Ethanol endometrioma sclerotherapy: safety through 8 years of experience.

STUDY QUESTION: What are the complications of transvaginal ethanol sclerotherapy for the treatment of endometriomas? SUMMARY ANSWER: Sclerotherapy is a reliable, minimally invasive method applicable in outpatient procedures but with specific and potential life-threatening complications that need to be identified and prevented. WHAT IS KNOWN ALREADY: There are currently few data on the use of transvaginal ethanol sclerotherapy, and we mainly note septic complications. STUDY DESIGN, SIZE, DURATION: A retrospective observational cohort study was carried out. The study was conducted at an academic hospital and included 126 women aged 31.9 ± 5.5 years (mean ± SD), between November 2013 and June 2021. We analyzed a total of 157 ethanol sclerotherapy treatment (EST), treated by 131 EST procedures, in 126 women. PARTICIPANTS/MATERIALS, SETTING, METHODS: The study included women with an indication for transvaginal ethanol sclerotherapy. Indications were women with at least one endometrioma over 10 mm, isolated or associated with other endometriosis locations, requiring treatment for pain or infertility before assisted reproductive treatment. We followed a standardized transvaginal ethanol sclerotherapy procedure consisting of an ultrasound-guided transvaginal puncture of one or more endometriomas under general anesthesia. The cyst content was completely removed and flushed with saline solution. Ethanol (96%) was injected at 60% of the initial volume of the endometrioma, remained in the cyst for 10 min and was then completely removed. Ethanol loss was defined as a loss of 5 ml or more than 10% of the initial volume of the injected ethanol. Failure was defined by the contraindication of endometrioma puncture because of interposition of the digestive tract, ethanol loss in the previous endometrioma treated (in case of multiple ESTs), failure to aspirate the endometriotic fluid, contraindication to start ethanol injection owing to saline solution leakage, or contraindication to continue ethanol injection owing to suspicions of ethanol leakage at sonography. Intraoperative complications were defined by ethanol loss, positive blood alcohol level, and ethanol intoxication. Postoperative complications were defined by fever, biological inflammatory syndrome, and ovarian abscess. Complications were classified according to the Clavien and Dindo surgical classification, which is a system for classifying postoperative complications in five grades of increasing severity. MAIN RESULTS AND THE ROLE OF CHANCE: We reported a total of 17/157 (10.8%) transvaginal ethanol sclerotherapy failures during 14/131 (10.7%) transvaginal ethanol sclerotherapy procedures in 13/126 (10.3%) women. In the same sets of data, complication was reported for 15/157 (9.5%) transvaginal ethanol sclerotherapy in 13/131 (9.9%) transvaginal ethanol sclerotherapy procedures in 13/126 (10.3%) women. Nine of 126 women (7.1%) had a grade I complication, one (0.8%) had a grade II complication (medical treatment for suspicion of pelvic infection), two (1.6%) had a grade III complication (ovarian abscess) and one (0.8%) had a grade IV complication (ethanol intoxication). We did not observe any grade V complications. LIMITATIONS, REASONS FOR CAUTION: This was a retrospective study and pain assessment not considered. The benefit-risk balance of endometrioma transvaginal ethanol sclerotherapy was not evaluated. WIDER IMPLICATIONS OF THE FINDINGS: Our study is the first to evaluate the complications of transvaginal ethanol sclerotherapy with such a large cohort of women in a standardized protocol. Transvaginal ethanol sclerotherapy seems to be an effective alternative to laparoscopic surgery in the management of endometriomas and limits the alteration of ovarian reserve. Transvaginal ethanol sclerotherapy is a reliable, minimally invasive method applicable on an outpatient basis. The majority of complications are Clavien-Dindo ≤IV, for which preventative measures, or at least early diagnosis and treatment, can be easily performed. The risk of ethanol intoxication is rare, but it is a life-threatening risk that must be avoided by appropriate implementation and promotion of the sclerotherapy procedures.

Outcome of bleomycin electrosclerotherapy of slow-flow malformations in adults and children.

OBJECTIVES: To evaluate the safety and clinical outcome of bleomycin electrosclerotherapy (BEST) for treating extracranial slow-flow malformations. METHODS: In this retrospective investigation of a multicenter cohort presenting symptomatic slow-flow malformations, patient records were analyzed with respect to procedural details and complications. A treatment-specific, patient-reported questionnaire was additionally evaluated, obtained 3-12 months after the last treatment, to assess the subjective outcomes, including mobility, aesthetic aspects, and pain, as well as the occurrence of postprocedural skin hyperpigmentation. All outcome parameters were compared according to patients' age. RESULTS: Overall, 325 BEST treatments were performed in 233 patients after intralesional and/or intravenous bleomycin injection. The total complication rate was 10.2% (33/325), including 29/352 (8.9%) major complications. Patient-reported mobility decreased in 10/133 (8.8%), was stable in 30/113 (26.5%), improved in 48/113 (42.5%), and was rated symptom-free in 25/113 (22.1%) patients. Aesthetic aspects were rated impaired compared to baseline in 19/113 (16.8%), stable in 21/133 (18.6%), improved in 62/113 (54.9%), and perfect in 11/133 (9.7%) patients. Postprocedural skin hyperpigmentation occurred in 78/113 (69%) patients, remaining unchanged in 24/78 (30.8%), reduced in 51/78 (65.5%), and completely resolved in 3/78 (3.8%) patients. The median VAS pain scale was 4.0 (0-10) preprocedural and 2.0 (0-9) postprocedural. Children/adolescents performed significantly better in all parameters compared to adults (≥ 16 years) (mobility, p = 0.011; aesthetic aspects, p < 0.001; pain, p < 0.001). CONCLUSIONS: BEST is effective for treating slow-flow vascular malformations, with few but potentially significant major complications. Regarding patient-reported outcomes, children seem to benefit better compared to older patients, suggesting that BEST should not be restricted to adults. CLINICAL RELEVANCE STATEMENT: Bleomycin electrosclerotherapy is a safe and effective approach and therapy should not be restricted to adults due to good clinical outcomes in children.

Systematic review and network meta-analysis of hydrosalpinx treatment before in vitro fertilization.

OBJECTIVES: To compare different methods to treat hydrosalpinx, based on both ablative and non-ablative approaches, in infertile patients before undergoing IVF-ET. METHODS: Systematic review and network meta-analysis (NMA) of comparisons between different treatments of hydrosalpinx in infertile patients undergoing IVF. DATA SOURCES: structured searches in common citation databases. Study inclusion criteria: peer-reviewed randomized trials (RCT) or cohort studies comparing effects of salpingectomy, laparoscopic proximal tubal occlusion (LTO), insertion of intratubal device (ITD), sclerotherapy, ultrasound-guided aspiration and no treatment, on live birth, ongoing pregnancy, clinical pregnancy as main outcomes, considering also miscarriage, ectopic pregnancy and complications as secondary outcomes. Principal NMA included RCT, and aggregated NMA of RCT and observational studies was carried out. Pooled effects have been estimated by Odds Ratio (OR) and its 95% confidence interval (CI) for direct and indirect-mixed comparisons, derived from random-effects models. Imprecision and heterogeneity of NMA estimations was assessed by comparison of its 95% CI with predefined intervals for clinically relevant size of effect (OR <0.9 or >1.1). Surface under the cumulative ranking curve (SUCRA) were used to predict treatment rankings for each outcome. RESULTS: Nine RCT were included in main analysis, plus 17 additional observational studies in additional analysis. NMA of RCT did not identify significant differences in the effect of compared treatments on live birth rate, and LTO was the option with the highest value of SUCRA (0.92, mean rank: 1.2). Salpingectomy and US-aspiration associated to a significant increase of ongoing pregnancy rate compared to no treatment, according to NMA results (NMA OR: 4.35; 95% CI: 1.7, 11.14 and 2.8; 95% CI: 1.03, 7.58 respectively). Salpingectomy had the highest SUCRA value (0.88, mean rank: 1.4). NMA estimated significant increase of clinical pregnancy rate for salpingectomy compared with no treatment (NMA OR: 2.24; 95% CI: 1.3, 3.86) as well as for LTO versus no treatment (NMA OR: 2.55; 95% CI: 1.2, 5.41). Both comparisons were affected by a high grade of heterogeneity. For clinical pregnancy, LTO was the intervention with highest SUCRA (0.85; mean rank: 1.6). Regarding secondary outcomes, feasible NMA estimates did not support significant differences between treatments effects. According to aggregated NMA including randomized and observational studies, sclerotherapy showed significant beneficial effects on live birth rate compared to no treatment (NMA (OR: 4.6; 95% CI: 1.21, 17.46). Compared with untreated patients, the aggregated NMA estimates a higher ongoing pregnancy rate in patients treated with salpingectomy (NMA OR: 3.35; 95% CI: 2.12, 5.12), US-aspiration (NMA OR: 2.16; 95% CI: 1.28, 3.65) and LTO (NMA OR: 2.46; 95% CI: 1.11, 5.43). Salpingectomy and LTO produced a higher beneficial effect compared to ITD, based on both direct and indirect comparisons. Salpingectomy obtained the highest SUCRA value in rank of effects on ongoing pregnancy (0.94; mean rank: 1.2). NMA found significant effects on clinical pregnancy for comparisons between the different active management procedures compared with no treatments, with the exception of ITD insertion. LTO had more increasing effect on clinical pregnancy rate compared with US-aspiration (NMA OR: 2.04; 95% CI: 1.05, 3.97), while for the rest of the comparisons between procedures no significant differences were identified. NMA ranked LTO as the treatment with a highest SUCRA value (0.91; mean rank: 1.5). NMA prediction models identified LTO as best intervention to reduce miscarriage (SUCRA value: 0.84; mean rank: 1.8), as sclerotherapy as safer option in terms of ovarian response to IVF stimulation. CONCLUSIONS: The present NMA fails to support the effectiveness of any option to treat hydrosalpinx before IVF in order to improve live birth rates, although the beneficial effect of salpingectomy and US aspirations on ongoing pregnancy rates and of both salpingectomy and LTO on clinical pregnancy rates emerges from our analysis, which reinforces current recommendations. Based on the aggregated analyses, sclerotherapy could be a promising alternative to conventional laparoscopic techniques, combined with a favorable safety profile.

The efficacy of sclerotherapy as the initial treatment in patients with bleeding from Dieulafoy's lesion of the upper gastrointestinal tract.

BACKGROUND: Dieulafoy's lesion (DL) is a rare and important cause of acute nonvariceal upper gastrointestinal bleeding (ANVUGIB), however, there is a lack of clear guidelines focus on the endoscopic hemostasis treatment for DL. Sclerotherapy, as the ANVUGIB guideline recommended endoscopic hemostasis method, is widely used in clinical practice. The aim of this study is to investigate the efficacy of sclerotherapy as the initial treatment for Dieulafoy's lesion of the upper gastrointestinal tract (UDL). METHODS: Patients with UDL who underwent the ANVUGIB standard endoscopic hemostasis between April 2007 and January 2023 were enrolled. The endoscopic therapy method was left to the discretion of the endoscopist. RESULTS: In total, 219 patients were finally obtained, with 74 (33.8%) receiving sclerotherapy and 145 (66.2%) receiving other standard endoscopic therapy. The rebleeding within 30 days was significantly lower in the sclerotherapy group compared to the other standard group (5.8% vs. 16.8%, p = 0.047). There were no significant differences between the two groups in terms of successful hemostasis rate (93.2% vs. 94.5%, p = 0.713), median number of red blood cell transfusions (3.5 vs. 4.0 units, p = 0.257), median hospital stay (8.0 vs. 8.0 days, p = 0.103), transferred to ICU rate (8.1% vs. 6.2%, p = 0.598), the need for embolization or surgery rate (12.2% vs. 9.7%, p = 0.567) and 30-day mortality (0 vs. 2.1%, p = 0.553). In addition, we found no difference in efficacy between sclerotherapy alone and combination (3.1% vs. 8.1%, p = 0.714). Further analysis revealed that thermocoagulation for hemostasis was associated with a higher rate of rebleeding (28.6% vs. 3.1%, p = 0.042) and longer hospital stay (11.5 vs. 7.5 days, p = 0.005) compared to sclerotherapy alone. CONCLUSION: Sclerotherapy represents an effective endoscopic therapy for both alone and combined use in patients with upper gastrointestinal Dieulafoy's lesion. Therefore, sclerotherapy could be considered as initial treatment in patients with bleeding of UDL.

Percutaneous microwave ablation versus sclerotherapy for large hepatic hemangioma: a multi-center cohort study.

OBJECTIVE: The study aimed to compare the effectiveness and safety of ultrasound-guided microwave ablation (MWA) and percutaneous sclerotherapy (PS) for the treatment of large hepatic hemangioma (LHH). METHODS: This retrospective study included 96 patients who underwent MWA (n = 54) and PS (n = 42) as first-line treatment for LHH in three tertiary hospitals from January 2016 to December 2021. Primary outcomes were technique efficacy rate (volume reduction rate [VRR] > 50% at 12 months), symptom relief rate at 12 months and local tumor progression (LTP). Secondary outcomes included procedure time, major complications, treatment sessions, cost and one-, two-, three-year VRR. RESULTS: During a median follow-up of 36 months, the MWA group showed a higher technique efficacy rate (100% vs. 90.4%, p = .018) and symptom relief rate (100% vs. 80%, p = .123) than the PS group. The MWA group had fewer treatment sessions, higher one-, two- and three-year VRR, lower LTP rate (all p < .05), longer procedure time and higher treatment costs than the PS group (both p < .001). MWA shared a comparable major complications rate (1.8% vs. 2.4%, p = .432) with PS. After multivariate analysis, the lesion's heterogeneity and maximum diameter >8.1 cm were independent risk factors for LTP (all p < .05). In the PS group, lesions with a cumulative dose of bleomycin > 0.115 mg/cm3 had a lower risk of LTP (p = .006). CONCLUSIONS: Both MWA and PS treatments for large hepatic hemangioma are safe and effective, with MWA being superior in terms of efficacy.

Adjunct role of liquid absolute alcohol intralesional sclerotherapy during the surgical management of spinal primary aneurysmal bone cyst in a child: a technical case report.

BACKGROUND: Aneurysmal bone cyst is composed of variable -sized cystic blood-filled spaces separated by connective tissue septae. First-line surgical resection of spinal aneurysmal bone cyst in a child with limited total blood volume can lead to massive intraoperative bleeding, thus limiting extent of resection. Our Centre's has good experience of using absolute alcohol as an effective immediate devascularizing agent during vertebral hemangioma surgery in children. MATERIAL AND METHODS: We report the first case of pediatric lumbar primary aneurysmal bone cyst in which completely blood-less piecemeal total resection of the lesion was performed after intraoperative absolute alcohol intralesional sclerotherapy. RESULTS: Completely blood-less piecemeal total resection of the lumbar aneurysmal bone cyst was performed after intraoperative absolute alcohol intralesional sclerotherapy. CONCLUSION: Intraoperative absolute alcohol intralesional sclerotherapy is a very effective devascularizing adjunct for complete piecemeal resection of spinal aneurysmal bone cyst in children with limited blood volume.

Arteriovenous malformations as a presenting sign of PTEN hamartoma tumor syndrome: A case series.

High-flow vascular malformations have been associated with multiple syndromes including capillary malformation-arteriovenous malformation (CM-AVM) syndrome, hereditary hemorrhagic telangiectasia syndrome, and less commonly, phosphatase and tensin homolog hamartoma tumor syndrome (PHTS). We present a series of three patients with clinically challenging complex AVMs who were found to have underlying PHTS. In all patients, diagnosis was delayed, and the presence of the AVM prompted sampling and genetic testing for PHTS in the absence of other clinical features of the condition. This series highlights the importance of screening for PHTS in the setting of high-flow vascular malformations.

Navigating the spectrum of pediatric sialorrhea management: A narrative review.

OBJECTIVE: This review summarizes the approaches to pediatric sialorrhea management from least-to-most invasive: non-pharmacological management, anticholinergic medications, botulinum neurotoxin, non-invasive surgery, and invasive surgical intervention. REVIEW METHODS: An electronic literature review identified English-language articles on sialorrhea management in pediatric patients. Publications between 1982 and 2022 were used, with a focus on articles published from 2012 to 2022. Additional augmentation of pharmacologic information was obtained from the latest editions of medical textbooks supplemented with official package inserts of investigated medications. CONCLUSIONS: Sialorrhea is abnormal in patients greater than four years of age. Severe cases warrant intervention to improve patient quality of life and reduce caregiver burden. Management starts with conservative approaches. Viable candidates begin with non-pharmacological management options. Anticholinergic medications can decrease saliva production, but adverse side effects may outweigh benefits. Botulinum neurotoxin injection of the salivary glands decreases salivary flow rate; however, relief is transient and thus multiple treatments are required. Non-invasive sclerotherapy is an emerging treatment option showing promising results for sialorrhea. In contrast, surgical intervention is reserved as a last-resort treatment for patients with severe symptoms, due to its higher risk for adverse consequences. IMPLICATIONS FOR PRACTICE: Physicians should be familiar with the different pediatric sialorrhea management options, including advantages and disadvantages, to adequately facilitate shared decision making with caretakers of pediatric patients who require treatment.

Sclerotherapy vs. surgical excision for lymphatic malformations of the head and neck: a systematic review and meta-analysis.

OBJECTIVES: Lymphatic malformations (LMs) are abnormal lymphatic vessels with cystic characteristics, categorized as macrocystic, microcystic, or a combination of both. They represent the second most common vascular malformations, and their management involves multidisciplinary approaches based on clinical assessments and imaging studies. LMs manifest as a challenge to medical professionals in the head and neck, posing functional and aesthetic concerns. Our systematic review aims to compare the efficacy of sclerotherapy and surgery for LMs, identifying optimal treatment modalities for each scenario. METHODS: We searched four electronic databases for related studies. Data were extracted from the included studies. We calculated the pooled rate ratios with 95% confidence intervals (CIs). The I2 test was used to detect heterogeneity. The inclusion of the studies required the following prerequisites: 1- Studies focusing on any lymphatic malformations in the head and neck, whether microcystic, macrocystic, or a mix of both; 2- Studies performed on more than ten patients; 3- All interventions used as surgery, sclerotherapy, or both. RESULTS: We included 58 studies in our systematic review, of which 45 were eligible for the meta-analysis. For macrocystic LMs, sodium tetradecyl sulfate (STS) mixed with ethanol and excision achieved the highest complete response rates at (92.9%) and (92.5%), respectively. Surgical excision showed the lowest poor response rate. Polidocanol microfoam had the highest poor response rate (11.1%). In microcystic LMs, combining sclerotherapy with excision showed the highest complete response rate (70.3%) and the lowest poor response rate (1.3%). Picibanil had the lowest complete response rate (9.1%) and the highest rate of poor response (61.4%). In mixed LMs, surgical excision had the highest complete response rate (70.3%). CONCLUSION: Both surgical excision and STS combined with ethanol are highly effective for treating macrocystic LMs, achieving similar complete response rates. The combination of sclerotherapy and surgical excision demonstrated the best outcomes in microcystic LMs. Surgical excision demonstrates superior efficacy over sclerotherapy for mixed LMs. These findings suggest that excision is generally more effective in achieving complete and excellent responses across all LM subtypes. Further high-quality studies are necessary to standardize and optimize treatment protocols.

Sclerotherapy for hemorrhoidal disease: systematic review and meta-analysis.

BACKGROUND: This systematic review and meta-analysis aimed to evaluate the safety and efficacy of sclerotherapy methods for hemorrhoidal disease (HD) over the past 40 years. METHODS: The review followed the 2020 Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. A comprehensive literature search was conducted, including studies reporting the use of sclerotherapy in patients with HD. Study eligibility criteria were defined, and data were extracted independently by the authors. Random-effects meta-analyses were performed to assess outcomes of interest. RESULTS: Out of 1965 records identified, 44 studies met the inclusion criteria, involving 9729 patients. The majority of studies were conducted in Japan, followed by the UK, Italy, and Portugal. The median age of participants was 52 years, and the majority were male. The Goligher grade distribution indicated varying degrees of HD severity. Sclerotherapy was predominantly administered through anoscopy, with polidocanol being the most commonly used agent. The procedure was generally performed without pre-injection analgesia. The meta-analysis of 14 randomized controlled trials (RCTs) revealed that sclerotherapy was not inferior to control interventions in terms of success rate (risk ratio [RR] 1.00, 95% CI 0.71-1.41) and recurrence rate (RR 1.11, 95% CI 0.69-1.77), while resulting in fewer complications (RR 0.46, 95% CI 0.23-0.92). CONCLUSIONS: This systematic review highlights the safety and efficacy of sclerotherapy for HD, which yields similar success rates and fewer complications compared to other conservative or surgical approaches. Further research is warranted to optimize sclerotherapy techniques and evaluate long-term outcomes. REGISTRATION: PROSPERO 2023 CRD42023396910.

Complications of pediatric macrocystic lymphatic malformations of the head and neck: a survival analysis of treated and untreated patients.

OBJECTIVE: To compare events of recurrent swelling between treated and untreated patients with macrocystic lymphatic malformations of the head and neck not involving the airway. The frequency and timing of emergency department (ED) visits related to the event were analysed to provide data on efficacy and ideal timing of treatment. METHODS: A 5-year retrospective review of a hospital database was conducted reviewing 35 patients (15 female, 20 male; mean age 3.9 years) with macrocystic lymphatic malformations of the head and neck not involving the airway. Patients treated with oral medications were excluded. A survival analysis was performed comparing the incidence of recurrent swelling of the malformation. A Cox regression analysis was conducted using age, gender, diameter of lymphatic malformation at presentation, and echogenicity on US as covariates. Fisher's test and mean comparisons were performed to correlate the populations baselines and the number and frequency of ED visits between the 2 groups. RESULTS: Thirteen patients underwent sclerotherapy soon after initial presentation and 22 elected for observation. The two baseline populations differed at presentation with the treatment group being younger (1.4 ± 2.4 vs. 5.4 ± 6.3 years, p = 0.03) and with larger lesions (5.7 ± 2.7 vs. 4.0 ± 1.7 cm p = 0.03). Mean follow-up time was 2.7 years. Survival analysis showed 1 or multiple recurrences affected 16 patients in the untreated group and 3 patients in the treated group. (p = 0.04). Age, gender, diameter of the lesion at presentation and increased echogenicity on US were not predictive factors of recurrence. Although the probability of visiting the ED at least once did not differ between the two groups (p = 0.42), patients from the non-treatment group were more likely to visit the ED more than once (p = 0.03). CONCLUSIONS: Sclerotherapy treatment may reduce the chance of recurrent swelling or an event after initial presentation to the ED.

Deep vein thrombosis after sclerotherapy and endovenous laser ablation of varicose veins - an observational study.

Background: The risk of developing deep vein thrombosis (DVT) after endovenous ablation of varicose veins varies in the literature. Little is known about the characteristics of this complication and associated factors. This study aimed: 1) to study the occurrence of DVT after ultrasound-guided foam sclerotherapy (UGFS) alone or combined with endovenous laser ablation (EVLA) for lower-limb varicose veins; 2) to identify factors associated with DVT. Patients and methods: The study included all outpatients aged 18 years or older who underwent UGFS and EVLA or UGFS alone at the University Hospital of Zurich between 2011 and 2015. Data were extracted from the hospital electronic medical record. Patients were surveyed about their level of pain after the procedure and their level of satisfaction with the procedure. Duplex ultrasound was used to assess the deep venous system 7-10 days and 6-8 months after the procedure. Regression analysis was used to examine the association of patient and procedure characteristics with the development of DVT. Results: A total of 334 patients (561 procedures performed in 393 different sessions) were included: 73% of the patients underwent combined UGFS and EVLA and 27% underwent UGFS alone. DVT occurred in 24 (7.2%) patients, of whom 88% underwent combined procedures and 17% underwent interventions involving both the great and small saphenous veins on the same session. DVT occurred in 8.2% of patients receiving thromboprophylaxis and in 9.5% of patients not receiving thromboprophylaxis. DVT occurred in 5.2% of women and 11.9% of men. No factors associated with a diagnosis of DVT after intervention were identified. Pain and satisfaction levels did not differ between patients with and without DVT. Conclusions: This study adds to the knowledge of the risk of DVT following UGFS alone or combined with EVLA. Further studies are needed to revise thromboprophylaxis.

The Efficacy and Safety of Transvaginal Ethanol Sclerotherapy in the Treatment of Endometrial Cysts-A Systematic Review.

Endometriosis, as a chronic disorder that is a source of severe pain ailments and infertility, requires a comprehensive therapeutic approach. Sclerotherapy, consisting of the administration of sclerosing agents into the cyst, is a constantly evolving minimally invasive treatment method for this disease. Hence, the main objective of this systematic review was to evaluate the impact of its most often used variant, transvaginal ethanol sclerotherapy, on endometriosis-related symptoms, endometrial cyst recurrence rate, ovarian reserve, assisted reproductive technology (ART) outcomes, and pregnancy outcomes, as well as to assess potential complications resulting from this treatment. This systematic review was undertaken using PubMed, Scopus, Web of Science, and Cochrane Library databases on 24 November 2023. The risk of bias in included studies was assessed with the use of the Newcastle-Ottawa scale (NOS) and the revised Cochrane risk of bias 2.0 tool for randomized controlled trials. From the 1141 records obtained from all databases, 16 studies have been included in this review. The use of ethanol sclerotherapy was characterized by a low rate of post-procedural complications. The recurrence rate of endometrial cysts after the procedure depended on the ethanol instillation time within the cyst. Although ethanol sclerotherapy had negligible influence on ovarian reserves when compared to laparoscopic cystectomy, the effects of both these methods on pregnancy outcomes were comparable. This review identifies that sclerotherapy is safe, provides significant relief of symptoms, and does not impair the reproductive potential of the patients.

Sclerotherapy in the Treatment of Hydroceles: A Comprehensive Review of the Efficacy, Types of Sclerosants, and Comparative Outcomes Against Hydrocelectomy.

While hydrocelectomy is the gold-standard for treating hydroceles, it poses an increased risk to patients and a greater burden to the healthcare system. Sclerotherapy is an alternative treatment for hydroceles that involves injecting a sclerosant into the hydrocele under ultrasound guidance. This literature review aimed to assess the types of sclerosants used and how sclerotherapy compares to hydrocelectomy. A literature search was conducted of MEDLINE and EMBASE using the terms "sclerotherapy" and "hydrocelectomy," which yielded 1058 studies, of which 29 met the inclusion criteria. Only studies published after 2000 were included to ensure the most recent information was reviewed. The results showed hydrocele sclerotherapy is done using a variety of sclerosants. The most used agents are polidocanol, phenol, and STS. Of these, phenol had the highest clinical success rate of 96.5%. There was evidence for the use of atypical agents, such as tetracycline antibiotics, which yielded cure rates up to 93%, and alcohol, which was found to be especially useful for treating multiseptated hydroceles. The results comparing sclerotherapy to hydrocelectomy indicated hydrocelectomy to be a more effective method in completely curing hydroceles. However, this came at the cost of more complications. Additionally, sclerotherapy was found to be more advantageous for secondary outcomes, such as healthcare costs and burden to patients. In conclusion, this review shows that while hydrocelectomy is more effective, sclerotherapy is a valuable alternative for treating hydroceles. Due to the lack of standardization among studies, a definitive conclusion cannot be made regarding which sclerosant is best to use.

Aluminum potassium sulfate and tannic acid (ALTA) sclerotherapy for hemorrhoidal disease: a systematic review and meta-analysis.

BACKGROUND: We conducted a systematic review to assess the safety and efficacy of Aluminum potassium sulfate and tannic acid (ALTA) sclerotherapy for the treatment of hemorrhoidal disease. METHODS: Our study was conducted in accordance with the PRISMA statement (Preferred Reporting Items for Systematic Reviews and Meta-analyses) 2020. Primary endpoints included overall recurrence and type of recurrence while secondary endpoints included postoperative complications, reintervention, presence of rectal ulcer, rectal stricture, defecation abnormalities and perianal abscess. Α regression analysis, where the percentage of patients with grade II, III and IV hemorrhoidal disease was used as a covariate, was also performed. RESULTS: Twelve studies with 4249 patients met all the inclusion criteria and were eventually included. The crude and pooled estimates of the overall recurrence and complications by the end of follow-up were 10% (95% CI, 6.52%-14.08%) and 5.20% (95% CI, 2.59%-8.52%), respectively. Regression analysis displayed no correlation between recurrence and the grade of hemorrhoid disease II, ß= -0.0012 (95% CI, -0.0074 to 0.0049) (p = .64), grade III ß= -0.0006 (95% CI, -0.0056 to 0.0045) (p = .79) and grade IV ß = 0.0025 (95% CI, -0.0075 to 0.0124). However, a trend suggestive of increased recurrence was observed in patient populations with a higher proportion of grade IV disease. CONCLUSION: ALTA sclerotherapy may be a safe and viable alternative for patients with hemorrhoidal disease. Long-term follow-up and high-quality randomized controlled trials will help define the place of ALTA sclerotherapy in the armamentarium of treatment of hemorrhoids.

[Management of pediatric vascular malformations]. / Management vaskulärer Malformationen im Kindesalter.

BACKGROUND: Vascular malformations belong to the group of vascular anomalies. They are rare congenital diseases resulting from abnormal development of vessels and can arise in any location, often in the head and neck region. Clinical symptoms are variable, functional handicaps and esthetic problems may result. MATERIALS AND METHODS: One differentiates between arteriovenous, lymphatic, venous, and capillary malformations and combinations thereof. Their classification, symptoms, diagnostics, and treatment options are discussed. RESULTS: The different types of vascular malformations as well as their clinical presentation, diagnostic workup, and therapeutic options are presented, supported by clinical examples. CONCLUSION: Interdisciplinary care of pediatric patients with vascular malformations is essential in order to generate a treatment concept after correct diagnosis and improve symptoms and quality of life.

Sclerotherapy for the intraoral ranula with bleomycin: technical considerations and preliminary experience.

Ranula is a mucous cyst that occurs in the sublingual gland (SLG) in the floor of the mouth. It can be classified into two types based on origins: One is the the lesser sublingual gland (LSLG) in the anterior segment and the Rivini duct, which is connected to it, and the other is the greater sublingual gland (GSLG) in the posterior segment. Because of the anatomical characteristics, surgical resection of the cysts carries the risk of damaging adjacent tissues and has a high recurrence rate. Intralesional injection of sclerotherapy may be a better alternative treatment. We summarized 65 cases of ranula treated with intralesional injections of bleomycin(BML). According to the origin of the ranula, 60 cases were from the LSLG and the Rivini duct, and 5 cases were from the GSLG. The results showed that 60 cases of ranula from LSLG and Rivini ducts were 100% cured during the follow-up period. The median number of injections for all patients was 1.16. All 5 cases of ranula from the GSLG did not wholly recover. This study confirmed that BLM intralesional injection is a safe and effective treatment modality for cysts from LSLG or the ducts of Rivini rather than GSLG. Therefore, before treatment, it is necessary to determine the type and origin of the cyst by characterizing its morphology to ensure the effectiveness of the treatment.

Surgical Management and Denosumab for Aneurysmal Bone Cysts of the Spine in an Australian Tertiary Paediatric Centre.

Aneurysmal bone cysts (ABC) are rare osteolytic, benign but often locally aggressive tumours of the long bones or vertebrae. For spinal ABC, surgical management, embolisation or sclerotherapy alone often carry high morbidity and/or high recurrence rates. Interruption of receptor activator of nuclear factor-kappa B ligand (RANKL) signalling holds promise as an effective therapeutic strategy for these tumours. We aimed to review the approach to surgical management and evaluate the efficacy and safety of denosumab for ABC of the spine in children. Retrospective review of 7 patients treated with denosumab using a standardised protocol for ABC of the spine in a tertiary paediatric centre. Surgical intervention was only conducted if there was spinal instability or significant neurological impairment. Denosumab 70 mg/m2 was given 4-weekly for at least 6 months, followed by 2 doses of zoledronate 0.025 mg/kg, aiming to prevent rebound hypercalcaemia. All patients achieved stability of the spine and resolution of neurological impairment, if present. Six patients achieved metabolic remission and have ceased denosumab without recurrence to date; the other showed clinical and radiological improvement without complete metabolic remission. Three patients developed symptomatic hypercalcaemia 5-7 months after cessation of denosumab, requiring additional bisphosphonate treatment. We present our algorithm for the surgical and medical management of paediatric spinal ABC. Denosumab produced a radiological and metabolic response in all patients, with complete remission in most. Follow-up time was not long enough to evaluate the endurance of response after cessation in some patients. Incidence of rebound hypercalcaemia in this paediatric cohort was high, prompting a change to our protocol.

Effect of catheter-directed ethanol sclerotherapy on ovarian reserve in patients with recurrent endometrioma: comparative analysis with primary endometriosis.

OBJECTIVE: Catheter-directed ethanol sclerotherapy (CDS) is known to less affect the ovarian function, with comparable efficacy. This study aims to investigate the change in ovarian reserve after catheter-directed ethanol sclerotherapy in patients with recurrent endometrioma, as compared to primary endometrioma. MATERIALS AND METHODS: Retrospective, observational study. Electronic medical records and images of patients with endometrioma who underwent CDS from August 2014 to April 2022 at a single institution were obtained. Patients aged > 18 years old and with anti-Müllerian hormone (AMH) level between 0.8 and 10.0 with regular menstruation were enrolled. Cyst diameter, laterality, AMH level, and CA-125 level before and after 1 month, 6 months, 1 year, 2 years, and 3 years of sclerotherapy were obtained. RESULTS: A total of 180 patients were fit for analysis. There was no statistical difference in age and cyst size between the two groups. Mean values of AMH in each group were 3.35 in the primary group and 3.00 in the recurrent group prior to the procedure (p = 0.347). There was no significant difference in delta value of AMH after sclerotherapy in both groups at each follow-up period. Also, this result was consistent when stratified by laterality, preprocedural AMH level, and initial size of endometrioma. No case of recurrence was reported in both groups. CONCLUSIONS: The effect of CDS on ovarian reserve is not inferior in recurrent endometrioma compared to primary endometrioma. Since sclerotherapy is known to less deteriorate the ovarian function than surgical removal of endometrioma, clinician could consider this as the first-line therapy in patients with recurrent endometrioma. CLINICAL RELEVANCE STATEMENT: Catheter-directed ethanol sclerotherapy for patients with recurrent endometrioma has similar effect on ovarian reserve compared to patients with primary endometrioma. KEY POINTS: • Secondary surgery for endometrioma has significant deleterious effect on ovarian function. • Catheter-directed sclerotherapy (CDS) for endometrioma had equally minimal adverse effect on ovarian reserve, represented as anti-Müllerian hormone (AMH), in both primary and recurrent groups. • Physicians should consider CDS for patients with recurrent endometrioma who desire to preserve ovarian function.

A Systematic Review Network Meta-Analysis and Meta-Regression on Surgical and Endovenous Interventions for the Treatment of Lower Limb Venous Ulcer Disease.

BACKGROUND: Venous leg ulcer (VLU) disease constitutes the most severe form of chronic venous insufficiency. We performed a network meta-analysis and meta-regression to investigate the efficacy and safety of the various available interventions in the treatment of VLU. METHODS: We conducted a systematic research corresponding to the instructions by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement for studies reporting on surgical or endovenous interventions for the treatment of VLU. Following data extraction, we performed a Bayesian network meta-analysis and meta-regression. Primary endpoints included VLU healing and recurrence. The secondary endpoint was postintervention complications. RESULTS: Seventeen studies evaluating the impact of compression monotherapy, radiofrequency ablation (RFA), endovenous laser ablation (EVLA), sclerotherapy, and saphenous vein surgery on VLU treatment, consisting of 2156 patients (2186 VLU) were included. When compared to compression monotherapy, RFA was the only treatment displaying a statistically-significant impact on ulcer healing, odds ratio (OR) 5.80 (95% credibility interval (CI): 1.08-35.07), while EVLA, RR 0.06 (95% CI: 0.00-0.57), sclerotherapy, RR 0.07 (95% CI: 0.00-0.68) and RFA, RR 0.12 (95% CI: 0.01-0.91) were the 3 interventions reducing VLU recurrence. EVLA (SUCRA, 69.65) ranked as the most efficient intervention concerning ulcer recurrence reduction. Regarding postintervention complications, EVLA was the only intervention displaying a statistically-significant increased risk compared to compression monotherapy, RR 14.3 (95% CI: 2.03-172.56). Meta-regression analysis exploring the impact of perforator treatment on VLU failed to predict healing, ß = -0.27 (95% CI: -2.55 to 1.85), recurrence, ß = -0.02 (95% CI: -2.96 to 2.75) and complication outcomes, ß = -0.089 (95% CI: -3.13 to 2.85). During sensitivity analysis, RFA and sclerotherapy failed to sustain their effects on ulcer healing and ulcer recurrence, respectively. In addition, sclerotherapy displayed statistically-significant inferior outcomes compared to both EVLA and RFA regarding ulcer recurrence. CONCLUSION: This is the first network meta-analysis examining the effect of various interventions on VLU disease. While we have demonstrated the efficacy of RFA and ELVA in ulcer recurrence prevention, our results regarding the impact of RFA and sclerotherapy on VLU healing and recurrence, respectively, should be interpreted with caution. In addition, this review raises questions concerning the value of surgery and perforator interventions in the treatment of VLU. Further research through randomized controlled trials is required. CLINICAL IMPACT: Our review has revealed the significant efficacy of endovenous laser ablation (EVLA) and radiofrequency ablation (RFA) in effectively reducing the incidence of ulcer recurrence when compared to compression monotherapy. These outcomes hold the potential to provide relevant insights to both medical practitioners and patients, thereby informing a more prudent and enlightened decision-making approach. Such informed decisions, aimed at mitigating the recurring occurrence of venous leg ulcers, carry profound significance given the considerable socioeconomic implications associated with this medical condition.
