You can get extraordinary length on this. And Mike and I have done a few cases for kids who had disasters, multiple operations elsewhere, who had caustic injuries that were involved all the way up to the pharynx, where we had to do a lot of work just on the pharynx to get that open, and then literally sew the colon interposition to the pharynx and then down to the stomach, which is obviously tough to do with a gastric pull-up.

Our method here is that if we have a child with no gas in the abdomen and we take them to the OR and put a G-tube in, many times we'll do, we'll put something up the distal esophagus at that point and just get a fluoro shot. But then we'd wait a couple of weeks and we have our patients go down to interventional radiology where we have a protocol for measuring the gap.

Ep 1 · 1:07
clinical When considering neuroblastoma as part of the differential diagnosis, it is important to get catecholamines (either urine or serum) as one of the most diagnostic laboratory tests for this tumor.
Ep 1 · 1:39
clinical The MIBG study is helpful for confirming the diagnosis of neuroblastoma and can also demonstrate metastatic disease.
Ep 1 · 1:39
clinical Most children with suspected neuroblastoma would get a cross-sectional imaging study, either a CT scan or an MRI.
Ep 1 · 1:39
clinical If imaging suggests neuroblastoma (central abdominal mass or adrenal mass rather than kidney mass), the next test would be a nuclear medicine study, typically an MIBG study.
Ep 1 · 2:20
clinical Some centers, including Cincinnati Children's Hospital, would get a PET scan looking for tumor uptake as well as potential metastatic disease.
Ep 1 · 2:20

guideline There is a special category MS for children less than 18 months of age who have metastases to either the bone marrow or the skin.
Ep 1 · 2:45
guideline In the INRGSS system, tumors that are localized are categorized as L1; if localized but have image-defined risk factors (encasing nerves or vessels), they are L2; if they have metastatic disease, they are M.
Ep 1 · 2:45
guideline Based on the most recent iteration of the neuroblastoma staging system (INRGSS), it is possible to assign a stage before any invasive procedure is performed.
Ep 1 · 3:36
guideline The prior neuroblastoma staging system required tissue diagnosis before assigning a stage.
Ep 1 · 3:36
guideline The INRGSS pre-biopsy staging system was specifically created to allow studies from different centers in different countries to be compared based on the pre-surgical staging of the patient.
Ep 1 · 4:06
opinion Some surgeons would approach resection of a localized neuroblastoma with laparoscopy depending on the size of the tumor.
Ep 1 · 4:06
clinical A child with an adrenal mass on the right side and a positive MIBG scan but no evidence of metastases could potentially be treated with a primary resection of the mass via laparotomy.
Ep 1 · 4:44
clinical For very large masses that encase the aorta, cava, or other major vasculature, all you really want is tissue for diagnosis, which can be obtained through open biopsy, laparoscopic biopsy, or core needle biopsies done by an interventional radiologist.
Ep 1 · 5:14
clinical The most important biologic risk determinant to obtain from neuroblastoma biopsy tissue is the NMIC status.
Ep 1 · 5:14
clinical In addition to NMIC status, you want to look for 1P and 11Q deletions and Shimada histology in neuroblastoma biopsy tissue.
Ep 1 · 5:45
epidemiological Neuroblastoma risk is divided about 50-50 between the low risk categories and the high risk category, with a smaller percentage being intermediate risk.
Ep 1 · 5:45
clinical Biologic risk determinants from biopsy will tell you what risk category the patient falls into: very low risk, low risk, intermediate risk, or high risk.
Ep 1 · 6:11
clinical NMIC amplification and age greater than 18 months are the most important prognostic determinants for neuroblastoma.
Ep 1 · 6:11
clinical Patients with high risk neuroblastoma receive aggressive chemotherapy including peripheral stem cell transplant times 2, aggressive surgery with the goal of greater than 90% resection of the tumor, followed by radiation, immunotherapy after chemotherapy, and potentially retinoic acid therapy.
Ep 1 · 6:11
quote NMIC and age greater than 18 months are the most important prognostic determinants for neuroblastoma.
Ep 1 · 6:51
clinical For intermediate risk neuroblastoma, the goal at the time of debulking or resecting the primary tumor is to achieve at least a 50% response from the initial volume of the primary tumor through the combination of neoadjuvant chemotherapy and surgical resection.
Ep 1 · 6:51
clinical Intermediate risk neuroblastoma tumors get varying cycles of chemotherapy based on the biologic risk factors they have.
Ep 1 · 7:22
clinical The low risk neuroblastoma group, depending on the actual age of the patient and how it is diagnosed, could potentially be followed simply with observation.
Ep 1 · 7:22
clinical Jed Nocturne led a study through the Children's Oncology Group looking at patients less than six months of age with either a prenatally diagnosed or shortly postnatally diagnosed localized mass, showing these patients can be observed with the expectation that the vast majority will avoid any type of surgical procedure.
Ep 1 · 7:55
clinical MS disease is specifically for patients who have a primary site with metastatic disease to the liver, the skin, or the bone marrow (specifically not bone, not cortical bone) and is less than 18 months of age.
Ep 1 · 7:55
clinical If the tumor and metastatic disease are responding to neoadjuvant chemotherapy, one would attack the primary tumor site with a resection, with many advocating for attempting a greater than 90% resection.
Ep 1 · 7:55
clinical Patients with metastatic neuroblastoma typically receive four or five cycles of neoadjuvant chemotherapy and then are reassessed.
Ep 1 · 7:55
quote MS disease is specifically for patients who have a primary site with metastatic disease to the liver, the skin, or the bone marrow, specifically not bone, not cortical bone, and is less than 18 months of age.
Ep 1 · 7:55
clinical In patients with MS disease, simple observation can be the treatment path.
Ep 1 · 7:55
clinical If the metastatic disease is progressing on neoadjuvant chemotherapy, then surgery is not indicated.
Ep 1 · 7:55
clinical If MS disease patients progress or develop respiratory issues because of an enlarging liver mass, treatment might be elected because of the complication of the size of the tumor, but the tumor itself usually does not have to be treated.
Ep 1 · 8:55
clinical You can biopsy the skin lesions in MS disease and that will give you the diagnosis.

Treatment for Long Gap Esophageal Atresia: Esophageal Elongation and Replacement

Ep 2 · 0:46
quote Our method here is that if we have a child with no gas in the abdomen and we take them to the OR and put a G-tube in, many times we'll do, we'll put something up the distal esophagus at that point and just get a fluoro shot. But then we'd wait a couple of weeks and we have our patients go down to interventional radiology where we have a protocol for measuring the gap.
Ep 2 · 0:46

Ep 2 · 9:03
clinical You can get extraordinary length with colonic interposition, allowing treatment of cases with caustic injuries extending to the pharynx by sewing the colon to the pharynx and down to the stomach, which is tough to do with a gastric pull-up.
Ep 2 · 9:03
quote You can get extraordinary length on this. And Mike and I have done a few cases for kids who had disasters, multiple operations elsewhere, who had caustic injuries that were involved all the way up to the pharynx, where we had to do a lot of work just on the pharynx to get that open, and then literally sew the colon interposition to the pharynx and then down to the stomach, which is obviously tough to do with a gastric pull-up.
Ep 2 · 9:56
quote I don't think we know we should do the studies to understand that. But I would say that this gets back to David van der Zee's comment about, go have a cup of coffee and come back and it'll be fine. Clearly, that's not growth, that's stretch.
Ep 2 · 9:56
opinion Von Allman states we don't know whether esophageal elongation is growth or stretch and should do studies to understand that, but notes that tension is a very good physiologic growth promoter in other organs, making this an area ripe for more basic science.
Ep 2 · 9:56
quote And yet there's very good physiologic data that tension is a growth promoter, not necessarily in the esophagus, but in other organs. So I think that it's an area ripe for a little more basic science.

clinical When considering neuroblastoma as part of the differential diagnosis, it is important to get catecholamines (either urine or serum) as one of the most diagnostic laboratory tests for this tumor.
Ep 1 · 1:39
clinical The MIBG study is helpful for confirming the diagnosis of neuroblastoma and can also demonstrate metastatic disease.
Ep 1 · 1:39
clinical If imaging suggests neuroblastoma (central abdominal mass or adrenal mass rather than kidney mass), the next test would be a nuclear medicine study, typically an MIBG study.
Ep 1 · 1:39

guideline There is a special category MS for children less than 18 months of age who have metastases to either the bone marrow or the skin.
Ep 1 · 2:45
guideline In the INRGSS system, tumors that are localized are categorized as L1; if localized but have image-defined risk factors (encasing nerves or vessels), they are L2; if they have metastatic disease, they are M.
Ep 1 · 2:45
guideline Based on the most recent iteration of the neuroblastoma staging system (INRGSS), it is possible to assign a stage before any invasive procedure is performed.
Ep 1 · 3:36
guideline The INRGSS pre-biopsy staging system was specifically created to allow studies from different centers in different countries to be compared based on the pre-surgical staging of the patient.
Ep 1 · 3:36
guideline The prior neuroblastoma staging system required tissue diagnosis before assigning a stage.
Ep 1 · 4:06
opinion Some surgeons would approach resection of a localized neuroblastoma with laparoscopy depending on the size of the tumor.
Ep 1 · 4:06
clinical A child with an adrenal mass on the right side and a positive MIBG scan but no evidence of metastases could potentially be treated with a primary resection of the mass via laparotomy.
Ep 1 · 4:44
clinical For very large masses that encase the aorta, cava, or other major vasculature, all you really want is tissue for diagnosis, which can be obtained through open biopsy, laparoscopic biopsy, or core needle biopsies done by an interventional radiologist.
Ep 1 · 5:14
clinical The most important biologic risk determinant to obtain from neuroblastoma biopsy tissue is the NMIC status.
Ep 1 · 5:14
clinical In addition to NMIC status, you want to look for 1P and 11Q deletions and Shimada histology in neuroblastoma biopsy tissue.
Ep 1 · 5:45
epidemiological Neuroblastoma risk is divided about 50-50 between the low risk categories and the high risk category, with a smaller percentage being intermediate risk.

clinical Biologic risk determinants from biopsy will tell you what risk category the patient falls into: very low risk, low risk, intermediate risk, or high risk.
Ep 1 · 6:11
quote NMIC and age greater than 18 months are the most important prognostic determinants for neuroblastoma.
Ep 1 · 6:11
clinical Patients with high risk neuroblastoma receive aggressive chemotherapy including peripheral stem cell transplant times 2, aggressive surgery with the goal of greater than 90% resection of the tumor, followed by radiation, immunotherapy after chemotherapy, and potentially retinoic acid therapy.
Ep 1 · 6:11
clinical NMIC amplification and age greater than 18 months are the most important prognostic determinants for neuroblastoma.
Ep 1 · 6:51
clinical Intermediate risk neuroblastoma tumors get varying cycles of chemotherapy based on the biologic risk factors they have.
Ep 1 · 6:51
clinical For intermediate risk neuroblastoma, the goal at the time of debulking or resecting the primary tumor is to achieve at least a 50% response from the initial volume of the primary tumor through the combination of neoadjuvant chemotherapy and surgical resection.
Ep 1 · 7:22
clinical The low risk neuroblastoma group, depending on the actual age of the patient and how it is diagnosed, could potentially be followed simply with observation.
Ep 1 · 7:22
clinical Jed Nocturne led a study through the Children's Oncology Group looking at patients less than six months of age with either a prenatally diagnosed or shortly postnatally diagnosed localized mass, showing these patients can be observed with the expectation that the vast majority will avoid any type of surgical procedure.

quote MS disease is specifically for patients who have a primary site with metastatic disease to the liver, the skin, or the bone marrow, specifically not bone, not cortical bone, and is less than 18 months of age.
Ep 1 · 7:55
clinical If MS disease patients progress or develop respiratory issues because of an enlarging liver mass, treatment might be elected because of the complication of the size of the tumor, but the tumor itself usually does not have to be treated.
Ep 1 · 7:55
clinical In patients with MS disease, simple observation can be the treatment path.
Ep 1 · 7:55
clinical MS disease is specifically for patients who have a primary site with metastatic disease to the liver, the skin, or the bone marrow (specifically not bone, not cortical bone) and is less than 18 months of age.
Ep 1 · 7:55
clinical Patients with metastatic neuroblastoma typically receive four or five cycles of neoadjuvant chemotherapy and then are reassessed.
Ep 1 · 7:55
clinical If the metastatic disease is progressing on neoadjuvant chemotherapy, then surgery is not indicated.
Ep 1 · 7:55
clinical If the tumor and metastatic disease are responding to neoadjuvant chemotherapy, one would attack the primary tumor site with a resection, with many advocating for attempting a greater than 90% resection.
Ep 1 · 8:55
clinical You can biopsy the skin lesions in MS disease and that will give you the diagnosis.

Treatment for Long Gap Esophageal Atresia: Esophageal Elongation and Replacement

Ep 2 · 0:46
quote Our method here is that if we have a child with no gas in the abdomen and we take them to the OR and put a G-tube in, many times we'll do, we'll put something up the distal esophagus at that point and just get a fluoro shot. But then we'd wait a couple of weeks and we have our patients go down to interventional radiology where we have a protocol for measuring the gap.
Ep 2 · 0:46

Ep 2 · 8:17
clinical Von Allman passes the colonic interposition posterior to the stomach, which leaves the vascular pedicle along the spine, allowing mobilization of the colon by dividing the gastric duodenotomy and colon attachment to the stomach, then mobilizing the sigmoid redundancy transhiatally and reanastomosing the colon to the stomach.
Ep 2 · 8:17
quote So I wouldn't pretend to say that these don't need to be revised sometimes, but it is not impossible to revise them and the kids tend to do pretty well.

quote I pass the interposition posterior to the stomach, which leaves the vascular pedicle along the spine. And you can mobilize the colon. You can divide the gastric dual aporotomy, divide the colon attachment to the stomach, and then mobilize that sigmoid redundancy transhiatally, and then reinestimose the colon to the stomach.
Ep 2 · 8:17
quote I was taught initially that you can't fix that and that it's too dangerous and that you'll risk the blood supply to the colon interposition. But I found that actually that's not really true.

opinion Colonic interpositions sometimes need to be revised, but it is not impossible to revise them and the kids tend to do pretty well.
Ep 2 · 9:03
quote You can get extraordinary length on this. And Mike and I have done a few cases for kids who had disasters, multiple operations elsewhere, who had caustic injuries that were involved all the way up to the pharynx, where we had to do a lot of work just on the pharynx to get that open, and then literally sew the colon interposition to the pharynx and then down to the stomach, which is obviously tough to do with a gastric pull-up.
Ep 2 · 9:03
clinical You can get extraordinary length with colonic interposition, allowing treatment of cases with caustic injuries extending to the pharynx by sewing the colon to the pharynx and down to the stomach, which is tough to do with a gastric pull-up.
Ep 2 · 9:56
quote I don't think we know we should do the studies to understand that. But I would say that this gets back to David van der Zee's comment about, go have a cup of coffee and come back and it'll be fine. Clearly, that's not growth, that's stretch.
Ep 2 · 9:56
quote And yet there's very good physiologic data that tension is a growth promoter, not necessarily in the esophagus, but in other organs. So I think that it's an area ripe for a little more basic science.
Ep 2 · 9:56
opinion Von Allman states we don't know whether esophageal elongation is growth or stretch and should do studies to understand that, but notes that tension is a very good physiologic growth promoter in other organs, making this an area ripe for more basic science.
