation could offer clinical advantages such as reduced patient pain and a minimized chance of heat-related collateral tissue damage.

[Consensus statement haemorrhoidal disease]

Haemorrhoidal disease belongs to the most common benign disorders in the lower gastrointestinal tract. Treatment options comprise conservative as well as surgical therapy still being applied arbitrarily in accordance with the surgeon's expertise. The aim of this consensus statement was therefore to assess a stage-dependent approach for treatment of haemorrhoidal disease to derive evidence-based recommendations for clinical routine. The most common methods are discussed with respect of haemorrhoidal disease in extraordinary conditions like pregnancy or inflammatory bowel disease and recurrent haemorrhoids. Tailored haemorrhoidectomy is preferable for individualized treatment with regard to the shortcomings of the traditional Goligher classification in solitary or circular haemorrhoidal prolapses.

Doppler-guided hemorrhoidal artery ligation does not offer any advantage over suture ligation of grade 3 symptomatic hemorrhoids

BACKGROUND

Doppler-guided ligation of hemorrhoidal vessels is being proposed as a treatment of grade 2 and 3 hemorrhoids. Many researchers are coupling this procedure with mucopexy or lifting of hemorrhoids to control the prolapse more effectively. The present study was conducted in patients with 3rd-degree hemorrhoids to determine the usefulness of Doppler-guided hemorrhoidal artery ligation compared to mucopexy of prolapsing hemorrhoids and to compare it with mere mucopexy of the hemorrhoids.

MATERIALS AND METHODS

A double-blind, randomized controlled study was conducted on 48 consecutive patients with grade III hemorrhoids requiring surgery. The patients were randomized into two groups. Half of them were treated with ligation and mucopexy [SL], while the remaining patients underwent a Doppler-guided hemorrhoidal artery ligation followed by ligation and mucopexy [DSL]. The patients were examined by a blinded independent observer at 2, 4, and 6 weeks and at the end of 1 year after the operation to evaluate postoperative pain scores, amount of analgesics consumed, and complications encountered. The observer also assessed recurrence of hemorrhoids after 1 year.

RESULTS

Operative time was significantly longer in the DSL group (31 min vs. 9 min P < 0.003). The postoperative pain score was significantly higher in the Doppler group [4.4 vs. 2.2, P < 0.002 (visual analogue scale)]. The mean total analgesic dose and duration of pain control using analgesics were greater and longer for the Doppler group than for the SL group (17 vs. 11 tablets, and 13 days vs. 9 days, respectively; P < 0. 01). Complications were similar in both the groups. At 1-year follow-up, the recurrence of hemorrhoids was not statistically significant in either group (4 patients in SL group and 3 patients in DSL group; P < 0.93).

CONCLUSIONS

Suture ligation of hemorrhoids is a simple, cost-effective, and convenient modality for treating grade 3 hemorrhoids. Doppler assistance in ligating the hemorrhoidal vessels prior to hemorrhoidal mucopexy offers no advantage and is a time-consuming procedure.
