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.

The successful replantation of a severed limb by CHEN Zhongwei in 1963 marked the beginning of microsurgery in China. The complete survival of a completely severed finger replantation and the successful free transplantation of the second toe to reconstruct the thumb in 1966, as well as the successful transplantation of a free inguinal skin flap in 1973, were all landmark achievements. The Guangzhou Experience Exchange Conference on Limb Replantation in 1972 and the American Replantation Mission to China in 1973 promoted academic exchanges and technology dissemination both domestically and internationally in China’s microsurgery field. China’s limb (finger) replantation techniques and principles were recognized and promoted worldwide, and Chinese microsurgery developed in step with the world and created many world firsts. Since then, Chinese microsurgery has long been among the advanced academic ranks internationally.
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.
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.
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.
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.
Objective To investigate the management strategies of external fixation combined with microsurgical techniques for repairing complex foot and ankle wounds in children. MethodsThe clinical data of 9 children with complex foot and ankle wounds who met the selection criteria between June 2017 and December 2021 was retrospectively analyzed. There were 6 boys and 3 girls, aged 3-13 years, with an average of 7.4 years. The causes of injury included crush injury in 5 cases and traffic accident injury in 4 cases. The wound size ranged from 6 cm×5 cm to 25 cm×18 cm. The time from injury to surgery ranged from 3 to 8 hours, with an average of 5 hours. All cases underwent staged surgical treatment. Among the 3 cases requiring deformity correction, 2 cases initially underwent free anterolateral thigh flap transplantation for wound coverage and limb salvage, followed by circular external fixation combined with osteotomy to address postoperative limb deformity, while 1 case received osteotomy for tibial fracture realignment prior to local pedicled flap reconstruction. All the 6 cases with non-deformity correction underwent initial external fixation followed by secondary flap reconstruction for wound management. The American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score was used to evaluate the foot and ankle function of children. Results All children successfully achieved limb salvage postoperatively. Among the 6 non-deformity correction cases, all flaps survived with satisfactory wound healing and no infection was observed; fractures healed within 2.5-4.5 months, after which external fixators were removed for functional rehabilitation with favorable recovery. One case treated with circular external fixation combined with osteotomy achieved bone union at 4 months postoperatively, followed by fixator removal. One case undergoing osteotomy for tibial fracture realignment showed bone healing at 2.5 months post-correction, with subsequent fixator removal. One patient receiving bone lengthening developed infection at 1 week postoperatively, which was managed with multiple debridements, ultimately achieving bone union at 16 months postoperatively and followed by fixator removal. At last follow-up, all patients demonstrated satisfactory ankle-hindfoot functional recovery, with AOFAS ankle-hindfoot scores ranging from 80 to 90 (mean, 84.2). Conclusion The combination of external fixation and microsurgical techniques demonstrates significant advantages in reconstructing complex foot and ankle wounds in children. The synergistic interaction provides both mechanical stability and biological repair, enabling early functional rehabilitation while reducing infection risks.
