Evaluation is in the form of a dye disappearance test followed by irrigation test. By using this sequence (with modifications) as a guide, the physician can frequently streamline diagnostic testing.
The dye disappearance test (DDT) is useful for assessing the presence or absence of adequate lacrimal outflow, especially in unilateral cases. It is more heavily relied upon in children, in whom lacrimal irrigation is impossible without deep sedation. Using a drop of sterile 2% fluorescein solution or a moistened fluorescein strip, the examiner instills fluorescein into the conjunctival fornices of each eye and then observes the tear film, preferably with the cobalt blue filter of the slit lamp. Persistence of significant dye and, particularly asymmetric clearance of the dye from the tear meniscus over a 5-minute period indicate an obstruction. If the DDT result is normal, severe lacrimal drainage dysfunction is highly unlikely. Variations of the DDT are the Jones tests.
Diagnosis of epiphora is clinical by history presentation and observation of the lids. Fluorescein dye can be used to examine for punctal reflux by pressing on the canaliculi in which the clinician should note resistance of reflux as it irrigates through the punctum into the nose.
An imperforate lacrimal punctum is a congenital disorder of dogs involving the lack of an opening to the nasolacrimal duct (tear duct) in the conjunctiva. Dogs normally have two lacrimal puncta, the superior and inferior. This condition can affect either or both. Symptoms include excessive tearing and tear staining of the hair around the eye. Affected breeds include the American Cocker Spaniel, Bedlington Terrier, Golden Retriever, Poodle, and Samoyed. Imperforate lacrimal puncta can be corrected by surgical opening of the punctum.
If epiphora is caused by ectropion or entropion, lid repair is indicated. Punctal irrigation is also required. In infants with nasolacrimal defects, a nasolacrimal duct probe is used and a tube replacement, either temporary (Crawford) or permanent (Jones), is carried out. A surgical procedure called a dacryocystorhinostomy is done to join the lacrimal sac to the nasal mucosa in order to restore lacrimal drainage.
An imperforate hymen is most often diagnosed in adolescent girls after the age of menarche with otherwise normal development. In adolescent girls of menarcheal age, the typical presentation of the condition is amennorhea and cyclic pelvic pain, indicative of hematocolpos secondary to vaginal obstruction. An imperforate hymen is usually visible on vaginal inspection as a bulging blue membrane. If hematocolpos is present, a mass is often palpable on abdominal or rectal examination. The diagnosis of an imperforate hymen is usually made based purely on the physical exam, although if necessary the diagnosis can be confirmed by transabdominal, transperineal or transrectal ultrasound.
An imperforate hymen can also be diagnosed in newborn babies and it is occasionally detected on ultrasound scans of the foetus during pregnancy. In newborns the diagnosis is based on the findings of an abdominal or pelvic mass or a bulging hymen. Examination of the normal neonatal vagina usually reveals a track of mucus at the posterior commissure of the labia majora; an absence of mucus may indicate an imperforate hymen or another vaginal obstruction.
A similar condition, cribriform hymen, is diagnosed when the hymen contains many minute openings.
Ultrasounds can be used to diagnose anophthalmia during gestation. Due to the resolution of the ultrasound, however, it is hard to diagnose it until the second trimester. The earliest to detect anophthalmia this way is approximately 20 weeks. 3D and 4D ultrasounds have proven to be more accurate at viewing the fetus's eyes during pregnancy and are another alternative to the standard ultrasound.
Physicians, specifically ophthalmologists, can examine the child and give a correct diagnosis. Some will do molecular genetics tests to see if the cause is linked with gene mutations.
An omphalocele is often detected through AFP screening or a detailed fetal ultrasound. Genetic counseling and genetic testing such as amniocentesis are usually offered during the pregnancy.
The prognosis for vaginal atresia is one that is complicated. There are variations in patients' anatomic findings as well as an absence in consistent surgical techniques which makes it difficult to give a prognosis for this condition. Along with other conditions that give rise to an abnormal perineum (i.e. ambiguous genitalia and other various abnormalities that range from cloaca to urogenital sinus), individuals with vaginal atresia often report reconstruction as an outcome of treatment. Due to this, it is difficult to compare outcomes between individuals with vaginal atresia.
Before surgical intervention in adolescents, symptoms can be relieved by the combined oral contraceptive pill taken continuously to suppress the menstrual cycle or NSAIDs to relieve pain. Surgical treatment of the imperforate hymen by hymenotomy typically involves making cruciate incisions in the hymen, excising segments of hymen from their bases, and draining the vaginal canal and uterus. For affected girls who wish (or whose parents wish) to have their hymens preserved, surgical techniques to excise of a central flange of the hymen can be used. The timing of surgical hymen repair is controversial: some doctors believe it is best to intervene immediately after the neonatal period, while others believe that surgical repair should be delayed until puberty, when estrogenization is complete.
Fertility options for girls and women with Rokitansky-Mayer-Küster-Hauser syndrome has a bit more information. Girls and women who are born without a complete vagina, but still have a regular sized uterus more than likely will be able to become pregnant and have a baby. However, if the female is born with a tiny uterus, or without a uterus, they will not be able to have a baby. As the ovaries may be normal in this case, the egg may be fertilized with a donor's or partner's sperm. In this case, surrogacy, would be an option where there will be a gestational carrier to carry the pregnancy for the couple. Adoption may also be an option for females with Rokitansky-Mayer-Küster-Hauser syndrome. Another possibility could be uterine transplants, however this a new and developing form of treatment. Fertility options are being researched daily, so there can always be a new method available.
Any pain associated with Rokitansky-Mayer-Küster-Hauser syndrome comes from menstruation related cramping and can be treated with several ways. Individuals with this syndrome may be born with a uterine remnant (tiny uterus), which can fill with become filled with blood in the pelvic cavity causing pain. A medical professional can assess the severity of having a uterine remnant within each patient to determine if removal of the uterus is necessary.
When an infant is born with an anorectal malformation, it is usually detected quickly as it is a very obvious defect. Doctors will then determine the type of birth defect the child was born with and whether or not there are any associated malformations. It is important to determine the presence of any associated defects during the newborn period in order to treat them early and avoid further sequelae. There are two main categories of anorectal malformations: those that require a protective colostomy and those that do not. The decision to open a colostomy is usually taken within the first 24 hours of birth.
Sonography can be used to determine the type of imperforate anus.
With a high lesion, many children have problems controlling bowel function and most also become constipated. With a low lesion, children generally have good bowel control, but they may still become constipated.
For children who have a poor outcome for continence and constipation from the initial surgery, further surgery to better establish the angle between the anus and the rectum may improve continence and, for those with a large rectum, surgery to remove that dilated segment may significantly improve the bowel control for the patient. An antegrade enema mechanism can be established by joining the appendix to the skin (Malone stoma); however, establishing more normal anatomy is the priority.
The prognostic outcomes for this type of cloaca are good for bowel control and urinary function. The surgical repair for this type of cloaca can usually be done by performing posterior sagittal approach without opening of the abdomen. A common channel longer than 3 cm in length usually has poor sphincter muscles and a poor sacrum, suggesting a prognostic outcome for bowel control and urinary function to be less likely. Common channels longer than 3 cm are generally considered more complex and more technically challenging in surgical repair.
The main causes are Müllerian agenesis and complete androgen insensitivity syndrome.
The most extensive epidemiological survey on this congenital malformation has been carried out by Dharmasena et al and using English National Hospital Episode Statistics, they calculated the annual incidence of anophthalmia, microphthalmia and congenital malformations of orbit/lacrimal apparatus from 1999 to 2011. According to this study the annual incidence of congenital microphthalmia in the United Kingdom was 10.8 (8.2 to 13.5) in 1999 and 10.0 (7.6 to 12.4) in 2011.
This condition takes several different forms, often involving one or more fistulas connecting the trachea to the esophagus (tracheoesophageal fistula).
This condition may be visible, after about 26 weeks, on an ultrasound. On antenatal USG, the finding of an absent or small stomach in the setting of polyhydramnios was considered a potential symptom of esophageal atresia. However, these findings have a low positive predictive value. The upper neck pouch sign is another sign that helps in the antenatal diagnosis of esophageal atresia and it may be detected soon after birth as the affected infant will be unable to swallow its own saliva. Also, the newborn can present with gastric distention, cough, apnea, tachypnea, and cyanosis. In many types of esophageal atresia, a feeding tube will not pass through the esophagus.
After diagnosing rectovaginal fistula, it is best to wait for around 3 months to allow the inflammation to subside. For low fistulae, a vaginal approach is best, while an abdominal repair would be necessary for a high fistula at the posterior fornix.
A circular incision is made around the fistula and vagina is separated from the underlying rectum with a sharp circumferential dissection. The entire fistulous tract, along with a small rim of rectal mucosa is incised. The rectal wall is then closed extramucosally.
Most rectovaginal fistuals will need surgery to fix. Medications such as antibiotics and Infliximab might be prescribed to help close the rectovaginal fistula or prepare for surgery.
Tight hymenal ring is a disorder of the hymen, characterized by a rigid hymen and tight introitus, whether acquired or congenital. It excludes an imperforate hymen.
The condition can be relieved by outpatient surgery or manual dilation.
In order to facilitate sexual intercourse, the main treatments are self-dilation methods (using intra-vaginal cylinders of increasing size) and surgical vaginoplasty to lengthen the vagina.
Self-dilation has a high success rate, estimated at 75%, and is usually the first-line treatment due to low surgical invasiveness. Overall, the complication rates are significantly lower with dilation than with vaginoplasty.
Surgery is indicated when there is inability or reluctance to perform self-dilation, or where it is performed but with failed result. One appropriate surgical variant is the "Vecchietti technique". In this procedure, an olive-shaped pressure device is pressed towards the potential vaginal space by a thread that goes through the skin, behind the urinary bladder and pubic bone and exits the skin in the hypogastrium, where it is attached to a plate that provides counter-traction. Vaginoplasty can also be performed using a skin graft or an intestinal graft. Traction vaginoplasty such as the "Vecchietti technique" seems to have the highest success rates both anatomically (99%) and functionally (96%), whereas skin graft procedures and intestinal procedures have the lowest successful outcomes (83–95%).
After vaginoplasty, available evidence suggests that continued self-dilation is needed to maintain patency in periods of coital inactivity.
Management of most fetal SCTs involves watchful waiting prior to any treatment. An often used decision tree is as follows:
- Perform detailed ultrasound exam including fetal echocardiogram and Doppler flow analysis
- If fetal high output failure, placentomegaly, or hydrops
- If fetus not mature, perform pregnancy termination or fetal intervention
- Else fetus mature, perform emergency Cesarean section
- Else no emergent problems, perform serial non-stress tests and ultrasound biophysical profiles and plan delivery, as follows
- If emergent problems develop, return to top of decision tree
- Else if SCT over 5–10 cm or polyhydramnios, perform early (37 weeks gestation) elective Cesarean section
- Else SCT small and no complications, permit term spontaneous vaginal delivery
Emergent problems include maternal mirror syndrome, polyhydramnios, and preterm labor. Poor management decisions, including interventions that are either premature or delayed, can have dire consequences. A very small retrospective study of 9 babies with SCTs greater than 10 cm diameter reported slightly higher survivorship in babies remaining in utero slightly longer.
In many cases, a fetus with a small SCT (under 5 or 10 cm) may be delivered vaginally. Prior to the advent of prenatal detection and hence scheduled C-section, 90% of babies diagnosed with SCT were born full term.
SCTs are very rare in adults, and as a rule these tumors are benign and have extremely low potential for malignancy. This estimation of potential is based on the idea that because the tumor existed for decades prior to diagnosis, without becoming malignant, it has little or no potential to ever become malignant. For this reason, and because coccygectomy in adults has greater risks than in babies, some surgeons prefer not to remove the coccyx of adult survivors of SCT. There are case reports of good outcomes.
PELVIS syndrome is a congenital condition characterized by perineal hemangioma, external genitalia malformations, lipomyelomeningocele, vesicorenal abnormalities, imperforate anus, and skin tag.
