Objective To evaluate the surgical method and the results of endoscopic decompression and anterior transposition of the ulnar nerve for treatment of cubital tunnel syndrome. Methods Between May 2008 and August 2009, 13 cases of cubital tunnel syndrome were treated with endoscopic decompression and anterior transposition of the ulnar nerve. There were 4 males and 9 females with an average age of 47.5 years (range, 32-60 years). The injury was caused by fractures of the humeral medial condyle in 1 case, by long working in elbow flexion position with no obvious injury in 10 cases, and subluxafion of ulnar nerve in 2 cases. The locations were the left side in 6 cases and the right side in 7 cases. The disease duration was 4-30 months. The time from onset to operation was 3-20 months (mean, 8.5 months). Ten patients compl icated by intrinsic muscle atrophy. Results The operation was successfully performed in 13 cases, and the operation time was 45-60 minutes. All the wounds gained primary heal ing. All patients were followed up 12-18 months (mean, 14 months). The numbness of ring finger, l ittle finger, and the ulnar side of hand were decreased obviously on the first day after operation. The examination of electromyogram showed that the ulnar nerve conduction increased at 2 weeks, the ampl itude was improved, and recruitment of the intrinsic muscles of hand enhanced. In 10 cases compl icated by intrinsic muscle atrophy, myodynamia was recovered to the normal in 7 cases and was mostly recovered in 3 cases at 3 months after operation. The symptom of cubital tunnel syndrome disappeared and gained a normal function at 12 months after operation. According to the assessment of Chinese Medical Association and Lascar et al. grading criteria, the cl inical results were excellent in 10 cases and good in 3; the excellent and good rate was 100%. Patients recovered to work 12-16 days (mean, 14 days) after operation. No recurrence occurred during followup. Conclusion The surgical method of endoscope and microscope assisted three small incisions for treatment cubital tunnel syndrome has less invasion with small incision and complete decompression. Patients can recover to work early. It is a convenient and efficient procedure for treating cubital tunnel syndrome.
From 1984 to 1994, 236 different types of traumatic defects of foot were repaired by microsurgical tissue grafting. They included simple cutaneous flap in 187 and composite flap in 49. Among the 236 different tissue flaps, vascularized flap was used in 97 and pedicled flap in 139. The 4 fore-foot and 6 heel defects were repaired by composite skeleted cutaneous grafts with scapula and vascularized febula respectively. After the follow-up from 1 to 10 years, all the grafted tissues were survived and healed well. The functions were satisfactory, and 186 patients had resumed their original works. The key to good function following repair was to maintaion the integrity of foot structures and the sensation of the sole and heel.
Reconstruction and repair of atresia or defect of the upper portion of esophagus is difficult. From November 1980 to December 1997, forth-five cases, consisting 35 males and 10 females, were treated with microsurgical technique. The 45 patients fell into the following groups as esophageal atresia of various causes in 21 cases, anastomotic fistula or stenosis following reconstruction of esophagus in 7 cases and late carcinoma of esophagus in 17 cases. The types of reconstruction consisted of transfer of free jejunum with its lower portion carrying a vascular pedicle in 24 cases, free transfer of jejunal graft in 15 cases, free vascularized jejunal graft in 2 cases and free vascularized tubular skin graft in 4 cases. After a follow-up of 6-19 months besides eight cases died from late esophageal carcinoma, thirty-seven cases were survived and could take food by mouth. All of the benign cases could return to work. In patients having late esophageal carcinoma, the operative procedure could improve the life quality and facilitate chemotherapy and radiotherapy.
Seventeen cases involving 18 fingers of acute rupture of flexor tendon within the Zone Ⅱ were repaired by microsurgical technique for reconstructing the digital sheath with biological membrane since 1989. The excellent/good rate based on Eaton grading was 89%. The main procedure of the operation. the early postoperative rehabilitation and active excercises were described.
ObjectiveTo summarize the advancement of precise diagnosis and treatment for spastic cerebral palsy in recent years.MethodsThe literature and own experiences were reviewed, and the surgical method, precise diagnosis, and personalized treatment of spastic cerebral palsy based on the classification of spastic cerebral palsy were summarized and analyzed.ResultsThe common classification of spastic cerebral palsy are gross motor function classification system (GMFCS) and manual ability classification system (MACS). The surgical methods of spastic cerebral palsy can be divided into soft tissue surgery, nerve surgery, and bone and joint surgery. The precise diagnosis of spastic cerebral palsy includes qualitative diagnosis, localization diagnosis, and quantitative diagnosis. Based on precise diagnosis and classification, one or more corresponding surgical methods are selected for treatment.ConclusionThe manifestations of spastic cerebral palsy are so diverse that it is necessary to select rational surgeries based on precise diagnosis to achieve individualized treatment.
ObjectiveTo study the effectiveness of Keystone flap in the repair of soft tissue defect of lower extremity.MethodsThe clinical data of 27 cases with soft tissue defects of lower extremity treated by Keystone flap between January 2018 and June 2020 were retrospectively analyzed. There were 18 males and 9 females, with an average age of 43.9 years (range, 8-63 years). The cause of soft tissue defects included skin tumor in 3 cases, ulcer in 2 cases, soft-tissue infection in 8 cases, trauma in 7 cases, and donor site defect after free or pedicled flap transplantation in 7 cases. Defect size ranged from 2.0 cm×1.5 cm to 15.0 cm×9.5 cm. The types of Keystone flaps included type Ⅰ in 2 cases, type Ⅱa in 16 cases, type Ⅱb in 1 case, type Ⅲ in 6 cases, and Moncrieff modified type in 2 cases. The area of flap ranged from 3.0 cm×1.5 cm to 20.0 cm×10.0 cm. The donor site was directly sutured (26 cases) or repaired with skin grafting (1 case).ResultsThe operation time was 45-100 minutes, with an average of 67.5 minutes; the hospitalization stay was 3-12 days, with an average of 8.5 days. Postoperative incision dehiscence occurred in 1 case, and flap marginal necrosis occurred in 2 cases, all of which were completely healed after dressing change; 1 case of incision was swollen and congested with tension blisters, which resolved spontaneously at 7 days after operation. The other flaps and the skin grafting survived and healed successfully, the wounds of recipient and donor sites healed by first intention. The healing time was 2-3 weeks (mean, 2.2 weeks). No pain occurred in all patients. All 27 cases were followed up 3-26 months (mean, 11.5 months). No obvious scar contracture and bloated skin flap were found. The texture and color of the skin in the recipient area were similar to those of the surrounding tissues and feel existed.ConclusionThe Keystone flap is a feasible and efficient way to repair soft tissue defect of lower extremity. Furthermore, the skin color and texture is similar to the surrounding tissue after healing.
Objective To summarize the current management of anterior cruciate ligament (ACL) injury in children and adolescents, in order to provide reference for the management of ACL injury in children and adolescents. MethodsThe relevant literature at home and abroad in recent years was extensively accessed to summarize the management status of ACL injury in children and adolescent. Results The number of ACL injury in children and adolescents is increasing every year. The diagnosis of ACL mainly depends on symptoms and signs. Rehabilitation, physeal-sparing techniques, partial transphyseal techniques, all-epiphyseal techniques, and transphyseal techniques are used to treat ACL injury in children and adolescents. Conclusion Dynamic monitoring of knee joint in children and adolescents should be strengthened. The best treatment for ACL injury in children and adolescents is selected according to the patients’ actual age, bone age, Tanner stage, and physiological conditions such as menstruation, body growth speed, and other characteristics.
ObjectiveTo introduce a modified sutureless technique and its surgical results in the treatment of total anomalous pulmonary venous connection (TAPVC).MethodsClinical data of 11 patients with TAPVC who underwent the modified sutureless technique treatment from 2014 to 2019 in our center were retrospectively analyzed, including 4 males and 7 females. The median surgical age was 1.4 (0.3, 27.0) months. The median weight was 4.3 (3.5, 8.5) kg.Six (54.5%) patients were of supracardiac subtype, and five (45.5%) patients were of infracardiac subtype. Five (45.5%) patients had preoperative severe pulmonary hypertension, and three (27.3%) patients had preoperative pulmonary vein obstruction. The surgical results were compared with those of 10 patients treated with conventional surgical technique.ResultsThe median follow-up was 12 (range, 1-65) months. During the follow-up, no death or postoperative pulmonary vein obstruction occurred in the modified sutureless technique group. The perioperative data and relief of re-obstruction were superior in the modified sutureless technique group, but the difference was not statistically significant (P>0.05). The postoperative survival of the the modified sutureless technique group was better than that of the traditional surgery group (P=0.049).ConclusionThe modified sutureless technique which includes partial suture and then incising, and eversion of pulmonary vein incision, is a safe and reliable method for the treatment of TAPVC with satisfactory short-term results.
ObjectiveTo explore the technique of hepatic artery reconstruction in complicated hilar cholangiocarcinoma surgery. MethodThe clinicopathologic data of 3 patients with complicated hilar cholangiocarcinoma with arterial invasion underwent hepatic artery reconstruction in the Department of Hepatopancreatobiliary Center of Beijing Tsinghua Changgung Hospital from March to July 2022 were retrospectively analyzed. ResultsAll 3 patients (case 1–3) were the males, aged 53, 68, and 56 years, respectively, and with hypertension or diabetes; the longitudinal diameters of the tumor were 3.5 cm, 3.0 cm, and 3.2 cm, respectively. All patients had the right hepatic artery invasion. Case 2 and 3 had the arterial stratification. The arterial defects after radical resection were 4.5 cm, 3 cm, and 3 cm, respectively. The right or right posterior hepatic artery was reconstructed by the autotransplantation of right gastroomental artery, the left hepatic artery, and the anterior superior pancreaticoduodenal artery, respectively. After operation, the reconstructed hepatic arteries were unobstructed and free of stenosis, and there were no complications such as bleeding, infection, and thrombosis by Doppler ultrasound and CT angiography. The results of postoperative pathological diagnosis were the hilar cholangiocarcinoma with arterial invasion, and all the incisal edges were negative. ConclusionFrom the preliminary results of 3 cases, it is safe, feasible, and effective to select proper autologous artery (matched in length and caliber) for reconstruction the defective invaded hepatic artery which resected together with hilar cholangiocarcinoma, but the technical difficulty is still relatively high.
Lung transplantation has developed in China for nearly half a century. The Wuxi lung transplant team completed our first lung transplantation on September 28, 2002. By the year of 2021, the total number of lung transplantation in China has been increased to 775, while 49 medical centers have been qualified to perform lung transplantation. During the past two decades, we vigorously promoted lung transplantation technique, cooperated and communicated with colleagues in relevant specialties. Thus, more and more patients with end-stage lung diseases could be evaluated and transplanted to save their lives, with the support of medical insurance and funds. The full-process monitoring and staged objective management, have been well established regarding to donor evaluation standards and acquisition procedures, the green channel for organ transportation, postoperative intensive care unit management, prevention of rejection and infection, as well as long-term follow-up of recipients. Based on the classical lung transplantation surgical techniques, technical breakthroughs have been made while the public’s acknowledgement of lung transplantation has been also enhanced. In the future, lung transplantation techniques will be increasingly challenged by new technologies and ethics, bringing diversified opportunities and challenges to the lung transplantation team collaboration.
