Efficacy and security of lauromacrogol and pingyangmycin in treatment of hemangioma and venous malformation: A meta-analysis / 解放军医学杂志

Objective: To systematically evaluate the clinical efficacy and safety of pingyangmycin and lauromacrogol in treatment of hemangioma or venous malformation. Methods: All the databases of PubMed, Cochrane Library, Embase, Web of Science, Wanfang, CBM, VIP and CNKI were searched from their inception to November 30, 2018 to seek the randomly controlled trials (RCTs) involving the efficacy and adverse reaction of lauromacrogol and pingyangmycin in treatment of hemangioma and venous malformation. According to the inclusion and exclusion criteria, two reviewers were respectively responsible for screening researches, extracting data and assessing the risk of bias of included studies. Subsequently, meta-analysis was performed with RevMan 5.3 software. Results: A total of 12 studies containing 1619 individuals with hemangioma or venous malformation were incorporated. Meta analysis showed that the cured rates of hemangioma and venous malformation were superior when treated with lauromacrogol than with pingyangmycin, the difference was statistically significant (OR=1.98, 95%CI 1.58-2.49, P<0.001). While no significant difference existed in the efficiency (OR=1.17, 95%CI 0.40-3.41, P=0.77) and inefficiency (OR=0.44, 95%CI 0.12-1.66, P=0.23) when treating hemangioma and venous malformation with lauromacrogol or pingyangmycin. The incidence of complication was distinctly lower in lauromacrogol group than in pingyangmycin group with statistical significance (OR=0.27, 95%CI 0.17-0.44, P<0.001). Conclusion: In the treatment of hemangioma and venous malformation, lauromacrogol is obviously superior to pingyangmycin in the therapeutic effect and safety, but there is no significant difference in effectively reducing the focus.

Therapeutic effect of pingyangmycin injection combined with hypercator resection under suspension laryngoscope on laryngopharyngeal hemangioma / 第二军医大学学报

Objective To observe the clinical effect of pingyangmycin injection combined with hypercator resection on laryngopharyngeal and laryngeal hemangioma under suspension laryngoscope. Methods Twenty-seven patients with laryngopharyngeal or laryngeal hemangioma were included. After trachea cannula via mouth and general anesthesia, the suspension laryngoscope was used to completely uncover the hemangioma, and 8 mg pingyangmycin (diluted with 6 mL saline injection) was locally injected into the tumor. And then the tumor was completely resected along its root by polypus forceps-like hypercator or was completely coagulated by electric coagulation. The intra-operative and post-operative bleeding were recorded, and the patients were given liquid diets after surgery for two weeks. The fibrolaryngoscope was reviewed to judge the curative effect at 1 month, 3 months, 1 year, 2 years, and 3 years after surgery. Results The pink or prunosus tumor turned into pinkish-white tumor after injection of pingyangmycin. When the root pedicle of the tumor was revealed by forceps holder, the polypus forceps-like hypercator could completely resect the tumor along the base of root, nearly without bleeding in the operation; when the root pedicle was big or could not be revealed, the tumor could be completely coagulated by electric coagulation. After surgery, no patients had dyspnea or wound bleeding. One month later, fibrolaryngoscope showed that the wound was repaired with pink normal mucosa. No recurrence was found in all cases after follow-up for 1 year. After 2 years of follow-up, one case had flaky purple uplift of the pharyngeal wall mucosa, and the tumor was completely resected by the above treatment. No recurrence was found after 3 years of follow-up. Conclusion Hypercator resection after local injection of pingyangmycin under suspension laryngoscope can completely resect the lesions, with less surgery trauma and quick recovery, suggesting that the treatment has affirmative efficacy and is worth popularizing.

Diagnosis and treatment of infantile congenital subglottic hemangioma / 临床耳鼻咽喉头颈外科杂志

Objective: To discuss the diagnosis and treatment of infantile congenital subglottic hemangioma. Method:Nine patients with recurrent stridor,feeding difficulties and laryngeal obstruction were diagnosed as con-genital subglottic hemangioma with bronchia endoscopy. The lesions were unilateral in 7 cases and bilateral in 2 ca-ses. Eight cases were treated by intralesional Pingyangmycin injection after tracheotomy. Patients were discharged with metal trachea and were followed up endoscopically 2 weeks thereafter. A second treatment would be required if the tumor reduced in size but not disappeared completely. Plugging tubes and extubation would be done when the tumor disappeared completely. One case with unilateral lesion underwent power-assisted tumor resection with-out tracheotomy. Result: Hemangioma vanished completely in 6 patients with unilateral subglottic hemangioma who were treated with single stage procedure. Tumor size was found reduced significantly after one procedure and van-ished completely after a second procedure in 2 cases with bilateral subglottic hemangioma. All of the 8 cases were extubated successfully. The patient recovered thoroughly in two weeks after power-assisted tumor resection. Con-clusion: Intralesional Pingyangmycin injection after tracheotomy can relief the airway obstruction quickly, shorten the nature course of hemangioma, shorten the period of wearing trachea, has no complication such as subglottic stenosis and is thought to be a safe and effective therapy for large size hemangioma. Power-assisted tumor resec-tion under good total anesthesia without tracheotomy combined with well hemostasis is effective, less injure, and suitable for small size hemangioma.
