[PEG versus LAP: towards a safer technique for long-term enteral nutrition]. / PEG versus LAP: hacia una técnica más segura para la nutrición enteral a largo plazo.

OBJECTIVE: To compare the outcomes and complications between laparoscopic gastrostomies (LG) and percutaneous endoscopic gastrostomies (PEG). METHODS: Retrospective review of 79 patients who had their gastrostomies inserted in our hospital (2010-2017). We compared surgical techniques, minor and major complications. RESULTS: A total of 24 LG (14 males) and 55 PEG (29 males) were performed. The mean age was 4.77 [0.15-15.56] years for LG and 5.37 [0.12-16.58] years for PEG. The median time of presentation of complications was 59 [2-975] days. No statistical differences were found in minor complications between both techniques; however, minor complications were more frequent in LG (54.16% in LG versus 34.55% in PEG), mainly, overgranulation and peristomal leakage. A statistically significant association was found between patients with oncological comorbidity and minor complications (p<0.05).A statistically significant association was found between major complications and PEG (4.17% in LG versus 21.82% in PEG), p=0.045. The major complications were one tube dislodgement in the LG group, and 9 Buried-Bumper syndrome, one colon interposition without perforation, one colon perforation, one omentum interposition, two tube dislodgements and one small bowel perforation in PEG group. CONCLUSIONS: Given the statistically significant association between major complications and the PEG group, being the higher frequency and severity of these complications with this technique evident; we consider the LG a safer technique. However, studies with larger number of patients and multicentric are necessary.

OBJETIVO: Comparar los resultados y las complicaciones de las gastrostomías laparoscópicas (LAP) frente a las gastrostomías endoscópicas percutáneas (PEG). MATERIAL Y METODO: Estudio retrospectivo de 79 pacientes intervenidos quirúrgicamente para la realización de una gastrostomía en nuestro centro (2010-2017). Comparamos las complicaciones menores y mayores entre ambas técnicas. RESULTADOS: Realizamos 24 LAP (14 varones) y 55 PEG (29 varones). La edad media fue de 4,77 [0,15-15,56] años en las LAP y 5,37 [0,12-16,58] años en las PEG. La mediana del tiempo de presentación de las complicaciones fue de 59 [2-975] días. No se encontraron diferencias significativas en las complicaciones menores entre ambas técnicas, sin embargo, son más frecuentes en las LAP (5,16% en LAP frente a 34,55% en PEG), siendo principalmente granulomas y fugas perigastrostomías. Encontramos asociación estadísticamente significativa entre pacientes con comorbilidad oncológica y la aparición de complicaciones menores (p<0,05), así como una asociación estadísticamente significativa entre las PEG y las complicaciones mayores (4,17% en LAP frente a 21,82% en PEG), con p=0,045. Las complicaciones mayores fueron, en las LAP un descolgamiento y en las PEG 9 síndrome de Buried-Bumper, un atrapamiento de colon sin perforación, una perforación de colon, un atrapamiento de epiplón, dos descolgamientos y una perforación de intestino delgado. CONCLUSIONES: Dada la asociación existente entre las complicaciones mayores y el grupo PEG, siendo evidente la mayor frecuencia y gravedad de estas complicaciones con esta técnica, consideramos la LAP una técnica más segura. Sin embargo, son necesarios estudios con un mayor tamaño muestral y, a ser posible, multicéntrico.

[What can we do to improve our management of intestinal atresia?]. / ¿Qué podemos mejorar en el tratamiento de las atresias intestinales?

OBJECTIVE: To review our management of intestinal atresia (AI). MATERIAL AND METHODS: A retrospective review of patientes with AI, from 1995 to 2011. RESULTS: AI was identified in 41 patients, 29,2% had maternal polyhydramnios and 48,7% were diagnosed prenatally. Four of them had Down Syndrome and 18 had cardiopathy. Duodenal atresia-stenosis (AD) was present in 21 patients, that were treated by 19 duodenoduodenostomy, 1 duodenojejunostomy and 1 duodenotomy with duodenal membrane resection. Jejunoileal atresia (AYI) was present in 20 patients and we performed 15 end to end anastomosis, 1 íleo-colic anastomosis, 1 ileostomy, 2 jejunostomies and 1 end to end anastomosis with jejunostomy. Nine AYI were reoperated: 6 bowel obstructions, 1 evisceration and 2 colo-rectal atresia. The average time on parenteral nutrition was 29 days and average hospital stay was 37,3 days. One AD died due to heart disease. In AYI, 2 required transfer to another center due to short bowel. CONCLUSIONS: Prenatal diagnosis of AI is difficult, especially AYI, which is only prenatally diagnosed in 35% of cases. AD respond better to surgery and rarely require reoperation, but mortality is higher than AYI because 57% suffer from heart disease. Reoperations are frecuent in AYI (45% of our patients), usually due to obstruction, ostomy closure and problems resulting from extensive bowel resections. It's important to keep in mind colorectal atresias, which can not be identified.

[Our experience with the use of alpha-lithic therapy in the treatment of voiding dysfunction]. / Nuestra experiencia con el uso de alfa-líticos en el tratamiento de la disfunción de vaciado.

INTRODUCTION: Dysfunctional voiding (DV) is due to a dysfunction in the pelvis floor muscles caused by hyperactivity of the urethral sphincter and the musculature of this zone during the voiding phase of the micturition cycle. The treatments used are recommending correct micturition habits, biofeedback and pelvic relaxation exercises. Currently, drugs are also used, such as alpha lithic drugs and injection of botulinic toxin, however its experience in children is limited. OBJECTIVES: Show our experience with the use of alpha-lithics in patients with DV. MATERIAL AND METHODS: Review of patients with DV treated with alpha-lithics in our institution. RESULTS: 6 patients with DV were treated with alpha-lithics (Alfuzosin or Doxazosin). Girl (12 years) with Wolfram Syndrome with significant post-void residual urine, who initially rejected intermittent catéter. Residual urine decreases slightly with treatment, but isn't enough. Boy (7 years) with uretral duplicity and difficulty urine flow without observable stenosis. He had initial improvement but then required continent bladder diversión and vasectomy due to recurrent orchiepididymitis. Boy (5 years) with ureteral-bladder stenosis and ureteral reimplantation with urinary tract infection and vesico-ureteral reflux that did not improve (an anatomic obstruction was subsequently found). Boy (12 years) with tethered cord and pyelonephritis, who rejected intermittent catheter. He hadn't improvement and he required continent bladder diversión. Boy (7 years) with Syringomyelia, operated in another center for vesico-ureteral reflux with ureteral reimplantation, with recurrent urine infections, who hadn't improvement and required continent bladder diversion. Boy (10 years) with resected urethra valves and normal cystoscopy, with episodes of urine retention, without improvement with treatment. CONCLUSION: The role of alpha-lithics in the treatment of dysfunctional voiding in children is limited and of doubtful efficacy. It may be useful in patients with significant post-micturition residue.

[Cystic dilation of the bile duct in childhood]. / Dilatación quística de la vía biliar en la infancia.

OBJECTIVES: Common bile duct dilatation (CBDD) represents part of a wide spectrum of pancreaticobiliary disorders, with different etiopathogenic mechanisms. The objective of this study was to compile the cases treated in our service during the last five years. PATIENTS AND METHODS: Four cases of CBDD (17 months to 10 years of age) are reported. All of them presented abdominal pain and bilious vomiting. One patient previously had pancreatitis. Cholestatic jaundice was associated in only one patient. The diagnosis was made by ultrasound, being confirmed by endoscopic retrograde cholangiopancreatography (ERCP) in three cases and by computed tomography scan (CT) in one case. RESULTS: Three patients had a single fusiform dilation of the extrahepatic bile duct (type I cyst, Alonso Lej-Todani classification), which were treated by cyst excision and hepaticojejunostomy by using a Roux-en-Y limb. In one patient, the ERCP detected a combined dilatation of the intra- and extrahepatic bile duct (type IV cyst), associated with an anomalous choledochopancreticoductal junction with a distal obstruction of the common bile duct. In the case, the treatment consisted of a transduodenal esfintherotomy. CONCLUSIONS: Based on our experience and a literature review, an increasing incidence of this pathology is deduce. Therefore, the relevance of ultrasounds and ERCP in the diagnosis and visualization of pancreatobiliary ducts and the choice of treatment, depending on the CBDD, are discussed.

[Clinical and anatomopathologic study of 800 cryptorchid testis]. / Estudio clínico y anatomopatológico de 800 testes criptórquidos.

662 children (800 cryptorchid testes) has been studied in order to check if the age and location were important factors in the degree of the lesion found in the biopsy. We have related in this survey the tubular fertility index (IFT) and tubular diameter (DT) to the age and location of the testes and we have not proved statistically their relationship, for which reason we do not advise to plan the age of surgery in terms of possible anatomopathologic damage.
