[Gastric volvulus in childhood].

Gastric volvulus in children might be observed both as an acute form, characterized by gastric necrosis with sudden perforation and patient's death and as an idiopathic or chronic form with a less severe insurgence that causes epigastric pain, vomit and gastric distension. The latter could resolve spontaneously but recurs frequently. The acute form rises in newborns and toddlers and is often associated with a diaphragmatic defect; the idiopathic forms are correlated on the opposite to a fixation deficit of the stomach which is held in place by the gastro-colic, gastro-hepatic, gastro phrenic and gastro-splenic ligaments. Since a diagnostic mistake could cause the patient's death gastric volvulus must be carefully considered as a possible cause of acute epigastric pain with vomit. In the two forms surgical therapy is mandatory for the simultaneous correction of both the anatomical defects of gastric fixation and malposition and the diaphragmatic ones. The case presented is an example of an acute gastric volvulus in a 2-year-old male child affected by a diaphragmatic defect The peculiar aspect of this case consists in the age of arousal being more usual in an earlier age An appropriate surgical treatment has permitted the patient's recovery.

Indications for bladder augmentation in the exstrophy-epispadias complex.

OBJECTIVE: To determine whether bladder augmentation has a role in avoiding urinary diversion in patients with exstrophy-epispadias complex (EEC), whether it can improve the lifestyle in patients who have previously undergone diversion or improve the result of any single surgical step in the staged functional reconstruction of the bladder in these patients. PATIENTS AND METHODS: From 1970 to 1991, 85 patients were treated for EEC. Between 1981 and 1991, 12 bladder augmentations were performed in 11 patients (seven girls and four boys) with bladder exstrophy, male epispadias (one case) and cloacal exstrophy (one case). RESULTS: No significant early surgical complications were reported. Follow-up ranged from 18 months to 11 years. Late complications included bowel obstruction in one patient, a partial left ureteric stenosis at the level of the anastomosis with the gastric patch wall in one patient and bladder lithiasis in five patients (sigmoidocystoplasty in one and ileocystoplasties in four). No metabolic problems, no bladder perforations or malignancies were observed. The results on continence were good and, with the one exception reported, the condition of the upper urinary tract following surgery was satisfactory in all patients. CONCLUSION: Augmentation cystoplasty is of use in the treatment of patients with bladder exstrophy when staged functional reconstruction is unsuccessful. This technique greatly reduces the indications for urinary diversion and can be used in the surgical treatment of EEC. The only disadvantage is that clean intermittent catheterization must be performed, sometimes only temporarily, but patient acceptance is usually high.

Solitary polyp of posterior urethra in children: report on seventeen cases.

Seventeen cases of a solitary polyp of posterior urethra in children (ages ranged between 4 months and 12 years) are presented. All patients were treated endoscopically using a 10 Fr. pediatric cystoscope, equipped with a straight ahead lens, and a Bugbee 3 Fr. electrode to fulgurate the stalk of the polyp through the urethra, without meatotomy. No complications or relapses are recorded, which proves the safety and the efficiency of the transurethral endoscopic resection in all pediatric ages. With the exception of one case, the smallest polyp of the series, lost because entirely burnt during the electrocution, all polyps were recuperated and examined histologically. The dimensions of the polyps ranged from 4 mm to 27 mm length. Their shape varied from a long "cordon-like" peduncle to a short stalk, "balloon-like" appendix. The histologic features were similar, the main component was an axis of connective tissue and vessels, surrounded by transitional epithelium, usually described as a fibroepithelial polyp.

Cosmetic reconstruction of the mons veneris and lower abdominal wall by skin expansion as the last stage of the surgical treatment of bladder exstrophy: a report of three cases.

The results of the correction of the medial scar depression and diastasis of the pubic hair of the mons veneris in three postpuberal female patients operated on for bladder exstrophy are reported. The reconstructive surgery is carried out using skin expanders. The expanded skin is utilized to create two dermoadipose flaps to fill the medial depression, to outline again the public hair areas, and to allow sutures without tension.

[Ureteral ectopy. The residual stump syndrome].

Anatomy and symptoms of ureteral ectopy in childhood can greatly vary. In most cases the site of ectopies in the urethral tract, so that a complete excision of the distal ureter is difficult and may cause damage to the sphincteric structures. When lower ureterectomy is performed below iliac vessels, symptoms secondary to residual ectopic ureter are rare. In our experience, residual ureteral stumps were symptomatic in two cases, with continence and micturation disturbances, which were codified as "residual ureteral stump syndrome". Clinical features and treatment are herein reported.

[Valves of the anterior urethra without diverticulum. Description of 3 cases].

Anterior urethral valves are rare entities, especially in case they are not associated to urethral diverticulum. Because of their obstructive effects on the urinary tract, they must be searched in case of clinical evidence of lower obstructive uropathy. Three cases of anterior urethral valves without urethral diverticulum are herein reported. Differential diagnosis with urethral diverticula, endoscopic features and treatment are discussed and emphasized.

[Further experience with the use of gastrointestinal segments in bladder reconstruction in the complex of exstrophy-epispadias].

It is a matter of discussion if bladder augmentation should or should not utilize in the treatment of exstrophy-epispadias complex. When staged functional bladder reconstruction is adopted in the most difficult cases, or when one desires to avoid early and/or subsequent urinary diversions, sometimes a bladder enhancement could be necessary. The indications should be: a progressive damage to the upper urinary tract, after bladder closure at birth, due to a very small, no compliant detrusor plate (this is a rare condition: only one case in our series); a bladder capacity < or = 80 mls at the time of bladder neck reconstruction (this is a frequent but questionable condition: three cases in our series); a progressive damage of the upper urinary tract after bladder neck reconstruction (this is an unexpected, but not rare condition: 3 cases in our series); during every undiversion procedure (bladder augmentation is nearly mandatory during undiversion in cloacal or bladder exstrophies previously diverted: 4 cases in our series). In our experience, 12 bladder augmentations (in 11 patients, over 85 cases we observed) were done at median age of 8 years and 5 months. Different intestinal segments have been used: the sigmoid colon, the ileo-cecal portion, an ileal tract and the stomach. Follow-up ranges from 11 years to 12 months; until now, we observed few surgical complications: a bowel obstruction in one patient, a left ureteral partial stenosis at level of the anastomosis with the gastric patch wall in another patient and bladder lithiasis in 5 patients.(ABSTRACT TRUNCATED AT 250 WORDS)
