Postoperative care in hypospadias. Common practices and evidence available. / Cuidados postoperatorios en el hipospadias. Prácticas habituales y evidencia disponible.

INTRODUCTION: There are many alternatives available regarding postoperative care in hypospadias surgery. The objective of this study was to assess the current care situation in our environment and to review the evidence available for pediatric surgeons who conduct this procedure. MATERIALS AND METHODS: A survey regarding the main aspects of hypospadias postoperative care was created and distributed to pediatric surgeons. In addition, the evidence currently published in this field was reviewed. RESULTS: A total of 46 replies were achieved. 100% of the surgeons leave in place a probe or stent, and more than 80% remove it after 5 or 7 days. 87.8% of the respondents use a double diaper, but only 65.2% discharge patients early in the postoperative period. 60.9% prescribe antibiotic prophylaxis for as long as the probe remains in place, and 34.8% use full-dose antibiotic therapy. DISCUSSION: There was a general consensus regarding urethroplasty guiding and the use of compression dressings among the pediatric surgeons surveyed. However, more discrepancies were found in the use of antibiotic therapy and early discharge. The currently available evidence and international practice suggest using a probe with double diaper and early discharge, with postoperative antibiotics being limited. In the absence of clear evidence for a specific care type, the patient's experience could be used to choose the best postoperative protocol on an individual basis.

INTRODUCCION: Existen numerosas alternativas en lo que respecta a los cuidados postoperatorios en la cirugía de hipospadias. El objetivo de este estudio es evaluar la situación actual de estos cuidados en nuestro medio y revisar la evidencia existente al respecto para cirujanos pediátricos que realizan este tipo de intervenciones. MATERIAL Y METODOS: Hemos elaborado y distribuido una encuesta que recoge los principales puntos en el cuidado postoperatorio del hipospadias dirigida a cirujanos pediátricos. Se ha realizado revisión de la evidencia actual publicada al respecto en la especialidad. RESULTADOS: Hemos obtenido un total de 46 respuestas. El 100% de los cirujanos dejan algún tipo de sonda o stent y más del 80% están de acuerdo en retirarlo tras 5 o 7 días. El 87,8% de los encuestados utiliza el doble pañal, pero solo el 65,2% da alta precoz en el postoperatorio. Un 60,9% pauta profilaxis antibiótica mientras dure el sondaje y un 34,8% antibioterapia a dosis plenas. DISCUSION: Existe consenso general respecto a la tutorización de la uretroplastia y el uso de apósito compresivo entre los cirujanos pediátricos encuestados. Se detectan más discrepancias en el uso de antibioterapia y el alta precoz. La evidencia actual y la práctica a nivel internacional apunta hacia el uso de la sonda a doble pañal con alta precoz y la limitación del uso de antibióticos postoperatorios. En ausencia de clara evidencia que favorezca un tipo de cuidado u otro, la experiencia del paciente podría ser utilizada para elegir el mejor protocolo postoperatorio individualizado.

Intestinal duplication isolated from the digestive tract: an entity to be considered. / Duplicación intestinal aislada respecto al tracto digestivo: una entidad a tener en cuenta.

OBJECTIVES: To review intestinal duplications isolated from the digestive tract. MATERIAL AND METHODS: Description of the 27 isolated intestinal duplication cases published; presentation of a new case. RESULTS: Intestinal duplication isolated from the digestive tract represents an extremely rare malformation. This type of duplication is not in close contact with any segment of the intestinal tract, and it has its own vascular pedicle. Preoperative diagnosis rates are lower than those found in classic duplications. In addition to the potential complications, malformation torsion is also to be considered. CONCLUSIONS: This infrequent variant is to be considered at differential diagnosis. Potential torsion should also be taken into account in order to decide when an asymptomatic patient should undergo surgery.

OBJETIVOS: Revisión de las duplicaciones intestinales aisladas, sin conexión con el tracto digestivo. MATERIAL Y METODOS: Se recopilan los 27 casos de duplicación intestinal aislada publicados hasta el momento y se presenta un nuevo caso. RESULTADOS: Las duplicaciones intestinales aisladas sin conexión con el tracto digestivo representan una variante de la malformación extremadamente rara. Este tipo de duplicaciones no están en contacto íntimo con ningún segmento del tracto intestinal y cuelgan de un pe­dículo vascular propio. Tienen menos tasa de diagnóstico prequirúrgico que las duplicaciones clásicas y a las posibles complicaciones hay que añadir la torsión de la malformación. CONCLUSIONES: Es interesante conocer esta variante infrecuente para considerarla en el diagnóstico diferencial. La posibilidad añadida de torsión debe tenerse en cuenta para decidir el momento de la cirugía en el paciente asintomático.

Technical challenges of endoscopic treatment for vesicoureteral reflux after Cohen reimplantation. / Consideraciones técnicas en el tratamiento endoscópico del reflujo vesicoureteral tras reimplante tipo Cohen.

INTRODUCTION: The range of indications for endoscopic treatment of vesicoureteral reflux opens more and more until including correction of secondary reflux (VUR) after ureteral reimplantation. However these cases suppose a technical challenge due to postoperative changes. The aim of this work is to present our experience on endoscopic treatment for VUR in ureteral units with Cohen reimplantation surgery, with special interest in the technical peculiarities of the procedure. MATERIAL AND METHODS: A retrospective study of cases of secondary VUR after reimplantation surgery treated by subureteral injection. TECHNIQUE: We put the needle perpendicular to submucous tunnel and inject medially to hole forming a wheal on the anterior face that occludes the meatus RESULTS: During the 1993-2016 period 21 injections were performed in 15 ureteral units. The ureteral pathology included primary VUR (4), duplex system with lower pole reflux (4), megaureter (3) and ureterocele (2). Average patient age was 5.7 years old (2-12). Succesful outcome had been got in 10 ureteral units (66.67%), a decrease of VUR grade in 4 (26.67%) and perseverance/no resolution of grade IV VUR in 1 (6.67%) DISCUSSION: The anti-reflux mechanism of reimplantation depends on optimizing the submucosous tunnel. This subgroup of pacients is small and there are few studies, hindering the agreement on the most appropiate technique. CONCLUSION: Endoscopic treatment of secondary reflux after reimplantation surgery is a procedure with certain technical feature, but safe and effective offering an alternative prior to surgical reoperation.

[Laparoscopic pyeloplasty in pediatric patients: our experience]. / Pieloplastia laparoscópica en la edad pediátrica. Nuestra experiencia.

The aim of this essay is to present our initial experience with laparoscopic pyeloplasty and highlight how some specific technical changes allowed us to improve our results. We performed a chart review of the patients that underwent laparoscopic pyeloplasty in our institution. We included patients older than 6 months old with proved stenosis of the ureteropelvic junction. We compared our first patients with the last ones in which we performed laterocolic approach in all left pyeloplasties and included a modification of the technique to place an external ureteric stent. We performed 13 laparoscopic pyeloplasties, 8 male patients and 5 female. There were 3 right pyeloplasties (23%) and 10 left ones (77%). We performed transmesocolic approach in 2 cases (left) and laterocolic approach in 11. Mean surgical time was 184 minutes in the first 8 cases and 142 in the 5 last ones. We had three cases of complications in the first group, two stents migrated to ureter and one postsurgical infection. In the last cases we had a postoperative bleeding. Laparoscopic approach is an effective option for pyeloplasty with similar results to those of the open approach in spite of a longer surgical time. Experience and specific surgical details allow us to reduce complication rate and surgical time.

[Heterotaxy-polysplenia, approach to the esophageal hiatus for Nissen technique]. / Heterotaxia-poliesplenia, abordaje del hiato esofágico para técnica de Nissen.

INTRODUCTION: Heterotaxy is a failure in embryonic development to achieve left-right symmetry. OBJECTIVE: To report a case of heterotaxy and show a surgical approach for fundoplication. MATERIAL AND METHODS: A girl with heterotaxy-polysplenia syndrome with gastroesophageal reflux and recurrent abdominal pain. It was decided to perform laparoscopic antireflux treatment with Nissen fundoplication with approach by the right side of the diaphragmatic hiatus and pillars. CONCLUSIONS: Surgery is being discussed in these syndromes, indicating only in cases of recurrent abdominal pain, subocclusive lesions or when diagnosis of gastroesophageal reflux is done. The dilemma is between laparoscopic or classical laparotomy. The main difficulty of the laparoscopic approach is the enlarged liver and stomach placement right despite the esophageal hiatus is normally on the left side.
