ABSTRACT
Objective To investigate the diagnosis and treatment strategy of the portal vein complications in children undergoing split liver transplantation. Methods The clinical data of 88 pediatric recipients who underwent split liver transplantation were retrospectively analyzed. Intraoperative anastomosis at the bifurcating site of the portal vein or donor iliac vein bypass anastomosis was performed depending on the internal diameter and development of the recipient's portal vein. A normalized portal venous blood stream monitoring was performed during the perioperative stage. After operation, heparin sodium was used to bridge warfarin for anticoagulation therapy. After portal vein stenosis or thrombosis was identified with enhanced CT or portography, managements including embolectomy, systemic anticoagulation, interventional thrombus removal, balloon dilatation and/or stenting were performed. Results Among the 88 recipients, a total of 10 children were diagnosed with portal vein complications, of which 4 cases were diagnosed with portal vein stenosis at 1 d, 2 months, 8 months, and 11 months after surgery, and 6 cases were diagnosed with portal vein thrombosis at intraoperative, 2 d, 3 d (n=2), 6 d, and 11 months after surgery, respectively. One patient with portal vein stenosis and one patient with portal vein thrombosis died perioperatively. The fatality related to portal vein complications was 2% (2/88). Of the remaining 8 patients, 1 underwent systemic anticoagulation, 2 underwent portal venous embolectomy, 1 underwent interventional balloon dilatation, and 4 underwent interventional balloon dilatation plus stenting. No portal venous related symptoms were detected during postoperative long term follow up, and the retested portal venous blood stream parameters were normal. Conclusions The normalized intra- and post-operative portal venous blood stream monitoring is a useful tool for the early detection of portal vein complications, the early utilization of useful managements such as intraoperative portal venous embolectomy, interventional balloon dilatation and stenting may effectively treat the portal vein complications, thus minimizing the portal vein complication related graft loss and recipient death.
ABSTRACT
Ureteral stricture in renal allografts is one of the common postoperative complications in kidney transplant recipients. Due to short ureter in renal allografts, endovascular treatment should be adopted before reconstruction surgery to avoid irreversible injury. Alleviating renal allograft injury, easing obstruction or establishing drainage channel are the key measures to treat ureteral stricture. In endovascular treatment, balloon dilatation and internal incision yield high recurrence rate, and long-term indwelling of self-expanding metallic ureteral stents may be a better option. Compared with traditional stents, metallic stents may maintain urinary tract patency for a long time and mitigate the irritation of lower urinary tract symptoms,with different indications and efficacy. Although all metallic stents may be displaced and occluded, it still plays a positive role in the treatment of ureteral stricture in renal allografts. In this article, the application of self-expanding metallic ureteral stent in ureteral stricture of renal allografts was mainly illustrated, aiming to provide reference for optimizing the treatment of ureteral stricture in renal allografts.
ABSTRACT
【Objective】 To evaluate the efficacy and safety of ureteroscope or flexible ureteroscope combined with balloon dilatation in the treatment of ureteral stricture with renal calculi in transplanted kidney. 【Methods】 The clinical data of 9 patients treated in our hospital during 2016 and 2022 were reviewed. The changes of the width of hydronephrosis, levels of creatinine and urea nitrogen, reoperation, and re-dwelling of stents were analyzed. 【Results】 One patient failed the operation because the guide wire could not be inserted, and the other 8 patients successfully completed the surgery. The stents were removed 6 to 8 weeks after surgery. During the follow-up of 8 to 48 months, no recurrence of renal calculi occurred; 5 patients had no recurrence of ureteral stricture; 3 patients (cases 4, 6, 9) underwent regular ureteral stent replacement due to hydronephrosis; the width of hydronephrosis, creatinine and urea nitrogen levels of 8 patients were significantly improved (P<0.05). 【Conclusion】 Ureteroscope/flexible with balloon dilatation is safe and effective in the treatment of transplanted kidney with ureteral stricture and kidney stones.
ABSTRACT
Objective:To compare the clinical efficacy between 3D printing-assisted percutaneous balloon dilatation calcaneal plasty (3D-PCP) and conventional open reduction and internal fixation (ORIF) via the extended lateral L-shaped approach in the treatment of osteoporotic calcaneal fractures of Sanders type Ⅱ or Ⅲ in the elderly patients.Methods:Retrospectively analyzed were the data of 36 elderly patients with osteoporotic calcaneal fracture of Sanders type Ⅱ or Ⅲ who had been surgically treated at Department of Orthopaedics, Yixing People's Hospital from June 2012 to June 2018. According to their treatment methods, the patients were divided into a 3D-PCP group [16 cases, 9 males and 7 females with an age of (73.0 ± 3.4) years] and an ORIF group [20 cases, 8 females and 12 females with an age of (71.4 ± 2.6) years]. The 2 groups were compared in terms of hospital stay, operation time, intraoperative fluoroscopy frequency, suture removal time, weight bearing time, fracture healing time, visual analogue scale (VAS) for the surgical site 2 days and one year after surgery, American Foot and Ankle Surgery Association (AOFAS) ankle-hindfoot score, calcaneal imaging parameters (B?hler angle, Gissane angle, and length, width and height of the calcaneus axis) at 2 days and one year after surgery, and postoperative complications.Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability ( P > 0.05). All patients were followed up for 14 to 18 months (mean, 15.6 months). Compared with the ORIF group, the 3D-PCP group had significantly shorter hospital stay, significantly shorter operation time, significantly earlier suture removal, significantly earlier weight-bearing, significantly lower VAS scores at 2 days after surgery, significantly higher AOFAS ankle-hindfoot scores at one month after surgery, but significantly more times of intraoperative fluoroscopy (all P < 0.05). In all patients, the VAS scores at 2 days after surgery were significantly lower than those before surgery, and those at one year after surgery significantly lower than those at 2 days after surgery ( P < 0.05). In all patients, the AOFAS ankle-hindfoot scores at one month after surgery were significantly higher than those before surgery ( P < 0.001). In the ORIF group, the AOFAS ankle-hindfoot scores at one year after surgery were significantly higher than those at one month after surgery ( P < 0.05), but in the 3D-PCP group there was no such a significant difference between one year and one month after surgery ( P > 0.05). There was no significant difference in VAS score, AOFAS score, fracture healing time or postoperative imaging parameters between the 2 groups at one year after surgery ( P > 0.05). There was no significant difference either in the incidence of complications between the 2 groups ( P > 0.05). Conclusion:In the treatment of osteoporotic calcaneal fractures of Sanders type Ⅱ or Ⅲ in the elderly patients, compared with conventional ORIF, 3D-PCP shows advantages of shorter operation time, minimal invasion, quicker incision healing, shorter hospital stay, earlier weight-bearing exercise, and better functional recovery but a disadvantage of increased times of intraoperative fluoroscopy.
ABSTRACT
Objective:To investigate the risk factors of duodenal papilla hemorrhage after endoscopic papillary balloon dilatation (EPBD) for choledocholithiasis.Methods:Clinical data of 411 cases of choledocholithiasis treated by EPBD in Hangzhou First People′s Hospital from January 2016 to December 2019 were analyzed retrospectively. Based on the development of hemorrhage after EPBD, patients were divided into the hemorrhage group and the non-hemorrhage group. The risk factors of hemorrhage after EPBD were analyzed by single and Logistic regression.Results:Among 411 patients who received EPBD, 29 patients had EPBD-related duodenal papilla hemorrhage and the overall incidence was 7.1%.Univariate analysis showed that there were significant differences between the hemorrhage group and the non-hemorrhage group in diameter≥1.2 cm of balloon dilation ( P=0.001), endoscopic sphincterotomy (EST) ( P=0.002)and the incision length of EST ( P<0.001). Logistic regression analysis showed that the incision length of EST ( OR=69.771, 95% CI: 7.544-645.296, P<0.001) was the independent risk factor for duodenal papilla hemorrhage after EPBD. Diameter≥1.2 cm of balloon dilation( OR=0.192, 95% CI: 0.071-0.524, P=0.001) was a protective factor. Conclusion:The incision length of EST is an independent risk factor of duodenal papilla hemorrhage after EPBD. Endoscopic papillary large balloon dilation is a protective factor for postoperative hemorrhage, which can reduce the incidence of bleeding.
ABSTRACT
Objective:To observe the rehabilitative effect of combining respiratory function training with balloon dilatation for persons with cricopharyngeal achalasia after radiotherapy for nasopharyngeal carcinoma.Methods:A total of 120 nasopharyngeal carcinoma patients with cricopharyngeal achalasia after radiotherapy were randomly divided into an observation group and a control group, each of 60. Both groups were treated with routine functional swallowing training and balloon dilatation, while the observation group was additionally provided with respiratory function training 5 days a week for 8 weeks. Before the treatment and after 4 and 8 weeks of treatment, the swallowing function of both groups was evaluated using video fluoroscopy (VFSS), a functional oral intake scale (FOIS), cricopharyngeal muscle functional status and the M. D. Anderson dysphagia inventory (MDADI).Results:After 4 weeks of treatment the average VFSS, FOIS and MDADI scores of both groups were significantly better than before the treatment, and significant improvement continued over the subsequent four weeks. After 8 weeks of treatment, the average VFSS, FOIS and MDADI scores of the observation group had again improved significantly. Physiology, functioning, and their emotional state were also adjudged to have improved compared with 4 weeks earlier and compared with the control group.Conclusion:Combining respiratory function training with balloon dilatation can improve swallowing and can significantly reduce or delay swallowing disorders among patients with cyclopharyngeal achalasia after radiotherapy.
ABSTRACT
Objective:To explore optimum surgical treatment of ureteral strictures after ureteroscopic holmium laser lithotripsy.Methods:The clinical data of 113 patients with ureteral stricture after ureteroscopic holmium laser lithotripsy from December 2014 to December 2019 were analyzed retrospectively. Of all the patients, there were 73 males and 40 females(aged from 31 to 68) with the mean age of 49 years. The mean length of ureteral stricture was 15mm (from 5mm to 25mm). The mean time since the last holmium laser lithotripsy was 6 months (from 3months to 10 months). According to the different treatment of stenosis, 113 patients were divided into endourological treatment group (34 patients) and reconstruction group(79 patients). According to the different surgical methods, endourological treatment group was divided into ureteral balloon dilatation (18 patients) and ureterotomy (16 patients). Reconstruction group was divided into laparoscopic surgery and open surgery, whose were ureteral stenosis resection and anastomosis. Patients were followed up closely postoperatively. Therapeutic success was defined as disappeared hydronephrosis, and unobstructed anastomosis. Success rate, operation time, postoperative changes of hemoglobin, hospital stay and the incidence of postoperative complications were measured.Results:The follow-up time ranged from 5 months to 53 months, with a median time of 18 months. There was no significant difference in age, sex, BMI, location of ureteral stricture, side of stricture and degree of hydronephrosis between endourological treatment group and reconstruction group( P>0.05). The length of ureteral stricture in reconstruction group was significantly longer than that in endourological treatment group (10.3±4.2 mm vs. 17.2±7.8mm, P<0.001). Although the operation time, postoperative changes of hemoglobin, hospital stay and the incidence of postoperative complications were lower in the endourological treatment group compared to reconstruction group ( P<0.001), the overall success rate of the reconstruction operation was significantly higher than that in endourological treatment group (96.2% vs. 61.8%, P<0.001). Furthermore, there was no significant difference in the success rate between laparoscopic surgery group and open surgery group (95.3% vs.97.2%, P<0.05), and there was no significant difference between the balloon dilatation group and the stenosis internal ureterotomy group (66.7% vs.56.3%, P<0.05).113 cases were followed up for an average of 18 (5-53) months. Conclusions:For the treatment of ureteral stricture after ureteroscopic holmium laser lithotripsy, the success rate of reconstruction group (laparoscopic surgery and open surgery)was significantly higher than that of endourological surgery (balloon dilatation and internal ureterotomy). Reconstruction surgery is the optimum surgical treatment to treat ureteral stricture after ureteroscopic holmium laser lithotripsy.
ABSTRACT
Objective To evaluate the clinical efficacy of percutaneous transluminal angioplasty (PTA) combined with stent implantation in the treatment of transplant renal artery stenosis (TRAS) after renal transplantation. Methods Clinical data of 21 patients with TRAS after renal transplantation undergoing PTA combined with stent implantation were retrospectively analyzed. The incidence of TRAS in renal transplant recipients was summarized. The changes of relevant indexes in patients with TRAS were statistically compared before and after interventional treatment. Clinical prognosis of patients with TRAS was evaluated. Results The incidence of TRAS in renal transplant recipients was 4.1%(21/507). TRAS was diagnosed at postoperative 5 (4, 7) months, and 67% (14/21) of patients developed TRAS within postoperative 6 months. Compared with the values before interventional therapy, the serum creatinine level, systolic and diastolic blood pressure and peak flow velocity of transplant renal artery of patients with TRAS were significantly decreased, and the estimated glomerular filtration rate (eGFR) and interlobar arterial resistance index were significantly increased at 1 week and 1 month after interventional therapy (all P < 0.05). During postoperative follow-up after PTA combined with stent implantation, 1 patient suffered re-stenosis of the transplant renal artery, which was improved after simple balloon dilatation. One patient developed pseudoaneurysm formation at the puncture site of the right femoral artery. One patient presented with renal atrophy and loss of function due to atresia of the transplant renal artery. All the remaining 18 patients were well recovered after surgery. Conclusions PTA combined with stent implantation is the optimal treatment of TRAS after renal transplantation, which can significantly improve the function of transplant kidney and considerably prolong the survival time of transplant kidney.
ABSTRACT
Hypertrophic pyloric stenosis is a congenital disease, presenting within two weeks of birth. However adult idiopathic hypertrophic pyloric stenosis (AIHPS) presents in middle age, predominantly in males and usually without any antecedent cause. Secondary variant may be due to intra gastric causes or extra gastric post-operative adhesions. Patient presents with symptoms of gastric outlet obstruction. Diagnosis depends on clinical, radiological and endoscopic findings. Treatment is subtotal gastrectomy. Pyloroplasty and endoscopic dilatation may be tried in debilitated patients. We present a case of AIHPS presenting as gastric outlet obstruction in a 16 year old female, that was surgically managed with an antrectomy.
ABSTRACT
Background: The objective of the study was to effect of steroids in the long term outcome of esophageal benign stricture after endoscopic balloon dilation in terms of recurrence.Methods: With purposive sampling, 50 cases were taken in these studies who were admitted with strictures at any location along the esophagus and of any size at New Civil Hospital, Surat. The indoor patients for a three year period were retrieved using a prepared case sheet proforma on the basis of the patient’s demographic profile and clinical findings. Patients had undergone endoscopic balloon dilation for esophageal benign stricture. In 25 patients endoscopic dilation was followed by submucosal injection of long-acting steroid triamcinolone and the remaining 25 patients were taken as a control.Results: All patients have normal dietary intake including solid food at the time of discharge. All patients under study were regularly followed quarterly. Overall stricture recurrence can be reduced by intralesional triamcinolone injection providing stricture length <6 cm. Stricture >6 cm required a repeated procedure or other treatment modalities, In study group duration between endoscopic dilatation sessions fell significantly over a post dilatation period of 3 to 12 months.Conclusions: In addition to endoscopic dilatation, intralesional trimicinolone injection is safe, effective and significantly decrease stricture rate and decrease endoscopic dilatation sessions.
ABSTRACT
@#Objective To analyze the efficacy and safety of percutaneous balloon pulmonary valvuloplasty (PBPV) for pulmonary valve stenosis guided by ultrasound. Methods From March 2016 to July 2019, 32 patients with pulmonary valve stenosis were treated in our hospital. There were 19 males and 13 females with an average age of 1-12 (6.2±3.1) years and weight of 7-45 (22.7±9.2) kg. The clinical efficacy of PBPV guided by transthoracic echocardiography (TTE) was evaluated. Results The transvalvular pressure gradient (PG) of the patients before PBPV was 65.4±11.9 mm Hg. All patients successfully received PBPV under TTE guidance. The PG was 19.7±4.0 mm Hg immediately after operation, which was significantly decreased (P<0.001). All patients survived without any serious complications. The PG values at 3 months, 6 months and 12 months after operation were 18.4±4.0 mm Hg, 16.4±3.9 mm Hg, 15.2±3.3 mm Hg, respectively, which were significantly lower than that before the operation (P<0.001). Conclusion PBPV guided by echocardiography is safe and effective in the treatment of pulmonary valve stenosis with low complications rate.
ABSTRACT
Objective: To investigate the application effect of balloon dilatation and percutaneous nephrolithotomy (PCNL) combined with pneumatic and ultrasound lithotripsy on the clinical treatment of unilateral kidney stones. Methods: Ninety-four patients with unilateral kidney stones who accepted PCNL in the Department of Urology, Xinhua Hospital, Shanghai Jiao Tong University School of Medicine from June 2017 to July 2019, were retrospectively analyzed and divided into group A and group B. Among them, 68 patients (group A) were subjected to balloon dilatation combined with pneumatic and ultrasound lithotripsy, while 26 patients (group B) underwent fascia dilatation combined with holmium laser lithotripsy. The clinical effects of two kinds of lithotripsy on the treatment of unilateral kidney stones were compared. Results: The operation time was shorter in group A than that in group B [(107.82±10.87) min vs (115.41±10.68) min, P=0.003]. The increase rate of postoperative white blood cell (WBC) was lower in group A than that in group B (4.41% vs 23.08%, P=0.018). The fever ( ≥ 38.5 ℃ ) rate was lower in group A than that in group B (4.41% vs 23.08%, P=0.018). There were no significant differences in hemoglobin reduction, WBC count, hospital stay, stone-free rate, blood transfusion rate and perforation rate of collection system between the two groups (all P>0.05). Conclusion: Balloon dilatation combined with pneumatic and ultrasound lithotripsy in treatment of unilateral renal stones by PCNL can shorten the operation time, and reduce the increase rate of postoperative WBC and fever rate, which is worthy of being promoted in the clinical treatment of patients with unilateral kidney stones.
ABSTRACT
Background: Aortic valve stenosis (AVS) represents 3%–7% of all congenital heart diseases. Balloon aortic valvuloplasty (BAoV) has been established as an alternative to surgery for therapy of AVS in infants and children; and has proven to be an effective method for decreasing the gradient between the left ventricle and the aorta. The objective of the study was to evaluate the initial and medium-term results of BAoV in newborns, infants and children with severe AS, treated at the Alexandria University Children’s Hospital.Methods: Thirty-seven newborns, infants and children with severe AS treated by B AoV between 2009 and 2017 were studied. They were followed-up for at least 1year post- ballooning by clinical and echocardiographic evaluation.Results: The mean AoV annulus diameter by echo was 13.1±4.4 mm and by angiographic measurement was 12.8±4.3 mm. The mean Doppler gradient across AoV was 91.8±14.7 mmHg, compared to mean catheter gradient of 66.1±13.4 mmHg. The mean inflated balloon diameter was 12.1±4.1 mm. The mean balloon/AoV annulus ratio by angiogram was 0.94±0.03 (0.88–1). The mean pressure gradient across the AoV post-ballooning was 21.5±6.9 mmHg by Doppler and was 10.3±4.7 mmHg by catheter, both were significantly less than pre-ballooning values (p<0.001). The procedure was successful in all the cases. Only one case died. Post -ballooning aortic incompetence was moderate in 2 cases (5.4%) and severe in only one case (2.7%).Conclusions: Balloon aortic valvuloplasty is an effective and safe technique for relieving severe aortic valvular stenosis with acceptable morbidity and minimal mortality, particularly with the new catheter and balloon technology.
ABSTRACT
Shone complex is an extremely rare and severe congenital heart disease characterized by left -heart obstruction at multiple levels namely supravalvular mitral ring, parachute mitral valve, subaortic stenosis and coarctation of the aorta. We in the present case describe a patient of shone complex who underwent successful coarctoplasty with the help of BIB (balloon in balloon) dilatation catheter and covered CP (cheatham platinum) stent. The role of interventional cardiologist is to diagnose and choose the right approach for the specific patient, whether surgery, balloon or stent.
ABSTRACT
Balloon dilatation under bronchoscope is mainly used in the treatment of benign airway stenosis in children. It is a safe,simple and minimally invasive treatment. It also plays an important role in the removal of some special foreign bodies and the treatment for massive hemoptysis. Interventional therapy under bronchoscope is a comprehensive treatment technique,and balloon dilatation needs to be combined with other methods.
ABSTRACT
Objective To evaluate the curative effect and prognosis of endoscopic papillary large balloon dilatation ( EPLBD) in the treatment of choledocholithiasis. Methods A total of 153 patients with choledocholithiasis (>1. 0 cm in stone diameter) admitted and treated in Shanxi People's Hospital from August 2016 to November 2017 were randomly divided into two groups according to the random number table: the EPLBD group ( n=83) and the small endoscopic sphincterotomy plus large balloon dilatation ( ESLBD) group ( n=70) . The success rate of stone removal, the rate of lithotripsy, and the incidence of short-term and long-term complications were compared between the two groups. Results There were no statistical differences between the EPLBD group and the ESLBD group in total stone removal rate [ 95. 2％( 79/83) VS 97. 1％ ( 68/70) ,χ2=0. 388, P=0. 533] and one-time stone removal rate [ 92. 8％ ( 77/83) VS 90. 0％ ( 63/70) ,χ2=0. 375, P=0. 540] . The lithotripsy rate between the two groups had no statistical difference [ 25. 3％ ( 21/83 ) VS 35. 7％ ( 25/70 ) , χ2 = 1. 958, P= 0. 162 ] . There was no statistical difference in the incidence of recent complications between the two groups [ 43. 4％ ( 36/83 ) VS 40. 0％(28/70), χ2=0. 178, P=0. 673]. No postoperative perforation was found in either group. The follow-up time was 22. 7 ± 4. 3 months in the EPLBD group, and 20. 8 ± 6. 3 months in the ESLBD group. The cumulative recurrent rate of choledocholithiasis in the two groups were 2. 4％ ( 2/83) and 15. 7％ ( 11/70) , respectively, and the difference was significant ( P=0. 003) . Conclusion Simple EPLBD in the treatment of choledocholithiasis is equivalent to ESLBD in the success rate of stone removal, utilization rate of lithotripsy, and incidence of recent complications, but the long-term stone recurrence rate of EPLBD is lower than that of ESLBD. EPLBD is effective and safe on the treatment of choledocholithiasis.
ABSTRACT
Objective To evaluate the clinical curative effect of multiple interventional techniques with skilled manipulation in treating common bile duct stones. Methods The clinical data of 36 patients with common bile duct stones, who were treated with percutaneous transhepatic puncture of intrahepatic bile duct and multiple interventional techniques, were retrospectively analyzed. Before operation, according to CT or MRI findings the optimal puncture path was selected to perform cholangiography so as to reconfirm the position, number and size of the stones. Depending on the size of the stone, the corresponding sized lithotripsy basket and balloon were selected. The duodenal papilla was dilated by balloon, and the stone was pushed into the duodenum with a balloon. After complete removal of stones, the internal and external biliary drainage tubes were routinely implanted and remained there for two weeks. Results The operation was successfully accomplished in 35 patients, the success rate was 97.2％. Successful removal of stones with single procedure was accomplished in 32 patients, and in 3 patients the complete removal of stones was achieved by secondary procedure. No serious complications were observed during the operation. Early postoperative complications included hyperamylasemia (n=2), bile peritonitis (n=2), small amount of bloody bile (n=3) . No biliary perforation occurred. Conclusion In treating common bile duct stones, the combination use of multiple interventional techniques with skilled manipulation has high success rate, low risk and less complications, therefore, it is an effective therapeutic method
ABSTRACT
Objective To evaluate the safety and effectiveness of endovascular balloon dilatation in removing incarcerated tunnel cuffed catheter (TCC) . Methods The clinical data and the imaging materials of 4 hemodialysis patients with incarcerated TCC, who received endovascular balloon dilatation at Taizhou Hospital of Zhejiang Province, China, during the period from January 2017 to March 2018, were retrospectively analyzed. After the treatment, the patient's vital signs were monitored, and the procedure-related complications such as hemopneumothorax, subcutaneous hematoma, arrhythmia, etc. were documented. Results The mean age of the 4 patients was (73.3±6.4) years. The average indwelling time of TCC was 5.5 years (4-8 years) . Successful treatment of incarcerated TCC was achieved in all 4 patients. In one patient, both 5-mm and 6-mm balloons were used to simultaneously dilate the dual cavities of TCC.Temporary arrhythmia occurred in one patient during operation. No serious postoperative complications occurred. Conclusion For the remove of long-term indwelling incarcerated TCC, endovascular balloon dilatation is minimally-invasive, safe and effective, although more researches are needed to further confirm its safety and reliability.
ABSTRACT
Objective To explore the effect of mitral valve morphology on short-term and long-term outcomes in elderly patients with rheumatic mitral stenosis(MS)undergoing percutaneous balloon mitral valvuloplasty(PBMV).Methods In the prospective study,elderly patients with rheumatic mitral stenosis undergoing PBMV between February 1996 and June 2007 were followed up for 10 years.One hundred and twenty-four patients with full follow-up data were included in the study.According to echocardiography Wilkins score,83 cases of patients (Wilkins score ≤ 8)were selected as Wilkins score ≤ 8 group,and 41 cases were selected as Wilkins score＞ 8 group.The pressure gradient in mitral valve(MV△P),mitral valve area(MVA),left atrial diameter(LAD),left ventricular end-systolic diameter(LVESd),left ventricular end-diastolic diameter(LVEDd),pulmonary artery systolic blood pressure(sPAP),ejection fraction(EF)and mitral regurgitation were measured before and after the operation.Results In both Wilkins score ≤ 8 group and Wilkins score＞ 8 groups,MVA and EF were increased immediately after PBMV operation versus before PBMV operation,and MV△P,LAD,LVEDd,LVEDs and PAPs were decreased immediately after PBMV operation versus before PBMV operation(all P ＜0.05).Severe mitral regurgitation was not found in both two groups.The clinical effects of the Wilkins score≤8 group were stable after 10 years,which had no significant difference in the indexes compared with those in the Wilkins score≤ 8 group immediately after PBMV(P＞0.05).MVA and EF in the Wilkins score＞8 group were decreased,and MV△P,LAD,LVEDd,LVEDs and PAPS were increased after 10 years as compared with those immediately after PBMV(P＜0.05).The incidence of NYHA functional class Ⅲ or Ⅳ was lower in the Wilkins score ≤8 group than in the Wilkins score＞8 group(26.5％ or 22/83 vs.46.3％ or 19/41,x2 =4.879,P=0.027).And the incidence of mitral restenosis was lower in the ≤8 group than in the Wilkins score＞8 group(34.9％ or 29/83 vs.61.0％ or 25/41,x2 =7.567,P=0.006).There was no significant difference in the incidence of moderate or severe mitral regurgitation between the two groups(10.8％ or 9/83 vs.12.3％ or 5/41,x2=1.278,P=0.258).Conclusions The short-term and long-term outcomes are good in elderly individuals with rheumatic mitral stenosis undergoing PBMV operation,and the curative effect of PBMV operation is better in patients with Wilkins score ≤8 than in patients with Wilkins score ＞8.

Introduction: Endoscopic dilatation is the first therapeutic option to eliminate benign esophageal stenosis and improve the symptoms and the quality of life of those patients who suffer from it. Objective:To describe the results of endoscopic dilatation in patients with benign esophageal stenosis treated in the National Center for Endoscopic Surgery from January 2015 to December 2016. Material and Methods:A case series longitudinal observational study was conducted in 59 patients with benign esophageal stenosis. Dilatations were done with Savary-Gilliard bougie and balloons. Results:The mean age was 52,5 years, and the condition predominated in 37 male patients (62,7 percent). Post-surgical, peptic, and caustic were the most frequent etiologies with 25, 14, and 6 cases, respectively. Short stenosis predominated in 51 cases. Bougies were used in 48 patients for a total of 149 dilatations, corresponding to a mean of 3,1 dilatations/ patients. Correction of the stenosis was made in 1-3 sessions in 47 percent of patients; 11 cases were dilated with balloon, corresponding to a mean of 1- 3 dilatations/ patients. Four patients from the group that were dilated with Savary-Gilliard bougies showed refractoriness. A perforation, and two bleedings occurred. After the dilatations, dysphagia improved or disappeared in 93,2 percent of patients. Conclusions:Endoscopic therapy through dilatation of benign esophageal stenosis indicated to be a good alternative method in achieving corrections in a few dilatation sessions, with a low number of complications, and an improvement of the dysphagia(AU)
