ABSTRACT

Objective:To compare the efficacy of pneumovesicoscopic Cohen and Politano-Leadbetter procedures in the treatment of vesicoureteral junction obstruction (VUJO) in children.Methods:The data of 48 children with VUJO who underwent operations in the Department of Urology, Anhui Provincial Children′s Hospital from January 2017 to December 2021 were retrospectively analyzed.According to the operation time, the patients were divided into the pneumovesicoscopic Cohen group(group C) (28 cases) and pneumovesicoscopic Politano-Leadbetter group(group P) (20 cases). The operation time, postoperative urinary catheterization duration, hematuria duration, hospitalization time, and the improvement of hydronephrosis, ureteral dilatation, and renal function after surgery were compared between the 2 groups.The enumeration data were compared by the χ2 test or Fisher′ s exact probability method.The measurement data were compared by the t-test. Results:All the 48 children were successfully operated on by the same surgeon, without conversion to open surgery.Six cases in the group C had a megaureter and underwent ureter tailoring.Two cases in the group P had calyceal and ureteral calculi, which were all removed after operation.There was a statistically significant difference in the operation time between group C and group P[(136.5±35.4) min vs.(165.8±33.2) min, t=-3.154, P=0.002]. The patients were followed up for (10.3±2.6) months after operation.There were 8 cases and 6 cases of urinary tract infection in group C and group P within 2 months after the operation, respectively.They all improved after conservative anti-infection treatment, and the infection was well controlled after removal of the D-J tube.Besides, their intravenous pyelography 6 months after operation showed that the ureter was unobstructed.In group C, 6 months after the operation, the anterior and posterior diameters of the renal pelvis [(1.62±0.54) cm vs.(2.55±1.24) cm, t=-5.027, P=0.001] and the largest diameter of the ureter [(0.95±0.27) cm vs.(1.51±0.52) cm, t=-8.495, P<0.001] were significantly decreased, compared with those before operation.However, the renal cortex thickness was increased significantly [(1.47±0.25) cm vs.(0.86±0.46) cm, t=2.028, P=0.004], and the renal function (as indicated by the diuretic nephrogram) was notably improved [(46.27±2.16)% vs.(41.83±3.04)%, t=1.647, P=0.030]. In group P, 6 months after operation, the anterior and posterior diameters of the renal pelvis[(1.48±0.82) cm vs.(2.68±1.41) cm, t=-2.740, P=0.003] and the maximum diameter of the ureter [(1.05±0.46) cm vs.(1.36±0.27) cm, t=-1.635, P=0.040] were significantly smaller than those before operation.However, the renal cortical thickness was increased [(1.38±0.33) cm vs.(0.74±0.39) cm, t=9.073, P<0.001], and the renal function (as indicated by the diuretic nephrogram) was significantly improved [(45.18±3.35)% vs.(39.55±2.49)%, t=1.277, P=0.030]. Politano-Leadbetter surgery outperformed Cohen surgery in promoting the recovery of the anterior and posterior diameters of the renal pelvis [(1.48±0.82) cm vs.(1.62±0.54) cm, t=-1.748, P=0.030]. Conclusions:Pneumovesicoscopic Politano-Leadbetter operation can establish a longer submucosal tunnel without changing the ureteral shape and opening position, having good effects in treating VUJO combined with calyceal and ureteral calculi.Pneumovesicoscopic Politano-Leadbetter operation can also better improve postoperative recovery from hydronephrosis than Cohen operation.However, the pneumovesicoscopic Politano-Leadbetter operation is more difficult and requires longer time.The surgeon should choose a reasonable operation based on his/her own experience.

ABSTRACT

With continuous improvements in surgical techniques, medical engineering and material science, root replacement with composite valve graft (CVG) or Bentall procedure has become the standard procedure for aortic root lesions. As an alternative to the Bentall procedure, valve-sparing aortic root replacement (VSRR) avoids the complications associated with lifelong anticoagulation and mechanical valves; reduces the incidence of thromboembolic and bleeding events; and its favorable haemodynamics and potentially lower risk of endocarditis ensure durable postoperative aortic valve function and a much better quality of patient survival. This article reviews the indications for root replacement with preservation of the aortic valve, the key points of the standardized technique and its long-term results in different patients.

ABSTRACT

RESUMO Objetivo Caracterizar os limiares auditivos nas frequências de 500, 1000, 2000 e 4000 Hz em crianças submetidas ao reimplante com follow-up de no mínimo 10 anos. Método Revisão retrospectiva de prontuários de crianças submetidas a cirurgia de reimplante há pelo menos 10 anos. Foram avaliados os limiares auditivos obtidos na audiometria tonal liminar em campo livre com o implante coclear nas frequências de 500, 1000, 2000 e 4000 Hz em quatro momentos distintos: 1 (antes da falha), 2 (ativação), 3 (cinco anos após o reimplante) e 4 (dez anos após o reimplante, independentemente do tempo de uso do uso do 2o IC) em pacientes com follow-up de no mínimo 10 anos. Resultados Avaliando-se pacientes submetidos ao reimplante, observou-se que os limiares de 500, 1000, 2000, 4000 Hz apresentaram-se a longo prazo semelhante àqueles obtidos nos pacientes implantados somente uma única vez, não apresentando prejuízo assim na detecção dos sons. Conclusão O reimplante não teve efeito de longo prazo sobre os limiares auditivos obtidos em crianças que se submeteram a esta cirurgia por falha do componente interno.


ABSTRACT Purpose To characterize hearing thresholds at frequencies of 500, 1000, 2000 and 4000 Hz in children undergoing reimplantation with a follow-up of at least 10 years. Methods Retrospective review of medical records of children who underwent reimplantation surgery for at least 10 years. The auditory thresholds obtained in free-field pure tone audiometry with the cochlear implant were evaluated at frequencies of 500, 1000, 2000 and 4000 Hz at four different times: 1 (before failure), 2 (activation), 3 (five years after reimplantation) and 4 (ten years after reimplantation, regardless of the time of use of the 2nd CI) in patients with a follow-up of at least 10 years. Results Evaluating patients who underwent reimplantation, it was observed that the thresholds of 500, 1000, 2000, 4000 Hz were similar in the long term to those obtained in patients who were implanted only once, thus not presenting damage in the detection of sounds. Conclusion Reimplantation had no long-term effect on the hearing thresholds obtained in children who underwent this surgery due to internal component failure.

ABSTRACT

Background:Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital anomaly leading to progressive left ventricular dysfunction and mitral regurgitation. We conducted this study to investigate various measures to optimize the outcomes of surgical correction for ALCAPA. Materials And Methods: This was a single?centre, retrospective, observational study including consecutive patients operated for ALCAPA. The main outcomes evaluated were in?hospital mortality, duration of mechanical ventilation, and duration of intensive care unit (ICU) stay. Independent sample t? test and Fisher’s exact test were used for the analysis of continuous and categorical variables respectively. Results: 31 patients underwent surgical correction for ALCAPA during the study duration. The median age was 7.3 months with a range of 21 days to 25 months. All patients underwent coronary re?implantation with the coronary button transfer technique. There was no in?hospital mortality, the mean duration of mechanical ventilation and ICU stay was 117.6 hours and 10.7 days respectively. Age at admission, development of acute kidney injury after surgery, lactate levels at 12? and 24?hours post?surgery, and heart rate at ICU admission and 12?hours post?surgery were significantly associated with mechanical ventilation duration longer than 48 hours. Use of a combination of levosimendan and milrinone and elective intermittent nasal continuous positive airway pressure ventilation after extubation in all patients with severe left ventricular dysfunction were helpful in preventing low cardiac output and need for reintubation post?surgery respectively. Conclusion: Surgical correction for ALCAPA by coronary re?implantation has an excellent short?term outcome. Optimal postoperative management is of utmost importance for achieving the best results.

ABSTRACT

The present case aims to describe the management of a complicated crown en masse fracture in a maxillary central incisor due to trauma by intentional replantation as the chosen treatment modality. Intentional replantation aiming towards successful endodontic therapy comprises intentional therapeutic extraction of the tooth and an endodontic procedure in a controlled environment followed by replantation. A 24-year-old female patient presented to the department with a chief complaint of broken upper front teeth following trauma. The teeth were tender on percussion. The periapical radiographic examination revealed a complicated fracture involving the pulp without significant periapical changes. A diagnosis of Ellis Class III was established and intentional reimplantation was planned with the patients consent. Following an atraumatic extraction, conventional root canal treatment was completed. Subsequently, a fibre-post was used to reinforce the tooth structure. The tooth was placed back into the socket and splinted. One year of follow up examination revealed absence of pain and periapical healing. The treatment yielded a clinical, aesthetic and functionally satisfactory result, establishing intentional replantation to be a feasible treatment option in complicated crown en masse fracture of the tooth.

ABSTRACT

The fistulas, following gynecologic, surgeries are not uncommon. Hysterectomy is one of the most common causes of lower urinary tract fistula in pelvic surgery. Higher incidences are associated with laparoscopic hysterectomy as compared to vaginal or abdominal hysterectomy. Early identification and management of ureterovaginal fistula (UVF) are of utmost importance. The laparoscopic approach in the management of UVF is preferred over open surgery as it reduces pain, hospital stay, and morbidity. However, the laparoscopic approach needs higher surgical dexterity, sound knowledge of pelvic anatomy, and has a higher learning curve. One such approach is discussed here.

ABSTRACT

@#Distal ureteral injury is a rare complication of laparoscopic radical prostatectomy (LRP). The authorsreport such a case which was repaired successfully with an exclusively laparoscopic approach. Theyalso describe the advantages of the flank position when performing this minimally invasive approach.@*THE CASE@# 61-year-old Filipino male, with a PSA of 10 ng/cc, diagnosed with localized prostatecancer undergoes LRP, utilizing a posterior approach to the seminal vesicles. Intraoperatively, alarge intravesical median lobe was noted which was dissected meticulously after the division of thebladder neck. The excision of the 60gm prostate was completed in the conventional manner followedby a urethrovesical anastomosis. Blood loss was minimal with no apparent intraoperative events.Histopathology confirmed prostate cancer, Gleason score (4+3) with negative margins. Postoperatively,he had progressively high pelvic drain output and noticeably a relatively low urethral catheter output.CT urogram done on POD 8 showed a distal left ureteral disruption with intraabdominal extravasation.The authors performed a laparoscopic left ureteroneocystostomy on POD 9. The patient did wellafter the repair. After removing the indwelling catheter on postoperative day 14, he was dischargedin a good clinical condition. The ureteral stent was removed one month after the reimplantation.Follow-up CT urogram showed unobstructed flow through the reimplanted left ureter. Follow-upPSA at this time was 0.01ng/cc.@*CONCLUSION@#Ureteral injury following LRP is a devastating complication which may go undiagnosedintraoperatively. Prompt recognition, followed by a timely minimally invasive repair through alaparoscopic approach is needed to correct this problem.

ABSTRACT

Objective:To investigate the long-term efficacy and complications of augmentation uretero-enterocystoplasty (AUEC).Methods:The clinical data of 262 patients with lower urinary tract dysfunction who underwent AUEC at our center from January 2003 to June 2022 were analyzed retrospectively. There were 193 males and 69 females, the median age was 24 (4, 67) years, the median disease duration was 12.0 (0.2, 56.0) years and the preoperative creatinine was 91.5 (68.1, 140.0) μmol/L. 320 ureters had high-grade UUTD, 216 ureters had VUR, 14 of which had low-pressure reflux.The number of low-grade VUR ureter was 22 (10.2%) and the number of high-grade VUR ureter was 194 (89.8%). Video-urodynamics showed that the maximum bladder capacity was 102 (47, 209) ml, the maximum detrusor pressure was 33.0 (15.5, 50.5) cmH 2O, and the bladder compliance was 6.4 (3.0, 12.3) ml/cmH 2O. All patients underwent AUEC. The surgical method is to cut a segment of sigmoid colon, open the sigmoid colon along the mesenteric margin, fold and suture it into " U" or " S" shaped intestinal mesh according to the principle of " detubulization" . At the same time, perform ureteroplasty and replanting, and then anastomosis the intestinal mesh with the opened bladder flap to form an expanded new bladder. Follow-up was performed via outpatient clinic or telephone. The creatinine, maximum bladder capacity, maximum detrusor pressure, bladder compliance, ureteral reflux and upper urinary tract dilatation were compared preoperatively and postoperatively. The postoperative complications were also evaluated. Results:The median follow-up time was 57.4 (4, 151) months after surgery. At 1-3 months after surgery, the maximum bladder capacity and bladder compliance increased to 303.9% and 189.9% of the preoperative level, and the maximum detrusor pressure decreased to 63.6% of the preoperative level. At 6-10 years after surgery, the maximum bladder capacity and bladder compliance increased to 490.2% and 627.9% and the maximum detrusor pressure decreased to 25.8% of the preoperative level. The UUTD of the patients was significantly reduced after surgery. The number of the high grade UUTD decreased to 116 (116/398, 29.2%) at 1-3 months and 51 (51/274, 18.6%) at 4-6 months. At 6-10 years, the number of the high-grade UUTD decreased to 4 (4/76, 5.3%) ( P<0.001), which was significantly lower than that before operation. The VUR was significantly relieved after operation, and 393 ureters had no VUR at 1-3 months, accounting for 97.8% (393/402) of the total ureters. Sustained remission of VUR was observed during follow-up. 73 ureters had no VUR at 6-10 years, accounting for 96.1% (73/76) of total ureters ( P<0.001). Patients' creatinine decreased to 79.0 (65.0-128.2) μmol/L at 1-3 months postoperatively, with a downward trend but no statistical difference, and creatinine levels were not significantly elevated at any postoperative time point compared with preoperative levels ( P>0.05). Postoperative complications included metabolic acidosis in 26 cases (9.9%), vesicoureteral anastomosis stenosis in 15 cases (5.7%), recurrent urinary tract infection in 16 cases (6.1%), and urinary calculi in 20 cases (7.6%), and intestinal obstruction requiring laparotomy in 8 cases (3.1%), all of them could be improved after treatments. Conclusions:AUEC is a safe and effective method for treating high-grade VUR or VUR with impaired anti-reflux mechanism, high-grade UUTD or UUTD with ureteral or vesicoureteral junction obstruction, and all of the complications can be improved after treatment. This technique can increase the bladder capacity and compliance, reconstruct the anti-reflux mechanism, and release upper urinary tract obstruction. It may play an important role in stabilizing and protecting the residual renal function from further deterioration.

ABSTRACT

Anomalous origin of the right coronary artery from the pulmonary artery (ARCAPA) is a rare congenital defect, and few cases have been reported in the pediatric age group. Unlike the anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA), patients with ARCAPA are usually asymptomatic and often diagnosed incidentally. Here, we present a surgical case of a 2-month-old male who was suspected of having ARCAPA in the neonatal period. The patient was suspected of having ARCAPA due to the detection of a heart murmur and the results from an echocardiogram taken the 4th day after birth. Coronary angiography on the 37th day after birth showed the contrast flow to the pulmonary artery through the right coronary artery from the left coronary artery; thus, we diagnosed ARCAPA. Surgical intervention should be performed before the appearance of myocardial ischemia due to decreasing pulmonary artery pressure, so we performed reimplantation of the right coronary artery to the ascending aorta and patch plasty of the pulmonary artery at 2 months after birth. The patient was discharged from the hospital on the 16th day after the operation, and a 6-month postoperative coronary angiography revealed good right coronary flow and the disappearance of collaterals.

ABSTRACT

Resumen Introducción: El origen anómalo de una de las ramas de la arteria pulmonar procedente de la aorta ascendente es poco frecuente. Objetivo: Identificar las características clínicas y quirúrgicas de los pacientes sometidos a reimplante de la rama afectada. Método: Se realizó un estudio observacional, transversal, descriptivo, retrospectivo y retrolectivo, en el que se incluyeron los pacientes diagnosticados de origen anómalo de alguna de las ramas de la arteria pulmonar y que fueron tratados mediante cirugía correctiva en el Instituto Nacional de Cardiología Ignacio Chávez, en el periodo del 1 de enero de 2003 al 31 de enero de 2019. De los expedientes se extrajeron las características demográficas, los antecedentes quirúrgicos, los diagnósticos, los reportes ecocardiográficos y tomográficos, la técnica quirúrgica y el estado posquirúrgico. Resultados: Se encontraron nueve pacientes sometidos a cirugía de corrección, con un promedio de edad de 2 ± 2 años, un peso de 11.4 ± 1.5 kg y una talla de 82 ± 15 cm. El 67% fueron de sexo masculino. La rama afectada con más frecuencia fue la derecha; el 68% se originaban directamente de la aorta y el 42% de un conducto arterioso persistente. La corrección con circulación extracorpórea tuvo un tiempo promedio de pinzamiento aórtico de 35 minutos y de soporte circulatorio de 45 minutos. Se utilizó el implante directo o con material sintético. Las complicaciones fueron falla ventricular, sangrado, arritmias y neumonía nosocomial. La mortalidad fue del 11%. Conclusiones: El tratamiento quirúrgico para el reimplante de la rama anómala de la arteria pulmonar es el procedimiento de elección, y con cuidados quirúrgicos y posteriores tiene un buen pronóstico a mediano y largo plazo.


Abstract Introduction: The anomalous origin of one of the branches of the pulmonary artery from the ascending aorta is rare. Objective: To identify the clinical and surgical characteristics of the patients undergoing reimplantation of the affected branch. Method: An observational, cross-sectional, descriptive, retrospective and retrolective study was performed; patients diagnosed with anomalous origin of one of the branches of the pulmonary artery and treated by corrective surgery at the Instituto Nacional de Cardiología Ignacio Chavez, in the period from January 1, 2003 to January 31, 2019, were included. It was extracted from the files: demographic characteristics, surgical antecedents, diagnoses, echocardiographic and tomographic reports, surgical technique and post-surgical status. Results: Nine patients underwent correction surgery, with an average age of 2 ± 2 years, 11.4 ± 1.5 kg and height 82 ± 15 cm; 67% were male. The most frequent affected branch was the right, 68% originated directly from the aorta and 42% from a patent ductus arteriosus. The correction with extracorporeal circulation had an average aortic cross-clamp of 35 minutes and circulatory support of 45 minutes, the direct or synthetic implant was used. The complications were ventricular failure, bleeding, arrhythmias and nosocomial pneumonia. Mortality was 11%. Conclusions: Surgical treatment for reimplantation of the anomalous branch of the pulmonary artery is the procedure of choice, which with surgical and subsequent care has a good prognosis in the medium and long term.

ABSTRACT

Anomalous aortic origin of a coronary artery is a rare congenital anomaly that can cause myocardial ischemia and ventricular arrhythmia. This disease initially manifests as cardiac arrest in half of patients. The indications and surgical strategy remain unclear, especially in patients who are asymptomatic and have poor ischemic findings. We report a surgical strategy to treat anomalous aortic origin of the right coronary artery. A 47-year-old man with a chief complaint of chest tightness was diagnosed with anomalous aortic origin of the right coronary artery, which branches from the left sinus of Valsalva and runs an inter-arterial course. Although no objective myocardial ischemia was identified with blood tests, electrocardiography, or cardiac catheterization, we suspected that the cause of the thoracic symptoms was sharp branching of the right coronary artery, which was compressed between the ascending aorta and the pulmonary artery. To reduce the risk of sudden death in the future, we performed reimplantation of the right coronary artery. Good imaging results were obtained, and the patient is currently undergoing outpatient follow up and has not experienced recurrence of chest symptoms. We conclude that our surgical strategy to treat anomalous aortic origin of a coronary artery may be useful in the clinic.

ABSTRACT

Objective:To evaluate the therapeutic characteristics of laparoscopic repair in children with ure-terovesical junction malformation through internal or external bladder.Methods:From February 2018 to August 2019, 29 cases of hydronephrosis combined with ureter expansion treated in the First Affiliated Hospital of Zhengzhou University, with 17 boys and 12 girls confirmed through the preoperative examinations.Inspection results revealed 15 cases of ureteropelvic junction obstruction, 12 cases of vesicoureteral reflux, and 2 cases of single ectopic ureter.Totally, 21 cases were treated by pneumovesical laparoscopic Cohen means, including 17 unilateral cases and 4 bilateral cases, 5 cases of ureterocele, and 8 cases of ureteral clipping.A total of 8 cases were treated by laparoscopic Lich -Gregoir surgical treatment, including 7 unilateral cases and 1 bilateral case.Meanwhile, 4 cases of ureteral clipping were performed among them.There was 1 case of duplex kidney with the ectopic upper ureter outside iliac blood vessels, 1 case of bilateral cryptorchidism and 1 case of unilateral cryptorchidism.Ureteral stents were implanted for those with ureteral tailoring.The catheters were removed 7 days after operation, and the indwelling ureteral stents were removed by cystoscope under general anesthesia after about 6 weeks.Results:All the cases with hydronephrosis and ureteral dilatation were completed in laparoscopic surgery, without open surgery or blood transfusion, 21 cases were treated by pneumovesical laparoscopic Cohen means, with the average time being 1.8 hours in unilateral side and 2.8 hours in bilateral sides.At the same time, 8 cases were treated by laparoscopic Lich-Gregoir means, with the unilateral average time being 1.7 hours and bilateral time being 3.0 hours.All cases were followed up at an average month of 9 (4-20 months), and all children underwent voiding cystourethrography 4 months after the operations.The voiding cystourethrogram(VCUG) of all the cases was confirmed successfully, with only 1 case of vesicoureteral reflux in level Ⅲ, and their hydronephrosis were relieved.There was no vesicoureteral reflux in the others.The short-term urinary retention occurred in 1 patient with bilateral ureteral reimplantation in Lich-Gregoir group, and the symptom disappeared after 1 week of indwelling catheterization.Among them, 1 patient in Cohen group had hematuria that disappeared gradually for 4 days after surgery.There were no significant differences in operation time and postoperative recovery between the two groups.The length of hospital stay in laparoscopic Lich -Gregoir group was slightly longer than that in pneumovesical laparoscopic Cohen group.Conclusions:As for children with ureterovesical junction malformation, laparoscopic Lich-Gregoir surgery is suitable for the ectopia of ureter opening, overexpansion of ureter, and other abdominal malformation complicated and expansive ureter without tortuosity.Pneumovesical laparoscopic Cohen surgery is suitable for hydronephrosis and ureteral expansion with ureterocele, especially with the symptom of dysuria, and ureteral tortuosity obviously.The two ways are safe and reliable, and the advantages and disadvantages should be weighed before being chosen.

ABSTRACT

Abstract Objective: To compare the early and long-term results of patients in whom was performed modified closed coronary transfer with the results of patients in whom was performed trap-door transfer techniques by utilizing propensity-matching analysis to provide optimal identical patient matching for the groups. Methods: From August 2015 to December 2017, 127 consecutive patients underwent arterial switch operation due to simple and complex transposition of the great arteries, with or without additional arch and complex coronary pattern, by a single surgical team included into the study. Of these, in 70 patients it was performed modified closed coronary transfer technique and in 57 patients it was performed trap-door style coronary transfer technique. The patients were divided into two groups in terms of coronary transfer method. In the final model, after propensity matching, 47 patients from each group having similar propensity score were included into the study. Results: There was no significant difference between the groups regarding patient characteristics. Cross-clamp time and operation time were significantly lower in the modified technique group compared with the other group (P=0.03 and P=0.05, respectively). When compared the early and late postoperative outcomes, there was no significant difference between the groups. Postoperative echocardiographic findings were mostly similar between the groups. Conclusion: The patients in whom was performed our modified technique demonstrate overall good outcomes and the current technique ensures shorter arterial cross-clamp and operation times. It may be an alternative method to the trap-door technique for the coronary transfer during the arterial switch operation.

ABSTRACT

El reimplante es la obra maestra del cirujano de mano, donde incluye la técnica microquirúrgica para la anastomosis de arteria, vena y reparación del nervio, la osteosíntesis de los huesos y el manejo de tejidos blandos como los tendones y la piel Indicaciones absolutas, amputación del pulgar, el pulgar es quizás el elemento más importante de la mano, dado que le da funcionalidad a la extremidad, sin importar la movilidad final ni la sensibilidad debe reimplantarse el pulgar. No se debe intentar el reimplante en lesiones aplastantes de los dedos, amputación en más de un nivel, presencia de lesiones que amenacen la vida del paciente, enfermedades graves del paciente, isquemia prolongada, amputaciones en paciente con alteraciones psiquiátricas. Clasificación según Tamai es la mas utilizada. Se explica además como se debe transportar la parte amputada. La técnica microquirúrgica es lo mas importante para el desenlace. La rehabilitación física y posibles complicaciones.


Reimplantation is the masterpiece of the hand surgeon, which includes the microsurgical technique for artery anastomosis, vein and nerve repair, osteosynthesis of the bones and the management of soft tissues such as tendons and skin. Absolute indications, Amputation of the thumb: the thumb is perhaps the most important element of the hand because it gives functionality to the limb, regardless of the final mobility or sensitivity it should be reimplanted. Reimplantation should not be attempted in crushing lesions of the fingers. Crush injury of the fingers may have multilevel amputation and microcirculation injury that may not be susceptible of repair. Amputation at more than one level, the presence of life-threatening injuries, serious illnesses of the patient, prolonged ischemia, amputations in a patient with psychiatric disorders. Tamai Classification is the most used. We explain the correct way to transport the amputated part. The microsurgical technique is the most important in order to avoid complications. We also explain the physical therapy and complications.

ABSTRACT

In patients who need endodontic re-treatment, and where the prognosis for surgical or non-surgical re-treatment is poor or treatment may be risky, one alternative is to opt for extraction of the affected tooth and replacement by an implant. However treatment by intentional reimplantation (IR) is also a possibility. The object of the present study was to present a case of a patient aged 71 years who needed endodontic re-treatment, where IR treatment was selected. The patient reported spontaneous pain which disappeared completely with the use of analgesics. This tooth had previously been treated endodontically around 1 year earlier, and no pain was reported in the first two months after treatment.Nonetheless, about 3 months before the present consultation, intensity of the symptoms had increased with a sensation of pressure in the apical-coronal direction. Cone-beam computerised tomography (CBCT) showed a periapical lesion in tooth 3.7. Based on the clinical and imaging examinations, acute apical periodontitis was diagnosed in tooth 3.7.The tooth was treated by IR. It was carefully extracted and inspected for cracks or perforations. It was treated under the microscope with root resection, and then retrograde obturation was carried out with bioceramic material. The tooth was then repositioned in its alveolus. It was immobilised for 15 days, after which the patient could return gradually to normal masticatory function. In the 6 months check-up the patient presented no pain or sensitivity to percussion. No root resorption or periapical radiolucency was observed in the periapical X-ray. We conclude that IR is an alternative to extraction followed or not by prosthetic treatment, for patients who need endodontic re-treatment. The treatment presents good levels of success, and of acceptance by the patient.


En pacientes que necesitan de retratamiento endodóntico y el retratamiento quirúrgico o no quirúrgico tiene un pronóstico desfavorable o puede ser riesgoso, se puede optar por la extracción del diente afectado y su reemplazo por implante o se puede elegir el tratamiento mediante la técnica de reimplante intencional (RI). El objetivo del presente estudio fue presentar un caso de paciente de 71 años con necesidad de retratamiento endodóntico, donde se optó por la realización del RI. Paciente relatava dolor espontáneo que desaparecia completamente con el uso de analgésicos. Este diente ya había sido tratado endodónticamente hace alrededor de 1 año, y el paciente noreportó dolor en los primeros dos meses después del tratamiento.No obstante, hace aproximadamente 3 meses la intensidad de los síntomas aumentó, junto con la sensación de presión en el sentido ápice-corona. La tomografía computarizada cone-beam (TCCB) mostró lesión periapical en el diente 3.7. Basado en el examen clínico e imagenológico se diagnosticó periodontitis apical aguda en el diente 3.7.Para el tratamiento se realizó la técnica de RI, siendo extraído el diente cuidadosamente, e inspeccionado a fin de localizar fisuras o perforaciones. El diente fue tratado bajo microscopio y se realizó la resección de la raíz. Se realizó la obturación retrógrada con material biocerámico. Enseguida el diente fue reposicionado en su alveolo, la inmovilización fue realizada durante 15 días y la paciente logró retornar gradualmente a su función masticatoria. En el seguimiento de 6 meses la paciente no presentó dolor o sensibilidad a la percusión. En la radiografía periapical no se observó resorción radicular o radiolucencia periapical. Concluimos que el RI en pacientes que necesitan retratamiento endodóntico es una alternativa a la realización de la exodoncia seguida o no, de tratamiento protético, donde existe una buena aceptación por parte del paciente y éxito en el tratamiento.

ABSTRACT

ObjectiveTo evaluate the appropriate indications, key points of surgical techniques, and early to midterm outcomes of valve-sparing aortic root reimplantation in patients with Marfan syndrome. MethodsThe clinical data of 52 patients with Marfan syndrome who underwent valve-sparing aortic root reimplantation in our department from June 2006 to July 2017 were retrospectively analyzed. Preoperative patient characteristics, surgical techniques, and follow-up outcomes were summarized. ResultsThe patients had a mean age of (36.6±14.5) years, with 35 males and 17 females. Severe aortic valve insufficiency (AI) was found in 37 cases (71.2%) preoperatively. Echocardiography indicated that the average diameter of aortic annulus, aortic sinus, and sinotubular junction of this cohort were 22-30 mm, 40-56 mm, and 34-51 mm, respectively. Pure valve-sparing aortic root reimplantation was performed in 40 patients presenting aortic root aneurysm, with a cross-clamp time of 61-108 min and a mean of (81.3±11.6) min, and with a cardiopulmonary bypass time of 88-129 min and a mean of (97.3±10.8) min. The other 12 patients with Stanford type A aortic dissection underwent concomitant total arch replacement and elephant trunk implantation in the descending aorta, with a cross-clamp time of 93- 126 min and a mean of (107.4±11.2) min, and with a cardiopulmonary bypass time of 127-180 min and a mean of (143.5±17.1) min. Vascular prostheses with a diameter of ≤30 mm were adopted in all patients. Aortic root bleeding was drained to the right atriums in 9 patients. Transesophageal echocardiography was performed in 42 cases before extracorporeal circulation removal, with 16 cases presenting no AI, 18 presenting trace AI, and 8 presenting mild AI. There was one in-hospital death (1.9%) and no secondary thoracotomy for bleeding or other major complications. The mean follow-up was (3.2±2.1) years, with 43 cases completed the follow-up and no death during follow-up. Echocardiography in the latest follow-up indicated that 6 cases presented no AI, 24 presented trace AI, 12 presented mild AI, and only one case presented moderate AI, with 97.7% (42/43) patients free from moderate AI. No case underwent aortic valve replacement for severe AI. There were 39 (90.7%) patients in New York Heart Association classIand 4 (9.3%) patients in classII . ConclusionApplication of valve-sparing aortic root reimplantation using vascular prostheses with appropriate diameter is safe and effective for suitable patients with Marfan syndrome, and can obtain satisfactory outcomes.

ABSTRACT

Objective To explore the feasibility and effectiveness of external ureteral clipping and insertion of double J tube in laparoscopic ureterobladder reimplantation. Methods The clinical data of 21 patients with lower ureteral stricture undergoing laparoscopic ureterobladder reimplantation from Mar. 2014 to Mar. 2016 were retrospectively analyzed. Twelve patients receiving conventional laparoscopic ureterobladder reimplantation were assigned to control group, and 9 patients receiving laparoscopy-assisted external ureterobladder reimplantation were assigned to improvement group. The ureter of the patients in the improvement group was separated under laparoscopy, the narrow ureter was severed, and the proximal ureter was taken out from the 12-mm Trocar. Then, the broken end of ureter was clipped under euthyphoria, and the double J tubes were inserted and fixed on the ureteral mucosa with 4-0 absorbable sutures and then sent back to the pelvis. The bladder was mobilized under laparoscopy, and the bladder and ureter were anastomosed. Results The surgery was successfully completed in all the 21 patients without transferring to open surgery or urine leakage after operation. The operation time was significantly shorter in the improvement group versus the control group ([77±17] min vs [104±20] min, P<0.05). All patients were followed up for at least 6 months after operation. Both ultrasonography and intravenous pyelography showed no ureteral anastomotic stricture. The hydronephrosis was alleviated to some extent. Cystography showed that 2 patients had reflux, with 1 case in each group. Conclusion In laparoscopic ureteral reimplantation, external ureteral clipping and insertion of double J tube are minimally invasive, and can shorten operation time and make the surgery less complex.

ABSTRACT

Objective@#To evaluate the clinical efficacy of robot-assisted laparoscopic ureteral reimplantation (RAUR) for primary obstructive megaureter (POM) in children.@*Methods@#Twenty-one patients who underwent RAUR for POM in Bayi Children’s Hospital between 2017 April and 2018 April were retrospectively analyzed. The study population consisted of 15 boys and 6 girls aged between 2 months and 11 years. Ten patients had left POMs, 9 had right POMs and two had bilateral POMs. All patients were preoperatively diagnosed with a POM based on urinary system ultrasonography, magnetic resonance urography, and diuretic renal dynamic imaging. Our main technique key steps include: Under general anesthesia, the patients were placed in a Trendelenburg position approximately 40 degrees from the horizon. An 8.5-mm camera port was placed at the level of the umbilicus. Followed by two 5-mm robotic Trocars placed under direct vision 6 cm to the camera port separately, a 5-mm assistant port was placed on the right upper abdominal quadrants which was located 3 cm from the camera and robotic port. The ureter was identified at the pelvic brim. The peritoneum covering the ureter was incised and the ureter was mobilized to the level of the vesico-ureteric junction. The bladder was filled with 60 ml saline and a 5 cm length and 1.5 cm wide submucosal detrusor tunnel was created. The ureter was transected at the bladder mucosa and the narrowed ureteral segment was discarded. The ureteroneocystostomy was performed using 6-0 absorbable suture. Dissecting the perivesical fascia appropriately and using down-top suturing approach, use of an apical stay stitch, and incorporation of the ureteral adventitia during detrusorraphy. Postoperative complications were analysed using the Clavien-Dindo classification. Success was defined as symptomatic relief, decreased hydronephrosis on ultrasound and no evidence of vesicoureteral reflux on voiding cystourethrography.@*Results@#All surgeries were successfully completed without conversion and no intra-operative complication was encountered. The mean operative time was 117.6±18.1(89-165)min, the mean estimated blood loss was 11.9±4.3(5-25)ml, the abdominal drainage tubes were removed after a mean of 4.9±1.1(3-8)days, and the mean postoperative hospital stay was 6.3±1.3(4-10) days. Postoperative complications (Clavien Ⅰ-Ⅱ) occurred in 9.5% (two patients had recurrent urinary tract infections postoperatively) children, no grade Ⅲ-Ⅳ complication was observed. The pre-operative symptoms in all patients disappeared. One patient had grade Ⅱ VUR on VCUG, who were followed conservatively. Ultrasound at postoperative follow-up showed that the hydronephrosis was disappeared in 20 ureters and significantly decreased in 3 ureters. The success rate was 95.7% at a mean follow-up of 16.3±4.0(10-23)months.@*Conclusion@#RAUR is a safe and feasible option for the treatment of POM in children with higher success rate and lower complication rate.

ABSTRACT

Background: Tuberculosis can affect any organ system of the body, including the genitourinary tract. Genitourinary TB is the most common form of extra pulmonary TB accounting for 27% (14- 41%) worldwide. Aim and objectives: To study distribution of GU TB in relation to age, sex, anatomical site, signs and symptoms and to study various diagnostic modalities, treatment and role of surgery in GU TB. Materials and methods: This study was a cross sectional study done at department of Urology, King George hospital, Visakhapatnam. The study was done over a period of 30 months, which was from September 2014 to February 2017. All the patients reporting to the hospital with proven genitourinary tuberculosis or diagnosed after coming to the hospital were included in the study. Total number of cases was 35. 10 were males and 25 were females. History, physical examination, laboratory and radiological investigations were done on the patients and the primary focus of the disease and organs involved are determined. All the patients received treatment as indicated. Results: Most of the patients (33 out of 35) belonged to low socio-economic status and came from rural settings. Of them 10(28.57%) were males and 25(71.43%) were females. The mean age of patients was 36 years (range 16-60years). 2 patients were <20 years, 11 patients were between 21-30 years, 11 patients were between 31-40 years, 8 patients were between 41-50 years and 3 were above 50 years. In this study, kidney was involved in 19 cases and was the most common organ involved, followed by bladder (14 cases) and ureter(10 cases). Irritative voiding symptoms were the most common symptom seen in 23 cases. Flank pain was noted in 20 cases, sterile pyuria in 22 cases and hematuria in 7 cases. Six(17.14%) out of thirty five patients had renal failure at the time of presentation and diagnosis. Nephrectomy was done in 12 cases. Nephrectomy with augmentation Immadi Chandrasekhar, Pasalapudi Anurag Jose. Clinical study and management of genitourinary tuberculosis. IAIM, 2019; 6(1): 48-57. Page 49 cystoplasty and ureteric reimplantation was done in another 6 cases. Ileal conduit was done in 6 cases. Ureteric reimplantation with psoas hitch was done in 3 cases. Conclusion: Genitourinary tuberculosis is often silent and has nonspecific clinical features. Irritative voiding symptoms are the common presentation. Kidney is the most commonly affected organ in GU TB. GU TB is a disease of young adults, with majority affected in the 3rd and 4th decades. CT scan is replacing IVU as an imaging modality of choice in GU TB. Diagnosis of GU TB can be baffling, compelling a high index of suspicion owing to paucibacillary load in the biological specimens and the difficulty to isolate or grow TB bacilli. Hence a strong clinical suspicion is necessary for correct diagnosis. Anti-tubercular therapy is the mainstay of treatment. Genitourinary tuberculosis results in sequel which may require major organ removing and reconstructive surgeries
