Colorectal Quiz: Episode 42 - HD Constipation
Approximately one-third of Hirschsprung patients are constipated post-operatively and need proactive, aggressive management to avoid trouble
epidemiologicalMarc Levitt1:47 ↗
Hirschsprung disease is a very anatomically fixable problem and with a good operation you should get a good result
clinicalMarc Levitt1:38 ↗
Surgeons might leave behind the dilated segment right above the aganglionic segment as an anatomic reason for decompensation
clinicalMarc Levitt2:11 ↗
The most relevant reason for decompensation is that the patient never figured out how to successfully empty their sphincters and the pull-through decompensates
clinicalMarc Levitt2:22 ↗
Calretinin hangs out with ganglion cells, so normal calretinin staining provides double evidence of good ganglion cells
clinicalMarc Levitt3:14 ↗
In younger children age less than 3 or so, hypertrophic nerves are defined as greater than 40 microns in diameter
clinicalJason Frischer3:47 ↗
The definition of hypertrophic nerve is more gray in older patients and in patients who have chronic constipation issues
clinicalJason Frischer4:01 ↗
If there are no ganglion cells and no calretinin staining, that is a retained Hirschsprung and the patient needs a redo to a higher level
clinicalMarc Levitt4:27 ↗
Nerve hypertrophy with good ganglion cells could represent transition zone or could represent that the bowel has decompensated over time because it hasn't emptied and gotten dilated
clinicalMarc Levitt4:38 ↗
An absent rectal anal inhibitory reflex means the internal anal sphincter doesn't relax when the rectum is distended, which can contribute to constipation
clinicalFelipe Glu6:35 ↗
Many patients are going to have an abnormal anorectal manometry but they're OK
clinicalMarc Levitt6:47 ↗
Botox helps patients learn to overcome non-relaxing sphincters by other maneuvers like pushing on their abdominal wall
clinicalMarc Levitt6:56 ↗
Many patients are completely asymptomatic doing great with Hirschsprung's that have residual absent rectal anal inhibitory reflex
clinicalMarc Levitt7:11 ↗
In Hirschsprung patients with constipation, the colon is not the problem; the problem usually is the sphincters or the pelvic floor
clinicalMarc Levitt7:39 ↗
If you get an awake anorectal manometry in a cooperative patient with a normal rectal anal inhibitory reflex and can detect the resting pressure, the evaluation is complete without anesthesia or procedure
clinicalMarc Levitt8:14 ↗
If the rectal anal inhibitory reflex is absent, you're obligated to do a biopsy and give Botox
guidelineMarc Levitt8:29 ↗
Botox is given if the resting pressure of the external sphincter is also high
clinicalMarc Levitt8:36 ↗
Pelvic floor dysynergia can be detected on anorectal manometry and is a good indication that pelvic floor physical therapy will help the patient
clinicalMarc Levitt8:41 ↗
Colonic manometry should not be done in Hirschsprung patients with obstructive symptoms because it's not the colon but the distal pull-through that's the problem
guidelineMarc Levitt9:55 ↗
Anatomic and pathologic causes must be ruled out before any colonic manometry is considered
guidelineMarc Levitt10:11 ↗
Colonic manometry in a patient with a distal obstruction is the wrong test
guidelineMarc Levitt10:18 ↗
Once distal obstruction is ruled out or fixed and the colon is still not working, then you have a problem warranting colonic manometry
clinicalJason Frischer10:27 ↗
If there's a segment less than 30 centimeters of inadequate high amplitude propagating contractions, the approach is not super aggressive; over 30 centimeters is definitely more of a red flag
clinicalJason Frischer11:01 ↗
High amplitude propagating contractions aid in the transfer of colonic contents over long distance and often precede emptying
clinicalFelipe Glu11:17 ↗
In a PCPLC Consortium study of close to 100 patients with functional constipation and segmental dysmotility of the sigmoid, 97% successfully responded to Malone only without needing resection
epidemiologicalMarc Levitt11:54 ↗
Five years ago, surgeons were taking sigmoids out of patients with segmental dysmotility, but this practice has changed based on new data
clinicalMarc Levitt12:28 ↗
A Malone procedure is a route for medical treatment, providing antegrade access to the colon for gastroenterologists to give better medical treatment
clinicalMarc Levitt13:24 ↗
While surgery can correct the underlying anatomical problem in Hirschsprung disease, many other factors can contribute to constipation including motility disorders, pelvic floor dysfunction, and behavioral issues
clinicalFelipe Glu14:15 ↗
The Colorectal Quiz Episode 9: Motility Disorders Part 2
Water-soluble contrast enema showed a tortuous and redundant colon that was dilated and full of stool
clinical0:53 ↗
Anorectal manometry showed an absent rectoanal inhibitory reflex (RAIR)
