Acute scrotal pain in children: results of 543 surgical explorations.

Abstract A total of 543 boys suffering from acute scrotal pain underwent emergency surgery between 1986 and 1996. Of these, 91 had a testicular torsion (TT) (16.8%) and 250 had an appendage torsion (AT) (46%). The cause varied with patient age, with most TTs in newborns and boys of 15 years and most ATs in 10–11-year-olds; 21.5% were operated upon within 6 h of the onset of pain and 69.2% within 24 h. Most stayed in hospital for less than 24 h. Pre-surgical examination identified no criterion for excluding TT. We therefore believe that all children complaining of acute scrotal pain should undergo surgery. As release of an inflamed AT reduces pain, three-fourths of the children benefited directly from surgery.

BACKGROUND This study describes a novel method of intraoperative localization of neuroblastoma with a gamma-detecting probe, to detect in situ tumor binding of radiolabeled 123I- or 125I-metaiodobenzylguanidine (MIBG) and improve the quality of tumor resection. METHODS Fifty-eight children underwent 66 surgical procedures with intraoperative detection of radiolabeled MIBG. All patients with positive MIBG scintiscans at diagnosis were included in the study. A tumor/background ratio exceeding 2:1 at the time of operation was considered positive, indicating a significant uptake of MIBG, compatible with the presence of malignant cells. The surgeons were requested to evaluate the contribution of the method to the surgical procedure. Sensitivity and specificity of the method with either 123I-labeled MIBG or 125I-labeled MIBG, on the basis of correlations between probe findings and pathologic analysis of 288 resected specimens, were determined. RESULTS Intraoperative detection was helpful in 65% of surgical procedures, allowing a better definition of tumor limits and extension to locoregional nodes or detection of small and nonpalpable tumors in sites with difficult surgical access, especially during operation for relapse. The detection was not contributory in 35% of the procedures (well-localized tumors, thoracic neuroblastoma for technical reasons, highly differentiated tumors as ganglioneuroma, and tumors with mainly necrosis or fibrosis). The sensitivity of 123I and 125I was the same (91% and 92%), but the specificity of 125I (85%) was significantly higher than that of 123I (55%) (p < 0.005). CONCLUSIONS First, this study demonstrates the feasibility of intraoperative detection, with radiolabeled MIBG, of neuroblastoma in children. We advocate the use of 125I rather than 123I. Second, the method is useful to improve the quality of macroscopic resection in widespread neuroblastoma with nodal involvement, in sites with difficult access, and in operations for relapse.

Gastrointestinal complications of Schönlein-Henoch purpura are frequent and sometimes severe. However, there seem to be no reports of liver involvement. A child is described in whom Schönlein-Henoch purpura was complicated by bile duct lesions, resulting in biliary cirrhosis and requiring liver transplantation. At surgical removal, the liver had lesions of bile ducts and of adjacent small blood vessels in the hilum, very similar to those complicating hepatic artery thrombosis after liver transplantation. These findings suggest that Schönlein-Henoch purpura can be complicated by vasculitis of the peribiliary vessels resulting in ischemic necrosis of the bile ducts. Schönlein-Henoch purpura can be added to the list of causes of ischemic cholangiopathies.

PURPOSE The effectiveness of laparoscopic diagnosis of contralateral patent processus vaginalis (CPPV) in children with unilateral inguinal hernia was evaluated. METHODS Ninety-three consecutive children under the age of 1 year were operated on for a unilateral inguinal hernia. A contralateral CPPV was diagnosed by laparoscopy via the inguinal hernia sac before ligation. The laparoscopy results of this technique were correlated with those of herniography or inguinal exploration. RESULTS Laparoscopy was performed on 88 patients; sensitivity was 71% and specificity 89%. The only complication arising from the procedure was wound infection in two patients. CONCLUSION This method is a simple, safe, and accurate procedure for selecting children for contralateral surgical exploration.

Abstract A lipoma of the preputium clitoridis was found in a newborn girl. Ambiguous genitalia was first suspected. Surgery was successfully performed at 5 months.

Pleuroperitoneal shunt in the management of chylothorax caused by thoracic lymphatic dysplasia

Guillaume Podevin; Guillaume Levard; Michèle Larroquet; M. Gruner

Three cases of intractable chylothorax secondary to thoracic lymphatic dysplasia were treated by pleuroperitoneal shunt insertion. These cases included one with Gorhams syndrome, and one case with a bilateral chylothorax and chylous ascites. Pleuroperitoneal shunts allowed an adequate internal drainage in all cases, alleviating protein and lymphocyte losses caused by recurrent pleural taps. In the third case with chylous ascites, valved shunts were used to avoid reflux between the peritoneal cavity and the pleural space. Such palliative therapy did not change the bad prognosis of these patients with lymphatic disorders but improved the childrens quality of life.
