RESUMO

BACKGROUND: Laser Hemorrhoidoplasty (LHP) is a minimally invasive surgical option for the management of hemorrhoidal disease that has been increasingly adopted by surgeons over the last decade. Two wavelengths; 980 nm and 1470 nm have been employed in LHP. However, no data exist comparing the effects of these two wavelengths for this indication. This systematic review investigates both wavelengths for the management of hemorrhoids via the LHP procedure. METHODS: This systematic analysis and meta-analysis was performed following the PICOS and PRISMA guidelines. A systematic research of MEDLINE, Scopus, Clinicaltrials.gov, Embase, Cochrane Central Register of Controlled Trials, CENTRAL and Google Scholar databases from inception until March 2024 was performed. RESULTS: Overall, 19 studies including seven randomized control trials (RCT) and 12 non-randomized control trials with a total of 2492 patients were included in this systematic review and meta-analysis. The duration of LHP with both wavelengths was significantly shorter compared to open hemorrhoidectomy, postoperative pain and the rate of postoperative complications were significantly lower following LHP. There was no statistically significant difference in the rate of recurrence between LHP with the 980-nm wavelength and open hemorrhoidectomy. However, LHP with 1470-nm wavelength resulted in significantly higher recurrence rate compared to hemorrhoidectomy. CONCLUSION: Although no direct studies have compared the two wavelengths used in LHP, the outcomes of LHP seem to be independent of the wavelength used. Both wavelengths, when correctly used provide similar results, which are mostly better compared to open hemorrhoidectomy in terms of postoperative complications and postoperative pain, but not in terms of recurrence, where at least for the 1470-nm wavelength, LHP seems to show a higher recurrence rate when compared to open hemorrhoidectomy. Although a direct comparison of both wavelengths was not possible, technical issues regarding number of shots and energy per pile represent relevant parameters for recurrence after LHP.

RESUMO

PURPOSE: As a minimally invasive procedure, laser hemorrhoidoplasty (LHP) can not only relieve the symptoms of hemorrhoids, but also protect the anal cushion structure. This study aimed to investigate the clinical efficacy of LHP in the treatment of grade II hemorrhoids. METHODS: A total of 70 patients with grade II hemorrhoids were randomly assigned to receive LHP or Rubber Band Ligation (RBL) (n = 35 per group) in 2019 from a single center. The postoperative pain, bleeding, feeling of anal distension(local falling, swelling, foreign body sensation, stool) and postoperative recurrence rate were compared between the two groups. RESULTS: The postoperative pain, bleeding, and feeling of anal distension in the LHP group were improved significantly as compared with the RBL group within 2 weeks after surgery (P < 0.01). Both methods can relieve the symptoms of grade II hemorrhoids. There was no difference in the recurrence rate between the two groups at 1 year after surgery (P > 0.05). The patients in LHP group took less time to return to normal activities (P < 0.001). CONCLUSIONS: As a minimally invasive treatment, LHP is easy and not traumatic and results in mild postoperative pain and few complications. It is an ideal choice for grade II hemorrhoids.

RESUMO

BACKGROUND: Laser hemorrhoidoplasty has demonstrated significant therapeutic effectiveness. To diminish postoperative bleeding and enhance overall outcomes, we have additionally adopted suture ligating the feeding vessels. This study aimed to understand the treatment outcomes and any associated complications. METHODS: This study comprised patients with symptomatic grade II-III hemorrhoids who underwent laser hemorrhoidoplasty with feeding vessel suture ligation and Milligan-Morgan hemorrhoidectomy between 1 September 2020, and 31 August 2022. Surgical-related details, postoperative pain, discomfort after discharge, hemorrhoid recurrence, and any complications were collected from inpatient records, outpatient follow-ups, and telephone interviews. Initially, we will analyze the distinctions between the laser group and the traditional group, followed by an investigation into complications and satisfaction within the laser surgery subgroup. RESULTS: The study included 323 patients, with 173 undergoing laser hemorrhoidoplasty (LHP) and 150 undergoing Milligan-Morgan hemorrhoidectomy. Regarding pain assessment, the LHP group exhibited superior performance compared to traditional surgery at postoperative 4 h, before discharge, and during the first and second outpatient visits, with statistically significant differences. Additionally, the LHP group had a lower rate of urinary retention and experienced significantly less pain, with statistically significant differences. CONCLUSIONS: Laser hemorrhoidoplasty with feeding vessels suture ligation has been shown to reduce postoperative pain and appears to be a promising minimally invasive treatment option for symptomatic grade II and III hemorrhoids.

RESUMO

This case report outlines the intricate management of rectal perforation following laser hemorrhoidoplasty in a 31-year-old female, leading to an acute abdomen, sepsis, and multiorgan failure. Urgent laparoscopic exploration and the establishment of a double-loop colostomy were undertaken, marking the beginning of a complex course characterized by relapsed pelvic sepsis. Laser hemorrhoidoplasty has gained widespread acceptance for its minimally invasive approach in treating hemorrhoids. Remarkably, to our knowledge, the case we present is the first major complication reported after laser hemorrhoidoplasty, likely attributed to collateral thermic and mechanical tissue damage.

RESUMO

PURPOSE: Hemorrhoidal disease (HD) is a common condition, and several surgical techniques have been proposed to date without being able to achieve definitive consensus on their use and indications. Laser hemorrhoidoplasty (LHP) is a minimally invasive procedure for HD treatment determining the shrinkage of the hemorrhoidal piles by diode laser limiting the postoperative discomfort and pain. The aim of the current study was to evaluate the postoperative outcomes of HD patients undergoing LHP vs conventional Milligan-Morgan hemorrhoidectomy (MM). METHOD: Postoperative pain, wound care management, symptoms' resolution, patients' quality of life, and length of return to daily activity of grade III symptomatic HD patients undergoing LHP vs MM were retrospectively evaluated. The patients were followed-up for recurrence of prolapsed hemorrhoid or symptoms. RESULT: From January 2018 to December 2019, 93 patients received conventional Milligan Morgan as control group and 81 patients received laser hemorrhoidoplasty treatment using a 1470-nm diode laser. No significant intraoperative complications occurred in both groups. Laser hemorrhoidoplasty patients experienced lower postoperative pain score (p < 0.0001) and smoother wound management. After 25 ± 8 months follow-up, the recurrence of symptoms occurred in 8.1% after Milligan-Morgan and 21.6% after laser hemorrhoidoplasty (p < 0.05) with a similar Rorvik score (7.8 ± 2.6 in LHP group vs 7.6 ± 1.9 in MM group, p = 0.12). CONCLUSION: LHP demonstrated high efficacy in selected HD patients guaranteeing lower postoperative pain, easier wound care, higher rate of symptoms resolution, and greater patient appreciation compared to MM, even though it had a higher recurrence rate. Larger comparative studies are needed to address this issue.

RESUMO

INTRODUCTION: The effectiveness of hemorrhoidal artery ligation supplementation in reducing the incidence of post laser hemorrhoidoplasty bleeding has not been investigated. METHODS: This was a double-blind, randomized controlled trial comparing post-operative bleeding incidence in patients undergoing laser hemorrhoidoplasty (LHP) only versus LHP with hemorrhoidal artery ligation (HAL). Outcome measures included post-operative bleeding and its severity (i.e. verbal rating scale and Clavien-Dindo classification), presence of perianal swelling and pain score (visual analog score) at 1-day, 1-week and 6-weeks post-operatively. Statistical tests were performed and a value of P < 0.05 was considered significant. RESULTS: Seventy-six patients were randomized. There was no difference in median operating time. The bleeding incidence was highest at 1-week post-operatively (17.1%), and decreased to 1.3% at 6-weeks. There was no significant difference in bleeding incidence between both groups at any of the measured timepoints (P > 0.05). Severity of bleeding and incidence of post-operative perianal swelling were similar in both groups (P > 0.05). There was no difference in median pain scores. CONCLUSION: Supplementation of HAL to LHP does not reduce the post-operative bleeding incidence. LHP is sufficient as a stand-alone procedure for treating haemorrhoids. TRIAL REGISTRATION: National Registration Number is NMRR-15-1112-24065 (IIR). The trial start date was 1st January 2015 with the ClinicalTrials.gov identifier and registration number as NCT04667169.

RESUMO

PURPOSE: To compare the results of laser hemorrhoidoplasty (LHP), excisional hemorrhoidectomy (EH), and sutured mucopexy (MP). METHODS: A randomized, parallel-group, double-blinded, single-center prospective study. PATIENTS: Symptomatic 2nd- or 3rd-degree hemorrhoids patients. INTERVENTIONS: Computer randomization sequence, patient blinding, operating surgeon blinding, and surgeon-evaluator blinding. LHP was performed using a 1470 nm diode laser. Up to 250 J of energy delivered per 1 hemorrhoid. The procedure was performed circumferentially. MP ligations were placed in the area of visible hemorrhoidal tissue. Standard EH was performed up to the level of the hemorrhoidal pedicle. Follow-up at 1 and 6 weeks and 1 year. OUTCOME MEASURES: Recurrence of symptoms requiring treatment, intensity, and duration of pain after the operation, patients' quality of life, fecal incontinence, and patients' evaluation of treatment. RESULTS: A total of 121 patients. Groups were even preoperatively. LHP took 15 min (SD 5.6), MP took 16 min (SD 5.58), and EH took 29 min (SD 10.3). Recurrence requiring treatment rate was 0% after EH, 10% after LHP, and 22% after MP, p = 0.004. LHP and MP were less painful than EH, p < 0.001. Patients after LHP returned to regular activity after 15 days, after MP after 22 days, and after EH after 30 days, p < 0.001. SF-36 scores were better after EH. Symptoms of fecal incontinence improved in all the groups. Patients evaluate LHP better than EH and MP. LIMITATIONS: Single-center study. CONCLUSIONS: Laser hemorrhoidoplasty is a safe, minimally invasive option for hemorrhoids, more effective than MP and less effective than EH. Patients evaluate this technique better than the other two.

RESUMO

Conventional hemorrhoidectomy is the mainstay of treatment for symptomatic haemorrhoids, but reported postoperative complications remains the main concern. On the contrary, with its minimally invasive nature, laser hemorrhoidoplasty showed the potential to reduce postoperative complications and discomfort. Therefore, we performed a systemic review and meta-analysis to evaluate the postoperative outcome of laser hemorrhoidoplasty compared to conventional hemorrhoidectomies, including Milligan-Morgan and Ferguson techniques. Of all studies from PubMed, EMBASE, Cochrane database, and Google Scholar, we included 17 trials with 1196 patients, of whom 596 (49.8 %) underwent laser hemorrhoidoplasty and 600 (50.2 %) underwent conventional hemorrhoidectomy. The primary outcomes were operative blood loss and postoperative haemorrhage, and the secondary outcomes were the operative time, postoperative pain score, complications, and haemorrhoid recurrence. In this study, we found that laser hemorrhoidoplasty showed benefits in operative blood loss (weighted mean difference [WMD]: -16.43 ml, 95 % confidence interval [CI]: -23.82 to -9.04), postoperative hemorrhage/bleeding (odds ratio [OR]: 0.16, 95 % CI: 0.10 to 0.28), operative time (WMD: -12.42 min, 95 % CI: -14.56 to -10.28), postoperative pain score on day 1 (WMD: -2.50, 95 % CI: -3.13 to -1.88), and anal stenosis (OR: 0.14, 95 % CI: 0.03 to 0.65) in comparison with conventional hemorrhoidectomy. However, incidence of fecal/flatus incontinence, urinary retention and hemorrhoid recurrence were not significantly different between the 2 groups. Consistent results were found in 5 subgroup analyses, including studies with low risk of bias, studies using 1470 nm laser, and studies using 980 nm laser, studies conducted in Asia, and studies conducted in Europe and America.

RESUMO

The aim of these evidence-based guidelines is to present a consensus position from members of the Italian Unitary Society of Colon-Proctology (Società Italiana Unitaria di Colon-Proctologia, SIUCP) on the diagnosis and management of hemorrhoidal disease, with the goal of guiding physicians in the choice of the best treatment option. A panel of experts was charged by the Board of the SIUCP to develop key questions on the main topics related to the management of hemorrhoidal disease and to perform an accurate and comprehensive literature search on each topic, in order to provide evidence-based answers to the questions and to summarize them in statements. All the clinical questions were discussed by the expert panel in multiple rounds through the Delphi approach and, for each statement, a consensus among the experts was reached. The questions were created according to PICO (patients, intervention, comparison, and outcomes) criteria, and the statements were developed adopting the GRADE (Grading of Recommendations, Assessment, Development, and Evaluations) methodology. In cases of grade 1 hemorrhoidal prolapse, outpatient procedures including hemorrhoidal laser procedure and sclerotherapy may be considered the preferred surgical options. For grade 2 prolapse, nonexcisional procedures including outpatient treatments, hemorrhoidal artery ligation and mucopexy, laser hemorrhoidoplasty, the Rafaelo procedure, and stapled hemorrhoidopexy may represent the first-line treatment options, whereas excisional surgery may be considered in selected cases. In cases of grades 3 and 4, stapled hemorrhoidopexy and hemorrhoidectomy may represent the most effective procedures, even if, in the expert panel opinion, stapled hemorrhoidopexy represents the gold-standard treatment for grade 3 hemorrhoidal prolapse.

RESUMO

Background and objective Minimally invasive techniques in the surgical treatment of hemorrhoids have been gaining in popularity. Laser hemorrhoidoplasty (LHP) and LigaSure™ (LigH; Medtronic, Dublin, Ireland) hemorrhoidectomy methods are the most recent innovative methods that are increasingly used. In this study, we aimed to compare the effectiveness of these two innovative techniques. Methods The data of patients who underwent LHP or LigH for grade III hemorrhoidal disease at our clinic between January 2022 and June 2023 were retrospectively analyzed. Postoperative pain levels, time to return to work or daily activities, complication rates, and recurrence rates of the treated patients were recorded. Results A total of 100 patients were included in the study. Of these, 48 patients had LHP surgery and 52 had LigH surgery. The demographic characteristics of both groups were similar. The mean operation time was statistically significantly shorter in the LHP group (p<0.001). The visual analog scale (VAS) scores on postoperative days one and seven were lower in favor of the LHP (2.4 ± 0.7 and 1.2 ± 0.9 vs. 6.2 ± 1.5 and 3.8 ± 1.3, respectively; p< 0.001). The median time to return to daily activity was 2.3 (range: one to three) days in the LHP group and 4.6 (range: 3-11) days in the LigH group (p<0.001). Recurrence was observed in 11 (22%) patients in the LHP group and in three (6%) patients in the LigH group (p<0.001). Conclusion Based on our findings, LHP is an effective procedure for the surgical treatment of hemorrhoidal disease as it is associated with less morbidity, less pain, early return to work, and acceptable recurrence rates.

RESUMO

INTRODUCTION: Minimally invasive techniques still continue to maintain their popularity in hemorrhoidal disease. In this study, we aimed to present the symptomatic recovery and recurrence rates, post-operative pain levels, and complication rates of patients treated with the laser hemorrhoidoplasty (LHP) method in our clinic. METHODS: The data of patients who underwent LHP due to Grades 2, 3, and 4 internal hemorrhoidal disease in our clinic were reviewed retrospectively. The patients enrolled in the study were followed for at least 6 months (6 months, 1 year, and 2 years) and their results were analyzed. RESULTS: A total of 103 patients were included in the study. Seventy-five (72.8%) of them were male and the mean age was 41.6 ± 13.6 years. The mean operation time was 17.9 ± 5.2 min and minor complications developed in 3 (2.9%) patients postoperatively. Mean time to return to normal daily life was 2.17 (1-11) days. Recurrence developed in 16 (17.6%) patients with Grades 2 and 3 disease and in 6 (50%) of 12 patients with Grade 4 disease (p = 0.019). CONCLUSION: LHP is a popular procedure which is effective in selected patient groups with acceptable recurrence rates.

RESUMO

Hemorrhoidal disease (HD) treatment still remains controversial. In fact, despite many surgical progresses, postoperative pain, and discomfort remain the major weaknesses. Laser hemorrhoidoplasty (LHP) is a minimal invasive procedure for HD treatment determining the shrinkage of the hemorrhoidal piles by diode laser. The aim of the current study is to analyze the feasibility and efficacy of LHP in patients with II-III degrees hemorrhoids. Consecutive patients with II-III degree hemorrhoids were enrolled in the study and underwent an LHP treatment using a 1470-nm diode laser. Operative time, postoperative pain and complications, resolution of symptoms, and length of return to daily activity were prospectively evaluated. Recurrence of prolapsed hemorrhoid or symptoms at a minimum follow-up of 6 months was evaluated. Fifty patients (28 males and 22 females) were enrolled in the study. No significant intraoperative complications occurred. Postoperative pain score (at 12, 18, and 24 h postoperatively), evaluated through visual analogue scale, was extremely low (mean value 2). No postoperative spontaneous bleeding occurred. The 100% of our population came back to daily activity 2 days after surgery. At a mean follow-up period of 8.6 months, we reported a recurrence rate of 0%. LHP demonstrated a large efficacy in selected patients. The greatest strength points were low postoperative pain, the presence of slightly significant peri-anal wounds, no special anal hygienic measures and low surgical time. Thus, resulting in a negligible postoperative discomfort, LHP could be considered a painless and minimal invasive technique in the treatment of HD.

RESUMO

BACKGROUND: Laser hemorrhoidoplasty (LHP) is a new technique for treatment of hemorrhoids. The exact extent of coagulation is not visible at the time of the procedure. There currently is no experimental or clinical data on the subject. OBJECTIVE: To evaluate the length of coagulation defect according to power and activation time of 1470nm diode laser on the perianal tissue model. METHODS: Fresh anorectal tissue of twenty-four pigs was used to produce 54 experimental samples. Each sample was randomly assigned to the laser power of 6, 8 and 10 W and 1, 2 or 3-second pulses. The procedure was performed using Biolitec Ceralas © diode laser with 1.85 mm optical fiber. The fiber was inserted in a manner, similar to intrahemorrhoidal laser application. Samples were evaluated using low-power and high-power light microscopy by a single pathologist. The length of tissue injury was measured on high-magnification microscopy. RESULTS: The longest tissue injury (mean 3.93 mm) was caused by the longest laser exposure time (3 sec) with no significant difference between laser power used. CONCLUSIONS: 8 W 3-second application of the 1470nm diode laser results in coagulation area approximately 4 mm, and further coagulation should be initiated approximately 5 mm from the first one.

RESUMO

OBJECTIVE: According to the ''vascular'' theory, arterial overflow in the superior hemorrhoidal arteries would lead to dilatation of the hemorrhoidal venous plexus. Hemorrhoid laser procedure (LHP) is a new laser procedure for outpatient treatment of hemorrhoids in which hemorrhoidal arterial flow feeding the hemorrhoidal plexus is stopped by laser coagulation. AIM: Our aim was to compare the hemorrhoid laser procedure with open surgical procedure for outpatient treatment of symptomatic hemorrhoids. MATERIAL AND METHOD: A comparison trial between hemorrhoid laser procedure or open surgical hemorrhoidectomy was made. This study was conducted at Aloka hospital in Kosovo. Patients with symptomatic grade III or grade IV hemorrhoids with minimal or complete mucosal prolapse were eligible for the study: 20 patients treated with the laser hemorrhoidoplasty, and 20 patients-with open surgery hemorrhoidectomy. Operative time and postoperative pain with visual analog scale, were evaluated. RESULTS: A total number of 40 patients (23 men and 17 women, mean age, 46 years) entered the trial. Significant differences between laser hemorrhoidoplasty and open surgical procedure were observed in operative time and early postoperative pain. There was a statistically significant difference between the two groups regarding the early postoperative period: 1 week, 2 weeks, 3 weeks and 1 month after respective procedure (p<0.01). The procedure time for LHP was 15.94 min vs. 26.76 min for open surgery (p<0.01). CONCLUSION: The laser hemorrhoidoplasty procedure was more effective than open surgical hemorrhoidectomy. Postoperative pain and duration time are only two indicators for this difference between there procedures.
