Management Strategy of a Grade-3 Cerebrospinal Fluid Leak Repair Following Endoscopic Endonasal Transsphenoidal Excision of Pituitary Macroadenoma.

A skull- base defect with grade-3 cerebrospinal fluid (CSF) leak following a pituitary macroadenoma removal is rare and challenging. We provide a simple sample model of multilayer closure with naturally available hard and soft tissue components. Tamponade was provided to the reconstructed site with a simple inflated Foley's catheter bulb. There was no repair failure and cavities were well mucosalised on follow-up. Mucosal and turbinate preservation was fully achieved in this method as no turbinate flaps were raised or large raw surface exposure was there.

Chondrosarcoma of the Sternum: Surgical Challenges, Chest Wall Reconstruction, and Postoperative Management.

Although rare, primary chondrosarcoma is the most frequent malignant tumor of the sternum. It commonly manifests as a painful, expanding mass arising from the costochondrosternal junction. Since it is resistant to radiotherapy and chemotherapy, surgical resection with reconstruction is the preferred treatment. A 50-year-old male presented with swelling over the left fourth sternocostal joint, gradually increasing in size. Imaging and clinical assessment suggested an infiltrative neoplasm, and surgical resection was indicated. The patient underwent a partial sternectomy, including a resection of the xiphoid process and costal cartilages two to seven and a partial resection of the manubrium. Postoperative pathohistological analysis specified the change as a low-grade chondrosarcoma in the pT1 stage. Chest wall reconstruction involved three pectus bars fixated around the ribs and the placement of a synthetic polypropylene mesh. The patient required postoperative rehospitalization due to partial skin layer wound dehiscence, serous drainage, and fever. Empirical antibiotic therapy was initiated, and the patient underwent a median superior laparotomy with partial omentoplasty of the sternal region, preserving the mesh and pectus bars. A culture analysis revealed methicillin-resistant Staphylococcus epidermidis, and postoperative antibiotic therapy was adapted to the antibiogram. Subsequently, all parameters of inflammation decreased, and wound healing followed. A one-year follow-up CT scan showed no disease recurrence. This case highlights the intricate surgical management that contributed to the successful treatment of sternal chondrosarcoma. Sternal wound infection, a severe postoperative complication with a high mortality rate, requires prompt identification, precise revision with culture-directed antibiotics, and effort to preserve the prosthetic material.

Reconstruction of Craniomaxillofacial Bone Defects with 3D-Printed Bioceramic Implants: Scoping Review and Clinical Case Series.

Reconstruction of craniomaxillofacial bone defects using 3D-printed hydroxyapatite (HA) bioceramic patient-specific implants (PSIs) is a new technique with great potential. This study aimed to investigate the advantages, disadvantages, and clinical outcomes of these implants in craniomaxillofacial surgeries. The PubMed and Embase databases were searched for patients with craniomaxillofacial bone defects treated with bioceramic PSIs. Clinical outcomes such as biocompatibility, biomechanical properties, and aesthetics were evaluated and compared to those of commonly used titanium or poly-ether-ether-ketone (PEEK) implants and autologous bone grafts. Two clinical cases are presented to illustrate the surgical procedure and clinical outcomes of HA bioceramic PSIs. Literature review showed better a biocompatibility of HA PSIs than titanium and PEEK. The initial biomechanical properties were inferior to those of autologous bone grafts, PEEK, and titanium but improved when integrated. Satisfactory aesthetic results were found in our two clinical cases with good stability and absence of bone resorption or infection. Radiological signs of osteogenesis were observed in the two clinical cases six months postoperatively. HA bioceramic PSIs have excellent biocompatible properties and imitate natural bone biomechanically and radiologically. They are a well-suited alternative for conventional biomaterials in the reconstruction of load-sharing bone defects in the craniomaxillofacial region.

Multi-Institutional Bladder Exstrophy Consortium After 8 Years: The Short- and Intermediate-Term Outcomes.

PURPOSE: Bladder exstrophy (BE) poses challenges both during the surgical repair and throughout follow-up. In 2013, a multi-institutional BE consortium was initiated, which included utilization of unified surgical principles for the complete primary repair of exstrophy (CPRE), real-time coaching, ongoing video capture and review of video footage, prospective data collection, and routine patient data analysis, with the goal of optimizing the surgical procedure to minimize devastating complications such as glans ischemia and bladder dehiscence while maximizing the rate of volitional voiding with continence and long-term protection of the upper tracts. This study reports on our short-term complications and intermediate-term continence outcomes. MATERIALS AND METHODS: A single prospective database for all patients undergoing surgery with a BE epispadias complex diagnosis at 3 institutions since February 2013 was used. For this study, data for children with a diagnosis of classic BE who underwent primary CPRE from February 2013 to February 2021 were collected. Data recorded included sex, age at CPRE, adjunct surgeries including ureteral reimplantations and hernia repairs at the time of CPRE, osteotomies, and immobilization techniques, and subsequent surgeries. Data on short-term postoperative outcomes, defined as those occurring within the first 90 days after surgery, were abstracted. In addition, intermediate-term outcomes were obtained for patients operated on between February 2013 and February 2017 to maintain a minimum follow-up of 4 years. Outcomes included upper tract dilation on renal and bladder ultrasound, presence of vesicoureteral reflux, cortical defects on nuclear scintigraphy, and continence status. Bladder emptying was assessed with respect to spontaneous voiding ability, need for clean intermittent catheterization, and duration of dry intervals. All operating room encounters that occurred subsequent to initial CPRE were recorded. RESULTS: CPRE was performed in 92 classic BE patients in the first 8 years of the collaboration (62 boys), including 46 (29 boys) during the first 4 years. In the complete cohort, the median (interquartile range) age at CPRE was 79 (50.3) days. Bilateral iliac osteotomies were performed in 89 (97%) patients (42 anterior and 47 posterior). Of those undergoing osteotomies 84 were immobilized in a spica cast (including the 3 patients who did not have an osteotomy), 6 in modified Bryant's traction, and 2 in external fixation with Buck's traction. Sixteen (17%) patients underwent bilateral ureteral reimplantations at the time of CPRE. Nineteen (21%) underwent hernia repair at the time of CPRE, 6 of which were associated with orchiopexy. Short-term complications within 90 days occurred in 31 (34%), and there were 13 subsequent surgeries within the first 90 days. Intermediate-term outcomes were available for 40 of the 46 patients, who have between 4 and 8 years of follow-up, at a median of 5.7 year old. Thirty-three patients void volitionally, with variable dry intervals. CONCLUSIONS: Cumulative efforts of prospective data collection have provided granular data for evaluation. Short-term outcomes demonstrate no devastating complications, that is, penile injury or bladder dehiscence, but there were other significant complications requiring further surgeries. Intermediate-term data show that boys in particular show encouraging spontaneous voiding and continence status post CPRE, while girls have required modification of the surgical technique over time to address concerns with urinary retention. Overall, 40% of children with at least 4 years of follow-up are voiding with dry intervals of > 1 hour.

Análise epidemiológica das fraturas de mão em um hospital terciário / Epidemiological analysis of hand fractures in a tertiary hospital

Introdução: O trauma de mão constitui uma epidemia, ocorrendo por diversos fatores, como acidentes de trabalho e violência urbana. Isso gera um impacto significativo por ser uma unidade anatômica vulnerável e importante na realização de atividades cotidianas e para o trabalho. Desse modo, faz-se necessária uma avaliação epidemiológica mais aprofundada no que tange, sobretudo, às fraturas de mãos, entendendo sua elevada morbidade. Método: Estudo descritivo e retrospectivo, feito por análise de prontuários de pacientes conduzidos em um hospital terciário no período de janeiro de 2018 a dezembro de 2020. Resultados: Participaram do estudo 290 pacientes, sendo 85,7% do sexo masculino e 14,3% do sexo feminino. 138 indivíduos tinham entre 20 e 39 anos, representando um total de 47,6%. 51,6% eram do interior do estado do Ceará e 48,4% eram da capital. O principal mecanismo de trauma associado às fraturas foram os acidentes de trânsito (36,4%), seguidos por acidentes de trabalho (26,9%) e ferimentos por arma de fogo (14%). Em relação aos ossos fraturados, houve uma acentuada prevalência do acometimento das falangeanas, em todas as faixas etárias, representando 210 pacientes (72,4%). Conclusão: O presente estudo corrobora com os dados presentes na literatura. Desse modo, é evidenciada a repetição de prevalência de faixa etária, principais mecanismos de trauma envolvidos, bem como ossos acometidos nas fraturas de mão.

Introduction: Hand trauma is an epidemic occurring due to several factors, such as work accidents and urban violence. This significantly impacts it as it is a vulnerable and important anatomical unit for daily activities and work. Therefore, a more in-depth epidemiological assessment is necessary regarding hand fractures and understanding their high morbidity. Method: A descriptive and retrospective study was conducted by analyzing the medical records of patients treated in a tertiary hospital from January 2018 to December 2020. Results: 290 patients participated in the study, 85.7% male and 14.3 % female. One hundred thirty-eight individuals were between 20 and 39 years old, representing 47.6%. 51.6% were from the interior of the state of Ceará, and 48.4% were from the capital. The main trauma mechanism associated with fractures was traffic accidents (36.4%), followed by work accidents (26.9%) and firearm injuries (14%). Concerning fractured bones, there was a marked prevalence of phalangeal involvement in all age groups, representing 210 patients (72.4%). Conclusion: The present study corroborates the data present in the literature. In this way, the repetition of the prevalence of age group, main trauma mechanisms involved, as well as bones affected by hand fractures is evidenced.

Cost-effective Solution for Maxillofacial Reconstruction Surgery with Virtual Surgical Planning and 3D Printed Cutting Guides Reduces Operative Time.

Background: This study aimed to explore a low-cost solution for virtual surgical planning/3D printed surgical guides in a training hospital, assessing the impact on intraoperative time and bleeding. Material and Methods: We included a total of 13 patients. 8 who underwent maxillofacial reconstruction surgery with fibula-free flap utilizing virtual surgical planning/3D printed guides (VP/SG), and 5 using conventional surgery (CS) from 2017 to 2020. The surgical time, bleeding, length of hospital stay, and comorbidities were collected and compared in two groups. We recorded the average cost for the complete surgical planning and 3D printed guides. We applied a qualitative survey to the surgeons involved in the surgical procedures. Results The mean surgical time in the VP/SG group was 8.16 ± 2.7, compared to the CS group 12.5 ± 3.8, showing a 4.34 hours difference with statistical significance (p = 0.033). Patients from the CS group had a higher bleeding volume of 921 ± 467.6 mL VS 760 ± 633.8 mL in the VP/SG group. The average cost for the complete surgical planning and 3D printed guides was 914.44 ± 46.39 USD. All the surgeons who answered the survey preferred to perform the procedure utilizing the virtual planning/3D printed guides. Conclusions Virtual planning and 3D printed surgical guides have the potential to reduce operation time in maxillofacial reconstruction.

Des patients du groupe CS ont perdu un plus grand volume de sang que les patients du groupe VP/SG (respectivement, 921 ± 467.6 mL contre 760 ± 633.8 mL). Le coût moyen de la planification chirurgicale complète et des guides imprimés en 3D a été de 914,44 ± 46,39 US$. Tous les chirurgiens ayant répondu à l'enquête ont préféré utiliser la planification virtuelle/les guides imprimés en 3D pour la réalisation de la procédure. Conclusions : La planification virtuelle et les guides chirurgicaux imprimés en 3D ont le potentiel de réduire les temps opératoires pour la reconstruction maxillo-faciale.

Hand Reconstruction Using Anterolateral Thigh Free Flap by Terminal Perforator-to-Digital Artery Anastomosis: Retrospective Analysis.

This study aimed to analyze cases of anterolateral thigh (ALT) free flap used for hand reconstruction with terminal perforator-to-digital artery anastomosis. Patients who underwent ALT free flap placement with terminal perforator-to-digital artery anastomosis for hand reconstruction between January 2011 and August 2021 were included. The number, length, and diameter of the perforators and veins, flap size, and operative time were investigated through a retrospective review of charts and photographs. The occurrences of arterial thrombosis, venous thrombosis, arterial spasm, and flap necrosis were analyzed. In total, 50 patients were included in this study. The mean diameter and length of the perforators were 0.68 mm and 3.25 cm, respectively, and the mean number of veins anastomosed was 1.88, with a mean diameter of 0.54 mm. Complications included four cases of arterial thrombosis, one case of venous thrombosis, seven cases of partial necrosis, and one case of total flap failure. Regression analysis showed that a longer perforator was associated with arterial thrombosis whereas larger flap size and number of anastomosed veins were associated with partial necrosis ( p < 0.05). The terminal perforator-to-digital artery anastomosis offers advantages in using compact free flaps with short pedicle lengths to cover small hand defects.

Mandibular Myxoid Liposarcoma: a Case Study.

Liposarcomas are described as soft tissue sarcomas derived from adipose tissue. The finding of this tumor in the mandibular region is exceedingly rare. As of now, it has been described mainly in case reports and small series. A multidisciplinary approach is required to offer optimal treatment and may involve surgery, radiation and systemic therapies. Surgical repair of these defects represents a major challenge in oral and maxillofacial reconstructive surgery. We present the case of a 54-year-old man referred to our center with a progressively increasing mass in the anterior portion of the mandible. Biopsy revealed a well-differentiated myxoid liposarcoma. Resection of the tumor was performed with an additional primary reconstruction.

[Posterolateral instability of the knee joint]. / Posterolaterale Instabilität des Kniegelenks.

The posterolateral corner of the knee is composed of a multilayered complex of ligamentous, musculotendinous, and capsular structures, which interact in a synergistic stabilizing manner with the central structures, particularly the posterior cruciate ligament. Injuries of the posterolateral corner are generally accompanied by rupture of the posterior cruciate ligament. Depending on the injured structures, injuries of the posterolateral corner result in posterolateral rotational instability alone (Fanelli A) or with lateral instability (Fanelli B/C). For rotational instability alone, isolated popliteus bypass is an effective procedure; with concomitant lateral instability in flexion, additional stabilization of the lateral collateral ligament is required. Most of the various available techniques are described as open reconstruction procedures. In recent years, arthroscopic techniques for posterolateral reconstruction have also been successfully developed.

Male epispadias repair: Outcomes at three sites prior to the establishment of a multi-institutional collaboration.

INTRODUCTION: Epispadias, which occurs on the more mild end of the Bladder Exstrophy Epispadias Complex (BEEC) spectrum, presents still with a wide range of severity in boys, from mild glanular epispadias to penopubic epispadias with severe urethral and bladder neck defects. Surgical management ranges from isolated epispadias repair to epispadias repair with bladder neck reconstruction (BNR) with or without pelvic osteotomies. OBJECTIVES: We aimed to evaluate outcomes in epispadias treated at three institutions prior to formation of a formal collaboration. In addition, we sought to delineate outcomes based on anatomic severity at time of diagnosis, and initial procedure performed in cases of penopubic epispadias. METHODS: IRB approved databases were retrospectively queried at three institutions for patients who underwent repair of epispadias between 1/1993 and 1/2013. Degree of epispadias, age and technique at initial repair, and self-reported continence status at last follow-up were recorded. Continence was categorized as: wet, intermediate (dry 2-3 h), or dry, while also distinguishing those who void and those who require clean intermittent catheterization (CIC). Those not seen since 1/1/2015, younger than 10 years at last follow up, or in whom continence data were not recorded were excluded. RESULTS: A total of 48 boys were identified; 36 met inclusion criteria. The epispadias cohort consisted of 8 glanular epispadias (GE) (22%); 8 penile epispadias (PE) (22%), and 20 penopubic epispadias (PPE) (56%) with a median follow-up of 11.3 years (3.2-26.2 years). Overall, 33 of 36 (92%) boys void per urethra. Within the group that voids, 19/33 (58%) are completely dry, while 6/33 (18%) are wet. Among patients who underwent initial epispadias repair without concurrent or subsequent bladder neck reconstruction, continence rates were: GE 63% (5/8); PE 75% (6/8); PPE 71% (5/7). Among the 9 boys with PPE who underwent initial epispadias repair with concurrent BNR, 22% (2/9) were dry with no further surgeries. Overall, 8/20 (40%) of boys with PPE void with complete dryness. DISCUSSION: This multi-center retrospective review of continence in epispadias demonstrates that even some boys with glanular and penile epispadias can have challenges with continence, and boys with penopubic epispadias may remain wet despite careful preoperative assessment of bladder neck functionality and concurrent BNR. CONCLUSION: Continence outcomes in boys with all degrees of epispadias can be variable. Even boys with more distal defects may have significant bladder neck deficiency. And those with the most severe form of epispadias may require bladder neck reconstruction to achieve continence.

Robot-assisted ureteric reconstructive surgeries for benign diseases: Initial single-center experience with point of technique.

INTRODUCTION: We present our initial experience with robot-assisted reconstructive surgeries with the Da Vinci Xi robotic system for benign ureteric pathologies. MATERIALS AND METHODS: This is a retrospective review of prospectively collected data of patients who underwent robot-assisted reconstructive procedures for benign diseases of the ureter at our department from April 2018 to November 2022. Demographic and perioperative details were recorded. Patients were followed up and surgical success was evaluated on the basis of symptomatic, functional, and radiological improvement. RESULTS: A total of 34 patients underwent robot-assisted reconstructions for benign ureteric pathologies by various techniques. Mean age, body mass index (BMI), hospital stay and follow-up duration were 36 years, 24.1 kg/m2, 5.29 days, and 7.08 months respectively. Procedures included pyeloplasty in eight, primary ureteroneocystostomy (UNC) in seven, Psoas hitch UNC in five, Boari flap UNC in six, Ureteroureterostomy in four, ureterocalicostomy in two and ileal ureteral transposition in two patients. Mean docking time, total operative time, and estimated blood loss were 31.5 min, 178 min, and 64.3 ml, respectively. All patients had radiologic or functional improvement on follow-up after 6 months. CONCLUSION: Robot-assisted reconstructive surgery for benign ureteric and bladder pathologies imparted excellent short-term outcomes without major complications with all the advantages of a minimally invasive approach.

Usefulness of external fixation and reverse Sural fasciocutaneous flap: Treatment of grade III B open tibial fractures in resource-limited settings.

PURPOSE: Sierra Leone is a low-income country located on the west coast of Africa where the majority of the population does not have free access to emergency medical and surgical services, the principal cause of open tibia fractures is motorcycle collision. Open fractures of the middle and distal third of the tibial segments, particularly those classified as type III B, represent a challenge for orthopedic surgeons because of the loss of soft tissue coverage. The Reverse Sural Fasciocutaneous Flap (RSFF) has been shown to be an ideal and reproducible option for the treatment of soft tissue defects. The main aim of this study was to demonstrate the experience in Resource Limited Settings (RLS) by means of a short series of the efficacy of using a combination of external fixation and RSFF in the treatment of grade III B open tibia fractures where plastic surgeons were not available. METHODS: This retrospective, descriptive, and non-experimental study included 8 patients who underwent surgical intervention between September 2020 and September 2021. RESULTS: The skin defects were of various sizes; the smallest size was 4 × 7 cm, and the biggest size of 12 × 18 cm. We obtained a success rate in seven of the eight cases. CONCLUSIONS: External fixation and reverse sural fasciocutaneous sural flap are excellent therapeutic options for the treatment of open grade III B diaphyseal and metaphyseal distal tibial fractures.

Advancing Intraoperative Assessment of Urethral Stricture Anatomic Variation: A Prospective Proof-of-Concept Study.

INTRODUCTION: Urethral strictures, particularly those refractory to endoscopic interventions, are commonly treated through open urethroplasty. However, predicting recurrence in homogeneous patient populations remains challenging. METHODS: To address this, we developed an intraoperative urethral stricture assessment tool aiming to identify comprehensive risk predictors. The assessment includes detailed parameters on stricture location, length, urethral bed width, spongiosum thickness, obliteration grade, and spongiofibrosis extension. The tool was prospectively implemented in 106 men with anterior one-stage augmentation urethroplasty from April 2020 to October 2021. RESULTS: An intraoperative granular assessment of intricate stricture characteristics is feasible. Comparative analyses revealed significant differences between bulbar and penile strictures. Bulbar strictures exhibited wider urethral beds and thicker spongiosum compared to penile strictures (all p < 0.001). The assessment showed marked variations in the degree of obliteration and spongiofibrosis extension. CONCLUSION: Our tool aligns with efforts to standardize urethral surgery, providing insights into subtle disease intricacies and enabling comparisons between institutions. Notably, intraoperative assessment may surpass the limitations of preoperative imaging, emphasizing the necessity of intraoperative evaluation. While limitations include a single-institution study and limited sample size, future research aims to refine this tool and determine its impact on treatment strategies, potentially improving long-term outcomes for urethral strictures.

Maxillary and total nasal reconstruction with a scapulo dorsal perforator flap.

Facial gunshots injuries remain challenging and present functional and aesthetic problems. Such defects generally require composite tissue flaps for reconstruction. Rebuilding the palate and the maxilla is especially delicate because it requires reconstitution of the facial buttresses, and replacement of bony hard palate, based on occlusion, as well as the restoration of the thin intraoral and intranasal lining which normally constitute the soft palate. Various methods of reconstruction have been applied to this area in search of an ideal soft tissue and bone flap to restore the bony framework of the maxilla and palate while providing an internal lining. The scapula dorsal perforator flap is used in the case of a patient to successfully reconstruct the palate, the maxilla and the nasal pyramid in one stage. Free tissue transfer using thoracodorsal perforator flaps and scapula bone free flap have been already described in literature but never to perform the nasal pyramid reconstruction at the same time. Good functional and aesthetic results have been obtained in this case. This article also reviews, through the authors experience and literature, anatomical landmarks, indications, technical surgical tricks, advantages and disadvantages of this flap for palatal, maxillary and nose reconstruction.

In situ shell technique for edentulous ridge augmentation.

BACKGROUND: The novel two-stage technique presented in this study is based on guided bone regeneration for three-dimensional bone augmentation. METHODS AND RESULTS: The proposed technique was performed to augment an atrophic alveolar ridge in the maxilla and mandible. This method is based on using an autogenous bone plate, a mixture of allogeneic bone graft and injectable -platelet-rich fibrin, and a bioresorbable barrier membrane. Based on the cases presented in this study, sufficient osseous regeneration was achieved to place dental implants in an ideal position. CONCLUSION: Within the limitations of the present study, it seems that in situ shell technique could be a beneficial method to augment the extremely atrophied ridges with less morbidity and shorter operative time. KEY POINTS: Why is this case new information? The cases presented a new technique using in situ autogenous plates for ridge augmentation. What are the keys to the successful management of this case? The keys to the successful management of these cases are proper flap management and less traumatic bony plate preparation. What are the primary limitations to success in this case? The primary limitation to success in this technique would be a need for high surgical skills to conduct the procedure accurately.

Autoimmune Autoinflammatory Syndrome Induced by Adjuvants (ASIA) After Injection of Foreign Materials for Cosmetic Purposes: Retrospective Analysis of 1027 Cases.

BACKGROUND: The injection of illicit, non-regulated foreign materials may trigger an autoimmune autoinflammatory syndrome induced by adjuvants (ASIA). METHODS: A retrospective review of health records was performed to identify patients' epidemiological and clinical characteristics. The issues analyzed were age and gender of cases, occupation, the person who administered the substance, anatomical site, type and volume of the injected substance, time from injection to the onset of symptoms, chief complaint, measures taken to alleviate symptoms, local complications, systemic manifestations, and imaging method to aid in diagnosis. RESULTS: More than 70% of patients were female and dedicated to household activities; the mean age was 44 years for females and 40.7 years for males. One-quarter of patients reported some comorbidity. The most commonly reported substance was mineral oil, whereas the most frequent anatomical site was the gluteal region with volumes around one liter. Signs and symptoms occurred almost exclusively at a local level, pain (40%) and swelling (18%) being the predominant manifestations with a peak incidence after three years. Treatment was mainly medical; surgery, primarily en bloc resection, was performed in 20% of patients. CONCLUSIONS: A myriad of substances may induce autoimmune autoinflammatory syndrome induced by adjuvants (ASIA) when injected for cosmetic purposes. Since effective treatments are scarce, public policies should be enforced to alert the community and limit the consequences of this healthcare problem.

Long-Term Bowel Vaginoplasty With a Single Yang-Monti Tube.

INTRODUCTION: The bowel remains the favored tissue for neo-vaginoplasty (NeoVP) in pediatric patients with vaginal agenesis. In 2001, the first description of NeoVP using the Yang-Monti technique with a sigmoid double tubular flap was published. We present our experience of NeoVP with a single Yang-Monti tube (SYMT) flap and report on the use of different segments of colon. METHODS: We conducted a retrospective review of patients who underwent NeoVP using a bowel SYMT between 2009 and 2021. The procedure was performed under open abdominal surgery by isolating 8 to 12 cm from the rectosigmoid, cecum, or ascending colon. Subsequently, this segment was detubularized near the mesenteric border, folded, and retubularized transversally, leaving the mesentery in a cephalic position. A channel was dissected in the pelvis to accommodate the NeoVP. RESULTS: Seventeen patients were identified. The median age was 16 years old. The principal diagnosis was Mayer-Rokitansky's syndrome (47.1%). The median follow-up was 50 months. The mean harvested bowel length was 9 cm, and the sigmoid was the preferred site (65%). The cecum-ascending colon was used in 3 (17.6%) patients. Complications were recorded in 6 patients (35%). Of these 6 patients, 4 had introital stenosis. There was 1 case of urethrovaginal fistula and another of left hematometrocolpos. Satisfactory sexual function has been reported in sexually active individuals. CONCLUSIONS: We described our experience in NeoVP using a large bowel SYMT as a safe and effective technique. It allows decreased tension on the vascular pedicle and the use of shorter colon segments.
