Diagnostic and therapeutic laparoscopy for nonpalpable testis.

BACKGROUND: We evaluated the use of laparoscopy in the management of impalpable testis to determine what advantages it might offer over the open approach. METHODS: Over a 5.5-year period, a total of 46 patients with 53 nonpalpable testes underwent a laparoscopic procedure at our hospital. There were 28 cases of intraabdominal testis (52.83%), 18 cases of the vas and vessels entering the internal ring (33.96%), and seven cases of intraabdominally absent testis (13.20%). We performed a laparoscopic orchiopexy for 24 testes (scrotal in 21 cases and partial to the inguinal canal in three cases) and an orchiectomy for three testes. We encountered inguinal hernia in 14 cases (26.41%). RESULTS: At follow-up, all testes were the same size as at the time of operation and were well positioned in the scrotum, except for four testes that required reoperation due to partial migration at the superficial inguinal ring. The operating time was <1 h in unilateral cases and <2 h for the bilateral cases. All procedures were completed successfully without conversion or complications. CONCLUSIONS: Laparoscopy is the only exploratory procedure that is accurate enough to enable the diagnosis of nonpalpable testis and also allow the surgical treatment to be done in the same setting.

[Indications of transduodenal papillotomy for choledochal cyst].

UNLABELLED: The Choledochal Cyst is a dilatation of the biliary tract whose etiology is still under debate. OBJECTIVE: This paper analyzes the cases of our group an contributes on the indications of transduodenal papilotomy in the surgical treatment of this process. MATERIAL AND METHODS: Seven cases diagnosed as choledochal cysts are presented with mean age between 3 and 10 years (5 females and 2 males). Six cases were presented with abdominal pain, four with jaundice, three presented with biliary stones and one cases was a casual discovery during an US examination. In all cases US and magnetic resonance cholangiopancreatography (MRCP) were performed as preoperative work-up. In one case an endoscopic retrograde cholangiopancreatography (ERCP) was made. In all cases intraoperative cholangiography was carried out. The surgical treatment was quistectomy and hepatico yeyunostomy Roux-Y in four cases; in one of them a transduodenal papilotomy was added. Cholecystectomy and transduodenal papilotomy was made in three cases, two of them presented choledocholithiasys. RESULTS: All patients are symptoms free after a mean follow up period of 2 years and 3 months (range: 1 year and 6 months to 4 years and 10 months). In one case persists dilated choledochal distal stump on MRCP.

[Laparoscopy in the non-palpable testicles. Is it always necessary?].

In order to know the role of diagnostic laparoscopy with non palpable testicles (NPT), 15 children with 16 NPT were studied. Middle age was 7 years (R: 2-12). The surgical procedure was: laparoscopy initially and open inguinal surgery (OIS) after that. Six NPT were discovered with laparoscopy (37.5%). With OIS inguinal hernia was present in 4 cases, with testicle into the inguinal sac in 3 cases; 12 cases had not inguinal hernia, and 6 of them showed spermatic vessel and vas deferent without testicle. Orquidopexy of the 6 located testicles and testicular prothesis implantation in the other 10 cases, were performed. Finding of laparoscopy and OIS were perfectly correlated. Laparoscopy made the diagnosis in 7 cases, which the OIS would have been unable to do it (43.7%). In the other 9 cases, the OIS would have been diagnostic enough (56.2%) without laparoscopy. For those results, the authors prefer to begin the surgical procedure with OIS and if the spermatic vessels are no located, then the laparoscopy is done under the same anesthesia.

[Clinical aspects of infantile megaureter].

84 patients with 126 megaureteres, are studied. There are some clinical differences depending on the type of megaureter and the patient's age. The number of asymptomatic cases is increasing due to ultrasonography during fetal and neonatal period. The younger the patient the more unspecific the symptomatology. Fever, anorexia, failure to gain weight and vomits are the most frequent symptoms in babies. In patients over 6 years of age a more specific symptomatology is present, such as dysuria and lumbar pain. Failure to gain weight is more frequent in cases of refluxing megaureter, especially when they are caused by obstructive uropathy, and when they are bilateral. A urological check up is recommended during fetal ultrasonography: in babies with failure to thrive; in all cases of urinary tract infection; and in micturition disorders.

[Venous aneurysms of the neck in childhood (author's transl)].

Three children with four fusiform venous aneurysms in the neck are described. A correct referral clinical diagnosis had not been established in any of these children. The diagnosis should be made generally on the basis of the physical examination, including the test of the "digital pressure", which is particularly useful to rule out a laringocele. Three of the aneurysms have been treated by surgical removal. Histological examination showed microscopic changes which were related to the time elapsed since the mass was first noticed. Areas of thinning out and sclerosis of the venous wall were evident in one case. The patient with the remaining aneurysm is being followed closely.
