Objective:To summarize the technical experience of using a contralateral free gracilis myocutaneous flap combined with an adductor magnus perforator flap for salvaging failure of breast reconstruction after transplantation with the free adductor magnus perforator flap.Methods:A retrospective analysis was conducted on patients with breast cancer who received contralateral posteromedial thigh flap (gracilis myocutaneous flap combined with adductor magnus perforator flap) transplantation for immediate unilateral breast reconstruction developed vascular crisis and caused flap necrosis at the Department of Oncology Plastic Surgery, Hunan Cancer Hospital, between December 2016 to December 2022. All patients with early-stage breast cancer received modified radical mastectomy. All patients were selected to undergo the immediate breast reconstruction surgery with unilateral free adductor magnus perforator flap transplantation. The proximal end of internal mammary vessels were used as the recipient vessels in all cases. After the emergency exploration confirmed the necrosis of the flap, a contralateral free gracilis myocutaneous flap combined with adductor magnus perforator flap were immediately harvested for salvage breast reconstruction. The vascular pedicle of the gracilis muscular branch and the adductor magnus perforator branch were anastomosed with the proximal and distal ends of the internal mammary vessels, respectively. Postoperative patient monitoring was conducted intensively, with follow-up assessments focusing on breast contour and donor site recovery.Results:A total of 5 patients were included, aged 26 to 42 years, with an average of (31.5±1.8) years. All salvaged breast reconstruction surgeries were successful, the salvaged flap measured 15.0 cm×6.0 cm×4.0 cm-17.0 cm×7.5 cm×5.5 cm. All the transplanted flaps survived after the operation, with satisfactory breast contour, good flap elasticity, and no contracture or deformation. The donor sites of both thigh flaps healed well, leaving only linear scars and no significant functional impairment to the lower limbs. Follow-up ranged from 9 to 24 months, with an average of 15.7 months. The breast shape was satisfactory, and there was no recurrence of breast cancer.Conclusion:The donor site morbidity of the posteromedial thigh flap is relatively small. When unilateral flap transplantation fails, immediate transfer of the contralateral flap can be chosen for salvage reconstruction. This approach ensures symmetrical donor site outcomes and is generally well-accepted by patients.

The free inferior epigastric artery perforator flap is currently a highly regarded autologous breast reconstruction technique. However, in clinical practice, the anatomical characteristics of the lower abdominal vasculature and surrounding tissue structures do not always permit ideal perforator flap harvesting. In many cases, it becomes necessary to preserve a larger rectus abdominis muscle cuff to ensure reliable blood supply to the flap through the perforating vessels. Compared with various forms of rectus abdominis myocutaneous flaps that all require incision of the anterior sheath and intramuscular vascular pedicle dissection, the superficial inferior epigastric artery (SIEA) perforator flap significantly reduces donor-site morbidity. Nevertheless, the anatomical variability of the superficial inferior epigastric vessels increases surgical uncertainty. Based on clinical observations, this study establishes a comprehensive clinical strategy algorithm. Primarily focusing on different configurations of free rectus abdominis flaps, it incorporates additional preparation of free SIEA perforator flaps when anatomical conditions permit. The objectives are to ensure reliable perfusion of the lower abdominal flap while minimizing donor-site damage and reducing surgical complexity.

Pan-immune inflammation value (PIV) is a comprehensive immune inflammatory biomarker based on complete blood cell counts, which has been proven to predict treatment response and survival outcomes for different types of tumors. However, the predictive value of the PIV varies in different strategies for tumor treatment. This paper aims to systematically review the latest progress of PIV in predicting survival outcomes and tumor prognosis for immunotherapy, radiotherapy, targeted therapy, endocrine therapy, surgical treatment and neoadjuvant therapy, and analyze its existing challenges and issues, as well as look forward to its future development direction and application prospects.

Objective To investigate the correlation between pre-treatment pan-immune inflammation value (PIV) and clinicopathological features in esophageal squamous cell carcinoma (ESCC) patients with postoperative adjuvant radiotherapy and evaluate its value in prognosis assessment combined with T stage. Methods A retrospective analysis was conducted on data of 85 ESCC patients with postoperative adjuvant radiotherapy in the Department of Radiation Oncology of the Affiliated Hospital of Yangzhou University from January 2019 to January 2023. The receiver operating characteristic (ROC) curve was drew to obtain the optimal cut-off value of PIV and other immune-inflammatory biomarkers. The area under the curve (AUC) and clinical applicability of PIV and other immune-inflammatory biomarkers were compared based on the ROC curve and decision curve analysis (DCA). According to the optimal cut-off value, patients were divided into high PIV group and low PIV group, and the correlation between PIV level and clinicopathological features of ESCC was evaluated. Kaplan-Meier method was used for survival analysis, the Cox proportional hazards model was used for multivariate analysis, and a risk stratification model combining PIV and T stage was established by recursive partitioning analysis (RPA). Results The optimal cut-off value of pre-treatment PIV was determined as 187.22 based on the ROC curve. The AUC of PIV was 0.679, which was greater than 0.640, 0.583, 0.656 and 0.644 of the other four immune-inflammatory biomarkers such as the systemic immune-inflammation index (SII), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), and neutrophil-to-lymphocyte ratio (NLR). The 85 patients were divided into low PIV group (< 187.22, n=48) and high PIV group (≥187.22, n=37). The level of PIV was significantly correlated with tumor diameter (P < 0.05). The 3-year overall survival (OS) (75.6% versus 30.6%, P < 0.001) and 3-year disease-free survival (DFS) (56.1% versus 21.0%, P < 0.001) were significantly higher in the low PIV group than the high PIV group. Tumor diameter, T stage and PIV were independent factors affecting OS in ESCC patients (P < 0.05), and T stage and PIV were independent factors affecting DFS in ESCC patients (P < 0.05). A new staging system with three risk groups was established by the RPA stratification model based on T stage and PIV, which further improved the predictive value of prognosis compared with T stage or PIV alone. Conclusion Pre-treatment PIV is helpful in predicting the prognosis of ESCC patients with postoperative adjuvant radiotherapy, and the combination of PIV and T stage can improve the predictive value.

Objective:To investigate the risk factors for refracture after percutaneous kyphoplasty (PKP) in patients with osteoporotic vertebral compression fracture (OVCF).Methods:A retrospective cohort study was conducted on the clinical data of 149 OVCF patients who were admitted to the First Affiliated Hospital of Soochow University from June 2019 to June 2022, including 21 males and 128 females, aged 56-97 years [(73.2±8.7)years]. Initial surgical segments included T 7 in 1 patient, T 8 in 10, T 9 in 6, T 10 in 6, T 11 in 19, T 12 in 28, L 1 in 38, L 2 in 18, L 3 in 11, L 4 in 7 and L 5 in 5. Patients were divided into refracture group ( n=32) and non-refracture group ( n=117) according to whether they had postoperative refracture after PKP. Refractured surgical segments included T 8 in 2 patients, T 9 in 2, T 11 in 4, T 12 in 5, L 1 in 7, L 2 in 4, L 3 in 6, and L 5 in 2. The age, gender, underlying diseases (hypertension, diabetes), body mass index (BMI), preoperative bone mineral density (BMD), smoking history, drinking history, follow-up time, preoperative visual analogue scale (VAS), and preoperative Oswestry dysfunction index (ODI) of the two groups were recorded. Preoperative paravertebral muscle-related parameters of the two groups were calculated including cross-sectional area of bilateral psoas, bilateral erector spinae, bilateral multifidus, and vertebral bodies, paravertebral muscle mass, and vertebral bone quality (VBQ) score. Univariate analysis was performed to evaluate the correlation between the fore-mentioned indicators and postoperative refracture after PKP in OVCF patients. Multivariate logistic regression analysis was employed to identify the independent risk factors for postoperative refracture after PKP in OVCF patients. Results:Univariate analysis revealed that there was certain correlation of BMI, preoperative BMD, cross-sectional area of bilateral psoas, bilateral erector spinae, bilateral multifidus, paravertebral muscle mass and VBQ score with postoperative refracture after PKP in OVCF patients ( P<0.01), while no correlation was found between age, gender, hypertension, diabetes, smoking history, drinking history, follow-up time, preoperative VAS, preoperative ODI, or cross-sectional area of vertebral bodies and postoperative refracture after PKP in OVCF patients ( P>0.05). Multivariate logistic regression analysis showed that preoperative BMD ≤-3.4 SD ( OR=0.27, 95% CI 0.09, 0.80, P<0.05), paravertebral muscle mass ≤281.2% ( OR=0.98, 95% CI 0.97, 0.99, P<0.01) and VBQ score ≥4.8 points ( OR=4.41, 95% CI 1.18, 16.44, P<0.05) were significantly correlated with postoperative refracture after PKP in OVCF patients. Conclusion:Preoperative BMD ≤-3.4 SD, paravertebral muscle mass ≤281.2%, and VBQ score ≥4.8 points are the independent risk factors for refracture after PKP in OVCF patients.

Objective:To explore the clinical value and therapeutic effects of endoscopic nipple-sparing mastectomy combined with immediate breast reconstruction using an oblique pedicled rectus abdominis myocutaneous flap(ORAMF).Methods:The data of patients admitted to Hunan Cancer Hospital from May to September 2023 who underwent breast cancer resection followed by immediate breast reconstruction with ORAMF were analyzed retrospectively. Surgical methods: firstly, axillary anterior sentinel lymph node biopsy and subcutaneous glandular excision for breast cancer were performed through a lateral chest incision using an endoscopic technique. Subsequently, a unilateral ORAMF was prepared by removing the epidermis and creating subcutaneous tunnels on the surface of the rectus abdominis myocutaneous flap under direct visualization. The subcutaneous tunnel of the flap was then extended to the deep surface of the breast with the assistance of an endoscope, allowing for the transfer of the ORAMF to reconstruct the breast. Post surgery, the flap survival was monitored, and after discharge, patients received enhanced anti-scar treatment and functional rehabilitation exercises. Follow-up assessments included the evaluation of the reconstructed breast shape, incision scarring in both the donor and recipient areas, abdominal wall function, tumor recurrence and metastasis.Results:A total of 8 female patients with unilateral breast cancer were included in this study, aged between 27 and 52 years, with a mean age of 41.7 years old. The body mass index of the patients ranged from 19.1 to 22.5 kg/m 2. All patients had early-stage breast cancer. During the operation the average mass of the resected breast was 245 g(ranging from 220 to 285 g). The length of the lateral thoracotomy incision varied from 6.9 to 9.5 cm, with a mean length of 7.7 cm. In 3 cases, the ipsilateral ORAMF was used for breast reconstruction, while in 5 cases, the contralateral ORAMF was utilized. The dimensions of the flap were as follows: length (20.4±0.7) cm, width (10.8±1.5) cm, thickness (5.4±0.9) cm, with the volume of the flap cutting ranging from 19.7 cm×9.2 cm×4.4 cm to 21.2 cm×11.8 cm×5.9 cm. All of the flaps exhibited good blood supply and survived successfully without the need for additional anastomotic vessels. The patients were followed up for a period of 8 to 10 months post-operation, with an average follow-up of 8.7 months. The reconstructed breasts maintained a good shape and texture, showing no contracture or deformation of the flap, and were generally symmetrical with the healthy breast. The incisions in both the flap donor area and the recipient area had healed well, leaving only linear scars, and the function of the abdominal wall was not significantly compromised. No recurrence or metastasis was observed during the follow-up period. Conclusion:The endoscopic technique helps to preserve the integrity of the breast skin tissue to the greatest extent possible, reducing scarring and assisting in the creation of subcutaneous tunnels to facilitate the transposition of the ORAMF for breast reconstruction. For carefully selected patients with moderately small breasts and ample subcutaneous tissue in the lower abdomen, the preparation of a unilateral ORAMF for breast reconstruction can yield superior results. This approach minimizes additional damage to the donor area, enhancing the safety of the surgery while significantly reducing the complexity of the operation.

AIM: To evaluate the safety and efficacy of ultrasonic cycloplasty(UCP)combined with anti-vascular endothelial growth factor(VEGF)+ panretinal photocoagulation(PRP)in the treatment of advanced neovascular glaucoma(NVG).METHODS: Retrospective study. A total of 45 patients(45 eyes)with advanced NVG who received surgery in our hospital from August 2020 to September 2022 were collected and divided into UCP+ anti-VEGF +PRP group(16 patients, 16 eyes), transscleral cyclophotocoagulation(TCP)+anti-VEGF+PRP group(20 patients, 20 eyes), UCP alone group(9 patients, 9 eyes). The intraocular pressure, pain scores, postoperative medication, effective rate, total success rate and the incidence of complications of the patients in the three groups were compared before surgery and at 1 d, 1 wk, 1 and 3 mo after surgery.RESULTS: There was no significant difference in preoperative intraocular pressure, pain scores and preoperative medication of patients in the three groups(all P>0.05). While there were statistical significance in the intraocular pressure and pain scores at 1 d, 1 wk, 1 and 3 mo after surgery(all P<0.01). The intraocular pressure of the UCP alone group(31.78±10.23 mmHg)was found to be higher than that of both the UCP+ anti-VEGF +PRP group(19.44±8.23 mmHg)and the TCP+ anti-VEGF +PRP group(20.80±10.27 mmHg)at 1 mo postoperatively(all P<0.017). The pain score of the TCP+ anti-VEGF +PRP group at 1 d and 1 wk postoperatively was higher than both the UCP+ anti-VEGF +PRP group and the UCP alone group(all P<0.017). The effective rates of UCP+ anti-VEGF +PRP group, TCP+ anti-VEGF +PRP group and UCP alone group were 81%(13/16), 75%(15/20)and 67%(6/9), respectively,(P=0.675), and the success rates were 69%(11/16), 50%(10/20), and 0(0/9), respectively(P=0.003). There was no significant difference in complications of patients in the three groups(P>0.05).CONCLUSION: UCP combined with anti-VEGF +PRP and TCP combined with anti-VEGF +PRP showed comparable efficacy in reducing intraocular pressure in advanced NVG. UCP combined with anti-VEGF+PRP was more effective in relieving pain and with no serious complications in advanced NVG. UCP alone can effectively control intraocular pressure and alleviate the pain of patients in the early postoperative period, but long-term control still requires anti-VEGF+PRP.

Objective:To observe alterations in center retinal thickness (CRT) in patients diagnosed with central retinal artery occlusion (CRAO) before and after undergoing superselective arterial thrombolysis (IAT) treatment.Methods:A retrospective clinical study. From August 2022 to September 2023, 12 patients (12 eyes) diagnosed with CRAO and treated with IAT at the ophthalmology department of Shenzhen Second People's Hospital. Among these patients, there were 8 males (8 eyes) and 4 females (4 eyes), all experiencing unilateral onset. The mean age was (47.00±15.06) years. The mean duration from onset to thrombolysis was (30.00±30.42) h. All eyes underwent best corrected visual acuity (BCVA) and optical coherence tomography (OCT) assessments; additionally, 6 eyes underwent Fluorescein fundus angiography (FFA). BCVA assessments were conducted using a standard logarithmic chart and transformed into logarithm of the minimum angle of resolution (logMAR) values for statistical analysis. The OCT measured CRT at various locations around the macular fovea (M), including upper (S1, S3), lower (I1, I3), nasal (N1, N3), and temporal (T1, T3) areas at 1 mm and 3 mm distances from the fovea. CRT was defined as the vertical distance between the inner retinal boundary membrane and the inner interface of the retinal pigment epithelial layer. Pre- and post-IAT examinations were performed using the same equipment and methodologies within a 24-hour interval. Changes in CRT at different macular points were compared and observed, while arterial imaging time changes were assessed in 6 eyes that underwent FFA. Paired t-tests were utilized to analyze logMAR BCVA, CRT at different locations, and arterial imaging time pre- and post-treatment. Results:Prior to IAT treatment, the logMAR BCVA for the affected eye was 3.48±1.42, while the arterial imaging time for the 6 eyes undergoing FFA examination was (27.50±5.47) s. After 24 hours, the logMAR BCVA had improved to 2.35±1.59 for the affected eye, with 9 eyes showing varying degrees of BCVA improvement. The arterial imaging time was (24.17±7.28) s post-treatment. The differences in logMAR BCVA and arterial imaging time before and after treatment were found to be statistically significant ( t=2.489, 3.262; P<0.05). Additionally, the comparison of CRT at S3 ( t=2.871), I1 ( t=2.325), and T3 ( t=3.446) before and after treatment yielded statistically significant differences ( P<0.05). Conversely, the comparison of CRT at S1 ( t=1.879), I3 ( t=1.915), N1 ( t=2.001), N3 ( t=1.987), T1 ( t=2.180), and M ( t=-0.490) showed no statistically significant differences ( P>0.05). Conclusions:IAT treatment for CRAO has been shown to be effective in achieving therapeutic effects by reducing CRT in the macular area. However, the short-term improvement in retinal edema in the macular area is limited.
