Objective To evaluate the clinical results of bioabsorbable interference screw in knee ligament reconstruction. Methods From April 2002 to August 2004, 39 patients with knee ligament injury were treated, including 33 males and6 females with a median age of 25 years (15 to 65 years). The involved ligament included 29 anterior cruciate ligament of knee(ACL), 6 posterior cruciate ligament of knee(PCL)，4 combined ACL and PCL, 3 medial collateral or lateral collateral ligaments of knee point and 1 posterolateral complex injury of knee. All of patients underwent anatomic ligament reconstructions under arthroscopy or open surgery by autografts and fixation with bioabsorbable interference screw. Results All 34 patients were followed up 6 to 28 months (mean 13.7months). The patients were evaluated by Lysholm knee functional scales, the knee scores were 43.6±13.4 before operation and 85.4±16.3 after operation, showing significant difference (Plt;0.05). There was no limitation of rangeof motion and loosening of the screw. However, one case suffered from infection, and 3 cases suffered from effusion and synovitis after surgery and recovered after management. Conclusion Bioabsorbable interference screw fixation is a reliable method in knee ligament reconstruction and is effective to restore knee joint stability.
ObjectiveTo analyze the value of indocyanine green (ICG) fluorescence imaging in the evaluation of blood flown of ipple-areola complex (NAC) and implant selection during single-port endoscopic breast reconstruction. Methods From November 2018 to March 2020, 19 patients who underwent single-port inflatable endoscopic nipple-sparing mastectomy combined with breast reconstruction in Beijing Friendship Hospital were retrospectively collected. ICG fluorescence imaging technology was used to evaluate the blood supply pattern and the risk of ischemic necrosis of NAC, so as to guide the selection of implant. At the same time, 14 patients who underwent single-port inflatable endoscopic nipple-sparing mastectomy combined with breast reconstruction in Beijing Friendship Hospital from February 2017 to October 2018 were selected as the historical control group (control group). NAC ischemic necrosis, breast satisfaction and implant removal were compared between the two groups. Results In the ICG group, there were3 cases of V1 pattern and 2 cases of NAC ischemic necrosis (1 case of grade 1, 1 case of grade 2). There was no NAC ischemic necrosis in 16 patients with V2 mode and V3 mode. No implant loss occurred in any of the patients. In the control group, 5 cases had NAC ischemic necrosis (all were severe ischemic necrosis), and 2 cases had implant loss. The rate of severe NAC ischemic necrosis in the ICG group was lower than that in the control group (P<0.01), but there was no significant difference in implant loss rate between the two groups (P=0.17). The breast satisfaction score of the ICG group was higher than that of the control group (P<0.01), but there were no significant difference in satisfaction scores of chestwell-being, psychological well-being and sexual well-being between the two groups (P>0.05). Conclusions ICG imaging can be used to evaluate the blood supply pattern during the operation of prosthetic body mass reconstruction, guide the choice of implant in immediate breast reconstruction, so as to further improve postoperative breast satisfaction.
Abstract: ObjectiveTo explore the surgical characteristics of primary tracheal tumors treatment and its prognosis. Methods [WTBZ]We retrospectively investigated the clinical records of 38 patients with primary tracheal tumors in both Xiangya Hospital of Central South University and Hunan Provincial Tumor Hospital from Febuary 1982 to August 2009. There were 24 males and 14 females aged from 7 to 65 years. There were 2 benign lesions, 13 adenoid cystic carcinomas, 11 squamous cell carcinomas, 5 mucoepidermoid carcinomas, 4 adenocarcinomas and 3 other cell types. One patient with adenocarcinoma underwent exploratory thoracotomy only; 33 patients underwent tracheal resection and airway reconstruction, and according to the tumor growth characteristics, the surgeon applied circumferential tracheal resection with endtoend anostomosis or wedge resection; One patient had papilloma resected under fiber bronchoscopy; and three patients with locally advanced lesions underwent radiotherapy without surgery. The overall survival rate was calculated by the KaplanMeier method. The logrank method was used for comparing survival rates among different groups, characterized by cell types or surgical procedures. Results [WTBZ]The patient with exploratory thoracotomy died 3 days after surgery from respiratory failure. The perioperative mortality was 2.94% (1/34), and all the remaining 33 patients recovered and were discharged from hospital. Minor complications happened to 12 patients (35.29%), including 6 patients with pulmonary infection, 4 with atelectasis, and 2 with hoarseness. The followup time ranged from 6 months to 15 years. The followup rate was 97.29% (36/37). The threeunresected patients died within 6 months after hospital discharge. The 1, 5, and 10year survival rate for resected patients was88% （95%CI 0.77 to 0.99), 47%(95%CI 0.29 to 0.66), and 41% (95%CI 0.21 to 0.61), respectively. The survival rate of adenoid cystic carcinoma or mucoepidermoid carcinoma was significantly higher than that of squamous cell carcinoma or other tissue types (χ2=17.581, P=0.001). There was no statistical difference (χ2=0.021, P=0.886) in 5 year survival rate between wedge resection group at 63%(95%CI 0.34 to 0.91) and the segmental resection group at 77%(95%CI 0.44 to 0.99). Conclusions [WTBZ]Surgical treatment is safe and beneficial for primary tracheal tumors, and the pathological type is a significant prognostic factor after complete resection.

ObjectiveTo investigate the indications and clinical effects of tricuspid cone reconstruction and tricuspid valve replacement in the treatment of downward displacement of tricuspid valve (Ebstein anomaly).MethodsThe clinical data of 22 patients with Ebstein anomaly who underwent surgical treatment in our hospital from January 2013 to March 2020 were collected. There were 7 males and 15 females, aged 4-56 (33.68±17.78) years. The patients were divided into two groups according to different surgical methods: a tricuspid cone reconstruction group (tricuspid valvuloplasty group, n=12) and a tricuspid valve replacement group (n=10). The curative effect of the two operative methods were compared.ResultsTwenty-two patients underwent surgical treatment under general anesthesia and cardiopulmonary bypass. One patient died of severe low cardiac output syndrome during operation. Downward displacement of tricuspid septum was found in 22 patients, and downward displacement of tricuspid septum and posterior septum in 21 patients, downward displacement of tricuspid in 8 patients. Twelve patients were treated with tricuspid valvuloplasty, 10 patients with tricuspid valve replacement, and patients with other intracardiac structural malformations were treated at the same time. Postoperative cardiac doppler ultrasound indicated no tricuspid regurgitation in 9 patients, mild regurgitation in 8 patients, and moderate regurgitation in 4 patients. No perivalvular leakage occurred in all patients undergoing valve replacement. Four patients developed degree Ⅲ atrioventricular block after operation, among whom 3 patients recovered to sinus rhythm and 1 patient implanted the permanent pacemaker. Twenty-one patients were cured and discharged after successful operation, and were followed up for 3 to 78 months, with a follow-up rate of 100.0%. During the follow-up period, there was no severe tricuspid regurgitation in tricuspid valvuloplasty group, but mild or moderate regurgitation was found. After tricuspid valve replacement, only 1 patient had mild regurgitation, and the rest patients had no valve regurgitation.ConclusionTricuspid valvuloplasty and tricuspid valve replacement are effective in the treatment of Ebstein anomaly, and the tricuspid regurgitation is less severe after tricuspid valve replacement operation. The operation method should be selected according to the different anatomical characteristics and condition of tricuspid valve. The combined intracardiac malformation or arrhythmia can be dealt with simultaneously.
ObjectiveTo assess the mid-term effectiveness of anterior cruciate ligament (ACL) revision and to analyze the relevant factors that may affect the surgical outcomes.MethodsThe clinical data of 24 patients who underwent ACL revision surgery between April 2009 and July 2018 and were followed up for more than 2 years were retrospectively analyzed. There were 20 males and 4 females with a median age of 30 years [interquartile distance (IQR) was (25, 36) years]. The median body mass index was 24.45 kg/m2 and IQR was (22.93, 25.93) kg/m2. The median time between ACL revision and reconstruction was 41 months and IQR was (15, 85) months. The direct cause of the failure of reconstruction surgery included 14 cases of trauma, 8 cases of no obvious cause, and 2 cases of infection. During the revision operation, 14 patients had a poor bone tunnel position, all of which were drilled with new tunnels, the remaining 10 patients were freshly modified on the basis of the original bone tunnel. Seventeen patients used autogenous tendon revision, 7 patients used LARS ligament; 16 patients had cartilage injury. The Lysholm score, the International Knee Documentation Committee (IKDC) score, and the Tegner sports rating score were used for functional evaluation before operation, at 1 year after operation, and at last follow-up. The Likert satisfaction score was recorded at last follow-up.ResultsPatients were followed up with a median time of 47 months and IQR was (32, 61) months. The Lysholm score, IKDC score, and Tegner sports rating score were significantly improved at 1 year after operation and at last follow-up when compared with preoperative scores (P<0.05). There was no significant difference between at last follow-up and at 1 year after operation (P>0.05). At last follow-up, the median Likert satisfaction score was 4.0 and IQR was (3.0, 4.5). According to the presence or absence of cartilage damage and the type of graft, the above scores at last follow-up were compared between the groups, and the differences were not significant (P>0.05). At last follow-up, 2 patients had graft fractures due to trauma again, and autogenous iliac bones were taken to fill the bone tunnel, and the second stage was revised; the rest of the patients recovered satisfactorily.ConclusionWith preoperative identification of the cause of ACL reconstruction failure, the stability and function of knee joint can be significantly improved by selecting appropriate bone tunnels and grafts during the revision and by active rehabilitation exercises.
In tracheal resection and reconstruction, a technically demanding, complex, and high-risk procedure, management of the anastomotic site significantly impacts postoperative outcomes and long-term quality of life. However, comprehensive studies detailing perioperative anastomotic management strategies in tracheal reconstruction remain scarce. This review summarizes perioperative management strategies for tracheal reconstruction, covering preoperative assessment, surgical techniques, and other key aspects. It also highlights future research directions and challenges, aiming to provide clinicians with a systematic guide to perioperative management in tracheal reconstruction.
Objective To explore the value of the application of latissimus dorsi myocutaneous flap in the breast reconstruction. Methods The clinical data of the 36 patients with breast tumor who had undergone breast reconstruction with latissimus dorsi myocutaneous flap from January 2012 to December 2016 were collected retrospectively. The postoperative complications and cosmetic results were analyzed. Results Thirty-six patients with breast tumor who underwent breast reconstruction with latissmus dorsi myocutaneous flap, including 32 patients with immediate breast reconstruction and 4 patients with delayed breast reconstruction respectively. The operative time of the patients who undertwent immediate breast reconstruction was 235–490 min (mean of 325 min), the intraoperative blood loss was 200–260 mL (mean of 220 mL), and the hospitalization time was 18–33 d (mean of 23.6 d). The total operative time of patients who underwent delayed breast reconstruction was 325–550 min (mean of 355 min), the total intraoperative blood loss was 200–250 mL (mean of 220 mL), and the total hospitalization time was 27–45 d (mean of 32.5 d). The cosmetic results was excellent in 22 patients, good in 8 patients, fair in 6 patients, respectively, and fine rate was 83.3% (30/36). There was no flap loss, but donor site seroma occurred in 21 patients, partial necrosis of the surgical margin of back skin occurred in 1 patient, partial necrosis of the nipple and areola skin occurred in 2 patients. All the patients were followed-up for 3–60 months, and the mean follow-up time was 37 months. During the follow-up period, no patient occurred metastasis or recurrence. After undergoing radiotherapy, reconstructive breast volume of 2 patients significantly contracted. None of the patients had significant limb function. Conclusion The breast reconstruction with the latissimus dorsi myocutaneous flap is a simple, easy, and effective surgical procedure.
ObjectiveTo evaluate the effectiveness of intra-articular radioulnar ligament reconstruction in the treatment of chronic instability of the distal radioulnar joint. MethodsBetween January 2006 and June 2012, the intra-articular radioulnar ligament reconstruction was used to treat chronic instability of the distal radioulnar joint in 12 patients. Of 12 cases, 8 were males and 4 were females with an average age of 37.3 years (range, 22-54 years). The causes of injury were tumble in 9 patients, traffic accident in 2 patients, and sprain in 1 patient. The average time from initial injury to operation was 6.2 months (range, 2-13 months). The pain and function of the wrists were assessed with Patient-Rated Wrist Evaluation (PRWE) (27.5±4.7). Broadening of the distal radioulnar joint space was seen on the anteroposterior radiograph in all the patients. Lateral view showed dorsal instability in 10 patients and palmar instability in 2 patients. There was no radial fracture, ulnar fractures or degeneration of the distal radioulnar joint. ResultsAll patients achieved primary healing of incision. No complication of deep infection or nerve injury occurred. They were followed up from 12 to 30 months (mean, 20.6 months). Pain and the clicking sound of the wrists disappeared; grip strength increased; the range of motion values of the wrist and forearm were restored. PRWE score was 5.8±2.1 at last follow-up, showing significant difference when compared with preoperative score (t=14.215, P=0.000). Imaging examination showed good appositions of the distal radioulnar joint, with no dislocation or subluxation. ConclusionIntra-articular radioulnar ligament reconstruction can rebuild the anatomic stability of the distal radioulnar joint, which does not damage the adjacent structures of the joints and can obtain satisfactory function of the reconstructed joint. It is a good choice for chronic instability of the distal radioulnar joint without articular degeneration.
