Two takeaways here, one of which is the ileocecal region. May not be important to preserve and may actually be injurious. And the second point is that administration of a specific bile acid that is more um uh lipophilic and, uh, and more hepatic, uh, I guess, uh, protective could be potential therapy for patients that have cholestatic liver disease after a massive intestinal resection.

Hepatoblastoma
I would accept stool outputs of up to 40 ccs per kilo per day. That's when I would say you're hitting the limits by which you should, you know, back off on your enteral feeding.
quote ·
Abdominal Wall Defects
I think probably dilated bowel loops are one central theme here. That can be responsible not just for the sepsis episodes but for inability to tolerate enteral feeding.
quote ·
Hirschsprung disease
You can do a Bianchi and then go back in and do another step on top of a Bianchi. You can't do a Bianchi once a step has been done.
quote ·
Abdominal Wall Defects
Right now, the survival for small bowel transplant is about 50 to 60% at 5 years.

Colorectal / ARM & Hirschsprung
I always always push the enteral first.

Intestinal Failure with Dr. Brad Warner
Statement
Intestinal failure is an umbrella term for when the small intestine is unable to absorb or digest enough nutrition to support the patient entirely by oral or enteral feeding
Open
Statement
The intestine of a newborn or fetus doubles in length in the last trimester of gestation
Open
Statement
A 24-25 week premature infant with 20-25 cm of bowel will likely increase to at least 50 cm just on the basis of growth alone
Open
Statement
For a neonate with ileocecal valve and entire colon, 10-15 cm of small intestine is a ballpark figure for potential viability
Open
Statement
Without the colon and ileocecal valve, at least 15-20 cm of small intestine would be needed for potential viability in a neonate
Open
Statement
In adult studies, patients with less than 50 cm of intestine have about 40% mortality after 5-10 years
Open
Statement
According to Pediatric Intestinal Failure Research Consortium data, of children on TPN for more than several months due to short gut syndrome: 25% die, 25% need transplant, and 50% can wean off TPN
Open
Statement
Common causes of death in intestinal failure include liver failure, septic episodes from central line or bacterial overgrowth, variceal bleeding from liver disease, and loss of IV access
Open
Statement
Intestinal adaptation in humans probably takes place over about a year or two after small bowel resection
Open
Statement
The goal of management is to wean TPN and push enteral feeding, accepting stool outputs of up to 40 cc per kilo per day as the limit
Open
Quotation
I would accept stool outputs of up to 40 ccs per kilo per day. That's when I would say you're hitting the limits by which you should, you know, back off on your enteral feeding.
Open
Statement
The most common reasons children develop short gut syndrome are necrotizing enterocolitis, gastroschisis, midgut volvulus, and atresias
Open
Statement
For TPN, target about 100-120 calories per kilo per day for total calories, with about 50% from glucose and remainder from fat and protein
Open
Statement
Shoot for about 2-3 g of protein per kilo per day and about 2-3 g of fat per kilo per day in TPN
Open
Statement
Begin enteral feeding as soon as feasible after resection and reanastomosis when they start stooling, generally starting with slow continuous drip
Open
Statement
With continuous drip feeding, nutrient transporters are upregulated and ability to get more nutrition in may be advantageous
Open
Statement
Want a baby to gain about 20-30 g a day, which approximates in utero progression for a newborn
Open
Statement
Lipid reduction strategy takes fat from 2-3 g per kilo per day given daily down to about 1 g per kilo per day delivered twice or 3 times a week, which has been effective in reducing TPN-associated cholestasis
Open
Statement
Omegaven is a fish oil-based fat containing primarily omega-3 fatty acids that are anti-inflammatory, compared to soybean-based intralipid with omega-6 fatty acids that are pro-inflammatory
Open
Statement
When fish oil (omegaven) is introduced to children getting jaundiced, there has been demonstrated significant fall in their jaundice levels
Open
Statement
SMOF lipid contains soybean-based lipid (essential fatty acids), medium chain triglycerides (more easily digested), olive oil, and fish oil, and has recently been FDA approved in the United States
Open
Statement
Breast milk is the best choice for neonates because it contains proper fat, growth factors like EGF and IGF, and milk oligosaccharides that enhance adaptation
Open
Statement
Complex formulas fed enterally may stimulate adaptation better than elemental formulas by causing secretion of enterotrophic hormones to a greater extent
Open
Statement
There is a threshold percentage of enteral calories that prevents onset of liver damage from TPN, with 90% enteral feeding having far less risk of TPN-related cholestasis than 10% enteral
Open
Statement
Time to consider surgical intervention is when enteral tolerance plateaus and then declines (going backward rather than forward), or with multiple sepsis episodes plus abdominal distention and dilated bowel loops, or when child starts getting jaundiced
Open
Quotation
My time that I would be starting to think about doing lengthening procedures or intervening surgically would be is if you hit a point rally and now you start backing away.
Open
Statement
Dilated bowel loops can cause subclinical portal bacteremia contributing to jaundice, and bacterial overgrowth causes secretory diarrhea that impairs enzyme function
Open
Statement
More than 4-5 centimeters of bowel dilation with failure to advance enteral feeds or going backward is an indication for surgical intervention
Open
Statement
If a child has over 100 centimeters of intestine, less than 5-10% should require TPN, suggesting there may be an underlying motility or mucosal problem
Open
Statement
For bowel lengthening, need less than 100 cm (ideally less than 50 cm) of intestine and bowel that is at least 4-5 cm dilated
Open
Statement
The STEP (serial transverse enteroplasty) procedure has emerged as the most commonly performed lengthening operation
Open
Statement
The Bianchi procedure takes advantage of the V-shaped blood supply bifurcation before reaching the bowel wall, allowing creation of two tubes each supplied by one arm of the V
Open
Statement
STEP procedure is easier to perform with less risk of injuring mesenteric blood supply because you only cut partially across the bowel at right angles
Open
Statement
STEP can redilate requiring redo procedures, and outcomes are not as good if you have to redo a STEP compared to never needing a redo
Open
Quotation
You can do a Bianchi and then go back in and do another step on top of a Bianchi. You can't do a Bianchi once a step has been done.
Open
Statement
You can do a Bianchi and then later do a STEP on top of it, but you cannot do a Bianchi once a STEP has been done
Open
Statement
In a case where a STEP was acting as a brake causing dysmotility, removing the distal stepped bowel allowed the patient to completely wean off TPN
Open
Quotation
I really made it a point to say that I think it's the step that is acting as a brake, you know, and they ended up letting me take out the distal bowel.
Open
Quotation
So that makes me feel like steps are not as innocuous as as we think they are, and because of that, I, I don't know, I tend to lean a little bit more as a primary to do a Bianchi, and if I have to redo something, I might, I might do it as a step then
Open
Statement
Would taper a child with dilated bowel who had at least 90-100 centimeters of intestinal length
Open
Statement
Strategies for TPN cholestasis include bile salts (chenodeoxycholic acid), changing lipid composition, and increasing enteral feeds
Open
Statement
Dan Teitelbaum's trial of cholecystokinin to promote bile flow and mitigate TPN cholestasis did not work
Open
Statement
Dilated bowel is a nidus for infection encouraging translocation of bacteria and endotoxin into portal circulation, damaging the liver
Open
Statement
Medical management of bacterial overgrowth includes oral antibiotics (Cipro, Flagyl), probiotics (lactobacilli), prebiotics, and potentially fecal transplantation
Open
Statement
The gut bacteria in short gut syndrome become more efficient, creating an obesogenic-like microbiome that helps adapt by encouraging greater absorption and digestion
Open
Statement
In mouse studies, oral vancomycin to knock out gram-positive organisms completely prevented hepatic steatosis after bowel resection
Open
Statement
Teduglutide (GLP-2 analog) has been shown in randomized prospective trials in adults to reduce TPN requirements by about 1-2 liters per week
Open
Statement
Teduglutide is not yet approved for children in the United States, with concerns about malignancy risk due to promoting proliferation
Open
Statement
Growth factors shown to promote adaptation in animal studies include EGF, HB-EGF (demonstrated by Gail Bessner), interleukins, and growth hormone with glutamine
Open
Statement
Growth hormone and glutamine combinations in patients have shown primarily mixed results and are expensive
Open
Statement
Survival for small bowel transplant is about 50-60% at 5 years, with one-year survivals now above 70-80%
Open
Statement
The intestine is highly immunogenic, filled with white cells and macrophages that mount a huge graft-versus-host response, requiring industrial strength immunosuppression
Open
Statement
Ethanol locks for central lines have significantly reduced the number of sepsis episodes in patients with short gut syndrome who have Broviac catheters
Open
Quotation
I think if they're doing well. Um, and they're not jaundiced, um, doing it for the sake of getting them off of TPN may be a bit premature if they're, if they're otherwise doing well
Open

Quotation
In looking for mechanisms as to how this occurs, we sought to determine whether bile acids or the site of intestinal resection would really make a difference in terms of the liver injury.
Open
Statement
The ileocecal region may not be important to preserve in short bowel syndrome and may actually be injurious
Open
Quotation
Two takeaways here, one of which is the ileocecal region. May not be important to preserve and may actually be injurious. And the second point is that administration of a specific bile acid that is more um uh lipophilic and, uh, and more hepatic, uh, I guess, uh, protective could be potential therapy for patients that have cholestatic liver disease after a massive intestinal resection.

Intestinal Failure with Dr. Brad Warner
Statement
Intestinal failure is an umbrella term for when the small intestine is unable to absorb or digest enough nutrition to support the patient entirely by oral or enteral feeding.
Open
Statement
The intestine of a newborn or fetus doubles in length in the last trimester of gestation.
Open
Statement
For a neonate with an ileocecal valve and entire colon, 10 to 15 centimeters of small intestine is a ballpark figure for potential salvageability.
Open
Statement
Without the colon and ileocecal valve, at least 15 to 20 centimeters of small intestine would be needed for potential salvageability in neonates.
Open
Statement
In adult studies, adults with less than 50 centimeters of intestine have about 40% mortality after 5 to 10 years.
Open
Statement
According to Pediatric Intestinal Failure Research Consortium data, approximately 25% of children with short gut syndrome die, 25% need a transplant, and 50% can wean off TPN.
Open
Statement
The most common causes of death in intestinal failure include liver failure, septic episodes from central line or bacterial overgrowth, variceal bleeding from liver disease, and loss of IV access.
Open
Statement
Intestinal adaptation in humans probably takes place over about a year or two after small bowel resection.
Open
Quotation
I would accept stool outputs of up to 40 ccs per kilo per day. That's when I would say you're hitting the limits by which you should, you know, back off on your enteral feeding.
Open
Statement
Stool outputs of up to 40 cc per kilo per day are acceptable when advancing enteral feeding; beyond that threshold, enteral feeding should be reduced.
Open
Statement
The most common causes of short gut syndrome are necrotizing enterocolitis, gastroschisis, midgut volvulus, and atresias, with trauma and inflammatory bowel disease further down the list.
Open
Statement
For TPN, the goal is about 100 to 120 calories per kilo per day for total calories, with about 50% from glucose and the remainder from fat and protein.
Open
Statement
TPN should provide about 2 to 3 grams of protein per kilo per day and about 2 to 3 grams of fat per kilo per day.
Open
Statement
Babies should gain about 20 to 30 grams a day, which approximates in utero weight gain for a newborn.
Open
Statement
Lipid reduction strategy involves reducing fat from 2-3 g/kg/day given daily down to about 1 g/kg/day delivered twice or three times a week, which has been effective in reducing TPN-associated cholestasis.

Open
Statement
Dilated bowel loops greater than 4 to 5 centimeters in diameter, combined with failure to advance enteral feeds or regression, is an indication for surgical intervention.
Open
Statement
Less than 5 to 10% of patients with over 100 centimeters of intestine should require TPN, suggesting an underlying motility or mucosal problem if they remain TPN-dependent.
Open
Statement
The STEP (serial transverse enteroplasty) procedure has emerged as the most commonly performed lengthening operation because it is easier to perform with less risk of injuring the mesenteric blood supply.
Open
Statement
The Bianchi procedure takes advantage of the bifurcating blood supply to the bowel wall, allowing longitudinal division to create two tubes of bowel, effectively doubling the length.
Open
Statement
STEP procedures can redilate and require redo operations, and outcomes are not as good when a STEP needs to be redone compared to never needing a redo.

You can do a Bianchi and then go back in and do another step on top of a Bianchi. You can't do a Bianchi once a step has been done.
Open
Statement
A Bianchi can be performed first, then a STEP can be done later if needed, but a Bianchi cannot be done after a STEP has been performed (unless the STEP was inadequate).
Open

Intestinal Failure with Dr. Brad Warner
Statement
Intestinal failure is an umbrella term for when the small intestine is unable to absorb or digest enough nutrition to support the patient entirely by oral or enteral feeding
Open
Statement
The intestine of a newborn or fetus doubles in length in the last trimester of gestation
Open
Statement
A 24-25 week premature infant with 20-25 cm of bowel will likely increase to at least 50 cm just on the basis of growth alone
Open
Statement
For a neonate with ileocecal valve and entire colon, 10-15 cm of small intestine is a ballpark figure for potential viability
Open
Statement
Without the colon and ileocecal valve, at least 15-20 cm of small intestine would be needed for potential viability in a neonate
Open
Statement
In adult studies, patients with less than 50 cm of intestine have about 40% mortality after 5-10 years
Open
Statement
According to Pediatric Intestinal Failure Research Consortium data, of children on TPN for more than several months due to short gut syndrome: 25% die, 25% need transplant, and 50% can wean off TPN
Open
Statement
Common causes of death in intestinal failure include liver failure, septic episodes from central line or bacterial overgrowth, variceal bleeding from liver disease, and loss of IV access
Open
Statement
Intestinal adaptation in humans probably takes place over about a year or two after small bowel resection
Open
Statement
The goal of management is to wean TPN and push enteral feeding, accepting stool outputs of up to 40 cc per kilo per day as the limit
Open
Quotation
I would accept stool outputs of up to 40 ccs per kilo per day. That's when I would say you're hitting the limits by which you should, you know, back off on your enteral feeding.
Open
Statement
The most common reasons children develop short gut syndrome are necrotizing enterocolitis, gastroschisis, midgut volvulus, and atresias
Open
Statement
For TPN, target about 100-120 calories per kilo per day for total calories, with about 50% from glucose and remainder from fat and protein
Open
Statement
Shoot for about 2-3 g of protein per kilo per day and about 2-3 g of fat per kilo per day in TPN
Open
Statement
Begin enteral feeding as soon as feasible after resection and reanastomosis when they start stooling, generally starting with slow continuous drip
Open
Statement
With continuous drip feeding, nutrient transporters are upregulated and ability to get more nutrition in may be advantageous
Open
Statement
Want a baby to gain about 20-30 g a day, which approximates in utero progression for a newborn
Open

Breast milk is the best choice for neonates because it contains proper fat, growth factors like EGF and IGF, and milk oligosaccharides that enhance adaptation
Open
Statement
Complex formulas fed enterally may stimulate adaptation better than elemental formulas by causing secretion of enterotrophic hormones to a greater extent
Open
Statement
There is a threshold percentage of enteral calories that prevents onset of liver damage from TPN, with 90% enteral feeding having far less risk of TPN-related cholestasis than 10% enteral
Open
Quotation
My time that I would be starting to think about doing lengthening procedures or intervening surgically would be is if you hit a point rally and now you start backing away.
Open
Statement
Time to consider surgical intervention is when enteral tolerance plateaus and then declines (going backward rather than forward), or with multiple sepsis episodes plus abdominal distention and dilated bowel loops, or when child starts getting jaundiced
Open
Statement
Dilated bowel loops can cause subclinical portal bacteremia contributing to jaundice, and bacterial overgrowth causes secretory diarrhea that impairs enzyme function
Open
Statement
More than 4-5 centimeters of bowel dilation with failure to advance enteral feeds or going backward is an indication for surgical intervention
Open

According to Pediatric Intestinal Failure Research Consortium data, of children on TPN for more than several months due to short gut syndrome: 25% die, 25% need transplant, and 50% can wean off TPN
Open
Statement
Common causes of death in intestinal failure include liver failure, septic episodes from central line or bacterial overgrowth, variceal bleeding from liver disease, and loss of IV access
Open
Statement
Intestinal adaptation in humans probably takes place over about a year or two after small bowel resection
Open
Statement
The goal of management is to wean TPN and push enteral feeding, accepting stool outputs of up to 40 cc per kilo per day as the limit
Open
Quotation
I would accept stool outputs of up to 40 ccs per kilo per day. That's when I would say you're hitting the limits by which you should, you know, back off on your enteral feeding.
Open
Statement
The most common reasons children develop short gut syndrome are necrotizing enterocolitis, gastroschisis, midgut volvulus, and atresias
Open
Statement
For TPN, target about 100-120 calories per kilo per day for total calories, with about 50% from glucose and remainder from fat and protein
Open
Statement
Shoot for about 2-3 g of protein per kilo per day and about 2-3 g of fat per kilo per day in TPN
Open
Statement
Begin enteral feeding as soon as feasible after resection and reanastomosis when they start stooling, generally starting with slow continuous drip
Open
Statement
With continuous drip feeding, nutrient transporters are upregulated and ability to get more nutrition in may be advantageous
Open
Statement
Want a baby to gain about 20-30 g a day, which approximates in utero progression for a newborn
Open
Statement
Lipid reduction strategy takes fat from 2-3 g per kilo per day given daily down to about 1 g per kilo per day delivered twice or 3 times a week, which has been effective in reducing TPN-associated cholestasis
Open
Statement
Omegaven is a fish oil-based fat containing primarily omega-3 fatty acids that are anti-inflammatory, compared to soybean-based intralipid with omega-6 fatty acids that are pro-inflammatory
Open
Statement
When fish oil (omegaven) is introduced to children getting jaundiced, there has been demonstrated significant fall in their jaundice levels
Open
Statement
SMOF lipid contains soybean-based lipid (essential fatty acids), medium chain triglycerides (more easily digested), olive oil, and fish oil, and has recently been FDA approved in the United States
Open
Statement
Breast milk is the best choice for neonates because it contains proper fat, growth factors like EGF and IGF, and milk oligosaccharides that enhance adaptation
Open
Statement
Complex formulas fed enterally may stimulate adaptation better than elemental formulas by causing secretion of enterotrophic hormones to a greater extent
Open
Statement
There is a threshold percentage of enteral calories that prevents onset of liver damage from TPN, with 90% enteral feeding having far less risk of TPN-related cholestasis than 10% enteral
Open
Quotation
My time that I would be starting to think about doing lengthening procedures or intervening surgically would be is if you hit a point rally and now you start backing away.
Open
Statement
Time to consider surgical intervention is when enteral tolerance plateaus and then declines (going backward rather than forward), or with multiple sepsis episodes plus abdominal distention and dilated bowel loops, or when child starts getting jaundiced
Open
Statement
Dilated bowel loops can cause subclinical portal bacteremia contributing to jaundice, and bacterial overgrowth causes secretory diarrhea that impairs enzyme function
Open
Statement
More than 4-5 centimeters of bowel dilation with failure to advance enteral feeds or going backward is an indication for surgical intervention
Open
Statement
If a child has over 100 centimeters of intestine, less than 5-10% should require TPN, suggesting there may be an underlying motility or mucosal problem
Open
Statement
For bowel lengthening, need less than 100 cm (ideally less than 50 cm) of intestine and bowel that is at least 4-5 cm dilated
Open
Statement
The STEP (serial transverse enteroplasty) procedure has emerged as the most commonly performed lengthening operation
Open
Statement
The Bianchi procedure takes advantage of the V-shaped blood supply bifurcation before reaching the bowel wall, allowing creation of two tubes each supplied by one arm of the V
Open
Statement
STEP procedure is easier to perform with less risk of injuring mesenteric blood supply because you only cut partially across the bowel at right angles
Open
Statement
STEP can redilate requiring redo procedures, and outcomes are not as good if you have to redo a STEP compared to never needing a redo
Open
Statement
You can do a Bianchi and then later do a STEP on top of it, but you cannot do a Bianchi once a STEP has been done
Open
Quotation
You can do a Bianchi and then go back in and do another step on top of a Bianchi. You can't do a Bianchi once a step has been done.
Open
Statement
In a case where a STEP was acting as a brake causing dysmotility, removing the distal stepped bowel allowed the patient to completely wean off TPN
Open
Quotation
I really made it a point to say that I think it's the step that is acting as a brake, you know, and they ended up letting me take out the distal bowel.
Open
Quotation
So that makes me feel like steps are not as innocuous as as we think they are, and because of that, I, I don't know, I tend to lean a little bit more as a primary to do a Bianchi, and if I have to redo something, I might, I might do it as a step then
Open
Statement
Would taper a child with dilated bowel who had at least 90-100 centimeters of intestinal length
Open
Statement
Strategies for TPN cholestasis include bile salts (chenodeoxycholic acid), changing lipid composition, and increasing enteral feeds
Open
Statement
Dan Teitelbaum's trial of cholecystokinin to promote bile flow and mitigate TPN cholestasis did not work
Open
Statement
Dilated bowel is a nidus for infection encouraging translocation of bacteria and endotoxin into portal circulation, damaging the liver
Open
Statement
Medical management of bacterial overgrowth includes oral antibiotics (Cipro, Flagyl), probiotics (lactobacilli), prebiotics, and potentially fecal transplantation
Open
Statement
The gut bacteria in short gut syndrome become more efficient, creating an obesogenic-like microbiome that helps adapt by encouraging greater absorption and digestion
Open
Statement
In mouse studies, oral vancomycin to knock out gram-positive organisms completely prevented hepatic steatosis after bowel resection
Open
Statement
Teduglutide (GLP-2 analog) has been shown in randomized prospective trials in adults to reduce TPN requirements by about 1-2 liters per week
Open
Statement
Teduglutide is not yet approved for children in the United States, with concerns about malignancy risk due to promoting proliferation
Open
Statement
Growth factors shown to promote adaptation in animal studies include EGF, HB-EGF (demonstrated by Gail Bessner), interleukins, and growth hormone with glutamine
Open
Statement
Growth hormone and glutamine combinations in patients have shown primarily mixed results and are expensive
Open
Statement
Survival for small bowel transplant is about 50-60% at 5 years, with one-year survivals now above 70-80%
Open
Statement
The intestine is highly immunogenic, filled with white cells and macrophages that mount a huge graft-versus-host response, requiring industrial strength immunosuppression
Open
Statement
Ethanol locks for central lines have significantly reduced the number of sepsis episodes in patients with short gut syndrome who have Broviac catheters
Open
Quotation
I think if they're doing well. Um, and they're not jaundiced, um, doing it for the sake of getting them off of TPN may be a bit premature if they're, if they're otherwise doing well
Open
Statement
Multidisciplinary teams including pharmacists, nutritionists, surgeons, GI doctors, ID specialists, and interventional radiologists improve survival in intestinal failure patients, as demonstrated in series from Boston, Michigan, and Texas
