Zhang Q, Ding B, Wu J, Dong J, Liu F. Sonication fluid culture of antibiotic-loaded bone cement spacer has high accuracy to confirm eradication of infection before reimplantation of new prostheses. J Orthop Surg Res 2021; 16:377. [PMID: 34120643 PMCID: PMC8199841 DOI: 10.1186/s13018-021-02520-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2021] [Accepted: 06/02/2021] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND Sonication fluid culture of antibiotic-loaded bone cement spacer has been used to predict reinfection of two-stage revision, but its value remains disputable. This study aims to evaluate the association between the culture result of the sonicated spacer and the status of patients with periprosthetic joint infection receiving two-stage revision. MATERIALS AND METHODS A comprehensive electronic literature search was performed through four databases including PubMed, Embase/Ovid, and EBSCO, and the Cochrane Library to retrieve studies in which sonication fluid culture of the antibiotic spacer was conducted before reimplantation. The pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnostic odds ratio (DOR) were calculated to assess the association between the culture result of sonicated spacer and prognosis of the two-stage revision. RESULTS Eleven eligible studies comprising 603 artificial joints with PJI (134 suffering a clinical failure of two-stage revision) were included in the quantitative analysis. The pooled incidences of positive culture of sonicated spacer and intraoperative tissue were 0.14 (95% confidence interval [CI] 0.08-0.21) and 0.14 (95% CI 0.08-0.20), respectively. A positive culture of sonicated antibiotic-loaded bone cement spacer illustrated moderate sensitivity (0.31, 95% CI 0.13-0.58) but high specificity (0.94, 95% CI 0.86-0.98) for the diagnosis of therapeutic failure of two-stage revision; the pooled DOR was 7.67 (95% CI, 3.63-16.22). Meanwhile, the pooled sensitivity, specificity, and DOR of intraoperative tissue culture during the two-stage revision to predict therapeutic failure were 0.32 (95% CI, 0.20-0.47), 0.96 (95% CI, 0.92-0.98), and 10.62 (95% CI, 4.90-23.01), respectively. CONCLUSIONS Sonication fluid culture of antibiotic-loaded bone cement spacer revealed high accuracy for confirming eradication of infection before reimplantation of new prostheses and therefore could be used as a supplement for assessing therapeutic effect for PJI. However, both sonication fluid culture and intraoperative tissue culture from antibiotic-loaded bone cement spacer showed restricted yield for the prediction of a septic failure after the two-stage revision of PJI. Large-scale, prospective studies are still needed to testify current findings.

Influence of the level of arterial resection on the replanting and revascularization results in hand surgery: prospective study over 22 months. HAND SURGERY & REHABILITATION 2021; 40:660-669. [PMID: 34111576 DOI: 10.1016/j.hansur.2021.06.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Revised: 05/30/2021] [Accepted: 06/01/2021] [Indexed: 11/19/2022]
Abstract
The objective of this work was to assess whether the injury mechanisms are responsible for histological arterial lesions. This prospective single-center study included adults with wrist or hand arterial injury. Arterial resection of at least 2 mm from the proximal and distal stumps was performed before the arterial anastomosis. Histological analysis of the arterial stumps was performed. An ultrasound was performed 1 month postoperatively to check arterial patency. A clinical and functional evaluation was done at 1 month postoperative, then every 3 months. From 2018 to 2020, 46 patients were included with a maximum follow-up of 13 months. There were 35 cuts, 2 crush injuries, 8 amputation and 1 blast injury. Macroscopically, 37% of the margins were considered damaged. Histological analysis showed significant damage in 59% of the sections (27 out of 46 patients) with 50% for crush injury, 55% for cuts by mechanical tool, 62% for cuts by power tool, 62% for amputations and 100% for blasts. The failure rate was 9%: 2 replantations and 2 asymptomatic thromboses diagnosed by ultrasound. Postoperative pain on VAS was 1.75/10, range of motion was 87%, Quick DASH was 8%, SF36 PCS was 69% and SF36 MCS was 70%. Factors influencing the success or failure of anastomosis were the mechanism of injury (p = 0.02), associated nerve damage (p = 0.014) and length of proximal arterial cut (p = 0.046). Histological arterial lesions seem to correlate with the injury mechanism. Cuts caused by glass or crush injuries do not seem to require arterial resections of more than 2 mm. A continuation of the study with a larger number of subjects may generate statistically significant results.

Abstract
BACKGROUND Total ear amputation is a relatively rare trauma with an absolute indication for surgical treatment. Numerous techniques for auricular reconstruction have been described. When local and general conditions allow microsurgical replantation, this must be the first choice. We propose the association of microsurgical techniques with some modification (modified Baudet technique) to obtain higher survival rate of the reimplanted stump. METHODS This study included cases of 3 male patients with total ear amputation, the injuries and their mechanism (workplace accident) being identical. Chief complaints were pain, bleeding, important emotional impact due by an unaesthetic appearance. The established diagnosis was traumatic complete ear amputation (grade IV auricular injury according to Weerda classification). Microsurgical replantation was performed only with arteriorraphy, and no vein anastomosis. Cartilage incisions and skin excisions were made to enlarge the cartilage-recipient site contact area. Medicinal leeches were used to treat venous congestion, to which systemic anticoagulant therapy was added. RESULTS The results showed the survival of the entire replanted segment in all cases, with good function and esthetical appearance. Patients were fully satisfied with the final outcome. CONCLUSION Microsurgical replantation is the gold standard, for the surgical treatment of total ear amputation. We believe that cartilage incisions and the increased surface of contact between cartilage and recipient site has an adjuvant role in revascularization of the amputated stump (with only arterial anastomosis) and the use of hirudotherapy helps to relieve early venous congestion.

Abstract
This article discusses the contributions of the two pioneers of the surgical procedure of replantation-Ronald Malt in the US and Chen Zhongwei in China. Ronald Malt performed the reattachment surgery on a boy who had an accident in 1962, but he published his case report two years later in 1964. Chen Zhongwei performed a similar surgery on a worker who cut off his forearm in 1963, but he published his case report the same year. There is some debate about which one of these reputed surgeons should be given credit for being the first one to perform this breakthrough surgery, because although Malt was the first to perform the procedure, Zhongwei was the first to report it. To shed light on this controversy, criteria for scientific priority suggested by Ronald Vale and Anthony Hyman were applied. Although the criteria mainly favored Zhongwei as the pioneer of this procedure, he did not entirely fulfill one of the criteria. Therefore, the article could not present a definitive answer to the question, and it concludes by pointing out the highly commendable achievements and contributions of both Ronald Malt and Chen Zhongwei.

Abstract
OBJECTIVE The aim of this study was to analyze the outcomes of revision surgery following replantation of single digital amputations. METHODS In this study, first, a total of 403 patients (339 male, 64 female; mean age=28 years; age range=1-76) in whom a single finger replantation was performed were retrospectively reviewed, and then 60 patients with arterial or venous insufficiency in whom revision surgery was performed were reanalyzed. The second finger was observed to be the most injured one (32.8%). Injury type was classified as clean cut (25.3%), local crush (38.7), extensive crush (7.9%), and avulsion (28.1%). When taking the levels of injuries of the artery-only finger replantations into account, one finger (0.8%) was nail distal third, 70 fingers (56%) were nail distal third to lunula, 43 fingers (34.4%) were lunula to distal phalanx basis, 10 fingers (8%) were distal interphalangeal (DIP) joint, and one finger (0.8%) was middle phalanx. Operative revision was performed on 60 (14.9%) fingers. The need for operative revision was arterial insufficiency in 37 fingers (61.7%) and venous insufficiency in 23 fingers (38.3%). The average revision time was 43 (range=6-144) hours. While the average elapsed time for artery procedures was 35.3 (range=8-110) hours, the average elapsed time for vein procedures was 47.1 (range=6-144) hours. Finger survival rates were examined. Injury mechanism, amputation level, the number of artery/vein repairs and methods were examined in all patients and revision patients separately. RESULTS After the replantations, according to survival analysis, while 342 (84.9%) fingers were operated upon successfully, 61 (15.1%) fingers developed necrosis. In the patients with revision surgery, the survival rate was 78.3%. The need for revision was arterial insufficiency in 37 fingers (61.7%) and venous insufficiency in 23 fingers (38.3%). The revision rate was significantly lower than other injury types in clean-cut cases. In terms of levels of injury, no revisions were required from distal to lunula level, and the highest revision rate was observed at the proximal interphalangeal (PIP) joint level. CONCLUSION The results of the present study have shown that early re-exploration can provide a 78.3% success rate and can increase the survival rate from 67.6% to 84.2% following replantation of single digital amputations. Surgical re-exploration seems to be a reasonable salvage for replanted fingers with vascular insufficiency. LEVEL OF EVIDENCE Level IV, Therapeutic study.

Abstract
OBJECTIVE The aim of this study was to determine the effects of age and body mass index (BMI) on the functional outcomes, satisfaction rates, and recovery time after open debridement and reattachment surgery in non-athletic patients with insertional Achilles tendinopathy (IAT). METHODS In this retrospective study, 33 non-athletic patients (34 ankles) in whom open debridement and reattachment surgery was performed for IAT from 2006 to 2016 were included. Change in pain intensity was assessed using a Visual Analogue Scale (VAS) preoperatively and at the final follow-up. Functional assessment was done by preoperative and postoperative American Orthopaedics Foot and Ankle Score (AOFAS) and final follow-up Victorian Institute of Sport Tendon Study Group-Achilles Tendinopathy score (VISA-A). Patient satisfaction was evaluated by Roles - Maudsley score (RMS). The recovery time was defined as the time interval from the first appearance to postoperative relief of symptoms and recording. In addition, the recurrent Haglund's deformity was determined by postoperative control radiographs. RESULTS The mean age at the time of the operation was 51.19 years. The mean follow-up was 61.75±8.49 months. According to BMI, 5 patients were determined as morbid obese, 19 as obese, 3 as overweight, and 6 as normal. The mean VAS score significantly decreased from 8.5 preoperatively to 1.3 postoperatively (p<0.001). The mean AOFAS score significantly improved from 55.8 preoperatively to 92 postoperatively (p<0.001). Postoperative VISA-A score was 86% (range=32%-100%). According to RMS, 22 patients reported the result as excellent, 8 as good, 2 as fair, and 1 as poor. The mean recovery time was 11.8 (range=2-60) months, but one patient did not reach a symptom free status and thus was not included in the recovery time analysis. Postoperative control radiographs revealed signs of recurrence deformity in four patients. Recovery time showed a negative correlation with the age of the patients (r=-0.65). Postoperative scores and BMI showed no significant correlations with the recovery time on the basis of Spearman's rho test (p=0.196). CONCLUSION The results of this study have shown that open debridement and reattachment surgery may be an effective surgical method in relieving pain and improving functional status with high satisfaction rate and acceptable recovery time in the management of non-athletic patients with IAT. LEVEL OF EVIDENCE Level IV, Therapeutic study.

Abstract
OBJECTIVE To compare 2 minimally invasive surgical options for the treatment of obstructed megaureter: robot assisted dismembered extravesical cross-trigonal ureteral reimplantation (RADECUR) and laparoscopic dismembered extravesical cross-trigonal ureteral reimplantation (LDECUR). METHODS A 2 arm retrospective comparative study, including all pediatric patients who underwent ureteral reimplantation of unilateral obstructed megaureter, either by RADECUR or LDECUR. Patient demographics, perioperative surgical data, complications, and results are described. The surgical technique in both arms was similar: dismembering of the ureter, performing an extravesical cross-trigonal detrusorotomy, and intracorporeal tailoring of the ureter when indicated, were the pivotal maneuvers utilized. RESULTS The study included 95 patients (48 and 47 in the RADECUR and LDECUR arms, respectively) operated between the years 2016 and 2019. Overall, median age at surgery was 24 months (IQR 12-48) and median weight was 14 kg (IQR 11-21). Median operative time was 93 minutes (IQR 90-120) for RADECUR and 130 minutes (IQR 105-160) for LDECUR (P< 0.001). Intracorporeal excisional tapering was performed in 11 of the RADECUR patients and 19 LDECUR patients. Grade 1-2 Clavien-Dindo complications occurred in 7 patients, and grade 3 complication in 1 patient in the RADECUR arm. In the LDECUR arm, grade 1-2 complications occurred in 2 patients, and 2 had a grade 3 complications. Surgical success was achieved in 97% and 94% in the RADECUR and LDECUR groups, respectively. CONCLUSION Unilateral robotic extravesical cross-trigonal ureteral re-implantation for treatment of obstructed megaureter in the pediatric population is safe and effective both for RADECUR and LDECUR. Operative time is significantly shorter for RADECUR.

Abstract
Capsulectomy is a standard treatment for capsular contracture after breast augmentation. Incision via the endoscopic transaxillary approach is generally preferred by Asian women, but relevant literature addressing endoscopic transaxillary capsulectomy is limited. This study described the techniques of endoscopic transaxillary capsulectomy with reimplantation performed as a single-operator outpatient procedure. This retrospective study included patients with diagnosis of capsular contracture underwent endoscopic transaxillary capsulectomy with immediate reimplantation between January 1, 2013 and December 31, 2017. Data regarding history, implant type, operation time, duration of postoperative drainage, and complications were collected and analyzed. A total of 42 patients with a mean age of 36 years were included (11 unilateral and 31 bilateral capsulectomy). Total capsulectomy was performed on four (10%) patients for previous subglandular augmentation, and anterior capsulectomy was performed on 38 (91%) patients for previous submuscular augmentation. Mean sizes of previous and new (or reused) implants were 268 ml (median 283 ml, SD 57) and 317 ml (median 307 ml, SD 49), respectively. Mean operation time for unilateral and bilateral procedures were 4 h 15 min and 6 h 28 min, respectively. Postoperatively, mean duration of wound drainage was 10 (SD 3) days. Six (14%) patients experienced complications, including two (5%) patients with seroma, two (5%) with hematoma, one (2%) with infection, and four (10%) with recurrent capsular contracture. The four recurrent cases underwent repeat endoscopic transaxillary capsulectomy. All of the 42 patients had satisfactory clinical and esthetic outcomes. This study demonstrated the feasibility of endoscopic transaxillary capsulectomy with immediate reimplantation performed as an ambulatory surgery by a single surgeon who is in a stable and comfortable sitting position without the aid of a surgical assistant.

Abstract
RATIONALE The first successful ear replantation was performed by Pennigton in 1980 in Sydney. At least 84 ear replantations have been described in the literature over a period of 37 years since the first case. The authors have not found any previous case of frozen ear replantation in the literature. PATIENT CONCERNS We report the case of a 38-year-old man, who had an injury to the head while working with a machine. DIAGNOSIS The patient suffered total traumatic avulsion of the left ear. The ear was wrapped in moistened, sterile gauze and was transported on dry ice. At the time of admission to our department, the amputated ear was frozen to stiff, solid nonelastic matter. INTERVENTIONS We attempted replantation. Despite repeated arterial thrombosis during surgery, the ear was successfully replanted with arterial and venous anastomosis. OUTCOMES Venous congestion occurred within 9 h of surgery and was treated using leeches. Freezing cold injury developed during reattachment. The radix and proximal parts of the helix exhibited necrosis and so were reconstructed by contralateral conchal cartilage graft, which was wrapped with a local subauricular skin flap. On completion of treatment, a satisfactory shape was achieved, although the replanted and reconstructed left auricle slightly was smaller than the contralateral auricle. LESSONS LEARNED Our report confirms that the replantation of a frozen, amputated ear is possible, and we suggest that ear replantation should be the method of choice for the treatment of ear loss even under these conditions.

Abstract
An 86-year-old woman had a pacemaker implanted into a subfascial pocket. After four months, the generator became exposed, and the pacemaker was removed. She exhibited a lack of prepectoral tissue. We therefore performed reimplantation in collaboration with plastic surgeons. We placed the leads via the extrathoracic subclavian venous approach, and plastic surgeons created a subpectoral pocket from the low lateral side of the pectoralis major muscle. General cardiologists rarely create subpectoral pockets and they are unable to implant leadless pacemakers at their hospital due to lack of sufficient skill. Our case showed that creating a subpectoral pocket in collaboration with plastic surgeons is quick and safe.

Abstract
Successful penile replantations are rarely reported in the literature and are associated with significant complications. We present a case of a patient who auto-amputated his penis. Delayed microvascular replantation was performed approximately 14 hours following injury. He was treated with a phosphodiesterase inhibitor postoperatively, and adjuvant hyperbaric oxygen (HBO2) therapy was started 58 hours after replantation; 20 treatments at 2.4 atmospheres absolute (ATA), twice daily for eight days, followed by once daily for four days. Perfusion of the replanted penis was serially assessed using fluorescent angiography. With some additional surgical procedures including a split- thickness skin graft to the shaft due to skin necrosis he has made a complete recovery with return of normal urinary and sexual function. This unusual case illustrates the potential benefit of HBO2 therapy in preserving viability of a severed body part. Fluorescent angiography may have potential utility in monitoring efficacy of HBO2.

Abstract
Brachial plexus avulsion (BPA) occurs when the spinal nerve roots are pulled away from the surface of the spinal cord and disconnects neuronal cell body from its distal downstream axon, which induces massive motoneuron death, motor axon degeneration and de-innervation of targeted muscles, thereby resulting in permanent paralysis of motor functions in the upper limb. Avulsion injury triggers oxidative stress and intense local neuroinflammation at the lesioned site, leading to the death of most motoneurons. Berberine (BBR), a natural isoquinoline alkaloid derived from medicinal herbs of Berberis and Coptis species, has been reported to possess neuro-protective, anti-inflammatory and anti-oxidative effects in various animal models of central nervous system (CNS)-related disorders. In this study, we aimed to investigate the effect of BBR on motoneuron survival and axonal regeneration following spinal root avulsion plus re-implantation in rats. Our results indicated BBR significantly accelerated motor function recovery in the forelimb as revealed by the increased Terzis grooming test score, facilitated motor axon regeneration as evidenced by the elevated number of Fluoro-Gold-labeled and P75-positive regenerative motoneurons. The survival of motoneurons was notably promoted by BBR administration presented with boosted ChAT-immunopositive and neutral red-stained neurons. BBR treatment efficiently alleviated muscle atrophy, attenuated functional motor endplates loss in biceps and prevented the reduction of motor axons in the musculocutaneous nerve. Additionally, BBR treatment markedly mitigated the avulsion-induced neuroinflammation via inhibiting microglial and astroglial reactivity, up-regulated the expression of antioxidative indicator Cu/Zn SOD, and down-regulated the levels of nNOS, 3-NT, lipid peroxidation and NF-κB, as well as promoted SIRT1, PI3K and Akt activation. Collectively, BBR might be a promising therapy to assist re-implantation surgery for the treatment of BPA.

Abstract
Objectives: To describe our surgical technique of robotic ureteroileal reimplantation (RUIR) for ureteroileal anastomosis strictures with the use of near-infrared fluorescence imaging (NIFI) after transnephrostomic antegrade injection of indocyanine green in patients previously treated with robot-assisted radical cystectomy and intracorporeal orthotopic neobladder. Materials and Methods: From March 2015 to December 2017, 10 consecutive patients underwent RUIR in our tertiary referral center. All patients previously underwent percutaneous nephrostomy and at least one antegrade stenting and stricture dilatation attempt. Clinical data were prospectively collected into our institutional dataset. Both perioperative and functional outcomes were assessed. Results: Median time from robotic cystectomy to ureteroileal anastomosis strictures diagnosis was 5 months (interquartile range [IQR] 2-6). Median stricture length was 1.5 cm (IQR 1-2). Median operative time was 140 minutes (IQR 81-155), and median length of stay was 5 days (IQR 3-9). Two patients experienced Clavien grade 2 complications (urinary tract infection requiring antibiotics and blood transfusion, respectively). One patient underwent ileum resection and anastomosis due to bowel perforation (Clavien IIIb). At a median follow-up of 19 months (IQR 14-39), one patient developed a stricture recurrence. No patient developed worsening of renal function (newly onset chronic kidney disease stage 3b-4). Conclusions: Robotic reimplantation for ureteroileal anastomosis strictures is a safe and highly effective procedure, with a high success rate and excellent perioperative and functional outcomes. NIFI provides an easy guide to identify and progressively dissect the ureter.

Abstract
The authors describe 3 cases with successful fingertip replantations using supermicrosurgical arteriole (terminal branch of digital artery) anastomoses, arteriole graft obtained from the same fingertip defect, reverse arteriole flow to subdermal venule, and delayed venular drainage for venous congestion. Among these 16 consecutive distal phalangeal replantations, 7 fingers showed postoperative venous congestion (43.8% of the total fingers) and 5 were reoperated on with delayed venous drainage under digital block. All the reoperated fingers were successfully drained by additional single or double venous drainage with a vein graft (100% success rate). As a result, 13 fingers survived (81.3% success rate).

Abstract
Background/aim Venous insufficiency after replantation or revascularization is one of the most common causes of limb loss in either the short or the long term. The aim of this study was to evaluate the results of a new technique to overcome venous insufficiency. Materials and Methods A crush-avulsion type of injury was formed in the femoral veins of rats of 3 separate groups. In the control group, primary repair was applied to the damaged veins and the remaining 2 groups were repaired with either an arterial graft or a vein graft. The success rates of anastomosis were then compared. Results In the control group the patency rate was 25% in the 2nd hour, 12.5% on the 2nd day, and 12.5% on the 10th day. The patency rate in the vein group was 87.5% in the 2nd hour, 50% on the 2nd day, and 37.5% on the 10th day, whereas the patency rates in the artery group were 100% in the 2nd hour, 87.5% on the 2nd day, and 75% on the 10th day. Conclusion Microsurgery requires experience and patience. It can be considered that the use of arterial grafts for venous repair in replantation after crush-avulsion type amputations can increase the success rate of replantation.

Abstract
PURPOSE We describe our technique for using intraureteral and intraurinary diversion indocyanine green (ICG) during robotic ureteroenteric reimplantation and report our outcomes. METHODS We retrospectively reviewed eight patients who underwent ten robotic ureteroenteric reimplantations between August 2013 and July 2017. ICG was injected antegrade and/or retrograde into the lumen of the ureter, and retrograde into the lumen of the urinary diversion. All patients consented to off-label use of ICG. Postoperatively, all patients were assessed for: clinical success: the absence of flank pain; and radiological success: the absence of obstruction on renal scan and/or loopogram. RESULTS Visualization of ICG under near-infrared fluorescence allowed for precise identification of the strictured ureter and urinary diversion, which fluoresced green; and localization the ureteroenteric stricture margins, which poorly fluoresced green. The median operative time was 208 min (IQR 191-299), estimated blood loss was 125 ml (IQR 69-150), and length of stay was 6 days (IQR 1-8). Three of eight (37.5%) patients suffered a minor (Clavien ≤ 2), and 2/8 (25.0%) patients suffered a major (Clavien > 2) post-operative complication. There were no complications related to ICG use. At a median follow-up of 29 months (IQR 21-38), 8/10 (80.0%) ureteroenteric reimplantations were clinically and radiologically successful. CONCLUSIONS Intraureteral and intraurinary diversion ICG may be utilized as a real-time contrast agent during robotic ureteroenteric reimplantation to assist with identification of the strictured ureter and urinary diversion, and delineation of the ureteroenteric stricture margins. Despite this, RUER remains a technically difficult and morbid procedure.

Abstract
The Procedure of the subclavian flap angioplasty and reimplantation of the distal subclavian artery into the left carotid artery was used in 2 infants( 4-month-old and 5-month-old) with recurrent coarctation of the thoracic aorta through the median sternotomy. After median sternotomy, the aortic arch and its branches were extensively dissected. The descending aorta was minimally dissected. An arterial cannula was inserted into the brachiocephalic artery and the cardiopulmonary bypass was started by bicaval cannulation. The aortic root cannula was inserted into the aortic root and T-connected with the side hole of the brachiocephalic arterial cannula. The 2 cases underwent surgery with selective cerebral and myocardial perfusion. The left subclavian artery was transected and the subclavian flap technique was used to enlarge the recoarctation of the thoracic aorta. Then, the distal end of the transected left subclavian artery was reconstructed by performing an end to side anastomosis to the left carotid artery. This procedure has several advantages;(1) minimal dissection of the descending aorta is required,(2) the use of prosthetic material is avoided, (3) it prevents ischemic arm complication, (4) additional skin incision is avoided.

Abstract
INTRODUCTION Endoscopic injection of a bulking agent is a common first-line approach to the treatment of vesicoureteral reflux (VUR). While early outcomes are comparable to open ureteroneocystotomy, 5-25% of children will eventually develop recurrent reflux necessitating repeat injections or open ureteral reimplantation. OBJECTIVE To determine whether prior endoscopic injection of a bulking agent impacts outcomes of subsequent open ureteral reimplantation. STUDY DESIGN Using a retrospective cohort design, radiographic and clinical outcomes of open ureteral reimplantation were compared between patients with and without prior endoscopic correction of reflux. Surgical and hospitalization data were also compared between groups and a cost comparison was performed to assess differences in healthcare costs between the two cohorts. Units of analysis included total ureters or total patients. For certain variables, subanalysis of unilateral versus bilateral reimplantation was included. RESULTS A total of 258 patients underwent open reimplantation for VUR between 2007 and 2016 by five pediatric urologists. Final analysis (see Summary Table) included 192 patients with pre-operative and postoperative voiding cystourethrogram (VCUG) and follow-up data at a median 4.95 months. Among 317 reimplanted refluxing ureters, radiographic resolution was reached in 26/27 (96.3%) patients with and 279/290 (96.2%) without prior endoscopic treatment (P = 0.981). Clinical success was achieved in 17/17 (100%) patients with and 174/175 (99.4%) without prior endoscopic treatment (P = 0.755). There were no statistically significant differences between duration of surgery or length of hospital stay. There were no statistically significant differences between total charges, total costs, and operating room (OR) costs between groups. DISCUSSION This study indicated that prior endoscopic injection of a bulking agent did not impact the outcomes or costs of subsequent open ureteroneocystotomy. While prior studies have demonstrated tissue changes associated with injection of a bulking agent, these did not seem to significantly impact the difficulty of later open surgery or the success rates compared to patients who proceeded directly to open correction of reflux. CONCLUSION Open ureteral reimplantation for recurrent VUR after failed endoscopic injection of a bulking agent was safe and effective, with comparable outcomes and costs to open surgery in patients without prior endoscopic correction.

Abstract
INTRODUCTION Thrombosis is the most common complication of thrombocytosis, which can be particularly damaging to reattached digits. We present a guideline about digital replantation when thrombocytosis is expected. CASE PRESENTATION We report a case of an 18-year-old man who sustained a traumatic amputation of two fingers and splenic rupture in a traffic accident. He underwent digital replantation the day after splenectomy when life-threatening conditions had been managed. The platelet count increased to over 1,300,000/mm and post-splenectomy reactive thrombocytosis was diagnosed. Hydroxyurea and anagrelide were administered to control the platelet count after consultation with a hematologist. The reattached fingers survived without any complication. CONCLUSION In patients with digital amputation, replantation can be attempted, even when thrombocytosis is expected, when requested by the patient. Furthermore, the platelet count should be actively controlled with medication to improve the survival rate of the reattached finger.

Abstract
BACKGROUND Digital replantation has become a well-established technique that has revolutionized hand surgery. One of the most important factors to a successful replantation is less than 12 hours of warm and 24 hours of cold ischemia time. The purpose of this article was to present a concept of door-to-surgery time and test the hypothesis that success in distal digital replantation is associated with this time. METHODS Forty-five patients with 49 distal amputations were included in the study. Data regarding patient demographics, amputation characteristics, ischemia time, and surgical outcome were collected. Factors related to a successful replantation were analyzed. Fisher's exact test was used for statistical analysis. RESULTS Type I, II, and III Yamano classification were noted in 11 (22.4%), 11 (22.4%), and 27 (55.1%) amputations. All the digits had arterial anastomoses while 19 (38.8%) digits were replanted without venous anastomosis. The mean door-to-surgery time was 229 minutes. The overall success rate was 77.6%. There were no differences in the survival rates between replantations with or without venous anastomosis. Patients with less than 180 minutes of door-to-surgery time had a significantly better survival rate compared to patients with greater time. CONCLUSION The overall success rate was 77.6%. Patients with less than 180 minutes of door-to-surgery time had a significantly greater success rate (95.0%) compared to patients with longer door-to-surgery time (65.5%). Further effort must be made to achieve this goal in digital replantation.

Abstract
The risk factors of hypoparathyroidism after total thyroidectomy (TT) with central lymph node dissection (CND) have not been completely defined. The aim of the study was to evaluate the risk factors of hypoparathyroidism after the surgery.We retrospectively reviewed our patients who underwent TT and CND (including lateral lymph node dissection) for thyroid carcinoma between January 2013 and June 2016. According to the postoperative serum levels of parathyroid hormone within 6 months, the patients were divided into normal, transient hypoparathyroidism, and permanent hypoparathyroidism groups. The clinicopathologic characteristics and surgical details were compared among the 3 groups. The risk factors of hypoparathyroidism were investigated by univariate and multivariate analyses.Of the 903 patients, 399 (44.2%) were found to have transient hypoparathyroidism and 10 (1.1%) had permanent hypoparathyroidism. On multivariate analysis, female gender (P < .001), nonuse of carbon nanoparticles (P = .038), parathyroid autotransplantation (P < .001), accidental parathyroid resection (P = .004), and bilateral CND (BCND, P = .003) were the independent risk factors of transient hypoparathyroidism; nonuse of carbon nanoparticles (P = .041) and a tumor in the upper pole of thyroid gland (P = .031) were the independent risk factors of permanent hypoparathyroidism. Patients with transient hypoparathyroidism were more likely to develop permanent hypoparathyroidism when they had hypertension (P = .026) and a tumor in the upper pole of thyroid gland (P = .010).Precise surgical techniques and carbon nanoparticles suspension should be applied for in situ preservation of parathyroid glands (PGs) in thyroid carcinoma patients, especially in females with hypertension and a tumor in the upper pole of thyroid gland. Autotransplantation is only performed when a PG is resected inadvertently or devascularized. TT with BCND should be better performed by an experienced surgeon to reduce the incidence of hypoparathyroidism.

Abstract
PURPOSE To evaluate the long-term outcomes of laparoscopic ureteral reimplantation with extracorporeal tailoring and direct nipple ureteroneocystostomy for adult obstructive megaureter and compare the results with the open procedure. METHODS From January 2007 to July 2013, 22 patients underwent laparoscopic and 28 patients underwent open ureteral reimplantation for adult obstructive megaureter. For laparoscopic group, the dilated ureter was delivered out of through a 12-mm port and the distal end was tailored and formed into an antireflux nipple extracorporeally. The ureteral nipple was intracorporeally reimplanted into the posterolateral wall of the bladder. Demographics, complications and follow-up data were analyzed and compared retrospectively between the groups. RESULTS Baseline characteristics including age, gender, body mass index, affected side, age at diagnosis and follow-up time were statistically similar for the groups. All of the surgeries were performed successfully, and no major complications occurred. Comparing with the open group, the use of our novel laparoscopic procedure resulted in less estimated blood loss (50.0 vs. 71.0 ml; P = 0.001), less narcotic analgesic (3.0 vs. 18.0 mg; P = 0.01) and shorter hospital stay (5.1 vs. 7.9 days; P < 0.001). Long-term outcomes including rates of recurrent ureteral stricture (4.5 vs. 0%; P = 0.25), rates of vesicoureteral reflux (9.1 vs. 3.6%, P = 0.42) and success rates (86.4 vs. 96.9%; P = 0.45) did not significantly differ between the two groups. CONCLUSION Laparoscopic ureteral reimplantation with extracorporeal tailoring and direct nipple ureteroneocystostomy is a safe and equally effective as the open surgery for the long-term outcomes of adult obstructive megaureter.

Abstract
BACKGROUND Malignant bone tumors themselves and the wide resection required because of them may cause huge bone defects in the bone segment involved. Autologous bone grafts are a reliable option to cover these defects in many cases but their availability is limited. Besides common alternative reconstruction methods, including the use of allografts and/or prostheses, especially extracoroporeal irradiation (ECI) and reimplantation of the bone segment involved is attracting increasingly more attention nowadays. DISCUSSION In the following, we report on indications/contraindications, details of the operative technique, as well as the recommended rehabilitation regime of ECI. Furthermore, we compare our own results with those published in the recent literature. Especially the advantages and disadvantages of this method, the risks and the complications are illustrated and critically discussed. CONCLUSION Extracorporeal irradiation of a tumor bearing bone segment is a valuable alternative reconstruction technique following tumor resections of the pelvis, femur and tibia, with encouraging results with respect to local control, complication risks and functional outcome.

Abstract
OBJECTIVES To report our initial experience with laparoscopic Boari flap ureteral reimplantation and to review the main technical elements in ureteral reconstructive surgery. METHODS In a 10-year period we performed 23 laparoscopic ureteral reimplantations. Three cases required a Boari flap. Two patients presented ureteral stenosis above the iliac vessels and the third one a urothelial tumor of the pelvic ureter. RESULTS Two cases were completed laparoscopically; the third one was electively converted to open surgery to avoid prolonged OR time. Mean operative time was 276 minutes (270-290 min). There were no intraoperative complications. Mean hospital stay was 6.6 days. One patient presented postoperative UTI (Clavien 2). One patient developed with history of sever arteriopathy and aortorenal by pass developed ureteral stenosis proximal to the ureteral reimplantation eight months after the operation. CONCLUSIONS Laparoscopic Boari flap ureteral reimplantation is an affective technique for ureteral reconstruction, safe and reproducible, reserved for cases of ureteral pathology in which the distance to bridge between the bladder and the ureteral stump is long.
