Constricted posterior fourchette deformities: Definition, classification and surgical treatment.

BACKGROUND: Labiaplasty is one of the top cosmetic procedures patients are seeking in the past two years. However, treatment of disease in posterior fourchette caused by various etiological factors was less investigated and neglected. METHODS: Three types of posterior fourchette deformity were proposed: (1) Redundant posterior fourchette, (2) Relaxed posterior fourchette, and (3) Constricted posterior fourchette. Local flap transfer technique was applied. Y-V-plasty and 5-Z-Flap-plasty were used to treat web type and tight type of the constricted posterior fourchette, respectively. Follow-ups were arranged on the Internet or at the outpatient clinic. Visual analogue scale (VAS) was utilized to evaluate sexual discomfort in the satisfaction questionnaires during follow-up. RESULTS: A total of 48 patients with constricted posterior fourchette deformity from May 2022 to May 2023 were reviewed in the study. Y-V-plasty could decrease VAS in patients with web-type deformity by 4.13 ± 1.46 (p＜0.001). 5-Z-Flap-plasty could decrease VAS in patients with tight-type deformity by 3.76 ± 1.53 (p＜0.05). Satisfaction rates of the web type and tight type were 93.1% (27/29) and 86.7% (13/15) respectively. Complications include two cases of hematoma, one case of persistent pain and two cases of dehiscence. CONCLUSION: Constricted posterior fourchette seriously affects the quality of life. Y-V-plasty and 5-Z-Flap-plasty can be utilized to treat the two subtypes of constricted posterior fourchette, which can effectively reduce the pain score of patients with high satisfaction and few long-term complications.

Comprehensive aesthetic corrections of gynecomastia using the reproducible safe and minimally invasive surgical strategy.

BACKGROUND: Minimally invasive access and fast recovery are trends of gynecomastia surgery. We placed great importance on liposuction and modified original pull-through technique. The purpose of this study was to present a refined surgical strategy for gynecomastia in grade I and II. METHODS: The refined strategy embraced enhanced liposuction to remove the intraglandular fat sufficiently, followed by open resection of gland using the pull-through and bottom-up technique with adjuvant liposuction in the end. Surgical data were recorded and satisfactory questionnaires with 5-point scales were administered during follow-up. RESULTS: Between January 2017 and May 2022, 165 patients underwent enhanced liposuction combined with the pull-through and bottom-up technique for gland excision. Age ranged from 12 to 56 years. The median length of surgery was 100 min. A median of 300 ml of fat was aspirated and a median of 20.8 g of gland was excised. Seventy-seven patients (46.7%) responded the questionnaires at least 6 months postoperatively, and the average overall satisfaction was 4.68 ± 0.52 points. Thirteen sides of breasts developed complications with a rate of 4.0%. CONCLUSION: Enhanced liposuction combined with pull-through and bottom-up technique proved effective to treat grade I and II gynecomastia with minimal scarring and high satisfaction. The refined strategy was simple and safe, and would obtain optimal outcomes even for inexperienced surgeons.

Risk assessment and management of preoperative venous thromboembolism following femoral neck fracture.

BACKGROUND: Limited studies are available to investigate the prevalence of preoperative venous thromboembolism (VTE) in elderly patients with femoral neck fractures. Our primary aim was to determine the incidences of VTE and its risk or protective factors in such patient population. The secondary objective was to evaluate the need of therapeutic anticoagulation for isolated calf muscular venous thrombosis (ICMVT) prior to femoral neck fracture surgery. METHODS: This is a retrospective case-control study, including 301 femoral neck fracture patients who were admitted to our institution between January 2014 and March 2017. Bilateral Doppler ultrasonography was performed in each of the patients as a preoperative VTE screening. The event rate of VTE was calculated, and significant risk or protective factors were determined by using a multivariate logistic regression model. Patients with ICMVT were divided into anticoagulation and no anticoagulation groups to assess the efficacy and safety of preoperative therapeutic anticoagulation. Intraoperative blood loss, drainage volume, blood transfusion, perioperative hemoglobin change, and rate of thrombosis extension were compared between the two groups. RESULTS: The overall preoperative incidence of VTE in patients with femoral neck fracture was 18.9% (57/301), in which deep vein thrombosis (DVT) was 18.9% and pulmonary embolism (PE) was 1%. Among the DVT cases, 77.2% (44/57) were ICMVTs. Multiple fractures (odds ratio [OR] = 9.418; 95% confidence interval [CI] = 2.537 to 34.96), coexisting movement disorder (OR = 3.862; 95% CI = 1.658 to 8.993), bed rest for more than 7 days (OR = 2.082; 95% CI = 1.011 to 4.284) as well as elevated levels of D-dimer (OR = 1.019; 95% CI = 1.002 to 1.037) and fibrinogen (OR = 1.345; 95% CI = 1.008 to 1.796) led to an increase in the risk of VTE, while the recent use of antiplatelet drug (OR = 0.424; 95% CI = 0.181 to 0.995) and prophylactic anticoagulation (OR = 0.503; 95% CI = 0.263 to 0.959) decreased the risk of VTE. For the 39 patients with ICMVT undergoing femoral neck fracture surgery, there were no significant differences in the rate of thrombosis extension between anticoagulation and no anticoagulation groups, but significantly decreased postoperative hemoglobin was observed in the anticoagulation group. CONCLUSION: Our findings showed a high prevalence of preoperative VTE in elderly patients with femoral neck fracture, with risk factors identified. We found that the most detected VTE were ICMVTs. Our study suggested that a direct surgery without preoperative use of therapeutic anticoagulation for ICMVT would not reduce the risk of thrombus extension, and the therapeutic use of anticoagulation may worsen postoperative anemia.

Low molecular weight heparin for the prevention of deep venous thrombosis after total knee arthroplasty: A systematic review and meta-analysis.

BACKGROUND: To systematically evaluate the prophylaxis efficacy of low-molecular-weight heparin (LMWH) in the prevention of deep venous thrombosis (DVT) after total knee arthroplasty (TKA). METHOD: PubMed, Cochrane, Embase, Wanfang, CNKI, and VIP databases were searched by index words to identify the eligible RCTs; relevant literature sources were also searched. The latest research was conducted in March 2017. Relative risks (RR), mean difference (MD), and their corresponding 95% confidence intervals (95% CIs) were used to analyze the main outcomes. RESULT: A total of 22 articles were included in the meta-analysis with a total number of 11,320 patients (5543 in the LMWH group and 5777 in the control group). The results indicated that in the LMWH group, the incidence of DVT (OR: 0.57, 95% CI: 0.41-0.77) and wound complications (SMD: 0.96, 95% CI: 0.75-1.22) was significantly lower than that in the control group. Furthermore, LMWH also increased the occurrence of bleeding event (OR: 1.57, 95% CI: 1.31-1.88) and the total blood transfused (SMD: 0.12, 95% CI: 0.04-0.19). However, no statistical difference was found in blood loss (SMD: -0.26, 95% CI: -0.65-0.14) between the two group. In the subgroup analysis, the incidence of DVT was significantly decreased in the ardeparin sodium group (OR: 0.70, 95%CI: 0.53-0.94) and the dalteparin group (OR:0.40, 95%CI:0.32-0.50). CONCLUSION: Our meta-analysis demonstrated that LMWH is obviously efficacious in the prophylaxis of DVT after TKA. However, it has some negative effects, such as the increase in the number of bleeding events and the total blood transfused.

Laparoscopic-Assisted Resection for Advanced Colorectal Cancer in Solid Organ Transplant Recipients.

AIM: To evaluate the feasibility, short- and long-term outcomes, and safety of laparoscopic resection for advanced colorectal cancer (CRC) in solid organ transplant recipients. METHODS: Between September 2001 and April 2016, five patients who underwent laparoscopic-assisted resection for CRC after solid organ transplantation were included in this study. Their clinical data were retrospectively analyzed with regard to patient demographics, immunosuppressive therapy, tumor characteristics, surgical outcomes, and follow-up data. RESULTS: Four kidney and one heart transplant recipients were included. Laparoscopic-assisted low anterior resection was performed in four patients with rectal or rectosigmoid junction cancer, and sigmoidectomy was done in one with sigmoid colon cancer. One kidney transplant patient received a protective loop transverse colostomy. All resections achieved complete tumor removal with tumor-free margins and total mesorectal excision, with an average number of 14 lymph nodes harvested. Most tumors were in stage III (n = 3), one was in stage II, and one in stage IV. The mean duration of surgery, intraoperative blood loss, and postoperative hospital stay were 144 min, 105 mL, and 8.8 days, respectively. No major complications occurred and graft function stayed well. During a mean follow-up period of 62 months, two patients developed metastasis and died eventually. CONCLUSION: Laparoscopic resection for advanced CRC in organ transplant recipients is technically feasible and therapeutically safe, and seems to have the advantages of few postoperative complications, short recovery time, and acceptable oncological outcomes.
