Angiographic description of the superior rectal artery and its anatomical variations in patients undergoing embolization of the superior rectal arteries in hemorrhoidal disease treatment.

BACKGROUND: Angiography of the superior rectal artery showed that its branches were divided into four main branches (two left and two right) in 46.8%; the second most frequent variation was one right and two left branches in 26.6%, followed by two branches to the right and one to the left in 20%; the most uncommon variations were one to the right and one to the left without further subdivision in 6.6%. BACKGROUND: ◼ The superior rectal artery, when it reaches the rectum, divides into two or more branches. BACKGROUND: ◼ Four patterns were observed in the angiographic anatomy of the superior rectal artery. BACKGROUND: ◼ Understanding the angiographic anatomy of the superior rectal artery is important to achieve optimal embolization results. OBJECTIVE: To describe angiographic findings of the superior rectal artery, its branches, and anatomical variations in the hemorrhoidal plexus in patients undergoing rectal artery embolization for hemorrhoidal disease treatment. METHODS: Angiographic findings of 15 patients were obtained from a single-center, prospective clinical study that compared superior rectal artery embolization with the Ferguson technique for hemorrhoidal disease between July 2018 and March 2020. RESULTS: Angiography of the superior rectal artery showed that in seven patients (46.8%), its branches were divided into four main branches (two left and two right), while in four patients (26.6%), the branches divided into one right and two left branches. The most uncommon variation observed in three cases (20%) was the branches divided into two branches to the right and one to the left; no further subdivision into the main branches was observed in one case (6.6%). CONCLUSION: Four patterns were observed in the angiographic anatomy of the superior rectal arteries. Knowledge of the angiographic anatomy of this region and its variations is essential to improve the effectiveness of superior rectal artery embolization. REGISTRY OF CLINICAL TRIALS: NCT03402282.

Redefining hemorrhoid therapy with endoscopic polidocanol foam sclerobanding.

Hemorrhoids are a common and painful condition, with conventional treatments such as endoscopic rubber band ligation (ERBL) and injection sclerotherapy often falling short due to high recurrence rates and significant post-operative pain. A clinical trial by Qu et al introduces a novel approach called endoscopic poli-docanol foam sclerobanding (EFSB). This multicenter randomized trial involved 195 patients with grade II and III internal hemorrhoids and demonstrated that EFSB significantly reduced recurrence rates and post-procedural pain while improving symptom relief and patient satisfaction compared to ERBL. The study's strengths include its robust design, comprehensive outcome evaluation, and patient-centered approach. Despite limitations such as the single-blind design and relatively short follow-up period, the findings suggest that EFSB could enhance clinical practice by offering a more effective and patient-friendly treatment option. Further research is needed to validate these results and explore the long-term benefits and cost-effectiveness of EFSB.

Surprising diversity of new plasmids in bacteria isolated from hemorrhoid patients.

Background: Hemorrhoids are common conditions at or around the anus, to which numerous people suffer worldwide. Previous research has suggested that microbes may play a role in the development of hemorrhoids, and the origins of these microbes have been preliminarily investigated. However, no detailed research on the microbes related to hemorrhoid patients has been conducted. This work aims to provide an initial investigation into the microbes related to hemorrhoid patients with high quality whole genome sequencing. Methods: Forty-nine bacterial strains were isolated from seven hemorrhoid patients. Third-generation nanopore sequencing was performed to obtain high quality whole genome sequences. The presence of plasmids, particularly new plasmids, along with antibiotic resistance genes, was investigated for these strains. Phylogenetic analysis and genome comparisons were performed. Results: Out of the 31 plasmids found in the strains, 15 new plasmids that have not been observed previously were discovered. Further structural analysis revealed new multidrug-resistant conjugative plasmids, virulent plasmids, and small, high-copy mobile plasmids that may play significant functional roles. These plasmids were found to harbor numerous integrases, transposases, and recombinases, suggesting their ability to quickly obtain genes to change functions. Analysis of antibiotic resistance genes revealed the presence of antibiotic resistant-integrons. Together with the surprising number of new plasmids identified, as well as the finding of transmission and modification events for plasmids in this work, we came to the suggestion that plasmids play a major role in genetic plasticity. Conclusion: This study reveals that the diversity of plasmids in human-associated microbes has been underestimated. With the decreasing cost of whole-genome sequencing, monitoring plasmids deserves increased attention in future surveillance efforts.

[The effectiveness of flavonoids in the postoperative treatment of patients with hemorrhoids]. / Effektivnost' flavonoidov v posleoperatsionnom vedenii patsientov s gemorroem.

OBJECTIVE: Evaluation of the effectiveness of flavonoids in the postoperative management of patients with hemorrhoids. MATERIAL AND METHODS: A single-center randomized controlled clinical trial was conducted. Patients with stage III and IV hemorrhoids aged over 18 years who patients who underwent hemorrhoidectomy were included.The patients were divided into 2 groups - main and control. Patients in the main group were recommended to use a purified micronized flavonoid fraction - 65 patients. In the control group (70 patients), the use of this group of drugs was not expected.The observation period was 60 days. After discharge from the hospital, 5 patient visits were scheduled: on the 3rd, 7th, 21st, 40th and 60th day after surgery. Patients independently assessed the intensity of symptoms - pain, tenesmus, itching and bleeding.The randomization procedure was carried out using the method of simple randomization using envelopes. RESULTS: 135 patients were randomized. There were no patients who dropped out of the study. The number of participants whose data were included in the analysis was 65 patients in the main group and 70 patients in the control group.Assessment of symptoms in the first 3 days of the postoperative period did not show a significant difference in the condition of the patients. Over time, we found significant changes in the dynamics of complaints between groups. After 7, 21, 40 and 60 days, a statistically significant lower severity of pain, bleeding and tenesmus was revealed among patients in the main group compared to the control group. This trend was not detected in the assessment of itching. There were no undesirable effects. CONCLUSION: The use of purified micronized flavonoid fraction in the postoperative management of patients with hemorrhoids can significantly reduce the degree and duration of pain, bleeding and tenesmus.

Effectiveness of preoperative micronized purified flavonoid fraction treatment and sucralfate-based rectal ointment on hemorrhoidal disease: A case-matched analysis.

BACKGROUND: Hemorrhoidal disease (HD) significantly impacts patients' quality of life. This study aimed to evaluate the effectiveness of preoperative treatment with the micronized purified flavonoid fraction (MPFF) and a sucralfate-based rectal ointment in managing HD symptoms and reducing interventions. METHODS: A prospective quasi-experimental study including consecutive cases and controls matched on the basis of sex was performed in a tertiary referral center. Cases received systemic and local therapy for HD, consisting of a rectal ointment containing 3% sucralfate and herbal extracts plus MPFF, in addition to conservative therapy, while controls received conservative therapy alone. The hemorrhoidal disease symptom score (HDSS), the Short Health Scale for HD (SHS-HD) score, and the Vaizey Incontinence Score were used to evaluate symptoms severity and their impact on quality of life and continence. Intervention requirements were assessed at baseline (T0) and after 60 days of treatment (T1). RESULTS: Between January and December 2023, a total of 98 patients were assessed for eligibility. After exclusions, 56 patients were enrolled, with 28 in each group. Significant improvements were observed in HD symptom scores from T0 to T1: the intervention group showed a mean change in HDSS of -9 [95% confidence interval (CI) -10 to -8], and the control group showed no significant change (mean change of 0; 95% CI -1.5 to 0). At T1, a higher proportion of patients in the intervention group underwent less invasive interventions compared with controls (18% versus 11%). Age, treatment group, and baseline symptom severity significantly predicted post-treatment symptom scores. CONCLUSIONS: In our study the preoperative treatment with MPFF and a sucralfate-based rectal ointment demonstrated clinical benefits in managing HD symptoms and reducing interventions. Further prospective trials are warranted to confirm and explore additional therapeutic strategies.

Effect of Bixie combined with perioperative multimodal analgesia management on postoperative pain and wound healing of mixed hemorrhoids.

We were to explore the effect of Bixie combined with perioperative multimodal analgesia management on postoperative pain and wound healing of mixed hemorrhoids. A total of 240 patients with mixed hemorrhoids in this hospital from June 2022 to September 2023 were chosen, with 120 in the control group receiving perioperative multimodal analgesia management and 120 in the observation group receiving Bixie combined with perioperative multimodal analgesia management. The results showed that compared with the control group, the observation group had lower visual analogue scale (VAS) scores at 1, 3, 5 and 7 days after the surgery; the 5-hydroxytryptamine (5-HT), prostaglandin E2 (PGE2), nitric oxide (NO), interleukin-2 (IL-2), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) of the observation group at 24 hours and 72 hours after the surgery were lower; the vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), platelet-derived growth factor (PDGF) and wound healing rate of the observation group at 7 days after the surgery were higher; the total effective rate of the observation group was higher. Therefore, combining Bixie with perioperative multimodal analgesia management could improve postoperative pain, decrease inflammatory factor levels, promote angiogenesis and accelerate wound healing in patients with mixed hemorrhoids.

An international observational study assessing conservative management in hemorrhoidal disease: results of CHORALIS (aCute HemORrhoidal disease evALuation International Study).

Aim: Real-world evidence on the management of hemorrhoidal disease (HD) is limited. This international study collected clinical practice data on the effectiveness of conservative treatments for acute HD on symptoms and quality of life (QoL), providing perspectives of treatment modalities from different continents. Patients & methods: The 4-week observational prospective CHORALIS study involved adult outpatients consulting for spontaneous complaints of hemorrhoids (graded using Goligher classification) and prescribed conservative treatments according to usual clinical practice. Assessments were: anal pain/discomfort (visual analog scale [VAS]), other signs/symptoms (patient questionnaire), Patient Global Impression of Change (PGI-C) questionnaire and disease-specific QoL (HEMO-FISS-QoL questionnaire). Results: Of 3592 participants, 3505 were analyzed (58.4% male; age 40.5 ± 13.7 years; history of HD in 48.4%; 72.1% Goligher grade I and II). Pain and discomfort were the most common symptoms. Most treatments were venoactive drugs (VADs; 90.9%), particularly micronized purified flavonoid fraction (MPFF; 73.7%) and diosmin (14.6%). All VAD-based therapies improved signs/symptoms (number/intensity/frequency of pain, discomfort, bleeding, swelling, itching and soiling) and QoL. MPFF was associated with a significantly greater proportion of patients with no symptoms (48.8 vs diosmin 34.4%, p < 0.001), pain disappearance (69.7 vs diosmin 52.8%, p < 0.001), treatment impact at 1 week rated on PGI-C as 'very much better' (30.5 vs diosmin 17.9%, p < 0.001) and shorter times to improvement (mean ± SD 3.9 ± 1.5 days vs diosmin 4.2 ± 1.7 days). Conclusion: In this prospective real-world study of patients with acute HD, conservative therapies consisting mainly of VADs, including MPFF, improved the clinical signs and symptoms of disease, as well as QoL. This study evidence supports clinical advantages associated with VADs, mostly MPFF, for effectively managing acute HD.

[Clinical analysis of percutaneous superselective superior rectal artery embolization for grades â ¡-â ¢ internal hemorrhoids].

Objective: To investigate the safety and efficacy of percutaneous superselective superior rectal artery embolization in the treatment of grades Ⅱ-Ⅲ internal hemorrhoids. Methods: The clinical data of 22 patients with grades Ⅱ-Ⅲ internal hemorrhoids who underwent superselective superior rectal artery embolization in the Department of Interventional and Minimally Invasive Tumor Therapy of the Second Hospital of Shandong University from September 2019 to February 2022 were retrospectively analyzed. According to the blood supply artery of hemorrhoids, superselective embolization was performed with embolization materials. The surgical efficacy,postoperative complications,and 12-month follow-up results were analyzed. The clinical score data (French bleeding score,quality of life score,prolapse score) were expressed using the median (Q1, Q3). The clinical scores before and after treatment were compared by the nonparametric rank sum test (Wilcoxon test),and the Z-value was calculated. P-values <0.05 indicate statistically significant differences. Results: The operation was successful in all 22 patients (technical success rate: 100%). The main postoperative side effects and complications included tenesmus (81.8%,18/22),anal bulge (68.2%,15/22),and mild pain in the anus (22.7%,5/22). The above reactions were improved 3-5 days after operation; three patients had congestion and dull pain at the puncture site,which improved spontaneously without treatment. The patients were followed up for 12 months. Compared with those prior to operation, the French bleeding score,quality of life score,and prolapse score were significantly improved (all P<0.05). Conclusion: Superselective superior rectal artery embolization is a relatively safe and low-risk treatment for grades Ⅱ-Ⅲ internal hemorrhoids. It is an option for the treatment of internal hemorrhoids,particularly hemorrhagic internal hemorrhoids.

Topical metronidazole after haemorrhoidectomy to reduce postoperative pain: a systematic review.

Excisional haemorrhoidectomy is the gold standard for operating haemorrhoids, but it is accompanied by a significant problem: postoperative pain. Several strategies have been adopted to minimize this condition. Oral metronidazole has been proven to reduce postoperative pain but with some complications. This systematic review was conducted to investigate the effects and general efficacy of topical metronidazole administration and to evaluate its potential superiority over the oral formula. A systematic review of the literature was carried out. Randomized controlled trials published until September 2023 on PubMed, Central, and Web of Science were considered. The primary outcome considered was postoperative pain, which was evaluated using visual analogue scores. The secondary outcomes were analgesic use, return to work, and complications. Six randomized controlled trials were included, with a total of 536 patients. Topical metronidazole was compared with placebo in two studies, with oral formula in three studies, and with placebo and oral administration in one study. Topical metronidazole was found to be effective for treating postoperative pain when compared to a placebo but had no significant advantage over the oral formula. No complications were reported in the studies. Topical and oral metronidazole are effective solutions for postoperative pain after excisional haemorrhoidectomy. No superiority was demonstrated based on the route of administration, and complications were marginal for both formulas. Further studies are required to determine the best metronidazole solution.

Comparison of gastrointestinal bleeding in patients with and without liver cirrhosis.

OBJECTIVES: Upper gastrointestinal bleeding (GIB) in patients has been well-characterized in liver cirrhosis but studies on lower GIB are limited. The clinical characteristics, management and outcomes in patients with and without liver cirrhosis was compared to determine the overall features of GIB in patients with liver cirrhosis compared with non-cirrhotics. METHODS: A retrospective study on cirrhotics hospitalized for GIB 2010-2021, matched with control group of non-cirrhotics (1:4) for upper vs. lower GIB. Patients with overt bleeding leading to hospitalization were included. RESULTS: Overall, 396 patients had cirrhosis, 267 (67%) men, median age 62, alcoholic etiology 177/396 (45%), median MELD 12 (range 6-32). Overall 102 cirrhotics had GIB, matched with 391 non-cirrhotics. Overall 87 (85%) cirrhotic patients had upper and 15% lower GIB. Compared to non-cirrhotics, the cause of GIB was more commonly acute variceal bleeding (AVB) (42% vs. 1%), hemorrhoids 40% vs. 6% (p = 0.002), less commonly gastric ulcer 13% vs. 31% (p < 0.001), duodenal ulcer 9% vs. 29% (p < 0.001), 5% of cirrhotics used NSAIDs vs. 26% of controls (p < 0.001). Rebleeding occurred in 14% of cirrhotics vs. 3% in controls (p < 0.001). Only one cirrhotic patient (1%) died from GIB vs. 0.8% of controls within 45 days. Overall mortality 45 days after hospitalization was 10% in cirrhotics vs. 5% in controls (p < 0.001). CONCLUSIONS: Bleeding from gastric and duodenal ulcers were less common in cirrhotics than in controls. Bleeding from hemorrhoids was more common in cirrhotics. Mortality due to GIB was low in both groups but overall mortality was significantly higher in cirrhotics.

Endoscopic polidocanol foam sclerobanding for the treatment of grade II-III internal hemorrhoids: A prospective, multi-center, randomized study.

BACKGROUND: Endoscopic rubber band ligation (ERBL) is a nonsurgical technique for the treatment of symptomatic internal hemorrhoids but is limited by recurrence and post-procedural pain. AIM: To evaluate satisfaction, long-term recurrence, and post-procedural pain in managing internal hemorrhoids using a combination of polidocanol foam sclerotherapy and ERBL. METHODS: This was a prospective, multicenter, randomized study. A total of 195 consecutive patients diagnosed with grade II-III internal hemorrhoids were enrolled from four tertiary hospitals and randomly divided into a cap-assisted endoscopic polidocanol foam sclerobanding (EFSB) or an ERBL group. All patients were followed-up for 12 months. Symptom-based severity and post-procedural pain were assessed using a hemorrhoid severity score (HSS) and a visual analog scale (VAS). Continuous variables were reported as medians and interquartile range. RESULTS: One hundred and ninety-five patients were enrolled, with 98 in the EFSB group. HSS was lower in the EFSB group than in the ERBL group at 8 weeks [4.0 (3.0-5.0) vs 5.0 (4.0-6.0), P = 0.003] and 12-month [2.0 (1.0-3.0) vs 3.0 (2.0-3.0), P < 0.001] of follow-up. The prolapse recurrence rate was lower in the EFSB group at 12 months (11.2% vs 21.6%, P = 0.038). Multiple linear regression analysis demonstrated that EFSB treatment [B = -0.915, 95% confidence interval (CI): -1.301 to -0.530, P = 0.001] and rubber band number (B = 0.843, 95%CI: 0.595-1.092, P < 0.001) were negatively and independently associated with the VAS score 24 hours post-procedure. The median VAS was lower in the EFSB group than in the ERBL [2.0 (1.0-3.0) vs 3.0 (2.0-4.0), P < 0.001]. CONCLUSION: Cap-assisted EFSB provided long-term satisfaction and effective relief from the recurrence of prolapse and pain 24 hours post-procedure.

Pelvic floor imaging in women with hemorrhoidal disease: An anatomical feasibility study.

OBJECTIVE: To compare pelvic floor muscle and organ structures in women with and without hemorrhoidal disease (HD) using magnetic resonance imaging (MRI). MATERIAL AND METHODS: Pelvic MRI measurements and computer-based medical records of women diagnosed with HD between January 2018 and March 2021 were analyzed. Parameters including pubococcygeal distance, puborectal distance, posterior anorectal angle, obturator internus muscle area, presence of levator ani muscle defect, genital hiatus length, vaginal length, uterocervical angle, cervix-upper vagina angle, and cervix-middle vagina angle were evaluated. The control group consisted of women without HD, matched for age and body mass index. RESULTS: Puborectal hiatus distance was higher in the HD group (59.2 â€‹± â€‹8.7 â€‹mm vs. 55.5 â€‹± â€‹7.1 â€‹mm, p â€‹= â€‹0.03). Similarly, the distance to the M line was greater in the HD group (18.3 â€‹± â€‹4.8 â€‹mm vs. 16 â€‹± â€‹4.6 â€‹mm, p â€‹= â€‹0.04). Obturator internus muscle area was found to be lower in the HD group compared to the non-HD group (1721 â€‹± â€‹291.4 â€‹mm2 vs. 1897.5 â€‹± â€‹352.5 â€‹mm2, p â€‹= â€‹0.02). Additionally, the presence of unilateral levator ani muscle defect was higher in HD patients (p â€‹= â€‹0.03). There was a negative correlation between birthweight and obturator internus muscle area (r â€‹= â€‹-0.388, p â€‹= â€‹0.02), and a positive correlation with M line distance (r â€‹= â€‹0.344, p â€‹= â€‹0.04). CONCLUSION: Levator ani muscle defects and obturator internus muscle area, indicators of pelvic floor dysfunction, are more common in patients with hemorrhoidal disease.

Comparison of Post-Hemorrhoid Surgery Pain Profiles in Older and Younger Adults.

INTRODUCTION: Older and younger adults are offered similar analgesic options after hemorrhoid surgery (HS), but the differences in pain between the two populations are unknown. This study aims to compare postoperative pain outcomes after HS in older and younger individuals. METHODS: This is a retrospective analysis of electronic medical records of patients who underwent HS between 2018 and 2023. Patients were excluded if additional anorectal procedures were performed at the time of HS. Data related to pain-related outcomes were compiled: (1) need for narcotic prescription refills; (2) documentation of a pain-related phone call within 30 d; (3) urgent postoperative office visit before regular scheduled follow-up; and (4) pain-related postoperative emergency department visits. Associations between age and pain-related outcomes were tested using Fisher's exact test, chi-square test, and covariate adjusted logistic regression modeling. RESULTS: There were a total of 249 patients, 60 older adults, and 189 younger adults. Compared to younger patients, older adults demonstrated a reduced frequency of pain-related phone calls (10.3 versus 32.1%, P < 0.01) and opioid refills (0 versus 14.4%, P < 0.01). After adjusting for confounders, older age remained inversely associated with pain-related postoperative phone calls (odds ratio = 0.25, 95% confidence interval = [0.1-0.6], P = 0.003). CONCLUSIONS: Older adults had better pain outcomes after HS in comparison to younger patients. These findings suggest that the postoperative analgesic needs of older patients after HS are lower than those of younger patients. Decisions regarding opioid prescription in older adults recovering from HS should be tailored to avoid narcotic-related complications.

Implementation of a Multimodal Enhanced Recovery Protocol in Ambulatory Anorectal Surgery: A Randomized Trial.

BACKGROUND: Few studies report outcomes for enhanced recovery pathways in ambulatory anorectal surgery. We hypothesize that an ambulatory anorectal enhanced recovery pathway with multimodal analgesia can reduce postoperative opioid use. OBJECTIVE: To compare postoperative opioid use in patients undergoing ambulatory anorectal surgery who receive multimodal analgesia versus standard of care without multimodal analgesia. DESIGN: A prospective randomized trial of patients undergoing elective anal fistula or hemorrhoid surgery from September 2018 to May 2022. SETTING: Urban teaching hospital. PATIENTS: Adults aged 18 to 70 years undergoing elective anal fistula or hemorrhoid surgery from September 2018 to May 2022. INTERVENTION: Multimodal enhanced recovery pathway including preoperative and postoperative nonopioid analgesia with oral acetaminophen, gabapentin, and ketolorac. MAIN OUTCOME MEASURES: Primary end point was oral opioid use during the first postoperative week. Secondary end points included maximum pain and nausea scores, adverse events, and emergency room or hospital admissions during the first 30 days postoperatively. RESULTS: Of the 109 enrolled patients, 20 were lost to follow-up. The remaining 89 patients had a median age of 38 years (range, 20-67) and included 41 women (46%). There were no significant differences between the enhanced recovery protocol arm and non-enhanced recovery protocol arm in terms of preoperative and surgical characteristics. The primary end point of this study, that is, oral morphine milligram equivalents use during the first week, was significantly higher among patients in the non-enhanced recovery protocol arm (79 mg; range, 0-600) than patients in the enhanced recovery protocol arm (8 mg; range, 0-390; p = 0.002). On subgroup analysis, both fistula and hemorrhoid surgery patients assigned to the non-enhanced recovery protocol arm took significantly higher oral morphine milligram equivalents in the first week than patients in the enhanced recovery protocol arm. There was no significant difference in secondary end points. LIMITATIONS: Patients and providers were not blinded. Our findings are limited to hemorrhoid and fistula surgery and may not be applicable to other anorectal procedures. CONCLUSIONS: Enhanced recovery protocols including multimodal analgesia should be used in elective anal fistula and hemorrhoid surgery to decrease postoperative opioid use. See the Video Abstract .

Presumimos que un programa anorrectal ambulatorio de recuperación acelerada con analgesia multimodal puede reducir el uso posoperatorio de opioides.OBJETIVO:Comparar el uso posoperatorio de opioides en pacientes sometidos a cirugía anorrectal ambulatoria que reciben analgesia multimodal versus atención estándar sin analgesia multimodal.DISEÑO:Un estudio prospectivo aleatorizado de pacientes sometidos a cirugía electiva de fístula anal o hemorroides desde septiembre de 2018 hasta mayo de 2022.LUGAR: Hospital universitario urbano.PACIENTES:Adultos de 18 a 70 años sometidos a cirugía electiva de fístula anal o hemorroides desde septiembre de 2018 hasta mayo de 2022.INTERVENCIÓN:Programa de recuperación acelerada multimodal que incluye analgesia no opioide pre y posoperatoria con paracetamol oral, gabapentina y ketoloraco.PRINCIPALES MEDIDAS DE RESULTADO:El resultado principal fue el uso de opioides orales durante la primera semana postoperatoria. Los resultados secundarios incluyeron puntuaciones máximas de dolor y náuseas, eventos adversos e ingresos a la sala de emergencias o al hospital durante los primeros 30 días después de la operación.RESULTADOS:De los 109 pacientes incluidos, 20 se perdieron durante el seguimiento. Los 89 pacientes restantes tenían una mediana de edad de 38 (rango, 20-67) años e incluían 41 (46%) mujeres. No hubo diferencias significativas entre los grupos del protocolo de recuperación acelerada (Grupo E) y del protocolo de recuperación no acelerada (Grupo NE) en términos de características preoperatorias y quirúrgicas. El resultado principal del estudio, el uso de MME oral durante la primera semana, fue significativamente mayor entre los pacientes del grupo NE (79 mg; rango: 0-600) que los pacientes del grupo E (8 mg; rango: 0-390) ( p = 0,002). En el análisis de subgrupos, los pacientes de cirugía de fístula y hemorroides asignados al grupo NE tomaron MME oral significativamente más alto en la primera semana que los pacientes del grupo E. No hubo diferencias significativas en los resultados secundarios.LIMITACIONES:Los pacientes y proveedores no fueron cegados. Nuestros hallazgos se limitan a la cirugía de hemorroides y fístulas y pueden no ser aplicables a otros procedimientos anorrectales.CONCLUSIONES:Se deben utilizar protocolos de recuperación acelerada que incluyan analgesia multimodal en la cirugía electiva de fístula anal y hemorroides para disminuir el uso posoperatorio de opioides.

Analysis of Two Treatment Modalities for Post-surgical Pain after Hemorrhoidectomy.

Background: This non-randomized study aimed to compare the efficacy of two pharmacological treatments, "around-the-clock" analgesic treatment (ACAT) and "on-demand" analgesic treatment (ODAT), for managing postoperative pain following hemorrhoidectomy. Material and Methods: The study, conducted from July 2016 to December 2020, included 5335 hemorrhoidectomy patients. Participants were divided into ACAT (3767) and ODAT (1568) groups. The study was registered at clinicaltrials.gov (NCT04953182). Results: Patients had a mean age of 47.47 years, with 59.98% males. Postoperatively, 14.13% reported severe pain, 36.49% moderate, 34.28% mild, and 15.09% no pain. ACAT group's maximum pain was 3.04 (VAS), ODAT 4.95 (p; average pain was 0.79 (ACAT) and 1.45 (ODAT). Discharge pain was 0.42 (ACAT) and 0.63 (ODAT) VAS. The ACAT group consistently reported lower levels of pain across all measured instances. Higher BMI and younger age were pain risk factors (p=.049, p .001 respectively). ACAT administration resulted in reduced opioid usage, with meperidine showing a 68.38% decrease, morphine 43.57% less, tramadol 46.82% less, oxycodone reduced by 38.74%, and codeine by 53.40%. Additionally, the use of non-opioid analgesics was notably lower in the ACAT group, ranging from 16% to 59% less compared to the ODAT group. Conclusion: Hemorrhoidectomy induces moderate postoperative pain, with only 14% experiencing severe pain. A fixed schedule multimodal pain regimen, regardless of procedure and anesthesia type, reduces pain from moderate to mild post-hemorrhoidectomy. This approach also decreases opioid and non-opioid analgesic requirements. Higher BMI and younger age are identified as risk factors for elevated postoperative pain.

Clinical outcomes of laser hemorrhoidoplasty with feeding vessels suture ligation: a retrospective study in a single center.

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.

Hemorrhoidal laser ablation procedure: a minimally invasive treatment for grades II, III, and IV using a 1470 nm diode laser.

Hemorrhoidal Laser Ablation, a method for treating severe hemorrhoids, has limited documentation in clinical trials.</br> <br><b>Aim:</b> This retrospective study aimed to present our experience with Hemorrhoidal Laser Ablation in symptomatic grade II, III, and IV internal hemorrhoids and evaluate the efficacy and safety of this relatively recent technique.</br> <br><b>Material and methods:</b> The cohort included 138 patients with symptomatic hemorrhoids who underwent Hemorrhoidal Laser Ablation at three different medical centers in 2017-2022. Patients were treated with a 1470 nm diode laser. Data were collected on clinical and perioperative characteristics and outcomes.</br> <br><b>Results:</b> No evidence of intraoperative complications occurred. There was no rectal tenesmus or alteration of defecation habits. Early mild postoperative symptoms were observed for an average of one week after the operation. The plateau of symptom resolution and downgrading of hemorrhoid size reached approximately six months post-procedure. The short- -term recurrence rate was 0.8% within roughly a month after the laser surgery, while the long-term recurrence rate was 5% over up to five years of follow-up. The overall satisfaction rate was 95% with symptomatic relief.</br> <br><b>Conclusions:</b> Hemorrhoidal Laser Ablation is a painless outpatient technique that does not require general anesthesia. It is an easy-to-perform, convenient, safe, and efficient modality in reducing symptoms and complications of grades II, III, and IV internal hemorrhoids. Hemorrhoidal Laser Ablation limits postoperative discomfort and allows the patient to return to daily routines quickly.</br>.

A systematic review comparing the efficacy of 980 nm vs. 1470 nm wavelengths in laser hemorrhoidoplasty.

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.

Inflammatory bowel disease and risk for hemorrhoids: a Mendelian randomization analysis.

Observational studies have reported an association between inflammatory bowel disease (IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC), and hemorrhoids (HEM). However, the presence of a causal relationship within this observed association remains to be confirmed. Consequently, we utilized the Mendelian randomization (MR) method to assess the causal effects of IBD on hemorrhoids. We validated the association between IBD and hemorrhoids in humans based on genome-wide association studies (GWAS) data. To investigate the causal relationship between IBD and hemorrhoids, we performed a two-sample Mendelian randomization study using training and validation sets. The genetic variation data for IBD, CD, UC, and hemorrhoids were derived from published genome-wide association studies (GWAS) of individuals of European. Two-sample Mendelian randomization and Multivariable Mendelian randomization (MVMR) were employed to determine the causal relationship between IBD (CD or UC) and hemorrhoids. Genetically predicted overall IBD was positively associated with hemorrhoids risk, with ORs of 1.02 (95% CIs 1.01-1.03, P = 4.39 × 10-4) and 1.02 (95% CIs 1.01-1.03, P = 4.99 × 10-5) in the training and validation sets, respectively. Furthermore, we found that CD was positively associated with hemorrhoids risk, with ORs of 1.02 (95% CIs 1.01-1.03, P = 4.12 × 10-6) and 1.02 (95% CIs 1.01-1.02, P = 3.78 × 10-5) for CD in the training and validation sets, respectively. In addition, we found that UC in the training set was positively associated with hemorrhoids risk (ORs 1.02, 95% CIs 1.01-1.03, P = 4.65 × 10-3), while no significant causal relationship between UC and hemorrhoids was shown in the validation set (P > 0.05). However, after MVMR adjustment, UC in the training set was not associated with an increased risk of hemorrhoids. Our study showed that there is a causal relationship between CD and hemorrhoids, which may suggest that clinicians need to prevent the occurrence of hemorrhoids in CD patients.
