Reflection and practice of long-term management of hepatocellular carcinoma / 中华消化外科杂志

The treatment of hepatocellular carcinoma (HCC) has always been a hot spot of medical research worldwide. At present, surgical resection is the main therapy for HCC, supplemen-ted by interventional therapy, chemotherapy, radiotherapy, etc. Although the overall survival of HCC has been significantly improved in recent years, the overall effect is still unsatisfactory. New systemic therapeutic drugs are constantly emerging and applied to clinical practice, which bring new opportunities and challenges for the treatment of HCC. However, too many diagnosis and treatment topics bring obvious contradiction between the division system and the orderly and standardized HCC treatment. In the future, how to realize unified and standardized homogeneous diagnosis and treatment is the key problem to be solved urgently. The authors summarize the current status of diagnosis and treatment of HCC and propose the long-term management concept for HCC according to their own clinical experience and the current advances of the diagnosis and treatment at home and abroad, and carry out new practice and investigation on the patients with HCC by constructing a hepatobiliary multi-technical team.

[The effect of age on the degree of strength restoration of the lower limb musles in the long-term period after surgical treatment of adult patients with spondylolisthesis.]

The purpose of the work was to study the effect of age on the degree of isometric strength restoration of the lower limb muscles in the long-term period after surgical treatment of adult patients with spondylolisthesis. 36 patients with spondylolisthesis of I and II displacement degree and 50 normal subjects at the age of 41-66 years were included in the study. Maximum moments of the femur and leg isometric strength were studied using dynamometric stands. The pain syndrome was evaluated in all the patients (VAS scale), as well as their functional condition (Oswestry scale). The investigations were performed before treatment and 75-99 months after surgical intervention. The presented reliable reverse correlation of the patient's age and the pattern and magnitude of changes in the strength of the lower limb muscles was identified in adult patients with spondylolisthesis in the long-term period after surgical treatment. At the younger age (41-59 years) positive dynamics of the muscle strength prevailed - an increase in 56,3% cases, conformity to the preoperative level was observed in 6,3% patients, a decrease in muscle function - in 37,4% cases. In the age-related group of 60-74 years the muscle strength growth was recorded only in 16,7% cases, there was no dynamics relative to the initial level in 8,3% patients, and a decrease in maximum moment of strength was observed in 75% cases. Thus, in case of large intervals of the follow-up period of the results of surgical treatment of adult patients with spondylolisthesis it is impossible to avoid evaluating the effect of age changes in muscles on the degree of restoring isometric strength of the lower limb muscles. As far as age increases, the reserves for muscle function improvement after surgical treatment are reduced significantly.

[Ten-year results of abdominal aortic and great vessels aneurysms management]. / Desiatiletnie rezul'taty lecheniia bol'nykh s anevrizmami briushnoi aorty i magistral'nykh arterii.

AIM: To present own 10-year experience of abdominal aortic and great vessels aneurysms management. MATERIAL AND METHODS: There were 369 patients with abdominal aortic aneurysms (AAA) for the period 1995-2016 at the Yaroslavl Regional Clinical Hospital. 25% of patients suffered from abdominal aortic and great vessels aneurysms. Mean age was 70.3±7.5. There were 79 (86%) men and 13 (14%) women. 93 patients had 212 aneurysms of other sites besides AAA (from 1 to 6 aneurysms in each case). 63 (68%) patients have been treated and followed-up for the period from 1 to 10 years (mean 105±11.8 months). RESULTS: 1-, 5-, 8- and 10-year survival after AAA repair was 98%, 81%, 54% and 38% respectively. CONCLUSION: The common complications of great vessels aneurysms are distal thrombosis and embolism (40%). Ruptures of aneurysms are less common (13%). These complications require active surgical tactics that allows to preserve the limbs in 85% of patients. Progressive nature of disease in overwhelming numbers of patients (95%) with aneurysms enlargement and their occurrence in other sites requires regular lifelong clinical examination with mandatory ultrasound 2 times per year.

Functionally univentricular heart and the fontan operation: lessons learned about patterns of practice and outcomes from the congenital heart surgery databases of the European association for cardio-thoracic surgery and the society of thoracic surgeons.

BACKGROUND: "The term "functionally univentricular heart" describes a spectrum of congenital cardiovascular malformations in which the ventricular mass may not readily lend itself to partitioning that commits one ventricular pump to the systemic circulation and another to the pulmonary circulation." The purpose of this article is to review patterns of practice and outcomes in the Congenital Heart Surgery Databases (CHSDBs) of the European Association for Cardio-Thoracic Surgery (EACTS) and the Society of Thoracic Surgeons (STS) in patients with functionally univentricular hearts undergoing the Fontan operation. METHODS: We examined all index operations performed on patients with functionally univentricular hearts in the EACTS and STS-CHSDBs over 4 years from 2007 to 2010, inclusive. RESULTS: The most common diagnostic categories are hypoplastic left heart syndrome, tricuspid atresia, and double inlet left ventricle. The Fontan operation makes up 3.2% of all cardiac operations in the EACTS and STS-CHSDBs over 4 years from 2007 to 2010, inclusive. Of all the patients undergoing a Fontan procedure, 65.1% had an extracardiac Fontan, 21.5% had a lateral tunnel, and 5.8% had a Fontan revision or conversion (Re-do Fontan). In operations where fenestration status is known, 68.5% of the Fontan operations were fenestrated. During the four years of this analysis, only 5 patients had ventricular septation. Exclusive of Fontan revision or conversion (Re-do Fontan), all remaining Fontan operations had a discharge mortality of 2.3%. Fontan revision or conversion (Re-do Fontan) had a discharge mortality of 12.8%. CONCLUSIONS: The STS database is largest CHSDB in North America. The EACTS database is largest CHSDB in Europe. This review of data from EACTS and STS allows for unique documentation of practice patterns and outcomes. From this analysis, it is clear that patients with functionally univentricular hearts present a challenging problem; however, exclusive of Fontan revision or conversion (Re-do Fontan), the Fontan operation has a discharge mortality of 2.3%.

Embolização das artérias uterinas com partículas de PVA-PVAC esférico como preparo para posterior ressecção cirúrgica de miomas / Uterine artery embolization with spherical pva-pvac particles as preparation for surgical resection of miyomas

OBJETIVO: avaliar a utilização de uma nova partícula de polivinil álcool e polivinil acetato (PVA-PVAc) esférica, para embolização das artérias uterinas, em pacientes portadoras de mioma, com indicação cirúrgica. MÉTODOS: doze pacientes foram submetidas à embolização de miomas uterinos com partículas de PVA-PVAc. Três a nove meses depois, realizou-se uma laparotomia com miomectomia. Analisaram-se os seguintes parâmetros: volume do útero e do maior mioma; concentrações do hormônio folículo estimulante e de hemoglobina; sangramento menstrual (número de dias e de absorventes utilizados), sinais e sintomas antes do tratamento, após a embolização e após a miomectomia. RESULTADOS: a média de idade foi 37 anos e a média do volume uterino, previamente ao tratamento, de 939,3cc. Três anos após a embolização, observou-se diminuição do volume uterino (p=0,0005). Houve melhora na concentração de hemoglobina (p= 0,0004), com elevação após a embolização, sem variação subsequente à miomectomia. Não ocorreu variação significante do hormônio folículo estimulante, (p=0,17). Não foi constatado nenhum caso de falência ovariana, mas uma das pacientes apresentou atrofia de endométrio. Duas pacientes engravidaram, com bons indicadores obstétricos. Quanto aos sinais e sintomas, houve melhora após a embolização, que se manteve após a miomectomia. CONCLUSÃO: a embolização arterial com partículas de PVA-PVAc esférico mostrou-se promissora no preparo para uma intervenção cirúrgica com retirada dos miomas, pois, associou-se à redução do volume uterino, à diminuição do sangramento operatório e tornou possível a utilização de incisões menores, aumentando a chance de preservação do útero.

OBJECTIVE: To evaluate the use of a new spherical particle of polyvinyl alcohol and polyvinyl acetate (PVA-PVAc) for uterine artery embolization in patients with myoma with surgical indication. METHODS: twelve patients underwent uterine myoma embolization with PVA-PVAc particles. Three to nine months later, they were submitted to laparotomy with myomectomy. We analyzed the following parameters: volume of the uterus and of the bigger myoma; concentrations of follicle stimulating hormone and hemoglobin; menstrual bleeding (number of days and used absorbents), signs and symptoms before treatment, after embolization and after myomectomy. RESULTS: The mean age was 37 years and mean uterine volume prior to treatment, 939.3 cc. Three years after embolization, there was reduction in uterine volume (p = 0.0005), increase in hemoglobin concentration after embolization (p = 0.0004), without variation after the myomectomy. There was no significant variation of the follicle stimulating hormone (p = 0.17). There was no case of ovarian failure, but one of the patients had endometrial atrophy. Two patients became pregnant, with good obstetric indicators. Signs and symptoms improved after embolization, and remained after myomectomy. CONCLUSION: Arterial embolization with spherical PVA-PVAc particles is promising in the preparation for myoma surgery, since it was associated with a reduction in uterine volume, decrease in intraoperative bleeding and made possible the use of smaller incisions, increasing the chance of preserving the uterus.

Transposition of the great arteries: lessons learned about patterns of practice and outcomes from the congenital heart surgery database of the society of thoracic surgeons.

The Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database contains data about 3258 patients with the diagnosis of transposition of the great arteries (TGA) who underwent surgery during the 4-year time interval from July 1, 2005 to June 30, 2009, inclusive. This cohort includes 2918 patients with concordant atrioventricular connections and discordant ventriculoarterial connections and 341 patients with congenitally corrected TGA (discordant atrioventricular connections and discordant ventriculoarterial connections). The 4 most common operations were the following: (1) arterial switch operation (ASO) for TGA with intact ventricular septum (n = 1196), (2) ASO with ventricular septal defect (VSD) repair for TGA with VSD (n = 420), (3) ASO with VSD repair and aortic arch repair for TGA with VSD and hypoplastic arch (n = 55), and (4) Rastelli operation for TGA with VSD and left ventricular outflow tract obstruction (n = 49). Detailed preoperative, intraoperative, and postoperative data were obtained about patients who underwent these 4 operations. Median age at surgery (days) was as follows: ASO: 6.0; ASO with VSD repair: 7.0; ASO with VSD repair and aortic arch repair: 7.0; and Rastelli: 309.0. Mean age at surgery (days) was as follows: ASO: 22.9; ASO with VSD repair: 24.8; ASO with VSD repair and aortic arch repair: 14.4; and Rastelli: 721.8. Discharge mortality was as follows: ASO: 2.2%; ASO with VSD repair: 5.5%; ASO with VSD repair and aortic arch repair: 7.3%; and Rastelli: 0%. Median length of stay (days) was as follows: ASO: 11.0; ASO with VSD repair: 11.0; ASO with VSD repair and aortic arch repair: 18.0; and Rastelli: 7.0. The sternum was left open in the following: ASO: 24.8%; ASO with VSD repair: 29.5%; ASO with VSD repair and aortic arch repair: 40.0%; and Rastelli: 6.1%. This review of data from the STS Congenital Heart Surgery Database allows for unique documentation of patterns of practice and outcomes. From this review, we learned that although surgery for TGA is often complex and may be associated with morbidity, most patients survive without major complications.

Heterotaxy: lessons learned about patterns of practice and outcomes from the congenital heart surgery database of the society of thoracic surgeons.

According to The International Society for Nomenclature of Pediatric and Congenital Heart Disease (ISNPCHD), "Heterotaxy is synonymous with 'visceral heterotaxy' and 'heterotaxy syndrome'. Heterotaxy is defined as an abnormality where the internal thoraco-abdominal organs demonstrate abnormal arrangement across the left-right axis of the body. By convention, heterotaxy does not include patients with either the expected usual or normal arrangement of the internal organs along the left-right axis, also known as 'situs solitus', or patients with complete mirror-imaged arrangement of the internal organs along the left-right axis also known as `situs inversus'." or patients with complete mirror-image arrangement of the internal organs along the left-right axis, also known as situs inversus. The purpose of this article is to review the data about heterotaxy in the Society of Thoracic Surgeons (STS) Congenital Heart Surgery Database. The investigators examined all index operations in the STS Congenital Heart Surgery Database over 12 years from January 1, 1998 to December 31, 2009, inclusive. This analysis resulted in a cohort of 77 153 total index operations. Of these, 1505 operations (1.95%) were performed in patients with heterotaxy. Of the 1505 index operations performed in patients with heterotaxy, 1144 were in patients with asplenia and 361 were in patients with polysplenia. In every STS -EACTS Congenital Heart Surgery Mortality Category, discharge mortality is higher in patients with heterotaxy compared with patients without heterotaxy (EACTS = European Association for Cardio-Thoracic Surgery). Discharge mortality after systemic to pulmonary artery shunt is 6.6% in a cohort of all single-ventricle patients except those with heterotaxy, whereas it is 10.8% in single-ventricle patients with heterotaxy. Discharge mortality after Fontan is 1.8% in a cohort of all single-ventricle patients except those with heterotaxy, whereas it is 4.2% in single-ventricle patients with heterotaxy. The STS Congenital Heart Surgery Database is largest congenital heart surgery database in North America. This review of data from the STS Congenital Heart Surgery Database allows for unique documentation of practice patterns and outcomes. From this analysis, it is clear that heterotaxy is a challenging problem with increased discharge mortality in most subgroups.

Polytetrafluoroethylene bicuspid pulmonary valve implantation: experience with 126 patients.

This article reports our initial experience in 126 consecutive patients treated with placement of a surgically created polytetrafluoroethylene (PTFE) bicuspid pulmonary valve at The Congenital Heart Institute of Florida (CHIF). A bicuspid pulmonary valve is created with PTFE and sutured into the right ventricular outflow tract. PTFE bicuspid pulmonary valves were placed in 126 patients (age: range, 3.1-64.7 years, mean, 17.9 years; weight: range, 14.2-113.6 kg, mean, 55.4 kg). All patients had pulmonary insufficiency, pulmonary stenosis, or both, most commonly after previous repair of tetralogy of Fallot (71 patients). Follow-up was up to 8.3 years (range, 0-8.3 years, mean, 3.34 years). Operative mortality was 1 patient (0.8%). Late mortality was non-valve-related in 3 patients (2.4%). The initial 84 patents in this series received valves constructed from PTFE with 0.6-mm thickness. The next 42 patients received valves constructed from PTFE with 0.1-mm thickness. Six patients of 126 (4.8%) required replacement of the PTFE bicuspid pulmonary valve because of immobile and calcified leaflets. All 6 who required replacement of the PTFE bicuspid pulmonary valve initially received a valve constructed from porous 0.6-mm PTFE material. We currently use nonporous 0.1-mm PTFE, which does not allow cellular in-growth and thickening. Early echocardiographic follow-up of these valve leaflets made with 0.1-mm PTFE has demonstrated improved leaflet mobility and pliability and lower transvalvar gradients. PTFE bicuspid pulmonary valve implantation is safe and effective and demonstrates acceptable performance for the intermediate term. It is anticipated that using thinner 0.1-mm PTFE will improve valve function and durability. Long-term follow-up is necessary to determine the true value of this technique.

Atrioventricular septal defects: lessons learned about patterns of practice and outcomes from the congenital heart surgery database of the society of thoracic surgeons.

During the 4-year time interval of 2005 through 2008, the Society of Thoracic Surgeons Congenital Heart Surgery Database documented data about 2882 operations to repair atrioventricular (AV) canal defects: partial, 623 (21.5%); intermediate, 342 (11.8%);. complete, 1917 (66.3%). Mean age at complete repair (years) was as follows: partial, 6.1; intermediate, 2.9; complete, 0.6. Median age at complete repair (years) was as follows: partial, 2.6; intermediate, 0.9; complete, 0.4. Down syndrome was present in 1767 patients (61.1%). Debanding of the pulmonary artery was rarely performed: partial, 1 (0.2%); intermediate, 0 (0.0%); complete, 66 (3.4%). Deep hypothermic circulatory arrest was rarely used: partial, 6 (1.0%); intermediate, 5 (1.5%); complete, 52 (2.7%). Discharge mortality was low: partial, 2 (0.3%); intermediate, 3 (0.9%); complete, 38 (2.0%). Atrioventricular block requiring permanent pacemaker occurred but was uncommon: partial, 6 (1.0%); intermediate, 2 (0.6%); complete, 29 (1.5%). Unplanned reoperation prior to hospital discharge occurred in 3.9% of complete AV canal repairs. The sternum was left open in 3.0% of complete AV canal repairs. Postoperative cardiac arrest occurred in 1.9% of complete AV canal repairs. Mean postoperative length of stay (days) was as follows: partial, 5.2; intermediate, 7; complete, 13.1. Median postoperative length of stay (days) was as follows: partial, 4; intermediate, 4; complete, 7. This review of data from the Society of Thoracic Surgeons Congenital Heart Surgery Database allows for unique documentation of patterns of practice and outcomes. From this review, we learned that 98% to 99% of patients survive complete repair of AV canal and 96% to 97% survive complete repair of AV canal with no major complications.

A Study on the Changes of the Femoral Head following Treatment of Congenital Dislocation of the Hip / 대한정형외과학회잡지

Although the incidence of avascular necrosis of the pmximal end of the femur has declined by early diagnosis and gentle dynamic reduction, it is still one of the major complication in treatment of congenital dislocation of the hip. From 65 cases, followed up at least one year after reduction at the Department of Orthopaedic Surgery, Busan National University Hospital from January, 1980 to June, 1984, the authom studied the factom causing avascular necrosis of the femoral head and its radiographic classification. The following results were obtained. 1. Based on Salter's criteria, avascular necrosis of the femoral head was considered in 16 of the 65 hips, a rate of 24.6%. 2. Based on the classification of Bucholz and Ogden, radiographic patterns of avascular necrosis were: type 1, 6(37.5%); type 2,3(18.8%); type 3, 5(31.3%); type 4, 2(12.5%). 3. Generally, the older the child when treatment was initiated, the more likely was avascular necrosis to develop, and the more severe was its damage. 4. The incidences of avascular necrosis in various treatments were: Pavlik harness, 10%; manipulative reduction, 17%; medial approach open reduction 40%; Salters innominate osteotomy only, 36%; femoral osteotomy with pelvic osteotomy, 20%. The high incidence in medial approach open reduction and Salters innominate osteotomy may be due to failure of previous manipulative reduction. 5. The preliminary traction of 14 days or more substantially reduced the incidence of avascular necrosis. 6. There was particularly high incidence of avascular necrosis in cast immobilization of Lorenz position. 7. The correlation between adductor tenotomy and avascular necrosis was not noticed. There was no avascular necrosis in the normal contralateral hip after cast immobilization.
