Outcomes of endoscopic sclerotherapy for jejunal varices at the site of choledochojejunostomy (with video): Three case reports.

BACKGROUND: Hemorrhage associated with varices at the site of choledochojejunostomy is an unusual, difficult to treat, and often fatal manifestation of portal hypertension. So far, no treatment guidelines have been established. CASE SUMMARY: We reported three patients with jejunal varices at the site of choledochojejunostomy managed by endoscopic sclerotherapy with lauromacrogol/α-butyl cyanoacrylate injection at our institution between June 2021 and August 2023. We reviewed all patient records, clinical presentation, endoscopic findings and treatment, outcomes and follow-up. Three patients who underwent pancreaticoduodenectomy with a Whipple anastomosis were examined using conventional upper gastrointestinal endoscopy for suspected hemorrhage from the afferent jejunal loop. Varices with stigmata of recent hemorrhage or active hemorrhage were observed around the choledochojejunostomy site in all three patients. Endoscopic injection of lauromacrogol/α-butyl cyanoacrylate was carried out at jejunal varices for all three patients. The bleeding ceased and patency was observed for 26 and 2 months in two patients. In one patient with multiorgan failure and internal environment disturbance, rebleeding occurred 1 month after endoscopic sclerotherapy, and despite a second endoscopic sclerotherapy, repeated episodes of bleeding and multiorgan failure resulted in eventual death. CONCLUSION: We conclude that endoscopic sclerotherapy with lauromacrogol/α-butyl cyanoacrylate injection can be an easy, effective, safe and low-cost treatment option for jejunal varicose bleeding at the site of choledochojejunostomy.

Effect of lidocaine on postoperative analgesia of endoscopic rubber band ligation combined with injection sclerotherapy for treatment of internal hemorrhoids: A retrospective study (with video).

BACKGROUND AND STUDY AIMS: Endoscopic minimally invasive treatment of internal hemorrhoids may cause postoperative pain. The aim of the study is to investigate the analgesic effect of lidocaine plus lauromacrogol on postoperative pain caused by endoscopic rubber band ligation (ERBL) combined with injection sclerotherapy (IS) for internal hemorrhoids treatment. PATIENTS AND METHODS: Clinical data of grade Ⅲ internal hemorrhoids patients who underwent ERBL combined with IS in department of Digestive Medicine, Shenzhen Hospital of Southern Medical University, were retrospectively analyzed. According to difference in the composition of sclerosing solution, the patients were divided into control group (lauromacrogol group, 46 patients) and study group (lidocaine plus lauromacrogol group, 20 patients). Postoperative pain (quantized by Visual Analogue Scale, VAS), pain relief time and postoperative adverse reactions were compared. The therapeutic effect was followed up 1 month after operation. RESULTS: VAS of postoperative pain was 0.80 ± 0.42 points and pain relief time was 0.90 ± 0.56 days in the study group, while VAS of postoperative pain was 4.11 ± 1.37 points and pain relief time was 2.57 ± 0.83 days in the control group, there was statistical difference between them (P < 0.05). There was no significant difference in the incidence of postoperative adverse reactions and follow-up therapeutic effect between the control group and the study group. CONCLUSION: Lidocaine plus lauromacrogol is useful for pain alleviation on ERBL combined with IS for internal hemorrhoids treatment because of its convenient procedure, low adverse reaction incidence and good therapeutic effect, which is worthy of promotion.

Efficacy of Bleomycin-Lauromacrogol Foam in Pediatric Macrocystic Lymphatic Malformations With and Without Intracapsular Hemorrhage.

BACKGROUND: Sclerotherapy is purportedly less effective in patients with hemorrhagic than with non-hemorrhagic lymphatic malformations (LMs). We aimed to compare the efficacy of bleomycin-lauromacrogol foam (BLF) sclerotherapy in the treatment of macrocystic LMs with and without intralesional hemorrhage. METHODS: Fifty-five children with macrocystic LMs admitted to the Pediatric Surgery Department were retrospectively included. The patients were allocated into a hemorrhage group (23 cases) or a non-hemorrhage group (32 cases) based on the occurrence of an intracapsular hemorrhage. The diagnosis was confirmed by physical examination, color ultrasound, magnetic resonance imaging, and puncture findings. BLF was injected into the capsule after draining the cystic fluid under color ultrasound guidance. Patients whose lesions were unchanged or showed minor change after 1 month were treated again using the same method. Changes in lesion size and the number of treatments were recorded. Effectiveness was classified as excellent (volume reduction ≥90%), good (50%≤volume reduction<90%), or poor (volume reduction <50%). RESULTS: In the hemorrhage group, 17, 6, and 0 patients' outcomes were classified as excellent, good, and poor, respectively. The overall efficacy rate was 100%. In the non-hemorrhage group, 23, 7, and 2 patients' outcomes were classified as excellent, good, and poor, respectively. The overall efficacy rate was 93.8%. There was no significant difference in efficacy rate between groups (P = 0.767). CONCLUSIONS: BLF is an effective and safe treatment for macrocystic LMs with bleeding. The results were similar in patients with and without bleeding. LEVEL OF EVIDENCE: Treatment, Level III.

Foam Sclerotherapy in the Treatment of Hemangiomas and Venous Malformations.

BACKGROUND: Sclerotherapy has achieved great success in treating most venous malformation (VM) lesions. OBJECTIVE: To compare the effects of foam sclerotherapy on infantile hemangioma and pyogenic granuloma (PG). In addition, we analyzed the data and outcomes of foam sclerotherapy for the VM. MATERIALS AND METHODS: Thirty-nine patients with hemangiomas and 83 patients with VMs were treated, and clinical outcomes, resolution, and complication rates were compared. Sclerotherapy data from the VM group were also analyzed. RESULTS: The average age of the patients and the distribution and tissue involvement of lesions among the 3 groups were significantly different ( p < .001). The average amount of sclerosing foam administered per session in VMs was significantly higher than that in the other 2 groups ( p < .0001) (whereas that in the PG group was lower than that in the infantile hemangioma group [ p < .0001]). However, the overall therapeutic efficacy and side effects in the 3 groups were not significantly different. For VMs, the frequency of ultrasound guided foam sclerotherapy and use of 3% polidocanol increased from superficial to deep lesions, whereas the use of 1% POL decreased ( p < .0001). CONCLUSION: Infantile hemangioma and PG treatments presented good results and minor adverse reactions comparable with those of VMs.

HEmoRhoidal disease management with Band ligation versus polidocanol Sclerotherapy: a systematic review and meta-analysis (the HerBS Review).

PURPOSE: Symptomatic internal hemorrhoids affect up to 40% of people in Western society. Patients with grade I-III hemorrhoids, who fail lifestyle and medical management, may benefit from office-based procedures. As per the American Society of Colon and Rectum Surgeons (ASCRS), rubber band ligation (RBL) is the first-line office-based treatment. Polidocanol sclerotherapy is a relatively new approach for these patients. The aim of this systematic review is to compare the efficacy of RBL and polidocanol sclerotherapy with the treatment of symptomatic grade I-III internal hemorrhoids. METHODS: The systematic review was completed by searching MEDLINE, Embase, and CENTRAL databases from inception to August 2022 for prospective studies comparing RBL and polidocanol sclerotherapy or evaluating the efficacy of polidocanol sclerotherapy alone for adult (> 18 years) patients with grade I-III internal hemorrhoids. Treatments were evaluated for therapeutic success and post-procedure morbidity. RESULTS: Of 155 citations obtained, 10 studies (3 comparative and 7 single-arm studies) and 4 abstracts (2 comparative and 2 single arm) were included in the study. The patients undergoing sclerotherapy had a 93% (151/163) therapeutic success rate compared to 75% (68/91) in the RBL group (OR 3.39, 95% CI 1.48-7.74, p < 0.01). The post-procedure morbidity was 8% (17/200) in the sclerotherapy group and 18% (23/128) in the RBL group (OR 0.53, 95% CI 0.15-1.82, p = 0.31). CONCLUSION: This study highlights that polidocanol sclerotherapy may be associated with higher therapeutic success in patients with symptomatic grade I-III internal hemorrhoids. Further evaluations in the form of randomized trials are required to evaluate patient populations, which may benefit more from sclerotherapy.

Value of fat-suppressed T2-weighted imaging for predicting short-term pain relief after sclerotherapy for venous malformations in the extremities.

PURPOSE: This study aimed to evaluate the value of fat-suppressed T2-weighted imaging (FS-T2WI) for predicting short-term pain relief after polidocanol sclerotherapy for painful venous malformations (VMs) in the extremities. MATERIALS AND METHODS: This retrospective study included patients with painful VMs in the extremities between October 2014 and September 2021, had their first sclerotherapy without history of surgical therapy, and underwent magnetic resonance imaging before sclerotherapy. Pain relief was assessed 2 months after 3% polidocanol sclerotherapy and was categorized as follows: progression, no change, partial relief, or free of pain. The associations between pain relief and imaging features on FS-T2WI were analyzed. RESULTS: The study included 51 patients. The no change, partial relief, and free of pain groups included 6 (11.8%), 25 (49.0%), and 20 (39.2%) patients, respectively. No patient experienced progressive pain. The lesion diameter was ≤ 50 mm in 13 (65.0%) patients in the free of pain group, whereas it was > 50 mm in all patients in the no change group (p = 0.019). The lesions showed well-defined margin in 15 (75.0%) patients in the free of pain group, whereas they showed ill-defined margin in 5 (83.3%) patients in the no change group (p = 0.034). The most common morphological type was cavitary in the free of pain group (14 [70.0%] patients), whereas there was no patient with cavitary type lesion in the no change group (p = 0.003). Drainage vein was demonstrated in 6 (100%), 22 (88.0%), and 11 (55.0%) patients in the no change, partial relief, and free of pain group, respectively (p = 0.011). CONCLUSION: A lesion size of 50 mm or less, a well-defined margin, a cavitary type, and no drainage vein on FS-T2WI were significant features for predicting short-term pain relief after polidocanol sclerotherapy for painful VMs in the extremities.

Predictive factors analysis of cesarean scar pregnancy treated by local injection of Lauromacrogol combined with curettage.

To explore factors related to local injection of Lauromacrogol combined with curettage in the treatment of cesarean scar pregnancy. A total of 24 successful and 8 unsuccessful cases were included. The age, gravidity, parity, times of cesarean section, interval from the last cesarean section, preoperative human chorionic gonadotropin (HCG), HCG on the first day after operation, decreasing rate of HCG on the first day after operation, average diameter of gestational sac, and preoperative vaginal bleeding days were analyzed. There were no significant differences of age, gravidity, parity, previous cesarean section times between groups. The differences of preoperative HCG, HCG on the first day after operation, the decreasing rate of HCG, gestational sac diameter, preoperative vaginal bleeding days were statistically significant between groups. The interval from the last cesarean section and the decreasing rate of HCG were protective factors, while the mean diameter of gestational sac and period of vaginal bleeding before operation were risk factors for the success of the treatment. The mean diameter of gestational sac owned the best predictive value.

3% polidocanol foam sclerotherapy versus hemorrhoidal artery ligation with recto anal repair in hemorrhoidal disease grades II-III: a randomized, pilot trial.

PURPOSE: Polidocanol foam sclerotherapy (SP) versus doppler-guided hemorrhoidal artery ligation with recto-anal repair (HAL-RAR) in the treatment of hemorrhoidal disease (HD) was analyzed. METHODS: A prospective, randomized study including patients with HD grades II and III was performed. Participants were randomly assigned (1:1) into SP or HAL-RAR, during a recruitment period between September 2019 and February 2020. Therapeutic success (Sodergren's and bleeding scores) was the primary outcome. Other outcomes evaluated included complications and implication in the professional life. Efficacy and safety outcomes were evaluated during the 8 weeks after surgery or the final SP session. RESULTS: Forty-six patients were allocated either to SP (n=22) or HAL-RAR (n=24). Most patients achieved therapeutic success (SP 100% vs. HAL-RAR 90.9%, p=0.131). Complete success was higher in the SP group (91.7% vs. 68.2%, p=0.045) and SP patients had less complications (25% vs. 68.2%, p=0.003). HAL-RAR had a greater negative impact on work activity of the patient. CONCLUSION: SP was more effective and safer than HAL-RAR. SP patients had less impact on their work activity. Clinical trials identifier NCT04675177.

Single Center Experience of Percutaneous Septal Ablation in Patients With Hypertrophic Cardiomyopathy With A Novel Agent: Polidocanol.

Septal reduction therapy is recommended in patients with obstructive hypertrophic cardiomyopathy (HCM) who remain symptomatic under maximally tolerated optimal medical treatment. Alcohol septal ablation is a favorable option, especially in patients with high surgical risk or who refuse surgery. Alcohol; causes scar-related ventricular arrhythmias and advanced heart blocks more frequently than surgical myectomy. Therefore, novel, safer agents are required for percutaneous septal ablation therapy. All the patients who underwent percutaneous septal ablation between January 2017 and June 2021 with polidocanol because of ongoing symptoms related to HCM despite maximally tolerated medical treatment were enrolled. Data were obtained retrospectively from the hospital electronic database. A total of 28 patients were included. Median age was 61 years (43.5-67), and 19 (67.8%) patients were male. Most of the patients underwent index procedures; however, only 2 cases had history of previous septal ablation. Median follow-up was 3.5 months (0.25 to 12.25). Median left ventricular outflow tract (LVOT) gradient at rest was 68.5 (37-80) mm Hg, and after Valsalva maneuver median LVOT gradient was 95.5 (75-125) mm Hg. Median volume of polidocanol used in procedures was 2 (2-3.37) ml, and mean procedure time was 28.1 ± 2.5 minutes. LVOT gradient invasively measured was significantly reduced (mean 76.5 mm Hg vs mean 30 mm Hg; p <0.001) immediately after the septal ablation. Conduction defects developed in 18 patients (64.2%); however, de novo permanent cardiac implantable electronic device implantation was required in only 4 (14.3%) cases. Leakage of polidocanol and mortality did not occur in any cases. Pericardial effusion developed in only 1 case, and it resolved with medical treatment. After mean 3.5 months follow-up, both LVOT gradient and New York Heart Association functional class parameters were better than baseline values. In conclusion, polidocanol is a safe and effective agent for septal ablation in patients with HCM. Outcomes and complication rates are similar with alcohol septal ablation.

Effectiveness and safety of percutaneous sclerotherapy using absolute ethanol and/or polidocanol for maxillofacial venous malformations involving the masticatory muscles: A case series.

OBJECTIVE: This study evaluated the effectiveness and safety of percutaneous sclerotherapy for maxillofacial venous malformations. STUDY DESIGN: Patients who had venous malformations involving the masticatory muscles and who underwent sclerotherapy were enrolled in this retrospective study. RESULTS: Twenty-four patients (13 female, 11 male; mean age 21 years) were analyzed. Major clinical symptoms were swelling (100%) and intralesional pain (54%). Intramuscular lesions involved the masseter muscle only in 38% of cases, both the masseter and temporalis muscles in 33%, all masticatory muscles in 21%, and the temporalis muscle only in 8%. Extramuscular involvement was observed in 58% of patients. Absolute ethanol and polidocanol were used as sclerosants. The mean number of sclerotherapy sessions per patient was 6.6 (range, 1-32). The mean follow-up duration after the first sclerotherapy session was 64.8 months (range, 6-178). The complications included paralysis of the facial nerve (25%), intraoral ulceration (8%), and hemoglobinuria (8%). The effectiveness of treatment was rated as excellent in 33% of cases, good in 46%, and fair in 21%. Better results were obtained in patients without extramuscular involvement. CONCLUSION: Percutaneous sclerotherapy can be effective and safe for maxillofacial intramuscular venous malformations, especially for localized lesions of the masseter muscle.

Sclerotherapy with 3% polidocanol foam to treat second-degree haemorrhoidal disease: Three-year follow-up of a multicentre, single arm, IDEAL phase 2b trial.

BACKGROUND: Sclerotherapy with 3% polidocanol foam is becoming increasingly popular for the treatment of symptomatic I-II or III degree haemorrhoidal disease (HD). However, there are no studies that have reported a follow-up of more than 1 year. The purpose of this study was to analyse the long-term outcomes of sclerotherapy with 3% polidocanol foam in the treatment of II-degree HD. METHODS: This was an open label, single-arm, phase 2b trial conducted in 10 tertiary referral centres for HD. A total of 183 patients with II-degree HD, aged between 18 and 75 years with symptomatic HD according to the Goligher classification and unresponsive to medical treatment, were included in the study and underwent sclerotherapy with 3% polidocanol foam. The efficacy was evaluated in terms of bleeding score, haemorrhoidal disease symptom score (HDSS) and short health scale for HD (SHS-HD) score. Successful treatment was defined as the complete absence of bleeding episodes after 7 days (T1) according to the bleeding score. RESULTS: The overall success rate ranged from 95.6% (175/183) at 1 year to 90.2% (165/183) after the final 3 year follow-up. The recurrence rate, based on the primary outcome, ranged from 12% (15/125) to 28% (35/125). The greatest increase in recurrence (15) was recorded between 12 and 18 months of follow-up, then another five between 18 and 24 months. Both the HDSS and the SHS score remained statistically significant (p < 0.001) from a median preoperative value of 11 (10-13) and 18 (15-20) to 0 (0-2) and 4 (0-4), respectively. Symptom-free (HDSS = 0) patients, excluding patients converted to surgery, increased from 55.5% (101/182) at 1 year to 65.1% at 3 years (110/169). There were no intraoperative complications in redo-sclerotherapy nor additional adverse events (AEs) compared to the first 12 months. CONCLUSIONS: Sclerotherapy with 3% polidocanol foam is gradually establishing itself in the treatment of bleeding HD due to its repeatability, safety, convenience in terms of direct and indirect costs with the absence of discomfort for the patient as well as AEs rather than an excellent overall success rate.

A single-center, single-arm, prospective, open-label trial to evaluate the efficacy and safety of percutaneous sclerotherapy with polidocanol for painful venous malformations (SCIRO-2001): study protocol.

This single-center, single-arm, prospective open-label trial is being conducted to evaluate the short-term efficacy and safety of percutaneous sclerotherapy with polidocanol foam for painful venous malformations. This study will include patients who were clinically diagnosed with venous malformation by using ultrasound and/or magnetic resonance imaging, and whose pain persisted even after treatment with medications. Written informed consent for sclerotherapy will be obtained from all patients. The institutional review board approved this prospective study protocol. The primary endpoint is pain relief at three months after sclerotherapy. Local pain related to venous malformation will be evaluated using a numeric rating scale. Patient recruitment commenced in December of 2020. Enrolment of 13 patients is planned over a 3-year recruitment period. Herein, we describe the details of the clinical trial protocol.

Polidocanol: A Review of Off-Label Dermatologic Uses.

BACKGROUND: Polidocanol is an FDA-approved treatment of incompetent great saphenous veins, accessory saphenous veins, and visible varicosities of the great saphenous vein system, but numerous other off-label dermatological applications have been reported. OBJECTIVE: To describe the various off-label dermatological clinical uses of polidocanol, as well as efficacy and adverse effects. METHODS: The review of studies searchable on PubMed from 2004 to 2021 describing clinical uses of polidocanol to determine efficacy and adverse effects associated with various dermatologic applications. RESULTS: Polidocanol has shown efficacy in the treatment of mucocele of minor salivary gland, hemangioma, upper extremity veins, reticular veins of the chest, facial veins, pyogenic granuloma, lymphangioma circumscriptum, digital mucous cyst, mixed skin ulcers, cutaneous focal mucinosis, seromas, glomuvenous malformations, acne cysts, lymphocele, and dissecting cellulitis. Commonly reported side effects include pain, erythema, swelling, ecchymosis, and ulceration. Most sources were case reports and small prospective studies, as such the strength of data supporting many uses is limited by small sample sizes and lack of controls. CONCLUSION: Although polidocanol is currently only FDA approved for incompetent great saphenous veins, accessory saphenous veins, and visible varicosities of the great saphenous vein system, the use of polidocanol has been selected for a variety of off-label clinical applications.

Polidocanol monotherapy for a superficial orbital venous malformation in a horse.

OBJECTIVE: To describe the use of 1% polidocanol as the sole treatment for a superficial orbital venous malformation in a horse. ANIMAL: A 23-year-old Welsh Cobb cross gelding with a distensible swelling affecting the left lower eyelid, and secondary palpebral margin abnormalities and superficial keratitis. PROCEDURE: Color flow Doppler ultrasonography revealed non-pulsatile blood flow within the tortuous vascular network most consistent with a superficial orbital venous malformation appearing to involve the lateral palpebral and transverse facial veins. An intravenous catheter was placed within the lateral aspect of the venous malformation, and agitated saline was slowly injected into the vessel while simultaneously ultrasound imaging the medial aspect in which the bubbles were observed coursing across, consistent with lateral to medial flow. Contrast venography confirmed a corkscrew vessel along the ventral aspect of the orbital rim. Under standing sedation, 1% polidocanol solution was administered slowly through the intravenous catheter while manual pressure was applied on the medial and lateral aspects of the venous malformation. RESULTS: Ultrasonography performed immediately after administration of polidocanol confirmed venous stasis, and formation of a thrombus. No adverse side effects were noted. The venous malformation and associated palpebral margin abnormalities and superficial keratitis resolved at the time of re-examination at 4 months. CONCLUSION AND CLINICAL RELEVANCE: Polidocanol as the sole treatment for a superficial orbital venous malformation in a horse was well tolerated and led to clinical resolution. Sclerosant monotherapy may be a safe treatment option for superficial orbital venous malformations.

Successful Sclerotherapy for Cervicofacial Macrocystic Lymphatic Malformations Using Polidocanol and Pingyangmycin Combined Foam Sclerosants.

Background: Sclerotherapy is the first-line therapeutic method for lymphatic malformations (LMs). This retrospective cohort study evaluated the effectiveness and safety of a novel combined foam sclerosant: polidocanol and pingyangmycin foam (PPF), for treating cervicofacial macrocystic LMs. Methods and Results: From July 2018 to October 2020, 51 patients with cervicofacial macrocystic LMs were enrolled in this study. All patients received intralesional 3% polidocanol or PPF injections. The outcome was evaluated regarding demographic and clinical characteristics, degree of treatment response, and post-treatment complications. Overall, 16 patients (31.4%) underwent PPF sclerotherapy. All these patients (100%) showed remarkable reduction in lesion size within three sessions. Excellent responses were shown in 88.5% of these patients within three sessions, which is higher than single polidocanol sclerotherapy (80%). The average sessions (duration) of PPF sclerotherapy were 2.5, which was significantly shorter than the single foam sclerotherapy (p < 0.05). Treatment duration was significantly associated with age, lesion location, lesion size, and number of cysts (p < 0.05). No severe complications were noted in this study. Local or systemic complications, such as swelling and mild fever occurred but subsided without any specific treatment. Conclusions: PPF is a safe, and effective combined foam sclerosant for the treatment of cervicofacial macrocystic LMs. This combined foam can improve treatment response and reduce treatment duration compared with a single sclerosant. It can be broadly used if further large-scale clinical trials verify its efficacy and safety.
