IntroductionTo investigate the therapeutic effect of clitoris exposure + episioplasty + dermabrasion + platelet-rich plasma (PRP) injection + chemexfoliation on vulvar lichen sclerosus (VLS).MethodsTwenty children with VLS (under 14 years old) at our hospital from July 2020 to November 2022 were enrolled and treated with clitoris exposure + episioplasty + dermabrasion + PRP injection + chemexfoliation. Additionally, symptomatic changes and improvements in signs were recorded.ResultsSignificant therapeutic effects were achieved in all children enrolled in this study. The Cattanco score was 8.02 ± 1.22 points before surgery, 2.21 ± 0.70 points 3 months after surgery, and 2.61 ± 0.59 points 6 months after surgery, demonstrating that the score after surgery was significantly lower than that before surgery (p < 0.05). Mild complications (one case of mild vulvar swelling, one case of minor bleeding, and one case of superficial ulcer) were observed in three children after surgery, with an overall complication incidence of 15%; all complications were improved after the intervention, and no severe adverse reactions were observed. Recurrence was observed in one child (5%) 6 months after surgery.ConclusionClitoris exposure + episioplasty + dermabrasion + PRP injection + chemexfoliation is an effective approach for the treatment of VLS.Systematic Review Registrationhttps://www.chictr.org.cn/searchproj.html, identifier: ChiCTR2100054787.

BackgroundCongenital Morgagni hernia (CMH) is a rare midline defect involving herniation of abdominal viscera into the thoracic cavity through triangular parasternal gaps in the diaphragm.MethodsThe medical records of three patients with CMH admitted to the Department of Pediatric Surgery at the Affiliated Hospital of Zunyi Medical University between 2018 and 2022 were retrospectively reviewed. Pre-operative diagnosis was based on chest x-ray, chest computerized tomography, and barium enema. All patients were treated with single-site laparoscopic ligation of the hernia sac.ResultsHernia repair was successful in all patients (males; age: 14 months, 30 months, 48 months). The average operative time for repair of a unilateral hernia was 20 ± 5 min. Volume of surgical blood loss was 2–3 ml. There was no damage to organs such as the liver or intestines, or to tissues such as the pericardium or the phrenic nerve. Patients were allowed a fluid diet 6–8 h after surgery, and remained on bed rest until 16 h after surgery. No postoperative complications occurred, and patients were discharged on postoperative Day 2 or 3. No symptoms or complications were noted during the 1–48 months of follow-up. Aesthetic outcomes were satisfactory.ConclusionsSingle-site laparoscopic ligation of the hernia sac provides pediatric surgeons a safe and effective technique for repair of CMH in infants and children. The procedure is straightforward, operative time and surgical blood loss are minimal, recurrence is unlikely, and aesthetic outcomes are satisfactory.
