ABSTRACT
Due to the inherent disease characteristics and surgical difficulties, the develop-ment of minimally invasive surgery in biliary tract cancer has encountered more difficulties and controversies. As one of the representative fields of modern precise surgery and an important part of multidisciplinary therapy, the value and application of minimally invasive surgery in the treatment of biliary tract cancer need to be further elaborated and standardized. Minimally invasive surgical techniques should be explored and studied under reasonable norms and supervision. More higher level evidence-based evidences should be obtained under the premise of ensuring the ethical prin-ciple of maximum benefit to patients, and ultimately promote the overall progress in the field.

ABSTRACT
The hepatic caudate lobe is located in the deep back area of the liver. Due to the unique anatomical position of hepatic caudate lobe, surgical treatment for tumor of hepatic caudate lobe is particularly difficult. Non-surgical treatment, such as ablation, transarterial embolization, etc, is also challenging for tumor of hepatic caudate lobe, and the therapeutic effect is inferior to that of surgery. Therefore, surgical resection is the only treatment for tumor of hepatic caudate lobe. The authors discuss the research history of hepatic caudate lobe, the problems of laparoscopic technique in hepatic caudate lobe resection, etc, in order to provide a theoretical basis for improving the concept of accuracy of laparoscopic caudate lobectomy.

(5) Analysis of influencing factors of postoperative complications. ① Analysis of influencing factors of intestinal obstruction in patients with radical resection of rectal cancer. Age as 20?39 years and 40?59 years, surgical approach as laparoscopic radical colorectal cancer surgery and NOSES were independent protective factors of intestinal obstruction in patients with radical resection of rectal cancer ( odds ratio=0.46, 0.59, 0.43, 0.13, 95% confidence interval as 0.21?1.00, 0.36?0.96, 0.33?0.56, 0.06?0.27, P<0.05). ② Analysis of influencing factors of incision complications in patients with radical resection of rectal cancer. Body mass index as 24.0?26.9 kg/m 2, surgical approach as laparoscopic radical colorectal cancer surgery and NOSES were independent protective factors of incision complications in patients with radical resection of rectal cancer ( odds ratio=0.24, 0.63, 0.46, 95% confidence interval as 0.11?0.51, 0.44?0.89, 0.24?0.87, P<0.05). ③ Analysis of influencing factors of pulmonary infection in patients with radical resection of rectal cancer. The surgical approach as laparoscopic radical colorectal cancer surgery was an independent risk factor of pulmonary infection in patients with radical resection of rectal cancer ( odds ratio=2.15, 95% confidence interval as 1.46?3.18, P<0.05), and tumor TNM staging as 0?Ⅰ stage was an independent protective factor ( odds ratio=0.10, 95% confidence interval as 0.01?0.88, P<0.05). ④ Analysis of influencing factors of other complica-tions in patients with radical resection of rectal cancer. Age as 20?39 years, 40?59 years, 60?79 years, body mass index as <18.5 kg/m 2, 18.5?23.9 kg/m 2, 24.0?26.9 kg/m 2, 27.0?29.9 kg/m 2, surgical approach as laparoscopic radical colorectal cancer surgery were independent protective factors of other complications in patients with radical resection of rectal cancer ( odds ratio=0.10, 0.29, 0.37, 0.08, 0.22, 0.35, 0.32, 0.29, 95% confidence interval as 0.01?0.81, 0.13?0.64, 0.17?0.78, 0.02?0.40, 0.09?0.52, 0.15?0.83, 0.12?0.89, 0.14?0.59, P<0.05). Conclusions:Compared to laparoscopic radical colorectal cancer surgery and NOSES, open radical colorectal cancer surgery has wide indication and short operation time, but less perioperative treatment effect. Laparoscopic radical colorectal cancer surgery and NOSES can achieve better surgical result and less postoperative complication when patients meeting surgical indications.
ABSTRACT
Gastric cancer is one of the most common malignant tumors in the world, and its incidence and mortality are among the top of malignant tumors in China. Since Kitano et al com-plete the first laparoscopic radical gastrectomy for gastric cancer in the world in 1992, the laparos-copic technology has developed rapidly. After more than 30 years of exploration and practice, the clinical diagnosis and treatment of gastric cancer in China has also made considerable progress. A large number of clinical studies at home and abroad have confirmed that laparoscopic radical gas-trectomy is no less effective than traditional open surgery in the short and long term. Laparoscopic radical gastrectomy has the characteristics of less trauma, faster recovery of gastrointestinal func-tion, less postoperative pain, and shorter average hospital stay. It has gradually replaced open surgery as the mainstream surgical method for gastric cancer. As the concept of surgical treatment for gastric cancer continues to update, emerging minimally invasive technologies continue to emerge, including robotic surgery systems and indocyanine green tracing technology, which are increasingly used in gastric cancer surgery, making gastric cancer surgery more minimally invasive and accurate, the quality of perigastric lymph node dissection and the domestic gastric cancer surgery technology further improving. Based on the relevant research at home and abroad, the authors review and summarize the latest progress in recent years with the topic of minimally invasive surgery for gastric cancer, aiming to systematically describe the current situation and future prospects of gastric cancer surgery. It is believed that in the future, the clinical diagnosis and treatment of gastric cancer in China will be more standardized, minimally invasive and accurate, more high-quality multicenter clinical research will be carry out and the diagnosis and treatment of gastric cancer will be further improved in China.
ABSTRACT
The application of minimally invasive surgery has experienced rapid develop-ment for more than 30 years. The continuous development of minimally invasive technology and instru-ments in the fields of energy platform and imaging equipment has promoted the progress of laparos-copic surgery to be more accurate and secure, and the development of laparoscopic surgery itself has also continuously fed back the innovation of technology and instruments. In recent years, the innovative development of minimally invasive technology and instruments has been more closely combined with the current scientific and technological frontier, leading to the innovative achievements in the fields of robotic surgery, screenless surgery, artificial intelligence, electronic instrument, virtualization and so on. In the new era, surgeons should always keep an eye on the forefront of science and technology, the combination of surgery and technology, application of advanced technology to solve the key problems of current surgery, so as to inject new vitality into the next development of minimally invasive surgery.
ABSTRACT
OBJECTIVE@#To investigate clinical effect of percutaneous reduction combined with internal fixation of calcaneal nail in treating Sanders typeⅡto Ⅲ calcaneal fractures.@*METHODS@#From July 2017 to August 2019, clinical data of 98 patients with Sanders typeⅡto Ⅲ calcaneal fractures treated were retrospectively analyzed, and divided into observation group and control group according to different surgical methods. In observation group, there were 35 males and 21 females, aged from 23 to 58 years old with an average of (34.50±7.81) years old;29 patients with Sanders typeⅡand 27 patients with Sanders type Ⅲ;30 patients on the left side and 26 patients on the right side;the time from fracture to operation ranged from 1 to 4 days with an average of (3.45±0.54) days;and treated with percutaneous reduction combined with internal fixation of calcaneal nail system. In control group, there were 25 males and 17 females, aged from 25 to 60 years old with an average of (35.27±7.64) years old;23 patients with Sanders type Ⅱ and 19 patients with Sanders type Ⅲ;24 patients on the left side and 18 patients on the right side;the time from fracture to operation ranged from 2 to 5 days with an average of (3.42±0.62) days;and treated with open reduction and internal fixation. Operation time, blood loss, hospital stay, fracture healing time, and postoperative visual analogue scale (VAS) at 1 day, preoperative and postoperative American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Böhler angle, Gissane angle and calcaneus width, and postoperative complications were compared between two groups.@*RESULTS@#All patients were followed up from 13 to 18 months with an average of (15.6±2.2) months. There were significant differences in operation time, blood loss, hospital stay, fracture healing time and postoperative VAS at 1 day between two groups (P<0.05). There was statistical difference in postoperative AOFAS score at 12 months between two groups (P<0.05), and AOFAS score at 12 months after operation was higher than that before operation (P<0.05). According to AOFAS score, 21 patients got excellent result, 30 good and 5 moderate in observation group, and 10 excellent, 22 good, 7 moderate and 3 poor in control group, which had statistical difference between two groups (P<0.05). Postoperative Böhler angle, Gissane angle and calcaneus width at 6 months were better than that before operation between two groups(P<0.05). One patient in observation and 20 patients in control group occurred skin numbness after operation, and 14 patients occurred skin necrosis in control group, there were obvious difference between two groups(P<0.01).@*CONCLUSION@#Compared with open reduction and internal fixation, percutaneous reduction combined with internal fixation system in treating Sanders typeⅡto Ⅲ calcaneal fractures is feasible for fracture repair without waiting for foot deswelling, which could accurately restore normal shape and position of the fractured heel bone, completely eliminate fracture malunion, and reduce postoperative complications. Therefore, it could shorten operation time, hospital stay, fracture healing time, reduce amount of blood loss, promote postoperative recovery, and less complications, high safety, which could be used as a choice of orthopedic surgery for foot and ankle trauma.

Resumen ANTECEDENTES: La vasculatura miometrial aumentada es una afección poco común, con alto riesgo de hemorragia masiva. Su fisiopatología se relaciona con una remodelación inadecuada del endometrio y miometrio, posterior a un evento obstétrico. El tratamiento convencional, en caso de sangrado masivo, es la histerectomía. En la actualidad, los tratamientos con enfoque conservador que permiten el embarazo espontáneo, ofrecen una opción segura para estas pacientes. CASO CLÍNICO: Paciente de 20 años, primigesta, con deseo gestacional a futuro, llevada a la sala de urgencias debido a una hemorragia uterina profusa, con datos clínicos de bajo gasto, antecedente de aborto completo de 10 semanas de gestación un mes antes. En el ultrasonido Doppler se observó una imagen anecoica irregular en el fondo uterino que interrumpía la interfase endometrio-miometrial asociada con flujo sistólico alto. Para el control vascular se indicó cirugía conservadora de útero, con ligadura temporal laparoscópica de las arterias uterinas; además aspiración uterina. Estos procedimientos trascurrieron sin complicaciones. El reporte histopatológico del material aspirado fue de tejido trofoblástico asociado con ectasia vascular. CONCLUSIÓN: La ligadura temporal laparoscópica de las arterias uterinas es un procedimiento eficaz, en casos seleccionados, de control vascular durante la extracción del tejido trofoblástico remanente, en casos de vasculatura miometrial aumentada, relacionada con el embarazo, con recuperación completa de la irrigación uterina y preservación del útero.
Abstract BACKGROUND: Enlarged myometrial vasculature is a rare condition with a high risk of massive haemorrhage. Its pathophysiology is related to inadequate remodelling of the endometrium and myometrium following an obstetric event. The conventional treatment for massive haemorrhage is hysterectomy. Currently, conservative management approaches that allow spontaneous pregnancy offer a safe option for these patients. CLINICAL CASE: 20-year-old primigravida with future pregnancy aspirations, presented to the emergency department with heavy uterine bleeding, clinical data of low output, history of complete abortion at 10 weeks' gestation one month earlier. Doppler ultrasound showed an irregular anechoic image in the uterine fundus interrupting the endometrial-myometrial interface associated with high systolic flow. For vascular control, uterine-sparing surgery with laparoscopic temporary ligation of the uterine arteries and uterine aspiration was indicated. These procedures were performed without complications. The histopathological report of the aspirated tissue was trophoblastic tissue associated with vascular ectasia. CONCLUSION: Temporary laparoscopic ligation of the uterine arteries is an effective procedure in selected cases for vascular control during removal of the remaining trophoblastic tissue, in cases of pregnancy-related increased myometrial vasculature, with complete recovery of uterine irrigation and preservation of the uterus.

ABSTRACT
Abstract Idiopathic scoliosis is a three-dimensional spinal deformity with axial rotation and lateral inclination with an angle greater than 10º per the Cobb method. The approach to idiopathic scoliosis can be conservative or surgical, depending on the degree of angulation, musculoskeletal development, and age of the child or adolescent. It also depends on the functional impairment resulting from the condition. This study aimed to analyze the impact of video-assisted thoracoscopic surgery in idiopathic scoliosis management. This systematic literature review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol, and its PROSPERO registration number is CRD42022351466. Studies queries occurred from August to September 2022 in the bibliographic databases MEDLINE, The Cochrane Library, and Web of Science. The video-assisted thoracoscopic surgery is a minimally invasive alternative to thoracotomy with significant evolution in recent years. Its main advantages include lower blood loss during the procedure, shorter hospital stays, and improved post-surgical esthetics. Authors mentioned its disadvantages as greater complexity and technological requirement, longer surgical time, and the need for careful selection of the patients per vertebral deviation degree. The use of analgesic and anti-inflammatory drugs was not significantly different between traditional procedures (thoracotomy) and thoracoscopic surgery.
Resumo A escoliose idiopática é caracterizada por um quadro de deformidade tridimensional da coluna vertebral com rotação axial e inclinação lateral com angulação maior que 10º segundo o Método de Cobb. Sua abordagem pode se dar de maneira conservadora ou cirúrgica, a depender do grau de angulação, desenvolvimento osteomuscular e idade da criança ou adolescente acometido, ou ainda, a depender do comprometimento funcional advindo da condição. O objetivo deste estudo foi analisar o impacto da videotoracoscopia na abordagem da escoliose idiopática. Trata-se de uma revisão sistemática de literatura, construída conforme protocolo Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) e registrada no PROSPERO sob número CRD42022351466. A busca por estudos foi realizada entre agosto de 2022 e setembro do mesmo ano, em bancos de dados bibliográficos incluindo MEDLINE, The Cochrane Library e Web of Science. A técnica é uma alternativa minimamente invasiva à toracotomia que apresentou grande evolução nos últimos anos. Destacam-se como principais vantagens a menor perda sanguínea durante procedimento, menor tempo de internação e melhora da estética pós-cirúrgica. Uma das desvantagens citadas pelos autores é a maior complexidade e exigência tecnológica, maior tempo cirúrgico e necessidade de seleção criteriosa dos pacientes, conforme graus de desvio vertebral. O uso de analgésicos e anti-inflamatórios não teve diferença significativa entre os procedimentos tradicionais (toracotomia) ou videotoracoscopia.

OBJECTIVES@#To summarize the open-eruption technique of impacted anterior maxillary teeth, this study reports a technically improved operation on surgical exposure based on dental follicles and evaluates post-treatment periodontal health considering the effect of dental follicles.@*METHODS@#Patients who underwent open-eruption technique with unilateral labially impacted maxillary central incisors were selected. The impacted teeth were assigned to the experimental group, and the contralateral unimpacted maxillary central incisors were assigned to the control group. In the surgical exposure, the new technique makes use of dental follicles to manage the soft tissue, so as to preserve soft tissue for better aesthetic results and healthier periodontal tissue. Tooth length, root length, alveolar bone loss, and alveolar bone thickness were recorded after the therapy.@*RESULTS@#A total of 17 patients with unilateral maxillary central incisor impaction were successfully treated. The tooth length and root length of the two groups showed a statistically significant difference between the impacted and homonym teeth, with a shorter length in the impacted tooth (P<0.05). More labial alveolar bone loss was found in the experimental group compared with that in the control group (P<0.05). The outcomes of the cementoenamel junction width, pa- latal alveolar bone loss, and alveolar bone thickness did not indicate statistical significance between the experimental and control groups (P>0.05).@*CONCLUSIONS@#In the surgical exposure, the new technique uses dental follicles to manage the soft tissue and preserve it for better aesthetic results and healthier periodontal tissues.

@#Committee of Minimally Invasive Cardiovascular Surgery (CMICS) annually investigates the minimally invasive cardiovascular surgery performed by departments of cardiovascular surgery of all hospitals in China of last year, and makes classification and summary according to the operation amount of minimally invasive surgery, regional and hospital distribution, and publishes it on the theme report of China Minimally Invasive Cardiovascular Surgery Conference (CMC). In 2021, CMICS published the 2018-2019 annual data of Chinese cardiovascular surgery in the form of a white paper for the first time in the Chinese Journal of Clinical Thoracic and Cardiovascular Surgery, which attracted great attention from peers. In this statistical report, CMICS will focus on the volume of minimally invasive cardiovascular surgery, regional and hospital distribution in China (excluding Hong Kong Special Administrative Region, Macao Special Administrative Region, and Taiwan Province) in the 2020—2021 for your reference.
ABSTRACT
@#Thoracoscopic minimally invasive technology has been used in mitral valve plasty since 1990s. Totally thoracoscopic mitral valve plasty has the advantages of small trauma, beautiful incision and rapid postoperative recovery. It is favored by more and more patients and cardiac surgeons. However, according to the reports, the proportion of totally thoracoscopic mitral valve surgery in China is still low. Mitral valve plasty via the totally thoracoscopic approach is still controversial in terms of population adaptation, perioperative complications and long-term prognosis. In addition, the technical difficulty and the long training cycle of surgeons also limit the popularization of this technology. By summarizing the existing literature, this paper analyzes the application and development of totally thoracoscopic approach in comparison with the traditional median thoracotomy mitral valve plasty.
ABSTRACT
【Objective】 To explore the clinical efficacy and safety of pelvic floor magnetic and electrical stimulation combined with Kegel exercise training in the treatment of stress urinary incontinence (SUI) after minimally invasive surgery for benign prostatic hyperplasia (BPH). 【Methods】 A total of 52 patients with SUI after minimally invasive surgery for BPH treated during Jan.2016 and Feb.2022 were randomly divided into test group (n=26) and control group (n=26). The test group received pelvic floor magnetic and electrical stimulation and Kegel exercise training, while the control group received Kegel exercise training only. The treatment lasted for 3 months. The scores of International Consultation on Incontinence Modular Questionnaire Short Form (ICIQ-SF), 1 h pad test, International Prostate Symptom Score (IPSS) and Incontinence Quality of Life Questionnaire (I-QoL) were recorded and compared between the two groups before and after treatment. The adverse reactions were observed. 【Results】 The scores of ICIQ-SF, IPSS and I-QoL and 1 h pad test significantly decreased in both groups after treatment (P0.05), but after treatment, the scores of ICIQ-SF,IPSS,I-QoL and 1 h pad test were significantly lower in the test group than in the control group (P<0.05). No severe adverse reactions were observed. 【Conclusion】 Pelvic floor magnetic stimulation combined with Kegel exercise training is safe and effective for SUI after minimally invasive surgery for BPH.
ABSTRACT
In recent years, minimally invasive surgery has been rapidly developed and has become the first choice for the treatment of moderate to severe benign prostatic hyperplasia (BPH). Although it can significantly improve the lower urinary tract symptoms, reduce complications, and enhance security, postoperative sexual dysfunction(SD) is still common, which affects the patients’ quality of life. In this paper, we discuss the incidence rate of SD after BPH surgery, the protection strategy of sexual function, and how to choose reasonable treatment from the perspective of sexual function protection.
ABSTRACT
Objective:To develop a novel, flexible, dual-arm, master-slave digestive endoscopic minimally invasive surgical robot system named dual-arm robotic endoscopic assistant for minimally invasive surgery (DREAMS) and to evaluate its feasibility for endoscopic submucosal dissection (ESD) by using ex vivo porcine stomachs.Methods:A novel endoscopic robot (DREAMS) system was developed which was composed of a flexible two-channel endoscope, two flexible robotic manipulators, a master controller, a robotic arm, and a control system. A total of 10 artificial round-like lesions with diameters ranging from 15 to 25 mm were created (5 in gastric antrum and 5 in gastric body) by using fresh peeled stomach of healthy pigs as the model. Submucosal dissection was performed with the assistance of the DREAMS system by two operators. The main outcome was submucosal dissection speed, and the secondary outcomes included muscular injury rate, perforation rate, and grasping efficiency of the robot.Results:All 10 lesions were successfully dissected en bloc by using the DREAMS system. The diameter of the artificial lesions was 22.34±2.39 mm, dissection time was 15.00±8.90 min, submucosal dissection speed was 141.79±79.12 mm 2/min, and the number of tractions required by each ESD was 4.2 times. Muscular injury occurred in 4/10 cases of ESD. No perforation occurred. Conclusion:The initial animal experiment shows the DREAMS system is safe and effective.
