Operative findings in antenatal abdominal masses of unknown etiology in females.
ABSTRACT Perinatal findings of abdominal masses pose a diagnostic challenge to clinicians. This study presents the operative findings of patients who underwent exploration for perinatally identified abdominal masses of unknown etiology.
Retrospective review of all patients with abdominal masses of unknown etiology identified in the antenatal period was conducted from January 1, 2000 to July 1, 2010. Patient demographics were collected. Preoperative radiographic studies, operative findings, and pathologic evaluation were reviewed.
There were 17 patients identified within the study period. The median age was 30 d at the time of operation (range 0-287 d). The median height was 51 cm (range 45-77 cm), and the median weight was 4.0 kg (range 2.6-10.4 kg). All patients were asymptomatic. After birth, ultrasound identified abdominal masses in 14 patients, and computed tomography scan was used in four patients where one patient had both an ultrasound and a computed tomography scan. Mass resection was performed using laparoscopy in 15 patients, whereas two patients underwent open resection. At the time of surgery, 11 patients were diagnosed with ovarian cysts, four patients with ovarian torsion with an associated cyst, and two patients with an enteric duplication cyst. On final pathology, eight patients had benign ovarian cysts, seven patients had hemorrhagic ovarian necrosis, and two patients had duplication cysts.
Females with antenatally identified abdominal masses of unknown etiology appear to be benign in nature. In this series, a benign ovarian cyst is the most common diagnosis, and these lesions can be approached laparoscopically.

ABSTRACT: We report five infants in whom antenatal diagnosis of choledochal cyst was established by ultrasonography, and we review the seven previously reported cases. All but one infant had cystic dilatation of the common bile duct (type 1 cysts), and all infants were diagnosed during the second or third trimester. Eight of 12 infants (67%) developed jaundice in the first few days of life, but only 25% had a palpable abdominal mass. Seven of nine infants (78%) demonstrated complete obstruction of the distal common bile duct on intraoperative cholangiography. Liver histology was available for six patients. Five of six had cirrhosis or fibrosis with bile duct proliferation. All of the infants with fibrosis or cirrhosis had distal common bile duct obstruction. Despite liver biopsy findings of extensive fibrosis plus ascites with failure to thrive in one of our patients, all five patients demonstrated clinical and biochemical improvement following surgical excision and porto- or choledochoenterostomy. All were free of symptoms by 6 months of age. Congenital choledochal cyst should be considered in the differential diagnosis of any sonolucent abdominal mass of the fetus. Neonates with distal common bile duct obstruction and fibrosis in association with presumed choledochal cyst should have prompt surgical exploration, intraoperative cholangiography, and close postoperative follow-up. The long-term outcome with prompt surgical correction is excellent.Journal of Pediatric Gastroenterology and Nutrition 03/1994; 18(2):142-5. · 2.87 Impact Factor

ABSTRACT: Fetal ovarian cysts are frequently complicated by intracystic hemorrhage without associated clinical signs, which is often secondary to ovarian torsion leading to loss of the ovary. The aim of this study was to evaluate ovarian outcome and the place of prenatal management and surgery in the first few days of life in order to save the ovary. Between January 1987 and June 2006, 82 fetal ovarian cysts in 79 patients were managed and clinically and ultrasonographically followed up for several months (median, 11 months; range, 6 months to 10 years) in all of the cases where the ovary was not removed. The ultrasonographic results regarding the ovarian parenchyma were broken down into 3 categories: follicular ovary, homogeneous ovary, and undetected ovary. Twenty-seven cysts remained simple throughout their evolution, and 55 were complicated by intracystic hemorrhage usually several weeks before birth. Overall, after disappearance of the cyst, a follicular ovary was detected in only 39% of the cases (32/82) and more often when the cyst was simple than when it presented an intracystic hemorrhage (85% vs 16.4%, chi(2), P < .0001). A review of our series confirms the poor ovarian outcome linked to ultrasonographic signs of intracystic hemorrhage. Preventive action by puncture of "simple" cysts is still being studied. The presence of a bilateral cyst can, if pulmonary maturity has been reached, be an argument for inducement of premature birth with a view to performing conservative surgery. After birth, surgery in the first few days of life is only justified if the signs of intracystic hemorrhage appeared in the period very close to birth.Journal of Pediatric Surgery 12/2008; 43(11):2004-9. · 1.31 Impact Factor

ABSTRACT: Alimentary tract duplications are rare congenital malformations that occur most commonly in the jejunoileal part of the gastrointestinal tract. Management of this pathologic condition is usually drawn up. We report a case of descending colonic communicating duplication in which clinical presentation and anatomopathologic results were unexpected. A slightly echogenic abdominal mass reaching 72 x 36 mm in the left flank was diagnosed in a female fetus during the third trimester ultrasound examination. At birth, volume of the mass rapidly evolved, and despite no intestinal obstruction was observed by compression of the adjacent gastrointestinal tract, abdomen was distended. Abdominal plain film showed a large air collection, and the barium enema demonstrated a slight leak of contrast in the aerated mass, suggesting a communication with the sigmoid colon. No other abnormalities were seen. The patient underwent surgery in emergency. The mass was then totally excised through an antimesenteric resection of the tubular tract joining cystic mass and sigmoid colon. A lateral suture of the colon was subsequently performed. The wall of the duplication is usually composed of a smooth muscle layer covered by an epithelium, mostly of intestinal type. Herein, we describe a descending colonic duplication completely lined with nonkeratinizing squamous epithelium. Therefore, the association of a colonic mucosa (of endodermic origin) and a squamous epithelium (derived from the ectoderm) in our case is an interesting finding and is not explained by the various theories. Furthermore, the clinical characteristics, diagnosis, and treatment of intestinal duplications are discussed with regard to literature.Journal of Pediatric Surgery 10/2009; 44(9):1831-4. · 1.31 Impact Factor
