In recent years, the number of patients with vaginal relaxation has increased year by year, and the minimally invasive vaginal contraction has been carried out more and more widely in clinical practice, but the treatment normalization and safety have not been thoroughly studied. We summarized six cases of characteristics and treatment measures for patients with various complications after minimally invasive vaginal contraction surgery from September 2021 to December 2023 at Department of Plastic and Aesthetic Surgery, Peking Union Medical College Hospital. The patients' age ranged from 26 to 44 years. Two cases accepted vaginal contraction with embedded vaginal thread, and four accepted vaginal contraction with acellular allogenic dermis. One patient showed vaginal hyper-tightness, one patient showed subcutaneous suture nodules, two patients showed explosion of acellular allogenic dermis, and three patients showed vaginal infection symptoms such as yellow leucorrhea and peculiar smell. All patients had sexual pain and discomfort. One patient underwent vaginal orifice dilation, one patient underwent suture extraction and secondary vaginal contraction, one patient underwent acellular allogenic dermis extraction and immediate vaginal contraction, two patients underwent acellular allogenic dermis extraction and secondary vaginal contraction, and one patient underwent secondary vaginal contraction. The symptoms of all six patients were relieved after treatment. Despite the short operation time and fast postoperative recovery of minimally invasive vaginal contraction, there are still complications after surgery, causing physical and mental damage to patients. Plastic surgeons, therefore, should be cautious in the treatment process to avoid collateral damage, so that patients get the best treatment effect.

BACKGROUND:The production and release of a large amount of inflammatory factors caused by immune system inflammatory response mainly contributes to secondary spinal cord injury. OBJECTIVE:To investigate the effects of umbilical cord Wharton’s jely mesenchymal stem cel transplantation on repair of injured neurological function and expression of inflammatory factors monocyte chemoattractant protein 1 and interleukin 10 in rats with acute spinal cord injury. METHODS: Eighty-one healthy adult male Sprague-Dawley rats were randomly and equaly divided into sham operation, model and cel transplantation groups, with 27 rats per group. Rats in the latter two groups were subjected to hemisection of the spinal cord to establish acute spinal cord injury models. Rat models in the cel transplantation group received umbilical cord Wharton’s jely mesenchymal stem cel injection (1×106)via the tail vein. Rat neurological function was evaluated using the BBB score at different time points after spinal cord injury. The expression of monocyte chemoattractant protein 1 and interleukin 10 in injured spinal cord tissue was detected using ELISA assay at different time points after spinal cord injury. Migration and neuronal differentiation of umbilical cord Wharton’s jely mesenchymal stem cels in the injured spinal cord tissue were determined using immunohistochemical staining method. RESULTS AND CONCLUSION:Compared with the sham operation and model groups, rat neurological function was significantly recovered in the cel transplantation group (P < 0.05). Compared to the model group, monocyte chemoattractant protein 1 level in the serum and monocyte chemoattractant protein 1 mRNA and protein expression in the injured spinal cord tissue were significantly lower (P < 0.05), but interleukin 10 mRNA and protein expression in the injured spinal cord tissue was significantly higher (P < 0.05), in the cel transplantation group. In the cel transplantation group, umbilical cord Wharton’s jely mesenchymal stem cels could migrate to the injured region and express glial fibrilary acidic protein. These findings suggest that umbilical cord Wharton’s jely mesenchymal stem cels promote rat neurological function recovery by regulating the inflammatory response in the injured spinal cord tissue, which is likely to be one of mechanisms by which transplantation of umbilical cord Wharton’s jely mesenchymal stem cels treats spinal cord injury.

Objective:To investigate the efficacy and safety of a simple three-step excision for combined reduction plastic surgery of labia minora clitoral hood complex.Methods:We selected the clinical data of patients with labia minora and clitoral prepuce hypertrophy treated in the Department of Plastic and Aesthetic Surgery, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences, from May 2017 to November 2021. All the patients underwent composite labia minora and clitoral hood reduction using a simple three-step excision. In the first step, a longitudinal shuttle incision was designed to remove the redundant lateral prepuce of the clitoris; In the second step, the hypertrophic part of labia minora was removed by wedge resection; The third step was to trim the triangular flap formed by the excess skin at the junction of the labia minora and the clitoral hood, and then complete the incision suture. Patients were asked to return for examinations on days 1, 7, and 10 postoperatively. After that, the patients were followed up in the outpatient department or online, and the satisfaction questionnaires were conducted. The contents included appearance improvement, preoperative symptom improvement, postoperative discomfort symptoms, sexual life quality, partner’s evaluation of surgical effect, and patient’s evaluation of surgical impact.Results:A total of 295 patients were enrolled, with an average age of 29 years, ranged from 9 to 52 years old. Patients were divided into 4 categories according to the surgeries they received, including 21 patients (7.1%) with unilateral labia + unilateral prepuce hypertrophy, 12 patients (4.1%) with unilateral labia + bilateral prepuce hypertrophy, 50 patients (16.9%) with bilateral labia + unilateral prepuce and 212 patients (71.9%) with bilateral labia + bilateral prepuce hypertrophy. The incidence of complications was 3.4%(10/295), hematoma occurred in 8 cases, scar hyperplasia with obvious pain in 1 case, and blood supply disorder in 1 case. After the complementary treatments, all patients recovered well from surgeries. 219 questionnaires were obtained three months after surgeries, and 76 cases were lost to follow-up. The overall satisfaction rate of patients was 94.5%(207/219).Conclusions:The preoperative design of three-step resection is simple, which can safely and effectively carry out composite labia minora and clitoral hood reduction, with less complications, concealed incision, slight scar, and high satisfaction.

Objective:To improve and optimize the modified surgical strategies for patents with Simon Ⅰ and Simon Ⅱ type of gynecomastia, based on their magnetic resonance imaging (MRI) features.Methods:Clinical data of 190 patients aged 12 to 56 years (mean age 26.7±8.6) with gynecomastia who underwent modified surgeries in the Department of Plastic Surgery of Peking Union Medical College Hospital from January 2017 to January 2023 were retrospectively analyzed. The study measured breast MRI images of 44 male patients to calculate the area ratio of the glands on the transverse plane via nipple. This provided insight into the physiological structure and the tissue distribution of gynecomastia for improving the modified surgical strategies. All 190 patients were treated with enhanced liposuction and " Pull-Through and Bottom-Up" techniques. The duration of operation, amount of liposuction and amount of glandular resection, postoperative complications were recorded, and postoperative satisfaction was investigated by questionnaire surveys.Results:MRI images of the 87-side male breast showed that the average area ratio of the glands on the transverse plane via nipple was (10.9±12.5) %. The most prevalent subtype of gynecomastia was branch pattern, accounting for 46.0%. The median surgical duration of 190 patients was 95 (65-210) minutes, the median liposuction volume was 300 (50-1 400) ml, and the median glandular removal was 19.9 (1.5-157.0) g. Eighty-eight patients (46.3%) went through followed up for more than 6 months post-posterative with an overall satisfaction score of 4.68±0.53. Postoperative complications occurred in 19 sides (5.1%), and the reoperation rate was 1.3%.Conclusions:The MRI imaging of gynecomastia shows that the component of patients′ breasts are mainly fat, with a small amount of glandular tissue and the dominant subtype is branch pattern. Enhanced liposuction combined with " Pull-Through and Bottom-Up" stab incision technique can be an effective treatment for Simon grades Ⅰ and Ⅱ gynecomastia. The method results in high patient satisfaction with fewer postoperative complications.
