[Total mobilization of the urogenital sinus in the treatment of cloaca].

Persistent cloaca is one of the most complex forms of anorectal malformation in girls. Surgical treatment is complicated and laborious especially when the common channel is long. The aim of this report was to emphasize the importance of the joint mobilization of the urogenital sinus after separation from the rectum. This maneuver avoids separation of the urinary tract from the genital tract and reduces operating time by more than 60 %. This is only possible when the common channel of the cloaca is less than 3 cm. We present the cases of two girls treated in the last 2 years with this technique. Operating time was significantly shortened to approximately 4 hours and the procedure was considerably simplified. The functional and cosmetic results were excellent. To obtain good results in the treatment of cloaca, a precise clinical and radiologist diagnosis must be made, surgical needs should be prioritized and the appropriate technique chosen. The best procedure for patients whose common channel is less than 3 cm is total mobilization of the urogenital sinus, subsequently sutured to the perineum, and placement the rectum within the anorectal sphincter complex.

[CO(2) laser treatment of sialolithiasis].

Sialolithiasis of the submaxillary gland is rare in the pediatric population. We report the case of a 13-year-old boy who presented submandibular tumefaction of 7 months evolution, which increased after meals. Localized lithiasis in Wharton s duct was observed in submaxillary sialolithiasis. Treatment was intraoral extraction with CO(2) laser and after recovering from the anesthetic, the patient was discharged.This technique shortens surgical time, facilitates hemostasia and reduces edema and postoperative pain. The procedure is suitable for ambulatory surgery.

[Neuroblastoma with bone marrow invasion. A multicenter study. Work Group of the Spanish Society of Pediatric Surgery].

By means of a retrospective study made of multiple centres, it was aimed to determine which variables could be influential at the moment of diagnosis in the prognostic of patients suffering neuroblastoma and medullary bone affection. Fifty four cases of patients belonging to a total of ten hospital centers have been revised in a period of five years. The ages under study spanned from three months to eight years of age (mean = 2.83 years). For the analysis of the patients, they were divided into two groups: one being composed of the deceased patients and the other of the surviving. The deceased patients were of a more advanced age, the delay in the diagnosis was greater, the primitive tumor was found to be more frequently located in the adrenal glands, the metastasis appeared more readily in multiples, and the effectiveness of the treatment was less, resulting in lower cases of remission and a less radical surgery. The only difference with respect to other publications is that in the case of surviving patients, the number of cases of enolase and ferritin is more frequently pathological.

[Simultaneous bilateral Wilms tumor].

Bilaterality is uncommon in Wilms' tumor, being present in 4% to 8% of the cases. Definite progress has been made in the treatment with marked improvement in prognosis. The recent trend toward more conservative sugery, preoperative chemotherapy an avoidance of high-dose radiation therapy has yielded good results. This is confirmed in our two cases with synchronous tumors.
