Abstract
BACKGROUND Ureteral reimplantation remains the primary surgical method used for patients with vesicoureteral reflux (VUR). Cystoscopy is commonly performed first to visualize anatomy and rule out possible abnormalities. Urine cultures may also be obtained. The objective of this study is to evaluate the prudency of preoperative urine cultures and cystoscopies in pediatric patients undergoing ureteral reimplantation. METHODS Pediatric urologists were surveyed regarding collecting urine cultures in asymptomatic patients and cystoscopies before reimplantation. A retrospective review was also conducted of patients who underwent ureteral reimplantation for VUR between March 2018 and April 2021 at Cook Children's Medical Center. RESULTS When physicians were asked the frequency they obtain urine cultures before reimplantation on asymptomatic patients, 36% said "never" and 38% said "always." Regarding cystoscopy, 53% said "never" and 32% said "always." Inclusion criteria were met by 101 patients. Cystoscopies were performed in 46 patients and never altered the reimplantation. There were 20 preoperative, 90 intraoperative, and 61 postoperative urine cultures. Complications were associated with positive cultures of urine collected intraoperatively and postoperatively only. CONCLUSION Cystoscopies and asymptomatic urine cultures obtained before ureteral reimplantation provide no additional benefit while increasing cost for patients' families. Further research is needed to thoroughly identify the prudency of such practices in ureteral reimplantation for VUR.

Abstract
INTRODUCTION Near-total ear avulsion is a rare and challenging problem to repair with many techniques described; primary repair is an attractive option but is not always successful. Healing may be augmented with postoperative hyperbaric oxygen therapy (HBOT), but this technique is under-reported, and an ideal regimen is not known. The study objective is to discuss the role of HBOT in the management of ear avulsion by reviewing 2 unique cases. METHODS Case report and review of the literature. A Pubmed search using the terms ear avulsion and postoperative hyperbaric oxygen was performed. RESULTS Two pediatric patients presented with near-total avulsion of the auricle after suffering a dog bite. Various management options were discussed including observation, primary repair, post-auricular cartilage banking, graft reconstruction with periauricular tissue or rib cartilage, or microsurgical replantation. The decision was made to perform primary reattachment, followed by adjuvant hyperbaric oxygen therapy (HBOT). The patients achieved favorable esthetic results and continue to maintain the function of the reattached ear. Photo documentation was obtained throughout the process. DISCUSSION There is no consensus on the management of near-total ear avulsion. Primary repair is ideal from a cosmetic and ease-of-operation standpoint but does not always yield viable tissue. The use of postoperative HBOT is an attractive option that may boost success rates, but the ideal HBOT regimen is unknown. These cases represent a successful application of this innovative technique in a pediatric patient.

Abstract
OBJECTIVES Finger amputations can involve different levels of injury complexity, and the success of a finger replantation is further shaped by a variety of factors, including patient characteristics, surgical technique, and postoperative rehabilitation. These variables may interact in complex ways and contribute to heterogeneity that makes it challenging to guide management for individual patients. As such, this systematic review seeks review the outcomes of isolated single digit replantation and compare patient reported outcomes following revision amputation to guide decision making. METHODS The United States National Library of Medicine (PubMed/Medline), EMBASE and CINAHL were systematically searched to identify publications relevant to this systematic review. Related articles that were published from database inception to October 15, 2022 were extracted. The inclusion criteria consisted of English language clinical trials and observational studies reporting any functional or patient-reported outcome following single digit replantation. RESULTS From the initial 1050 titles and abstracts that were eligible for screening, six studies representing 550 single digit replantations were included. There were 162 replanted thumbs (162/550), as reported in three studies, and 388 replanted fingers (388/550), as reported in all six studies. Overall, all six studies concluded that non-thumb single digit replantation can provide satisfactory outcomes. Five studies suggested that single digit replantation proximal to flexor zone II can have reasonable outcomes in select cases. Two of the comparative studies (Zhu et al. [1], Chung et al. [2]) showed a statistically significant increase in MHQ score in the non-thumb replant group in comparison to the revision amputation group (87.6 versus 84.6 respectively). CONCLUSION When technically feasible, replantation is recommended, even in select index finger zone II amputations. Single digit replantation does not restore pre-injury hand function but does result in acceptable hand function when successful. Further study is needed to better inform risk-stratification of patients, and guide patient, and surgeon expectations for post-operative recovery. LEVEL OF EVIDENCE III.

Abstract
BACKGROUND Although replantation of amputated facial segments remains challenging in reconstructive surgery, it offers excellent aesthetic and functional outcomes. METHODS From May 2004 to October 2019, 12 patients underwent replantation of amputated facial tissues by supermicrosurgery. The case details, such as the rationale for replantation, the operation method, and postoperative therapy, are described. Four cases are discussed to demonstrate the replantation of different facial parts. RESULTS Facial tissue replantation was successful in all 12 patients without secondary surgery. The cases included the nose (1 patient), ears (8 patients), lips (2 patients), and one of the soft tissue segments surrounding the lower jaw. Venous congestion occurred in three patients who received a solitary arterial repair and were treated with bloodletting. All patients expressed satisfaction with the cosmetic and functional results at the final follow-up. CONCLUSIONS Supermicrosurgical facial tissue replantation is a promising and effective procedure for providing patients with the best aesthetic and functional outcomes.

Heterotopic Digital Replantation in Mutilating Hand Injuries: An Algorithmic Approach Based on 53 Cases and Literature Review. J Reconstr Microsurg 2023; 39:573-580.

Abstract
BACKGROUND Reconstruction of the mutilated hand is one of the most difficult challenges for hand microsurgeons. When multiple digits are amputated, orthotopic digital replantation of the available remnants may not adequately restore the hand function. In such cases, heterotopic digital replantation may provide a more functional reconstruction. METHODS Between 1997 and 2018, 53 patients with mutilating hand injuries were treated with heterotopic digital replantation at our institution. A retrospective chart review was conducted to determine the details of the injury, indications for heterotopic digital replantation, and functional outcomes. RESULTS In total, 173 digits were amputated from 53 patients (one patient suffered from bilateral hand injuries, so totally 54 hands). Sixty-eight digits underwent heterotopic digital replantation, 30 digits had orthotopic digital replantation, and 75 stumps were terminalized. The survival rate of digits treated by heterotopic digital replantation and orthotopic digital replantation was 83.8% (57/68) and 86.7% (26/30), respectively (p = 1). Tripod grip was achieved in 83.3% (45/54) of patients following replantation and optional secondary reconstructive surgeries. CONCLUSION Heterotopic digital replantation is a practical and reliable method for achieving optimal hand function following mutilating hand injuries. The basic principles are to restore a functional thumb in the first instance, followed by at least two adjacent fingers against which the thumb can oppose. This method is particularly indicated when orthotopic digital replantation of the available amputated parts would yield a suboptimal result.

Abstract
PURPOSE The replantation of multiple amputated digits is a technically challenging procedure for reconstructive surgeons that requires more time than the replantation of a single digit. We evaluated the effect of multiple-digit replantation on the success of digital replantation. METHODS Patients who experienced digital amputation and underwent digital replantation from January 2018 to December 2021 were studied retrospectively. Patients who experienced successful and failed replantation were compared, as were digits that survived or became necrotic after replantation. A multivariate logistic regression (MLR) analysis was performed to evaluate the independent factors of replanted digit survival. RESULTS There were 378 patients with 497 amputated digits who underwent digital replantation. Of all 378 patients, 298 underwent single-digit replantation, and the other 80 patients underwent multiple-digit replantation. A total of 83.3% of the replanted digits survived (414 of 497). Compared with patients with surviving replanted digits, significantly more patients with necrotic replanted digits underwent multiple-digit replantation (37.7% vs. 17.5%, p < 0.001). On the other hand, a digit that developed necrosis after replantation was more likely to have been involved in the replantation of three or more digits (16% vs. 29%, p = 0.005). The subsequent MLR analysis revealed that the likelihood of necrosis was 2.355 (p = 0.003) times higher in the replantation of three or more digits than in the replantation of one or two digits. CONCLUSION Patients who underwent multiple-digit replantation exhibited a higher incidence of necrosis in the replanted digits. In cases involving patients with multiple-digit amputation, it is crucial to prioritize and perform selective replantation based on the amputated digits.

Abstract
Amputation of the testis is very rare in clinical situations; therefore, most surgeons have no experience with an amputated testis. In this case, a 31-year-old male with schizophrenia amputated both testes due to self-mutilation. We performed replantation surgery via microscopy. On postoperative day 1, he removed his right testis by using his hand, even though his hands were restrained. The second attack disrupted the viability of the right testis. However, after proper management, we checked the normal sex hormone level by preserving the replanted left testis. We evaluated the viability of the replanted testis by performing five examinations, namely, intraoperative indocyanine green injection, testicular scan with technetium pertechnetate, contrast-enhanced computerized tomography, Doppler ultrasonography, and serum testosterone level. In this report, we aimed to describe our rare experience about management with replantation of the amputated testes and evaluation of their viability.

Abstract
BACKGROUND Ensuring the patency of repaired vessels is pivotal in improving the success rate of digit replantation. There is no consensus on how to best approach postoperative treatment for digit replantation. The influence of postoperative treatment on the risk of failure of revascularization or replantation remains unclear. QUESTIONS/PURPOSES (1) Is there an increased risk of postoperative infection with early discontinuation of antibiotic prophylaxis? (2) How are anxiety and depression affected by a treatment protocol consisting of prolonged antibiotic prophylaxis and administration of antithrombotic and antispasmodic drugs and by the failure of a revascularization or replantation procedure? (3) Are there differences in the risk of revascularization or replantation failure based on the number of anastomosed arteries and veins? (4) What factors are associated with failure of revascularization or replantation? METHODS This retrospective study was conducted between July 1, 2018, and March 31, 2022. Initially, 1045 patients were identified. One hundred two patients chose revision of amputation. In all, 556 were excluded because of contraindications. We included all patients in whom the anatomic structures of the amputated part of the digit were well preserved, and those with an ischemia time for the amputated part that did not exceed 6 hours. Patients in good health without any other serious associated injuries or systemic diseases and those without a history of smoking were eligible for inclusion. The patients underwent procedures that were performed or supervised by one of four study surgeons. Patients were treated with antibiotic prophylaxis (1 week); patients treated with antithrombotic and antispasmodic drugs were categorized into the prolonged antibiotic prophylaxis group. The remaining patients treated with antibiotic prophylaxis for less than 48 hours and no antithrombotic and no antispasmodic drugs were categorized into the nonprolonged antibiotic prophylaxis group. Postoperative follow-up was for a minimum of 1 month. Based on the inclusion criteria, 387 participants with 465 digits were selected for an analysis of postoperative infection. Twenty-five participants with a postoperative infection (six digits) and other complications (19 digits) were excluded from the next stage of the study, in which we assessed factors associated with the risk of failure of revascularization or replantation. A total of 362 participants with 440 digits were examined, including the postoperative survival rate, variation in Hospital Anxiety and Depression Scale scores, the association between the survival rate and Hospital Anxiety and Depression Scale scores, and the survival rate based on the number of anastomosed vessels. Postoperative infection was defined as swelling, erythema, pain, purulent discharge, or a positive bacterial culture result. Patients were followed for 1 month. The differences in anxiety and depression scores between the two treatment groups and the differences in anxiety and depression scores based on failure of revascularization or replantation were determined. The difference in the risk of revascularization or replantation failure based on the number of anastomosed arteries and veins was assessed. Except for statistically significant variables (injury type and procedure), we thought that the number of arteries, number of veins, Tamai level, treatment protocol, and surgeons would be important. A multivariable logistic regression analysis was used to perform an adjusted analysis of risk factors such as postoperative protocol, injury type, procedure, number of arteries, number of veins, Tamai level, and surgeon. RESULTS Postoperative infection did not appear to increase without prolonged use of antibiotic prophylaxis beyond 48 hours (1% [3 of 327] versus 2% [3 of 138]; OR 2.4 [95% confidence interval (CI) 0.5 to 12.0]; p = 0.37). Intervention with antithrombotic and antispasmodic therapy increased the Hospital Anxiety and Depression Scale scores for anxiety (11.2 ± 3.0 versus 6.7 ± 2.9, mean difference 4.5 [95% CI 4.0 to 5.2]; p < 0.01) and depression (7.9 ± 3.2 versus 5.2 ± 2.7, mean difference 2.7 [95% CI 2.1 to 3.4]; p < 0.01). In the analysis based on the failure of revascularization or replantation, the Hospital Anxiety and Depression Scale scores for anxiety (11.4 ± 4.4 versus 9.7 ± 3.5, mean difference 1.7 [95% CI 0.6 to 2.8]; p < 0.01) and depression (8.5 ± 4.6 versus 7.0 ± 3.1, mean difference 1.5 [95% CI 0.5 to 2.5]; p < 0.01) were higher in the failed revascularization or replantation group than in the successful revascularization or replantation group. There was no increase in the artery-related risk of failure (one versus two anastomosed arteries: 91% versus 89%, OR 1.3 [95% CI 0.6 to 2.6]; p = 0.53). For patients with anastomosed veins, a similar outcome was observed for the two vein-related risk of failure (two versus one anastomosed vein: 90% versus 89%, OR 1.0 [95% CI 0.2 to 3.8]; p = 0.95) and three vein-related risk of failure (three versus one vein anastomosed: 96% versus 89%, OR 0.4 [95% CI 0.1 to 2.4]; p = 0.29). Factors associated with failure of revascularization or replantation included the mechanism of injury (crush: OR 4.2 [95% CI 1.6 to 11.2]; p < 0.01, avulsion: OR 10.2 [95% CI 3.4 to 30.7]; p < 0.01). Revascularization had a lower risk of failure than replantation (OR 0.4 [95% CI 0.2 to 1.0]; p = 0.04). Treatment with a protocol of prolonged antibiotics, antithrombotics, and antispasmodics was not associated with a lower risk of failure (OR 1.2 [95% CI 0.6 to 2.3]; p = 0.63). CONCLUSION With proper wound debridement and patency of repaired vessels, prolonged use of antibiotic prophylaxis and regular antithrombotic and antispasmodic treatment may not be necessary for successful digit replantation. However, it may be associated with higher Hospital Anxiety and Depression Scale scores. Postoperative mental status is associated with digit survival. Well-repaired vessels, instead of the number of anastomosed vessels, could be critical to survival and decrease the influence of risk factors. Further research on consensus guidelines that compare postoperative treatment and the surgeon's level of expertise after digit replantation should be conducted at multiple institutions.

Abstract
BACKGROUND Fingertip amputations are common injuries presenting to the emergency room. However, all amputations do not have a chance of replantation, and composite graft is among the salvage treatments in this case. This treatment is both easy to apply and economical. Our study compares the success and cost of composite grafting in the emergency and operating rooms. METHODS Thirty-six patients who met the criteria were included in the study. The decision on the repair site was made by the sur-geon according to patient compliance and the intensity of the emergency clinic. Demographic and disease information of the patients were recorded. P<0.05 was accepted as the significance level. RESULTS Twenty-two cases were pediatric patients. Eighteen cases of crush injuries and 22 cases were treated in the emergency room. There was no significant difference in terms of complications, need for additional intervention, and short fingers related to interventions performed in the emergency room and operating room. Interventions in the emergency department were significantly lower in cost and shorter hospitalization times. There was no significant difference in terms of patient satisfaction. CONCLUSION Composite grafting is a simple and reliable method in fingertip injuries and gives satisfactory results in terms of patient satisfaction. In addition, composite graft application in fingertip injuries in the emergency department will both reduce the cost and prevent hospital infections that may occur due to the reduction in hospitalization.

Abstract
BACKGROUND Avulsion of the scalp is a rare destructive event worldwide. Before the emergence of microsurgery, skin transplantation, flap transplantation, greater omentum transplantation, and other methods were once widely used. However, replantation offers the optimum reconstruction. METHODS Six cases of complete avulsion injury of a large scalp treated from May 2017 to May 2020 were retrospectively analyzed. Under the microsurgery technology, the wound was cleaned and explored, and the appropriate arteriovenous anastomosis was selected. Preoperative blood preparation and skin preparation were actively performed. Postoperative strict nursing and observation of the blood supply of replanted scalp were performed. Regular outpatient follow-up after discharge was performed. RESULTS Replantation was successful in 5 cases and failed in 1 case, and in 1 case the occipital scalp (approximately 10% of the scalp area) died and crusted 2 months after the operation. After 6 to 24 months of follow-up, all patients were satisfied with the reconstructed appearance. CONCLUSIONS Superb microsurgical technique and more detailed anatomical knowledge are the key conditions for successful complete scalp avulsion replantation. Compared with other methods, successful replantation can achieve the best aesthetic and functional results.

Abstract
BACKGROUND Though common, postoperative hydronephrosis (POHN) following ureteroneocystostomy raises concern for an underlying obstruction. We aimed to determine the clinical significance of POHN following open (OUR) or robotic (RALUR) ureteral reimplantation. METHODS We retrospectively reviewed pediatric patients who underwent ureteral reimplantation for vesicoureteral reflux (VUR) from 2008 to 2019 by a single surgeon. Baseline characteristics, operative outcomes, and trends in POHN were assessed. POHN was defined as new onset hydronephrosis or exacerbation of pre existing hydronephrosis. Renal ultrasounds were performed 1, 4, and 12 months postoperatively. Voiding cystourethrograms were performed 4 months postoperatively. Surgical experience for RALUR cases was defined as number of ureters operated over time. RESULTS Altogether, 93 patients (127 ureters) underwent RALUR and 19 patients (26 ureters) underwent OUR. POHN was found in 27.6% and 30.8% of ureters after RALUR and OUR, respectively. Rate and time to POHN resolution for RALUR (91.4%, 112 days) and OUR (75%, 211 days) were statistically similar. Odds of POHN after RALUR were directly related with preoperative VUR grade (Range OR: 2.82[2.26-3.52]) and surgical experience (Range OR: 8.88[7.16-11.02]). Surgical experience was inversely related with odds of VUR recurrence (Range OR: 0.41[0.32-0.54]). Rates of VUR resolution were comparable for OUR and RALUR patients. No patient required additional intervention for POHN. CONCLUSIONS Incidence and resolution rate of POHN after OUR and RALUR were similar. Higher VUR grades were associated with increased odds of POHN after RALUR. Increasing RALUR experience improved VUR resolution rate but increased odds of POHN. Surgical success rates were similar for RALUR and OUR. LEVEL OF EVIDENCE II.

Abstract
We present a rare case of microsurgical replantation of a total scalp avulsion. A woman in her mid-60s was renovating a tractor when her hair was caught in a column drill resulting in traumatic scalp avulsion. The avulsed scalp involved the eyebrows and the entire hair-covered part of the scalp. The prehospital management and the conservation packing of the scalp was very effective. Microsurgical replantation was achieved with anastomoses of the left superficial temporal artery and one temporal vein on each side. The combination of the prehospital treatment and our university hospital setup made it possible to reattach the scalp with an ischaemia time of approximately 5 hours. A functional and aesthetically pleasing outcome was achieved, and the patient was discharged 6 days postoperatively with a vital scalp and no complaints. Five months postoperatively, she has no sign of alopecia and is regaining sensation and function of the scalp.A woman in her mid-60s was renovating a tractor when her hair was caught in a column drill resulting in traumatic scalp avulsion.

Abstract
BACKGROUND Aortic cusp fenestrations are common in patients with aortic root aneurysm, and their management during aortic valve repair remains controversial. We believe that fenestrations in the area of the commissures may rupture after reimplantation of the aortic valve because this operation increases the mechanical stress on the cusps. For this reason we have reinforced the free margin of the aortic cusp with fenestration with fine Gore-Tex sutures (WL Gore). This study examines the outcomes of reimplantation of the aortic valve in patients who had cusp fenestration reinforced with Gore-Tex sutures. METHODS A review of all patients who had reimplantation of the aortic valve for aortic root aneurysm disclosed 111 patients who had at least 1 cusp fenestration reinforced with a double layer of a fine Gore-Tex suture. The outcomes of these patients were examined and compared with a group of patients without fenestration using propensity score analysis. All patients were followed prospectively with images of the heart. RESULTS The median follow-up was 8.3 years. Overall the cumulative incidence of aortic valve reintervention at 15 years was 4.8% and the cumulative incidence of aortic insufficiency of moderate or severe degree was 9.2%. Comparison of outcomes of patients with and without fenestrations showed similar results up to 15 years of follow-up. CONCLUSIONS Reinforcement of the free margins of cusps with fenestrations using Gore-Tex sutures is safe and does not seem to adversely affect the durability of reimplantation of the aortic valve.

Abstract
Robot-assisted laparoscopic extravesical ureteral reimplantation (RALUR) and robotic ureteroureterostomy (RUU) are two mini-invasive surgical techniques that have begun to be performed in pediatric urology in recent years. RALUR has been employed especially for VUR treatment, while RUU is considered principally in case of complex doubled ureteral systems. Our aim is to discuss the safety and feasibility of these approaches in children, focusing on technical considerations and supporting their use in different anomalies and pathologies of the ureterovesical junction. We retrospectively collected data about 58 patients who underwent 44 dismembered RALUR (D-RALUR), 28 non-dismembered RALUR (ND-RALUR) and 5 RUU between May 2020 and December 2021. Indications for surgery were primary or secondary vesicoureteral reflux, megaureter, secondary UVJ obstructions, complicated doubled ureteral systems. Mean age was 3.5 years (range 0.6-12.9) and mean weight 17.1 (range 7.2-80). No intraoperative complications occurred nor conversion to open approach were reported. Major postoperative complications were reported in 11.7% of cases with a higher incidence for ND-RALUR. Mean hospital stay was 2.14 days (range 1-8). Success rate at the short-term follow-up was 91.9% for D-RALUR, 96.3% for ND-RALUR and 100% for RUU. RALUR and RUU are two feasible and safe procedures to perform in children. RALUR represents the most required and adequate technique in the treatment of UVJ pathologies, however, in selected cases RUU could represent an effective alternative that has to be considered.

COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:9631858. [PMID: 35813429 PMCID: PMC9262523 DOI: 10.1155/2022/9631858] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 06/06/2022] [Accepted: 06/10/2022] [Indexed: 11/18/2022]
Abstract
Objective After replantation of severed fingers in infants, the utility model patent upper limb restrictive brace-assisted bed rest braking, combined with psychological intervention, can alleviate children's anxiety, so as to reduce the occurrence of vascular crisis. Methods The study period was from April 2015 to July 2018. In this paper, 30 children with finger injuries in hand surgery in the CIS electronic medical record system of Cangzhou Integrated Traditional Chinese and Western Medicine Hospital were selected as the research objects. Replantation was performed in 30 infants with severed fingers. Among them, 15 cases were applied with the method of aircraft chest arm gypsum splint combined with sedative drug braking and the utility model patented product upper limb restrictive brace fixation-assisted bed rest braking, and the method of psychological intervention was applied at the same time. Results Among the 15 fingers in the control group, 6 had vascular crisis and 1 in the experimental group. The incidence of vascular crisis in the experimental group was lower, and the difference between the two groups was statistically significant (P < 0.05). The patients were followed up for 9~18 months, with an average of 9.72 ± 1.07 months. In the control group, 15 cases of severed fingers survived, and there were 13 cases of replantation finger necrosis in 2 cases of intractable arterial crisis. In the experimental group, 14 cases of severed fingers survived in 15 cases and there was 1 case of replanted finger necrosis in intractable arterial crisis after operation. There was no significant difference in the survival rate between the two groups (P > 0.05). In addition, the replanted finger function was evaluated. In the control group, 9 cases were excellent, 4 cases were good, and 1 case was fair. In the experimental group, 14 cases were excellent, 1 case was good, and 0 case was fair. The functional evaluation of the experimental group was better than that of the control group, and the difference between the two groups was statistically significant (P < 0.05). Conclusion For infants after replantation of severed fingers, the application of the utility model patented product upper limb restrictive brace can effectively make up for the insufficient fixation of aircraft chest arm gypsum splint, reduce the occurrence of vascular crisis, and assist children in bed. In addition, the application of psychological intervention can reduce children's postoperative crying and is conducive to children's postoperative recovery.

Abstract
INTRODUCTION Congenital ureterovesical junction (UVJ) obstructions quite rarely serve as an indication for ureteral reimplantation, and recurrent obstructions resulting from surgical treatment are even less frequent. Cases of acquired UVJ obstruction following endoscopy and ureteral reimplantation done for vesicoureteral reflux correction are fairly rare. The lack of known publications analyzing treatment of recurrent obstructive megaureter predetermines topicality of our research. PURPOSE Evaluate the efficiency and safety of extravesical anti-reflux uretero-cysto-anastomosis performed using Bradis technique for children with recurrent obstructive megaureter (OM). MATERIALS AND METHODS The work is based on the experience of surgical OM correction in 5 children aged 1 to 4 years, 4 boys and a girl with a recurrent UVJ obstruction following prior ureteral reimplantation for correction of UVJ obstruction (4 children) or vesicoureteral reflux (1 patient). Antenatal UVJ obstruction had been diagnosed in 2 patients. In all cases the examination included urine analysis, its culture study, ultrasonography of the kidneys and urinary tracts, dynamic renal scintigraphy, micturating cystography, and, where indicated, intravenous urography and SCT of the kidneys. All patients underwent Bradis extravesical reimplantation. RESULTS During postoperative care period, a considerable reduction of the dilatation of renal collecting system was accomplished in all five patients along with the differential renal function preserved on the pre-surgery level and a steady remission of urinary tract infection based on clinical manifestations and laboratory findings. CONCLUSIONS The simplicity of Bradis extravesical ureteral reimplantation represents its advantage over intravesical methods. Extravesical approach allows easy ureteral length and width correction. Limited experience of Bradis surgery in pediatric cases of recurrent OM requires confirmation with further randomized clinical trials.

Abstract
INTRODUCTION According to available data, there are only few articles describing pneumovesicoscopic (PNV) ureteral reimplantation (UR) for obstructive megaureter without tailoring and with ex vivo tailoring in children. AN OBJECTIVE To present our experience of the PNV UR using intravesical ureteral tailoring for symptomatic primary obstructive megaureter in children. STUDY DESIGN Between 2014 and 2020, 42 patients (mean age: 3.1 years) underwent a correction of primary obstructive megaureter (POM) via a vesicoscopic approach. Nine of them with the megaureter (diameter > 25 mm) underwent the intravesical ureteral tailoring. The analysis included only 9 patients who underwent intravesical tailoring of the ureter using the original technique. The dilated ureter is fixed intravesical by the loop in extended position. This simplifies the tailoring step of the ureter. The tailoring is performed by continuous suture (Star). RESULTS 43 UR were analyzed (1 bilateral, 1 with diverticulum, 1 with ureterocele). The mean operative time was 142 min (83-235 min). The mean manipulation time for intravesical tailoring of the megaureter was 18 min. After the surgery, the average kidney function doesn't reduce. We observed an increase in renal function by an average of 7% in three patients after the surgery. One patient required a conversion. It was in the early stages of mastering the technique. All patients underwent US 1-3 weeks 3-6-12 months after the operation, the size of the pelvic system and ureter decreased. Eight patients are asymptomatic, and only one has the clinical changes (a persistent leukocyturia, the size of the pelvic-ureteric segment, and the ureter remain unchanged or increased). According to the VCUG vesicoureteral reflux was detected in this case. An endoscopic correction used successful. DISCUSSION This possibility of applying our technique is confirmed according to folow-up data and should be used in other researches. The drainage of the ureter with an external stent for 1 month helps to form properly the neo-ureterovesical anastomosis and to prevent episodes of ureteral obstruction as a result the incidence of urinary tract infections reduces in the postoperative period. CONCLUSIONS The use of the Tuohy needle with the loop simplifies the fixation of the ureter. This helps to make the intravesical tailoring of the megaureter easier and faster. It is original and less traumatic for the ureter than existing methods.

Abstract
Cryopreservation has been applied in the replantation of limbs with a minimal amount of muscle tissue replanted. And small composite tissues have also been reported to be successfully replanted by preoperative cryopreservation. In this study, we aimed to study the effect of preoperative cryopreservation on digital survival after digit replantation. Accordingly, we collected and compared the demographic and clinicopathological characteristics of patients with digit injury of patients, and we observed no significant difference between the NT and CP patients of digital injury. We also investigated the records of successful digit replantation and other parameters which influenced the odds of digital survival of all recruited patients. Accordingly, we found that the number of survived digits was remarkably increased in patients in the CP group compared with that in patients in the NT group. And the number of patients requiring blood transfusion and the mean length of hospital stay were notably decreased in the CP group. And compared with other patient characteristics, the mechanism of injury (blade, crush, or avulsion) showed a remarkable difference between the two groups of digital failure. Moreover, we analyzed the correlations between patient characteristics and the odds of digit survival and found that compared with other basic characteristics of patients and their injury, the preservation temperature, especially cryopreservation, could significantly promote digital survival after replantation.

Abstract
The first digital replantation was performed over 50 years ago, and soon after surgeons in countries around the world were finding great success in their outcomes. The initial wave of success, however, has been followed by somewhat disappointing results in the United States in recent years. The steadily declining number of attempts at replantation and diminishing viability rates can be attributed to several factors, many of which can be addressed with centralization of care and the modification of our own indications and contraindications. While other regions of the world still enjoy good outcomes, the United States must make a concerted effort to improve their results for these devastating injuries.

Abstract
BACKGROUND Digit replantation under wide-awake local anesthesia is a challenging method, and there are only a few works of literature on this procedure. This article describes the authors' clinical experience in finger replantation under wide-awake local anesthesia compared to general anesthesia. METHODS Fifty-one patients who received single finger replantation after initial sharp amputation were included in the study, of whom 16 received wide-awake local anesthesia and 35 general anesthesia treatment. The indications for wide-awake local anesthesia were sharp amputation injury, estimated operation time less than 3 hours, and cooperative patients. The wide-awake local anesthesia was performed with 1% or 2% lidocaine infiltrated at the volar midpoint of the metacarpophalangeal joint of the affected digit without sedation medications. Demographic data included surgical outcome, waiting time, operation time, and hospital stay. RESULTS A total of 51 consecutive patients were included in this study. There were significantly shorter waiting times and operation times in the wide-awake local anesthesia group. The other parameters showed no significant differences. The overall success rate was 76.47 percent, with a mean overall operation time of 207 minutes. CONCLUSIONS In selected patients, finger replantation can be successfully performed under wide-awake local anesthesia, which has lower anesthesia risk and fewer medical expenses than general anesthesia. The method is feasible for single-digit replantation. Therefore, the finger replantation under wide-awake local anesthesia is a practicable alternative to general anesthesia. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Abstract
L´amputation du gland au cours de la circoncision est une complication tragique dont la responsabilité incombe à l´opérateur. Le traitement de référence de cette lésion repose sur la réimplantation microchirurgicale par anastomose vasculaire et nerveuse. Nous rapportons deux cas d´amputation totale du gland chez deux enfants: le premier âgé de cinq ans admis en urgence à la suite d´une circoncision et dont la réimplantation a été faite dans l´heure suivant l´accident, sans anastomose microchirurgicale; et le second était âgé de 11 ans reçu 3 ans après l´accident, géré psychologiquement jusque-là; il est en attente d´une chirurgie plastique. Le résultat obtenu après prise en charge du premier avait été jugé bon tant sur le plan urinaire, sur le plan de la sensibilité, de l´aspect cosmétique du gland et sur le plan érectile.

Abstract
OBJECTIVES To assess intermediate-term outcomes of aortic root replacement with valve-sparing reimplantation of bicuspid aortic valves (BAV), compared with tricuspid aortic valves (TAV). METHODS From January 2002 to July 2017, 92 adults underwent aortic root replacement with BAV reimplantation and 515 with TAV reimplantation at the Cleveland Clinic. Balancing-score matching based on 28 preoperative variables yielded 71 well-matched BAV and TAV pairs (77% of possible pairs) for comparison of postoperative mortality and morbidity, longitudinal echocardiogram data, aortic valve reoperation, and survival. RESULTS In the BAV group, 1 hospital death occurred (1.1%); mortality among all reimplantations was 0.2%. Among matched patients, procedural morbidity was low and similar between BAV and TAV groups (1 stroke in TAV group; renal failure requiring dialysis, 1 patient each; red cell transfusion, 25% each). Five-year results: Severe aortic regurgitation was present in 7.4% of the BAV group and 2.9% of the TAV group (P = .7); 39% of BAV and 65% of TAV patients had none. Higher mean gradients (10 vs 7.4 mm Hg; P = .001) and left ventricular mass index (111 vs 101 g/m2; P = .5) were present in BAV patients. Freedom from aortic valve reoperation was 94% in the BAV group and 98% in the TAV group (P = .10), and survival was 100% and 95%, respectively (P = .07). CONCLUSIONS Both BAV and TAV reimplantations can be performed with equal safety and good midterm outcomes; however, the constellation of higher gradients, less ventricular reverse remodeling, and more aortic valve reoperations with BAV reimplantations raises concerns requiring continued long-term surveillance.

Abstract
IMPORTANCE Risk-adjusted variation in surgeon outcomes has been traditionally explained by surgeon volume and hospital infrastructure, yet it is unclear how a surgeon's operative proficiency directly contributes to their patients' outcomes. OBJECTIVE To assess the variation of surgeons' operative proficiency and investigate its association with surgical outcomes. DESIGN, SETTING, AND PARTICIPANTS This case series was a retrospective analysis of all digit replantations and revascularizations at a single US university medical center between January 2000 and August 2020. Surgeons were assigned a proficiency score based on the expected procedure difficulty and outcomes from a sample of their cases. Surgeon proficiency scores were then used to determine associations with outcomes from subsequent cases. The expected difficulty of each case was calculated using a novel scoring system that applied pooled relative risks from a meta-analysis of risk factors for replantation and revascularization failure. EXPOSURES Digit replantation and revascularization. MAIN OUTCOMES AND MEASURES Digit survival at 1-month follow up (case success) and number of complications. RESULTS A total of 145 patients and 226 digits were treated by 11 surgeons with training in hand or microsurgery (mean [SD] age, 41.9 [15.2] years; 204 [90%] men); there were 116 replantations and 110 revascularizations. Surgeon proficiency scores ranged from 1.3 to 5.7, with a mean (SD) of 3.4 (1.4). Case success rates among surgeons varied from 20.0% to 90.5%, with a mean (SD) of 64.9%. Higher proficiency scores were associated with fewer case failures: each point increase was associated with 40% decreased odds of failure (odds ratio, 0.60; 95% CI, 0.38-0.94). Every 3-point increase in proficiency score was associated with 1 less complication (effect estimate, -0.29; 95% CI, -0.56 to 0.02). Surgeon proficiency score had a greater association with case failure than surgeon volume (16.7% vs 12.0%). The final model's association with case failure had an area under the receiver operating characteristics curve of 0.93. CONCLUSIONS AND RELEVANCE Operative proficiency varied widely among practicing surgeons and accounted for 17% of estimative ability for success of digit replantation and revascularization. Greater surgeon proficiency was associated with better outcomes, indicating that the value of surgical care may be optimized by improving surgeon proficiency.

Abstract
Injuries that result in thumb amputation cause a loss of 50% of hand function. Microsurgical replantation remains the gold standard of thumb reconstruction techniques. The non-microsurgical technical variants of thumb reconstruction described so far aim to create a neo-thumb of adequate length, stable, opposable, sensitive, and last but not least esthetically pleasing appearance. Avulsion of the distal phalanx and the absence of the nail will determine a functional deficit but also an unesthetic appearance. When replantation is not possible or the patient refuses to "sacrifice" another anatomical region for thumb reconstruction, the "reposition-flap" technique can be used. Although often controversial, this surgical technique deserves proper attention and should be used in some cases. We studied a group of 32 patients with distal thumb amputations. In patients with amputations in zone II according to Tamai, with interphalangeal joint preservation, the thumb was reconstructed using "reposition-flap" with an O'Brien flap in 15 cases. In the remaining 17 cases where the amputation was at the level of the interphalangeal joint, we used the same technique, but the thumb neopulp was reconstructed with the Littler heterodigital neurovascular flap harvested from the ulnar border of the middle finger in 11 cases or radial border of the ring finger in 6 cases. The results were evaluated from a functional (Kapandji score), sensitive (2-point discrimination, Semmes-Weinstein test) but also esthetically (patient satisfaction) point of view. Donor site morbidity, cold intolerance, the presence of nail dystrophy, and bone resorbtion were also assessed. The disabilities of the arm, shoulder and hand score was evaluated for each patient. Although various surgical and microsurgical techniques for thumb reconstruction are described, when choosing the technique to use we must first consider patient's wishes. A well-informed patient will be able to make, with the surgeon, the best decision for him concerning the reconstruction option.

Synovial Cell Count Before Reimplantation Can Predict the Outcome of Patients with Periprosthetic Knee Infections Undergoing Two-stage Exchange. Clin Orthop Relat Res 2021; 479:2061-2068.

Abstract
BACKGROUND Although synovial fluid can be used to diagnose periprosthetic joint infections (PJI) effectively, only the cutoff values adopted at the time of PJI diagnosis have been standardized, and few data are currently available about effectiveness of synovial fluid examination before definitive reimplantation. QUESTIONS/PURPOSES We asked: (1) What are the most appropriate thresholds for synovial fluid leukocyte counts (WBC) and neutrophil percentage (PMN percentage) in a patient group undergoing definitive reimplantation after an uninterrupted course of antibiotic therapy for chronic PJI? (2) What is the predictive value of our synovial WBC and PMN percentage threshold compared with previously proposed thresholds? METHODS In all, 101 patients with PJI were evaluated for inclusion from January 2016 to December 2018. Nineteen percent (19 of 101) of patients were excluded because of the presence of a chronic inflammatory disease, acute/late hematogenous infection, low amount of synovial fluid for laboratory investigations or infection persistence after spacer placement, and adequate antibiotic therapy. Finally, 81% (82 of 101) of patients with a median (range) age of 74 years (48 to 92) undergoing two-stage revision for chronic TKA infection, who were followed up at our institution for a period 96 weeks or more, were included in this study. The patients did not discontinue antibiotic treatment before reimplantation and were treated for 15 days after reimplantation if intraoperative cultures were negative. No patient remained on suppressive treatment after reimplantation. Synovial fluid was aspirated aseptically with a knee spacer in place to evaluate the cell counts before reimplantation. Thirteen percent (11 of 82) of patients had persistent or recurrent infection, defined as continually elevated erythrocyte sedimentation rate or C-reactive protein levels coupled with local signs and symptoms or positive cultures. The synovial fluid WBC counts and PMN percentage from the 11 patients with persistent or recurrent PJI were compared with the 71 patients who were believed to be free of PJI. Receiver operating characteristic (ROC) curve analyses assessed the predictive value of the parameters, and the areas under the curves (AUCs) were evaluated. The sensitivities, specificities, and positive and negative predictive values were determined for the WBC count and PMN percentage. Patients with persistent or recurrent infection had higher median WBC counts (471 cells/µL versus 1344 cells/µL; p < 0.001) and PMN percentage (36% versus 61%; p < 0.001) than did patients believed to be free of PJI. RESULTS ROC curve analysis identified the best threshold values to be a WBC count of 934 cells/µL or more (sensitivity 0.82 [95% CI 0.71 to 0.89], specificity 0.82 [95% CI 0.71 to 0.89]) as well as a PMN percentage of at least 52% (sensitivity 0.82 [95% CI 0.71 to 0.89] and specificity 0.78 [95% CI 0.67 to 0.86]. We found no difference between the AUCs for the WBC count and the PMN percentage (0.87 [95% CI 0.79 to 0.96] versus 0.84 [95% CI 0.73 to 0.95]. Comparing the sensitivities and specificities of the synovial fluid WBC count and PMN percentage proposed by other authors, we find that a PMN percentage more than 52% showed better predictive value than previously reported. CONCLUSION Based on our findings, we believe that patients with WBC counts of at least 934 and PMN percentage of 52% or more should not undergo reimplantation but rather a repeat debridement, as their risk of persistent or recurrent PJI appears prohibitively high. The accuracy of the proposed cutoffs is better than previously reported. LEVEL OF EVIDENCE Level III, diagnostic study.
