Safety and clinical outcomes of thoracoscopic segmentectomy in bilateral lung cancer: A single-center retrospective study / 中国胸心血管外科临床杂志

@#Objective     To assess the safety and clinical outcomes of segmentectomy in one- or two-staged video-assisted thoracoscopic surgery (VATS) for bilateral lung cancer. Methods    We retrospectively enrolled 100 patients who underwent VATS segmentectomy for bilateral lung cancer at the Department of Thoracic Surgery of Peking Union Medical College Hospital from December 2013 to May 2022. We divided the patients into two groups: a one-stage group (52 patients), including 17 males and 35 females with a mean age of 55.17±11.09 years, and a two-stage group (48 patients), including 16 males and 32 females with a mean age of 59.88±11.48 years. We analyzed multiple intraoperative variables and postoperative outcomes. Results     All 100 patients successfully completed bilateral VATS, and at least unilateral lung received anatomical segmentectomy. Patients in the one-stage group were younger (P=0.040), had lower rate of comorbidities (P=0.030), were less likely to have a family history of lung cancer (P=0.018), and had a shorter interval between diagnosis and surgery (P=0.000) compared with patients in the two-stage group. Wedge resection on the opposite side was more common in the one-stage group (P=0.000), while lobectomy was more common in the two-stage   group. The time to emerge from anesthesia in the one-stage group was longer than that in the first and second operations of the two-stage group (P=0.000, P=0.002). Duration of surgery and anesthesia were similar between two groups (P>0.05). Total number of lymph node stations for sampling and dissection (P=0.041) and lymph nodes involved (P=0.026) were less in the one-stage group. Intraoperative airway management was similar between two groups (P>0.05). The one-stage group was associated with lower activities of daily living (ADL) scores. Conclusion     Segmentectomy is safe in one- or two-staged VATS for bilateral lung cancer, including contralateral sublobectomy and lobectomy. Duration of surgery and perioperative complications are similar between two groups, but the one-stage group is associated with lower ADL scores. On the basis of comprehensive consideration in psychological factors, physical conditions and personal wishes of patients, one-staged sequential bilateral VATS can be the first choice.

One-stage surgery in patients with both cardiac and non-cardiac diseases / 北京大学学报(医学版)

OBJECTIVE@#To investigate the possibility and feasibility of one-stage cardiac and non-cardiac surgery.@*METHODS@#From July 1999 to August 2018, one hundred and eleven patients suffering from cardiac and non-cardiac diseases were treated by one-stage cardiac and non-cardiac operation in Department of Cardiac Surgery and Thoracic Surgery, General Surgery, Urinary Surgery, and Gynecology, Peking University First Hospital. There were 83 males (74.8%) and 28 females (25.2%), aged 41 to 84 years [mean age: (64.64±8.97) years]. The components of the cardiac disease included coronary heart disease, valvular heart disease, cardiac tumors, chronic constrictive pericarditis and congenital heart disease. The components of the non-cardiac diseases included lung benign and malignant diseases, thymoma and thymic cyst, breast cancer, chest wall giant hemangioma, digestive tract benign and malignant diseases, urinary system carcinoma and gynecological diseases.@*RESULTS@#Two patients died after operations in hospital; thus, the hospital mortality rate was 1.8%. One patient died of multiple organ failure on the 153th days after emergency coronary artery bypass grafting (CABG) combined with radical resection of bladder cancer. The other of pericardium stripping with lung cancer operation died of the multiple organ failure on the tenth day after surgery. The remaining 109 patients recovered and were discharged. There were 13 cases of complications during the days in hospital. The total operative morbidity was 11.7%: postoperative hemorrhage in 2 cases (1.8%), pulmonary infection and hypoxemia in 3 cases (2.7%), hemorrhage of upper digestive tract in 1 case (0.9%), incisional infection in 3 cases (2.7%), subphrenic abscess in 1 case (0.9%), and postoperative acute renal failure and hemofiltration in 3 case (2.7%). Of the 109 patients discharged, 108 patients were followed up. All the patients survived for 6 months, and 21 patients died due to tumor recurrence or metastasis within 1 to 5 years of follow-up, but no cardiogenic death. During the follow-up period, 1 patient developed cardiac dysfunction, 1 patient underwent percutaneous coronary intervention (PCI), 1 patient had cerebral hemorrhage due to excessive postoperative anticoagulation, and 1 patient suffered from incisional hernia.@*CONCLUSION@#One-stage surgeries in patients suffering from both cardiac and non-cardiac benign or malignant diseases are safe and possible with satisfactory short-term and long-term survival.

10 year institutional experience of use of buccal mucosal grafts for complex urethral reconstruction for varied indications with its outcome

Background: The objective of the study was to evaluate long term efficacy and outcome of use of buccal mucosal graft (BMG) for urethral reconstruction in varied urologic conditions in children.Methods: We retrospectively reviewed the medical records of 41 patients from 2009 till 2019 in our institution in which BMG was used for urethral reconstruction. Clinical findings along with surgical techniques used were noted for these patients. Postoperative outcome and complications were evaluated.Results: Mean age was 6.8 years and mean follow up was for 4 years. Out of 41 patients, BMG for substitution urethroplasty was used in 25 cases of hypospadias, 4 cases of urethral stricture, 6 cases of 46 XY disorders of sexual disorders, 4 cases of Y-duplication of urethra, and 2 cases of redo-epispadias repair. 11 patients underwent one stage repairs with a success rate of 63% and 30 patients underwent two stage repair with a success rate of 66%. Analysis and comparison of the outcome in relation to the type of repair, meatal position and number of surgical procedures prior to BMG urethroplasty was statistically insignificant.Conclusions: Buccal mucosa is an ideal graft substitute for urethroplasty. Two stage reconstructions has a slightly higher success rate than one stage reconstruction but the choice of the technique must be based on patients characteristics and on surgeons preference.

One stage three-column osteotomy for the treatment of scoliosis with split spinal cord malformation / 中国骨伤

OBJECTIVE@#To analyze the effectiveness and safety of one stage three column osteotomy in treatment of scoliosis with split spinal cord malformation.@*METHODS@#The clinical data of 41 patients with scoliosis and split spinal cord malformation underwent one-stage three-column osteotomy from January 2015 to December 2017 were retrospectively analyzed. There were 17 males and 24 females with average age of (25.14±4.51) years old and the average weight of (65.14±9.11) kg. According to the classification of longitudinal spina bifida, 15 cases of Pang typeⅠwere group A and 26 cases of Pang typeⅡwere group B. The general situations of two groups were recorded ; preoperative and postoperative Cobb angle were observed and the correction rate of Cobb angle of coronal plane was calculated ; the coronal and sagittal torso offset distances were compared between two groups and the trunk balance was evaluated ; the complication of two groups was recorded.@*RESULTS@#All 41 patients were followed up for more than 12 months. The operation time, intraoperative blood loss, and perioperative blood transfusion volume in group A were (610.14±115.02) min, (4 001.12±1 014.33) ml, (3 951.14±1 021.55) ml, respectively, and group B were (520.12±101.14) min, (2 701.57±1 021.45) ml, (2 565.77±880.47) ml, the difference between the two groups was statistically significant (0.05). There was no significant difference in postoperative coronary Cobb angle and correction rate between two groups (>0.05). Immediately after surgery and 12 months after surgery, there was no significant difference in the trunk displacement distance of coronal view and sagittal view between two groups (>0.05). Six patients in group A had complications, which was higher than that in group B of 1 case (=4.885, < 0.05).@*CONCLUSION@#One-stage three-column osteotomy in treatment of scoliosis with split spinal cord malformation has high correction rate and good balance of the trunk. However, for patients with typeⅠsplit spinal cord malformation, they will face longer operation time, more intraoperative bleeding volume, large amount of perioperative blood transfusion and higher risk of complications, and the safety is not as good as that of typeⅡpatients. Therefore, in the actual treatment of scoliosis, especially for those with typeⅠsplit spinal cord malformation, a more reasonable surgical plan should be developed in combination with the actual situations of the patients, so as to improve the safety of the operation.

Infección periprotésica de rodilla ¿influye la estrategia quirúrgica en el resultado funcional? / Total knee arthroplasty infection, what is the best strategy for better functional outcomes?

Resumen: Introducción: La estrategia quirúrgica al enfrentarnos a las infecciones periprotésicas de rodilla sigue siendo controvertida. Los objetivos del tratamiento son la erradicación de la infección, la mejoría del dolor y de la función articular. El manejo quirúrgico incluye el desbridamiento y retención del implante, el recambio protésico en un tiempo o el recambio en dos tiempos. Esta última estrategia quirúrgica se considera el «gold standard¼, alcanzando unas tasas de curación hasta de 80%-100%, aunque poco se ha publicado acerca de los resultados funcionales. Material y métodos: Estudio retrospectivo de 65 pacientes, con infección periprotésica de rodilla. En 20 pacientes se realizó un recambio en un tiempo y en 45 pacientes fueron recambios en dos tiempos. Evaluación pre- y postoperatoriamente con la escala modificada HSS. Todos los pacientes fueron tratados con antibioterapia intravenosa, evaluamos la respuesta analítica y clínica para confirmar la erradicación o no de la infección. Resultados: La infección se resolvió en 39 de 65 pacientes, 12 en el grupo de recambio en un tiempo y 27 para el grupo de dos tiempos. Sin diferencia significativa entre los grupos en relación con curación ni resultado funcional. Sin embargo, hay una diferencia estadísticamente significativa entre aquellos pacientes que recibieron tratamiento antibiótico vía oral antes del diagnóstico y aquéllos que no lo recibieron. Conclusión: La tasa de curación es similar en los tratados con recambio en un tiempo y recambio en dos tiempos. No pudimos demostrar superioridad en los resultados funcionales entre los dos grupos.

Abstract: Introduction: Surgical strategy in dealing with periprosthetic knee infections remains controversial. The goals of treatment are to eradicate infection, improve pain and joint function. Surgical management includes implant debridement and retention, prosthetic replacement in one-time, or two-stage replacement. This latest surgical strategy is considered the «gold standard¼, reaching healing rates up to 80%-100%, although little has been published about functional results. Material and methods: Retrospective study of 65 patients with periprosthetic knee infection. In 20 patients a replacement was made in a time and in 45 patients were in two stages. Pre- and post-operative evaluation with the modified HSS scale. All patients were treated with intravenous antibiotherapy, we evaluated the analytical and clinical response to confirm the eradication or not of the infection. Results: The infection was resolved in 39 out of 65 patients, 12 in the replacement group in a time and 27 for the two-stages group. No significant difference between the groups in relation to healing or functional result. However, there is a statistically significant difference between those patients who received oral antibiotic treatment prior to diagnosis and those who did not. Conclusions: The healing rate is similarly treated with replacement in a time and replacement in two times. We were unable to demonstrate superiority in the functional results between the two groups.

Present situation and prospect of diagnosis and treatment of periprosthetic joint infections / 中华外科杂志

Periprosthetic joint infection (PJI) as an insurmountable challenge has always represented a serious concern for orthopedic surgeons. Accurate diagnosis and reasonable treatment of PJI are the keys to deal with this challenge.The diagnosis of PJI is mainly based on clinical manifestations, joint fluid biochemistry, pathogen culture and biomarkers at present. New pathogen culture methods and specific biomarkers in recent years are hot topics in PJI research. In terms of treatment, two-stage revision is still considered to be the 'gold standard’ protocol. However, more and more centers around the world have begun to accept and try one-stage revision as a treatment for PJI.

One-stage repair of ankle fracture combined with grade Ⅲ injury to lateral ligament / 中华创伤骨科杂志

Objective To investigate the surgical outcomes of one-stage repair of the ankle fracture combined with grade Ⅲ injury to the lateral ligament.Methods From April 2015 to December 2017,23 patients with ankle fracture and lateral ligament injury were treated at Department of Traumatic Reconstruction Surgery/Foot and Ankle Surgery,Zhongnan Hospital.There were 15 males and 8 females,aged from 18 to 65 years (average,37.8 years).After intraoperative treatment of their fractures,22 ruptures of the ligamentous insertion were repaired with suture anchor and one rupture of the middle ligament with Internal Brace.Routine postoperative X-rays,physical examination and Sefton grading system were used to evaluate the stability of the ankle joint and the subtalar joint.The Karlsson-Peterson and American Orthopedic Foot and Ankle Society (AOFAS) scores were used to evaluate the function and pain of the ankle.Results The follow-up for this cohort ranged from 12 to 24 months (average,13.9 months).The bone union time ranged from 6 to 24 weeks,averaging 10.1 weeks.There was no chronic instability of lateral ankle or subtalar joint in all the cases.Two cases developed osteochondral lesion of the medial talus which was treated with micro-fracture surgery one year after injury;one case suffered subtalar arthritis which was treated by subtalar arthrodesis 14 months after injury.Their Karlsson-Peterson scores averaged 84.6 points and AOFAS ankle-hindfoot scores 93.7 points with 19 excellent and 4 good cases.The Sefton grading system gave 9 cases of grade Ⅰ and 14 ones of grade Ⅱ.Conclusion One-stage repair of the ankle fracture combined with grade Ⅲ injury to the lateral ligament can lead to the stability of the ankle joint and the subtalar joint and improved function of the ankle.

Consensuses and controversies on one-stage resection and anastomosis surgery in patients with acute obstructive colorectal cancer / 中国实用外科杂志

Acute intestinal obstruction is one of the common causes of emergency surgery in patients with colorectal cancer,which is usually with poor prognosis. Surgery is the most important way to relieve obstruction and save the lives. One-stage resection and anastomosis can completely remove the tumor, restore the continuity of the intestine, avoid complications of staged surgery and reduce disease burden,and is supposed to be the most ideal surgery. However,due to certain intraoperative technical difficulties and the risk of anastomotic leakage,it is still controversial whether the one-stage resection and anastomosis surgery can be preferred during emergency exploration.

@#Objective    To compare the clinical effect of three operations for one-stage radical correction of small left ventricle in children with tetralogy of Fallot (TOF). Methods    We retrospectively analyzed the clinical data of 120 patients with left ventricular dysplasia and TOF undergoing one-stage radical surgery in the First Hospital of Hebei Medical University from December 2004 to May 2017. According to the different types of operation used, they were divided into 3 groups, including a routine group (30 patients, 16 males and 14 females, aged 11.58±2.05 months ranging from 3-24 months), a large patch group (40 patients, 22 males, 18 females, aged 11.22±2.24 months ranging from 3-25 months) who were treated with a large patch, and an enlarged ventricular septal defect group (50 patients, 26 males, 24 females, aged 10.17±2.15 months ranging from 3-22 months) using new left ventricular enlargement technique to enlarge ventricular septal defect. The clinical effect of the three operations were compared. Results    The incidence of postoperative low cardiac output syndrome (6.0% vs. 40.0% vs. 50.0%, P<0.05), renal failure (4.0% vs. 37.5% vs. 46.7%, P<0.05), infection rate (10.0% vs. 50.0% vs. 66.7%, P<0.05), mortality (2.0% vs. 12.5% vs. 20.0%, P<0.05), ventilator-assisted time (8.34±5.24 h vs. 36.14±10.91 h vs. 38.58±10.12 h, P<0.05), ICU stay (4.13±1.01 d vs. 7.64±2.11 d vs. 8.03±3.03 d, P<0.05), hospital stay (10.48±4.26 d vs. 21.02±3.23 d vs. 22.52±2.93 d, P<0.05) and hospitalization costs (51 300±9 400 yuan vs. 103 200±39 300 yuan vs. 115 500±35 200 yuan, P<0.05) were less in the enlarged ventricular septal defect group compared with the other two groups. Conclusion    The clinical effect of enlarged ventricular septal defect is better than that of the routine and large patch methods, and long-term efficacy should be further followed up.

Concurrent Surgery of Craniectomy and Splenectomy as Initial Treatment in Severe Traumatic Head Injury: A Case Report / 대한신경손상학회지

It is not a common case for neurosurgery department and the other departments to perform joint operation at the same time. Patients with severe head injury are a condition in which vital signs are unstable due to severe brain swelling and increased intracranial pressure, and emergency surgery is required. A 44-year-old man visited the trauma center with a motorcycle accident. The Glasgow Coma Scale score at the time of emergency department was 3 points, and the pupil was fixed at 6 mm on both sides. His medical history was unknown. His vital signs including blood pressure (BP), heart rate, respiratory rate and oxygen saturation were stable. Associated injuries included multiple fractures of whole body. Brain computed tomography revealed subarachnoid hemorrhage, intraventricular hemorrhage and severe cerebral edema. During the preparation of the craniectomy, abdominal ultrasonography performed because of decreased BP resulted in a large amount of hemoperitoneum. The bi-coronal craniectomy and splenectomy were performed simultaneously for about 4 hours. After fifty days of treatment, he was discharged with Glasgow Outcome Scale-extended 4 points and is undergoing rehabilitation. In severe polytrauma patients, active concurrent surgery is a good method to save their lives.

One Stage Posterior Minimal Laminectomy and Video-Assisted Thoracoscopic Surgery (VATS) for Removal of Thoracic Dumbbell Tumor

OBJECTIVE: This study was conducted to assess the surgical results of one-stage posterior minimal laminectomy and video-assisted thoracoscopic surgery (VATS) for the treatment of thoracic dumbbell tumor and to describe its precise technique. In addition, we investigated the technique's usefulness and limitations. METHODS: Seven cases of thoracic dumbbell tumor (two men and five women, mean age, 43 years) were analyzed retrospectively. Pathological findings included schwannoma in four patients, neurofibroma in two patients, and hemangioma in one patient. The location of tumors varied from T2/3 to T12/L1. Dumbbell tumors were resected by one-stage operation using posterior laminectomy followed by VATS without instrumentation. Clinical data were reviewed. RESULTS: The mean follow-up period was 25 months (range, 3–58 months), and the operative time ranged from 255 to 385 min (mean, 331 min), with estimated blood loss ranging from 110 to 930 mL (mean, 348 mL). The tumor was completely resected without instrumentation and postoperative instability in all cases. Postoperative complications included atelectasis and facial anhydrosis in one case each. CONCLUSION: One-stage posterior minimal laminectomy and VATS may be a safe and less invasive technique for removal of thoracic dumbbell tumor without instability. This method has the advantage of early ambulation and rapid recovery because it reduces blood loss and postoperative pain.
