Endometriosis is defined as the presence and growth of the glands and stroma of the lining of the uterus in an aberrant or heterotopic location. The cause of endometriosis is uncertain and involves many mechanisms including retrograde menstruation, vascular dissemination, metaplasia, immunologic, and hormonal influences to name a few. Primary umbilical endometriosis is a rare disorder defined as the presence of ectopic endometrial tissue within the umbilicus. It commonly presents with catamenial pain and bleeding from an umbilical nodule. It is a rare condition and treatment has not been standardized yet due to the limited number of cases. Surgical management is the treatment of choice to avoid local recurrence while hormone therapy may be used preoperatively for symptomatic relief. This paper reports a series of recently observed cases of primary umbilical endometriosis with main aim of discussing the different approaches in the management of this rare condition.

Gliomatosis peritonei (GP) is a condition characterized by the dissemination of mature glial tissues throughout the peritoneal cavity. It is usually associated with immature ovarian teratoma but presents with mature cystic teratoma (MCT) in 1% of cases. GP, associated with MCT, is a benign disorder. The majority of cases remain asymptomatic and rarely recur. Here, we present a case of a 22-year-old woman with a history of abdominal enlargement and severe abdominal pain who underwent exploratory laparotomy, peritoneal fluid cytology, bilateral salpingo-oophorectomy, appendectomy, omental biopsy, and Jackson-Pratt drain insertion with histopathologic result of GP with MCT. A month later, the patient had a recurrence of abdominal enlargement, necessitating a second surgery. Immunohistochemistry for histopathologic evaluation and diagnostic imaging are crucial in confirming the diagnosis and guiding the treatment strategy. A multidisciplinary team approach in monitoring and comprehensive support is significant in optimizing outcomes for patients with aggressive GPs associated with MCT. Further research and clinical experience are essential to establish a standardized guideline to improve the management and clinical outcome of this condition.

This study aims to develop an abdominal acupoint localization system based on computer vision and convolutional neural networks (CNNs). To address the challenge of abdominal acupoint localization, a multi-task CNNs architecture was constructed and trained to locate the Shenque (CV8) and human body boundaries. Based on the identified Shenque (CV8), the system further deduces key characteristics of four acupoints: Shangwan (CV13), Qugu (CV2), and bilateral Daheng (SP15). An affine transformation matrix is applied to accurately map image coordinates to an acupoint template space, achieving precise localization of abdominal acupoints. Testing has verified that this system can accurately identify and locate abdominal acupoints in images. The development of this localization system provides technical support for TCM remote education, diagnostic assistance, and advanced TCM equipment, such as intelligent acupuncture robots, facilitating the standardization and intelligent advancement of acupuncture.

OBJECTIVE: To explore the effectiveness of free paraumbilical perforator flaps in repairing skin and soft tissue defects in children. METHODS: Between February 2018 and March 2024, 12 children with skin and soft tissue defects were treated with the free paraumbilical perforator flaps. There were 7 boys and 5 girls with an average age of 6.3 years (range, 2-12 years). The defects located on the upper limbs in 6 cases, lower limbs in 5 cases, and neck in 1 case. The causes of wounds included 7 cases of electrical burns, 1 case of thermal burn, 2 cases of scar release and excision due to scar contraction after burns, 1 case of scar ulcer at the amputation stump after severe burns, and 1 case of skin necrosis after a traffic accident injury. The size of defects after debridement ranged from 7.0 cm×4.0 cm to 18.0 cm×10.0 cm. According to the defect size, 11 cases were repaired with unilateral paraumbilical perforator flaps centered on the umbilicus, among which 3 cases with larger defects were designed as "L"-shaped flaps along the lateral and lower ends of the perforator; the donor sites were directly closed. One case with extensive defect after scar excision and release was repaired with bilateral expanded paraumbilical perforator flaps; the donor sites were repaired with autologous split-thickness skin grafts. The size of flaps ranged from 9.0 cm×4.0 cm to 20.0 cm×11.0 cm. Postoperatively, analgesia and sedation were provided, and the blood supply of the flaps was observed. RESULTS: All operations were successfully completed. The operation time was 4-7 hours, with an average of 5.0 hours. After postoperative analgesia and sedation, the visual analogue scale (VAS) score for pain in all children was less than or equal to 3, and there was no non-cooperation due to pain. All flaps and skin grafts survived completely, and the wounds healed by first intention. Ten children underwent 1-4 times of flap de-fatting, finger separation, and trimming. All children were followed up 6-48 months (mean, 26.6 months). No obvious swelling of the flaps occurred, and the texture was soft. At last follow-up, among the 6 children with upper limb defects, 2 had upper limb function grade Ⅳ and 4 had upper limb function grade Ⅴ according to the Carroll upper limb function assessment method. The 4 children with lower limb defects had no limitation of joint movement. The neck flexion and rotation in the 1 child with neck defect significantly improved when compared with that before operation. The 1 child with residual ulcer at the amputation stump could wear a prosthesis and move without limitation, and no new ulcer occurred. Linear scars were left at the donor sites, and no abdominal wall hernia was formed. CONCLUSION The free paraumbilical perforator flap has abundant blood supply and can be harvested in large size. It can be used to repair skin and soft tissue defects in children and has the advantages of short operation time, minimal injury, high safety, and minimal impact on the growth and development of children.

Complex ventral hernia refers to a large hernia that is complicated by a series of concurrent conditions. Change in intra-abdominal pressure is one of the main pathways through which various factors exert an impact on perioperative risk and postoperative recurrence. Taking abdominal pressure reconstruction as the core, the treatment strategy for complex abdominal hernia can be formulated from three aspects: improving patients' tolerance, expanding abdominal cavity volume, and reducing the volume of abdominal contents. Improving patients' tolerance includes abdominal wall compliance training and progressive preoperative pneumoperitoneum. To expand the volume of the abdominal cavity, implanting hernia repair materials, component separation technique, autologous tissue transplantation, component expend technique, and chemical component separation can be used. Initiative content reduction surgery and temporary abdominal closure may be performed to reduce the volume of abdominal contents. For different cases of complex ventral hernia, personalized treatment measures can be safely and feasibly adopted depending on the condition of the patients and the intra-abdominal pressure situation.

With the development of modern surgery, the field of hernia and abdominal wall surgery is undergoing a transformative change, and new techniques, new concepts, and recent progress are being updated, which have motivated the high-quality development of the discipline. In the past two decades, the development of hernia and abdominal wall surgery in China has been recognized by international peers. Many young surgeons have gradually become the main force in the treatment of hernia and leaders in surgical technique. The innovation and development of discipline will never terminate; young surgeons as the main force should seriously think about how to improve their professional qualities. Young surgeons are interested in the innovation of surgical techniques and need to push for a traditional operation on the one hand and an innovative operation on the other. Updates to concepts and acquisition of new materials are more important, which can provide a solid foundation for technological innovation. Young surgeons should start with the basics and classics. Understanding the history and development of new techniques, new concepts and recent progress, and grasping indications of clinical application, is the important part of growing up for young surgeons, which can make surgical treatment more standardized, benefit patients, and promote the progress of Chinese specialized medical education.
