Primary repair is preferred in the neonatal period with a very nice fistula; older patients may require colostomy
Clinical
Primary repair can be performed up to 3-4 months of age if surgeon is confident; otherwise two-operation approach is used
Clinical
Teenagers repaired with classical three-operation approach have beautiful perineum and perfect function
Clinical
Patients repaired primarily 7-8 years ago have more stenosis and adhesions because feces pass through during healing even with fasting
Clinical
Vestibular fistula patients with normal sacrum and no cord have excellent prognosis with good operation
Clinical
For babies born in hospital, operate within first 72 hours before colonization occurs
Clinical
For 6-month-old baby with megacolon, clean colon with GoLYTELY completely, then central line with 7-10 days NPO on parenteral nutrition before repair
Clinical
Oval-shaped anus with no radiating streaks is very specific for Currarino syndrome
ClinicalSabine
Presacral mass corresponds to either anorectal stenosis (mass just in front of stenosis) or Currarino syndrome
ClinicalSabine
Opening colostomy in fixed portion of colon (end of descending colon) prevents prolapse
Clinical
Opening colostomy in mobile portion of colon will cause severe prolapse
Clinical
Mucous fistula should be reduced in size and made tiny, only necessary for irrigation and diagnostic tests
Clinical
Transverse colostomy dysfunctionalizes a very long piece of colon
Clinical
It is extremely difficult to do a good distal colostogram through transverse colostomy because of difficulty applying enough hydrostatic pressure
Clinical
Colon perforation with distal colostogram occurred mainly through transverse colostomy
Clinical
Cleaning colon distal to transverse colostomy is almost impossible, leaving pool of meconium that colonizes
Clinical
With transverse colostomy and rectourinary fistula, urine gets trapped in colon, is absorbed, and can cause hyperchloremic acidosis
Clinical
Long-term transverse colostomy causes distal colon to become extremely dilated and full of meconium
Clinical
There is a direct relationship between degree of megacolon and degree of constipation the patient will have
Clinical
Loop colostomies have more prolapse than separated colostomies
Clinical
For laparoscopic repair, distal colostomy can act as traction to help dissect fistula, then take down and open new one simultaneously
Clinical
Cloaca is rarely diagnosed prenatally in second trimester; third trimester ultrasound more common
Clinical
Midline abdominal mass in cloaca patient is always hydrocolpos; never seen a cloaca with that mass that was not hydrocolpos
Clinical
Hydrocolpos compresses bladder trigone and produces acquired ureterovesical obstruction with megaureters and hydronephrosis
Clinical
Draining hydrocolpos makes hydronephrosis disappear
Clinical
Unnecessary nephrostomy, ureterostomy, or vesicostomy may be performed if urologist does not recognize that hydrocolpos drainage is the key
Clinical
Consequences of not draining hydrocolpos are urosepsis and infected hydrocolpos (pyocolpos) that permanently damages vagina
Clinical
Transperineal catheter drainage of hydrocolpos will come out in two days and hydrocolpos will reform
Clinical
Drain hydrocolpos with permanent catheter through abdomen, not by dilating common channel
Clinical
Interventional radiology can drain hydrocolpos under ultrasound guidance if it is large enough and close to abdominal wall
Clinical
Vesicostomy is indicated when common channel is almost atretic and baby has difficulty emptying bladder after hydrocolpos drainage
Clinical
For vestibular fistula, Professor Liam prefers primary repair around day 5-7 of life
Host summaryEm Gootee summarizing the discussion · not cited in answers
About 30-40% of anorectal stenosis or rectal atresia cases will have a presacral mass
Host summaryEm Gootee summarizing the discussion · not cited in answers
MRI is the best way to show a presacral mass

For anorectal stenosis repair, open posteriorly only to preserve anterior dentate line and avoid anterior rectal dissection

Loop colostomy is never completely diverting no matter how much surgeons believe it is

Spillage across loop colostomy causes urinary tract infections in patients with fistulas

Cleaning out distal colon at colostomy creation takes about 20-30 minutes and is very important
Host summaryEm Gootee summarizing the discussion · not cited in answers
Distal sigmoid colostomy makes laparoscopic operation more difficult and may require opening to take down mucous fistula
Host summaryEm Gootee summarizing the discussion · not cited in answers
Best tube for hydrocolpos drainage is curled pigtail tube because hydrocolpos recedes into pelvis over months; straight tube will fall out
