Comparative study between isolated intestinal perforation and necrotizing enterocolitis.

INTRODUCTION: Intestinal perforations in the neonatal period are usually related to necrotizing enterocolitis (NEC) or intestinal occlusion. Intestinal perforation in the absence of these conditions is called isolated perforation (IP). Several risk factors and pathogenic mechanisms have been suggested, and most of them are common to those classically attributed to NEC. AIM: To identify and compare the clinical and pathological features of IP and NEC. MATERIAL AND METHODS: We reviewed all cases of neonatal intestinal perforation and NEC in the last five years. Thirty-three patients were retrospectively classified into Group NEC: 24 cases, and Group IP: 9 cases. We collected multiple data as study variables: 1) General features; 2) Obstetric history; 3) Neonatal treatment; 4) Comorbidity; 5) Perforation features; 6) Treatment and outcome. RESULTS: Comparing the groups, we found statistical significant differences in isolated perforation cases with these risk factors: extreme prematurity, very low birth weight, abruptio placenta, intubation and neonatal mechanical ventilation, umbilical catheterization, precocious sepsis, and indomethacin therapy. A more precocious operation and a good prognosis also reached statistical significance. In the other hand, we found statistically significant differences in NEC with congenital cardiopathy (excluding isolated patent ductus arteriosus), with intestinal pneumatosis, with diffuse bowel involvement and a worse prognosis. Risk factors and pathologic findings seem to support an ischaemic pathogenesis in both diseases.

[Continent urinary diversion: the Mitrofanoff principle].

INTRODUCTION: Continent urinary diversion (based on Mitrofanoff's principle), despite its complexity, is the gold standard in the treatment of those vesicourethral disfunctions that need clean intermittent catheterization (CIC) to achieve complete vesical voiding, in patients with non easily catheterizable native urethra. AIM: To analize our experience in continent urinary diversion at our centre. PATIENTS AND METHODS: We have reviewed the records of the 14 cases of continent urinary diversion in the last 8 years. They were grouped in order to the underliying condition: 1-Bladder exstrophy group (n=5): Mean age at diversion time was 5.5 years (range 3-7). In all patients the original Mitrofanoff s technique was performed (continent cutaneous appendicovesicostomy). Associated procedures were: ureterovesical reimplantation in all 5 cases; bladder neck reconstruction also in all 5 (3 of them needed vesicourethral transection); and bladder augmentation in two cases, using ileum and sigmoid respectively. 2- Myelomeningocele group (n=9, 10 procedures): Mean age was 11.5 years (range 6-16). Appendicovesicostomy was performed in 7 cases and a reconfigured ileum with the Casale technique was used in 3 cases (primarily in 2 and as an alternative in one). Associated procedures were: ureterovesical reimplantetion in 5 cases and bladder augmentation in 7 (using sigmoid in 4, ileum in 2 and urether in one case). RESULTS: In all patients complete continence was achieved. Complications found were: one appendicostomy prolapse, one appendix necrosis (that was then diverted with Casale's technique), one appendicular conduit stenosis and one case with catheterization difficulties that needed a tappering of the ileum conduit. Nowadays, 13 out of 14 pacients follow the CIC program each 3-4 hours without complication. CONCLUSION: Continent urinary diversion improves autonomy and life quality in those patients that need a definitive urinary diversion and have a long life expectancy. We have used these procedure with good results in patients with severe vesicourethral disfunction (of an intrinsic or neuropathic origin) in which clean intermittent catheterization was not possible through native urethra, or in patients with refractary incontinence in which vesicourethral transection was the only effective treatment.

[Laparoscopic adrenalectomy].

BACKGROUND/PURPOSE: Laparoscopic adrenalectomy is a standard procedure in adult patients. In the pediatric patient the same advantages with regard to traditional surgery have been demonstrated in the treatment of localized adrenal tumours. The aim of this work is to analyze our initial experience in this technique. MATERIAL AND METHODS: We have reviewed our last three adrenalectomy cases. They were two girl and a boy aged 4, 15 and 17 year-old. The etiology was pheochromocytoma in two cases and one ganglioneuroblastoma. In two cases the tumour was right-sided and the other one was in the left adrenal gland. All cases were studied with ultrasound, TC and MRI. Patients with pheochromocytoma were also studied with MIBG-scintigraphy and genetics, hormone and endocrine MEN screening. One patient with pheochromocytoma had von Hippel-Lindau disease. Main size tumour was 40 mm. Preoperative alpha-blockade in pheochromocytoma was done with prazosín and intraoperative with nitroprusside. In lateral decubitus position, through four 10 and 5 mm ports, in two cases adrenalectomy was performed and tumorectomy in one. RESULTS: Main operating time was 120 minutes. There was no operative-related complication. Blood pressure in pheochromocytoma patients was controlled without drugs 36h after surgery. They were discharged between the 2nd and 4th postoperative day. No incidences on follow-up. CONCLUSIONS: Adrenalectomy joins other pediatric procedures affordable with the laparoscopic approach. It minimizes surgical trauma, gland exposure is better, allows a safe and quick resection in adrenal tumours, with a short and suitable postoperative course.

[Thoracoscopic thymectomy].

BACKGROUND/PURPOSE: The use of videothoracoscopy in thoracic pediatric pathology has been progressively accepted in different diagnostic and therapeutic procedures along last decade. The aim of this work is to analyze our initial experience in thymectomy through this approach. PATIENTS AND METHODS: We have used the thoracoscopic approach in the last two cases of thymus pathology with surgical indication. Case 1: 9 year-old patient recently diagnosed on myasthenia gravis and several hospital admissions because of clinical worsening. Case 2: 9 year-old patient with a 7x8x3.5 cm. cervico-mediastinal tumour. FINAL DIAGNOSIS: Multilocular cystic thymoma. In both cases we used right approach in lateral decubitus, and the harmonic scalpel. RESULTS: Mean operating time was 125 minutes. No procedure-related complications. They were discharged on the 6th and 4th postoperative day. After 6 and 7 month follow-up, no incidences have been found, and case 1 has shown a sympthomatic improvement and a decrease in drug dosage. CONCLUSIONS: Thoracoscopy is a good alternative in thymus approach. Its cosmetic and recovery advantages upon transcervical and transsternal are obvious. Despite our very initial experience, we believe that this approach at least equals classic ones in the ability to resect the whole thymus.

[Transanal endorectal pull-through alone as treatment of Hirschsprung's disease].

UNLABELLED: The aim of this work is to present our experience in the treatment of Hirschsprung's disease (HD) with the technique described by De la Torre. MATERIALS AND METHODS: Seven children diagnosed with recto-sigmoid aganglionism have been treated with this surgical technique, to which a few modifications have been done. RESULTS: There were no intra- nor early postoperative complications. Surgical time ranged 150 to 240 minutes (average 198). All children began oral feedings 2 or 3 days postoperatively (average 2.4). Hospital stay averaged 5.2 days. Follow-up ranges from 6 months to 3 years (average 16 months). Two late complications were seen--one anastomotic stricture and one constipation--and successfully treated as out patients. CONCLUSIONS: The transanal only approach carries a rapid recovery. Family satisfaction is high because of the lack of scars. We believe this is the treatment of choice when confronting rectosigmoid aganglionism.

[Evolution of pre and postoperative renographic parameters in pyeloreteral juntion obstruction syndrome].

With the objective of observing the modifications that the postoperative Diuretic Renography (DR) curve shows and determining how the quantitative parameters of this exploration (Differential Renal Function (DRF), Peak Time (PT), Half Time (HT), descent of maximum activity at 10 min (DMA10)) can be modified, the records of 50 patients affected by unilateral pyeloureteral junction obstruction and without any other associated pathology treated between 1991 and 2001, were revised. The age of the patients was between 1 month and 12 years (average 2 years 7 months). Of the 50 patients, 31 were male and in 28 of the cases were affected on the left side. Patient selection was random. The preoperative evaluation was made using ultrasound (US), intravenous urography (IU), voiding cystourethrography (VCU), and RD. The RD technique and surgical intervention were standardized and the latter were performed by the same surgeon. Postoperative control was made with US and/or IU and RD between 6 and 18 months following surgery, even though total follow up ranged from 6 months to 10 years (average 38.24 months). In all of the cases the follow up US and/or IU results were satisfactory, even though there was residual pyelic ectasia and absence of tension. The morphology of the preoperative curves was mostly obstructive or partially obstructive without lasix response, the curves became normal in 9 cases and partially obstructive with a good response to lasix in 38. The 3 remaining cases that corresponded to the hypofunctional kidney curve did not change. The DRF did not present major variations. The postoperative PT decreased in 62% of the cases. The HT and DMA10 improved in very few cases. In conclusion, it can be said that in spite of a good surgical outcome, the patterns of the postoperative renographic curve often do not completely normalize, major variations in the postoperative DRF are not expected, and with a diminshed postoperative PT a favorable pyeloplasty outcome can be appreciated. HT and DMA10 indicate improvement when they decrease, but do not indicate that the disease has reappeared when they do not change or increase.

[Is laparoscopic surgery the technique of choice in nephrectomy?].

Laparoscopic is performed in adults for the treatment of benign renal diseases. It is widely accepted that laparoscopic surgery has more advantages than open surgery in many procedures such as nephrectomy, but there is no further experience in this technique. In pediatric urology laparoscopy has become an accepted approach for varicocele, non palpable testis, bladder augmentation, adrenalectomy and urinary diversion. We report our experience with 25 laparoscopic nephrectomies in children.

[Predictive value of prenatal MRI in the diagnosis of thoracic congenital malformations].

INTRODUCTION: Magnetic imaging (MI) has an increasing value in the prenatal diagnosis of thoracic malformations. MATERIAL AND METHOUS: We compare in this work the prenatal diagnoses with the prenatal sonographic diagnoses and postnatal imaging, surgical or postmortem findings. RESULTS: Prenatal sonography diagnosed 5 diaphragmatic hernias (CDH) and 3 cystic adenomatoid malformations (CAM). MI confirmed left side CDH in 4 cases, in two of them showing also herniation of the left hepatic lobe and the spleen. In the 5th case, MI suggested diaphragmatic eventration with partial occupation of the right hemithorax by the liver. Two of three CAM appeared to have lung sequestration at MI. At birth, four CDH and one diaphragmatic eventration were confirmed by simple x-ray, and by surgery in all but one, a CDH case who went into ECMO and died without surgery. Pulmonary sequestration was postnatally confirmed by CT scan and arteriography. Treatment was coil embolization of the systemic artery. CAM was confirmed postnatally through plain chest film and CT scan. Surgical resection of the lesion was performed and the pathology exam demonstrated the presumed lesion. CONCLUSIONS: When prenatal sonography suggest a fetal thoracic malformation, MI is the way to accurate diagnosis, follow-up, prognostic evaluation and therapeutic strategy.

[Retroperitoneoscopy: minimally invasive renal surgery].

OBJECTIVE: Retroperitoneal laparoscopy is well known as a surgical technique in adult patients. Its use in pediatric surgery is still-recent but, because of the good results, retroperitoncoscopy indications are getting more acceptance and widening indications. The aim of this work is to analyze our initial experience in retroperitoneal laparoscopy procedures in urological diseases at our centre. PATIENTS AND METHODS: From July 2001 to February 2002 retroperitoneal laparoscopy has been used in 6 patients aged 6 months to 14 years. Surgical indications were: pyelolithotomy (lithiasis non-subsidiary to extracorporeal shock wave lithotripsy (n = 1); nephrectomy ofmulticystic dysplastic kidney (n = 4); and nephrectomy of atrophicpelvic kidney (n = 1). RESULTS: Mean operative time in nephrectomy has been 102 minutes, and 230 minutes in conservative surgery. All 5 patients nephrectomized were discharged 24 hours after operation with no postoperatory incidences. The patient operated on for pyelolithiasis (in which a external drainageand a pyelouretheral stent (pig-tail) was placed) remained one week until he could be discharged without drainage. The pig-tail stent was thrown out spontaneously three weeks later through the urethra. Follow up demonstrated no stenosis in this case and no complications in nephrectomy patients. CONCLUSION: Retroperitoneal laparoscopy is effective and safe in renal surgery and surpasses transperitoneal laparoscopy because its safety in reconstructive surgery avoiding urine leakage risk into the abdomen.

[Mammaplasty in adolescent girls].

The aim of this work is to analyze the experience in our pediatric center on the surgical management of mammary malformation in teenagers. We have reviewed or mammaplasty cases until 1999 (n = 24). We have divided them in two groups: augmentation (A) and reduction (R) mammaplasty. The analyzed parameters were: ethiology, associated pathology, surgical approach, aesthetic results and complications. Group A (n = 14; 17 implants). The surgical indication was moderate-severe mammary hypoplasia with psychological repercussion. Associated pathology: thoracic malformation (n = 13) and psychiatric pathology (n = 2). The surgical approach was submammary in 6 cases, videoassisted transaxillary in 4 and iterative on thoracic scar in 3. All the implants were located at the subglandular space. No major complications were found and the cosmetic results were good, with only one reoperation because of asymmetry. Group R (n = 10). Surgery was indicated because of bilateral puberal mammary hipertrophy in all cases. Associated pathology: obesity (n = 3), psychiatric and behaviour disorders (n = 3), scoliosis (n = 2), and one case of isosexual precocious puberty. In all cases but one the Strömbeck mammaplasty was performed. We used the Lejour technique in this single case. The cosmetic results were good, except for 2 cases of hypertrophic scar. The only complication was a wound infection that healed well.
