Transplanting horseshoe kidneys is challenging and has higher complication rates due to the unusual anatomy of the vascular and urinary collecting systems. Most centers avoid using these kidneys for transplantation. However, if chosen carefully, these organs can be used successfully to reduce organ shortage. In this paper, we will describe the technique of procurement of horseshoe kidneys from cadaveric donors, back table preparation, and its successful implantation in a recipient. With good planning and skillful surgical techniques, horseshoe kidneys can be successfully transplanted in suitable recipients. If properly selected, these kidneys can be used to reduce the organ scarcity and diminish waitlist morbidity and mortality.

Introduction. The surgical techniques currently available for penile reconstruction for trans-men with gender dysphoria present with multiple drawbacks and often fail to meet patients’ expectations. Literature reports three cases where penile transplantation has been performed for cis-men, with the last two cases being considered successful. Aim. To determine whether an en bloc surgical dissection can be performed in a male cadaver, in order to include structures necessary for penile transplantation (from a deceased donor male) to a recipient with female genitalia in gender affirmation surgery. Method. The study was conducted in the form of explorative dissections of the genital and pelvic regions of three male cadavers preserved in phenol-ethanol solution. Results. The first two dissections failed to explant adequately all the relevant structures. The third dissection, which was performed along the pubic arch and through the perineum, succeeded in explanting the relevant structures: it, in fact, allowed for identification and adequate transection of urethra, vessels, dorsal nerves, crura of corpora cavernosa, and bulb of corpus spongiosum, in en bloc explantation of male genitalia. Conclusions. It is possible to explant the penis and associated vessels, nerves, and urethra en bloc from a cadaver. This study suggests a surgical technique for en bloc explantation aiming for transplantation of the penis from a cadaveric donor male to a recipient with female genitalia.

Bladder Cancer Recurrence

Bladder cancer remains one of the most common malignancies of the genitourinary tract. Transurethral resection of the bladder tumor (TURBT) via cystoscopy with examination under anesthesia remains the primary method for determining the diagnosis and clinical stage of bladder cancer. Given the substantial cost of treatment and risk of bladder cancer recurrence after TURBT, novel approaches to transurethral resection, such as the en bloc technique, have been developed in an attempt to address these limitations. In this review, we examined the postoperative and oncological outcomes of en bloc TURBT compared to traditional resection techniques. Further prospective clinical studies, however, are still necessary to determine whether these alternative technologies or surgical techniques may improve treatment in bladder cancer patients. Level of evidence: Not applicable.

Background: When conservative management fails, patients with stress urinary incontinence (SUI) are considered for surgical treatment. Simpler, more economical and less invasive surgical techniques, such as the Remeex® system, have been developed. Objectives: To analyze the objective effectiveness of the Remeex® system in the treatment of male stress urinary incontinence. To study survival and complication rates of the Remeex® system in male SUI patients. Materials and methods: Prospective observational study between July 2015 and May 2020. Group A (n = 7; GA) patients with mild SUI. Group B (n = 22; GB) patients with moderate SUI. Group C (n = 18; GC) patients with severe SUI. Effectiveness was assessed by the number of patients achieving complete and partial dryness. Complete dryness was defined as patients using 0–1 safety pads per day; partial dryness as a >50% reduction in the number of pads used. Results were analyzed using descriptive statistics, Student’s t-test. Chi2, Fisher’s exact test, ANOVA, and multivariate analysis. Significance was set at p < 0.05. Results: Mean age 69.76 years, mean follow-up 33.52 months. Objective effectiveness was observed in 89.36% of patients with incontinence. The effectiveness was 85.71% in GA, 90.91% in GB and 88.89% in GC. There were no significant differences among groups (p = 1.0000). 34.04% of patients with an implant required at least one readjustment, while 66.00% did not require any. There were no significant differences among groups (p = 0.113) Chi2 = 4.352. 95.74% of implants remained in place by the end of follow-up. We observed complications in 17.02% of patients. Conclusions: Remeex® system is an effective and safe method for male stress urinary incontinence treatment, regardless of the severity of the incontinence, with high survival and low complication and removal rates. System readjustments are required in one-third of the cases.

Gastrointestinal Lesions

<b><i>Background:</i></b> Endoscopic resection of dysplastic lesions in early stages of cancer reduces mortality rates and is recommended by many national guidelines throughout the world. Snare polypectomy and endoscopic mucosal resection (EMR) are established techniques of polyp removal. The advantages of these methods are their relatively short procedure times and acceptable complication rates. The latter include delayed bleeding in 0.9% and a perforation risk of 0.4–1.3%, depending on the size and location of the resected lesion. EMR is a recent modification of endoscopic resection. A limited number of studies suggest that larger lesions can be removed en bloc with low complication rates and short procedure times. Novel techniques such as endoscopic submucosal dissection (ESD) are used to enhance en bloc resection rates for larger, flat, or sessile lesions. Endoscopic full-thickness resection (EFTR) is employed for non-lifting lesions or those not easily amenable to resection. Procedures such as ESD or EFTR are emerging standards for lesions inaccessible to EMR techniques. <b><i>Summary:</i></b> Endoscopic treatment is now regarded as first-line therapy for benign lesions. <b><i>Key Message:</i></b> Endoscopic resection of dysplastic lesions or early stages of cancer is recommended. A plethora of different techniques can be used dependent on the lesions.

Heart and heart-lung transplantation have been established as effective treatments for a wide variety of end-stage cardiopulmonary diseases. Recent years have seen refinements in surgical techniques for cardiopulmonary replacement as well as the selection and postoperative care of thoracic transplant recipients. Despite substantial clinical progress, however, significant problems remain, particularly donor organ shortage, graft rejection, opportunistic infection, and limited organ preservation techniques. Basic and clinical research are currently addressing these problems. In this brief review, we provide an update of our experiences with heart and heart-lung transplantation in the West (particularly at Stanford University), an outline of the active issues in the field, and some thoughts about the development of thoracic transplantation in Asia.

OBJECT A chordoma is an indolent primary spinal tumor that has devastating effects on the patient's life. These lesions are chemoresistant, resistant to conventional radiotherapy, and moderately sensitive to proton therapy; however, en bloc resection remains the preferred treatment for optimizing patient outcomes. While multiple small and largely retrospective studies have investigated the outcomes following en bloc resection of chordomas in the sacrum, there have been few large-scale studies on patients with chordomas of the mobile spine. The goal of this study was to review the outcomes of surgically treated patients with mobile spine chordomas at multiple international centers with respect to local recurrence and survival. This multiinstitutional retrospective study collected data between 1988 and 2012 about prognosis-predicting factors, including various clinical characteristics and surgical techniques for mobile spine chordoma. Tumors were classified according to the Enneking principles and analyzed in 2 treatment cohorts: Enneking-appropriate (EA) and Enneking-inappropriate (EI) cohorts. Patients were categorized as EA when the final pathological assessment of the margin matched the Enneking recommendation; otherwise, they were categorized as EI. METHODS Descriptive statistics were used to summarize the data (Student t-test, chi-square, and Fisher exact tests). Recurrence and survival data were analyzed using Kaplan-Meier survival curves, log-rank tests, and multivariate Cox proportional hazard modeling. RESULTS A total of 166 patients (55 female and 111 male patients) with mobile spine chordoma were included. The median patient follow-up was 2.6 years (range 1 day to 22.5 years). Fifty-eight (41%) patients were EA and 84 (59%) patients were EI. The type of biopsy (p < 0.001), spinal location (p = 0.018), and if the patient received adjuvant therapy (p < 0.001) were significantly different between the 2 cohorts. Overall, 58 (35%) patients developed local recurrence and 57 (34%) patients died. Median survival was 7.0 years postoperative: 8.4 years postoperative for EA patients and 6.4 years postoperative for EI patients (p = 0.023). The multivariate analysis showed that the EI cohort was significantly associated with an increased risk of local recurrence in comparison with the EA cohort (HR 7.02; 95% CI 2.96–16.6; p < 0.001), although no significant difference in survival was observed. CONCLUSIONS EA resection plays a major role in decreasing the risk for local recurrence in patients with chordoma of the mobile spine.

Purpose: A systematic review of all patients that have been reported in the literature with abdominal aortic aneurysm (AAA) concomitant with horseshoe kidney (HSK) treated electively by endovascular aneurysm repair (EVAR) is presented. A new grouping system for describing HSK vasculature is implemented. Materials and Methods: We searched for published manuscripts using the Medical Subject Headings terms “abdominal aortic aneurysm,” “AAA,” “EVAR,” “endovascular aneurysm repair,” and “horseshoe kidney” in PubMed, Google Scholar, Scopus, and National Center for Biotechnology Information databases. Inclusion criteria include all published material of patients with AAA with HSK treated electively by an endovascular approach. We excluded patients who were treated by a hybrid or open repair or patients with ruptured AAA. Statistical analysis was carried out using SPSS Statistics version 25 (IBM Corp, Armonk, New York) software. Results: A total of 50 patients from 30 studies were included for analysis. Males made up 88% (n=44) of the population. The median age for this cohort was 70 years (range: 47–86 years). Median aneurysmal diameter was 6.0 cm (range: 4.0–10.3 cm). The median operative time for endovascular repair was 84 minutes (range: 40–332 minutes). The most common graft used was Zenith, used in 40% (n=20) of the cases, followed by Endurant in 14% (n=7). The overall complication rate was 14% (n=7). The median follow-up was 19 months (range: 1–108 months). While comorbidities did not appear to impact outcomes significantly, median operative times for smokers were higher than those in nonsmokers, 84 versus 118 minutes, respectively (p=0.048). Univariate linear regression modeling of aneurysmal size with age, operative time, and length of stay revealed a significant coefficient association between aneurysmal size and operative times. After adjusting for comorbidities and aneurysmal size, prior history of chronic kidney disease significantly increased odds for renal infarction. Conclusion: This review presents the most complete data set possible of patients with concomitant HSK and AAA treated by an endovascular approach. Furthermore, the A + B + C classification for grouping the HSK vasculature is implemented. This systematic review suggests EVAR to be an excellent option with low complication rates for the treatment of AAA in patients with HSK.

Purpose To compare two common surgical techniques of epiphysiodesis: drill/curettage epiphysiodesis (PDED) versus cross screw epiphysiodesis (PETS). The hypothesis is that the two techniques have similar efficacy but demonstrate differences in length of hospital stay (LOS), time to return to activity and complication rates. Methods A retrospective review of growing children and adolescents less than 18 years old who required an epiphysiodesis with leg-length discrepancy (LLD) of 2 cm to 6 cm with minimum two years of follow-up was conducted. Characteristics including age at surgery, gender, epiphysiodesis location, side, operative time, LOS and hardware removal were compared across treatment groups. LLD, expected growth remaining (EGR) and bone age were determined preoperatively and at most-recent visit. The correction ratio (change in EGR) was calculated along with a 95% confidence interval (CI) to assess if correction in leg length was achieved. Results A total of 115 patients underwent epiphysiodesis in the femur (53%), tibia (24%) or a combination (24%). The cohort was 47% male, with a mean age of 12.6 years (7.7 to 17.7) at surgery. Median follow-up was 3.7 years (2.0 to 12.7). In all, 23 patients underwent PETS and 92 patients had PDED. Both treatment groups achieved expected LLD correction. There was no significant difference in median operative time, complication rates or LOS. PETS patients returned to activity at a mean 1.4 months (interquartile range (IQR) 0.7 to 2.1) while PDED patients returned at a mean 2.4 months (IQR 1.7 to 3) (p < 0.001). Conclusion Effectiveness in achieving expected correction, LOS and operative time are similar between screw and drill/curettage epiphysiodesis. Patients undergoing PETS demonstrated a faster return to baseline activity than patients with PDED. Level of Evidence: III

The Impact

Background: Breast reconstruction has a positive impact on body image and quality of life for women after experiencing the physically and psychologically demanding process of mastectomy. Previous studies have presented body mass index (BMI) as a predictor for postoperative complications after breast reconstruction, however, study results vary. This retrospective study aimed to investigate the impact of patients’ BMI on postoperative complications following implant-based breast reconstruction. Methods: All implant-based breast reconstructions performed at the Department of Plastic, Reconstructive and Aesthetic Surgery at the Medical University of Vienna from January 2001 to March 2018 were evaluated. A total of 196 reconstructed breasts among 134 patients met eligibility criteria. Demographic data, surgical techniques, as well as major and minor complications within a one-year follow-up period were analyzed. Results: Patients’ BMI did not show a significant impact on complication rates. The overall incidence of postoperative complications was 30.5% (40/131) of which 17.6% required reoperation. Impaired wound healing (18.3%), seroma (6.1%), hematoma (4.6%), capsular contraction (4.6%) and infection (3.8%) were the most common complications. Conclusion: In our study cohort, BMI was not associated with a significantly higher risk of complications. However, postoperative complications significantly increased with a longer operative time and resulted in an extended length of hospital stay.

Purpose: The aim of this study is to analyze a ten-year single center experience in liver transplantation in Pernambuco - Northeastern region of Brazil. Methods: Data were retrospectively collected from medical records of 302 patients who underwent Orthotopic Liver Transplantation (OLT) between 1998 and 2008 at Oswaldo Cruz University Hospital, Pernambuco – Brazil. We analyzed just the outcomes and survival curve of 195 adult liver transplantation recipients from deceased donor. Results: Data concern liver donor, surgery technical aspects and liver transplantation recipients’ postoperative evolution are presented and discussed. This center has a significant experience in liver transplantation using conventional technique with no venovenous bypass. Efficient management of liver transplantation practice has made it feasible to keep the cold ischemia time within 6-7 hours. Because of the organ shortage, we have used a large amount of extended criteria liver donor. The survival 1-year rata was 76.4%. Conclusion: It is possible to provide a high-quality public medical assistance in an efficient and continuous manner in less developed areas of Brazil.
