Whether anatomical segmentectomy can replace lobectomy in the treatment of early-stage lung cancer remains controversial. A large number of studies have been conducted for decades to explore whether pulmonary segmentectomy can treat early-stage lung cancer, which is actually to explore the indications of intentional segmentectomy. With the development of scientific researches, it is found that many characteristics affect the malignancy of lung cancer, and the different grades of each characteristic affect the prognosis of patients. It is worth exploring whether different surgical approaches can be used for early-stage lung cancer with different characteristics and different grades. This article reviews the literature and studies to discuss the advances in indications of segmentectomy for early-stage lung in terms of tumor size, consolidation-to-tumor ratio, pathological classification and tumor location, respectively. The objective of this review is to help thoracic surgeons to objectively and scientifically select the surgical method according to the clinical characteristics of early-stage lung cancer.
Objective To analyze the prognosis and indications of transjugular intrahepatic portosystemic shunt (TIPS) in patients with Budd-Chiari syndrome (BCS). MethodsPatients with primary BCS who received TIPS in the Department of Gastroenterology, West China Hospital of Sichuan University between February 2009 and February 2020 were retrospectively reviewed. The medical history, preoperative imaging, surgical records, and postoperative outpatient follow-up medical records were recorded. The laboratory indexes before and after operation were compared, and the cumulative free from hepatic encephalopathy rate, stent patency rate, and cumulative survive rate were calculated. Cox proportional hazards model was used to analyze the independent risk factors of hepatic encephalopathy, shunt dysfunction and death. Results A total of 48 patients were included. The main indications for TIPS included variceal bleeding (16 cases), refractory ascites (24 cases), and diffuse obstruction of hepatic vein with acute liver function impairment (8 cases). The cumulative 1 year, 2 years and 3 years of free from hepatic encephalopathy rates were 92.3%, 89.2% and 85.3%, respectively. The stent patency rates were 89.7%, 72.2% and 54.8% at postoperative 1 year, 3 years and 5 years, respectively. The cumulative survival rates were 86.0%, 79.5% and 71.4% at postoperative 1 year, 3 years and 5 years, respectively. Conclusion TIPS can achieve good efficacy in patients with BCS, and most patients receive TIPS for portal hypertension complications rather than acute liver function impairment.
ObjectiveTo analyze the short- and long-term therapeutic effects of heart transplantation in children. MethodsA retrospective study was conducted on recipients and donors who underwent heart transplantation at the 7th People’s Hospital of Zhengzhou from May 2018 to August 2023, analyzing their clinical characteristics, surgical data, postoperative complications, and survival rates. ResultsA total of 22 children underwent heart transplantation, including 14 males and 8 females, with a median age of 13.5 (10.0, 15.0) years and a median weight of 41.9 (30.5, 55.4) kg. The primary diseases included: dilated cardiomyopathy in 16 patients, hypertrophic cardiomyopathy in 1 patient, myocardial dysplasia in 3 patients, right ventricular dysplasia in 1 patient, and congenital heart disease with abnormal coronary artery origin in 1 patient. The median age of the donors was 21.0 (13.0, 29.0) years, and the median weight was 50.5 (47.3, 75.0) kg. The blood types of the donors and recipients were the same, with type A in 10 patients, type B in 5 patients, type O in 5 patients, and type AB in 2 patients. Before transplantation, all children had a New York Heart Association cardiac function grade Ⅳ, with 1 patient assisted by intra-aortic balloon pump (IABP), 3 patients assisted by extracorporeal membrane oxygenation (ECMO), 2 patients assisted by continuous renal replacement therapy (CRRT), and 2 patients on mechanical ventilation. Nine patients met the criteria for emergency child status allocation, and the panel reactive antibody level in the patients was<10%. The median cold ischemic time of the donor heart was 355.0 (262.0, 395.5) min, the median aortic cross-clamping time was 45.0 (38.3, 51.3) min, the median mechanical ventilation time was 22.5 (16.8, 52.5) h, the median postoperative hospital stay was 29.5 (20.0, 43.0) d, and the median intensive care unit stay was 6.0 (5.0, 8.3) d. After surgery, 4 patients were assisted by ECMO, 2 patients by CRRT, and 7 patients developed complications, including lung fungal infection in 6 patients, liver and kidney dysfunction in 1 patient, local wound non-union and mediastinal infection in 1 patient, and multiple organ failure in 1 patient. Kaplan-Meier curve analysis showed that the survival rates of children after surgery were 91.3% at 1 year and 3 years; the survival rates of adult heart transplant recipients at our center were 86.7% and 73.8% at 1 year and 3 years, respectively, indicating that the survival rate of children with heart transplantation was higher than that of adult patients. ConclusionHeart transplantation is an effective treatment for end-stage heart failure in children, and the short- and long-term survival rates of children with heart transplantation are superior to those of adults. There are still many difficulties to be solved in pediatric heart transplantation, requiring joint efforts from society and the medical community.
ObjectiveTo explore the vascular conditions and the necessity of vascular reconstruction in the treatment of chronic ischemic diseases of lower extremities with tibial transverse transport (TTT) from the perspective of vascular surgery.MethodsA clinical data of 59 patients with chronic ischemic disease of lower extremities treated by TTT between February 2014 and July 2019 were analyzed retrospectively. Among them, there were 41 patients with diabetic foot (DF), including Wagner grade 3-4, Texas grade 2-3, and stage B-D lesions; the disease duration ranged from 0.7 to 2.4 years, with an average of 1.5 years, and 5 cases complicated with arteriosclerosis obliteran (ASO). There were 14 patients with ASO (Fontaine stage Ⅳ and Rutherford stage Ⅲ-Ⅳ) with an average disease duration of 10.8 months (range, 1.5-23.4 months). There were 4 patients with thromboangiitis obliteran (TAO) with an average disease duration of 12.3 months (range, 2.1-18.2 months), and the clinical stages were all in the third stage. In 18 patients that ankle brachial index (ABI) of anterior or posterior tibial artery was less than 0.6 before operation, or the blood flow of the three branches of inferior anterior tibial artery did not reach the ankle by imaging examination, vascular reconstruction was performed before TTT (5 cases of DF combined with ASO, 12 of ASO, 1 of TAO). After operation, the effectiveness was evaluated by ulcer wound healing, skin temperature, pain visual analogue scale (VAS) score, ABI, and CT angiography (CTA) examination.ResultsThe patients with DF were followed up 8-16 months (mean, 12.2 months); the ulcer wounds healed with a healing time of 5.1-9.2 weeks (mean, 6.8 weeks); CTA examination showed that the branches of inferior anterior tibial artery were opened in 5 patients after revascularization; and the tibial osteotomy healed for 5-14 weeks (mean, 8.3 weeks). The patients with ASO were followed up 13-25 months (mean, 16.8 months); the ulcer wounds healed with a healing time of 6.2-9.7 weeks (mean, 7.4 weeks). CTA examination showed that the branches of inferior anterior tibial artery were opened in 12 patients after revascularization; all tibial osteotomy healed, and the healing time was 4.5-14.4 weeks (mean, 10.2 weeks). The patients with TAO were followed up 12-23 months with an average of 12.3 months, and toe/limb amputation was performed after ineffective treatment. The patients were divided into two groups according to whether they were combined with revascularization or not. The ABI, VAS score, and skin temperature in the combined revascularization group significantly improved at 6 months after operation (P<0.05); while there was no significant difference in ABI at 6 months after operation in the TTT group (P>0.05), but the skin temperature and VAS scores significantly improved when compared with those before operation (P<0.05).ConclusionThe ABI of anterior or posterior tibial artery is more than 0.6, radiological examination shows that at least one of the three branches of inferior anterior tibial artery leads to ankle artery, which is a prerequisite for successful TTT in the treatment of chronic ischemic disease of lower extremities. DF is the indication of TTT. ASO can choose TTT, and TAO should use this technique cautiously.
Objective To approach the convenient prediction methods about surgical indications of adhesive ileus. Methods Two thousand and thirtyfour patients with adhesive ileus were analyzed retrospectively between January 1996 and January 2010 in the Department of General Surgery, The First Affiliated Hospital of Anhui Medical University， and 1 992 patients were included into this model. Seventeen factors which could influence the surgical decisions, including period of intestinal obstruction (X1), frequency of attack (X2), history of operation on abdominal region (X3), continuous and severe abdominal pain (X4), severe or frequent vomiting (X5), severe abdominal distention (X6), hemafecia (X7), fever (X8), heart rate (X9), shock or hypotension (X10), touching a swell ansa intestinalis (X11), hypoactive bowel sound (X12), peritonitis (X13), white blood cell (WBC) count of peripheral blood (X14), obstruction ansa interstinalis fixation and a severe expansion by abdominal erect position plain film (X15), peritoneal cavity free air (X16), and seroperitoneum whether or not by B ultrasonic examination (X17) were analyzed by binary logistic regression. Then prediction schedule whether patients with adhesive ileus needed emergency operation was gained by the theory of logistic regression analysis. Results Eight items were included in the prediction model by the method of forward stepwise which were X1, X2, X4, X9, X13, X14, X15, and X17, respectively. The probability of operation could be calculated by the following formula: logit(P)=expZ/（1+expZ）, where, Z={-7.813+〔-1.942×X1(1)/2.290×X1(2)/2.765×X1(3)〕+2.801×X2+2.692×X4+10.610×X9(1)/13.279×X9(2)+3.422×X13+〔-3.048×X14(1)/16.992×X14(2)〕+6.113×X15+2×X17}， which X1（1）, X1（2）, and X1（3） were periods of intestinal obstruction 3－5 d, 5－7 d, and ≥7 d, respectively. X9(1) and X9(2) were heart rates of 60－100/min and ≥100/min, respectively. X14(1) and X14(2) were WBC counts of peripheral blood of (10-20)×109/L and ≥20×109/L， respectively. The patient had to accept surgical procedure when the value of P was more than 0.5. The coincidence was 99.00%, sensitivity was 96.17%, specificity was 99.53% in 1 992 patients. The coincidence was 96.20%, sensitivity was 90.00%, specificity was 96.84% in 105 patients between January 2010 and April 2010 in this hospital. Conclusion The prediction schedule is a good useful value, but the coefficients is corrected following the cases increasing.
Objective To introduce summarily and discuss current controversial problems in terms of necessity and methods of preoperative biliary drainage for patients with malignant biliary obstruction diseases. Method The relevant domestic and international literatures in recent years were reviewed and summarized, and the basis, pros and cons, selectable ways, and current controversy of preoperative biliary drainage were analyzed. Results With development of the research, the view of preoperative biliary drainage also has been changed continuously. At the present time, the main arguments focus on the necessity, timing, biliary decompression way of preoperative biliary drainage and corresponding surgical opportunity after biliary drainage. Incorrect patient selection and undue pursuit of preoperative biliary drainage would be completely opposite to the treatment of malignant biliary obstruction. Conclusions It is generally recommended that preoperative biliary drainage in patients with malignant biliary obstruction diseases is not needed and surgery is performed directly. For patients who have indications of preoperative biliary drainage, it could make patients spend perioperative period smoothly if a reasonable way of biliary decompression is chosen. However, it is necessary to take some large sample retrospective analyses or prospective studies for exploring existing problems of preoperative biliary drainage in future.
ObjectiveTo review the research progress of indication and treatment of graft in shoulder superior capsular reconstruction (SCR) for rotator cuff tear (RCT).MethodsThe literature related to shoulder SCR in recent years was extensively reviewed, and the anatomy, biomechanics, surgical indications, and treatment of graft in SCR were summarized.ResultsSuperior capsule plays a role as a functional complex with rotator cuff, ligament, and whole capsule. SCR can effectively restore the superior stability of the shoulder. The indications of SCR include the irreparable massive RCT, massive RCT combined with pseudoparalysis shoulder, medium/large RCT with severe degenerative rotator cuff tissue, and dual-layer RCT. In order to achieve a better healing of tendon-bone in graft and decrease the rate of long-term graft retearing, it is essential to select an appropriate thickness graft, fix the graft in right intensity, and get a better capsular continuity.ConclusionThe technique of SCR advanced to SCR for reinforcement and it is indicated from substantial massive RCT to severe degeneration of rotator cuff tissue. Graft treatment is the key step for a successful SCR.
Mitral regurgitation (MR) is the most common type of valvular heart disease. Mitral valve repair/replacement can improve the prognosis of patients with severe MR, but a large proportion of patients cannot tolerate surgical procedures due to comorbidities and surgical risks. Transcatheter mitral valve replacement (TMVR) is a kind of treatment for mitral valve disease in which an artificial valve is delivered to the mitral valve annulus through a catheter and released into place, with the advantages of no thorax opening, less trauma and high safety. Early clinical studies of TMVR have shown good results, but still face many challenges. Strict indications are effective measures to reduce surgical risks and postoperative complications. This article explores the relevant indications of TMVR by analyzing several studies at home and abroad.
To standardize the treatment of secondary hyperparathyroidism and effectively meet the needs of practical clinical work, we gathered experts and nursing experts from Departments of Thyroid Surgery, Nephrology, Endocrinology and Metabolism, Nuclear Medicine, Ultrasound, Anesthesiology, Cardiology, and other departments at West China Hospital of Sichuan University to solicit opinions. This consensus was finally established based on published guidelines and the best evidence in Chinese and English combined with clinical practice. This consensus is intended to summarize and conclude, to the greatest extent possible, the practical issues encountered in diagnosing and treating secondary hyperparathyroidism in perioperative settings and to provide recommendations for clinical practice.
Objective To investigate the appropriate indication about removing abdominal drainage after pancreaticoduodenectomy. Method The clinical data of 156 patients who underwent pancreaticoduodenectomy in our hospital from January 2014 to June 2016 were analyzed retrospectively. The patients were divided into two groups, with 76 patients in the enhanced recovery after surgery (ERAS) group and 80 patients in the control group according to the type of indications about removing abdominal drainage. The time of removing abdominal drainage, hospital stay, incidence of postoperative complications, and readmission rate during 30 days after surgery were compared between the2 groups. Results Compared with the control group, the time of removing abdominal drainage 〔(6.2±2.5) dvs. (10.8±2.2) d,P<0.001〕and hospital stay〔(11.8±3.4) dvs. (15.7±3.6) d,P<0.001〕 of the ERAS group were both shorter, incidence of abdominal infection was lower〔1.3% (1/76)vs. 10.0% (8/80), P=0.020〕 , but there was no significant difference in the incidence of postoperative pancreatic fistula 〔18.4% (14/76) vs. 21.3% (17/80)〕 , delayed gastric emptying〔1.4% (1/76) vs. 7.5% (6/80)〕 , and the readmission rate during 30 days after surgery〔5.3% (4/76) vs. 3.8% (3/80)〕 , P>0.05. Conclusions Indications about removing abdominal drainage after pancreaticoduodenectomy by authors are safe.
